                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, October 1, 2023), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not dropped in error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

Sec.  20.3  Definitions.

    Automatic Roaming. With automatic roaming, under a pre-existing 
contractual agreement between a subscriber's home carrier and a host 
carrier, a roaming subscriber is able to originate or terminate a call 
in the host carrier's service area without taking any special actions.
    CIS Operator. An operator of a CIS at a correctional facility, 
whether a CIS solutions provider, or a DCFO or responsible party that 
deploys its own CIS at a correctional facility.
    Commercial mobile data service. (1) Any mobile data service that is 
not interconnected with the public switched network and is:
    (i) Provided for profit; and
    (ii) Available to the public or to such classes of eligible users as 
to be effectively available to the public.
    (2) Commercial mobile data service includes services provided by 
Mobile Satellite Services and Ancillary Terrestrial Component providers 
to the extent the services provided meet this definition.
    Commercial mobile radio service. A mobile service that is:
    (a)(1) provided for profit, i.e., with the intent of receiving 
compensation or monetary gain;
    (2) An interconnected service; and

[[Page 6]]

    (3) Available to the public, or to such classes of eligible users as 
to be effectively available to a substantial portion of the public; or
    (b) The functional equivalent of such a mobile service described in 
paragraph (a) of this definition.
    (c) A variety of factors may be evaluated to make a determination 
whether the mobile service in question is the functional equivalent of a 
commercial mobile radio service, including: Consumer demand for the 
service to determine whether the service is closely substitutable for a 
commercial mobile radio service; whether changes in price for the 
service under examination, or for the comparable commercial mobile radio 
service, would prompt customers to change from one service to the other; 
and market research information identifying the targeted market for the 
service under review.
    (d) Unlicensed radio frequency devices under part 15 of this chapter 
are excluded from this definition of Commercial mobile radio service.
    Consumer Signal Booster. A bi-directional signal booster that is 
marketed and sold for use without modification.
    Contraband Interdiction System. A Contraband Interdiction System 
(CIS) is any system comprised of one or more stations that is used only 
at a permanent correctional facility that is authorized to operate such 
systems pursuant to this part and that is designed exclusively to 
prevent transmissions to or from contraband wireless devices within the 
boundaries of the facility and/or to obtain identifying information from 
such contraband wireless devices.
    Designated Correctional Facility Official. A Designated Correctional 
Facility Official (DCFO) is an official of the state, local, or Federal 
government responsible for administration and oversight of the relevant 
correctional facility where a contraband wireless device is located.
    (1) In government-run correctional facilities, this definition 
requires the DCFO to be, at a minimum, the official with responsibility 
for oversight of the relevant facility (e.g., the warden) or higher 
ranking official.
    (2) In privately-run correctional facilities, this definition 
requires the DCFO to be a government official with responsibility for 
oversight of the facility's performance through contract.
    Fixed Consumer Signal Booster. A Consumer Signal Booster designed to 
be operated in a fixed location in a building.
    Host Carrier. For automatic roaming, the host carrier is a 
facilities-based CMRS carrier on whose system another carrier's 
subscriber roams. A facilities-based CMRS carrier may, on behalf of its 
subscribers, request automatic roaming service from a host carrier.
    Incumbent Wide Area SMR Licensees. Licensees who have obtained 
extended implementation authorizations in the 800 MHz or 900 MHz 
service, either by waiver or under Section 90.629 of these rules, and 
who offer real-time, two-way voice service that is interconnected with 
the public switched network.
    Industrial Signal Booster: All signal boosters other than Consumer 
Signal Boosters.
    Interconnection or Interconnected. Direct or indirect connection 
through automatic or manual means (by wire, microwave, or other 
technologies such as store and forward) to permit the transmission or 
reception of messages or signals to or from points in the public 
switched network.
    Interconnected Service. A service:
    (a) That is interconnected with the public switched network, or 
interconnected with the public switched network through an 
interconnected service provider, that gives subscribers the capability 
to communicate to or receive communication from all other users on the 
public switched network; or
    (b) For which a request for such interconnection is pending pursuant 
to section 332(c)(1)(B) of the Communications Act, 47 U.S.C. 
332(c)(1)(B). A mobile service offers interconnected service even if the 
service allows subscribers to access the public switched network only 
during specified hours of the day, or if the service provides general 
access to points on the public switched network but also restricts 
access in certain limited ways. Interconnected service does not include 
any interface between a licensee's facilities

[[Page 7]]

and the public switched network exclusively for a licensee's internal 
control purposes.
    Managed Access System. A Managed Access System (MAS) is a Contraband 
Interdiction System whose operations require:
    (1) One or more lease agreements with CMRS operators; and
    (2) Real-time awareness of wireless provider spectrum use in the 
vicinity of the correctional facility where it is deployed.
    Manual Roaming. With manual roaming, a subscriber must establish a 
relationship with the host carrier on whose system he or she wants to 
roam in order to make a call. Typically, the roaming subscriber 
accomplishes this in the course of attempting to originate a call by 
giving a valid credit card number to the carrier providing the roaming 
service.
    Mobile Consumer Signal Booster. A Consumer Signal Booster designed 
to operate in a moving vehicle where both uplink and downlink 
transmitting antennas are at least 20 cm from the user or any other 
person.
    Mobile Service. A radio communication service carried on between 
mobile stations or receivers and land stations, and by mobile stations 
communicating among themselves, and includes:
    (a) Both one-way and two-way radio communications services;
    (b) A mobile service which provides a regularly interacting group of 
base, mobile, portable, and associated control and relay stations 
(whether licensed on an individual, cooperative, or multiple basis) for 
private one-way or two-way land mobile radio communications by eligible 
users over designated areas of operation; and
    (c) Any service for which a license is required in a personal

Sec.  20.5  Citizenship.

    (a) This rule implements section 310 of the Communications Act, 47 
U.S.C. 310, regarding the citizenship of licensees in the commercial 
mobile radio services. Commercial mobile radio service authorizations 
may not be granted to or held by:
    (1) Any foreign government or any representative thereof;
    (2) Any alien or the representative of any alien;
    (3) Any corporation organized under the laws of any foreign 
government;
    (4) Any corporation of which more than one-fifth of the capital 
stock is owned of record or voted by aliens or their representatives or 
by a foreign government or representative thereof or by any corporation 
organized under the laws of a foreign country; or
    (5) Any corporation directly or indirectly controlled by any other 
corporation of which more than one-fourth of the capital stock is owned 
of record or voted by aliens, their representatives, or by a foreign 
government or representative thereof, or by any corporation organized 
under the laws of a foreign country, if the Commission finds that the 
public interest will be served by the refusal or revocation of such 
license.
    (b) The limits listed in paragraph (a) of this section may be 
exceeded by eligible individuals who held ownership interests on May 24, 
1993, pursuant to the waiver provisions established in section 332(c)(6)

Sec.  20.6  CMRS spectrum aggregation limit.

    (a) Spectrum limitation. No licensee in the broadband PCS, cellular, 
or SMR services (including all parties under common control) regulated 
as CMRS (see 47 CFR 20.9) shall have an attributable interest in a total 
of more than 55 MHz of licensed broadband PCS, cellular, and SMR 
spectrum regulated as CMRS with significant overlap in any geographic 
area.
    (b) SMR spectrum. To calculate the amount of attributable SMR 
spectrum for purposes of paragraph (a) of this section, an entity must 
count all 800 MHz and 900 MHz channels located at any SMR base station 
inside the geographic area (MTA or BTA) where there is significant 
overlap. All 800 MHz channels located on at least one of those 
identified base stations count as 50 kHz (25 kHz paired), and all 900 
MHz channels located on at least one of those identified base stations 
count as 25 kHz (12.5 kHz paired); provided that any discrete 800 or 900 
MHz channel shall be counted only once per licensee within the 
geographic area, even if the licensee in question utilizes the same 
channel at more than one location within the relevant geographic area. 
No more than 10 MHz of SMR spectrum in the 800 and 900 MHz SMR services 
will be attributed to an entity when determining compliance with the 
cap.
    (c) Significant overlap. (1) For purposes of paragraph (a) of this 
section, significant overlap of a PCS licensed service area and CGSA(s) 
(as defined in Sec.  22.911 of this chapter) or SMR service area(s) 
occurs when at least 10 percent of the population of the PCS licensed 
service area for the counties contained therein, as determined by the 
latest available decennial census figures as complied by the Bureau of 
the Census, is within the CGSA(s) and/or SMR service area(s).
    (2) The Commission shall presume that an SMR service area covers 
less

[[Page 9]]

than 10 percent of the population of a PCS service area if none of the 
base stations of the SMR licensee are located within the PCS service 
area. For an SMR licensee's base stations that are located within a PCS 
service area, the channels licensed at those sites will be presumed to 
cover 10 percent of the population of the PCS service area, unless the 
licensee shows that its protected service contour for all of its base 
stations covers less than 10 percent of the population of the PCS 
service area.
    (d) Ownership attribution. For purposes of paragraph (a) of this 
section, ownership and other interests in broadband PCS licensees, 
cellular licensees, or SMR licensees will be attributed to their holders 
pursuant to the following criteria:
    (1) Controlling interest shall be attributable. Controlling interest 
means majority voting equity ownership, any general partnership 
interest, or any means of actual working control (including negative 
control) over the operation of the licensee, in whatever manner 
exercised.
    (2) Partnership and other ownership interests and any stock interest 
amounting to 20 percent or more of the equity, or outstanding stock, or 
outstanding voting stock of a broadband PCS, cellular or SMR licensee 
shall be attributed, except that ownership will not be attributed unless 
the partnership and other ownership interests and any stock interest 
amount to at least 40 percent of the equity, or outstanding stock, or 
outstanding voting stock of a broadband PCS, cellular or SMR licensee if 
the ownership interest is held by a small business or a rural telephone 
company, as these terms are defined in Sec.  1.2110 of this chapter or 
other related provisions of the Commission's rules, or if the ownership 
interest is held by an entity with a non-controlling equity interest in 
a broadband PCS licensee or applicant that is a small business.
    (3) Investment companies, as defined in 15 U.S.C. 80a-3, insurance 
companies and banks holding stock through their trust departments in 
trust accounts will be considered to have an attributable interest only 
if they hold 40 percent or more of the outstanding voting stock of a 
corporate broadband PCS, cellular or SMR licensee, or if any of the 
officers or directors of the broadband PCS, cellular or SMR licensee are 
representatives of the investment company, insurance company or bank 
concerned. Holdings by a bank or insurance company will be aggregated if 
the bank or insurance company has any right to determine how the stock 
will be voted. Holdings by investment companies will be aggregated if 
under common management.
    (4) Non-voting stock shall be attributed as an interest in the 
issuing entity if in excess of the amounts set forth in paragraph (d)(2) 
of this section.
    (5) Debt and instruments such as warrants, convertible debentures, 
options, or other interests (except non-voting stock) with rights of 
conversion to voting interests shall not be attributed unless and until 
converted, except that this provision does not apply in determining 
whether an entity is a small business, a rural telephone company, or a 
business owned by minorities and/or women, as these terms are defined in 
Sec.  1.2110 of this chapter or other related provisions of the 
Commission's rules.
    (6) Limited partnership interests shall be attributed to limited 
partners and shall be calculated according to both the percentage of 
equity paid in and the percentage of distribution of profits and losses.
    (7) Officers and directors of a broadband PCS licensee or applicant, 
cellular licensee, or SMR licensee shall be considered to have an 
attributable interest in the entity with which they are so associated. 
The officers and directors of an entity that controls a broadband PCS 
licensee or applicant, a cellular licensee, or an SMR licensee shall be 
considered to have an attributable interest in the broadband PCS 
licensee or applicant, cellular licensee, or SMR licensee.
    (8) Ownership interests that are held indirectly by any party 
through one or more intervening corporations will be determined by 
successive multiplication of the ownership percentages for each link in 
the vertical ownership chain and application of the relevant attribution 
benchmark to the resulting product, except that if the ownership 
percentage for an interest in any link

[[Page 10]]

in the chain exceeds 50 percent or represents actual control, it shall 
be treated as if it were a 100 percent interest. (For example, if A owns 
20% of B, and B owns 40% of licensee C, then A's interest in licensee C 
would be 8%. If A owns 20% of B, and B owns 51% of licensee C, then A's 
interest in licensee C would be 20% because B's ownership of C exceeds 
50%.)
    (9) Any person who manages the operations of a broadband PCS, 
cellular, or SMR licensee pursuant to a management agreement shall be 
considered to have an attributable interest in such licensee if such 
person, or its affiliate, has authority to make decisions or otherwise 
engage in practices or activities that determine, or significantly 
influence,
    (i) The nature or types of services offered by such licensee;
    (ii) The terms upon which such services are offered; or
    (iii) The prices charged for such services.
    (10) Any licensee or its affiliate who enters into a joint marketing 
arrangements with a broadband PCS, cellular, or SMR licensee, or its 
affiliate shall be considered to have an attributable interest, if such 
licensee, or its affiliate, has authority to make decisions or otherwise 
engage in practices or activities that determine, or significantly 
influence,
    (i) The nature or types of services offered by such licensee;
    (ii) The terms upon which such services are offered; or
    (iii) The prices charged for such services.
    (e) Divestiture. (1) Divestiture of interests as a result of a 
transfer of control or assignment of authorization must occur prior to 
consummating the transfer or assignment, except that a licensee that 
meets the requirements set forth in paragraph (e)(2) of this section 
shall have 90 days from final grant to come into compliance with the 
spectrum aggregation limit.
    (2) An applicant with:
    (i) Controlling or attributable ownership interests in broadband 
PCS, cellular, and/or SMR licenses where the geographic license areas 
cover 20 percent or less of the applicant's service area population;
    (ii) Attributable interests in broadband PCS, cellular, and/or SMR 
licenses solely due to management agreements or joint marketing 
agreements; or
    (iii) Non-controlling attributable interests in broadband PCS, 
cellular, and/or SMR licenses, regardless of the degree to which the 
geographic license areas cover the applicant's service area population, 
shall be eligible to have its application granted subject to a condition 
that the licensee shall come into compliance with the spectrum 
limitation set out in paragraph (a) within ninety (90) days after final 
grant. For purposes of this paragraph, a ``non-controlling attributable 
interest'' is one in which the holder has less than a fifty (50) percent 
voting interest and there is an unaffiliated single holder of a fifty 
(50) percent or greater voting interest.
    (3) The applicant for a license that, if granted, would exceed the 
spectrum aggregation limitation in paragraph (a) of this section shall 
certify on its application that it and all parties to the application 
will come into compliance with this limitation. If such an applicant is 
a successful bidder in an auction, it must submit with its long-form 
application a signed statement describing its efforts to date and future 
plans to come into compliance with the spectrum aggregation limitation. 
A similar statement must also be included with any application for 
assignment of licenses or transfer of control that, if granted, would 
exceed the spectrum aggregation limit.
    (4)(i) Parties holding controlling interests in broadband PCS, 
cellular, and/or SMR licensees that conflict with the attribution 
threshold or geographic overlap limitations set forth in this section 
will be considered to have come into compliance if they have submitted 
to the Commission an application for assignment of license or transfer 
of control of the conflicting licensee (see Sec.  1.948 of this chapter; 
see also Sec.  24.839 of this chapter (PCS)) by which, if granted, such 
parties no longer would have an attributable interest in the conflicting 
license. Divestiture may be to an interim trustee if a buyer has not 
been secured in the required period of time, as long as the applicant 
has no interest in or control of the trustee,

[[Page 11]]

and the trustee may dispose of the license as it sees fit. Where parties 
to broadband PCS, cellular, or SMR applications hold less than 
controlling (but still attributable) interests in broadband PCS, 
cellular, or SMR licensee(s), they shall submit a certification that the 
applicant and all parties to the application have come into compliance 
with the limitations on spectrum aggregation set forth in this section.
    (ii) Applicants that meet the requirements of paragraph (e)(2) of 
this section must tender to the Commission within ninety (90) days of 
final grant of the initial license, such an assignment or transfer 
application or, in the case of less than controlling (but still 
attributable) interests, a written certification that the applicant and 
all parties to the application have come into compliance with the 
limitations on spectrum aggregation set forth in this section. If no 
such transfer or assignment application or certification is tendered to 
the Commission within ninety (90) days of final grant of the initial 
license, the Commission may consider the certification and the 
divestiture statement to be material, bad faith misrepresentations and 
shall invoke the condition on the initial license or the assignment or 
transfer, cancelling or rescinding it automatically, shall retain all 
monies paid to the Commission, and, based on the facts presented, shall 
take any other action it may deem appropriate.
    (f) Sunset. This rule section shall cease to be effective January 1, 
2003.

    Note 1 to Sec.  20.6: For purposes of the ownership attribution 
limit, all ownership interests in operations that serve at least 10 
percent of the population of the PCS service area should be included in 
determining the extent of a PCS applicant's cellular or SMR ownership.
    Note 2 to Sec.  20.6: When a party owns an attributable interest in 
more than one cellular or SMR system that overlaps a PCS service area, 
the total population in the overlap area will apply on a cumulative 
basis.
    Note 3 to Sec.  20.6: Waivers of Sec.  20.6(d) may be granted upon 
an affirmative showing:
    (1) That the interest holder has less than a 50 percent voting 
interest in the licensee and there is an unaffiliated single holder of a 
50 percent or greater voting interest;
    (2) That the interest holder is not likely to affect the local 
market in an anticompetitive manner;
    (3) That the interest holder is not involved in the operations of 
the licensee and does not have the ability to influence the licensee on 
a regular basis; and
    (4) That grant of a waiver is in the public interest because the 
benefits to the public of common ownership outweigh any potential 
anticompetitive harm to the market.

mutually agree otherwise.
    (c) Local exchange carriers and commercial mobile radio service 
providers shall also comply with applicable provisions of part 51 of 
this chapter.
    (d) Local exchange carriers may not impose compensation obligations 
for traffic not subject to access charges upon commercial mobile radio 
service providers pursuant to tariffs.
    (e) An incumbent local exchange carrier may request interconnection 
from a commercial mobile radio service provider and invoke the 
negotiation and arbitration procedures contained in section 252 of the 
Act. A commercial mobile radio service provider receiving

[[Page 12]]

a request for interconnection must negotiate in good faith and must, if 
requested, submit to arbitration by the state commission.

Sec.  20.12  Resale and roaming.

    (a)(1) Scope of manual roaming and resale. Paragraph (c) of this 
section is applicable to providers of Broadband Personal Communications 
Services (part 24, subpart E of this chapter), Cellular Radio Telephone 
Service (part 22, subpart H of this chapter), Specialized Mobile Radio 
Services in the 800 MHz and 900 MHz bands (included in part 90, subpart 
S of this chapter), and 900 MHz Broadband Service (included in part 27, 
subpart P of this chapter) if such providers offer real-time, two-way 
switched voice or data service that is interconnected with the public 
switched network and utilizes an in-network switching facility that 
enables the provider to re-use frequencies and accomplish seamless hand-
offs of subscriber calls. The scope of paragraph (b) of this section, 
concerning the resale rule, is further limited so as to exclude from the 
requirements of that paragraph those Broadband Personal Communications 
Services C, D, E, and F block licensees that do not own and control and 
are not owned and controlled by firms also holding cellular A or B block 
licenses.
    (2) Scope of automatic roaming. Paragraph (d) of this section is 
applicable to CMRS carriers if such carriers offer real-time, two-way 
switched voice or data service that is interconnected with the public 
switched network and utilizes an in-network switching facility that 
enables the carrier to re-use frequencies and accomplish seamless hand-
offs of subscriber calls. Paragraph (d) of this section is also 
applicable to the provision of push-to-talk and text-messaging service 
by CMRS carriers.
    (3) Scope of offering roaming arrangements for commercial mobile 
data services. Paragraph (e) of this section is applicable to all 
facilities-based providers of commercial mobile data services.
    (b) Resale. The resale rule is applicable as follows:
    (1) Each carrier subject to paragraph (b) of this section shall not 
restrict the resale of its services, unless the carrier demonstrates 
that the restriction is reasonable.
    (2) The resale requirement shall not apply to customer premises 
equipment, whether or not it is bundled with services subject to the 
resale requirement in this paragraph.
    (3) This paragraph shall cease to be effective five years after the 
last group of initial licenses for broadband PCS spectrum in the 1850-
1910 and the 1930-1990 MHz bands is awarded; i.e., at the close of 
November 24, 2002.
    (c) Manual roaming. Each carrier subject to paragraph (a)(1) of this 
section must provide mobile radio service upon request to all 
subscribers in good standing to the services of any carrier subject to 
paragraph (a)(1) of this section, including roamers, while such 
subscribers are located within any portion of the licensee's licensed 
service area where facilities have been constructed and service to 
subscribers has commenced, if such subscribers are using mobile 
equipment that is technically compatible with the licensee's base 
stations.
    (d) Automatic roaming. Upon a reasonable request, it shall be the 
duty of each host carrier subject to paragraph (a)(2) of this section to 
provide automatic roaming to any technologically compatible, facilities-
based CMRS carrier on reasonable and not unreasonably discriminatory 
terms and conditions, pursuant to Sections 201 and 202 of the 
Communications Act, 47 U.S.C. 201 and 202. The Commission shall presume 
that a request by a technologically compatible CMRS carrier for 
automatic roaming is reasonable pursuant to Sections 201 and 202 of the 
Communications Act, 47 U.S.C. 201 and 202. This presumption may be 
rebutted on a case by case basis. The Commission will resolve automatic 
roaming disputes on a case-by-case basis, taking into consideration the 
totality of the circumstances presented in each case.
    (e) Offering roaming arrangements for commercial mobile data 
services. (1) A facilities-based provider of commercial mobile data 
services is required to offer roaming arrangements to other

[[Page 13]]

such providers on commercially reasonable terms and conditions, subject 
to the following limitations:
    (i) Providers may negotiate the terms of their roaming arrangements 
on an individualized basis;
    (ii) It is reasonable for a provider not to offer a data roaming 
arrangement to a requesting provider that is not technologically 
compatible;
    (iii) It is reasonable for a provider not to offer a data roaming 
arrangement where it is not technically feasible to provide roaming for 
the particular data service for which roaming is requested and any 
changes to the host provider's network necessary to accommodate roaming 
for such data service are not economically reasonable;
    (iv) It is reasonable for a provider to condition the effectiveness 
of a roaming arrangement on the requesting provider's provision of 
mobile data service to its own subscribers using a generation of 
wireless technology comparable to the technology on which the requesting 
provider seeks to roam.
    (2) A party alleging a violation of this section may file a formal 
or informal complaint pursuant to the procedures in Sec. Sec.  1.716 
through 1.718, 1.720, 1.721, and 1.723 through 1.735 of this chapter, 
which sections are incorporated herein. For purposes of Sec.  20.12(e), 
references to a ``carrier'' or ``common carrier'' in the formal and 
informal complaint procedures incorporated herein will mean a provider 
of commercial mobile data services. The Commission will resolve such 
disputes on a case-by-case basis, taking into consideration the totality 
of the circumstances presented in each case. The remedy of damages shall 
not be available in connection with any complaint alleging a violation 
of this section. Whether the appropriate procedural vehicle for a 
dispute is a complaint under this paragraph or a petition for 
declaratory ruling under Sec.  1.2 of this chapter may vary depending on 
the circumstances of each case.

Sec.  20.13  State petitions for authority to regulate rates.

    (a) States may petition for authority to regulate the intrastate 
rates of any commercial mobile radio service. The petition must include 
the following:
    (1) Demonstrative evidence that market conditions in the state for 
commercial mobile radio services do not adequately protect subscribers 
to such services from unjust and unreasonable rates or rates that are 
unjustly or unreasonably discriminatory. Alternatively, a state's 
petition may include demonstrative evidence showing that market 
conditions for commercial mobile radio services do not protect 
subscribers adequately from unjust and unreasonable rates, or rates that 
are unjustly or unreasonably discriminatory, and that a substantial 
portion of the commercial mobile radio service subscribers in the state 
or a specified geographic area have no alternative means of obtaining 
basic telephone service. This showing may include evidence of the range 
of basic telephone service alternatives available to consumers in the 
state.
    (2) The following is a non-exhaustive list of examples of the types 
of evidence, information, and analysis that may be considered pertinent 
to determine market conditions and consumer protection by the Commission 
in reviewing any petition filed by a state under this section:
    (i) The number of commercial mobile radio service providers in the 
state, the types of services offered by commercial mobile radio service 
providers in the state, and the period of time that these providers have 
offered service in the state;
    (ii) The number of customers of each commercial mobile radio service 
provider in the state; trends in each provider's customer base during 
the most recent annual period or other data covering another reasonable 
period if annual data is unavailable; and annual revenues and rates of 
return for each commercial mobile radio service provider;
    (iii) Rate information for each commercial mobile radio service 
provider, including trends in each provider's rates during the most 
recent annual period or other data covering another

[[Page 14]]

reasonable period if annual data is unavailable;
    (iv) An assessment of the extent to which services offered by the 
commercial mobile radio service providers the state proposes to regulate 
are substitutable for services offered by other carriers in the state;
    (v) Opportunities for new providers to enter into the provision of 
competing services, and an analysis of any barriers to such entry;
    (vi) Specific allegations of fact (supported by affidavit of person 
with personal knowledge) regarding anti-competitive or discriminatory 
practices or behavior by commercial mobile radio service providers in 
the state;
    (vii) Evidence, information, and analysis demonstrating with 
particularity instances of systematic unjust and unreasonable rates, or 
rates that are unjust or unreasonably discriminatory, imposed upon 
commercial mobile radio service subscribers. Such evidence should 
include an examination of the relationship between rates and costs. 
Additionally, evidence of a pattern of such rates, that demonstrates the 
inability of the commercial mobile radio service marketplace in the 
state to produce reasonable rates through competitive forces will be 
considered especially probative; and
    (viii) Information regarding customer satisfaction or 
dissatisfaction with services offered by commercial mobile radio service 
providers, including statistics and other information about complaints 
filed with the state regulatory commission.
    (3) Petitions must include a certification that the state agency 
filing the petition is the duly authorized state agency responsible for 
the regulation of telecommunication services provided in the state.
    (4) Petitions must identify and describe in detail the rules the 
state proposes to establish if the petition is granted.
    (5) States have the burden of proof. Interested parties may file 
comments in support or in opposition to the petition within 30 days 
after public notice of the filing of a petition by a state under this 
section. Any interested party may file a reply within 15 days after the 
expiration of the filing period for comments. No additional pleadings 
may be filed. Except for Sec.  1.45 of this chapter, practice and 
procedure rules contained in Sec. Sec.  1.42-1.52 of this chapter shall 
apply. The provisions of Sec. Sec.  1.771-1.773 of this chapter do not 
apply.
    (6) The Commission shall act upon any petition filed by a state 
under this paragraph not later than the end of the nine-month period 
after the filing of the petition.
    (7) If the Commission grants the petition, it shall authorize the 
state to regulate rates for commercial mobile radio services in the 
state during a reasonable period of time, as specified by the

Sec.  20.20  Conditions applicable to provision of CMRS service by 
incumbent Local Exchange Carriers.

    (a) Separate affiliate. An incumbent LEC providing in-region 
broadband CMRS shall provide such services through an affiliate that 
satisfies the following requirements:
    (1) The affiliate shall maintain separate books of account from its 
affiliated incumbent LEC. Nothing in this section requires the affiliate 
to maintain separate books of account that comply with part 32 of this 
chapter;
    (2) The affiliate shall not jointly own transmission or switching 
facilities with its affiliated incumbent LEC that the affiliated 
incumbent LEC uses for the provision of local exchange service in the 
same in-region market. Nothing in this section prohibits the affiliate 
from sharing personnel or other resources or assets with its affiliated 
incumbent LEC; and
    (3) The affiliate shall acquire any services from its affiliated 
incumbent LEC for which the affiliated incumbent LEC is required to file 
a tariff at tariffed rates, terms, and conditions. Other transactions 
between the affiliate and the incumbent LEC for services that are not 
acquired pursuant to tariff must be reduced to writing and must be made 
on a compensatory, arm's length basis. All transactions between the 
incumbent LEC and the affiliate are subject to part 32 of this chapter, 
including the affiliate transaction rules. Nothing in this section shall 
prohibit the affiliate from acquiring any unbundled network elements or 
exchange services for the provision of a telecommunications service from 
its affiliated incumbent LEC, subject to the same terms and conditions 
as provided in an agreement approved under section 252 of the 
Communications Act of 1934, as amended.
    (b) Independence. The affiliate required in paragraph (a) of this 
section shall be a separate legal entity from its affiliated incumbent 
LEC. The affiliate may be staffed by personnel of its affiliated 
incumbent LEC, housed in existing offices of its affiliated incumbent 
LEC, and use its affiliated incumbent LEC's marketing and other 
services, subject to paragraphs (a)(3) and (c) of this section.
    (c) Joint marketing. Joint marketing of local exchange and exchange 
access service and CMRS services by an incumbent LEC shall be subject to 
part 32 of this chapter. In addition, such agreements between the 
affiliate and the incumbent LEC must be reduced to writing and made 
available for public inspection upon request at the principle place of 
business of the affiliate and the incumbent LEC. The documentation must 
include a certification statement identical to the certification

[[Page 23]]

statement currently required to be included with all Automated Reporting 
and Management Information Systems (ARMIS) reports. The affiliate must 
also provide a detailed written description of the terms and conditions 
of the transaction on the Internet within 10 days of the transaction 
through the affiliate's home page.
    (d) Exceptions--(1) Rural telephone companies. Rural telephone 
companies are exempted from the requirements set forth in paragraphs 
(a), (b) and (c) of this section. A competing telecommunications 
carrier, interconnected with the rural telephone company, however, may 
petition the FCC to remove the exemption, or the FCC may do so on its 
own motion, where the rural telephone company has engaged in 
anticompetitive conduct.
    (2) Incumbent LECs with fewer than 2 percent of subscriber lines. 
Incumbent LECs with fewer than 2 percent of the nation's subscriber 
lines installed in the aggregate nationwide may petition the FCC for 
suspension or modification of the requirements set forth in paragraphs 
(a), (b) and (c) of this section. The FCC will grant such a petition 
where the incumbent LEC demonstrates that suspension or modification of 
the separate affiliate requirement is
    (i) Necessary to avoid a significant adverse economic impact on 
users of telecommunications services generally or to avoid a requirement 
that would be unduly economically burdensome, and
    (ii) Consistent with the public interest, convenience, and 
necessity.
    (e) Definitions. Terms used in this section have the following 
meanings:
    Affiliate. ``Affiliate'' means a person that (directly or 
indirectly) owns or controls, is owned or controlled by, or is under 
common ownership with, another person. For purposes of this section, the 
term ``own'' means to own an equity interest (or the equivalent thereof) 
of more than 10 percent.
    Broadband Commercial Mobile Radio Service (Broadband CMRS). For the 
purposes of this section, ``broadband CMRS'' means Cellular 
Radiotelephone Service (part 22, subpart H of this chapter), Specialized 
Mobile Radio (part 90, subpart S of this chapter), and broadband 
Personal Communications Services (part 24, subpart E of this chapter).
    Incumbent Local Exchange Carrier (Incumbent LEC). ``Incumbent LEC'' 
has the same meaning as that term is defined in Sec.  51.5 of this 
chapter.
    In-region. For the purposes of this section, an incumbent LEC's 
broadband CMRS service is considered ``in-region'' when 10 percent or 
more of the population covered by the CMRS affiliate's authorized 
service area, as determined by the 1990 census figures, is within the 
affiliated incumbent LEC's wireline service area.
    Rural Telephone Company. ``Rural Telephone Company'' has the same 
meaning as that term is defined in Sec.  51.5 of this chapter.
    (f) Sunset. This section will no longer be effective after January 
1, 2002.

    (7) Interference Avoidance for Wireless Subsystems. Consumer Signal 
Boosters using unlicensed (part 15 of this chapter) or other frequency 
bands for wireless transmissions between donor and server subsystems for 
their internal operations must employ interference avoidance methods to 
prevent interference transmitted into authorized CMRS spectrum bands.
    (8) Wideband Consumer Signal Boosters. A Wideband Consumer Signal 
Booster will meet the Consumer Signal Booster Network Protection 
Standard if it complies with paragraphs (e)(1) through (e)(7) of this 
section and the following:

terms of RMS equivalent voltage.
    (E) Out of Band Emission Limits. Booster out of band emissions 
(OOBE) shall be at least 6 dB below the FCC's mobile emission limits for 
the supported bands of operation. Compliance to OOBE limits will utilize 
high peak-to-average CMRS signal types.
    (F) Intermodulation Limits. The transmitted intermodulation products 
of a consumer booster at its uplink and downlink ports shall not exceed

booster is in use.
    (A) Anti-Oscillation. Consumer boosters must be able to detect and 
mitigate (i.e., by automatic gain reduction or shut down), any 
oscillations in uplink and downlink bands. Oscillation detection and 
mitigation must occur automatically within 0.3 seconds in the uplink 
band and within 1 second in the downlink band. In cases where 
oscillation is detected, the booster must continue mitigation for at 
least one minute before restarting. After five such restarts, the 
booster must not resume operation until manually reset.
    (B) Gain Control. Consumer boosters must have automatic limiting 
control to protect against excessive input signals that would cause 
output power and emissions in excess of that authorized by the 
Commission.
    (C) Interference Avoidance for Wireless Subsystems. Consumer 
boosters using unlicensed (part 15) or other frequency bands for 
wireless transmissions between donor and server subsystems for its 
internal operations must employ interference avoidance methods to 
prevent interference transmitted into authorized CMRS spectrum bands and 
must meet applicable limits for radiofrequency exposure.

RSSI is expressed in negative dB units relative to 1 mW.
    (ii) Boosters with MSCL less than 40 dB, shall reduce the Noise 
output in (A) by 40 dB-MSCL, where MSCL is the minimum coupling loss in 
dB between the wireless device and booster's server port. MSCL must be 
calculated or measured for each band of operation and provided in 
compliance test reports.
    (2)(i) Fixed booster maximum downlink noise power shall not exceed -
102.5 dBm/MHz + 20 Log10 (Frequency), where Frequency is the

    (ii) In order of preference, BSCL is determined as follows: 
determine path loss between the base station and the booster; such 
measurement shall be based on measuring the received forward pilot/
control channel power at the booster and reading the pilot/control 
channel transmit power from the base station as defined in the system 
information messages sent by the base station; estimate BSCL by assuming 
that the base station is transmitting at a level of + 25 dBm per channel 
(assume a small, lightly loaded cell) and measuring the total received 
signal power level within the channel in dBm (RPCH) received at the 
booster input port. BSCL is then calculated as 25-RPCH; or assume that

mitigate (i.e., by automatic gain reduction or shut down), any 
oscillations in uplink and downlink bands. Oscillation detection and 
mitigation must occur automatically within 0.3 seconds in the uplink 
band and within 1 second in the downlink band. In cases where 
oscillation is detected, the booster must continue mitigation for at 
least one

[[Page 29]]

minute before restarting. After five such restarts, the booster must not 
resume operation until manually reset.
    (B) Gain Control. Consumer boosters must have automatic limiting 
control to protect against excessive input signals that would cause 
output power and emissions in excess of that authorized by the 
Commission.
    (C) Interference Avoidance for Wireless Subsystems. Consumer 
boosters using unlicensed (part 15) or other frequency bands for 
wireless transmissions between donor and server subsystems for its 
internal operations must employ interference avoidance methods to 
prevent interference transmitted into authorized CMRS spectrum bands.
    (10) Equivalent Protections. Consumer Signal Boosters which do not 
meet the technical specifications enumerated in paragraphs (e)(1) 
through (e)(9) of this section may also meet the Network Protection 
Standard if they provide equivalent protections as determined by the 
Wireless Telecommunications Bureau.
    (f) Signal booster labeling requirements. (1) Signal booster 
manufacturers, distributors, and retailers must ensure that all signal 
boosters marketed on or after March 1, 2014 include the following 
advisories:
    (i) In on-line, point-of-sale marketing materials,
    (ii) In any print or on-line owner's manual and installation 
instructions,
    (iii) On the outside packaging of the device, and
    (iv) On a label affixed to the device:
    (A) For Consumer Signal Boosters:
    (1) This is a CONSUMER device.

    BEFORE USE, you MUST REGISTER THIS DEVICE with your wireless 
provider and have your provider's consent. Most wireless providers 
consent to the use of signal boosters. Some providers may not consent to 
the use of this device on their network. If you are unsure, contact your 
provider.
    You MUST operate this device with approved antennas and cables as 
specified by the manufacturer. Antennas MUST be installed at least 20 cm 
(8 inches) from any person.
    You MUST cease operating this device immediately if requested by the 
FCC or a licensed wireless service provider.
    WARNING. E911 location information may not be provided or may be 
inaccurate for calls served by using this device.
    (2) The label for Consumer Signal Boosters certified for fixed 
indoor operation also must include the following language:
    This device may be operated ONLY in a fixed location for in-building 
use.

    (B) For Industrial Signal Boosters:

    WARNING. This is NOT a CONSUMER device. It is designed for 
installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an 
FCC LICENSE or express consent of an FCC Licensee to operate this 
device. Unauthorized use may result in significant forfeiture penalties, 
including penalties in excess of $100,000 for each continuing violation.

    (2) A Consumer Signal Booster label may contain an acknowledgement 
that particular provider(s) have given their consent for all consumers 
to use the device. Such an acknowledgement would be inserted prior to, 
``Some wireless providers may not consent to the use of this device on 
their network. If you are unsure, contact your provider.'' The remaining 
language of the advisory shall remain the same.
    (g) Marketing and sale of signal boosters. Except as provided in 
Sec.  2.803 of this chapter, no person, manufacturer, distributor, or 
retailer may market (as defined in Sec.  2.803 of this chapter) any 
Consumer Signal Booster that does not comply with the requirements of 
this section to any person in the United States or to any person 
intending to operate the Consumer Signal Booster within the United 
States. Wideband Consumer Signal Boosters may only be sold to members of 
the general public for their personal use.
    (h) Registration. Each licensee consenting to the operation of a 
Consumer Signal Booster must establish a free registration mechanism for 
subscribers and register all Consumer Signal Boosters to which it 
consents. A licensee must establish a registration mechanism by the 
later of March 1, 2014 or within 90 days of consenting to the operation 
of a Consumer Signal Booster. At a minimum, a licensee must collect:
    (1) The name of the Consumer Signal Booster owner and/or operator, 
if different individuals;
    (2) The make, model, and serial number of the device;
    (3) The location of the device; and

[[Page 30]]

    (4) The date of initial operation. Licensee consent is voluntary and 
may be withdrawn at the licensee's discretion.

83 FR 17090, Apr. 18, 2018]



Sec.  20.22  Rules governing mobile spectrum holdings.

    (a) Applicants for mobile wireless licenses for commercial use, for 
assignment or transfer of control of such licenses, or for long-term de 
facto transfer leasing arrangements as defined in Sec.  1.9003 of this 
chapter and long-term spectrum manager leasing arrangements as 
identified in Sec.  1.9020(e)(1)(ii) must demonstrate that the public 
interest, convenience, and necessity will be served thereby. The 
Commission will evaluate any such license application consistent with 
the policies set forth in Policies Regarding Mobile Spectrum Holdings, 
Report and Order, FCC 14-63, WT Docket No. 12-269, adopted May 15, 2014.
    (b) Attribution of interests. (1) The following criteria will apply 
to attribute partial ownership and other interests in spectrum holdings 
for purposes of:
    (i) Applying a mobile spectrum holding limit to the licensing of 
spectrum through competitive bidding; and
    (ii) Applying the initial spectrum screen to secondary market 
transactions.
    (2) Controlling interests shall be attributable. Controlling 
interest means majority voting equity ownership, any general partnership 
interest, or any means of actual working control (including negative 
control) over the operation of the licensee, in whatever manner 
exercised.
    (3) Non-controlling interests of 10 percent or more in spectrum 
shall be attributable. Interests of less than 10 percent in spectrum 
shall be attributable if such interest confers de facto control, 
including but not limited to partnership and other ownership interests 
and any stock interest in a licensee.
    (4) The following interests in spectrum shall also be attributable 
to holders:
    (i) Officers and directors of a licensee shall be considered to have 
an attributable interest in the entity with which they are so 
associated. The officers and directors of an entity that controls a 
licensee or applicant shall be considered to have an attributable 
interest in the licensee.
    (ii) Ownership interests that are held indirectly by any party 
through one or more intervening corporations will be determined by 
successive multiplication of the ownership percentages for each link in 
the vertical ownership chain and application of the relevant attribution 
benchmark to the resulting product, except that if the ownership 
percentage for an interest in any link in the chain exceeds 50 percent 
or represents actual control, it shall be treated as if it were a 100 
percent interest. (For example, if A owns 20% of B, and B owns 40% of 
licensee C, then A's interest in licensee C would be 8%. If A owns 20% 
of B, and B owns 51% of licensee C, then A's interest in licensee C 
would be 20% because B's ownership of C exceeds 50%).
    (iii) Any person who manages the operations of a licensee pursuant 
to a management agreement shall be considered to have an attributable 
interest in such licensee if such person, or its affiliate, has 
authority to make decisions or otherwise engage in practices or 
activities that determine, or significantly influence, the nature or 
types of services offered by such licensee, the terms upon which such 
services are offered, or the prices charged for such services.
    (iv) Any licensee or its affiliate who enters into a joint marketing 
arrangement with another licensee or its affiliate shall be considered 
to have an attributable interest in the other licensee's holdings if it 
has authority to make decisions or otherwise engage in practices or 
activities that determine or significantly influence the nature or types 
of services offered by the other licensee, the terms upon which such 
services are offered, or the prices charged for such services.
    (v) Limited partnership interests shall be attributed to limited 
partners and shall be calculated according to both the percentage of 
equity paid in and the percentage of distribution of profits and losses.
    (vi) Debt and instruments such as warrants, convertible debentures, 
options, or other interests (except non-

[[Page 31]]

voting stock) with rights of conversion to voting interests shall not be 
attributed unless and until converted or unless the Commission 
determines that these interests confer de facto control.
    (5) The following interests shall be attributable to holders, except 
to lessees and sublessees for the purpose of qualifying to bid on 
reserved licenses offered in the Incentive Auction, discussed in 
paragraph (c) of this section, on the basis of status as a non-
nationwide provider:
    (i) Long-term de facto transfer leasing arrangements as defined in 
Sec.  1.9003 of this chapter and long-term spectrum manager leasing 
arrangements as identified in Sec.  1.9020(e)(1)(ii) that enable 
commercial use shall be attributable to lessees, lessors, sublessees, 
and sublessors for purposes of this section.
    (ii) [Reserved]
    (c) 600 MHz Band holdings. (1) The Commission will reserve licenses 
for up to 30 megahertz of the 600 MHz Band, offered in the Incentive 
Auction authorized by Congress pursuant to 47 U.S.C. 309(j)(8)(G), for 
otherwise qualified bidders who do not hold an attributable interest in 
45 megahertz or more of the total 134 megahertz of below-1-GHz spectrum 
which consists of the cellular (50 megahertz), the 700 MHz (70 
megahertz), and the SMR (14 megahertz) spectrum in a Partial Economic 
Area (PEA), as calculated on a county by county population-weighted 
basis, utilizing 2010 U.S. Census data. The amount of reserved and 
unreserved 600 MHz Band licenses will be determined based on the market-
based spectrum reserve set forth in Policies Regarding Mobile Spectrum 
Holdings, Report and Order, FCC 14-63, WT Docket No. 12-269, adopted May 
15, 2014, as well as subsequent Public Notices. Nothing in this 
paragraph will limit, or may be construed to limit, an otherwise 
qualified bidder that is a non-nationwide provider of mobile wireless 
services from bidding on any reserved or unreserved license offered in 
the Incentive Auction.
    (2) For a period of six years, after initial licensing, no 600 MHz 
Band license, regardless of whether it is reserved or unreserved, may be 
transferred, assigned, partitioned, disaggregated, or long term leased 
to any entity that, after consummation of the transfer, assignment, or 
leased on a long term basis, would hold an attributable interest in one-
third or more of the total suitable and available below-1-GHz spectrum 
as calculated on a county by county population-weighted basis in the 
relevant license area, utilizing 2010 U.S. Census data.
    (3) For a period of six years, after initial licensing, no 600 MHz 
Band reserved license may be transferred, assigned, partitioned, 
disaggregated, or leased on a long term basis to an entity that was not 
qualified to bid on that reserved spectrum license under paragraph 
(c)(1) of this section at the time of the Incentive Auction short-form 
application deadline.

[79 FR 40002, July 11, 2014, as amended at 80 FR 61970, Oct. 14, 2015]



Sec.  20.23  Contraband wireless devices in correctional facilities.

    (a) Good faith negotiations. CMRS licensees must negotiate in good 
faith with entities seeking to deploy a Contraband Interdiction System 
(CIS) in a correctional facility. Upon receipt of a good faith request 
by an entity seeking to deploy a CIS in a correctional facility, a CMRS 
licensee must negotiate toward a lease agreement. If, after a 45 day 
period, there is no agreement, CIS providers seeking Special Temporary 
Authority (STA) to operate in the absence of CMRS licensee consent may 
file a request for STA with the Wireless Telecommunications Bureau 
(WTB), accompanied by evidence demonstrating its good faith, and the 
unreasonableness of the CMRS licensee's actions, in negotiating an 
agreement. The request must be served on the CMRS licensee no later than 
the filing of the STA request, and the CMRS licensee may file a response 
with WTB, with a copy served on the CIS provider at that time, within 10 
days of the filing of the STA request. If WTB determines that the CIS 
provider has negotiated in good faith, yet the CMRS licensee has not 
negotiated in good faith, WTB may issue STA to the entity seeking to 
deploy the CIS, notwithstanding lack of accompanying CMRS licensee 
consent.

[[Page 32]]

    (b) Contraband Interdiction System (CIS) authorization process. The 
provisions in this section apply to any person seeking certification of 
a CIS authorized for use in the submission of qualifying disabling 
requests, whether operating a system that requires a license and is 
regulated as CMRS or private mobile radio service (PMRS), or operating a 
passive system that does not require a license. The Wireless 
Telecommunications Bureau (Bureau) will establish, via public notice, 
the form and procedure for: CIS operators to file CIS certification 
applications, self-certifications, and periodic re-certification; CIS 
operators to serve on wireless providers notice of testing and copies of 
self-certification; and wireless providers to file objections to self-
certifications, including required service on CIS operators and DCFOs.
    (1) Application requirements. To obtain CIS certification, an 
applicant must submit an application to the Bureau for review and 
approval that:
    (i) Demonstrates that all radio transmitters used as part of the CIS 
have appropriate equipment authorizations pursuant to Commission rules 
in part 2 of this chapter;
    (ii) Demonstrates that the CIS is designed and will be configured to 
locate devices solely within a correctional facility;
    (iii) Describes the methodology to be used in analyzing data 
collected by the CIS and demonstrates that such methodology is 
adequately robust to ensure that the particular wireless device is in 
fact located within a correctional facility and includes specific data 
analysis benchmarks designed to ensure successful detection, such as 
rate of detection of contraband versus non-contraband devices and 
relevant sample size (e.g. number of devices observed and length of 
observation period);
    (iv) Demonstrates that the CIS will secure and protect all 
information or data collected as part of its intended use;
    (v) Demonstrates that the CIS will not interfere with emergency 911 
calls;
    (vi) Describes whether the CIS requires a spectrum or network access 
agreement (e.g., a spectrum leasing arrangement or roaming agreement) to 
be authorized to operate; and
    (vii) Includes a proposed test plan for subsequent site-based 
testing of each CIS, that must include detailed descriptions and 
technical specifications to facilitate Commission review of whether the 
system satisfies its legal requirements and technically functions as 
anticipated.
    (2) Marketing and sales. CIS that are certified for use in 
qualifying requests for disabling of contraband devices may be marketed 
or sold only to correctional facilities or entities that will provide 
contraband interdiction services to such facilities.
    (3) Site-based testing and self-certification requirements--(i) 
Site-based testing. A CIS operator seeking to use the CIS to submit 
qualifying requests for disabling must test a certified CIS at each 
location where it intends to operate. Thereafter, the CIS operator must 
file with the Bureau a self-certification that complies with paragraph 
(b)(3)(ii) of this section, confirming that the testing at that specific 
correctional facility is complete and successful. The CIS operator must 
serve notice of the testing on all relevant wireless providers prior to 
testing and provide such wireless providers a reasonable opportunity to 
participate in the tests. Relevant wireless providers include any 
wireless provider holding a spectrum license that:
    (A) Authorizes operation on the frequencies on which the CIS seeks 
to detect contraband use; and
    (B) Authorizes service in the geographic area (e.g., census tract, 
county, Partial Economic Area (PEA), Economic Area (EA), Cellular Market 
Area (CMA), Regional Economic Area Grouping (REAG)) within which the 
correctional facility is located.
    (ii) Self-certification. Following the testing, and to be eligible 
for use in conjunction with qualifying requests for disabling, a CIS 
operator must file a self-certification with the Bureau that:
    (A) Identifies the correctional facility where it seeks to deploy;
    (B) Attests that applicable Federal or state criminal statutes 
prohibit the possession or operation of contraband devices within the 
correctional facility (and includes the applicable Federal or state 
criminal statutory provision);

[[Page 33]]

    (C) Describes the results of on-site tests of the certified CIS 
conducted at the correctional facility;
    (D) Attests that the on-site testing was performed consistent with 
the approved test plans for the certified CIS and that the CIS 
deployment minimizes the risk of disabling a non-contraband device;
    (E) Identifies whether any relevant wireless providers participated 
in the testing, and provides proof that the relevant wireless providers 
were given notice regarding the testing and a reasonable opportunity to 
participate;
    (F) Includes proof of any spectrum and/or network access agreement 
(e.g., a spectrum leasing arrangement and/or roaming agreement) required 
to be authorized to operate and/or for the system to function 
effectively;
    (G) Includes proof that the self-certification was served via 
electronic means on all relevant wireless providers; and
    (H) Includes an attestation from the DCFO verifying that all 
information contained in the self-certification is true and accurate.
    (I) The self-certification must be filed in accordance with part 1, 
subpart F, of this chapter.
    (4) Submitting objections. Wireless providers may submit objections 
to the Bureau within five business days from the certification filing 
date. Any such objections must be served on the DCFO and the CIS 
operator.
    (5) Recertification. At least every three years after the initial 
self-certification, CIS operators seeking to maintain the ability to 
submit qualifying requests through a DCFO for contraband device 
disabling must retest their systems and recertify them for continued CIS 
accuracy. Recertifications must comply with the same rules and filing 
instructions that apply to the initial self-certification.
    (6) Suspension of CIS eligibility. The Bureau may suspend CIS 
certification generally or at a particular facility if subsequent 
credible information calls into question a system's reliability.
    (7) Records maintenance. To ensure the integrity and proper 
operation of CISs, a CIS operator must retain records of all information 
supporting each request for disabling and the basis for disabling each 
device, including copies of all documents submitted in the qualifying 
request, for at least five years following the date of submission of the 
relevant disabling request. CIS operators of systems that have been 
tested and approved for use in qualifying requests must make available 
all records upon request from the Bureau.
    (c) Disabling contraband wireless devices. A DCFO may request that a 
CMRS licensee disable a contraband wireless device that has been 
detected in a correctional facility by a CIS that has been certified in 
accordance with paragraph (b) of this section. Absent objections from a 
wireless provider, as described under paragraph (b)(4) of this section, 
the DCFO may submit a qualifying request to a wireless provider 
beginning on the sixth business day after the later of the self-
certification filing or actual service, as described under paragraph 
(b)(3)(ii) of this section.
    (1) DCFO list. The Commission will maintain a publicly available 
list of DCFOs that are authorized to transmit qualifying disabling 
requests. Authorized DCFOs that seek to be recognized on the 
Commission's DCFO list must send a letter to the Commission's Contraband 
Ombudsperson, signed by the relevant state attorney general or the 
relevant Bureau of Prisons Regional Director and providing:
    (i) The individual's name;
    (ii) The individual's official government position; and
    (iii) A list of correctional facilities over which the individual 
has oversight and management authority.
    (2) Qualifying request. A qualifying request must be made in 
writing, contain the certifications in paragraph (c)(2)(i) of this 
section and the device and correctional facility identifying information 
in paragraph (c)(2)(ii) of this section, and be signed by the 
appropriate DCFO. The DCFO must transmit a qualifying request to a CMRS 
licensee using a secure communication means that will provide certainty 
regarding the identity of both the sending and receiving parties. A CMRS 
licensee must adopt a method, or use an existing method, for receiving 
secured and verified qualifying requests.

[[Page 34]]

    (i) Certifications. A qualifying request must include the following 
certifications by the DCFO:
    (A) A CIS that has been certified in accordance with paragraph (b) 
of this section was used to gather the contraband subscriber and device 
information populated in the qualifying request;
    (B) The certified CIS was used to identify contraband wireless 
devices operating in a correctional facility where the CIS has been 
tested and self-certified for operational readiness and for use in 
qualifying requests, and the identification of contraband wireless 
devices occurred within 30 days immediately prior to the date of the 
qualifying request submission;
    (C) The DCFO has reviewed the list of contraband wireless devices 
and attests that it is accurate; and
    (D) It is a violation of applicable state or Federal criminal 
statutes to possess or operate a contraband device in the correctional 
facility.
    (ii) Device and correctional facility identifying information. The 
qualifying request must identify the contraband wireless device to be 
disabled and the correctional facility by providing the following 
information:
    (A) Identifiers sufficient to:
    (1) Identify the applicable wireless service provider;
    (2) Uniquely describe each of the contraband wireless devices in 
question at the subscription level; and
    (3) Uniquely describe each of the contraband wireless devices in 
question at the device-level;
    (B) Name of the correctional facility at which the contraband 
wireless device(s) were identified; and
    (C) Street address of the correctional facility at which the 
contraband wireless device(s) were identified.
    (3) Licensee actions upon receipt of a qualifying request. Upon 
receiving a request from a DCFO to disable a contraband wireless device, 
a licensee providing CMRS service must verify that the request contains 
the required information for a qualifying request, as defined in 
paragraph (c)(2) of this section.
    (i) Disabling upon receipt of a qualifying request and timing. If 
the qualifying request contains the required information, and does not 
contain an error in the device identifying information preventing the 
licensee from being able to disable the device, a licensee must, within 
two business days of receipt of the qualifying request, disable the 
contraband wireless device from using the wireless provider's network at 
both the device and subscriber level and take reasonable and practical 
steps to prevent the contraband wireless device from being used on 
another wireless provider's network.
    (ii) Rejection of a qualifying request and timing. A licensee may 
reject a qualifying request within two business days of receipt of a 
qualifying request if it does not include the information required for a 
qualifying request or, with respect to a relevant device, the request 
contains an error in the device-identifying information preventing the 
licensee from being able to disable the device.
    (iii) Customer outreach. A licensee may immediately disable a 
contraband wireless device without any customer outreach, or a licensee 
may contact the customer of record through any available means to notify 
them that the device will be disabled, but any such notice does not 
modify the licensee's obligation to comply with paragraphs (c)(3)(i) and 
(ii) of this section.
    (iv) Notification to the Designated Correctional Facility Official. 
Within two business days of receiving a qualifying request from a DCFO, 
a licensee must inform the DCFO whether the request has been granted or 
rejected.
    (4) Reversals. A licensee may reverse a disabled wireless device if 
it determines that the wireless device was identified erroneously as 
contraband. The licensee must promptly inform the DCFO of the 
erroneously identified wireless device.
    (i) DCFO involvement. Prior to reversing a disabling action, a 
wireless provider that determines that a device may have been 
erroneously identified as contraband may request that the DCFO review 
and confirm the information provided in a qualifying request pursuant to 
which the device was previously disabled. To trigger DCFO involvement, 
the wireless provider must provide the DCFO with:
    (A) The date of the qualifying request;

[[Page 35]]

    (B) The identifying information provided for the device; and
    (C) Any evidence supporting the wireless provider's belief that the 
device was erroneously identified.
    (ii) DCFO response. Upon receipt of a request from a wireless 
provider, the DCFO should review the qualifying request and determine 
whether the device in question was erroneously identified and either 
confirm the validity of the identifying information contained in the 
qualifying request or acknowledge the error and direct the carrier to 
restore service to the device.
    (iii) Restoration of service. In the event the DCFO directs the 
wireless provider to reverse the disabling, the wireless provider must, 
within two business days, restore service to the device and reverse any 
actions taken to prevent the device from accessing other wireless 
provider networks.
    (iv) Wireless provider action in absence of timely DCFO response. In 
the event the DCFO does not respond to a request from a wireless 
provider for review of a qualifying request within two business days, 
the wireless provider may proceed with reversing the disabling action.
    (v) Notice of reversals. The DCFO must provide notice to the 
Contraband Ombudsperson of the number of erroneously disabled devices on 
a quarterly basis at the end of any quarter during which a device 
disabling was reversed.
    (d) Notification to Managed Access System (MAS) operators of 
wireless provider technical changes--(1) Notification requirements. CMRS 
licensees leasing spectrum to MAS operators must provide 90 days' 
advance notice to MAS operators of the following network changes 
occurring within 15 miles of the correctional facility, unless parties 
modify notification arrangements through mutual agreement:
    (i) Adding a new frequency band to service offerings;
    (ii) Deploying a new air interface technology or changing an 
existing air interface technology; and/or
    (iii) Adding, relocating, or removing a site.
    (2) Good faith negotiations. CMRS licensee lessors and MAS operator 
lessees must negotiate in good faith to reach an agreement for 
notification for other types of network adjustments not covered by the 
notice requirement set forth in paragraph (d)(1) of this section and for 
the parties' treatment of confidential information contained in 
notifications required pursuant to this section and/or negotiated 
between the parties.
    (3) Emergency network changes exception. CMRS licensees leasing 
spectrum to managed access systems (MAS) operators are not required to 
provide 90 days' advance notice to MAS operators of network technical 
changes occurring within 15 miles of the correctional facility that are 
required due to emergency and disaster preparedness. CMRS licensees must 
provide notice of these technical changes immediately after the 
exigency.

(see Sec. Sec.  22.509, 22.717, and 22.949) and in part 1 of this 
chapter.
    (a) Separate applications. Any applicant that files an application 
knowing that it will be mutually exclusive with one or more applications 
should not include in the mutually exclusive application a request for 
other channels or facilities that would not, by themselves, render the 
application mutually exclusive with those other applications. Instead, 
the request for such other channels or facilities should be filed in a 
separate application.
    (b) Filing groups. Pending mutually exclusive applications are 
processed in filing groups. Mutually exclusive applications in a filing 
group are given concurrent consideration. The Commission may dismiss as 
defective (pursuant to Sec.  1.945 of this chapter) any mutually 
exclusive application(s) whose filing date is outside of the date range 
for inclusion in the filing group. The types of filing groups used in 
day-to-day application processing are specified in paragraph (c)(3) of 
this section. A filing group is one of the following types:
    (1) Same-day filing group. A same-day filing group comprises all 
mutually exclusive applications whose filing date is the same day, which 
is normally the filing date of the first-filed application(s).
    (2) Thirty-day notice and cut-off filing group. A 30-day notice and 
cut-off filing group comprises mutually exclusive applications whose 
filing date is no later than thirty (30) days after the date of the 
Public Notice listing the first-filed application(s) (according to the 
filing dates) as acceptable for filing.
    (3) Window filing group. A window filing group comprises mutually 
exclusive applications whose filing date is within an announced filing 
window. An announced filing window is a period of time between and 
including two specific dates, which are the first and last dates on 
which applications (or amendments) for a particular purpose may be 
accepted for filing. In the case of a one-day window, the two dates are 
the same. The dates are made known to the public in advance.
    (c) Procedures. Generally, the Commission may grant one application 
in a filing group of mutually exclusive applications and dismiss the 
other application(s) in the filing that are excluded by that grant, 
pursuant to Sec.  1.945 of this chapter.
    (1) Selection methods. In selecting the application to grant, the 
Commission will use competitive bidding.
    (2) Dismissal of applications. The Commission may dismiss any 
application in a filing group that is defective or otherwise subject to 
dismissal under Sec.  1.945 of this chapter, either before or after 
employing selection procedures.
    (3) Type of filing group used. Except as otherwise provided in this 
part, the type of filing group used in the processing of two or more 
mutually exclusive applications depends upon the purpose(s) of the 
applications.
    (i) If any mutually exclusive application filed on the earliest 
filing date is an application for modification and none of the mutually 
exclusive applications is a timely-filed application for renewal, a 
same-day filing group is used.
    (ii) If all of the mutually exclusive applications filed on the 
earliest filing

[[Page 44]]

date are applications for initial authorization, a 30-day notice and 
cut-off filing group is used.
    (4) Disposition. If there is only one application in any type of 
filing group, the Commission may grant that application and dismiss 
without prejudice any mutually exclusive applications not in the filing 
group. If there is more than one mutually exclusive application in a 
filing group, the Commission disposes of these applications as follows:
    (i) Applications in a 30-day notice and cut-off filing group. (A) If 
all of the mutually exclusive applications in a 30-day notice and cut-
off filing group are applications for initial authorization, the FCC 
administers competitive bidding procedures in accordance with Sec. Sec.  
22.201 through 22.227 and subpart Q of part 1 of this chapter, as 
applicable. After such procedures, the application of the successful 
bidder may be granted and the other applications may be dismissed 
without prejudice.
    (B) If any of the mutually exclusive applications in a 30-day notice 
and cut-off filing group is an application for modification, the 
Commission may attempt to resolve the mutual exclusivity by facilitating 
a settlement between the applicants. If a settlement is not reached 
within a reasonable time, the FCC may designate all applications in the 
filing group for comparative consideration in a hearing. In this event, 
the result of the hearing disposes all of the applications in the filing 
group.
    (ii) Applications in a same-day filing group. If there are two or 
more mutually exclusive applications in a same-day filing group, the 
Commission may attempt to resolve the mutual exclusivity by facilitating 
a settlement between the applicants. If a settlement is not reached 
within a reasonable time, the Commission may designate all applications 
in the filing group for comparative consideration in a hearing. In this 
event, the result of the hearing disposes of all of the applications in 
the filing group.
    (iii) Applications in a window filing group. Applications in a 
window filing group are processed in accordance with the procedures for 
a 30-day notice and cut-off filing group in paragraph (c)(4)(ii) of this 
section.
    (d) Terminology. For the purposes of this section, terms have the 
following meanings:
    (1) The filing date of an application is the date on which that 
application was received in a condition acceptable for filing or the 
date on which the most recently filed major amendment to that 
application was received, whichever is later, excluding major amendments 
in the following circumstances:
    (i) The major amendment reflects only a change in ownership or 
control found by the Commission to be in the public interest;
    (ii) The major amendment as received is defective or otherwise found 
unacceptable for filing; or
    (iii) The application being amended has been designated for hearing 
and the Commission or the presiding officer accepts the major amendment.
    (2) An application for initial authorization is:
    (i) Any application requesting an authorization for a new system or 
station;
    (ii) Any application requesting authorization for an existing 
station to operate on an additional channel, unless the additional 
channel is for paired two-way radiotelephone operation, is in the same 
frequency range as the existing channel(s), and will be operationally 
integrated with the existing channel(s) such as by trunking;
    (iii) Any application requesting authorization for a new transmitter 
at a location more than 2 kilometers (1.2 miles) from any existing 
transmitters of the applicant licensee on the requested channel or 
channel block; or
    (iv) Any application to expand the Cellular Geographic Service Area 
of an existing Cellular system. See Sec.  22.911.
    (v) Any ``short-form'' application (filed on FCC Form 175) 
requesting a new paging geographic area authorization.

Sec.  22.143  Construction prior to grant of application.

    Applicants may construct facilities in the Public Mobile services 
prior to grant of their applications, subject to the provisions of this 
section, but must not operate such facilities until the FCC grants an 
authorization. If the conditions stated in this section are not met, 
applicants must not begin to construct facilities in the Public Mobile 
Services.
    (a) When applicants may begin construction. An applicant may begin 
construction of a facility 35 days after the date of the Public Notice 
listing the application for that facility as acceptable for filing.
    (b) Notification to stop. If the FCC for any reason determines that 
construction should not be started or should be stopped while an 
application is pending, and so notifies the applicant, orally (followed 
by written confirmation) or in writing, the applicant must not begin 
construction or, if construction has begun, must stop construction 
immediately.
    (c) Assumption of risk. Applicants that begin construction pursuant 
to this section before receiving an authorization do so at their own 
risk and have no recourse against the United States for any losses 
resulting from:
    (1) Applications that are not granted;
    (2) Errors or delays in issuing Public Notices;
    (3) Having to alter, relocate or dismantle the facility; or
    (4) Incurring whatever costs may be necessary to bring the facility 
into compliance with applicable laws, or FCC rules and orders.
    (d) Conditions. Except as indicated, all pre-grant construction is 
subject to the following conditions:
    (1) The application is not mutually exclusive with any other 
application, except for successful bidders and tentative selectees in 
the Cellular Radiotelephone Service;
    (2) No petitions to deny the application have been filed;
    (3) The application does not include a request for a waiver of one 
or more FCC rules;
    (4) For any construction or alteration that would exceed the 
requirements of Sec.  17.7 of this chapter, the licensee has notified 
the appropriate Regional Office of the Federal Aviation Administration 
(FAA Form 7460-1), secured a valid FAA determination of ``no hazard,'' 
and received antenna height clearance and obstruction marking and 
lighting specifications (FCC Form 854R) from the FCC for the proposed 
construction or alteration.
    (5) The applicant has indicated in the application that the proposed 
facility would not have a significant environmental effect, in 
accordance with Sec. Sec.  1.1301 through 1.1319 of this chapter; and,
    (6) Under applicable international agreements and rules in this 
part, individual coordination of the proposed channel assignment(s) with 
a foreign administration is not required.

77 FR 3954, Jan. 26, 2012; 79 FR 72151, Dec. 5, 2014]



Sec.  22.150  Standard pre-filing technical coordination procedure.

    For operations on certain channels in the Public Mobile Services, 
carriers must attempt to coordinate the proposed use of spectrum with 
other spectrum users prior to filing an application for authority to 
operate a station. Rules requiring this procedure for specific channels 
and types of stations are contained in the subparts governing the 
individual Public Mobile Services.
    (a) Coordination comprises two steps--notification and response. 
Each step may be accomplished orally or in writing.
    (b) Notification must include relevant technical details of the 
proposal. At minimum, this should include the following:
    (1) Geographical coordinates of the antenna site(s).
    (2) Transmitting and receiving channels to be added or changed.
    (3) Transmitting power, emission type and polarization.
    (4) Transmitting antenna pattern and maximum gain.
    (5) Transmitting antenna height above ground level.
    (c) Applicants and licensees receiving notification must respond 
promptly, even if no channel usage conflicts are anticipated. If any 
notified party fails

[[Page 46]]

to respond within 30 days, the applicant may file the application 
without a response from that party.
    (d) The 30-day period begins on the date the notification is 
submitted to the Commission via the ULS. If the notification is by mail, 
this date may be ascertained by:
    (1) The return receipt on certified mail,
    (2) The enclosure of a card to be dated and returned by the party 
being notified, or
    (3) A reasonable estimate of the time required for the mail to reach 
its destination. In this case, the date when the 30-day period will 
expire must be stated in the notification.
    (e) All channel usage conflicts discovered during the coordination 
process should be resolved prior to filing of the application. If the 
applicant is unable or unwilling to resolve a particular conflict, the 
application may be accepted for filing if it contains a statement 
describing the unresolved conflict and a brief explanation of the 
reasons why a resolution was not achieved.
    (f) If a number of changes in the technical parameters of a proposed 
facility become necessary during the course of the coordination process, 
an attempt should be made to minimize the number of separate 
notifications. If the changes are incorporated into a completely revised 
notice, the items that were changed from the previous notice should be 
identified.
    (g) In situations where subsequent changes are not numerous or 
complex, the party receiving the changed notification should make an 
effort to respond in less than 30 days. If the applicant believes a 
shorter response time is reasonable and appropriate, it should so 
indicate in the notice and suggest a response date.
    (h) If a subsequent change in the technical parameters of a proposed 
facility could not affect the facilities of one or more of the parties 
that received an initial notification, the applicant is not required to 
coordinate that change with these parties. However, these parties must 
be advised of the change and of the opinion that coordination is not 
required.

Sec.  22.165  Additional transmitters for existing systems.

    A licensee may operate additional transmitters at additional 
locations on the same channel or channel block as its existing system 
without obtaining prior Commission approval provided:
    (a) International coordination. The locations and/or technical 
parameters of the additional transmitters are such that individual 
coordination of the channel assignment(s) with a foreign administration, 
under applicable international agreements and rules in this part, is not 
required.
    (b) Antenna structure registration. Certain antenna structures must 
be registered with the Commission prior to construction or alteration. 
Registration requirements are contained in part 17 of this chapter.
    (c) Environmental. The additional transmitters must not have a 
significant environmental effect as defined by Sec. Sec.  1.1301 through 
1.1319 of this chapter.
    (d) Paging and Radiotelephone Service. The provisions in this 
paragraph apply for stations in the Paging and Radiotelephone Service.
    (1) The interfering contours of the additional transmitter(s) must 
be totally encompassed by the composite interfering contour of the 
existing station (or stations under common control of the applicant) on 
the same channel, except that this limitation does not apply to 
nationwide network paging stations or in-building radiation systems.
    (2) [Reserved]
    (3) The additional transmitters must not operate on control channels 
in the 72-76 MHz, 470-512 MHz, 928 MHz, 932 MHz, 941 MHz or 959 MHz 
frequency ranges.
    (e) Cellular Radiotelephone Service. The service area boundaries 
(SABs) of the additional transmitters, as calculated by the method set 
forth in Sec.  22.911(a), must not cause an expansion of the Cellular 
Geographic Service Area (CGSA), and must not extend outside the CGSA 
boundary into Unserved Area unless such extension is less than

[[Page 47]]

130 contiguous square kilometers (50 contiguous square miles). The 
licensee must seek prior approval (using FCC Form 601) regarding any 
transmitters to be added under this section that would cause an 
expansion of the CGSA, or an SAB extension of 130 contiguous square 
kilometers (50 contiguous square miles) or more, into Unserved Area. See 
Sec. Sec.  22.912, 22.953.
    (f) Air-ground Radiotelephone Service. Ground stations may be added 
to Commercial Aviation air-ground systems at previously established 
ground station locations, pursuant to Sec.  22.859, subject to 
compliance with the applicable technical rules. This section does not 
apply to General Aviation air-ground stations.
    (g) Rural Radiotelephone Service. A ``service area'' and 
``interfering contours'' must be determined using the same method as for 
stations in the Paging and Radiotelephone Service. The service area and 
interfering contours so determined for the additional transmitter(s) 
must be totally encompassed by the similarly determined composite 
service area contour and predicted interfering contour, respectively, of 
the existing station on the same channel. This section does not apply to 
Basic Exchange Telecommunications Radio Systems.
    (h) Offshore Radiotelephone Service. This section does not apply to 
stations in the Offshore Radiotelephone Service.
    (i) Provision of information upon request. Upon request by the FCC, 
licensees must supply administrative or technical information concerning 
the additional transmitters. At the time transmitters are added pursuant 
to this section, licensees must make a record of the pertinent technical 
and administrative information so that such information is readily 
available. See Sec.  22.303.

Sec.  22.301  [Reserved]



Sec.  22.303  [Reserved]



Sec.  22.305  Operator and maintenance requirements.

    FCC operator permits and licenses are not required to operate, 
repair or maintain equipment authorized in the Public Mobile Services. 
Station licensees are responsible for the proper operation and 
maintenance of their stations, and for compliance with FCC rules.



Sec.  22.307  Operation during emergency.

    Licensees of stations in the Public Mobile services may, during a 
period of emergency in which normal communications facilities are 
disrupted as a result of hurricane, flood, earthquake or other natural 
disaster, civil unrest, widespread vandalism, national emergencies or 
emergencies declared by Executive Order of the President, use their 
stations to temporarily provide emergency communications services in a 
manner or configuration not normally allowed by this part, provided that 
such operations comply with the provisions of this section.
    (a) Technical limitations. Public Mobile stations providing 
temporary emergency communications service must not transmit:
    (1) On channels other than those authorized for normal operations.
    (2) With power in excess of that authorized for normal operations;
    (3) Emission types other than those authorized for normal 
operations.
    (b) Discontinuance. Temporary emergency use of Public Mobile 
stations must be discontinued as soon as normal communication facilities 
are restored. The FCC may, at any time, order the discontinuance of any 
such emergency communication services.



Sec.  22.313  Station identification.

    The licensee of each station in the Public Mobile Services must 
ensure that the transmissions of that station are identified in 
accordance with the requirements of this section.
    (a) Station identification is not required for transmission by:
    (1) Stations in the Cellular Radiotelephone Service;
    (2) General aviation ground stations in the Air-ground 
Radiotelephone Service;
    (3) [Reserved]
    (4) Stations using Basic Exchange Telephone Radio Systems in the 
Rural Radiotelephone Service;
    (5) [Reserved]
    (6) Stations operating pursuant to paging geographic area 
authorizations.

identification must be transmitted each hour within five minutes of the 
hour, or upon completion of the first transmission after the hour. 
Transmission of station identification may be temporarily delayed to 
avoid interrupting the continuity of any public communication in 
progress, provided that station identification is transmitted at the 
conclusion of that public communication.
    (c) Station identification must be transmitted by telephony using 
the English language or by telegraphy using the international Morse 
code, and in a form that can be received using equipment appropriate for 
the modulation type employed, and understood without the use of 
unscrambling devices, except that, alternatively, station identification 
may be transmitted digitally, provided that the licensee

[[Page 50]]

provides the Commission with information sufficient to decode the 
digital transmission to ascertain the call sign. Station identification 
comprises transmission of the call sign assigned by the Commission to 
the station, however, the following may be used in lieu of the call 
sign.
    (1) For transmission from subscriber operated transmitters, the 
telephone number or other designation assigned by the carrier, provided 
that a written record of such designations is maintained by the carrier;
    (2) For general aviation airborne mobile stations in the Air-Ground

    The channels allocated for use in the Public Mobile Services are 
listed in the applicable subparts of this part. Channels and channel 
blocks are assigned in such a manner as to facilitate the rendition of 
service on an interference-free basis in each service area. Except as 
otherwise provided in this part, each channel or channel block is 
assigned exclusively to one licensee in each service area. All 
applicants for, and licensees of, stations in the Public Mobile Services 
shall cooperate in the selection and use of channels in order to 
minimize interference and obtain the most efficient use of the allocated 
spectrum.

Sec.  22.352  Protection from interference.

    Public Mobile Service stations operating in accordance with 
applicable FCC rules and the terms and conditions of their 
authorizations are normally considered to be non-interfering. If the FCC 
determines, however, that interference that significantly interrupts or 
degrades a radio service is being caused, it may, in accordance with the 
provisions of sections 303(f) and 316 of the Communications Act of 1934, 
as amended, (47 U.S.C. 303(f), 316), require modifications to any Public 
Mobile station as necessary to eliminate such interference.
    (a) Failure to operate as authorized. Any licensee causing 
interference to the service of other stations by failing to operate its 
station in full accordance with its authorization and applicable FCC 
rules shall discontinue all transmissions, except those necessary for 
the immediate safety of life or property, until it can bring its station 
into full compliance with the authorization and rules.
    (b) Intermodulation interference. Licensees should attempt to 
resolve such interference by technical means.
    (c) Situations in which no protection is afforded. Except as 
provided elsewhere in this part, no protection from interference is 
afforded in the following situations:
    (1) Interference to base receivers from base or fixed transmitters. 
Licensees should attempt to resolve such interference by technical means 
or operating arrangements.
    (2) Inteference to mobile receivers from mobile transmitters. No 
protection is provided against mobile-to-mobile interference.
    (3) Interference to base receivers from mobile transmitters. No 
protection is provided against mobile-to-base interference.
    (4) Interference to fixed stations. Licensees should attempt to 
resolve such interference by technical means or operating arrangements.
    (5) Anomalous or infrequent propagation modes. No protection is 
provided against interference caused by tropospheric and ionospheric 
propagation of signals.
    (6) Facilities for which the Commission is not notified. No 
protection is provided against interference to the service of any 
additional or modified transmitter operating pursuant to Sec.  1.929 or 
Sec.  22.165, unless and until the licensee modifies its authorization 
using FCC Form 601.

[[Page 51]]

    (7) In-building radiation systems. No protection is provided against 
interference to the service of in-building radiation systems (see Sec.  
22.383).

Sec.  22.353  Blanketing interference.

    Licensees of Public Mobile Services stations are responsible for 
resolving cases of blanketing interference in accordance with the 
provisions of this section.
    (a) Except as provided in paragraph (c) of this section, licensees 
must resolve any cases of blanketing interference in their area of 
responsibility caused by operation of their transmitter(s) during a one-
year period following commencement of service from new or modified 
transmitter(s). Interference must be resolved promptly at no cost to the 
complainant.
    (b) The area of responsibility is that area in the immediate 
vicinity of the transmitting antenna of stations where the field 
strength of the electromagnetic radiation from such stations equals or 
exceeds 115 dB[micro]V/m. To determine the radial distance to the 
boundary of this area, the following formula must be used:
[GRAPHIC] [TIFF OMITTED] TR17NO94.007

where d is the radial distance to the boundary, in kilometers
p is the radial effective radiated power, in kilowatts


The maximum effective radiated power in the pertinent direction, without 
consideration of the antenna's vertical radiation pattern or height, 
must be used in the formula.
    (c) Licensees are not required to resolve blanketing interference to 
mobile receivers or non-RF devices or blanketing interference occurring 
as a result of malfunctioning or mistuned receivers, improperly 
installed consumer antenna systems, or the use of high gain antennas or 
antenna booster amplifiers by consumers.
    (d) Licensees that install transmitting antennas at a location where 
there are already one or more transmitting antennas are responsible for 
resolving any new cases of blanketing interference in accordance with 
this section.
    (e) Two or more licensees that concurrently install transmitting 
antennas at the same location are jointly responsible for resolving 
blanketing interference cases, unless the FCC can readily determine 
which station is causing the interference, in which case the licensee of 
that station is held fully responsible.
    (f) After the one year period of responsibility to resolve 
blanketing interference, licensees must provide upon request technical 
information to complainants on remedies for blanketing interference.



Sec.  22.355  Frequency tolerance.

    Except as otherwise provided in this part, the carrier frequency of 
each transmitter in the Public Mobile Services must be maintained within 
the tolerances given in Table C-1 of this section.

[61 FR 54099, Oct. 17, 1996]



Sec.  22.357  Emission types.

    Any authorized station in the Public Mobile Services may transmit 
emissions of any type(s) that comply with the applicable emission rule, 
i.e. Sec.  22.359, Sec.  22.861 or Sec.  22.917.

[70 FR 19308, Apr. 13, 2005]



Sec.  22.359  Emission limitations.

    The rules in this section govern the spectral characteristics of 
emissions in the Public Mobile Services, except for the Air-Ground 
Radiotelephone Service (see Sec.  22.861, instead) and the Cellular 
Radiotelephone Service (see Sec.  22.917, instead).

[[Page 52]]

    (a) Out of band emissions. The power of any emission outside of the 
authorized operating frequency ranges must be attenuated below the 
transmitting power (P) by a factor of at least 43 + 10 log (P) dB.
    (b) Measurement procedure. Compliance with these rules is based on 
the use of measurement instrumentation employing a resolution bandwidth 
of 30 kHz or more. In the 60 kHz bands immediately outside and adjacent 
to the authorized frequency range or channel, a resolution bandwidth of 
at least one percent of the emission bandwidth of the fundamental 
emission of the transmitter may be employed. A narrower resolution 
bandwidth is permitted in all cases to improve measurement accuracy 
provided the measured power is integrated over the full required 
measurement bandwidth (i.e., 30 kHz or 1 percent of emission bandwidth, 
as specified). The emission bandwidth is defined as the width of the 
signal between two points, one below the carrier center frequency and 
one above the carrier center frequency, outside of which all emissions 
are attenuated at least 26 dB below the transmitter power.
    (c) Alternative out of band emission limit. Licensees in the Public 
Mobile Services may establish an alternative out of band emission limit 
to be used at specified frequencies (band edges) in specified 
geographical areas, in lieu of that set forth in this section, pursuant 
to a private contractual arrangement of all affected licensees and 
applicants. In this event, each party to such contract shall maintain a 
copy of the contract in their station files and disclose it to 
prospective assignees or transferees and, upon request, to the FCC.
    (d) Interference caused by out of band emissions. If any emission 
from a transmitter operating in any of the Public Mobile Services 
results in interference to users of another radio service, the FCC may 
require a greater attenuation of that emission than specified in this 
section.

[70 FR 19308, Apr. 13, 2005]



Sec.  22.365  Antenna structures; air navigation safety.

    Licensees that own their antenna structures must not allow these 
antenna structures to become a hazard to air navigation. In general, 
antenna structure owners are responsible for registering antenna 
structures with the FCC if required by part 17 of this chapter, and for 
installing and maintaining any required marking and lighting. However, 
in the event of default of this responsibility by an antenna structure 
owner, each FCC permittee or licensee authorized to use an affected 
antenna structure will be held responsible by the FCC for ensuring that 
the antenna structure continues to meet the requirements of part 17 of 
this chapter. See Sec.  17.6 of this chapter.
    (a) Marking and lighting. Antenna structures must be marked, lighted 
and maintained in accordance with part 17 of this chapter and all 
applicable rules and requirements of the Federal Aviation 
Administration.
    (b) Maintenance contracts. Antenna structure owners (or licensees 
and permittees, in the event of default by an antenna structure owner) 
may enter into contracts with other entities to monitor and carry out 
necessary maintenance of antenna structures. Antenna structure owners 
(or licensees and permittees, in the event of default by an antenna 
structure owner) that make such contractual arrangements continue to be 
responsible for the maintenance of antenna structures in regard to air 
navigation safety.

[61 FR 4365, Feb. 6, 1996]



Sec.  22.377  Certification of transmitters.

    Transmitters used in the Public Mobile Services, including those 
used with signal boosters, in-building radiation systems and cellular 
repeaters, must be certificated for use in the radio services regulated 
under this part. Transmitters must be certificated when the station is 
ready for service, not necessarily at the time of filing an application. 
The FCC may list as certificated only transmitters that are capable of 
meeting all technical requirements of the rules governing the service in 
which they will operate. The procedure for obtaining certification is 
set forth in part 2 of this chapter.

[78 FR 25174, Apr. 29, 2013]

Sec.  22.379  RF exposure.

    Licensees and manufacturers shall ensure compliance with the 
Commission's radio frequency exposure requirements in Sec. Sec.  
1.1307(b), 2.1091, and 2.1093 of this chapter, as appropriate. 
Applications for equipment authorization of mobile or portable devices 
operating under this section must contain a statement confirming 
compliance with these requirements. Technical information showing the 
basis for this statement must be submitted to the Commission upon 
request.

[85 FR 18150, Apr. 1, 2020]



Sec.  22.383  In-building radiation systems.

    Licensees may install and operate in-building radiation systems 
without applying for authorization or notifying the FCC, provided that 
the locations of the in-building radiation systems are within the 
protected service area of the licensee's authorized transmitter(s) on 
the same channel or channel block.

Subpart D [Reserved]



               Subpart E_Paging and Radiotelephone Service



Sec.  22.501  Scope.

    The rules in this subpart govern the licensing and operation of 
public mobile paging and radiotelephone stations. The licensing and 
operation of these stations are also subject to rules elsewhere in this 
part that apply generally to the Public Mobile Services. However, in 
case of conflict, the rules in this subpart govern.



Sec.  22.503  Paging geographic area authorizations.

    The FCC considers applications for and issues paging geographic area 
authorizations in the Paging and Radiotelephone Service in accordance 
with the rules in this section. Each paging geographic area 
authorization contains conditions requiring compliance with paragraphs 
(h) and (i) of this section.
    (a) Channels. The FCC may issue a paging geographic area 
authorization for any channel listed in Sec.  22.531 of this part or for 
any channel pair listed in Sec.  22.561 of this part.
    (b) Paging geographic areas. The paging geographic areas are as 
follows:
    (1) The Nationwide paging geographic area comprises the District of 
Columbia and all States, Territories and possessions of the United 
States of America.
    (2) Major Economic Areas (MEAs) and Economic Areas (EAs) are defined 
below. EAs are defined by the Department of Commerce, Bureau of Economic 
Analysis. See Final Redefinition of the MEA Economic Areas, 60 FR 13114 
(March 10, 1995). MEAs are based on EAs. In addition to the Department 
of Commerce's 172 EAs, the FCC shall separately license Guam and the 
Northern Mariana Islands, Puerto Rico and the United States Virgin 
Islands, and American Samoa, which have been assigned FCC-created EA 
numbers 173-175, respectively, and MEA numbers 49-51, respectively.
    (3) The 51 MEAs are composed of one or more EAs as defined in the 
following table:

------------------------------------------------------------------------

    (c) Availability. The FCC may determine whether to issue a paging 
geographic area authorization for any specific channel or channel pair 
in any specific paging geographic area. The FCC may replace existing 
site specific authorizations for facilities on a channel or channel pair 
located in a paging geographic area with a paging geographic area 
authorization for that channel or channel pair, if in its sole 
discretion, the FCC determines that the public interest would be served 
by such replacement.
    (d) Filing windows. The FCC accepts applications for paging 
geographic area authorizations only during filing windows. The FCC 
issues Public Notices announcing in advance the dates of the filing 
windows, and the specific paging geographic areas and channels for which 
applications may be accepted.
    (e) One grant per geographic area. The FCC may grant one and only 
one application for a paging geographic area authorization for any 
specific channel or channel pair in any specific paging geographic area 
defined in paragraph (b) of this section. Selection from among mutually 
exclusive applications for a paging geographic area authorization will 
be made in accordance with the procedures in Sec. Sec.  22.131 and 
22.200 through 22.299. If after the selection process but prior to 
filing a ``long form'' application, a successful bidder decides to 
partition the paging geographic area, the FCC may require and accept 
multiple ``long form'' applications from the consortium members.
    (f) Exclusive right to expand. During the term of a paging 
geographic area authorization, the FCC does not accept, from anyone 
other than the paging geographic area licensee, any major application 
for authorization to operate a facility that would serve unserved area 
within the paging geographic area specified in that paging geographic 
area authorization, on the channel specified in that paging geographic 
area authorization, unless any extension of the interfering contour of 
the proposed facility falls:
    (1) Within the composite interfering contour of another licensee; 
or,
    (2) Into unserved area and the paging geographic area licensee 
consents to such extension.
    (g) Subsequent applications not accepted. During the term of a 
paging geographic area authorization, the FCC does not accept any 
application for authorization relating to a facility that is or would be 
located within the paging geographic area specified in that paging 
geographic area authorization, on the channel specified in that paging 
geographic area authorization, except in the following situations:
    (1) FCC grant of an application authorizing the construction of the 
facility could have a significant environmental effect as defined by 
Sec.  1.1307 of this chapter. See Sec.  22.115(a)(5).
    (2) Specific international coordination procedures are required, 
prior to assignment of a channel to the facility, pursuant to a treaty 
or other agreement between the United States government and the 
government of Canada or Mexico. See Sec.  22.169.
    (3) The paging geographic area licensee or another licensee of a 
system within the paging geographic area applies to assign its 
authorization or for FCC consent to a transfer of control.
    (h) Adjacent geographic area coordination required. Before 
constructing a facility for which the interfering contour (as defined in 
Sec.  22.537 or Sec.  22.567 of this part, as appropriate for the 
channel involved) would extend into another paging geographic area, a 
paging geographic area licensee must obtain the consent of the relevant 
co-channel paging geographic area licensee, if any, into whose area the 
interfering contour would extend. Licensees are expected to cooperate 
fully and in good faith attempt to resolve potential interference

[[Page 55]]

problems before bringing matters to the FCC. In the event that there is 
no co-channel paging geographic area licensee from whom to obtain 
consent in the area into which the interfering contour would extend, the 
facility may be constructed and operated subject to the condition that, 
at such time as the FCC issues a paging geographic area authorization 
for that adjacent geographic area, either consent must be obtained or 
the facility modified or eliminated such that the interfering contour no 
longer extends into the adjacent geographic area.
    (i) Protection of existing service. All facilities constructed and 
operated pursuant to a paging geographic area authorization must provide 
co-channel interference protection in accordance with Sec.  22.537 or 
Sec.  22.567, as appropriate for the channel involved, to all authorized 
co-channel facilities of exclusive licensees within the paging 
geographic area. Non-exclusive licensees on the thirty-five exclusive 
929 MHz channels are not entitled to exclusive status, and will continue 
to operate under the sharing arrangements established with the exclusive 
licensees and other non-exclusive licensees that were in effect prior to 
February 19, 1997. MEA, EA, and nationwide geographic area licensees 
have the right to share with non-exclusive licensees on the thirty-five 
exclusive 929 MHz channels on a non-interfering basis.
    (j) Site location restriction. The transmitting antenna of each 
facility constructed and operated pursuant to a paging geographic area 
authorization must be located within the paging geographic area 
specified in the authorization.
    (k) Coverage requirements. Failure by an MEA or EA licensee to meet 
either the coverage requirements in paragraphs (k)(1) and (k)(2) of this 
section, or alternatively, the substantial service requirement in 
paragraph (k)(3) of this section, will result in automatic termination 
of authorizations for those facilities that were not authorized, 
constructed, and operating at the time the geographic area authorization 
was granted. MEA and EA licensees have the burden of showing when their 
facilities were authorized, constructed, and operating, and should 
retain necessary records of these sites until coverage requirements are 
fulfilled. For the purpose of this paragraph, to ``cover'' area means to 
include geographic area within the composite of the service contour(s) 
determined by the methods of Sec.  22.537 or Sec.  22.567 as appropriate 
for the particular channel involved. Licensees may determine the 
population of geographic areas included within their service contours 
using either the 1990 census or the 2000 census, but not both.
    (1) No later than three years after the initial grant of an MEA or 
EA geographic area authorization, the licensee must construct or 
otherwise acquire and operate sufficient facilities to cover one third 
of the population in the paging geographic area. The licensee must 
notify the FCC at the end of the three-year period pursuant to Sec.  
1.946 of this chapter, either that it has satisfied this requirement or 
that it plans to satisfy the alternative requirement to provide 
substantial service in accordance with paragraph (k)(3) of this section.
    (2) No later than five years after the initial grant of an MEA or EA 
geographic area authorization, the licensee must construct or otherwise 
acquire and operate sufficient facilities to cover two thirds of the 
population in the paging geographic area. The licensee must notify the 
FCC at the end of the five year period pursuant to Sec.  1.946 of this 
chapter, either that it has satisfied this requirement or that it has 
satisfied the alternative requirement to provide substantial service in 
accordance with paragraph (k)(3) of this section.
    (3) As an alternative to the coverage requirements of paragraphs 
(k)(1) and (k)(2) of this section, the paging geographic area licensee 
may demonstrate that, no later than five years after the initial grant 
of its paging geographic area authorization, it provides substantial 
service to the paging geographic area. ``Substantial service'' means 
service that is sound, favorable, and substantially above a level of 
mediocre service that would barely warrant renewal.

Sec.  22.507  Number of transmitters per station.

    This section concerns the number of transmitters licensed under each 
station authorization in the Paging and Radiotelephone Service, other 
than paging geographic area authorizations.
    (a) Operationally related transmitters. Each station must have at 
least one transmitter. There is no limit to the number of transmitters 
that a station may comprise. However, transmitters within a station 
should be operationally related and/or should serve the same general 
geographical area. Operationally related transmitters are those that 
operate together as a system (e.g., trunked systems, simulcast systems), 
rather than independently.
    (b) Split of large systems. The FCC may split wide-area systems into 
two or more stations for administrative convenience. Except for 
nationwide paging and other operationally related transmitters, 
transmitters that are widely separated geographically are not licensed 
under a single authorization.
    (c) Consolidation of separate stations. The FCC may consolidate 
site-specific contiguous authorizations upon request (FCC Form 601) of 
the licensee, if appropriate under paragraph (a) of this section. Paging 
licensees may include remote, stand-alone transmitters under the single 
system-wide authorization, if the remote, stand-alone transmitter is 
linked to the system via a control/repeater facility or by satellite. 
Including a remote, stand-alone transmitter in a system-wide 
authorization does not alter the limitations provided under Sec.  
22.503(f) on entities other than the paging geographic area licensee. In 
the alternative, paging licensees may maintain separate site-specific 
authorizations for stand-alone or remote transmitters. The earliest 
expiration date of the authorizations that make up the single system-
wide authorization will determine the expiration date for the system-
wide authorization. Licensees must file timely renewal applications for 
site-specific authorizations included in a single system-wide 
authorization request until the request is approved. Renewal of the 
system-wide authorization will be subject to Sec.  1.949 of this 
chapter.
    (d) Replacement of site-by-site authorizations with single 
authorization. After a paging geographic area authorization for a 
channel has been issued, the FCC may, on its own motion, replace the 
authorization(s) of any other licensee (for facilities located within 
that paging geographic area on that channel) with a single replacement 
authorization.

64 FR 33784, June 24, 1999]



Sec.  22.509  Procedures for mutually exclusive applications in the
Paging and Radiotelephone Service.

    Mutually exclusive applications in the Paging and Radiotelephone 
Service, including those that are mutually exclusive with applications 
in the Rural Radiotelephone Service, are processed in accordance with 
Sec.  22.131 and with this section.
    (a) Applications in the Paging and Radiotelephone Service may be 
mutually exclusive with applications in the Rural Radiotelephone Service 
if they seek authorization to operate facilities on the same channel in 
the same area, or the technical proposals are otherwise in conflict. See 
Sec.  22.567.
    (b) A modification application in either service filed on the 
earliest filing date may cause all later-filed mutually exclusive

[[Page 57]]

their authorized geographic service area or disaggregate their 
authorized spectrum at any time as of August 23, 1999.
    (a) Application required. Parties seeking approval for partitioning 
and/or disaggregation shall apply for partial assignment of a license 
pursuant to Sec.  1.948 of this chapter.
    (b) Partitioning. In the case of partitioning, requests for 
authorization for partial assignment of a license must include, as 
attachments, a description of the partitioned service area and a 
calculation of the population of the partitioned service area and the 
authorized geographic service area. The partitioned service area shall 
be defined by 120 sets of geographic coordinates at points at every 3 
degrees azimuth from a point within the partitioned service area along 
the partitioned service area boundary unless either an FCC-recognized 
service area is used (e.g., MEA or EA) or county lines are followed. The 
geographical coordinates must be specified in degrees, minutes, and 
seconds to the nearest second latitude and longitude, and must be based 
upon the 1983 North American Datum (NAD83). In the case where FCC-
recognized service areas or county lines are used, applicants need only 
list the specific area(s) through use of FCC designations or county 
names that constitute the partitioned area.

Sec.  22.535  Effective radiated power limits.

    The effective radiated power (ERP) of transmitters operating on the 
channels listed in Sec.  22.531 must not exceed the limits in this 
section.
    (a) Maximum ERP. The ERP must not exceed the applicable limits in 
this paragraph under any circumstances.

------------------------------------------------------------------------

152-159....................................................         1400
931-932....................................................         3500
------------------------------------------------------------------------

    (b) Basic power limit. Except as provided in paragraph (d) of this 
section, the ERP of transmitters on the VHF channels must not exceed 500 
Watts.
    (c) Height-power limit. Except as provided in paragraph (d) of this 
section, the ERP of transmitters on the VHF channels must not exceed the 
amount that would result in an average distance to the service contour 
of 32.2 kilometers (20 miles). The average distance to the service 
contour is calculated by taking the arithmetic mean of the distances 
determined using the procedures specified in Sec.  22.537 for the eight 
cardinal radial directions, excluding cardinal radial directions for 
which 90% or more of the distance so calculated is over water.
    (d) Encompassed interfering contour areas. Transmitters are exempt 
from the basic power and height-power limits of this section if the area 
within their interfering contours is totally encompassed by the 
interfering contours of operating co-channel base transmitters 
controlled by the same licensee. For the purpose of this paragraph, 
operating transmitters are authorized transmitters that are providing 
service to subscribers.
    (e) Adjacent channel protection. The ERP of transmitters must not 
exceed 500 Watts if they:

[[Page 60]]

    (1) Transmit on a channel in the 152-159 MHz frequency range and are 
located less than 5 kilometers (3.1 miles) from any station licensed in 
the Private Radio Services that receives on an adjacent channel; or,
    (2) Transmit on channel 158.10 or 158.70 MHz and are located less 
than 5 kilometers (3.1 miles) from any station licensed in the Public 
Mobile Services that receives on either of the following adjacent 
channels: 158.07 MHz or 158.67 MHz.
    (f) Signal boosters. The effective radiated power of signal boosters 
must not exceed 5 watts ERP under any normal operating condition.

Sec.  22.537  Technical channel assignment criteria.

    The rules in this section establish technical assignment criteria 
for the channels listed in Sec.  22.531. These criteria permit channel 
assignments to be made in a manner such that reception by public paging 
receivers of signals from base transmitters, within the service area of 
such base transmitters, is protected from interference caused by the 
operation of independent co-channel base transmitters.
    (a) Contour overlap. The FCC may grant an application requesting 
assignment of a channel to a proposed base transmitter only if:
    (1) The interfering contour of the proposed transmitter does not 
overlap the service contour of any protected co-channel transmitter 
controlled by a carrier other than the applicant, unless that carrier 
has agreed in writing to accept any interference that may result from 
operation of the proposed transmitter; and,
    (2) The service contour of the proposed transmitter does not overlap 
the interfering contour of any protected co-channel transmitter 
controlled by a carrier other than the applicant, unless the applicant 
agrees to accept any interference that may result from operation of the 
protected co-channel transmitter; and,
    (3) The area and/or population to which service would be provided by 
the proposed transmitter is substantial, and service gained would exceed 
that lost as a result of agreements to accept interference.
    (b) Protected transmitter. For the purposes of this section, 
protected transmitters are authorized transmitters for which there is a 
current FCC public record and transmitters proposed in prior-filed 
pending applications.
    (c) VHF service contour. For paging stations transmitting on the VHF 
channels, the distance from the transmitting antenna to the service 
contour along each cardinal radial is calculated as follows:

d = 1.243 x h\0.40\ x p\0.20\

where d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    (1) Whenever the actual HAAT is less than 30 meters (98 feet), 30 
must be used as the value for h in the above formula.
    (2) The value used for p in the above formula must not be less than 
27 dB less than the maximum ERP in any direction or 0.1 Watt, whichever 
is more.
    (3) The distance from the transmitting antenna to the service 
contour along any radial other than the eight cardinal radials is 
routinely calculated by linear interpolation of distance as a function 
of angle. However, in resolving petitions to deny, the FCC may calculate 
the distance to the service contour using the formula in paragraph (c) 
of this section with actual HAAT and ERP data for the inter-station 
radial and additional radials above and below the inter-station radial 
at 2.5[deg] intervals.
    (d) VHF interfering contour. For paging stations transmitting on the 
VHF channels, the distance from the transmitting antenna to the 
interfering contour along each cardinal radial is calculated as follows:

d = 6.509 x h\0.28\ x p\0.17\

where d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    (1) Whenever the actual HAAT is less than 30 meters (98 feet), 30 
must be used as the value for h in the above formula.
    (2) The value used for p in the above formula must not be less than 
27 dB

[[Page 61]]

less than the maximum ERP in any direction or 0.1 Watt, whichever is 
more.
    (3) The distance from the transmitting antenna to the interfering 
contour along any radial other than the eight cardinal radials is 
routinely calculated by linear interpolation of distance as a function 
of angle. In resolving petitions to deny, however, the FCC may calculate 
the distance to the interfering contour using the formula in paragraph 
(d) of this section with actual HAAT and ERP data for the inter-station 
radial and additional radials above and below the inter-station radial 
at 2.5[deg] intervals.
    (e) 931 MHz service contour. For paging stations transmitting on the 
931 MHz channels, the service contour is a circle, centered on the 
transmitting antenna, with a radius determined from Table E-1 of this 
section.

    (g) In-building radiation systems. The locations of in-building 
radiation systems must be within the service contour(s) of the 
licensee's authorized transmitter(s) on the same channel. In-building 
radiation systems are not protected facilities, and therefore do not 
have service or interfering contours.
    (h) Signal boosters on 931 MHz channels. For the purpose of 
compliance with Sec.  22.165 and notwithstanding paragraphs (e) and (f) 
of this section, signal boosters operating on the 931 MHz channels with 
an antenna HAAT not exceeding 30 meters (98 feet) are deemed to have as 
a service contour a

Sec.  22.559  Paging application requirements.

    In addition to information required by subparts B and D and Sec.  
22.529, applications for authorization to operate a paging transmitter 
on the channels listed in Sec.  22.531, other than applications for a 
paging geographic area authorization, must contain the applicable 
supplementary information described in this section.
    (a) Interference exhibit. Except as provided in paragraph (b) of 
this section, an exhibit demonstrating compliance with Sec.  22.537 with 
regard to protected transmitters is required for applications to operate 
a transmitter on the VHF channels. This exhibit must:
    (1) Identify each protected transmitter located within 109 
kilometers (68 miles) of the proposed transmitter in directions in which 
the distance to the interfering contour is 76.5 kilometers (47.5 miles) 
or less, and within 178 kilometers (111 miles) of the proposed 
transmitter in directions in which the distance to the interfering 
contour exceeds 76.5 kilometers (47.5 miles).
    (2) For each protected transmitter identified, show the results of 
distance calculations indicating that there would be no overlap of 
service and interfering contours, or alternatively, indicate that the 
licensee of or applicant for the protected transmitter and/or the 
applicant, as required, have agreed in writing to accept any 
interference resulting from operation of the proposed transmitter.
    (b) Encompassment exhibit. An exhibit showing that the area within 
the interfering contour of the proposed transmitter would be totally 
encompassed by interfering contours of operating co-channel base 
transmitters controlled by the applicant is required for applications to 
operate a transmitter with ERP exceeding the basic power and height-
power limits of Sec.  22.535. For VHF transmitters, this encompassment 
exhibit may substitute for the interference exhibit required in 
paragraph (a) of this section.

                   One-way or Two-way Mobile Operation



Sec.  22.561  Channels for one-way or two-way mobile operation.

    The following channels are allocated for paired assignment to 
transmitters that provide (or support other transmitters that provide) 
one-way or two-way public land mobile service, either individually or 
collectively under a paging geographic area authorization. The paging 
geographic areas used for these channels are the EAs (see Sec.  
22.503(b)(3)). These channels may be assigned for use by mobile or base 
transmitters as indicated, and or by fixed transmitters (including 
control, repeater or other fixed transmitters). The mobile channels may 
also be assigned for use by base or fixed transmitters under certain 
circumstances (see Sec.  22.567(h)). Unless otherwise indicated, all 
channels have a bandwidth of 20 kHz and are designated by their center 
frequencies in MegaHertz.

Sec.  22.565  Transmitting power limits.

    The transmitting power of base, mobile and fixed transmitters 
operating on the channels listed in Sec.  22.561 must not exceed the 
limits in this section.
    (a) Maximum ERP. The effective radiated power (ERP) of base and 
fixed transmitters must not exceed the applicable limits in this 
paragraph under any circumstances.

------------------------------------------------------------------------
                                                             Maximum ERP
                   Frequency range (MHz)                       (watts)

157-159....................................................          150
454-455....................................................         3500
459-460....................................................          150
------------------------------------------------------------------------

    (b) Basic power limit. Except as provided in paragraph (d) of this 
section, the ERP of base transmitters must not exceed 500 Watts.
    (c) Height-power limits. Except as provided in paragraph (d) of this 
section, the ERP of base transmitters must not exceed the amount that 
would result in an average distance to the service contour of 41.6 
kilometers (26 miles) for VHF channels or 30.7 kilometers (19 miles) for 
UHF channels. The average distance to the service contour is calculated 
by taking the arithmetic mean of the distances determined using the 
procedures specified in Sec.  22.567 for the eight cardinal radial 
directions, excluding cardinal radial directions for which 90% or more 
of the distance so calculated is over water.
    (d) Encompassed interfering contour areas. Base transmitters are 
exempt from the basic power and height-power limits of this section if 
the area within their interfering contours is totally encompassed by the 
interfering contours of operating co-channel based transmitters 
controlled by the same licensee. For the purpose of this paragraph, 
operating transmitters are authorized transmitters that are providing 
service to subscribers.
    (e) Adjacent channel protection. The ERP of base and fixed 
transmitters must not exceed 500 Watts if they transmit on channel 
454.025 MHz and are located less than 7 kilometers (4.3 miles) from any 
Private Radio Services station receiving on adjacent channel 454.0000 
MHz.
    (f) Mobile transmitters. The transmitter output power of mobile 
transmitters must not exceed 60 watts.

[59 FR 59507, Nov. 17, 1994, as amended at 70 FR 19309, Apr. 13, 2005]



Sec.  22.567  Technical channel assignment criteria.

    The rules in this section establish technical assignment criteria 
for the channels listed in Sec.  22.561. The criteria in paragraphs (a) 
through (f) of this section permit channel assignments to be made in a 
manner such that reception by public mobile receivers of signals from 
base transmitters, within the service area of such base transmitters, is 
protected from interference caused by the operation of independent co-
channel base and fixed transmitters in the Paging and Radiotelephone 
Service and central office stations, including Basic Exchange Telephone 
Radio Systems (BETRS), in the Rural Radiotelephone Service. Additional 
criteria in paragraph (g) of this section permit channel assignments to 
be made in a manner such that BETRS communications are protected from 
interference caused by the operation of independent co-channel base and 
fixed transmitters in the Paging and Radiotelephone Service and other 
central office stations in the Rural Radiotelephone Service. Separate 
criteria in paragraph (h) of this section apply only to assignment of 
the channels designated in Sec.  22.561 as mobile channels to base and 
fixed transmitters, and permit these channel assignments to be made in a 
manner such that reception by public base and fixed receivers of signals 
from associated mobile and fixed transmitters is protected from 
interference caused by the operation of independent co-channel base and 
fixed transmitters.
    (a) Contour overlap. The FCC may grant an application requesting 
assignment of a channel to a proposed base, fixed or central office 
station transmitter only if:
    (1) The interfering contour of the proposed transmitter does not 
overlap the service contour of any protected co-channel transmitter 
controlled by a carrier other than the applicant, unless that carrier 
has agreed in writing to

[[Page 64]]

accept any interference that may result from operation of the proposed 
transmitter; and
    (2) The service contour of the proposed transmitter does not overlap 
the interfering contour of any protected co-channel transmitter 
controlled by a carrier other than the applicant, unless the application 
contains a statement that the applicant agrees to accept any 
interference that may result from operation of the protected co-channel 
transmitter; and
    (3) The area and/or population to which service would be provided by 
the proposed transmitter is substantial, and service gained would exceed 
that lost as a result of agreements to accept interference.
    (b) Protected transmitter. For the purposes of this section, 
protected transmitters are authorized transmitters for which there is a 
current FCC public record and transmitters proposed in prior-filed 
pending applications, in the Paging and Radiotelephone Service and the 
Rural Radiotelephone Service.
    (c) VHF service contour. For base stations transmitting on the VHF 
channels, the radial distance from the transmitting antenna to the 
service contour along each cardinal radial is calculated as follows:

d = 1.609 x h\0.40\ x p\0.20\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    (1) Whenever the actual HAAT is less than 30 meters (98 feet), 30 
must be used as the value for h in the above formula.
    (2) The value used for p in the above formula must not be less than 
27 dB less than the maximum ERP in any direction, or 0.1 Watt, whichever 
is more.
    (3) The distance from the transmitting antenna to the service 
contour along any radial other than the eight cardinal radials is 
routinely calculated by linear interpolation of distance as a function 
of angle. However, in resolving petitions to deny, the FCC may calculate 
the distance to the service contour using the formula in paragraph (c) 
of this section with actual HAAT and ERP data for the inter-station 
radial and additional radials above and below the inter-station radial 
at 2.5[deg] intervals.
    (d) VHF interfering contour. For base and fixed stations 
transmitting on the VHF channels, the radial distance from the 
transmitting antenna to the interfering contour along each cardinal 
radial is calculated as follows:
    (1) If the radial antenna HAAT is less than 150 meters:

d = 8.577 x h\0.24\ x p\0.19\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    Whenever the actual HAAT is less than 30 meters (98 feet), 30 must 
be used as the value for h in the above formula.
    (2) If the radial antenna HAAT is 150 meters or more:

d = 12.306 x h\0.23\ x p\0.14\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    (3) The value used for p in the above formulas must not be less than 
27 dB less than the maximum ERP in any direction, or 0.1 Watt, whichever 
is more.
    (4) The distance from the transmitting antenna to the interfering 
contour along any radial other than the eight cardinal radials is 
routinely calculated by linear interpolation of distance as a function 
of angle. However, in resolving petitions to deny, the FCC may calculate 
the distance to the interfering contour using the appropriate formula in 
paragraph (d) of this section with actual HAAT and ERP data for the 
inter-station radial and additional radials above and below the inter-
station radial at 2.5[deg] intervals.
    (e) UHF service contour. For base stations transmitting on the UHF 
channels, the radial distance from the transmitting antenna to the 
service contour along each cardinal radial is calculated as follows:

d = 1.726 x h\0.35\ x p\0.18\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts


[[Page 65]]


    (1) Whenever the actual HAAT is less than 30 meters (98 feet), 30 
must be used as the value for h in the above formula.
    (2) The value used for p in the above formula must not be less than 
27 dB less than the maximum ERP in any direction, or 0.1 Watt, whichever 
is more.
    (3) The distance from the transmitting antenna to the service 
contour along any radial other than the eight cardinal radials is 
routinely calculated by linear interpolation of distance as a function 
of angle. However, in resolving petitions to deny, the FCC may calculate 
the distance to the service contour using the formula in paragraph (e) 
of this section with actual HAAT and ERP data for the inter-station 
radial and addition radials above and below the below the inter-station 
radial at 2.5[deg] intervals.
    (f) UHF interfering contour. For base and fixed stations 
transmitting on the UHF channels, the radial distance from the 
transmitting antenna to the interfering contour along each cardinal 
radial is calculated as follows:
    (1) If the radial antenna HAAT is less than 150 meters:

d = 9.471 x h\0.23\ x p\0.15\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    Whenever the actual HAAT is less than 30 meters (98 feet), 30 must 
be used as the value for h in the above formula.
    (2) If the radial antenna HAAT is 150 meters or more:

d = 6.336 x h\0.31\ x p\0.15\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    (3) The value used for p in the above formula must not be less than 
27 dB less than the maximum ERP in any direction, or 0.1 Watt, whichever 
is more.
    (4) The distance from the transmitting antenna to the interfering 
contour along any radial other than the eight cardinal radials is 
routinely calculated by linear interpolation of distance as a function 
of angle. However, in resolving petitions to deny, the FCC may calculate 
the distance to the interfering contour using the appropriate formula in 
paragraph (f) of this section with actual HAAT and ERP data for the 
inter-station radial and additional radials above and below the inter-
station radial at 2.5[deg] intervals.
    (g) Protection for BETRS. In applying the provisions of paragraph 
(a) of this section, if either or both of the transmitters involved is a 
BETRS central office station, the following contour substitutions must 
be used:
    (1) The service contour of the BETRS central office station(s) is a 
circle, centered on the central office station antenna, with a radius of 
40 kilometers (25 miles).
    (2) The interfering contour of any station of any type, when 
determining whether it would overlap the service contour of a BETRS 
central office station, is calculated as follows:

d = 36.364 x h\0.2\ x p\0.1\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    Whenever the actual HAAT is less than 30 meters (98 feet), 30 must 
be used as the value for h in the above formula. The value used for p in 
the above formula must not be less than 27 dB less than the maximum ERP 
in any direction, or 0.1 Watt, whichever is more.
    (h) Assignment of mobile channels to base or fixed transmitters. 
Mobile channels may be assigned to base or fixed transmitters if the 
following criteria are met:
    (1) The paired base channel, as designated in Sec.  22.561, is 
assigned to base transmitters in the same geographical area operated by 
the same licensee.
    (2) The authorization is granted subject to the condition that no 
interference be caused to fixed receivers in use on or prior to the date 
of the grant.



Sec.  22.571  Responsibility for mobile stations.

    Mobile stations that are subscribers in good standing to a two-way 
service in the Paging and Radiotelephone Service, when receiving service 
from that station, are considered to be operating under the 
authorization of that station. Licensees are responsible for

[[Page 66]]

exercising effective operational control over mobile stations receiving 
service through their stations. Mobile stations that are subscribers in 
good standing to a two-way service in the Paging and Radiotelephone 
Service, while receiving service from a different station, are 
considered to be operating under the authorization of such different 
station. The licensee of such different station is responsible, during 
such temporary period, for exercising effective operational control over 
such mobile stations as if they were subscribers to it.



Sec.  22.573  Use of base transmitters as repeaters.

    As an additional function, base transmitters may be used as 
repeaters. Licensees must be able to turn the base transmitter on or off 
from the control point regardless of whether a subscriber-operated 
transmitter is transmitting.



Sec.  22.575  Use of mobile channel for remote control of station functions.

    Carriers may remotely control station functions (e.g. shut down or 
reactivate base transmitters, turn aviation obstruction warning lights 
on or off, etc.) using a control transmitter operating on a mobile 
channel, subject to the conditions in this section and in Sec.  
22.567(h).
    (a) The control transmitter must be capable of overriding 
transmissions from subscriber-operated transmitters if necessary. 
Subscriber-operated transmitters must not be capable of being used to 
deliberately or accidentally prevent the licensee from controlling the 
station.
    (b) The licensee must implement measures designed to prevent station 
functions from being controlled by persons not authorized by the 
licensee to control the station.
    (c) The control transmitter location must be within the composite 
service contour of the licensee's authorized station on the paired base 
channel.



Sec.  22.579  Operation of mobile transmitters across U.S.-Canada border.

    Mobile stations licensed by Canada may receive two-way service while 
in the United States from stations licensed under this part, after 
authorization has been granted by the FCC. Mobile stations that normally 
operate under the authority of base stations licensed under this part 
may receive two-way service while in Canada from stations licensed under 
this part or by Canada, upon authorization by Canada.



Sec.  22.589  One-way or two-way application requirements.

    In addition to information required by subparts B and D and Sec.  
22.529, applications for authorization to operate a paging transmitter 
on the channels listed in Sec.  22.531, other than applications for a 
paging geographic area authorization, must contain the applicable 
supplementary information described in this section.
    (a) Interference exhibit. Except as provided in paragraph (b) of 
this section, an exhibit demonstrating compliance with Sec.  22.567 with 
regard to protected transmitters is required. This exhibit must:
    (1) For UHF channels, identify each protected transmitter located 
within 108 kilometers (67 miles) of the proposed transmitter in 
directions in which the distance to the interfering contour is 76.4 
kilometers (47.5 miles) or less, and within 178 kilometers (111 miles) 
of the proposed transmitter in directions in which the distance to the 
interfering contour exceeds 76.4 kilometers (47.5 miles); and identify 
each protected Basic Exchange Telephone Radio System central office 
transmitter in the Rural Radiotelephone Service within 231 kilometers 
(144 miles),
    (2) For VHF channels, identify each protected transmitter located 
within 135 kilometers (84 miles) of the proposed transmitter in 
directions in which the distance to the interfering contour is 93.3 
kilometers (58 miles) or less, and within 178 kilometers (111 miles) of 
the proposed transmitter in directions in which the distance to the 
interfering contour exceeds 93.3 kilometers (58 miles).
    (3) For each protected transmitter identified, show the results of 
distance calculations indicating that there would be no overlap of 
service and interfering contours, or alternatively, indicate that the 
licensee of or applicant for the protected transmitter and/

[[Page 67]]

or the applicant, as required, have agreed in writing to accept any 
interference resulting from operation of the proposed transmitter.
    (b) Encompassment exhibit. An exhibit showing that the area within 
the interfering contour of the proposed transmitter would be totally 
encompassed by interfering contours of operating co-channel base 
transmitters controlled by the applicant is required for applications to 
operate a transmitter with ERP exceeding the basic power and height-
power limits of Sec.  22.565. This encompassment exhibit may substitute 
for the interference exhibit required in paragraph (a) of this section.

                        Point-to-Point Operation



Sec.  22.591  Channels for point-to-point operation.

    The following channels are allocated for assignment to fixed 
transmitters that support other transmitters that provide public mobile 
service. Unless otherwise indicated, all channels have a bandwidth of 20 
kHz and are designated by their center frequencies in MegaHertz.

configurations. The 72-76 MHz channels are also allocated for assignment 
in the Private Radio Services (see part 90 of this chapter).
    (b) [Reserved]
    (c) Channels in the frequency ranges 488.250-490.750 and 491.250-

FR 19309, Apr. 13, 2005; 78 FR 25174, Apr. 29, 2013]



Sec.  22.593  Effective radiated power limits.

    The effective radiated power of fixed stations operating on the 
channels listed in Sec.  22.591 must not exceed 150 Watts. The 
equivalent isotropically radiated power of existing fixed microwave 
stations (2110-2130 and 2160-2180 MHz) licensed under this part 
(pursuant to former rules) must not exceed the applicable limits set 
forth in Sec.  101.113 of this chapter.

[70 FR 19309, Apr. 13, 2005]



Sec.  22.601  Existing microwave stations licensed under this part.

    Existing microwave stations (2110-2130 and 2160-2180 MHz) licensed 
under this part (pursuant to former rules) are subject to the transition 
rules in Sec.  22.602. No new microwave systems will be authorized under 
this part.
    (a) Coordination required. Before filing applications for authority 
to modify existing stations on these channels or major amendments to 
such applications, carriers must coordinate the planned channel usage, 
using the procedure outlined in Sec.  22.150, with affected parties in 
this radio service and the Point-to-Point Microwave Service and the 
Multipoint Distribution Service. Affected parties are licensees and 
other applicants with previously filed pending applications whose 
stations could affect or be affected by the proposed

[[Page 68]]

modification of the existing station in terms of interference.
    (b) System parameters. In designing a system modification, the 
applicant must select sites, equipment and channels that will avoid 
harmful interference to other users. All parties must cooperate fully 
and make reasonable efforts to resolve technical problems and conflicts 
that may inhibit the most effective and efficient use of the radio 
spectrum; however, a party receiving notification is not obligated to 
suggest changes or re-design a proposal in cases involving conflicts. 
The applicant must identify in the application all parties with which 
the technical proposal was coordinated. In the event that technical 
problems are not resolved or if an affected party does not respond to 
coordination efforts within 30 days after notification, an explanation 
must be contained in the application. Where technical conflicts are 
resolved by an agreement between the parties that requires special 
procedures to reduce the likelihood of harmful interference (such as the 
use of artificial site shielding), or would result in a reduction of 
quality or capacity of either system, the details thereof must be 
contained in the application.
    (c) Bandwidth. Applicants must request the minimum emission 
bandwidth necessary. The FCC does not authorize bandwidths larger than 
800 kHz under this part.

[59 FR 59507, Nov. 17, 1994, as amended at 70 FR 19309, Apr. 13, 2005]



Sec.  22.602  Transition of the 2110-2130 and 2160-2180 MHz channels to
emerging technologies.

    The 2110-2130 and 2160-2180 MHz microwave channels formerly listed 
in Sec.  22.591 have been re-allocated for use by emerging technologies 
(ET) services. No new systems will be authorized under this part. The 
rules in this section provide for a transition period during which 
existing Paging and Radiotelephone Service (PARS) licensees using these 
channels may relocate operations to other media or to other fixed 
channels, including those in other microwave bands. For PARS licensees 
relocating operations to other microwave bands, authorization must be 
obtained under part 101 of this chapter.
    (a) Licensees proposing to implement ET services may negotiate with 
PARS licensees authorized to use these channels, for the purpose of 
agreeing to terms under which the PARS licensees would--
    (1) Relocate their operations to other fixed microwave bands or 
other media, or alternatively,
    (2) Accept a sharing arrangement with the ET licensee that may 
result in an otherwise impermissible level of interference to the PARS 
operations.
    (b) [Reserved]
    (c) Relocation of fixed microwave licensees in the 2110-2130 MHz and 
2160-2180 MHz bands will be subject to mandatory negotiations only. A 
separate mandatory negotiation period will commence for each fixed 
microwave licensee when an ET licensee informs that fixed microwave 
licensee in writing of its desire to negotiate. Mandatory negotiation 
periods are defined as follows:
    (1) Non-public safety incumbents will have a two-year mandatory 
negotiation period; and
    (2) Public safety incumbents will have a three-year mandatory 
negotiation period.
    (d) The mandatory negotiation period is triggered at the option of 
the ET licensee. Once mandatory negotiations have begun, a PARS licensee 
may not refuse to negotiate and all parties are required to negotiate in 
good faith. Good faith requires each party to provide information to the 
other that is reasonably necessary to facilitate the relocation process. 
In evaluating claims that a party has not negotiated in good faith, the 
FCC will consider, inter alia, the following factors:
    (1) Whether the ET licensee has made a bona fide offer to relocate 
the PARS licensee to comparable facilities in accordance with Section 
101.75(b) of this chapter;
    (2) If the PARS licensee has demanded a premium, the type of premium 
requested (e.g., whether the premium is directly related to relocation, 
such as system-wide relocations and analog-to-digital conversions, 
versus other types of premiums), and whether the value of the premium as 
compared

[[Page 69]]

to the cost of providing comparable facilities is disproportionate 
(i.e., whether there is a lack of proportion or relation between the 
two);
    (3) What steps the parties have taken to determine the actual cost 
of relocation to comparable facilities;
    (4) Whether either party has withheld information requested by the 
other party that is necessary to estimate relocation costs or to 
facilitate the relocation process. Any party alleging a violation of our 
good faith requirement must attach an independent estimate of the 
relocation costs in question to any documentation filed with the 
Commission in support of its claim. An independent cost estimate must 
include a specification for the comparable facility and a statement of 
the costs associated with providing that facility to the incumbent 
licensee.
    (e) Involuntary period. After the end of the mandatory negotiation 
period, ET licensees may initiate involuntary relocation procedures 
under the Commission's rules. ET licensees are obligated to pay to 
relocate only the specific microwave links to which their systems pose 
an interference problem. Under involuntary relocation, a PARS licensee 
is required to relocate, provided that:
    (1) The ET applicant, provider, licensee or representative 
guarantees payment of relocation costs, including all engineering, 
equipment, site and FCC fees, as well as any legitimate and prudent 
transaction expenses incurred by the PARS licensee that are directly 
attributable to an involuntary relocation, subject to a cap of two 
percent of the hard costs involved. Hard costs are defined as the actual 
costs associated with providing a replacement system, such as equipment 
and engineering expenses. ET licensees are not required to pay PARS 
licensees for internal resources devoted to the relocation process. ET 
licensees are not required to pay for transaction costs incurred by PARS 
licensees during the voluntary or mandatory periods once the involuntary 
period is initiated or for fees that cannot be legitimately tied to the 
provision of comparable facilities;
    (2) The ET applicant, provider, licensee or representative completes 
all activities necessary for implementing the replacement facilities, 
including engineering and cost analysis of the relocation procedure and, 
if radio facilities are involved, identifying and obtaining, on the 
incumbents behalf, new channels and frequency coordination; and,
    (3) The ET applicant, provider, licensee or representative builds 
the replacement system and tests it for comparability with the existing 
2 GHz system.
    (f) Comparable Facilities. The replacement system provided to an 
incumbent during an involuntary relocation must be at least equivalent 
to the existing PARS system with respect to the following three factors:
    (1) Throughput. Communications throughput is the amount of 
information transferred within a system in a given amount of time. If 
analog facilities are being replaced with analog, the ET licensee is 
required to provide the PARS licensee with an equivalent number of 4 kHz 
voice channels. If digital facilities are being replaced with digital, 
the ET licensee must provide the PARS licensee with equivalent data 
loading bits per second (bps). ET licensees must provide PARS licensees 
with enough throughput to satisfy the PARS licensee's system use at the 
time of relocation, not match the total capacity of the PARS system.
    (2) Reliability. System reliability is the degree to which 
information is transferred accurately within a system. ET licensees must 
provide PARS licensees with reliability equal to the overall reliability 
of their system. For digital data systems, reliability is measured by 
the percent of time the bit error rate (BER) exceeds a desired value, 
and for analog or digital voice transmissions, it is measured by the 
percent of time that audio signal quality meets an established 
threshold. If an analog voice system is replaced with a digital voice 
system, only the resulting frequency response, harmonic distortion, 
signal-to-noise ratio and its reliability will be considered in 
determining comparable reliability.
    (3) Operating Costs. Operating costs are the cost to operate and 
maintain the PARS system. ET licensees must compensate PARS licensees 
for any increased recurring costs associated with

[[Page 70]]

the replacement facilities (e.g. additional rental payments, increased 
utility fees) for five years after relocation. ET licensees may satisfy 
this obligation by making a lump-sum payment based on present value 
using current interest rates. Additionally, the maintenance costs to the 
PARS licensee must be equivalent to the 2 GHz system in order for the 
replacement system to be considered comparable.
    (g) The PARS licensee is not required to relocate until the 
alternative facilities are available to it for a reasonable time to make 
adjustments, determine comparability, and ensure a seamless handoff.
    (h) [Reserved]
    (i) After April 25, 1996, all major modifications and extensions to 
existing PARS systems operating on channels in the 2110-2130 and 2160-
2180 MHz bands will be authorized on a secondary basis to future ET 
operations. All other modifications will render the modified PARS 
license secondary to future ET operations unless the incumbent 
affirmatively justifies primary status and the incumbent PARS licensee 
establishes that the modification would not add to the relocation costs 
of ET licensees. Incumbent PARS licensees will maintain primary status 
for the following technical changes:
    (1) Decreases in power;
    (2) Minor changes (increases or decreases) in antenna height;
    (3) Minor location changes (up to two seconds);
    (4) Any data correction which does not involve a change in the 
location of an existing facility;
    (5) Reductions in authorized bandwidth;
    (6) Minor changes (increases or decreases) in structure height;
    (7) Changes (increases or decreases) in ground elevation that do not 
affect centerline height;
    (8) Minor equipment changes.
    (j) Sunset. PARS licensees will maintain primary status in the 2110-
2130 MHz and 2160-2180 MHz bands unless and until an ET licensee 
requires use of the spectrum. ET licensees are not required to pay 
relocation costs after the relocation rules sunset (i.e., for the 2110-
2130 MHz and 2160-2180 MHz bands, ten years after the first ET license 
is issued in the respective band). Once the relocation rules sunset, an 
ET licensee may require the incumbent to cease operations, provided that 
the ET licensee intends to turn on a system within interference range of 
the incumbent, as determined by TIA TSB 10-F or any standard successor. 
ET licensee notification to the affected PARS licensee must be in 
writing and must provide the incumbent with no less than six months to 
vacate the spectrum. After the six-month notice period has expired, the 
PARS licensee must turn its license back into the Commission, unless the 
parties have entered into an agreement which allows the PARS licensee to 
continue to operate on a mutually agreed upon basis. If the parties 
cannot agree on a schedule or an alternative arrangement, requests for 
extension will be accepted and reviewed on a case-by-case basis. The 
Commission will grant such extensions only if the incumbent can 
demonstrate that:
    (1) It cannot relocate within the six-month period (e.g., because no 
alternative spectrum or other reasonable option is available), and;
    (2) The public interest would be harmed if the incumbent is forced 
to terminate operations (e.g., if public safety communications services 
would be disrupted).
    (k) Reimbursement and relocation expenses in the 2110-2130 MHz and 
2160-2180 MHz bands. Whenever an ET licensee in the 2110-2130 MHz and 
2160-2180 MHz band relocates a paired PARS link with one path in the 
2110-2130 MHz band and the paired path in the 2160-2180 MHz band, the ET 
license will be entitled to reimbursement pursuant to the procedures 
described in Sec. Sec.  27.1160 through 27.1174 of this chapter.

[61 FR 29689, June 12, 1996, as amended at 70 FR 19309, Apr. 13, 2005; 
71 FR 29834, May 24, 2006]



Sec.  22.603  488-494 MHz fixed service in Hawaii.

    Before filing applications for authorization of inter-island control 
and/or repeater stations, applicants must coordinate the planned channel 
usage with existing licensees and other applicants with previously filed 
applications, using the procedure outlined in Sec.  22.150. Applicants 
and licensees shall

[[Page 71]]

cooperate fully and make reasonable efforts to resolve any channel usage 
conflicts. In situations where technical solutions to such conflicts 
cannot be devised, the FCC may select a channel or channels to assign or 
may designate the application(s) for hearing. To be acceptable for 
filing, applications and major technical amendments must contain a 
certification that coordination has been completed and an exhibit 
listing the name(s) of the licensees and applicants with which the 
planned channel usage has been coordinated.

                      Point-to-Multipoint Operation



Sec.  22.621  Channels for point-to-multipoint operation.

    The following channels are allocated for assignment to transmitters 
utilized within point-to-multipoint systems that support transmitters 
that provide public mobile service. Unless otherwise indicated, all 
channels have a bandwidth of 20 kHz and are designated by their center 
frequencies in MegaHertz. No new licenses will be issued for any 900 MHz 
frequencies in this section. See part 101, subpart O of this chapter for 
treatment of incumbents and for new licensing procedures. Incumbents 
under part 22 are subject to the restrictions of part 101, subpart O of 
this chapter but may make permissible modifications, transfers, 
assignments, or renew their licenses using procedures, forms, fees, and 
filing requirements of part 22.

Sec.  22.623  System configuration.

    This section requires a minimum configuration for point-to-
multipoint systems using the channels listed in Sec.  22.621.
    (a) 928-960 MHz. The channels may be assigned, individually or 
paired, only to fixed transmitters in a system that controls at least 
four public mobile base transmitters that transmit on the same channel. 
If a 932-933 MHz channel and a 941-942 MHz channel are assigned as a 
pair, the 941-942 MHz channel must be assigned only to control 
transmitters; the 932-933 MHz channel may be assigned to control or 
fixed relay transmitters.
    (b) 470-512 MHz. These channels may be assigned only individually 
(unpaired), to control transmitters that

[[Page 73]]

directly control at least four public mobile base transmitters that 
transmit on the same channel. Fixed relay transmitters are not 
authorized.
    (c) Selection and assignment. The FCC selects and assigns a channel 
when granting applications for authorization to operate a new station to 
transmit in the 470-512, 932-933 and 941-942 MHz frequency ranges. 
Applicants having a preference may request the assignment of a specific 
channel or channel pair, but the FCC may in some cases be unable to 
satisfy such requests.



Sec.  22.625  Transmitter locations.

    This section governs where point-to-multipoint transmitters on the 
channels listed in Sec.  22.621 may be located.
    (a) 928-960 MHz. In this frequency range, the required minimum 
distance separation between co-channel fixed transmitters is 113 
kilometers (70 miles).
    (b) 470-512 MHz. The purpose of the rule in paragraph (b)(1) of this 
section is to define the areas in which the 470-512 MHz channels are 
allocated for public mobile use. The purpose of the rules in paragraphs 
(b)(2) and (b)(3) of this section is to reduce the likelihood that 
interference to television reception from public mobile operations on 
these channels will occur.
    (1) Control transmitter locations. Control transmitter locations 
must be within 80 kilometers (50 miles) of the designated locations in 
this paragraph.

    (2) Protection from intermodulation interference. Control 
transmitter locations must be at least 1.6 kilometers (1 mile) from the 
main transmitter locations of all TV stations transmitting on TV 
channels separated by 2, 3, 4, 5, 7, or 8 TV channels from the TV 
channel containing the frequencies on which the control station will 
transmit. This requirement is intended to reduce the likelihood of 
intermodulation interference.
    (3) Co-channel protection from control transmitters with high 
antennas. This paragraph applies only to control transmitters that 
utilize an antenna height of more than 152 meters (500 feet) above 
average terrain. The distance between the location of such a control 
transmitter and the applicable protected TV station location specified 
in this paragraph must equal or exceed the sum of the distance from the 
control transmitter location to the radio horizon in the direction of 
the specified location and 89 kilometers (55 miles--representing the 
distance from the main transmitter location of the TV station to its 
Grade B contour in the direction of the control transmitter). The 
protected TV station locations in this paragraph are the locations of 
record as of September 1974, and these do not change even though the TV 
stations may have been subsequently relocated.
    (i) The protected TV station locations are as follows:

Sec.  22.653  Eligibility.

    Only licensees already authorized to provide trunked mobile service 
or their successors in interest are eligible to apply for additional use 
of these channels for trunked mobile service, and then only in the urban 
areas already authorized.



Sec.  22.657  Transmitter locations.

    The purpose of the rules in paragraphs (a) and (b) of this section 
is to define the areas in which the 470-512 MHz channels are allocated 
for public mobile use. The purpose of the rules in paragraphs (c) 
through (f) of this section is to reduce the likelihood that 
interference to television reception from public mobile operations on 
these channels will occur. The protected TV station locations specified 
in paragraphs (d), (e)(1) and (f) of this section are the locations of 
record as of September 1974, and these do not change even though the TV 
stations may have been subsequently relocated.

[[Page 77]]

    (a) Base transmitter locations. Base transmitter locations must be 
within 80 kilometers (50 miles) of the designated locations in this 
paragraph. Mobile transmitters must not be operated at locations more 
than 129 kilometers (80 miles) from the designated locations in this 
paragraph. Note: All coordinates are referenced to North American Datum 
1983 (NAD83).

    (b) Mobile area of operation. Mobile transmitters must not be 
operated at locations more than 48 kilometers (30 miles) from all 
associated base stations.
    (c) Protection from intermodulation interference. Base transmitter 
locations must be at least 1.6 kilometers (1 mile) from the current main 
transmitter locations of all TV stations transmitting on TV channels 
separated by 2, 3, 4, 5, 7, or 8 TV channels from the TV channel 
containing the frequencies on which the base station will transmit. This 
requirement is intended to reduce the likelihood of intermodulation 
interference.
    (d) Adjacent channel protection from mobile transmitters. Base 
transmitter locations must be at least 145 kilometers (90 miles) from 
the applicable protected TV station locations specified in this 
paragraph. This requirement is intended to provide a 0 dB minimum 
desired to undesired signal strength ratio at the Grade B contour of an 
adjacent channel TV station. Note: All coordinates are referenced to 
North American Datum 1983 (NAD83).

this section from the applicable protected TV station locations 
specified in paragraph (e)(1) of this section. This requirement is 
intended to provide a 40 dB minimum desired to undesired signal strength 
ratio at the Grade B contour of a co-channel TV station.

    (f) Co-channel protection from base transmitters with high antennas. 
This paragraph applies only to base transmitter locations in the New 
York-Northeastern New Jersey urban area that utilize an antenna height 
of more than 152 meters (500 feet) above average terrain. The distance 
between the location of such a base transmitter and the applicable 
protected TV station location specified in this paragraph must equal or 
exceed the sum of the distance from the base transmitter location to the 
radio horizon in the direction of the specified location and 89 
kilometers (55 miles--representing the distance from the main 
transmitter location of the TV station to its Grade B contour in the 
direction of the base transmitter). The distance to the radio horizon is 
calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR14DE98.026

Where d is the distance to the radio horizon in kilometers h is the 
          height of the antenna center of radiation above ground level 
          in meters

    (g) The FCC may waive specific distance separation requirements of 
paragraphs (d) through (f) of this section if the applicant submits an 
engineering analysis which demonstrates that terrain effects and/or 
operation with less effective radiated power would satisfy the 
applicable minimum desired to undesired signal strength ratios at the 
Grade B contours of the protected TV stations. For this purpose, the 
Grade B contour of a TV station is deemed to be a circle with a 89 
kilometer (55 mile) radius, centered on the protected TV station 
location, and along which the median TV signal field strength is 64 
dB[micro]V/m. In any showing intended to demonstrate compliance with the 
minimum desired to undesired signal ratio requirements of this section, 
all predicted field strengths must have been determined using the UHF TV 
propagation curves contained in part 73 of this chapter.

Sec.  22.659  Effective radiated power limits.

    The purpose of the rules in this section, which limit effective 
radiated power (ERP), is to reduce the likelihood that interference to 
television reception from public mobile operations on these channels 
will occur. The protected TV station locations specified in this section 
are the locations of record as of September 1974, and these do not 
change even though the TV stations may have been subsequently relocated.
    (a) Maximum ERP. The ERP of base transmitters must not exceed 100 
Watts under any circumstances. The ERP of mobile transmitters must not 
exceed 60 Watts under any circumstances.
    (b) Co-channel protection from base transmitters. The ERP of base 
transmitters in the New York-Northeastern New Jersey urban area must not 
exceed the limits in the tables referenced in paragraphs (b)(2) and 
(b)(3) of this section. The limits depend upon the height above average 
terrain of the base transmitter antenna and the distance between the 
base transmitter and the nearest protected TV station location in 
paragraph (b)(1) of this section.

                 Subpart F_Rural Radiotelephone Service



Sec.  22.701  Scope.

    The rules in this subpart govern the licensing and operation of 
stations and systems in the Rural Radiotelephone Service. The licensing 
and operation of these stations and systems is also subject to rules 
elsewhere in this part that apply generally to the Public Mobile 
Services. In case of conflict, however, the rules in this subpart 
govern.



Sec.  22.702  Eligibility.

    Existing and proposed communications common carriers are eligible to 
hold authorizations to operate conventional central office, interoffice 
and rural stations in the Rural Radiotelephone Service. Subscribers are 
also eligible to hold authorizations to operate rural subscriber 
stations in the Rural Radiotelephone Service.

[69 FR 75170, Dec. 15, 2004]



Sec.  22.703  Separate rural subscriber station authorization not required.

    A separate authorization is not required for rural subscriber 
stations for which the effective radiated power does not exceed 60 Watts 
and for which FAA notification of construction or alteration of the 
antenna structure is not required (see criteria in Sec.  17.7 of this 
chapter). Authority to operate such rural subscriber stations is 
conferred by the authorization of the central office or base station 
from which they receive service.



Sec.  22.705  Rural radiotelephone system configuration.

    Stations in the Rural Radiotelephone Service are authorized to 
communicate as follows:
    (a) Rural subscriber stations are authorized to communicate with and 
through the central office station(s) with which they are associated. 
However, where the establishment of a central office station in this 
service is not feasible, rural subscriber stations may be authorized to 
communicate with and through a base station in the Paging and 
Radiotelephone Service.
    (b) Central office stations may communicate only with rural 
subscriber stations.

[[Page 81]]

    (c) Interoffice stations may communicate only with other interoffice 
stations.



Sec.  22.709  Rural radiotelephone service application requirements.

    In addition to information required by Subparts B and D of this 
part, FCC Form 601 applications for authorization to operate a station 
in the Rural Radiotelephone Service must contain the applicable 
supplementary information described in this section.
    (a) Interoffice stations. Applications for authority to operate a 
new interoffice station or to add transmitters or points of 
communications to an existing interoffice station must contain an 
exhibit demonstrating that the requested facilities would be used only 
for interconnecting central office stations and explaining why the use 
of alternative existing radio or wire facilities is not feasible.
    (b) Technical information required. For each transmitter in the 
Rural Radiotelephone Service, the following information is required by 
FCC Form 601:
    (1) Location description: city; county; state; geographic 
coordinates correct to 1 second, the datum used 
(NAD83), site elevation above mean sea level, proximity to adjacent 
market boundaries and international borders;
    (2) Antenna height to tip above ground level, the height of the 
center of radiation of the antenna above the average terrain, the height 
of the antenna center of radiation above the average elevation of the 
terrain along each of the 8 cardinal radials, antenna gain in the 
maximum lobe, the beamwidth of the maximum lobe of the antenna, a polar 
plot of the horizontal gain pattern of the antenna, the electric field 
polarization of the wave emitted by the antenna when installed as 
proposed;
    (3) The center frequency of each channel requested, the maximum 
effective radiated power, the effective radiated power in each of the 
cardinal radial directions, any non-standard emission types to be used, 
including bandwidth and modulation type, the transmitter classification 
(e.g. central office), and the locations and call signs, if any, of any 
fixed points of communication.
    (c) No landline facilities. Each application for a central office 
station must contain an exhibit showing that it is impracticable to 
provide the required communication service by means of landline 
facilities.
    (d) Interference exhibit. Applications for central office, 
interoffice and relay stations must include an exhibit identifying co-
channel facilities and demonstrating, in accordance with Sec.  22.715 
that the proposed station, if authorized, would not cause interference 
to the service of those co-channel facilities. This exhibit must:
    (1) For UHF channels, identify each protected transmitter located 
within 108 kilometers (67 miles) of the proposed transmitter in 
directions in which the distance to the interfering contour is 76.4 
kilometers (47.5 miles) or less, and within 178 kilometers (111 miles) 
of the proposed transmitter in directions in which the distance to the 
interfering contour exceeds 76.4 kilometers (47.5 miles); and identify 
each protected Basic Exchange Telephone Radio System central office 
transmitter in the rural Radiotelephone Service within 231 kilometers 
(144 miles).
    (2) For VHF channels, identify each protected transmitter located 
within 135 kilometers (84 miles) of the proposed transmitter in 
directions in which the distance to the interfering contour is 93.3 
kilometers (58 miles) or less, and within 178 kilometers (111 miles) of 
the proposed transmitter in directions in which the distance to the 
interfering contour exceeds 93.3 kilometers (58 miles).
    (3) For each protected transmitter identified, show the results of 
distance calculations indicating that there would be no overlap of 
service and interfering contours, or alternatively, indicate that the 
licensee of or applicant for the protected transmitter and/or the 
applicant, as required, have agreed in writing to accept any 
interference resulting from operation of the proposed transmitter.
    (e) Blocking probability. Applications for authority to operate 
basic exchange telephone radio systems (BETRS) that request more than 
two channel pairs must include an exhibit containing calculations 
showing that the number of

[[Page 82]]

channels requested is the minimum necessary to achieve the required 
grade of service (in terms of blocking probability), and that there will 
be adequate spectrum available in the area to meet realistic estimates 
of current and future demand for paging, two-way mobile and rural 
radiotelephone services (see Sec.  22.719(c)). Applications for 
authority to operate new conventional rural radiotelephone systems that 
request more than two channel pairs must include a statement explaining 
why BETRS technology is not being proposed.
    (f) Antenna Information. Upon request by an applicant, licensee, or 
the Commission, a part 22 applicant or licensee of whom the request is 
made shall furnish the antenna type, model, and the name of the antenna 
manufacturer to the requesting party within ten (10) days of receiving 
written notification.

[59 FR 59507, Nov. 17, 1994, as amended at 59 FR 59954, Nov. 21, 1994; 
63 FR 68948, Dec. 14, 1998; 64 FR 53240, Oct. 1, 1999]



Sec.  22.711  Provision of information to applicants.

    Licensees in the Rural Radio Service must, upon request by a bona-
fide prospective applicant, provide to such applicant the information 
required by Sec.  22.709 regarding the portion of the licensee's 
operations that potentially could affect, or be affected by, the 
prospective applicant's proposed station, if such information is not 
already on file with the FCC. This information must be provided to the 
bona-fide prospective applicant no later than 30 days after receipt of 
the information request.

[59 FR 59954, Nov. 21, 1994]



Sec.  22.713  Construction period for rural radiotelephone stations.

    The construction period for stations in the Rural Radiotelephone 
Service is 12 months.



Sec.  22.715  Technical channel assignment criteria for rural 
radiotelephone stations.

    Channels are assigned in the Rural Radiotelephone Service using the 
procedures in Sec.  22.567.



Sec.  22.717  Procedure for mutually exclusive applications in the 
Rural Radiotelephone Service.

    Mutually exclusive applications in the Rural Radiotelephone Service, 
including those that are mutually exclusive with applications in the 
Paging and Radiotelephone Service, are processed in accordance with 
Sec.  22.131 and with this section.
    (a) Applications in the Rural Radiotelephone Service may be mutually 
exclusive with applications in the Paging and Radiotelephone Service if 
they seek authorization to operate facilities on the same channel in the 
same area, or the technical proposals are otherwise in conflict. See 
Sec.  22.567.
    (b) A modification application in either service filed on the 
earliest filing date may cause all later-filed mutually exclusive 
applications of any type in either service to be ``cut off'' (excluded 
from a same-day filing group) and dismissed, pursuant to Sec.  
22.131(c)(3)(ii) and Sec.  22.131(c)(4).

[59 FR 59956, Nov. 21, 1994, as amended at 62 FR 11636, Mar. 12, 1997]



Sec.  22.719  Additional channel policy for rural radiotelephone stations.

    The rules in this section govern the processing of applications for 
central office stations that request a rural radiotelephone channel pair 
when the applicant has applied for or been granted an authorization for 
other rural radiotelephone channel pairs in the same area. The general 
policy of the FCC is to promote effective use of the spectrum by 
encouraging the use of spectrum-efficient technologies (i.e. BETRS) and 
by assigning the minimum number of channels necessary to provide 
service.
    (a) Transmitters in same area. Any central office station 
transmitter on any channel pair listed in Sec.  22.725 is considered to 
be in the same area as another central office station transmitter on any 
other channel pair listed in Sec.  22.725 if the transmitting antennas 
are located within 10 kilometers (6.2 miles) of each other.
    (b) Initial channel pairs. The FCC does not assign more than two 
channel pairs for new central office stations, unless there are more 
than eight rural subscriber stations to be served. Stations

[[Page 83]]

are considered to be new if there are no authorized transmitters on any 
channel listed in Sec.  22.725 controlled by the applicant in the same 
geographic area.
    (c) Additional channel pairs. Applications for central office 
station transmitters to be located in the same area as an authorized 
central office station controlled by the applicant, but to operate on a 
different channel pair(s) are considered as requests for additional 
channel pair(s) for the authorized central office station. The FCC may 
grant applications for additional channel pairs provided that the need 
for each additional channel pair (after the first two) is established 
and fully justified in terms of achieving the required grade of service 
(blocking probability), and the applicant demonstrates that there will 
still be adequate spectrum available in the area to meet realistic 
estimates of current and future demand for paging, two-way mobile and 
rural radiotelephone services. In the case of conventional rural 
radiotelephone central office stations, an explanation must be provided 
as to why BETRS technology is not being used instead of additional 
channel pairs.

               Conventional Rural Radiotelephone Stations



Sec.  22.721  Geographic area authorizations.

    Eligible persons may apply for a paging geographic area 
authorization in the Rural Radiotelephone Service, on the channel pairs 
listed in Sec.  22.725, by following the procedures and requirements set 
forth in Sec.  22.503 for paging geographic area authorizations.

[62 FR 11636, Mar. 12, 1997]



Sec.  22.723  Secondary site-by-site authorizations.

    Authorizations for new facilities (including new sites and 
additional channel pairs for existing sites) in the Rural Radiotelephone 
Service (including BETRS facilities) may be granted after May 12, 1997 
only on the condition that such authorizations shall be secondary to any 
existing or future co-channel paging geographic area authorization in 
the Paging and Radiotelephone Service or the Rural Radiotelephone 
Service. If the paging geographic area licensee notifies the Rural 
Radiotelephone Service licensee that operation of a co-channel secondary 
facility must be discontinued because it may cause interference to 
existing or planned facilities, the Rural Radiotelephone Service 
licensee must discontinue operation of that facility on the particular 
channel pair involved no later than six months after such notice.

[62 FR 11636, Mar. 12, 1997]



Sec.  22.725  Channels for conventional rural radiotelephone stations and 
basic exchange telephone radio systems.

    The following channels are allocated for paired assignment to 
transmitters that provide conventional rural radiotelephone service and 
to transmitters in basic exchange telephone radio systems. These 
channels may be assigned for use by central office or rural subscriber 
stations as indicated, and interoffice stations. These channels may be 
assigned also for use by relay stations in systems where it would be 
impractical to provide rural radiotelephone service without the use of 
relay stations. All channels have a bandwidth of 20 kHz and are 
designated by their center frequencies in MegaHertz.

Sec.  22.727  Power limits for conventional rural radiotelephone
transmitters.

    The transmitting power of transmitters operating on the channels 
listed in Sec.  22.725 must not exceed the limits in this section.
    (a) Maximum ERP. The effective radiated power (ERP) of central 
office and rural subscriber station transmitters must not exceed the 
applicable limits in this paragraph under any circumstances.

------------------------------------------------------------------------

------------------------------------------------------------------------

    (b) Basic power limit. Except as provided in paragraph (d) of this 
section, the ERP of central office station transmitters must not exceed 
500 Watts.
    (c) Height-power limits. Except as provided in paragraph (d) of this 
section, the ERP of central office station transmitters must not exceed 
the amount that would result in an average distance to the ``service 
contour'' of 41.6 kilometers (26 miles) for VHF channels or 30.7 
kilometers (19 miles) for UHF channels. The average distance to the 
``service contour'' is calculated by taking the arithmetic mean of the 
distances determined using the procedures specified in Sec.  22.567 for 
the eight cardinal radial directions, excluding cardinal radial 
directions for which 90% or more of the distance so calculated is over 
water.
    (d) Encompassed interfering contour areas. Central office station 
transmitters are exempt from the basic power and height-power limits of 
this section if the area within their interfering contours is totally 
encompassed by the interfering contours of operating co-channel central 
office station transmitters controlled by the same licensee. For the 
purpose of this paragraph, operating transmitters are authorized 
transmitters that are providing service to subscribers.
    (e) Adjacent channel protection. The ERP of central office station 
transmitters must not exceed 500 Watts if they transmit on channel 
454.025 MHz and are located less than 7 kilometers (4.3 miles) from any 
Private Radio Services station receiving on adjacent channel 454.000 
MHz.

[59 FR 59507, Nov. 17, 1994, as amended at 70 FR 19309, Apr. 13, 2005]



Sec.  22.731  Emission limitations.

    Upon application for multichannel operation, the FCC may authorize 
emission bandwidths wider than those specified in Sec.  22.357, provided 
that spectrum utilization is equal to or better than that achieved by 
single channel operation.



Sec.  22.733  Priority of service.

    Within the Rural Radiotelephone Service, the channels listed in 
Sec.  22.725 are intended primarily for use in rendition of public 
message service between rural subscriber and central office stations and 
to provide radio trunking facilities between central offices. The 
channels may also be used, however, for the rendition of private leased-
line communication service provided that such usage would not reduce or 
impair the extent or quality of communication service that would be 
available, in the absence of private leased-line service, to the general 
public receiving or subsequently requesting public message service from 
a central office.



Sec.  22.737  Temporary fixed stations.

    The FCC may, upon proper application therefor, authorize the 
construction and operation of temporary fixed

[[Page 85]]

stations. Temporary fixed stations are to be used as rural subscriber, 
interoffice, or central office stations when those stations are 
unavailable or when service from those stations is disrupted by storms 
or emergencies.
    (a) Six month limitation. If it is necessary for a temporary fixed 
station to remain at the same location for more than six months, the 
licensee of that station must apply for authorization to operate the 
station at the specific location at least 30 days before the end of the 
six month period.
    (b) International communications. Communications between the United 
States and Canada or Mexico must not be carried using a temporary fixed 
station without prior authorization from the FCC. Licensees desiring to 
carry such communications should apply sufficiently in advance to allow 
for the time necessary to coordinate with Canada or Mexico.

Sec.  22.807  General aviation air-ground application requirements.

    In addition to the information required by subparts B and D of this 
part, FCC Form 601 applications for authorization to operate a general 
aviation air-ground station must contain the applicable supplementary 
information described in this section.
    (a) Administrative information. The following information is 
required by FCC Form 601.
    (1) The number of transmitter sites for which authorization is 
requested.
    (2) The call sign(s) of other facilities in the same area that are 
ultimately controlled by the real party in interest to the application.
    (b) Technical information required. For each transmitter in the 
Rural Radiotelephone Service, the following information is required by 
FCC Form 601:
    (1) Location description, city, county, state, geographic 
coordinates (NAD83) correct to 1 second, site 
elevation above mean sea level, proximity to adjacent market boundaries 
and international borders;
    (2) Antenna height to tip above ground level, antenna gain in the 
maximum lobe, the electric field polarization of the wave emitted by the 
antenna when installed as proposed;
    (3) The center frequency of each channel requested, the maximum 
effective radiated power, any non-standard emission types to be used, 
including bandwidth and modulation type and the transmitter 
classification (e.g. ground or signaling).

amended at 70 FR 19309, Apr. 13, 2005]



Sec.  22.809  Transmitting power limits.

    The transmitting power of ground and airborne mobile transmitters 
operating on the channels listed in Sec.  22.805 must not exceed the 
limits in this section.
    (a) Ground station transmitters. The effective radiated power of 
ground stations must not exceed 100 Watts and must not be less than 50 
Watts, except as provided in Sec.  22.811.
    (b) Airborne mobile transmitters. The transmitter power output of 
airborne mobile transmitters must not exceed 25 Watts and must not be 
less than 4 Watts.



Sec.  22.813  Technical channel pair assignment criteria.

    The rules in this section establish technical assignment criteria 
for the channel pairs listed in Sec.  22.805. These criteria are 
intended to provide substantial service volumes over areas that have 
significant local and regional general aviation activity, while 
maintaining the continuous nationwide in-route coverage of the original 
geographical layout.
    (a) Distance separation for co-channel ground stations. The FCC may 
grant an application requesting assignment of a communication channel 
pair to a proposed ground transmitter only if the proposed antenna 
location is at least 800 kilometers (497 miles) from the antenna 
location of the nearest co-channel ground transmitter in the United 
States, its territories and possessions; and 1000 kilometers (621 miles) 
from the antenna location of the nearest co-channel ground transmitter 
in Canada.
    (b) Dispersion. The FCC may grant an application requesting 
assignment of a communication channel pair to a proposed ground 
transmitter only if there are no more than five different communication 
channel pairs already assigned to ground transmitters with antenna 
locations within a 320 kilometer (199 mile) radius of the proposed 
antenna location.



Sec.  22.815  Construction period for general aviation ground stations.

    The construction period (see Sec.  1.946 of this chapter) for 
general aviation ground stations is 12 months.

[70 FR 19310, Apr. 13, 2005]



Sec.  22.817  Additional channel policies.

    The rules in this section govern the processing of applications for 
authority to operate a ground station transmitter on any ground station 
communication channel listed in Sec.  22.805 when the applicant has 
applied or been

[[Page 87]]

granted an authorization for other ground station communication channels 
in the same area. The general policy of the FCC is to assign one ground 
station communication channel in an area to a carrier per application 
cycle, up to a maximum of six ground station communication channels per 
area. That is, a carrier must apply for one ground station communication 
channel, receive the authorization, construct the station, and notify 
the FCC of commencement of service before applying for an additional 
ground station communication channel in that area.
    (a) Air-ground transmitters in same area. Any transmitter on any of 
the ground station channels listed in Sec.  22.805 is considered to be 
in the same area as another transmitter on any ground station channel 
listed in Sec.  22.805 if it is located less than 350 kilometers (217 
miles) from that transmitter.
    (b) Initial channel. The FCC will not assign more than one ground 
station communication channel for new ground stations. Ground stations 
are considered to be new if there are no authorized ground station 
transmitters on any channel listed in Sec.  22.805 controlled by the 
applicant in the same area.
    (c) Additional channel. Applications for ground transmitters to be 
located in the same area as an authorized ground station controlled by 
the applicant, but to operate on a different ground station 
communication channel, are considered as requesting an additional 
channel for the authorized station.
    (d) Amendment of pending application. If the FCC receives and 
accepts for filing an application for a ground station transmitter to be 
located in the same area as a ground station transmitter proposed in a 
pending application previously filed by the applicant, but on a 
different ground station communication channel, the subsequent 
application is treated as a major amendment to change the technical 
proposal of the prior application. The filing date of any application so 
amended is the date the FCC received the subsequent application.
    (e) Dismissal of premature applications for additional channel. If 
the FCC receives an application requesting an additional ground station 
communication channel for an authorized ground station prior to 
receiving notification that the station is providing service to 
subscribers on the authorized channel(s), the FCC may dismiss that 
application without prejudice.
    (f) Dismissal of applications for seventh channel. If the FCC 
receives an application requesting an additional ground station 
communication channel for an authorized ground station which would, if 
granted, result in that station being assigned more than six ground 
station communication channels in the same area, the FCC may dismiss 
that application without prejudice.

    No individual or entity may hold, directly or indirectly, a 
controlling interest in licenses authorizing the use of more than three 
megahertz of spectrum (either shared or exclusive) in the 800 MHz 
commercial aviation Air-Ground Radiotelephone Service frequency bands 
(see Sec.  22.857). Individuals and entities with either de jure or de 
facto control of a licensee in these bands will be considered to have a 
controlling interest in its license(s). For purposes of this rule, the 
definitions of ``controlling interests'' and ``affiliate'' set forth in 
paragraphs (c)(2) and (c)(5) of Sec.  1.2110 of this chapter shall 
apply.

operating in these frequency bands are referred to in this part as 
``commercial aviation'' systems.

[70 FR 19310, Apr. 13, 2005]

[[Page 88]]



Sec.  22.859  Incumbent commercial aviation air-ground systems.

    This section contains rules concerning continued operation of 
commercial aviation air-ground systems that were originally authorized 
prior to January 1, 2004 to provide radiotelephone service using 
narrowband (6 kHz) channels, and that have been providing service 
continuously since the original commencement of service (hereinafter 
``incumbent systems'').
    (a) An incumbent system may continue to operate under its 
authorization, for the remaining term of such authorization, subject to 
the terms and conditions attached thereto. Wherever such technical and 
operational conditions differ from technical and operational rules in 
this subpart, those conditions shall govern its operations.
    (b) Notwithstanding any other provision in this chapter, the 
licensee of an incumbent system shall not be entitled to an expectation 
of renewal of said authorization.
    (c) During the period that an incumbent system continues to operate 
and provide service pursuant to paragraph (a) of this section, air-
ground systems of licensees holding a new authorization for the spectrum 
within which the incumbent system operates must not cause interference 
to the incumbent system. Protection from interference requires that the 
signals of the new systems must not exceed a ground station received 
power of -130 dBm within a 6 kHz receive bandwidth, calculated assuming 
a 0 dBi vertically polarized receive antenna.

[70 FR 19310, Apr. 13, 2005]



Sec.  22.861  Emission limitations.

    The rules in this section govern the spectral characteristics of 
emissions for commercial aviation systems in the Air-Ground 
Radiotelephone Service. Commercial aviation air-ground systems may use 
any type of emission or technology that complies with the technical 
rules in this subpart.
    (a) Out of band emissions. The power of any emission outside of the 
authorized operating frequency ranges must be attenuated below the 
transmitting power (P) by a factor of at least 43 + 10 log (P) dB.
    (b) Measurement procedure. Compliance with these rules is based on 
the use of measurement instrumentation employing a resolution bandwidth 
of 100 kHz or greater. In the 1 MHz bands immediately outside and 
adjacent to the frequency block a resolution bandwidth of at least one 
percent of the emission bandwidth of the fundamental emission of the 
transmitter may be employed. A narrower resolution bandwidth is 
permitted in all cases to improve measurement accuracy provided the 
measured power is integrated over the full required measurement 
bandwidth (i.e., 100 kHz or 1 percent of emission bandwidth, as 
specified). The emission bandwidth is defined as the width of the signal 
between two points, one below the carrier center frequency and one above 
the carrier center frequency, outside of which all emissions are 
attenuated at least 26 dB below the transmitter power.
    (c) Alternative out of band emission limit. The licensee(s) of 
commercial aviation air-ground systems, together with affected licensees 
of Cellular Radiotelephone Service systems operating in the spectrum 
immediately below and adjacent to the commercial aviation air-ground 
bands, may establish an alternative out of band emission limit to be 
used at the 849 MHz and 894 MHz band edge(s) in specified geographical 
areas, in lieu of that set forth in this section, pursuant to a private 
contractual arrangement of all affected licensees and applicants. In 
this event, each party to such contract shall maintain a copy of the 
contract in their station files and disclose it to prospective assignees 
or transferees and, upon request, to the FCC.
    (d) Interference caused by out of band emissions. If any emission 
from a transmitter operating in this service results in interference to 
users of another radio service, the FCC may require a greater 
attenuation of that emission than specified in this section.

[70 FR 19310, Apr. 13, 2005]



Sec.  22.863  Frequency stability.

    The frequency stability of equipment used under this subpart shall 
be sufficient to ensure that, after accounting for Doppler frequency 
shifts, the occupied bandwidth of the fundamental

[[Page 89]]

emissions remains within the authorized frequency bands of operation.

[70 FR 19310, Apr. 13, 2005]



Sec.  22.867  Effective radiated power limits.

    The effective radiated power (ERP) of ground and airborne stations 
operating on the frequency ranges listed in Sec.  22.857 must not exceed 
the limits in this section.
    (a) The peak ERP of airborne mobile station transmitters must not 
exceed 12 Watts.
    (b) The peak ERP of ground station transmitters must not exceed 500 
Watts.

[70 FR 19310, Apr. 13, 2005]



Sec.  22.873  Construction requirements for commercial aviation air-ground
systems.

    Licensees authorized to use more than one megahertz (1 MHz) of the 
800 MHz commercial aviation air-ground spectrum allocation (see Sec.  
22.857) must make a showing of ``substantial service'' as set forth in 
this section. Failure by any such licensee to meet this requirement will 
result in forfeiture of the license and the licensee will be ineligible 
to regain it. Licensees authorized to use one megahertz or less of the 
800 MHz commercial aviation air-ground spectrum allocation are not 
subject to the requirements in this section.
    (a) ``Substantial service'' is defined as service that is sound, 
favorable, and substantially above a level of mediocre service that just 
might minimally warrant renewal.
    (b) Each commercial aviation air-ground system subject to the 
requirements of this section must demonstrate substantial service within 
5 years after grant of the authorization. Substantial service may be 
demonstrated by, but is not limited to, either of the following ``safe 
harbor'' provisions:
    (1) Construction and operation of 20 ground stations, with at least 
one ground station located in each of the 10 Federal Aviation 
Administration regions; or,
    (2) Provision of service to the airspace of 25 of the 50 busiest 
airports (as measured by annual passenger boardings).

Sec.  22.877  Unacceptable interference to part 90 non-cellular 800 MHz
licensees from commercial aviation air-ground systems.

    The definition of unacceptable interference to non-cellular part 90 
licensees in the 800 MHz band from commercial aviation air-ground 
systems is the same as the definition set forth in Sec.  22.970 which is 
applicable to Cellular Radiotelephone Service systems.

[70 FR 19311, Apr. 13, 2005]



Sec.  22.878  Obligation to abate unacceptable interference.

    This section applies only to commercial aviation ground stations 
transmitting in the 849-851 MHz band, other than commercial aviation 
ground stations operating under the authority of a license originally 
granted prior to January 1, 2004.
    (a) Strict responsibility. Any licensee who, knowingly or 
unknowingly, directly or indirectly, causes or contributes to causing 
unacceptable interference to a non-cellular part 90 licensee in the 800 
MHz band, as defined in Sec.  22.877, shall be strictly accountable to 
abate the interference, with full cooperation and utmost diligence, in 
the shortest time practicable. Interfering licensees shall consider all 
feasible interference abatement measures, including, but not limited to, 
the remedies specified in the interference resolution procedures set 
forth in Sec.  22.879. This strict responsibility obligation applies to 
all forms of interference, including out-of-band emissions and 
intermodulation.
    (b) Joint and Several responsibility. If two or more licensees, 
whether in the commercial aviation air-ground radiotelephone service or 
in the Cellular Radiotelephone Service (see Sec.  22.971), knowingly or 
unknowingly, directly or indirectly, cause or contribute to causing 
unacceptable interference to a non-cellular part 90 licensee in the 800 
MHz band, as defined in Sec.  22.877, such licensees shall be jointly 
and severally responsible for abating interference, with full 
cooperation and utmost diligence, in the shortest practicable time.

[[Page 90]]

    (1) This joint and several responsibility rule requires interfering 
licensees to consider all feasible interference abatement measures, 
including, but not limited to, the remedies specified in the 
interference resolution procedures set forth in Sec.  22.879(c). This 
joint and several responsibility rule applies to all forms of 
interference, including out-of-band emissions and intermodulation.
    (2) Any licensee that can show that its signal does not directly or 
indirectly cause or contribute to causing unacceptable interference to a 
non-cellular part 90 licensee in the 800 MHz band, as defined in Sec.  
22.877, shall not be held responsible for resolving unacceptable 
interference. Notwithstanding, any licensee that receives an 
interference complaint from a public safety/CII licensee shall respond 
to such complaint consistent with the interference resolution procedures 
set forth in Sec.  22.879.

[70 FR 19411, Apr. 13, 2005]



Sec.  22.879  Interference resolution procedures.

    This section applies only to commercial aviation ground stations 
transmitting in the 849-851 MHz band, other than commercial aviation 
ground stations operating under the authority of a license originally 
granted prior to January 1, 2004.
    (a) Initial notification. Commercial aviation air-ground system 
licensees may receive initial notification of interference from non-
cellular part 90 licensees in the 800 MHz band pursuant to Sec.  
90.674(a) of this chapter.
    (1) Commercial aviation air-ground system licensees shall join with 
part 90 ESMR licensees and Cellular Radiotelephone Service licensees in 
utilizing an electronic means of receiving the initial notification 
described in Sec.  90.674(a) of this chapter. See Sec.  22.972.
    (2) Commercial aviation air-ground system licensees must respond to 
the initial notification described in Sec.  90.674(a) of this chapter as 
soon as possible and no later than 24 hours after receipt of 
notification from a part 90 public safety/CII licensee. This response 
time may be extended to 48 hours after receipt from other part 90 non-
cellular licensees provided affected communications on these systems are 
not safety related.
    (b) Interference analysis. Commercial aviation air-ground system 
licensees--who receive an initial notification described in Sec.  
90.674(a) of this chapter--shall perform a timely analysis of the 
interference to identify the possible source. Immediate on-site visits 
may be conducted when necessary to complete timely analysis. 
Interference analysis must be completed and corrective action initiated 
within 48 hours of the initial complaint from a part 90 public safety/
CII licensee. This response time may be extended to 96 hours after the 
initial complaint from other part 90 non-cellular licensees provided 
affected communications on these systems are not safety related. 
Corrective action may be delayed if the affected licensee agrees in 
writing (which may be, but is not required to be, recorded via e-mail or 
other electronic means) to a longer period.
    (c) Mitigation steps. Any commercial aviation air-ground system that 
is responsible for causing unacceptable interference to non-cellular 
part 90 licensees in the 800 MHz band shall take affirmative measures to 
resolve such interference.
    (1) Commercial aviation air-ground system licensees found to 
contribute to unacceptable interference, as defined in Sec.  22.877, 
shall resolve such interference in the shortest time practicable. 
Commercial aviation air-ground system licensees must provide all 
necessary test apparatus and technical personnel skilled in the 
operation of such equipment as may be necessary to determine the most 
appropriate means of timely eliminating the interference. However, the 
means whereby interference is abated or the technical parameters that 
may need to be adjusted is left to the discretion of the commercial 
aviation air-ground system licensee, whose affirmative measures may 
include, but not be limited to, the following techniques:
    (i) Increasing the desired power of the public safety/CII signal;
    (ii) Decreasing the power of the commercial aviation air-ground 
system signal;
    (iii) Modifying the commercial aviation air-ground system antenna 
height;

[[Page 91]]

    (iv) Modifying the commercial aviation air-ground system antenna 
characteristics;
    (v) Incorporating filters into the commercial aviation air-ground 
system transmission equipment;
    (vi) Changing commercial aviation air-ground system frequencies; and
    (vii) Supplying interference-resistant receivers to the affected 
public safety/CII licensee(s). If this technique is used, in all 
circumstances, commercial aviation air-ground system licensees shall be 
responsible for all costs thereof.
    (2) Whenever short-term interference abatement measures prove 
inadequate, the affected part 90 non-cellular licensee shall, consistent 
with but not compromising safety, make all necessary concessions to 
accepting interference until a longer-term remedy can be implemented.
    (3) When a part 90 public safety licensee determines that a 
continuing presence of interference constitutes a clear and imminent 
danger to life or property, the licensee causing the interference must 
discontinue the associated operation immediately, until a remedy can be 
identified and applied. The determination that a continuing presence 
exists that constitutes a clear and imminent danger to life or property, 
must be made by written statement that:
    (i) Is in the form of a declaration, notarized affidavit, or 
statement under penalty or perjury, from an officer or executive of the 
affected public safety licensee;
    (ii) Thoroughly describes the basis of the claim of clear and 
imminent danger;
    (iii) Was formulated on the basis of either personal knowledge or 
belief after due diligence;
    (iv) Is not proffered by a contractor or other third party; and,
    (v) Has been approved by the Chief of the Public Safety and Homeland 
Security Bureau or other designated Commission official. Prior to the 
authorized official making a determination that a clear and imminent 
danger exists, the associated written statement must be served by hand-
delivery or receipted fax on the applicable offending licensee, with a 
copy transmitted by the fastest available means to the Washington, DC 
office of the Commission's Public Safety and Homeland Security Bureau.

[70 FR 19311, Apr. 13, 2005, as amended at 71 FR 69038, Nov. 29, 2006]



Sec.  22.880  Information exchange.

    (a) Prior notification. Public safety/CII licensees may notify a 
commercial aviation air-ground system licensee that they wish to receive 
prior notification of the activation or modification of a commercial 
aviation air-ground system ground station site in their area. 
Thereafter, the commercial aviation air-ground system licensee must 
provide the following information to the public safety/CII licensee at 
least 10 business days before a new ground station is activated or an 
existing ground station is modified:
    (1) Location;
    (2) Effective radiated power;
    (3) Antenna manufacturer, model number, height above ground level 
and up tilt angle, as installed;
    (4) Channels available for use.
    (b) Purpose of prior notification. The prior notification of ground 
station activation or modification is for informational purposes only: 
public safety/CII licensees are not afforded the right to accept or 
reject the activation of a proposed ground station or to unilaterally 
require changes in its operating parameters. The principal purposes of 
prior notification are to:
    (1) Allow a public safety licensee to advise the commercial aviation 
air-ground system licensee whether it believes a proposed ground station 
will generate unacceptable interference;
    (2) Permit commercial aviation air-ground system licensee(s) to make

                Subpart H_Cellular Radiotelephone Service



Sec.  22.900  Scope.

    The rules in this subpart govern the licensing and operation of 
cellular radiotelephone systems. Licensing and operation of these 
systems are also subject to rules elsewhere in this part that apply 
generally to the Public Mobile Services. In case of conflict, however, 
the rules in this subpart govern.



Sec.  22.901  Cellular service requirements and limitations.

    The licensee of each Cellular system is responsible for ensuring 
that its Cellular system operates in compliance with this section. Each 
Cellular system must provide either mobile service, fixed service, or a 
combination of mobile and fixed service, subject to the requirements, 
limitations and exceptions in this section. Mobile service provided may 
be of any type, including two-way radiotelephone, dispatch, one-way or 
two-way paging, and personal communications services (as defined in part 
24 of this chapter). Fixed service is considered to be primary service, 
as is mobile service. When both mobile and fixed services are provided, 
they are considered to be co-primary services. In providing Cellular 
service, each Cellular system may incorporate any technology that meets 
all applicable technical requirements in this part.

Sec.  22.907  Coordination of channel usage.

    Licensees in the Cellular Radiotelephone Service must coordinate, 
with the appropriate parties, channel usage at each transmitter location 
within 121 kilometers (75 miles) of any transmitter locations authorized 
to other licensees or proposed by other applicants, except those with 
mutually exclusive applications. Licensees utilizing systems employing a 
frequency re-use factor of 1 (universal re-use) are exempt from this 
requirement.

[[Page 93]]

    (a) Licensees must cooperate and make reasonable efforts to resolve 
technical problems that may inhibit effective and efficient use of the 
cellular radio spectrum; however, licensees are not obligated to suggest 
extensive changes to or redesign other licensees' cellular systems. 
Licensees must make reasonable efforts to avoid blocking the growth of 
other cellular systems that are likely to need additional capacity in 
the future.
    (b) If technical problems are addressed by an agreement or operating 
agreement between the licensees that would result in a reduction of 
quality or capacity of either system, the licensees must notify the 
Commission by updating FCC Form 601.

Sec.  22.911  Cellular geographic service area.

    The Cellular Geographic Service Area (CGSA) of a Cellular system is 
the geographic area considered by the FCC to be served by the Cellular 
system and is the area within which cellular systems are entitled to 
protection and adverse effects for the purpose of determining whether a 
petitioner has standing are recognized. The CGSA is the composite of the 
service areas of all of the cells in the system, excluding any Unserved 
Area (even if it is served on a secondary basis) or area within the CGSA 
of another Cellular system. The service area of a cell is the area 
within its service area boundary (SAB). Licensees that use power 
spectral density (PSD) at cell sites within their licensed geographic 
area are subject to paragraph (c) of this section; all other licensees 
are subject to paragraph (a) (or, as applicable, paragraph (b)) of this 
section. If the calculation under paragraph (a), (b), or (c) of this 
section (as applicable) yields an SAB extension comprising at least 130 
contiguous square kilometers (50 contiguous square miles), the licensee 
must submit an application for major modification of the CGSA using FCC 
Form 601. See also Sec. Sec.  22.912, 22.949, and 22.953.
    (a) CGSA determination (non-PSD). For the purpose of calculating the 
SABs for cell sites and determining CGSA expansion areas for Cellular 
base stations that do not operate using PSD (as permitted under Sec.  
22.913), the distance to the SAB is calculated as a function of 
effective radiated power (ERP) and antenna center of radiation height 
above average terrain (HAAT), height above sea level (HASL), or height 
above mean sea level (HAMSL).
    (1) Except as provided in paragraphs (a)(2) and (b) of this section, 
the distance from a cell transmitting antenna to its SAB along each 
cardinal radial is calculated as follows:

d = 2.531 x h\0.34\ x p\0.17\

where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts

    (2) The distance from a cell transmitting antenna located in the 
Gulf of Mexico Service Area (GMSA) to its SAB along each cardinal radial 
is calculated as follows:


d = 6.895 x h\0.30\ x p\0.15\

Where:

d is the radial distance in kilometers
h is the radial antenna HAAT in meters
p is the radial ERP in Watts


[[Page 94]]


    (3) The value used for h in the formula in paragraph (a)(2) of this 
section must not be less than 8 meters (26 feet) HASL (or HAMSL, as 
appropriate for the support structure). The value used for h in the 
formula in paragraph (a)(1) of this section must not be less than 30 
meters (98 feet) HAAT, except that for unserved area applications 
proposing a cell with an ERP not exceeding 10 Watts, the value for h 
used in the formula in paragraph (a)(1) of this section to determine the 
service area boundary for that cell may be less than 30 meters (98 feet) 
HAAT, but not less than 3 meters (10 feet) HAAT.
    (4) The value used for p in the formulas in paragraphs (a)(1) and 
(a)(2) of this section must not be less than 0.1 Watt or 27 dB less than 
(1/500 of) the maximum ERP in any direction, whichever is more.
    (5) Whenever use of the formula in paragraph (a)(1) of this section 
pursuant to the exception contained in paragraph (a)(3) of this section 
results in a calculated distance that is less than 5.4 kilometers (3.4 
miles), the radial distance to the service area boundary is deemed to be 
5.4 kilometers (3.4 miles).
    (6) The distance from a cell transmitting antenna to the SAB along 
any radial other than the eight cardinal radials is calculated by linear 
interpolation of distance as a function of angle.
    (b) Alternative CGSA determination (non-PSD). If a carrier believes 
that the method described in paragraph (a) of this section produces a 
CGSA that departs significantly (20% in the 
service area of any cell) from the geographic area where reliable 
cellular service is actually provided, the carrier may submit, as an 
exhibit to an application for modification of the CGSA using FCC Form 
601, a depiction of what the carrier believes the CGSA should be. Such 
submissions must be accompanied by one or more supporting propagation 
studies using methods appropriate for the 800-900 MHz frequency range, 
including all supporting data and calculations, and/or by extensive 
field strength measurement data. For the purpose of such submissions, 
cellular service is considered to be provided in all areas, including 
``dead spots'', between the transmitter location and the locus of points 
where the predicted or measured median field strength finally drops to 
32 dB[micro]V/m (i.e. does not exceed 32 dB[micro]V/m further out). If, 
after consideration of such submissions, the FCC finds that adjustment 
to a CGSA is warranted, the FCC may grant the application.
    (1) The alternative CGSA determination must define the CGSA in terms 
of distances from the cell sites to the 32 dB[micro]V/m contour along 
the eight cardinal radials, with points in other azimuthal directions 
determined by the method given in paragraph (a)(6) of this section. The 
distances used must be representative of the coverage within the eight 
cardinal radials, as depicted by the alternative CGSA determination.
    (2) If an uncalibrated predictive model is used to depict the CGSA, 
the alternative CGSA determination must identify factors (e.g. terrain 
roughness or features) that could plausibly account for the difference 
between actual coverage and that defined by the formula in paragraph 
(a)(1) of this section. If actual measurements or a measurement-
calibrated predictive model are used to depict the CGSA, and this fact 
is disclosed in the alternative CGSA determination, it is not necessary 
to offer an explanation of the difference between actual coverage and 
that defined by the formula in paragraph (a)(1) of this section. If the 
formula in paragraph (a)(1) of this section is clearly inapplicable for 
the cell(s) in question (e.g. for microcells), this should be disclosed 
in the alternative CGSA determination.
    (3) The provision for alternative CGSA determinations was made in 
recognition that the formula in paragraph (a)(1) of this section is a 
general model that provides a reasonable approximation of coverage in 
most land areas, but may under-predict or over-predict coverage in 
specific areas with unusual terrain roughness or features, and may be 
inapplicable for certain purposes, e.g., cells with a coverage radius of 
less than 8 kilometers (5 miles). In such cases, alternative methods 
that utilize more specific models are appropriate. Accordingly, the FCC 
does not consider use of the formula in paragraph (a)(1) of this section 
with parameters outside

[[Page 95]]

of the limits in paragraphs (a)(3), (a)(4) and (a)(5) of this section or 
with data for radials other than the cardinal radials to be a valid 
alternative method for determining the CGSA of a cellular system.
    (c) CGSA determination (PSD). (1) For the purpose of calculating the 
SABs for cell sites and determining CGSA expansion areas for Cellular 
base stations that operate using PSD (as permitted under Sec.  22.913), 
the licensee must use a predictive propagation model that is appropriate 
for the service provided, taking into account terrain and local 
conditions. The SAB and CGSA boundary must be defined in terms of 
distances from the cell site to the 32 dB[micro]V/m contour along the 
eight cardinal radials, with points in other azimuthal directions 
determined by the method set forth in paragraph (a)(6) of this section. 
The distances used must be representative of the coverage within the 
eight cardinal radials.
    (2) An application for major modification of the CGSA under this 
paragraph (c) must include, as an exhibit, a depiction of the CGSA 
accompanied by one or more supporting propagation studies using methods 
appropriate for the 800-900 MHz frequency range, including all 
supporting data and calculations, and/or by extensive field strength 
measurement data. For the purpose of such submissions, Cellular service 
is considered to be provided in all areas, including ``dead spots,'' 
between the transmitter location and the locus of points where the 
predicted or measured median field strength finally drops to 32 
dB[micro]V/m (i.e., does not exceed 32 dB[micro]V/m further out). If, 
after consideration of such submissions, the FCC finds that adjustment 
to a CGSA is warranted, the FCC may grant the application.
    (d) Protection afforded. Cellular systems are entitled to protection 
only within the CGSA (as determined in accordance with this section) 
from co-channel and first-adjacent channel interference (see Sec.  
22.983). Licensees must cooperate in resolving co-channel and first-
adjacent channel interference by changing channels used at specific 
cells or by other technical means.

Sec.  22.912  Service area boundary extensions.

    This section contains rules governing service area boundary (SAB) 
extensions. SAB extensions are areas (calculated using the methodology 
of Sec.  22.911) that extend outside of the licensee's Cellular 
Geographic Service Area (CGSA) boundary into Unserved Area or into the 
CGSA of a neighboring co-channel licensee. Service within SAB extensions 
is not protected from interference or capture under Sec.  22.911(d) 
unless and until the area within the SAB extension becomes part of the 
CGSA in compliance with all applicable rules.
    (a) Extensions into Unserved Area. Subject to paragraph (c) of this 
section, the licensee of a Cellular system may, at any time, extend its 
SAB into Unserved Area and provide service on a secondary basis only, 
provided that the extension area comprises less than 130 contiguous 
square kilometers (50 contiguous square miles). If more than one 
licensee of a Cellular system extends into all or a portion of the same 
Unserved Area under this section, all such licensees may provide service 
in such Unserved Area on a shared secondary (unprotected) basis only.
    (b) Contract extensions. The licensee of any Cellular system may, at 
any time, enter into a contract with an applicant for, or a licensee of, 
a Cellular system on the same channel block to allow one or more SAB 
extensions into its CGSA (not into Unserved Area).
    (c) Gulf of Mexico Service Area. Land-based Cellular system 
licensees may not extend their SABs into the Gulf of Mexico Exclusive 
Zone (GMEZ) absent written contractual consent of the co-channel GMEZ 
licensee. GMEZ licensees may not extend their SABs into the CGSA of a 
licensee on the same channel block in an adjacent CMA or the Gulf of 
Mexico Coastal Zone absent written contractual consent of the co-channel 
licensee.

Sec.  22.913  Effective radiated power limits.

    Licensees in the Cellular Radiotelephone Service are subject to the 
effective radiated power (ERP) limits and other requirements in this 
Section. See also Sec.  22.169.
    (a) Maximum ERP. The ERP of transmitters in the Cellular 
Radiotelephone Service must not exceed the limits in this section.
    (1) Except as described in paragraphs (a)(2), (3), and (4) of this 
section, the ERP of base stations and repeaters must not exceed--
    (i) 500 watts per emission; or
    (ii) 400 watts/MHz (PSD) per sector.
    (2) Except as described in paragraphs (a)(3) and (4) of this 
section, for systems operating in areas more than 72 kilometers (45 
miles) from international borders that:
    (i) Are located in counties with population densities of 100 persons 
or fewer per square mile, based upon the most recently available 
population statistics from the Bureau of the Census; or
    (ii) Extend coverage into Unserved Area on a secondary basis (see 
Sec.  22.949), the ERP of base transmitters and repeaters must not 
exceed--
    (A) 1000 watts per emission; or
    (B) 800 watts/MHz (PSD) per sector.
    (3) Provided that they also comply with paragraphs (b) and (c) of 
this section, licensees are permitted to operate their base transmitters 
and repeaters with an ERP greater than 400 watts/MHz (PSD) per sector, 
up to a maximum ERP of 1000 watts/MHz (PSD) per sector unless they meet 
the conditions in paragraph (a)(4) of this section.
    (4) Provided that they also comply with paragraphs (b) and (c) of 
this section, licensees of systems operating in areas more than 72 
kilometers (45 miles) from international borders that:
    (i) Are located in counties with population densities of 100 persons 
or fewer per square mile, based upon the most recently available 
population statistics from the Bureau of the Census; or
    (ii) Extend coverage into Unserved Area on a secondary basis (see 
Sec.  22.949), are permitted to operate base transmitters and repeaters 
with an ERP greater than 800 watts/MHz (PSD) per sector, up to a maximum 
of 2000 watts/MHz (PSD) per sector.
    (5) The ERP of mobile transmitters and auxiliary test transmitters 
must not exceed 7 watts.
    (b) Power flux density (PFD). Until May 12, 2024, each Cellular base 
station that operates at the higher ERP limits permitted under 
paragraphs (a)(3) and (4) of this section must be designed and deployed 
so as not to exceed a modeled PFD of 3000 microwatts/m\2\/MHz over at 
least 98% of the area within 1 km of the base station antenna, at 1.6 
meters above ground level. To ensure its compliance with this 
requirement, the licensee must perform predictive modeling of the PFD 
values within at least 1 km of each base station antenna prior to 
commencing such operations and, thereafter, prior to making any site 
modifications that may increase the PFD levels around the base station. 
The modeling tools must take into consideration terrain and other local 
conditions and must use good engineering practices for the 800 MHz band.
    (c) Advance notification requirement. At least 30 days but not more 
than 90 days prior to activating a base station at the higher ERP limits 
permitted under paragraphs (a)(3) and (4) of this section, the Cellular 
licensee must provide written advance notice to any public safety 
licensee authorized in the frequency range 806-816 MHz/851-861 MHz with 
a base station located within a radius of 113 km of the Cellular base 
station to be deployed. The written notice shall be required only one 
time for each such cell site and is for informational purposes only; the 
public safety licensees are not afforded the right to accept or reject 
the activation or to unilaterally require changes in the operating 
parameters. The written notification must include the base station's 
location, ERP level, height of the transmitting antenna's center of 
radiation above ground level, and the timeframe for activation, as well 
as the Cellular licensee's contact information. Additional information 
shall be provided by the Cellular licensee upon request of a public 
safety licensee required to be notified under this paragraph (c). See 
also Sec. Sec.  22.970 through 22.973.
    (d) Power measurement. Measurement of the ERP of Cellular base 
transmitters and repeaters must be made using

[[Page 97]]

an average power measurement technique. The peak-to-average ratio (PAR) 
of the transmission must not exceed 13 dB. Power measurements for base 
transmitters and repeaters must be made in accordance with either of the 
following:
    (1) A Commission-approved average power technique (see FCC 
Laboratory's Knowledge Database); or
    (2) For purposes of this section, peak transmit power must be 
measured over an interval of continuous transmission using 
instrumentation calibrated in terms of an rms-equivalent voltage. The 
measurement results shall be properly adjusted for any instrument 
limitations, such as detector response times, limited resolution 
bandwidth capability when compared to the emission bandwidth, 
sensitivity, etc., so as to obtain a true peak measurement for the 
emission in question over the full bandwidth of the channel.
    (e) Height-power limit. The ERP of base transmitters must not exceed 
the amount that would result in an average distance to the service area 
boundary of 79.1 kilometers (49 miles) for Cellular systems authorized 
to serve the Gulf of Mexico MSA and 40.2 kilometers (25 miles) for all 
other Cellular systems. The average distance to the service area 
boundary is calculated by taking the arithmetic mean of the distances 
determined using the procedures specified in Sec.  22.911 for the eight 
cardinal radial directions.
    (f) Exemptions from height-power limit. Licensees need not comply 
with the height-power limit in paragraph (e) of this section if either 
of the following conditions is met:
    (1) The proposed operation is coordinated with the licensees of all 
affected Cellular systems on the same channel block within 121 
kilometers (75 miles) and concurrence is obtained; or
    (2) The licensee's base transmitter or repeater is operated at the 
ERP limits (W/MHz) specified above in paragraph (a)(1)(ii), (a)(2)(ii), 
(a)(3), or (a)(4) of this section.

Sec.  22.917  Emission limitations for cellular equipment.

    The rules in this section govern the spectral characteristics of 
emissions in the Cellular Radiotelephone Service.
    (a) Out of band emissions. The power of any emission outside of the 
authorized operating frequency ranges must be attenuated below the 
transmitting power (P) by a factor of at least 43 + 10 log(P) dB.
    (b) Measurement procedure. Compliance with these rules is based on 
the use of measurement instrumentation employing a reference bandwidth 
as follows:
    (1) In the spectrum below 1 GHz, instrumentation should employ a 
reference bandwidth of 100 kHz or greater. In the 1 MHz bands 
immediately outside and adjacent to the frequency block, a resolution 
bandwidth of at least one percent of the emission bandwidth of the 
fundamental emission of the transmitter may be employed. A narrower 
resolution bandwidth is permitted in all cases to improve measurement 
accuracy, provided that the measured power is integrated over the full 
required reference bandwidth (i.e., 100 kHz or 1 percent of emission 
bandwidth, as specified). The emission bandwidth is defined as the width 
of the signal between two points, one below the carrier center frequency 
and one above the carrier center frequency, outside of which all 
emissions are attenuated at least 26 dB below the transmitter power.
    (2) In the spectrum above 1 GHz, instrumentation should employ a 
reference bandwidth of 1 MHz.
    (c) Alternative out of band emission limit. Licensees in this 
service may establish an alternative out of band emission limit to be 
used at specified band edge(s) in specified geographical areas, in lieu 
of that set forth in this section, pursuant to a private contractual 
arrangement of all affected licensees and applicants. In this event, 
each party to such contract shall maintain a copy of the contract in 
their station files and disclose it to prospective assignees or 
transferees and, upon request, to the FCC.
    (d) Interference caused by out of band emissions. If any emission 
from a transmitter operating in this service results

[[Page 98]]

in interference to users of another radio service, the FCC may require a 
greater attenuation of that emission than specified in this section.

    Cellular licensees may apply to partition any portion of their 
licensed Cellular Geographic Service Area (CGSA) or to disaggregate 
their licensed spectrum at any time following the grant of their 
authorization(s). Parties seeking approval for partitioning and 
disaggregation shall request from the FCC an authorization for partial

Sec.  22.949  Unserved Area licensing; minimum coverage requirements.

    (a) The Unserved Area licensing process described in this section is 
on-going and applications may be filed at any time, subject to the 
following coverage requirements:
    (1) Applicants for authority to operate a new Cellular system or 
expand an existing Cellular Geographic Service Area (CGSA) in Unserved 
Area must propose a CGSA or CGSA expansion of

[[Page 99]]

at least 130 contiguous square kilometers (50 contiguous square miles) 
using the methodology of Sec.  22.911.
    (2) Applicants for authority to operate a new Cellular system must 
not propose coverage of water areas only (or water areas and uninhabited 
islands or reefs only), except for Unserved Area in the Gulf of Mexico 
Service Area.
    (b) There is no limit to the number of Unserved Area applications 
that may be granted on each channel block of each CMA that is subject to 
the procedures of this section. Consequently, Unserved Area applications 
are mutually exclusive only if the proposed CGSAs would overlap. 
Mutually exclusive applications are processed using the general 
procedures under Sec.  22.131.
    (c) Unserved Area applications under this section may propose a CGSA 
covering more than one CMA. Each Unserved Area application must request 
authorization for only one CGSA and must not propose a CGSA overlap with 
an existing CGSA.
    (d) Settlements among some, but not all, applicants with mutually 
exclusive applications for Unserved Area (partial settlements) under 
this section are prohibited. Settlements among all applicants with 
mutually exclusive applications under this section (full settlements) 
are allowed and must be filed no later than the date that the FCC Form 
175 (short-form) is filed.

Sec.  22.950  Provision of service in the Gulf of Mexico Service Area (GMSA).

    The GMSA has been divided into two areas for licensing purposes, the 
Gulf of Mexico Exclusive Zone (GMEZ) and the Gulf of Mexico Coastal Zone 
(GMCZ). This section describes these areas and sets forth the process 
for licensing facilities in these two respective areas within the GMSA.
    (a) The GMEZ and GMCZ are defined as follows:
    (1) Gulf of Mexico Exclusive Zone. The geographical area within the 
Gulf of Mexico Service Area that lies between the coastline line and the 
southern demarcation line of the Gulf of Mexico Service Area, excluding 
the area comprising the Gulf of Mexico Coastal Zone.
    (2) Gulf of Mexico Coastal Zone. The geographical area within the 
Gulf of Mexico Service Area that lies between the coast line of Florida 
and a line extending approximately twelve nautical miles due south from 
the coastline boundary of the States of Florida and Alabama, and 
continuing along the west coast of Florida at a distance of twelve 
nautical miles from the shoreline. The line is defined by Great Circle 
arcs connecting the following points (geographical coordinates listed as 
North Latitude, West Longitude) consecutively in the order listed:
    (i) 30[deg]16[min]49[sec] N 87[deg]31[min]06[sec] W
    (ii) 30[deg]04[min]35[sec] N 87[deg]31[min]06[sec] W
    (iii) 30[deg]10[min]56[sec] N 86[deg]26[min]53[sec] W
    (iv) 30[deg]03[min]00[sec] N 86[deg]00[min]29[sec] W
    (v) 29[deg]33[min]00[sec] N 85[deg]32[min]49[sec] W
    (vi) 29[deg]23[min]21[sec] N 85[deg]02[min]06[sec] W

    (viii) 28[deg]54[min]00[sec] N 83[deg]05[min]33[sec] W
    (ix) 28[deg]34[min]41[sec] N 82[deg]53[min]38[sec] W
    (x) 27[deg]50[min]39[sec] N 83[deg]04[min]27[sec] W
    (xi) 26[deg]24[min]22[sec] N 82[deg]23[min]22[sec] W
    (xii) 25[deg]41[min]39[sec] N 81[deg]49[min]40[sec] W
    (xiii) 24[deg]59[min]02[sec] N 81[deg]15[min]04[sec] W
    (xiv) 24[deg]44[min]23[sec] N 81[deg]57[min]04[sec] W
    (xv) 24[deg]32[min]37[sec] N 82[deg]02[min]01[sec] W
    (b) Service Area Boundary Calculation. The service area boundary of 
a cell site located within the Gulf of Mexico Service Area is calculated 
pursuant to Sec.  22.911(a)(2). Otherwise, the service area boundary is 
calculated pursuant to Sec.  22.911(a)(1) or Sec.  22.911(b).
    (c) Gulf of Mexico Exclusive Zone (GMEZ). GMEZ licensees have an 
exclusive right to provide Cellular service in the GMEZ, and may add, 
modify, or remove facilities anywhere within the GMEZ without prior FCC 
approval. There is no Unserved Area licensing procedure for the GMEZ.
    (d) Gulf of Mexico Coastal Zone (GMCZ). The GMCZ is subject to the 
Unserved Area licensing procedures set forth in Sec.  22.949.

Sec.  22.970  Unacceptable interference to part 90 non-cellular 800 MHz
licensees from cellular radiotelephone or part 90-800 MHz cellular systems.

    (a) Definition. Except as provided in 47 CFR 90.617(k), unacceptable 
interference to non-cellular part 90 licensees in the 800 MHz band from 
cellular radiotelephone or part 90-800 MHz cellular systems will be 
deemed to occur when the below conditions are met:
    (1) A transceiver at a site at which interference is encountered:
    (i) Is in good repair and operating condition, and is receiving:
    (A) A median desired signal of -104 dBm or higher, as measured at 
the R.F. input of the receiver of a mobile unit; or
    (B) A median desired signal of -101 dBm or higher, as measured at 
the R.F. input of the receiver of a portable i.e. hand-held unit; and, 
either
    (ii) Is a voice transceiver:
    (A) With manufacturer published performance specifications for the 
receiver section of the transceiver equal to, or exceeding, the minimum 
standards set out in paragraph (b) of this section, below; and;
    (B) Receiving an undesired signal or signals which cause the 
measured Carrier to Noise plus interference (C/(I + N)) ratio of the 
receiver section of said transceiver to be less than 20 dB, or,
    (iii) Is a non-voice transceiver receiving an undesired signal or 
signals which cause the measured bit error rate (BER) (or some 
comparable specification) of the receiver section of said transceiver to 
be more than the value reasonably designated by the manufacturer.
    (2) Provided, however, that if the receiver section of the mobile or 
portable voice transceiver does not conform to the standards set out in 
paragraph (b) of this section, then that transceiver shall be deemed 
subject to unacceptable interference only at sites where the median 
desired signal satisfies the applicable threshold measured signal

[[Page 102]]

power in paragraph (a)(1)(i) of this section after an upward adjustment 
to account for the difference in receiver section performance. The 
upward adjustment shall be equal to the increase in the desired signal 
required to restore the receiver section of the subject transceiver to 
the 20 dB C/(I + N) ratio of paragraph (a)(1)(ii)(B) of this section. 
The adjusted threshold levels shall then define the minimum measured 
signal power(s) in lieu of paragraphs (a)(1)(i) of this section at which 
the licensee using such non-compliant transceiver is entitled to 
interference protection.
    (b) Minimum receiver requirements. Voice transceivers capable of 
operating in the 806-824 MHz portion of the 800 MHz band shall have the 
following minimum performance specifications in order for the system in 
which such transceivers are used to claim entitlement to full protection 
against unacceptable interference (See paragraph (a) (2) of this 
section).
    (1) Voice units intended for mobile use: 75 dB intermodulation 
rejection ratio; 75 dB adjacent channel rejection ratio; -116 dBm 
reference sensitivity.
    (2) Voice units intended for portable use: 70 dB intermodulation 
rejection ratio; 70 dB adjacent channel rejection ratio; -116 dBm 
reference sensitivity.

Sec.  22.971  Obligation to abate unacceptable interference.

    (a) Strict Responsibility. Any licensee who, knowingly or 
unknowingly, directly or indirectly, causes or contributes to causing 
unacceptable interference to a non-cellular part 90 of this chapter 
licensee in the 800 MHz band, as defined in Sec.  22.970, shall be 
strictly accountable to abate the interference, with full cooperation 
and utmost diligence, in the shortest time practicable. Interfering 
licensees shall consider all feasible interference abatement measures, 
including, but not limited to, the remedies specified in the 
interference resolution procedures set forth in Sec.  22.972(c). This 
strict responsibility obligation applies to all forms of interference, 
including out-of-band emissions and intermodulation.
    (b) Joint and several responsibility. If two or more licensees 
knowingly or unknowingly, directly or indirectly, cause or contribute to 
causing unacceptable interference to a non-cellular part 90 of this 
chapter licensee in the 800 MHz band, as defined in Sec.  22.970, such 
licensees shall be jointly and severally responsible for abating 
interference, with full cooperation and utmost diligence, in the 
shortest practicable time.
    (1) This joint and several responsibility rule requires interfering 
licensees to consider all feasible interference abatement measures, 
including, but not limited to, the remedies specified in the 
interference resolution procedures set forth in Sec.  22.972(c). This 
joint and several responsibility rule applies to all forms of 
interference, including out-of-band emissions and intermodulation.
    (2) Any licensee that can show that its signal does not directly or 
indirectly, cause or contribute to causing unacceptable interference to 
a non-cellular part 90 of this chapter licensee in the 800 MHz band, as 
defined in this chapter, shall not be held responsible for resolving 
unacceptable interference. Notwithstanding, any licensee that receives 
an interference complaint from a public safety/CII licensee shall 
respond to such complaint consistent with the interference resolution 
procedures set forth in this chapter.

[69 FR 67834, Nov. 22, 2004, as amended at 70 FR 76707, Dec. 28, 2005]



Sec.  22.972  Interference resolution procedures.

    (a) Initial notification. (1) Cellular Radiotelephone licensees may 
receive initial notification of interference from non-cellular part 90 
of this chapter licensees in the 800 MHz band pursuant to Sec.  
90.674(a) of this chapter.
    (2) Cellular Radiotelephone licensees, in conjunction with part 90 
ESMR licensees, shall establish an electronic means of receiving the 
initial notification described in Sec.  90.674(a) of this chapter. The 
electronic system must be designed so that all appropriate Cellular 
Radiotelephone licensees and part 90 ESMR licensees can be contacted 
about the interference incident with a single notification. The 
electronic system for

[[Page 103]]

receipt of initial notification of interference complaints must be 
operating no later than February 22, 2005.
    (3) Cellular Radiotelephone licensees must respond to the initial 
notification described in Sec.  90.674(a) of this chapter, as soon as 
possible and no later than 24 hours after receipt of notification from a 
part 90 public safety/CII licensee. This response time may be extended 
to 48 hours after receipt from other part 90 non-cellular licensees 
provided affected communications on these systems are not safety 
related.
    (b) Interference analysis. Cellular Radiotelephone licensees--who 
receive an initial notification described in Sec.  90.674(a) of this 
chapter--shall perform a timely analysis of the interference to identify 
the possible source. Immediate on-site visits may be conducted when 
necessary to complete timely analysis. Interference analysis must be 
completed and corrective action initiated within 48 hours of the initial 
complaint from a part 90 of this chapter public safety/CII licensee. 
This response time may be extended to 96 hours after the initial 
complaint from other part 90 of this chapter non-cellular licensees 
provided affected communications on these systems are not safety 
related. Corrective action may be delayed if the affected licensee 
agrees in writing (which may be, but is not required to be, recorded via 
e-mail or other electronic means) to a longer period.
    (c) Mitigation steps. (1) All Cellular Radiotelephone and part 90 of 
this chapter--800 MHz cellular system licensees who are responsible for 
causing unacceptable interference shall take all affirmative measures to 
resolve such interference. Cellular Radiotelephone licensees found to 
contribute to unacceptable interference, as defined in Sec.  22.970, 
shall resolve such interference in the shortest time practicable. 
Cellular Radiotelephone licensees and part 90 of this chapter--800 MHz 
cellular system licensees must provide all necessary test apparatus and 
technical personnel skilled in the operation of such equipment as may be 
necessary to determine the most appropriate means of timely eliminating 
the interference. However, the means whereby interference is abated or 
the cell parameters that may need to be adjusted is left to the 
discretion of the Cellular Radiotelephone and/or part 90 of this 
chapter--800 MHz cellular system licensees, whose affirmative measures 
may include, but not be limited to, the following techniques:
    (i) Increasing the desired power of the public safety/CII signal;
    (ii) Decreasing the power of the part 90 ESMR and/or Cellular 
Radiotelephone system signal;
    (iii) Modifying the part 90 ESMR and/or Cellular Radiotelephone 
system antenna height;
    (iv) Modifying the part 90 ESMR and/or Cellular Radiotelephone 
system antenna characteristics;
    (v) Incorporating filters into part 90 ESMR and/or Cellular 
Radiotelephone transmission equipment;
    (vi) Permanently changing part 90 ESMR and/or Cellular 
Radiotelephone frequencies; and
    (vii) Supplying interference-resistant receivers to the affected 
public safety/CII licensee(s). If this technique is used, in all 
circumstances, Cellular Radiotelephone and/or part 90 of this chapter 
ESMR licensees shall be responsible for all costs thereof.
    (2) Whenever short-term interference abatement measures prove 
inadequate, the affected part 90 of this chapter non-cellular licensee 
shall, consistent with but not compromising safety, make all necessary 
concessions to accepting interference until a longer-term remedy can be 
implemented.
    (3) Discontinuing operations when clear imminent danger exists. When 
a part 90 of this chapter public safety licensee determines that a 
continuing presence of interference constitutes a clear and imminent 
danger to life or property, the licensee causing the interference must 
discontinue the associated operation immediately, until a remedy can be 
identified and applied. The determination that a continuing presence 
exists that constitutes a clear and imminent danger to life or property, 
must be made by written statement that:
    (i) Is in the form of a declaration, notarized affidavit, or 
statement under penalty or perjury, from an officer or executive of the 
affected public safety licensee;

[[Page 104]]

    (ii) Thoroughly describes the basis of the claim of clear and 
imminent danger;
    (iii) Was formulated on the basis of either personal knowledge or 
belief after due diligence;
    (iv) Is not proffered by a contractor or other third party; and
    (v) Has been approved by the Chief of the Public Safety and Homeland 
Security Bureau or other designated Commission official. Prior to the 
authorized official making a determination that a clear and imminent 
danger exists, the associated written statement must be served by hand-
delivery or receipted fax on the applicable offending licensee, with a 
copy transmitted by the fastest available means to the Washington, DC 
office of the Commission's Public Safety and Homeland Security Bureau.

Sec.  22.973  Information exchange.

    (a) Prior notification. Public safety/CII licensees may notify a 
part 90 ESMR or cellular radiotelephone licensee that they wish to 
receive prior notification of the activation or modification of part 90 
ESMR or cellular radiotelephone cell sites in their area. Thereafter, 
the part 90 ESMR or cellular radiotelephone licensee must provide the 
following information to the public safety/CII licensee at least 10 
business days before a new cell site is activated or an existing cell 
site is modified:
    (1) Location;
    (2) Effective radiated power;
    (3) Antenna height;
    (4) Channels available for use.
    (b) Purpose of prior notification. The prior coordination of cell 
sites is for informational purposes only. Public safety/CII licensees 
are not afforded the right to accept or reject the activation of a 
proposed cell or to unilaterally require changes in its operating 
parameters. The principal purposes of notification are to:
    (1) Allow a public safety licensee to advise the part 90 of this 
chapter ESMR or Cellular Radiotelephone licensee whether it believes a 
proposed cell will generate unacceptable interference;
    (2) Permit Cellular Radiotelephone or part 90 of this chapter ESMR 
licensees to make voluntary changes in cell parameters when a public 
safety licensee alerts them to possible interference; and
    (3) Rapidly identify the source if interference is encountered when 
the cell is activated.

Sec.  22.983  Field strength limit.

    (a) Subject to paragraphs (b) and (c) of this section, a licensee's 
predicted or measured median field strength limit must not exceed 40 
dB[micro]V/m at any given point along the Cellular Geographic Service 
Area (CGSA) boundary of a neighboring licensee on the same channel 
block, unless the affected licensee of the neighboring CGSA on the same 
channel block agrees to a different field strength. This also applies to 
CGSAs partitioned pursuant to Sec.  22.948.
    (b) Gulf of Mexico Service Area. Notwithstanding the field strength 
limit provision set forth in paragraph (a) of this section, licensees in 
or adjacent to the Gulf of Mexico Exclusive Zone are subject to Sec.  
22.912(c) regarding service area boundary extensions. See Sec.  
22.912(c).
    (c) Cellular licensees shall be subject to all applicable provisions 
and requirements of treaties and other international agreements between 
the United States government and the governments of Canada and Mexico, 
notwithstanding paragraphs (a) and (b) of this section.

                Subpart I_Offshore Radiotelephone Service



Sec.  22.1001  Scope.

    The rules in this subpart govern the licensing and operation of 
offshore radiotelephone stations. The licensing and operation of these 
stations and systems is also subject to rules elsewhere in this part 
that apply generally to the public mobile services. However, in case of 
conflict, the rules in this subpart govern.

[[Page 105]]



Sec.  22.1003  Eligibility.

    Any eligible entity (see Sec.  22.7) may apply for central station 
license(s) and/or offshore subscriber licenses under this subpart.

[70 FR 19312, Apr. 13, 2005]



Sec.  22.1005  Priority of service.

    Facilities in the Offshore Radiotelephone Service are intended 
primarily for rendition of public message service between offshore 
subscriber and central stations. However, they may also be used to 
render private leased line communication service, provided that such 
usage does not reduce or impair the extent or quality of communication 
service which would be available, in the absence of private leased line 
service, to the general public receiving or subsequently requesting 
public message service from an offshore central station.



Sec.  22.1007  Channels for offshore radiotelephone systems.

    The channels listed in this section are allocated for paired 
assignment to transmitters located in the specified geographical zones 
that provide offshore radiotelephone service. All channels have a 
bandwidth of 20 kHz and are designated by their center frequencies in 
MegaHertz.
    (a) Zone A--Southern Louisiana. The geographical area in Zone A is 
bounded as follows:

    From longitude W.87[deg]45[min] on the East to longitude 
W.94[deg]00[min] on the West and from the 4.8 kilometer (3 mile) limit 
along the Gulf of Mexico shoreline on the North to the limit of the 
Outer Continental Shelf on the South.

Sec.  22.1009  Transmitter locations.

    The rules in this section establish limitations on the locations 
from which stations in the Offshore Radiotelephone Service may transmit.
    (a) All stations. Offshore stations must not transmit from locations 
outside the boundaries of the appropriate zones specified in Sec.  
22.1007. Offshore stations must not transmit from locations within 241 
kilometers (150 miles) of any full-service television station that 
transmits on the TV channel containing the channel on which the offshore 
station transmits.
    (b) Airborne subscriber stations. Airborne subscriber stations must 
not transmit from altitudes exceeding 305 meters (1000 feet) above mean 
sea level. Airborne mobile stations in Zone A must not transmit from 
locations within 129 kilometers (80 miles) of Lake Charles, Louisiana. 
Airborne mobile stations in Zone B must not transmit from locations 
within 129 kilometers (80 miles) of Lafayette, Louisiana. Airborne 
mobile stations in Zone C must not transmit from locations within 129 
kilometers (80 miles) of Corpus Christi or locations within 129 
kilometers (80 miles) of Houston, Texas.



Sec.  22.1011  Antenna height limitations.

    The antenna height of offshore stations must not exceed 61 meters 
(200

[[Page 108]]

feet) above mean sea level. The antenna height of offshore surface 
mobile stations must not exceed 10 meters (30 feet) above the waterline.



Sec.  22.1013  Effective radiated power limitations.

    The effective radiated power (ERP) of transmitters in the Offshore 
Radiotelephone Service must not exceed the limits in this section.
    (a) Maximum power. The ERP of transmitters in this service must not 
exceed 1000 Watts under any circumstances.
    (b) Mobile transmitters. The ERP of mobile transmitters must not 
exceed 100 Watts. The ERP of mobile transmitters, when located within 32 
kilometers (20 miles) of the 4.8 kilometer (3 mile) limit, must not 
exceed 25 Watts. The ERP of airborne mobile stations must not exceed 1 
Watt.
    (c) Protection for TV Reception. The ERP limitations in this 
paragraph are intended to reduce the likelihood that interference to 
television reception from offshore radiotelephone operations will occur.
    (1) Co-channel protection. The ERP of offshore stations must not 
exceed the limits in Table I-1 of this section. The limits depend upon 
the height above mean sea level of the offshore transmitting antenna and 
the distance between the antenna location of the offshore transmitter 
and the antenna location of the main transmitter of the nearest full-
service television station that transmits on the TV channel containing 
the channel on which the offshore station transmits.
    (2) Adjacent channel protection. The ERP of offshore stations 
located within 128.8 kilometers (80 miles) of the main transmitter 
antenna of a full service TV station that transmits on a TV channel 
adjacent to the TV channel which contains the channel on which the 
offshore station transmits must not exceed the limits in the Table I-2 
of Sec.  22.1015. The limits depend upon the height above mean sea level 
of the offshore transmitting antenna and the distance between the 
location of the offshore transmitter and the 4.8 kilometer (3 mile) 
limit.

[[Page 109]]



Sec.  22.1031  Temporary fixed stations.

    The FCC may, upon proper application therefor, authorize the 
construction and operation of temporary fixed stations in the Offshore 
Radiotelephone service to be used only when the service of permanent 
fixed stations is disrupted by storms or emergencies or is otherwise 
unavailable.
    (a) Six month limitation. If it is necessary for a temporary fixed 
station to remain at the same location for more than six months, the 
licensee of that station must apply for authorization to operate the 
station at the specific location at least 30 days before the end of the 
six month period.
    (b) International communications. Communications between the United 
States and Mexico must not be carried using a temporary fixed station 
without prior authorization from the FCC. Licensees desiring to carry 
such communications should apply sufficiently in advance to allow for 
the time necessary to coordinate with Canada or Mexico.



Sec.  22.1035  Construction period.

    The construction period (see Sec.  22.142) for offshore stations is 
18 months.

Sec.  24.103  Construction requirements.

    (a) Nationwide narrowband PCS licensees shall construct base 
stations that provide coverage to a composite area of 750,000 square 
kilometers or

[[Page 115]]

serve 37.5 percent of the U.S. population within five years of initial 
license grant date; and, shall construct base stations that provide 
coverage to a composite area of 1,500,000 square kilometers or serve 75 
percent of the U.S. population within ten years of initial license grant 
date. Licensees may, in the alternative, provide substantial service to 
the licensed area as provided in paragraph (d) of this section.
    (b) Regional narrowband PCS licensees shall construct base stations 
that provide coverage to a composite area of 150,000 square kilometers 
or serve 37.5 percent of the population of the service area within five 
years of initial license grant date; and, shall construct base stations 
that provide coverage to a composite area of 300,000 square kilometers 
or serve 75 percent of the service area population within ten years of 
initial license grant date. Licensees may, in the alternative, provide 
substantial service to the licensed area as provided in paragraph (d) of 
this section.
    (c) MTA narrowband PCS licensees shall construct base stations that 
provide coverage to a composite area of 75,000 square kilometers or 25 
percent of the geographic area, or serve 37.5 percent of the population 
of the service area within five years of initial license grant date; 
and, shall construct base stations that provide coverage to a composite 
area of 150,000 square kilometers or 50 percent of the geographic area, 
or serve 75 percent of the population of the service area within ten 
years of initial license grant date. Licensees may, in the alternative, 
provide substantial service to the licensed area as provided in 
paragraph (d) of this section.
    (d) As an alternative to the requirements of paragraphs (a), (b), 
and (c) of this section, narrowband PCS licensees may demonstrate that, 
no later than ten years after the initial grant of their license, they 
provide substantial service to their licensed area. Licensees choosing 
this option must notify the FCC by filing FCC Form 601, no later than 15 
days after the end of the five year period following the initial grant 
of their license, that they plan to satisfy the alternative requirement 
to provide substantial service. ``Substantial service'' is defined as 
service that is sound, favorable, and substantially above a level of 
mediocre service that would barely warrant renewal.
    (e) In demonstrating compliance with the construction requirements 
set forth in this section, licensees must base their calculations on 
signal field strengths that ensure reliable service for the technology 
utilized. Licensees may determine the population of geographic areas 
included within their service contours using either the 1990 census or 
the 2000 census, but not both.
    (1) For the purpose of this section, the service radius of a base 
station may be calculated using the following formula:

dkm = 2.53 x hm0.34 x p\0.17\

where dkm is the radial distance in kilometers,
hm is the antenna HAAT of the base station in meters, and
p is the e.r.p. of the base station in watts.

    (2) Alternatively, licensees may use any service radius contour 
formula developed or generally used by industry, provided that such 
formula is based on the technical characteristics of their system.
    (f) Upon meeting the five and ten year benchmarks in paragraphs (a), 
(b), and (c) of this section, or upon meeting the substantial service 
alternative in paragraph (d), licensees shall notify the Commission by 
filing FCC Form 601 and including a map and other supporting 
documentation that demonstrate the required geographic area coverage, 
population coverage, or substantial service to the licensed area. The 
notification must be filed with the Commission within 15 days of the 
expiration of the relevant period.
    (g) If the sale of a license is approved, the new licensee is held 
to the original build-out requirement.
    (h) Failure by a licensee to meet the above construction 
requirements shall result in forfeiture of the license and ineligibility 
to regain it.

Sec.  24.104  Partitioning and disaggregation.

    Nationwide, regional, and MTA licensees may apply to partition their

[[Page 116]]

authorized geographic service area or disaggregate their authorized 
spectrum at any time following grant of their geographic area 
authorizations.
    (a) Application required. Parties seeking approval for partitioning 
and/or disaggregation shall apply for partial assignment of a license 
pursuant to Sec.  1.948 of this chapter.
    (b) Partitioning. In the case of partitioning, applicants and 
licensees must file FCC Form 603 pursuant to Sec.  1.948 of this chapter 
and describe the partitioned service area on a schedule to the 
application. The partitioned service area shall be defined by up to 120 
sets of geographic coordinates at points at every 3 degrees azimuth from 
a point within the partitioned service area along the partitioned 
service area boundary unless either an FCC-recognized service area is 
used (e.g., MEA or EA) or county lines are followed. The geographical 
coordinates must be specified in degrees, minutes, and seconds to the 
nearest second latitude and longitude, and must be based upon the 1983 
North American Datum (NAD83). In the case where FCC-recognized service 
areas or county lines are used, applicants need only list the specific 
area(s) through use of FCC designations or county names that constitute 
the partitioned area.
    (c) Disaggregation. Spectrum may be disaggregated in any amount.
    (d) Combined partitioning and disaggregation. Licensees may apply 
for partial assignment of authorizations that propose combinations of 
partitioning and disaggregation.
    (e) License term. The license term for a partitioned license area 
and for disaggregated spectrum shall be the remainder of the original 
licensee's license term as provided for in Sec.  1.955 of this chapter.

Sec.  24.134  Co-channel separation criteria.

    The minimum co-channel separation distance between base stations in 
different service areas is 113 kilometers (70 miles). A co-channel 
separation distance is not required for the base stations of the same 
licensee or when the affected parties have agreed to other co-channel 
separation distances.



Sec.  24.135  Frequency stability.

    (a) The frequency stability of the transmitter shall be maintained 
within 0.0001 percent (1 
ppm) of the center frequency over a temperature variation of -30 
[deg]Celsius to + 50 [deg]Celsius at normal supply voltage, and over a 
variation in the primary supply voltage of 85 percent to 115 percent of 
the rated supply voltage at a temperature of 20 [deg]Celsius.
    (b) For battery operated equipment, the equipment tests shall be 
performed using a new battery without any further requirement to vary 
supply voltage.
    (c) It is acceptable for a transmitter to meet this frequency 
stability requirement over a narrower temperature range provided the 
transmitter ceases to function before it exceeds these frequency 
stability limits.

Sec.  24.203  Construction requirements.

    (a) Licensees of 30 MHz blocks must serve with a signal level 
sufficient to provide adequate service to at least one-third of the 
population in their licensed area within five years of being licensed 
and two-thirds of the population in their licensed area within ten years 
of being licensed. Licensees may, in the alternative, provide 
substantial service to their licensed area within the appropriate five- 
and ten-year benchmarks. Licensees may choose to define population using 
the 1990 census or the 2000 census. Failure by any licensee to meet 
these requirements will result in forfeiture or non-renewal of the 
license and the licensee will be ineligible to regain it.
    (b) Licensees of 10 MHz blocks except for the 1910-1915 MHz and 
1990-1995 MHz, including 10 MHz C block licenses reconfigured pursuant 
to Amendment of the Commission's Rules Regarding Installment Payment 
Financing for Personal Communications Services (PCS) Licensees, WT 
Docket No. 97-82, Sixth Report and Order, FCC 00-313, and 15 MHz blocks 
resulting from the disaggregation option as provided in the Commission's 
Rules Regarding Installment Payment Financing for Personal 
Communications Services (PCS) Licensees, Second Report and Order and 
Further Notice of Proposed Rule Making, WT Docket 97-82, 12 FCC Rcd 
16436 (1997), as modified by Order on Reconsideration of the Second 
Report and Order, WT Docket 97-82, 13 FCC Rcd 8345 (1998), must serve 
with a signal level sufficient to provide adequate service to at least 
one-quarter of the population in their licensed area within five years 
of being licensed, or make a showing of substantial service in their 
licensed area within five years of being licensed. Population is defined 
as the 1990 population census. Licensees may elect to use the 2000 
population census to determine the five-year construction requirement. 
Failure by any licensee to meet these requirements will result in 
forfeiture of the license and the licensee will be ineligible to regain 
it.
    (c) Licensees must file maps and other supporting documents showing 
compliance with the respective construction requirements within the 
appropriate five- and ten-year benchmarks of the date of their initial 
licenses.
    (d) Licensees in the paired 1910-1915 MHz and 1990-1995 MHz bands 
must make a showing of ``substantial service'' in their license area 
within ten years of the date of initial license

[[Page 120]]

issuance or renewal. ``Substantial service'' is defined as service which 
is sound, favorable, and substantially above a level of mediocre service 
which just might minimally warrant renewal. Failure by any licensee to 
meet this requirement will result in forfeiture of the license and the 
licensee will be ineligible to regain it.

    (c) Mobile and portable stations are limited to 2 watts EIRP and the 
equipment must employ a means for limiting power to the minimum 
necessary for successful communications.
    (d) Power measurements for transmissions by stations authorized 
under this section may be made either in accordance with a Commission-
approved average power technique or in compliance with paragraph (e) of 
this section. In both instances, equipment employed must be authorized 
in accordance with the provisions of Sec.  24.51. In measuring 
transmissions in this band using an average power technique, the peak-
to-average ratio (PAR) of the transmission may not exceed 13 dB.
    (e) Peak transmit power must be measured over any interval of 
continuous transmission using instrumentation calibrated in terms of an 
rms-equivalent voltage. The measurement results shall be properly 
adjusted for any instrument limitations, such as detector response 
times, limited resolution bandwidth capability when compared to the 
emission bandwidth, sensitivity, etc., so as to obtain a true peak 
measurement for the emission in question over the full bandwidth of the 
channel.

    Note to Sec.  24.232: Height above average terrain (HAAT) is to be 
calculated using the method set forth in Sec.  24.53 of this part.

[73 FR 24183, May 2, 2008]



Sec.  24.235  Frequency stability.

    The frequency stability shall be sufficient to ensure that the 
fundamental emission stays within the authorized frequency block.



Sec.  24.236  Field strength limits.

    The predicted or measured median field strength at any location on 
the border of the PCS service area shall not exceed 47 dBuV/m unless the 
parties agree to a higher field strength.



Sec.  24.237  Interference protection.

    (a) All licensees are required to coordinate their frequency usage 
with the co-channel or adjacent channel incumbent fixed microwave 
licensees in the 1850-1990 MHz band. Coordination must occur before 
initiating operations from any base station. Problems that

[[Page 122]]

arise during the coordination process are to be resolved by the parties 
to the coordination. Licensees are required to coordinate with all users 
possibly affected, as determined by appendix I to this subpart E 
(Appendix E of the Memorandum Opinion and Order, GEN Docket No. 90-314, 
FCC 94-144; TIA Telecommunications Systems Bulletin 10-F, ``Interference 
Criteria for Microwave Systems,'' May 1994, (TSB10-F)); or an 
alternative method agreed to by the parties.
    (b) The results of the coordination process need to be reported to 
the Commission only if the parties fail to agree. Because broadband PCS 
licensees are required to protect fixed microwave licensees in the 1850-
1990 MHz band, the Commission will be involved in the coordination 
process only upon complaint of interference from a fixed microwave 
licensee. In such a case, the Commission will resolve the issues.
    (c) In all other respects, coordination procedures are to follow the 
requirements of Sec.  101.103(d) of this chapter to the extent that 
these requirements are not inconsistent with those specified in this 
part.
    (d) The licensee must perform an engineering analysis to assure that 
the proposed facilities will not cause interference to existing OFS 
stations within the coordination distance specified in Table 3 of a 
magnitude greater than that specified in the criteria set forth in 
paragraphs (e) and (f) of this section, unless there is prior agreement 
with the affected OFS licensee. Interference calculations shall be based 
on the sum of the power received at the terminals of each microwave 
receiver from all of the applicant's current and proposed PCS 
operations.

protection criterion shall be such that the interfering signal will not 
produce more than 1.0 dB degradation of the practical threshold of the 
microwave receiver for analog system, or such that the interfering 
signal will not cause an increase in the bit error rate (BER) from 10E-6 
to 10E-5 for digital systems.
    (g) The development of the C/I ratios and interference criteria 
specified in paragraphs (e) and (f) of this section and the methods 
employed to compute the interfering power at the microwave receivers 
shall follow generally acceptable good engineering practices. The 
procedures described for computing interfering signal levels in 
(appendix I to this subpart E Appendix E of the Memorandum Opinion and 
Order, GEN Docket No. 90-314, FCC 94-144) shall be applied. 
Alternatively, procedures for determining interfering signal levels

[[Page 123]]

and other criteria as may be developed by the Electronics Industries 
Association (EIA), the Institute of Electrical and Electronics 
Engineers, Inc. (IEEE), the American National Standards Institute (ANSI) 
or any other recognized authority will be acceptable to the Commission.

Sec.  24.238  Emission limitations for Broadband PCS equipment.

    The rules in this section govern the spectral characteristics of 
emissions in the Broadband Personal Communications Service.
    (a) Out of band emissions. The power of any emission outside of the 
authorized operating frequency ranges must be attenuated below the 
transmitting power (P) by a factor of at least 43 + 10 log(P) dB.
    (b) Measurement procedure. Compliance with these rules is based on 
the use of measurement instrumentation employing a resolution bandwidth 
of 1 MHz or greater. However, in the 1 MHz bands immediately outside and 
adjacent to the frequency block a resolution bandwidth of at least one 
percent of the emission bandwidth of the fundamental emission of the 
transmitter may be employed. A narrower resolution bandwidth is 
permitted in all cases to improve measurement accuracy provided the 
measured power is integrated over the full required measurement 
bandwidth (i.e. 1 MHz or 1 percent of emission bandwidth, as specified). 
The emission bandwidth is defined as the width of the signal between two 
points, one below the carrier center frequency and one above the carrier 
center frequency, outside of which all emissions are attenuated at least 
26 dB below the transmitter power.
    (c) Alternative out of band emission limit. Licensees in this 
service may establish an alternative out of band emission limit to be 
used at specified band edge(s) in specified geographical areas, in lieu 
of that set forth in this section, pursuant to a private contractual 
arrangement of all affected licensees and applicants. In this event, 
each party to such contract shall maintain a copy of the contract in 
their station files and disclose it to prospective assignees or 
transferees and, upon request, to the FCC.
    (d) Interference caused by out of band emissions. If any emission 
from a transmitter operating in this service results in interference to 
users of another radio service, the FCC may require a greater 
attenuation of that emission than specified in this section.

   Policies Governing Microwave Relocation From the 1850-1990 MHz Band



Sec.  24.239  Cost-sharing requirements for broadband PCS.

    Frequencies in the 1850-1990 MHz band listed in Sec.  101.147(c) of 
this chapter have been allocated for use by PCS. In accordance with 
procedures specified in Sec. Sec.  101.69 through 101.81 of this 
chapter, PCS entities (both licensed and unlicensed) are required to 
relocate the existing Fixed Microwave Services (FMS) licensees in these 
bands if interference to the existing FMS operations would occur. All 
PCS entities who benefit from spectrum clearance by other PCS entities 
or a voluntarily relocating microwave incumbent, must contribute to such 
relocation costs. PCS entities may satisfy this requirement by entering 
into private cost-sharing agreements or agreeing to terms other than 
those specified in Sec.  24.243. However, PCS entities are required to 
reimburse other PCS entities or voluntarily relocating microwave 
incumbents that incur relocation costs and are not parties to the 
alternative agreement. In addition, parties to a private cost-sharing 
agreement may seek reimbursement through the clearinghouse (as discussed 
in Sec.  24.241) from PCS entities that are not parties to the 
agreement. The cost-sharing plan is in effect during all phases of 
microwave relocation specified in Sec.  101.69 of this chapter. If a 
licensee in the Broadband PCS Service enters into a spectrum leasing 
arrangement (as set forth in part 1, subpart X of this chapter) and the 
spectrum lessee triggers a cost-sharing obligation,

[[Page 124]]

the licensee is the PCS entity responsible for satisfying the cost-
sharing obligations under Sec. Sec.  24.239 through 24.253.

[62 FR 12757, Mar. 18, 1997, as amended at 69 FR 77559, Dec. 27, 2004]



Sec.  24.241  Administration of the Cost-Sharing Plan.

    The Wireless Telecommunications Bureau, under delegated authority, 
will select an entity to operate as a neutral, not-for-profit 
clearinghouse. This clearinghouse will administer the cost-sharing plan 
by, inter alia, maintaining all of the cost and payment records related 
to the relocation of each link and determining the cost-sharing 
obligation of subsequent PCS entities. The cost-sharing rules will not 
take effect until an administrator is selected.

[61 FR 29691, June 12, 1996]



Sec.  24.243  The cost-sharing formula.

    A PCS relocator who relocates an interfering microwave link, i.e. 
one that is in all or part of its market area and in all or part of its 
frequency band or a voluntarily relocating microwave incumbent, is 
entitled to pro rata reimbursement based on the following formula:
[GRAPHIC] [TIFF OMITTED] TR12JN96.001


    (a) RN equals the amount of reimbursement.
    (b) C equals the actual cost of relocating the link. Actual 
relocation costs include, but are not limited to, such items as: Radio 
terminal equipment (TX and/or RX--antenna, necessary feed lines, MUX/
Modems); towers and/or modifications; back-up power equipment; 
monitoring or control equipment; engineering costs (design/path survey); 
installation; systems testing; FCC filing costs; site acquisition and 
civil works; zoning costs; training; disposal of old equipment; test 
equipment (vendor required); spare equipment; project management; prior 
coordination notification under Sec.  101.103(d) of this chapter; site 
lease renegotiation; required antenna upgrades for interference control; 
power plant upgrade (if required); electrical grounding systems; Heating 
Ventilation and Air Conditioning (HVAC) (if required); alternate 
transport equipment; and leased facilities. C also includes voluntarily 
relocating microwave incumbent's independent third party appraisal of 
its compensable relocation costs and incumbent transaction expenses that 
are directly attributable to the relocation, subject to a cap of two 
percent of the ``hard'' costs involved. C may not exceed $250,000 per 
link, with an additional $150,000 permitted if a new or modified tower 
is required.
    (c) N equals the number of PCS entities that would have interfered 
with the link. For the PCS relocator, N = 1. For the next PCS entity 
that would have interfered with the link, N = 2, and so on. In the case 
of a voluntarily relocating microwave incumbent, N = 1 for the first PCS 
entity that would have interfered with the link. For the next PCS entity 
that would have interfered with the link, N = 2, and so on.
    (d) Tm equals the number of months that have elapsed between the 
month the PCS relocator or voluntarily relocating microwave incumbent 
obtains reimbursement rights for the link and the month that the 
clearinghouse notifies a later-entrant of its reimbursement obligation 
for the link. A PCS relocator obtains reimbursement rights for the link 
on the date that it signs a relocation agreement with a microwave 
incumbent. A voluntarily relocating microwave incumbent obtains 
reimbursement rights for the link on the date that the incumbent 
notifies the Commission that it intends to discontinue, or has 
discontinued, the use of the link, pursuant to Sec.  101.305 of the 
Commission's rules.

[62 FR 12757, Mar. 18, 1997, as amended at 65 FR 46113, July 27, 2000]



Sec.  24.245  Reimbursement under the Cost-Sharing Plan.

    (a) Registration of reimbursement rights. (1) To obtain 
reimbursement, a PCS relocator must submit documentation of the 
relocation agreement to the clearinghouse within ten business days of 
the date a relocation agreement is signed with an incumbent.
    (2) To obtain reimbursement, a voluntarily relocating microwave 
incumbent must submit documentation of

[[Page 125]]

the relocation of the link to the clearinghouse within ten business days 
of the date that the incumbent notifies the Commission that it intends 
to discontinue, or has discontinued, the use of the link, pursuant to 
Sec.  101.305 of the Commission's rules.
    (b) Documentation of expenses. Once relocation occurs, the PCS 
relocator or the voluntarily relocating microwave incumbent, must submit 
documentation itemizing the amount spent for items listed in Sec.  
24.243(b). The voluntarily relocating microwave incumbent, must also 
submit an independent third party appraisal of its compensable 
relocation costs. The appraisal should be based on the actual cost of 
replacing the incumbent's system with comparable facilities and should 
exclude the cost of any equipment upgrades or items outside the scope of 
Sec.  24.243(b). The PCS relocator or the voluntarily relocating 
microwave incumbent, must identify the particular link associated with 
appropriate expenses (i.e., costs may not be averaged over numerous 
links). If a PCS relocator pays a microwave incumbent a monetary sum to 
relocate its own facilities, the PCS relocator must estimate the costs 
associated with relocating the incumbent by itemizing the anticipated 
cost for items listed in Sec.  24.243(b). If the sum paid to the 
incumbent cannot be accounted for, the remaining amount is not eligible 
for reimbursement. A PCS relocator may submit receipts or other 
documentation to the clearinghouse for all relocation expenses incurred 
since April 5, 1995.
    (c) Full reimbursement. A PCS relocator who relocates a microwave 
link that is either fully outside its market area or its licensed 
frequency band may seek full reimbursement through the clearinghouse of 
compensable costs, up to the reimbursement cap as defined in Sec.  
24.243(b). Such reimbursement will not be subject to depreciation under 
the cost-sharing formula.

[61 FR 29692, June 12, 1996, as amended at 62 FR 12757, Mar. 18, 1997; 
65 FR 46113, July 27, 2000]



Sec.  24.247  Triggering a reimbursement obligation.

    (a) Licensed PCS. The clearinghouse will apply the following test to 
determine if a PCS entity preparing to initiate operations must pay a 
PCS relocator or a voluntarily relocating microwave incumbent in 
accordance with the formula detailed in Sec.  24.243:
    (1) All or part of the relocated microwave link was initially co-
channel with the licensed PCS band(s) of the subsequent PCS entity;
    (2) A PCS relocator has paid the relocation costs of the microwave 
incumbent; and
    (3) The subsequent PCS entity is preparing to turn on a fixed base 
station at commercial power and the fixed base station is located within 
a rectangle (Proximity Threshold) described as follows:
    (i) The length of the rectangle shall be x where x is a line 
extending through both nodes of the microwave link to a distance of 48 
kilometers (30 miles) beyond each node. The width of the rectangle shall 
be y where y is a line perpendicular to x and extending for a distance 
of 24 kilometers (15 miles) on both sides of x. Thus, the rectangle is 
represented as follows:

[[Page 126]]

[GRAPHIC] [TIFF OMITTED] TC01MR91.041

    (ii) If the application of the Proximity Threshold test indicates 
that a reimbursement obligation exists, the clearinghouse will calculate 
the reimbursement amount in accordance with the cost-sharing formula and 
notify the subsequent PCS entity of the total amount of its 
reimbursement obligation.
    (b) Unlicensed PCS. UTAM's reimbursement obligation is triggered 
either:
    (1) When a county is cleared of microwave links in the unlicensed 
allocation, and UTAM invokes a Zone 1 power cap as a result of third 
party relocation activities; or
    (2) A county is cleared of microwave links in the unlicensed 
allocation and UTAM reclassifies a Zone 2 county to Zone 1 status.
    (c) Any new entrants granted licenses for the 1910-1915 MHz band 
must reimburse UTAM a pro rata share of its total expenses incurred by 
UTAM as of the date that the new entrants gain access to the band. The 
percent required by new entrants to pay shall be calculated based upon 
the amount of spectrum granted to the new entrant as compared to the 
total amount of spectrum UTAM is responsible for clearing of incumbents 
(20 megahertz), and must be paid before a new entrant begins operations 
in the band. For example, if a new entrant obtains a license for 5 
megahertz of spectrum in this band, it is required to reimburse UTAM 
one-quarter of UTAM's total costs to date on a pro rata shared basis. 
New entrants will be responsible for the actual costs associated with 
future relocation activities in their licensed spectrum, but will be 
entitled to seek reimbursement from UTAM for the proportion of those 
band clearing costs that benefit users of the 1915-1930 MHz band.

[61 FR 29692, June 12, 1996, as amended at 62 FR 12757, Mar. 18, 1997; 
69 FR 67836, Nov. 22, 2004]



Sec.  24.249  Payment issues.

    (a) Timing. On the day that a PCS entity files its prior 
coordination notice (PCN) in accordance with Sec.  101.103(d) of this 
chapter, it must file a copy of the PCN with the clearinghouse. The 
clearinghouse will determine if any reimbursement obligation exists and 
notify the PCS entity in writing of its repayment obligation, if any. 
When the PCS entity receives a written copy of such obligation, it must 
pay directly to the PCS relocator or the voluntarily relocating 
microwave incumbent the amount owed within thirty days, with the 
exception of those businesses that qualify for installment payments. A 
business that qualifies for an installment payment plan must make its 
first installment payment within thirty days of notice from the 
clearinghouse. UTAM's first payment will be due thirty days after its 
reimbursement obligation is triggered, as described in Sec.  24.247(b).
    (b) Eligibility for Installment Payments. PCS licensees that are 
allowed to pay for their licenses in installments under

[[Page 127]]

our designated entity rules will have identical payment options 
available to them with respect to payments under the cost-sharing plan. 
The specific terms of the installment payment mechanism, including the 
treatment of principal and interest, are the same as those applicable to 
the licensee's installment auction payments. If, for any reason, the 
entity eligible for installment payments is no longer eligible for such 
installment payments on its license, that entity is no longer eligible 
for installment payments under the cost-sharing plan. UTAM may make 
quarterly payments over a five-year period with an interest rate of 
prime plus 2.5 percent. UTAM may also negotiate separate repayment 
arrangements with other parties.

[61 FR 29693, June 12, 1996, as amended at 62 FR 12757, Mar. 18, 1997]



Sec.  24.251  Dispute resolution under the Cost-Sharing Plan.

    Disputes arising out of the cost-sharing plan, such as disputes over 
the amount of reimbursement required, must be brought, in the first 
instance, to the clearinghouse for resolution. To the extent that 
disputes cannot be resolved by the clearinghouse, parties are encouraged 
to use expedited ADR procedures, such as binding arbitration, mediation, 
or other ADR techniques.

[61 FR 29693, June 12, 1996]



Sec.  24.253  Termination of cost-sharing obligations.

    The cost-sharing plan will sunset for all PCS entities on April 4, 
2005, which is ten years after the date that voluntary negotiations 
commenced for A and B block PCS entities. Those PCS entities that are 
paying their portion of relocation costs on an installment basis must 
continue the payments until the obligation is satisfied.

[61 FR 29693, June 12, 1996]



Sec. Appendix I to Subpart E of Part 24--A Procedure for Calculating PCS 
   Signal Levels at Microwave Receivers (Appendix E of the Memorandum 
                           Opinion and Order)

    The new Rules adopted in Part 24 stipulate that estimates of 
interference to fixed microwave operations from a PCS operation will be 
based on the sum of signals received at a microwave receiver from the 
PCS operation. This appendix describes a procedure for computing this 
PCS level.
    In general, the procedure involves four steps:
    1. Determine the geographical coordinates of all microwave receivers 
operating on co-channel and adjacent frequencies within the coordination 
distance of each base station and the characteristics of each receiver, 
i.e., adjacent channel susceptibility, antenna gain, pattern and height, 
and line and other losses.
    2. Determine an equivalent isotropically radiated power (e.i.r.p.) 
for each base station and equivalent e.i.r.p. values for the mobiles and 
portables associated with each base station. Determine the values of 
pertinent correction and weighting factors based on building heights and 
density and distribution of portables. Close-in situations, prominent 
hills, and extra tall buildings require special treatment.
    3. Based on PCS e.i.r.p. values, correction and weighting factors, 
and microwave receiving system characteristics determined above, 
calculate the total interference power at the input of each microwave 
receiver, using the Longley-Rice propagation model.
    4. Based on the interference power level computed in step 3, 
determine interference to each microwave receiver using criteria 
described in Part 24 and EIA/TIA Bulletin 10-F.
    The interference from each base station and the mobiles and 
portables associated with it is calculated as follows:

Prbi = 10Log (ptbi)-Lbi-UCi 
          + Gmwi-Ci-BPi
Prmi = 10Log (nmi x ptmi)-
          Lmi-UCi + Gmwi-Ci
Prpsi = 10Log (npsi x ptpsi)-
          Lpsi-UCi + Gmwi-Ci
Prpbi = 10Log (npbi x ptpbi)-
          Lpbi-UCi-(BPi-BHi) 
          + Gmwi-Ci
Prpri = 10Log (npri x ptpri)-
          Lpri-(UCi-BHi) + 
          Gmwi-Ci

where:

P refers to Power in dBm
p refers to power in milliwatts
Prbi = Power at MW receiver from ith base station in dBm
ptbi = e.i.r.p. transmitted from ith base station in 
          milliwatts, which equals average power per channel x number of 
          channels x antenna gain with respect to an isotropic antenna - 
          line loss
Lbi = Path loss between MW and base station site in dB
UCi = Urban correction factor in dB
Gmwi = Gain of MW antenna in pertinent direction (dBi)
Ci = Channel discrimination of MW system in dB
Prmi = Power at MW receiver from mobiles associated with ith 
          base station
ptmi = e.i.r.p. transmitted from mobiles associated with ith 
          base station

[[Page 128]]

nmi = Number of mobiles associated with ith base station
Lmi = Path loss between MW and mobile transmitters in dB
Prpsi = Power at MW receiver from outdoor portables (s for 
          sidewalk)
ptpsi = e.i.r.p. transmitted from outdoor portables 
          associated with ith base station
npsi = Number of outdoor portables associated with ith base 
          station
Lpsi = Path loss between MW and outdoor portables in dB
Prpbi = Power at MW receiver from indoor portables (b for 
          building)
ptpbi = e.i.r.p. transmitted from indoor portables associated 
          with ith base station
npbi = number of indoor portables associated with ith base 
          station
Lpbi = Path loss in dB between MW and base station site 
          (using average building height divided by 2 as effective 
          antenna height)
Prpri = Power at MW receiver from rooftop portables (r for 
          rooftop)
ptpri = e.i.r.p. transmitted from rooftop portables 
          associated with ith base station
npri = Number of rooftop portables associated with ith base 
          station
Lpri = Path loss in dB between MW and base station site 
          (using average building height as effective antenna height)
BPi = Building penetration loss at street level in dB
BHi = Height gain for portables in buildings dB = 2.5 x (nf-
          1), where nf is number of floors

    Note: Where Ci varies from channel-to-channel, which 
often is the case, the summation process is more complex, requiring 
summation at a channel level first.

    Finally, the total PCS interference power at a given microwave 
receiver from all the base stations in a given frequency band is found 
by summing the contributions from the individual stations. Likewise, the 
total interference power at a given microwave receiver from all mobiles 
and portables operating in a given frequency band is found by summing 
the contributions from the mobiles and portables associated with each 
cell.
[GRAPHIC] [TIFF OMITTED] TR24JN94.017

    Base Stations. Interference from each base station to each microwave 
should normally be considered independently. A group of base stations 
having more or less (within 50 percent) the same 
height above average terrain, the same e.i.r.p., basically the same path 
to a microwave receiving site, and subtending an angle to that receiving 
site of less than 5 degrees, may be treated as a group, using the total 
power of the group and the average antenna height of the group to 
calculate path loss, L.
    Mobile Stations. The e.i.r.p. from mobile transmitters is weighted 
according to the number of base station channels expected to be devoted 
to mobile operation at any given time. The antenna height of mobiles 
used in calculating path loss, L, is assumed to be 2 meters.
    Portable Stations. The e.i.r.p. from the portable units associated 
with each base station is weighted according to the estimated portion of 
portables associated with that cell expected to be operated inside 
buildings at any given time and the portion which could be expected to 
be operating from elevated locations, such as balconies or building 
rooftops. For example, in the case of service intended for business use 
in an urban area, one might expect that perhaps 85 percent of the 
portables in use at any given time would be operating from within 
buildings and perhaps 5 percent might be operating from rooftops or 
balconies. The remaining 10 percent would be outside at street level.
    Calculation of an equivalent e.i.r.p. for cells in suburban areas 
will involve different weighting criteria.
    Urban Correction Factor. The urban correction factor (UC) depends on 
the height and density of buildings surrounding a base station. For the 
core area of large cities, it is assumed to be 35 dB. For medium size 
cities and fringe areas of large cities (4- to 6-story buildings with 
scattered taller buildings and lower buildings and open spaces) it is 
assumed to be 25 dB; for small cities and towns, 15 dB, and for suburban 
residential areas (one- and two-story, single family

[[Page 129]]

houses with scattered multiple-story apartment buildings, shopping 
centers and open areas), 10 dB.
    The unadjusted urban correction factor, UC, should not be applied to 
base station antenna heights that are greater than 50 percent of the 
average building height for a cell.
    Building Height and Building Penetration Factors. The building 
height correction, BH, is a function of the average building height 
within the nominal coverage area of the base station. It is used in 
conjunction with the building penetration loss, BP, to adjust the 
expected interference contribution from that portion of the portables 
transmitting from within buildings. The adjustment is given by:

BP = 20 dB in urban areas
BP = 10 dB in suburban areas
BH = 2.5 x (nf-1) dB

where nf is the average height (number of floors) of the buildings in 
the area.
    (Note that this formula implies a net gain when the average building 
height is greater than 8 floors). All buildings more than twice the 
average height should be considered individually. The contribution to BH 
from that portion of portables in the building above the average 
building height should be increased by a factor of 20Log(h) dB, where h 
is the height of the portables above the average building height in 
meters.
    Channel Discrimination Factor. A factor based on the interference 
selectivity of the microwave receiver.
    Propagation Model. The PCS to microwave path loss, L, is calculated 
using the Longley-Rice propagation model, Version 1.2.2., in the point-
to-point mode. The Longley-Rice [1] model was derived from NBS Technical 
Note 101 [2], and updated in 1982 by Hufford [3]. Version 1.2.2 
incorporated modifications described in a letter by Hufford [4] in 1985. 
Terrain elevations used as input to the model should be from the U.S. 
Geological Survey 3-second digitized terrain database.
    Special Situations. If a cell size is large compared to the distance 
between the cell and a microwave receiving site so that it subtends an 
angle greater than 5 degrees, the cell should be subdivided and 
calculations should be based on the expected distribution of mobiles and 
portables within each subdivision.
    If terrain elevations within a cell differ by more than a factor of 
two-to-one, the cell should be subdivided and microwave interference 
calculations should be based on the average terrain elevation for each 
subdivision.
    If a co-channel PCS base station lies within the main beam of a 
microwave antenna (5 degrees), there is no 
intervening terrain obstructions, and the power at the microwave 
receiver from that base station, assuming free space propagation, would 
be 3 dB or less below the interference threshold, interference will be 
assumed to exist unless the PCS licensee can demonstrate otherwise by 
specific path loss calculations based on terrain and building losses.
    If any part of a cell or cell subdivision lies within the main beam 
of a co-channel microwave antenna, there is no intervening terrain 
obstructions, and the accumulative power of 5 percent or less of the 
mobiles, assuming free space propagation would be 3 dB or less below the 
interference threshold, interference will be assumed to exist unless the 
PCS licensee can demonstrate otherwise by specific path loss 
calculations based on terrain and building losses.
    If a building within a cell or cell subdivision lies within the main 
beam of a co-channel microwave antenna, there is no intervening terrain 
obstructions, and the cumulative power of 5 percent or fewer of the 
portables, assuming free space propagation, would be 3 dB or less below 
the interference threshold, interference will be assumed to exist unless 
the PCS licensee can demonstrate otherwise by specific path loss 
calculations based on terrain and building losses.

    (3) Contain specific allegations of fact which, except for facts of 
which official notice may be taken, shall be supported by affidavit of a

    (iii) In cases of merger, acquisition, or other business combination 
of entities, where one or more of the entities are ineligible for the 
exception set forth in paragraph (a)(5)(i) of this section, the 
resulting entity will not be eligible pursuant to paragraph (a)(5)(i) of 
this section unless an eligible entity possesses de jure and de facto 
control over the resulting entity.

paragraphs (b)(1)(v) and (b)(1)(vi) of this section, ownership interests 
shall be calculated on a fully diluted basis; all agreements such as 
warrants, stock options and convertible debentures will generally be 
treated as if the rights thereunder already have been fully exercised, 
except that such agreements may not be used to appear to terminate or 
divest ownership interests before they actually do so, in order to 
comply with the nonattributable equity requirements in paragraphs 
(b)(1)(iii)(A) and (b)(1)(iv)(A) of this section.

hold interest in an applicant (or licensee) that are affiliates of each 
other or have an identify of interests identified in Sec.  
1.2110(c)(5)(iii) will be treated as though they were one person or 
entity and their ownership interests aggregated for purposes of 
determining an applicant's (or licensee's) compliance with the 
nonattributable equity requirements in paragraphs (b)(1)(iii)(A) and 
(b)(1)(iv)(A) of this section.

    Example 1 for paragraph (b)(1)(viii). ABC Corp. is owned by 
individuals, A, B, and C, each having an equal one-third voting interest 
in ABC Corp. A and B together, with two-thirds of the stock have the 
power to control ABC Corp. and have an identity of interest. If A & B 
invest in DE Corp., a broadband PCS applicant for block C, A and B's 
separate interests in DE Corp. must be aggregated because A and B are to 
be treated as one person.

[[Page 136]]

    Example 2 for paragraph (b)(1)(viii). ABC Corp. has subsidiary BC 
Corp., of which it holds a controlling 51 percent of the stock. If ABC 
Corp. and BC Corp., both invest in DE Corp., their separate interests in 
DE Corp. must be aggregated because ABC Corp. and BC Corp. are 
affiliates of each other.

    (2) The following provisions apply to licenses acquired pursuant to 
Sec.  24.839(a)(2) or (a)(3) on or after October 30, 2000. In addition 
to the eligibility requirements set forth at 24.709(a) and (b),

determining unjust enrichment payment obligations. See Sec.  1.2111 of 
this chapter.

Sec.  24.713  [Reserved]



Sec.  24.714  Partitioned licenses and disaggregated spectrum.

    (a) Eligibility. (1) Parties seeking approval for partitioning and 
disaggregation shall request an authorization for partial assignment of 
a license pursuant to Sec.  24.839.
    (2) Broadband PCS licensees in spectrum blocks A, B, D, and E and 
broadband PCS C and F block licenses not subject to the eligibility 
requirements of Sec.  24.709 may apply to partition their licensed 
geographic service area or disaggregate their licensed spectrum at any 
time following the grant of their licenses.
    (3) Broadband PCS licensees that acquired C or F block licenses in 
closed bidding subject to the eligibility requirements of Sec.  24.709 
may partition their licensed geographic service area or disaggregate 
their licensed spectrum at any time to an entity that meets the 
eligibility criteria set forth in Sec.  24.709 at the time the request 
for partial assignment of license is filed or to an entity that holds 
license(s) for frequency blocks C and F that met the eligibility 
criteria set forth in Sec.  24.709 at the time of receipt of such 
license(s). Partial assignment applications seeking partitioning or 
disaggregation of broadband PCS licenses in spectrum blocks C and F must 
include an attachment demonstrating compliance with this section.
    (b) Technical standards--(1) Partitioning. In the case of 
partitioning, applicants and licensees must file FCC Form 603 pursuant 
to Sec.  1.948 of this chapter and list the partitioned service area on 
a schedule to the application. The geographic coordinates must be 
specified in degrees, minutes, and seconds to the nearest second of 
latitude and longitude and must be based upon the 1983 North American 
Datum (NAD83).
    (2) Disaggregation. Spectrum may be disaggregated in any amount.
    (3) Combined partitioning and disaggregation. The Commission will 
consider requests for partial assignment of licenses that propose 
combinations of partitioning and disaggregation.
    (c) Installment payments--(1) Apportioning the balance on 
installment payment plans. When a winning bidder elects to pay for its 
license through an installment payment plan pursuant to Sec.  1.2110(g) 
of this chapter or Sec.  24.716, and partitions its licensed area or 
disaggregates spectrum to another party, the outstanding balance owed by 
the licensee on its installment payment plan (including accrued and 
unpaid interest) shall be apportioned between the licensee and 
partitionee or disaggregatee. Both parties will be responsible for 
paying their proportionate share of the outstanding balance to the U.S. 
Treasury. In the case of partitioning, the balance shall be apportioned 
based upon the ratio of the population of the partitioned area to the 
population of the entire original license area calculated based upon the 
most recent census data. In the case of disaggregation, the balance 
shall be apportioned based upon the ratio of the amount of spectrum 
disaggregated to the amount of spectrum allocated to the licensed area.
    (2) Parties not qualified for installment payment plans. (i) When a 
winning bidder elects to pay for its license through an installment 
payment plan, and partitions its license or disaggregates spectrum to 
another party that would not qualify for an installment payment plan or 
elects not to pay its share of the license through installment payments, 
the outstanding balance owed by the licensee (including accrued and 
unpaid interest shall be apportioned according to Sec.  24.714(c)(1)).
    (ii) The partitionee or disaggregatee shall, as a condition of the 
approval of the partial assignment application, pay its entire pro rata 
amount within 30 days of Public Notice conditionally granting the 
partial assignment application. Failure to meet this condition will 
result in a rescission of the grant of the partial assignment 
application.
    (iii) The licensee shall be permitted to continue to pay its pro 
rata share of

[[Page 139]]

the outstanding balance and shall receive new financing documents 
(promissory note, security agreement) with a revised payment obligation, 
based on the remaining amount of time on the original installment 
payment schedule. These financing documents will replace the licensee's 
existing financing documents, which shall be marked ``superseded'' and 
returned to the licensee upon receipt of the new financing documents. 
The original interest rate, established pursuant to Sec.  
1.2110(g)(3)(i) of this chapter at the time of the grant of the initial 
license in the market, shall continue to be applied to the licensee's 
portion of the remaining government obligation. The Commission will 
require, as a further condition to approval of the partial assignment 
application, that the licensee execute and return to the U.S. Treasury 
the new financing documents within 30 days of the Public Notice 
conditionally granting the partial assignment application. Failure to 
meet this condition will result in the automatic cancellation of the 
grant of the partial assignment application.
    (iv) A default on the licensee's payment obligation will only affect 
the licensee's portion of the market.
    (3) Parties qualified for installment payment plans. (i) Where both 
parties to a partitioning or disaggregation agreement qualify for 
installment payments, the partitionee or disaggregatee will be permitted 
to make installment payments on its portion of the remaining government 
obligations, as calculated according to Sec.  24.714(c)(1).
    (ii) Each party will be required, as a condition to approval of the 
partial assignment application, to execute separate financing documents 
(promissory note, security agreement) agreeing to pay their pro rata 
portion of the balance due (including accrued and unpaid interest) based 
upon the installment payment terms for which they qualify under the 
rules. The financing documents must be returned to the U.S. Treasury 
within thirty (30) days of the Public Notice conditionally granting the 
partial assignment application. Failure by either party to meet this 
condition will result in the automatic cancellation of the grant of the 
partial assignment application. The interest rate, established pursuant 
to Sec.  1.2110(g)(3)(i) of this chapter at the time of the grant of the 
initial license in the market, shall continue to be applied to both 
parties' portion of the balance due. Each party will receive a license 
for their portion of the partitioned market or disaggregated spectrum.
    (iii) A default on an obligation will only affect that portion of 
the market area held by the defaulting party.
    (iv) Partitionees and disaggregatees that qualify for installment 
payment plans may elect to pay some of their pro rata portion of the 
balance due in a lump sum payment to the U.S. Treasury and to pay the 
remaining portion of the balance due pursuant to an installment payment 
plan.
    (d) License term. The license term for a partitioned license area 
and for disaggregated spectrum shall be the remainder of the original 
licensee's license term as provided for in Sec.  24.15.

[68 FR 42999, July 21, 2003]



Sec.  24.720  Definitions.

24.709 through 24.717, unless otherwise specified in those sections.

that, together with its affiliates and persons or entities that hold 
interest in such entity and their affiliates, has average annual gross 
revenues that are not more than $40 million for the preceding three 
years.
    (2) A very small business is an entity that, together with its 
affiliates and persons or entities that hold interests in such entity 
and their affiliates, has average annual gross revenues that are not 
more than $15 million for the preceding three years.
    (c) Institutional Investor. An institutional investor is an 
insurance company, a bank holding stock in trust accounts through its 
trust department, or an investment company as defined in 15 U.S.C. 80a-
3(a), including within such definition any entity that would otherwise 
meet the definition of investment company under 15 U.S.C. 80a-3(a) but 
is excluded by the exemptions set forth in 15 U.S.C. 80a-3(b) and (c), 
without regard to whether such entity is an issuer of securities; 
provided that, if such investment company is owned, in whole or in part, 
by other entities, such investment company, such other entities and the 
affiliates of such other entities, taken as a whole, must be primarily 
engaged in the business of investing, reinvesting or trading in 
securities or in distributing or providing investment management 
services for securities.
    (d) Nonattributable Equity--(1) Nonattributable equity shall mean:
    (i) For corporations, voting stock or non-voting stock that includes 
no more than twenty-five percent of the total voting equity, including 
the right to vote such stock through a voting trust or other 
arrangement;
    (ii) For partnerships, joint ventures and other non-corporate 
entities, limited partnership interests and similar interests that do 
not afford the power to exercise control of the entity.
    (2) For purposes of assessing compliance with the equity limits in 
Sec.  24.709 (b)(1)(iii)(A) and (b)(1)(iv)(A), where such interests are 
not held directly in the applicant, the total equity held by a person or 
entity shall be determined by successive multiplication of the ownership 
percentages for each link in the vertical ownership chain.
    (e) Control Group. A control group is an entity, or a group of 
individuals or entities, that possesses de jure control and de facto 
control of an applicant or

[[Page 141]]

licensee, and as to which the applicant's or licensee's charters, 
bylaws, agreements and any other relevant documents (and amendments 
thereto) provide:
    (1) That the entity and/or its members own unconditionally at least 
50.1 percent of the total voting interests of a corporation;
    (2) That the entity and/or its members receive at least 50.1 percent

the amount of equity held in the corporation; and
    (4) That, for other types of businesses, the entity and/or its 
members have the right to receive dividends, profits and regular and 
liquidating distributions from the business in proportion to the amount 
of equity held in the business.

    Note to paragraph (e): Voting control does not always assure de 
facto control, such as for example, when the voting stock of the control 
group is widely dispersed (see e.g., Sec.  1.2110(c)(5)(ii)(C) of this 
chapter).

    (f) Publicly Traded Corporation with Widely Dispersed Voting Power. 
A publicly traded corporation with widely dispersed voting power is a 
business entity organized under the laws of the United States:
    (1) Whose shares, debt, or other ownership interests are traded on 
an organized securities exchange within the United States;
    (2) In which no person:
    (i) Owns more than 15 percent of the equity; or

voting securities, by contract or otherwise, the power to control the 
election of more than 15 percent of the members of the board of 
directors or other governing body of such publicly traded corporation; 
and
    (3) Over which no person other than the management and members of 
the board of directors or other governing body of such publicly traded 
corporation, in their capacities as such, has de facto control.
    (4) The term person shall be defined as in section 13(d) of the 
Securities and Exchange Act of 1934, as amended (15 U.S.C. 78(m)), and

indicia of control set forth in the definition of affiliate in Sec.  
1.2110(c)(5) of the Commission's rules.
    (g) Qualifying investor. (1) A qualifying investor is a person who 
is (or holds an interest in) a member of the applicant's (or licensee's) 
control group and whose gross revenues and total assets, when aggregated 
with those of all other attributable investors and affiliates, do not 
exceed the gross revenues and total assets limits specified in Sec.  
24.709(a), or, in the case of an applicant (or licensee) that is a small 
business, do not exceed the gross revenues limit specified in paragraph 
(b) of this section.
    (2) For purposes of assessing compliance with the minimum equity 
requirements of Sec.  24.709(b)(1)(v) and (b)(1)(vi), where such equity 
interests are not held directly in the applicant, interests held by 
qualifying investors shall be determined by successive multiplication of 
the ownership percentages for each link in the vertical ownership chain.
    (3) For purposes of Sec.  24.709(b)(1)(v)(A)(3) and 
(b)(1)(vi)(A)(3), a qualifying investor is a person who is (or holds an 
interest in) a member of the applicant's (or licensee's) control group 
and whose gross revenues and total assets do not exceed the gross 
revenues and total assets limits specified in Sec.  24.709(a).
    (h) Preexisting entity; Existing investor. A preexisting entity is 
an entity that was operating and earning revenues for at least two years 
prior to December 31, 1994. An existing investor is a person or entity 
that was an owner of record of a preexisting entity's equity as of 
November 10, 1994, and any person or entity acquiring de minimis equity 
holdings in a preexisting entity after that date.

    Note to paragraph (h): In applying the term existing investor to de 
minimis interests in preexisting entities obtained or increased after 
November 10, 1994, the Commission will

[[Page 142]]

scrutinize any significant restructuring of the preexisting entity that 
occurs after that date and will presume that any change of equity that 
is five percent or less of the preexisting entity's total equity is de 
minimis. The burden is on the applicant (or licensee) to demonstrate 
that changes that exceed five percent are not significant.

aggregate more PCS spectrum among them than a single entity is entitled 
to hold (See Sec. Sec.  20.6(e), 24.710, 24.204, 24.229(c) of this 
chapter) will be permitted to divest sufficient properties within 90 
days of the license grant to come into compliance with the spectrum 
aggregation limits as follows:
    (a) The broadband PCS applicant shall submit a signed statement with 
its long-form application stating that sufficient properties will be 
divested within 90 days of the license grant. If the licensee is 
otherwise qualified, the Commission will grant the applications subject 
to a condition that the licensee come into compliance with the PCS 
spectrum aggregation limits within 90 days of grant.
    (b) Within 90 days of license grant, the licensee must certify that 
the applicant and all parties to the application have come into 
compliance with the PCS spectrum aggregation limits. If the licensee 
fails to submit the certification within 90 days, the Commission will 
immediately cancel all broadband PCS licenses won by the applicant, 
impose the default penalty and, based on the facts presented, take any 
other action it may deem appropriate. Divestiture may be to an interim 
trustee if a buyer has not been secured in the required time frame, as 
long as the applicant has no interest in or control of the trustee, and 
the trustee may dispose of the property as it sees fit. In no event may 
the trustee retain the property for longer than six months from grant of 
license.

the distance on a given azimuth from an earth station sharing the same 
frequency band with terrestrial stations, or from a transmitting earth 
station sharing the same bidirectionally allocated frequency band with 
receiving earth stations, beyond which the level of permissible 
interference will not be exceeded and coordination is therefore not 
required. (RR)
    Direct Broadcast Satellite (DBS) Service. A radiocommunication 
service in which signals transmitted or retransmitted by Broadcasting-
Satellite Service space stations in the 12.2-12.7 GHz band are intended

of the antenna's main reflector. When non-reflector or non-circular-
aperture antennas are employed, the equivalent diameter is the diameter 
of a hypothetical circular-aperture antenna with the same aperture area 
as the actual antenna. For example, an elliptical aperture antenna with 
major axis a and minor axis b will have an equivalent diameter of [a x 
b]1/2. A rectangular aperture antenna with length l and width 
w will have an equivalent diameter of [4(l x w)/[pi]]1/2.
    Equivalent Power Flux Density (EPFD). The sum of the power flux 
densities produced at a geostationary-orbit receive earth or space 
station on the Earth's surface or in the geostationary orbit, as 
appropriate, by all the transmit stations within a non-geostationary-
orbit Fixed-Satellite Service system, taking into account the off-axis 
discrimination of a reference receiving antenna assumed to be pointing 
in its nominal direction. The equivalent power flux density, in dB(W/
m\2\) in the reference bandwidth, is calculated using the following 
formula:

Sec.  25.104  Preemption of local zoning of earth stations.

    (a) Any state or local zoning, land-use, building, or similar 
regulation that materially limits transmission or reception by satellite 
earth station antennas, or imposes more than minimal costs on users of 
such antennas, is preempted unless the promulgating authority can 
demonstrate that such regulation is reasonable, except that nonfederal 
regulation of radio frequency emissions is not preempted by this 
section. For purposes of this paragraph (a), reasonable means that the 
local regulation:
    (1) Has a clearly defined health, safety, or aesthetic objective 
that is stated in the text of the regulation itself; and
    (2) Furthers the stated health, safety or aesthetic objective 
without unnecessarily burdening the federal interests in ensuring access 
to satellite services and in promoting fair and effective competition 
among competing communications service providers.
    (b)(1) Any state or local zoning, land-use, building, or similar 
regulation that affects the installation, maintenance, or use of a 
satellite earth station antenna that is two meters or less in diameter 
and is located or proposed to be located in any area where commercial or 
industrial uses are generally permitted by non-federal land-use 
regulation shall be presumed unreasonable and is therefore preempted 
subject to paragraph (b)(2) of this section. No civil, criminal, 
administrative, or other legal action of any kind shall be taken to 
enforce any regulation covered by this presumption unless the 
promulgating authority has obtained a waiver from the Commission 
pursuant to paragraph (e) of this section, or a final declaration from 
the Commission or a court of competent jurisdiction

[[Page 152]]

that the presumption has been rebutted pursuant to paragraph (b)(2) of 
this section.
    (2) Any presumption arising from paragraph (b)(1) of this section 
may be rebutted upon a showing that the regulation in question:
    (i) Is necessary to accomplish a clearly defined health or safety 
objective that is stated in the text of the regulation itself;
    (ii) Is no more burdensome to satellite users than is necessary to 
achieve the health or safety objective; and
    (iii) Is specifically applicable on its face to antennas of the 
class described in paragraph (b)(1) of this section.
    (c) Any person aggrieved by the application or potential application 
of a state or local zoning or other regulation in violation of paragraph 
(a) of this section may, after exhausting all nonfederal administrative 
remedies, file a petition with the Commission requesting a declaration 
that the state or local regulation in question is preempted by this 
section. Nonfederal administrative remedies, which do not include 
judicial appeals of administrative determinations, shall be deemed 
exhausted when:
    (1) The petitioner's application for a permit or other authorization 
required by the state or local authority has been denied and any 
administrative appeal and variance procedure has been exhausted;
    (2) The petitioner's application for a permit or other authorization 
required by the state or local authority has been on file for ninety 
days without final action;
    (3) The petitioner has received a permit or other authorization 
required by the state or local authority that is conditioned upon the 
petitioner's expenditure of a sum of money, including costs required to 
screen, pole-mount, or otherwise specially install the antenna, greater 
than the aggregate purchase or total lease cost of the equipment as 
normally installed; or
    (4) A state or local authority has notified the petitioner of 
impending civil or criminal action in a court of law and there are no 
more nonfederal administrative steps to be taken.
    (d) Procedures regarding filing of petitions requesting declaratory 
rulings and other related pleadings will be set forth in subsequent 
Public Notices. All allegations of fact contained in petitions and 
related pleadings must be supported by affidavit of a person or persons 
with personal knowledge thereof.
    (e) Any state or local authority that wishes to maintain and enforce 
zoning or other regulations inconsistent with this section may apply to 
the Commission for a full or partial waiver of this section. Such 
waivers may be granted by the Commission in its sole discretion, upon a 
showing by the applicant that local concerns of a highly specialized or 
unusual nature create a necessity for regulation inconsistent with this 
section. No application for waiver shall be considered unless it 
specifically sets forth the particular regulation for which waiver is 
sought. Waivers granted in accordance with this section shall not apply 
to later-enacted or amended regulations by the local authority unless 
the Commission expressly orders otherwise.
    (f) A satellite earth station antenna that is designed to receive 
direct broadcast satellite service, including direct-to-home satellite 
services, that is one meter or less in diameter or is located in Alaska 
is covered by the regulations in Sec.  1.4000 of this chapter.

Sec.  25.105  Citizenship.

    The rules that establish the requirements and conditions for 
obtaining the Commission's prior approval of foreign ownership in common 
carrier licensees that would exceed the 20 percent limit in section 
310(b)(3) of the Communications Act (47 U.S.C. 310(b)(3)) and/or the 25

Sec.  25.111  Additional information, ITU filings, and ITU cost recovery.

    (a) The Commission may request from any party at any time additional 
information concerning any application, or any other submission or 
pleading regarding an application, filed under this part.
    (b) Applicants and licensees of radio stations governed by this part 
must provide the Commission with the information required for Advance 
Publication, Coordination, and Notification of frequency assignment 
filings, including due diligence information, pursuant to the Radio 
Regulations of the International Telecommunication Union. No protection 
from interference caused by radio stations authorized by other 
Administrations is guaranteed unless ITU procedures are timely completed 
or, with respect to individual Administrations, coordination agreements 
are successfully completed. A license for which such procedures have not 
been completed may be subject to additional terms and conditions 
required for coordination of the frequency assignments with other 
Administrations.
    (c) In the Direct Broadcast Satellite service, applicants and 
licensees shall also provide the Commission with all information it 
requires in order to modify the plans for the Broadcasting-Satellite 
Service (BSS) in Appendix 30 of the ITU Radio Regulations (RR) and 
associated feeder-link plans in Appendix 30A of the ITU RR, if the 
system has technical characteristics differing from those specified in 
the Appendix 30 BSS Plans, the Appendix 30A feederlink Plans, Annex 5 to 
Appendix 30, or Annex 3 to Appendix 30A. For such systems, no protection 
from interference caused by radio stations authorized by other 
Administrations is guaranteed until the agreement of all affected 
Administrations is obtained and the frequency assignment becomes a part 
of the appropriate Region 2 BSS and feeder-link Plans. Authorizations 
for which coordination is not completed and/or for which the necessary 
agreements under Appendices 30 and 30A have not been obtained may be 
subject to additional terms and conditions as required to effect 
coordination or obtain the agreement of other Administrations. 
Applicants and licensees shall also provide the Commission with the 
information required by Appendix 4 of the ITU RR for advance publication 
and notification or coordination of the frequencies to be used for 
tracking, telemetry and control functions of DBS systems.
    (d) The Commission will submit filings to the ITU on behalf of an 
applicant, licensee, or other requesting party only after the party has 
filed a signed declaration of unconditional acceptance of all consequent 
ITU cost-recovery responsibility. Applicants and licensees must file the 
declaration electronically in the application file in the International 
Communications Filing System (ICFS). In addition, applicants and 
licensees must reference the call sign and name of the satellite network 
in the declaration. All cost-recovery declarations must include the 
name(s), address(es), email address(es), and telephone number(s) of a 
contact person, or persons, responsible for cost recovery inquiries and 
ITU correspondence and filings. Supplements must be filed as necessary 
to apprise the Commission of changes in the contact information until 
the ITU cost-recovery responsibility is discharged. The applicant, 
licensee, or other party must remit payment of any resultant cost-
recovery fee to the ITU by the due date specified in the ITU invoice, 
unless an appeal is pending with the ITU that was filed prior to the due 
date. A license granted in reliance on such a commitment will be 
conditioned upon discharge of any such cost-recovery obligation. Where 
an applicant or licensee has an overdue ITU cost-recovery fee and does 
not have an appeal pending with the ITU, the Commission will dismiss any 
application associated with that satellite network.
    (e) The Commission will process and forward to the ITU up to five 
Advance Publication filings by an entity that are not accompanied by a 
complete space station license application or by an application pursuant 
to Sec.  25.110(b)(3)(i) or (b)(3)(ii). Such Advance Publication filing 
requests not contained in an application must be accompanied by a letter 
request and a signed ITU cost-recovery declaration pursuant to paragraph 
(d) of this section. A request for filing of Advance

[[Page 157]]

Publication information will be attributed to an entity in the same 
manner as a space station license application under the criteria set 
forth in Sec.  25.159(c).

    Note to paragraph (e): After June 30, 2016, the Commission will not 
forward Advance Publication information for satellite networks or 
systems subject to Article 9, Section II of the ITU Radio Regulations 
(incorporated by reference, see Sec.  25.108).

Sec.  25.112  Dismissal and return of applications.

    (a) An application will be unacceptable for filing and will be 
returned to the applicant with a brief statement identifying the 
omissions or discrepancies if:
    (1) The application is defective with respect to completeness of 
answers to questions, informational showings, internal inconsistencies, 
execution, or other matters of a formal character; or
    (2) The application does not substantially comply with the 
Commission's rules, regulations, specific requests for additional 
information, or other requirements.
    (3) The application requests authority to operate a space station in 
a frequency band that is not allocated internationally for such 
operations under the Radio Regulations of the International 
Telecommunication Union, unless the application is filed pursuant to 
Sec.  25.122 or Sec.  25.123.
    (4) The application is identical to a pending application that was 
timely filed pursuant to Sec.  25.157 or Sec.  25.158.
    (b) Applications for space station authority found defective under 
paragraph (a)(3) or (a)(4) of this section will not be considered. 
Applications for authority found defective under paragraphs (a)(1) or 
(a)(2) of this section may be accepted for filing if:
    (1) The application is accompanied by a request which sets forth the 
reasons in support of a waiver of (or an exception to), in whole or in 
part, any specific rule, regulation, or requirement with which the 
application is in conflict;
    (2) The Commission, upon its own motion, waives (or allows an 
exception to), in whole or in part, any rule, regulation or requirement.
    (c) The Commission will dismiss an application for failure to 
prosecute or for failure to respond substantially within a specified 
time period to official correspondence or requests for additional 
information. Dismissal will be without prejudice unless the application 
is mutually exclusive pursuant to Sec.  25.155, in which case it will be 
dismissed with prejudice.
    (d) An application will be dismissed without prejudice as a matter 
of right if the applicant requests its dismissal prior to final 
Commission action.

Sec.  25.113  Station construction, deployment approval, and operation
of spare satellites.

    (a) Construction permits are not required for earth stations. 
Construction of such stations may commence prior to grant of an earth 
station license at the applicant's own risk, subject to the requirements 
of Sec.  1.1312 and part 17 of this chapter concerning environmental 
processing and construction, marking, and lighting of antenna 
structures.
    (b) Construction permits are not required for Ancillary Terrestrial 
Component (ATC) stations. A party with licenses issued under this part 
for launch and operation of 1.5/1.6 GHz or 1.6/2.4 GHz GHz Mobile-
Satellite Service space stations and operation of associated ATC 
facilities may commence construction of ATC base stations at its own 
risk after commencing physical construction of the space stations, 
subject to the requirements of Sec.  1.1312 and part 17 of this chapter. 
Such an MSS/ATC licensee may also conduct equipment tests for the 
purpose of making adjustments and measurements necessary to ensure 
compliance with the terms of its ATC license, applicable rules in this 
part, and technical design requirements. Prior to commencing such 
construction and pre-operational testing, an MSS/ATC licensee must 
notify the Commission of the commencement of physical satellite 
construction

[[Page 158]]

and the licensee's intention to construct and test ATC facilities. This 
notification must be filed electronically in the appropriate file in the 
International Communications Filing System database. The notification 
must specify the frequencies the licensee proposes to use for pre-
operational testing and the name, address, and telephone number of a 
representative for the reporting and mitigation of any interference 
resulting from such testing. MSS/ATC licensees engaging in pre-
operational testing must comply with Sec. Sec.  5.83, 5.85(c), 5.111, 
and 5.117 of this chapter regarding experimental operations. An MSS/ATC 
licensee may not offer ATC service to the public for compensation during 
pre-operational testing.
    (c)-(e) [Reserved]
    (f) Construction permits are not required for U.S.-licensed space 
stations, except for stations that the applicant proposes to operate to 
disseminate program content to be received by the public at large, 
rather than only by subscribers. Construction of a station for which a 
construction permit is not required may commence, at the applicant's own 
risk, prior to grant of a license.
    (g) Except as set forth in paragraphs (h) and (i) of this section, 
approval for orbital deployment and a station license (i.e., operating 
authority) must be applied for and granted before a space station may be 
deployed and operated in orbit. Approval for orbital deployment may be 
requested in an application for a space station license. However, an 
application for authority to deploy and operate an on-ground spare 
satellite will be considered pursuant to the following procedures:
    (1) Applications for deployment and operation of an on-ground spare 
NGSO-like satellite will be considered pursuant to the procedures set 
forth in Sec.  25.157, except as provided in paragraph (g)(3) of this 
section.
    (2) Applications for deployment and operation of an on-ground spare 
GSO-like satellite will be considered pursuant to the procedures set 
forth in Sec.  25.158, except as provided in paragraph (g)(3) of this 
section.
    (3) Neither paragraph (g)(1) nor (g)(2) of this section will apply 
in cases where the space station to be deployed is determined to be an 
emergency replacement for a previously authorized space station that has 
been lost as a result of a launch failure or a catastrophic in-orbit 
failure.
    (h) An operator of NGSO space stations under a blanket license 
granted by the Commission, except for those granted pursuant to the 
application process in Sec.  25.122 or Sec.  25.123, need not apply for 
license modification to operate technically identical in-orbit spare 
satellites in an authorized orbit. However, the licensee must notify the 
Commission within 30 days of bringing an in-orbit spare into service and 
certify that its activation has not exceeded the number of space 
stations authorized to provide service and that the licensee has 
determined by measurement that the activated spare is operating within 
the terms of the license.
    (i) An operator of NGSO space stations under a blanket license 
granted by the Commission, except for those granted pursuant to the 
application process in Sec.  25.122 or Sec.  25.123, need not apply for 
license modification to deploy and operate technically identical 
replacement satellites in an authorized orbit within the term of the 
system authorization. However, the licensee must notify the Commission 
of the intended launch at least 30 days in advance and certify that its 
operation of the additional space station(s) will not increase the 
number of space stations providing service above the maximum number 
specified in the license.

Sec.  25.114  Applications for space station authorizations.

    (a)(1) A license application filed pursuant to Sec.  25.110(b)(2) 
for a GSO space station or NGSO space station or space-station 
constellation must comprise a comprehensive proposal and must be 
submitted on FCC Form 312,

[[Page 159]]

Main Form and Schedule S, with attached exhibits required by paragraph 
(d) of this section.
    (2) An application for blanket authority for an NGSO constellation 
of space stations that are not all technically identical must provide 
the information required by paragraphs (c) and (d) of this section for 
each type of station in the constellation.
    (3) For an application filed pursuant to the two-step procedure in 
Sec.  25.110(b)(3), the filing pursuant to Sec.  25.110(b)(3)(iii) must 
be submitted on FCC Form 312, Main Form and Schedule S, with attached 
exhibits as required by paragraph (d) of this section, and must 
constitute a comprehensive proposal.
    (b) Each application for a new or modified space station 
authorization must contain the formal waiver required by 47 U.S.C. 304.
    (c) The following information shall be filed on FCC Form 312, Main 
Form and Schedule S:
    (1) Name, address, and telephone number of the applicant;
    (2) Name, address, and telephone number of the person(s), including 
counsel, to whom inquiries or correspondence should be directed;
    (3) Type of authorization requested (e.g., launch authority, station 
license, modification of authorization);
    (4)(i) For each space station transmitting and receiving antenna 
beam (including telemetry and tracking beams but not command beams), 
specify channel center frequencies and bandwidths and polarization plan. 
For command beams, specify each of the center frequencies within a 5 MHz 
range or a range of 2 percent of the assigned bandwidth, whichever is 
smaller, and the polarization plan. If the space station can vary 
channel bandwidth in a particular frequency band with on-board 
processing, specify only the range of frequencies in that band over 
which the beam can operate and the polarization plan.
    (ii) Specify maximum EIRP and maximum EIRP density for each space 
station transmitting antenna beam. If the satellite uses shapeable 
antenna beams, as defined in Sec.  25.103, specify instead maximum 
possible EIRP and maximum possible EIRP density within each shapeable 
beam's proposed coverage area. Provide this information for each 
frequency band in which the transmitting antenna would operate. For 
bands below 15 GHz, specify EIRP density in dBW/4 kHz; for bands at and 
above 15 GHz, specify EIRP density in dBW/MHz. If the EIRP density 
varies over time, specify the maximum possible EIRP density.
    (iii)-(iv) [Reserved]
    (v) For each space station receiving beam other than command beams, 
specify the gain-to-temperature ratio at beam peak. For receiving beams 
fed into transponders, also specify the minimum and maximum saturation 
flux density at beam peak. If the satellite uses shapeable beams, 
specify the minimum and maximum gain-to-temperature ratio within each 
shapeable beam's proposed coverage area, and for shapeable receiving 
beams fed into transponders, specify the minimum and maximum saturation 
power flux density within the 0 dB relative antenna gain isoline. 
Provide this information for each frequency band in which the receiving 
beam can operate. For command beams, specify the beam peak flux density 
at the command threshold;
    (vi)(A) For space stations in geostationary orbit, specify predicted 
space station antenna gain contour(s) for each transmit and receive 
antenna beam, except for beams where the contour at 8 dB below peak 
falls entirely beyond the edge of the visible Earth. These contour(s) 
should be plotted on an area map at 2 dB intervals down to 10 dB below 
the peak gain and at 5 dB intervals between 10 dB and 20 dB below the 
peak gain. Applicants must present this information in a GIMS-readable 
format.
    (B) For space stations in non-geostationary orbits, specify for each 
unique orbital plane the predicted antenna gain contour(s) for each 
transmit and receive antenna beam for one space station if all space 
stations are identical in the constellation. If individual space 
stations in the constellation have different antenna beam 
configurations, specify the predicted antenna gain contours for each 
transmit and receive beam for each space station type and orbit or 
orbital plane requested. The contours should be plotted on an

[[Page 160]]

area map with the beam depicted on the surface of the earth with the 
space stations' peak antenna gain pointed at nadir to a latitude and 
longitude within the proposed service area. The contour(s) should be 
plotted at 2 dB intervals down to 10 dB below the peak gain and at 5 dB 
intervals between 10 dB and 20 dB below the peak gain. For 
intersatellite links, specify the peak antenna gain and 3 dB beamwidth.
    (C) For space stations with shapeable antenna beams, specify the 
contours, as defined in paragraph (c)(4)(vi)(A) or (B) of this section, 
for the transmitting beam configuration that results in the highest EIRP 
density for the beams listed in paragraph (c)(4)(ii) of this section and 
for the receiving beam configuration with the smallest gain-to-
temperature ratio and the highest required saturation power flux density 
for the beams listed in paragraph (c)(4)(v) of this section. If the 
shapeable beams are also steerable, include the contours that would 
result from moving the beam peak around the limit of the effective beam 
peak area and the 0 dB relative antenna gain isoline. The proposed 
maximum coverage area must be clearly specified.
    (D) For a space station with steerable beams that are not shapeable, 
specify the applicable contours, as defined in paragraph (c)(4)(vi)(A) 
or (c)(4)(vi)(B) of this section, with a description of a proposed 
coverage area for each steerable beam or provide the contour information 
described in paragraph (c)(4)(vi)(C) of this section for each steerable 
beam.
    (vii) For geostationary satellites with large numbers of identical 
fixed spot beams, other than DBS satellites, applicants may, as an 
alternative to submitting the information described in paragraph 
(c)(4)(vi) of this section with respect to these beams, provide the 
predicted antenna gain contours for one transmit and receive antenna 
beam, together with one of the following:
    (A) An area map showing all of the spot beams depicted on the 
surface of the Earth;

services and explanation of how uplink frequency bands would be 
connected to downlink frequency bands;
    (2)-(5) [Reserved]
    (6) Public interest considerations in support of grant;
    (7) Applicants for authorizations for space stations in the Fixed-
Satellite Service, including applicants proposing feeder links for space 
stations operating in the 17/24 GHz Broadcasting-Satellite Service, must 
also include the information specified in Sec.  25.140(a). Applicants 
for authorizations for space stations in the 17/24 GHz Broadcasting-
Satellite Service must also include the information specified in Sec.

all information necessary to comply with the policies and procedures set 
forth in Rules and Policies Pertaining to the Use of Radio Frequencies 
in a Land Mobile Satellite Service, 2 FCC Rcd 485 (1987) (Available at 
address in Sec.  0.445 of this chapter.);
    (9) Applications to license multiple space station systems in the 
non-voice, non-geostationary mobile-satellite service under blanket 
operating authority shall also provide all information specified in 
Sec.  25.142; and
    (10) An application for space station authorization in the 1.6/2.4 
GHz or 2 GHz Mobile-Satellite Service must include information required 
by Sec.  25.143(b);
    (11) Applications for space stations in the Direct Broadcast 
Satellite Service must include a clear and detailed statement of whether 
the space station is to be operated on a broadcast or non-broadcast 
basis;
    (12) The information required by Sec.  25.146, if the application is 
for an NGSO FSS system authorization within the 10.7-30 GHz band.
    (13) For satellite applications in the Direct Broadcast Satellite 
Service, if the proposed system's technical characteristics differ from 
those specified in the Appendix 30 BSS Plans, the Appendix 30A feeder 
link Plans, Annex 5 to Appendix 30 or Annex 3 to Appendix 30A of the ITU 
Radio Regulations, each applicant must provide:
    (i) The information requested in Appendix 4 of the ITU Radio 
Regulations. Further, applicants must provide sufficient technical 
showing that the proposed system could operate satisfactorily if all 
assignments in the BSS and feeder link Plans were implemented.
    (ii) Analyses of the proposed system with respect to the limits in 
Annex 1 to Appendices 30 and 30A of the ITU Radio Regulations.
    (14) A description of the design and operational strategies that 
will be used to mitigate orbital debris, including the following 
information:
    (i) A statement that the space station operator has assessed and 
limited the amount of debris released in a planned manner during normal 
operations, and has assessed and limited the probability of the space 
station becoming a source of debris by collisions with small debris or 
meteoroids that could cause loss of control and prevent post-mission 
disposal;
    (ii) A statement that the space station operator has assessed and 
limited the probability of accidental explosions during and after 
completion of mission operations. This statement must include a 
demonstration that debris generation will not result from the conversion 
of energy sources on board the spacecraft into energy that fragments the 
spacecraft. Energy sources include chemical, pressure, and kinetic 
energy. This demonstration should address whether stored energy will be 
removed at the spacecraft's end of life, by depleting residual fuel and 
leaving all fuel line valves open, venting any pressurized system, 
leaving all batteries in a permanent discharge state, and removing any 
remaining source of stored energy, or through other equivalent 
procedures specifically disclosed in the application;

[[Page 162]]

    (iii) A statement that the space station operator has assessed and 
limited the probability of the space station becoming a source of debris 
by collisions with large debris or other operational space stations. 
Where a space station will be launched into a low-Earth orbit that is 
identical, or very similar, to an orbit used by other space stations, 
the statement must include an analysis of the potential risk of 
collision and a description of what measures the space station operator 
plans to take to avoid in-orbit collisions. If the space station 
operator is relying on coordination with another system, the statement 
must indicate what steps have been taken to contact, and ascertain the 
likelihood of successful coordination of physical operations with, the 
other system. The statement must disclose the accuracy--if any--with 
which orbital parameters of non-geostationary satellite orbit space 
stations will be maintained, including apogee, perigee, inclination, and 
the right ascension of the ascending node(s). In the event that a system 
is not able to maintain orbital tolerances, i.e., it lacks a propulsion 
system for orbital maintenance, that fact should be included in the 
debris mitigation disclosure. Such systems must also indicate the 
anticipated evolution over time of the orbit of the proposed satellite 
or satellites. Where a space station requests the assignment of a 
geostationary-Earth orbit location, it must assess whether there are any 
known satellites located at, or reasonably expected to be located at, 
the requested orbital location, or assigned in the vicinity of that 
location, such that the station keeping volumes of the respective 
satellites might overlap. If so, the statement must include a statement 
as to the identities of those parties and the measures that will be 
taken to prevent collisions;
    (iv) A statement detailing the post-mission disposal plans for the 
space station at end of life, including the quantity of fuel--if any--
that will be reserved for post-mission disposal maneuvers. For 
geostationary-Earth orbit space stations, the statement must disclose 
the altitude selected for a post-mission disposal orbit and the 
calculations that are used in deriving the disposal altitude. The 
statement must also include a casualty risk assessment if planned post-
mission disposal involves atmospheric re-entry of the space station. In 
general, an assessment should include an estimate as to whether portions 
of the spacecraft will survive re-entry and reach the surface of the 
Earth, as well as an estimate of the resulting probability of human 
casualty. Applicants for space stations to be used only for commercial 
remote sensing may, in lieu of submitting detailed post-mission disposal 
plans to the Commission, certify that they have submitted such plans to 
the National Oceanic and Atmospheric Administration for review.
    (v) For non-U.S.-licensed space stations, the requirement to 
describe the design and operational strategies to minimize orbital 
debris risk can be satisfied by demonstrating that debris mitigation 
plans for the space station(s) for which U.S. market access is requested 
are subject to direct and effective regulatory oversight by the national 
licensing authority.
    (15) Each applicant for a space station license in the 17/24 GHz 
broadcasting-satellite service shall include the following information 
as an attachment to its application:
    (i) If the applicant proposes to operate in the 17.3-17.7 GHz 
frequency band, a demonstration that the proposed space station will 
comply with the power flux density limits in Sec.  25.208(w) unless the 
applicant provides a certification under paragraph (d)(15)(ii) of this 
section.
    (ii) In cases where the proposed space station will not comply with 
the power flux density limits set forth in Sec.  25.208(w) of this part, 
the applicant will be required to provide a certification that all 
potentially affected parties acknowledge and do not object to the use of 
the applicant's higher power flux densities. The affected parties with 
whom the applicant must coordinate are those GSO 17/24 GHz BSS satellite 
networks located up to 6[deg] away for excesses of 
up to 3 dB above the power flux-density levels specified in Sec.  
25.208(w) of this part, and up to 10[deg] away 
greater for excesses greater than 3 dB above those levels.

[[Page 163]]

    (iii) If the applicant proposes to provide international service in 
the 17.7-17.8 GHz frequency band, a certification that the proposed 
space station will comply with the power flux density limits in Sec.  
25.208(c).
    (iv) Any information required by Sec.  25.264(a)(6), 25.264(b)(4), 
or 25.264(d).
    (16) In addition to the requirements of paragraph (d)(15) of this 
section, each applicant for a license to operate a 17/24 GHz BSS space 
station that will be used to provide video programming directly to 
consumers in the United States, that will not meet the requirements of 
Sec.  25.225 of this part, must include as an attachment to its 
application a technical analysis demonstrating that providing video 
programming service to consumers in Alaska and Hawaii that is comparable 
to the video programming service provided to consumers in the 48 
contiguous United States (CONUS) is not feasible as a technical matter 
or that, while technically feasible, such service would require so many 
compromises in satellite design and operation as to make it economically 
unreasonable.
    (17) [Reserved]
    (18) For space stations in the Direct Broadcast Satellite service or 
the 17/24 GHz broadcasting-satellite service, maximum orbital 
eccentricity.

Management and Budget. For the convenience of the user, the revised text 
is set forth below:



Sec.  25.114  Applications for space station authorizations.

                                * * * * *

    (d) * * *
    (14) A description of the design and operational strategies that 
will be used to mitigate orbital debris, including the following 
information:
    (i) A statement that the space station operator has assessed and 
limited the amount of debris released in a planned manner during normal 
operations. Where applicable, this statement must include an orbital 
debris mitigation disclosure for any separate deployment devices, 
distinct from the space station launch vehicle, that may become a source 
of orbital debris;
    (ii) A statement indicating whether the space station operator has 
assessed and limited the probability that the space station(s) will 
become a source of debris by collision with small debris or meteoroids 
that would cause loss of control and prevent disposal. The statement 
must indicate whether this probability for an individual space station 
is 0.01 (1 in 100) or less, as calculated using the NASA Debris 
Assessment Software or a higher fidelity assessment tool;
    (iii) A statement that the space station operator has assessed and 
limited the probability, during and after completion of mission 
operations, of accidental explosions or of release of liquids that will 
persist in droplet form. This statement must include a demonstration 
that debris generation will not result from the conversion of energy 
sources on board the spacecraft into energy that fragments the 
spacecraft. Energy sources include chemical, pressure, and kinetic 
energy. This demonstration should address whether stored energy will be 
removed at the spacecraft's end of life, by depleting residual fuel and 
leaving all fuel line valves open, venting any pressurized system, 
leaving all batteries in a permanent discharge state, and removing any 
remaining source of stored energy, or through other equivalent 
procedures specifically disclosed in the application;
    (iv) A statement that the space station operator has assessed and 
limited the probability of the space station(s) becoming a source of 
debris by collisions with large debris or other operational space 
stations.
    (A) Where the application is for an NGSO space station or system, 
the following information must also be included:
    (1) A demonstration that the space station operator has assessed and 
limited the probability of collision between any space station of the 
system and other large objects (10 cm or larger in diameter) during the 
total orbital lifetime of the space station, including any de-orbit 
phases, to less than 0.001 (1 in 1,000). The probability shall be 
calculated using the NASA Debris Assessment Software or a higher 
fidelity assessment tool. The collision risk may be assumed zero for a 
space station during any period in which the space station will be 
maneuvered effectively to avoid colliding with large objects.
    (2) The statement must identify characteristics of the space 
station(s)' orbits that may present a collision risk, including any 
planned and/or operational space stations in

[[Page 164]]

those orbits, and indicate what steps, if any, have been taken to 
coordinate with the other spacecraft or system, or what other measures 
the operator plans to use to avoid collision.
    (3) If at any time during the space station(s)' mission or de-orbit 
phase the space station(s) will transit through the orbits used by any 
inhabitable spacecraft, including the International Space Station, the 
statement must describe the design and operational strategies, if any, 
that will be used to minimize the risk of collision and avoid posing any 
operational constraints to the inhabitable spacecraft.
    (4) The statement must disclose the accuracy, if any, with which 
orbital parameters will be maintained, including apogee, perigee, 
inclination, and the right ascension of the ascending node(s). In the 
event that a system is not able to maintain orbital tolerances, e.g., 
its propulsion system will not be used for orbital maintenance, that 
fact must be included in the debris mitigation disclosure. Such systems 
must also indicate the anticipated evolution over time of the orbit of 
the proposed satellite or satellites. All systems must describe the 
extent of satellite maneuverability, whether or not the space station 
design includes a propulsion system.
    (5) The space station operator must certify that upon receipt of a 
space situational awareness conjunction warning, the operator will 
review and take all possible steps to assess the collision risk, and 
will mitigate the collision risk if necessary. As appropriate, steps to 
assess and mitigate the collision risk should include, but are not 
limited to: Contacting the operator of any active spacecraft involved in 
such a warning; sharing ephemeris data and other appropriate operational 
information with any such operator; and modifying space station attitude 
and/or operations.
    (B) Where a space station requests the assignment of a geostationary 
orbit location, it must assess whether there are any known satellites 
located at, or reasonably expected to be located at, the requested 
orbital location, or assigned in the vicinity of that location, such 
that the station keeping volumes of the respective satellites might 
overlap or touch. If so, the statement must include a statement as to 
the identities of those satellites and the measures that will be taken 
to prevent collisions;
    (v) A statement addressing the trackability of the space station(s). 
Space station(s) operating in low-Earth orbit will be presumed trackable 
if each individual space station is 10 cm or larger in its smallest 
dimension, excluding deployable components. Where the application is for 
an NGSO space station or system, the statement shall also disclose the 
following:
    (A) How the operator plans to identify the space station(s) 
following deployment and whether space station tracking will be active 
or passive;
    (B) Whether, prior to deployment, the space station(s) will be 
registered with the 18th Space Control Squadron or successor entity; and
    (C) The extent to which the space station operator plans to share 
information regarding initial deployment, ephemeris, and/or planned 
maneuvers with the 18th Space Control Squadron or successor entity, 
other entities that engage in space situational awareness or space 
traffic management functions, and/or other operators.
    (vi) A statement disclosing planned proximity operations, if any, 
and addressing debris generation that will or may result from the 
proposed operations, including any planned release of debris, the risk 
of accidental explosions, the risk of accidental collision, and measures 
taken to mitigate those risks.
    (vii) A statement detailing the disposal plans for the space 
station, including the quantity of fuel--if any--that will be reserved 
for disposal maneuvers. In addition, the following specific provisions 
apply:
    (A) For geostationary orbit space stations, the statement must 
disclose the altitude selected for a disposal orbit and the calculations 
that are used in deriving the disposal altitude.
    (B) For space stations terminating operations in an orbit in or 
passing through the low-Earth orbit region below 2,000 km altitude, the 
statement must disclose whether the spacecraft will be disposed of 
through atmospheric re-entry, specifying if direct retrieval of the 
spacecraft will be used. The statement must also disclose the expected 
time in orbit for the space station following the completion of the 
mission.
    (C) For space stations not covered by either paragraph 
(d)(14)(vii)(A) or (B) of this section, the statement must indicate 
whether disposal will involve use of a storage orbit or long-term 
atmospheric re-entry and rationale for the selected disposal plan.
    (D) For all space stations under paragraph (d)(14)(vii) (B) or (C) 
of this section, the following additional specific provisions apply:
    (1) The statement must include a demonstration that the probability 
of success of the chosen disposal method will be 0.9 or greater for any 
individual space station. For space station systems consisting of 
multiple space stations, the demonstration should include additional 
information regarding efforts to achieve a higher probability of 
success, with a goal, for large systems, of a probability of success for 
any individual space station of 0.99 or better. For space stations under 
paragraph (d)(14)(vii)(B) of this section, successful disposal is 
defined as atmospheric re-entry of the spacecraft within 25 years or 
less following completion of the mission. For space stations under 
paragraph

[[Page 165]]

(d)(14)(vii)(C) of this section, successful disposal will be assessed on 
a case-by-case basis.
    (2) If planned disposal is by atmospheric re-entry, the statement 
must also include:
    (i) A disclosure indicating whether the atmospheric re-entry will be 
an uncontrolled re-entry or a controlled targeted reentry.
    (ii) An assessment as to whether portions of any individual 
spacecraft will survive atmospheric re-entry and impact the surface of 
the Earth with a kinetic energy in excess of 15 joules, and 
demonstration that the calculated casualty risk for an individual 
spacecraft using the NASA Debris Assessment Software or a higher 
fidelity assessment tool is less than 0.0001 (1 in 10,000).
    (E) Applicants for space stations to be used only for commercial 
remote sensing may, in lieu of submitting detailed post-mission disposal 
plans to the Commission, certify that they have submitted such plans to 
the National Oceanic and Atmospheric Administration for review.
    (viii) For non-U.S.-licensed space stations, the requirement to 
describe the design and operational strategies to minimize orbital 
debris risk can be satisfied by demonstrating that debris mitigation 
plans for the space station(s) for which U.S. market access is requested 
are subject to direct and effective regulatory oversight by the national 
licensing authority.

eligible for blanket or network licensing under another section of this 
part in the following circumstances:
    (i) The antennas would transmit in frequency bands shared with 
terrestrial services on a co-primary basis and the antennas would be 
sited within an area bounded by 1 second of latitude and 1 second of 
longitude.
    (ii) The antennas would transmit in frequency bands allocated to FSS 
on a primary basis and there is no co-primary allocation for terrestrial 
services, and the antennas would be sited within an area bounded by 10 
seconds of latitude and 10 seconds of longitude.
    (b) Receive-only earth stations. Except as provided in paragraphs 
(b)(1) and (8) of this section, applications for licenses for receive-
only earth stations must be submitted on FCC Form 312, Main Form and 
Schedule B, accompanied by any required exhibits and the information 
described in paragraphs (a)(5)(i) through (v) of this section. Such 
applications must be filed electronically through the International 
Communications Filing System (ICFS) in accordance with the applicable 
provisions of part 1, subpart Y, of this chapter.
    (1) Receive-only earth stations in the FSS that operate with U.S.-
licensed space stations, or with non-U.S.-licensed space stations that 
have been duly approved for U.S. market access, may be registered with 
the Commission in order to protect them from interference from 
terrestrial microwave stations in bands shared co-equally with the Fixed 
Service in accordance with the procedures of Sec. Sec.  25.203 and 
25.251, subject to the stricture in Sec.  25.209(c).
    (2) Licensing or registration of receive-only earth stations with 
the Commission confers no authority to receive and use signals or 
programming received from satellites. See Section 705 of the 
Communications Act. 47 U.S.C. 605.
    (3) Applications for registration must be accompanied by the 
coordination exhibit required by Sec.  25.203 and any other required 
exhibits.
    (4) Complete applications for registration will be placed on public 
notice for 30 days and automatically granted if no objection is 
submitted to the Commission and served on the applicant. Additional 
pleadings are authorized in accordance with Sec.  1.45 of this chapter.
    (5) The registration of a receive-only earth station results in the 
listing of an authorized frequency band at the location specified in the 
registration. Interference protection levels are those agreed to during 
coordination.

[[Page 168]]

    (6) Reception of signals or programming from non-U.S. satellites may 
be subject to restrictions as a result of international agreements or 
treaties. The Commission will maintain public information on the status 
of any such agreements.
    (7) Registration term: Registrations for receive-only earth stations 
governed by this section will be issued for a period of 15 years from 
the date on which the application was filed. Applications for renewals 
of registrations must be submitted on FCC Form 312R (Application for 
Renewal of Radio Station License in Specified Services) no earlier than 
90 days and no later than 30 days before the expiration date of the 
registration.
    (8) Applications for modification of license or registration of 
receive-only earth stations must be made in conformance with Sec. Sec.  
25.117 and 25.118. In addition, registrants are required to notify the 
Commission when a receive-only earth station is no longer operational or 
when it has not been used to provide any service during any 6-month 
period.
    (9)(i) Except as set forth in paragraph (b)(9)(ii) of this section, 
receive-only earth stations operating with non-U.S. licensed space 
stations must file an FCC Form 312 requesting a license or modification 
to operate such station.
    (ii) Operators of receive-only earth stations need not apply for a 
license to receive transmissions from non-U.S.-licensed space stations 
that have been duly approved for U.S. market access, provided the space 
station operator and earth station operator comply with all applicable 
rules in this chapter and with applicable conditions in the Permitted 
Space Station List or market-access grant.
    (c)(1) GSO FSS earth stations in 10.7-12.2 GHz or 14-14.5 GHz. A 
blanket license application for operation in the 10.7-12.2 GHz or 14-
14.5 GHz bands may be filed on FCC Form 312 or Form 312EZ, with a 
Schedule B for each large (5 meters or larger) hub station antenna and 
each representative type of small antenna (less than 5 meters) operating 
within the network; however, blanket licensing in the 10.7-11.7 GHz band 
is on an unprotected basis with respect to the fixed service.
    (i) Applications to license networks of earth stations operating in 
the 11.7-12.2 GHz and 14.0-14.5 GHz bands under blanket operating 
authority that meet the requirements of Sec.  25.212(c) or Sec.  
25.218(e) or (f) will be routinely processed.
    (ii) Applications to license networks of earth stations operating in 
the 11.7-12.2 GHz and 14.0-14.5 GHz bands under blanket operating 
authority that do not meet the requirements of Sec.  25.212(c) or Sec.  
25.218(e) or (f) must comply with the requirements in Sec.  25.220 and 
must be filed on FCC Form 312 with a Schedule B for each large (5 meters 
or larger) hub station antenna and each representative type of small 
antenna (less than 5 meters) operating within the network.
    (2) Networks of earth stations operating in the 3700-4200 MHz and 
5925-6425 MHz bands. Applications to license networks of earth stations 
operating in the 3700-4200 MHz and 5925-6425 MHz bands must be filed 
electronically on FCC Form 312, Main Form and Schedule B. Applications 
will be routinely processed provided that frequency coordination has 
been satisfactorily completed and that the proposed earth stations 
comply with the applicable provisions in Sec.  25.211(d) or Sec.  
25.212(d). Alternatively, applicants that have satisfactorily completed 
frequency coordination may be routinely processed if the proposed earth 
stations comply with the applicable off-axis EIRP density limits in 
Sec.  25.218(c) or (d).
    (i) For earth station antennas operating with power levels not 
consistent with the applicable provisions in Sec.  25.211(d) or Sec.  
25.212(d), or with EIRP density levels not consistent with those 
specified in Sec.  25.218(c) or (d), the applicant must file an initial 
lead application providing a detailed overview of the complete network. 
Such lead applications must fully identify the scope and nature of the 
service to be provided, as well as the complete technical details of 
each representative type of antenna that will operate within the 
network. Such lead applications for a single system must identify:
    (A) No more than three geostationary satellites to be accessed;
    (B) The amount of frequency bandwidth sought, up to a maximum of 20

[[Page 169]]

MHz of spectrum in each direction at each of the satellites (The same 20 
MHz of uplink and 20 MHz of downlink spectrum at each satellite would be 
accessible by all earth stations in the system. The 20 MHz of uplink and 
20 MHz of downlink spectrum need not be the same at each satellite 
location);
    (C) The maximum number of earth station sites;
    (ii) Following the issuance of a license for the lead application, 
the licensee shall notify the Commission of the complete technical 
parameters of each individual earth station site before that site is 
bought into operation under the lead authorization. Full frequency 
coordination of each individual site (e.g., for each satellite and the 
spectrum associated therewith) shall be completed prior to filing 
Commission notification. The coordination must be conducted in 
accordance with Sec.  25.203. Such notification shall be done by 
electronic filing and shall be consistent with the technical parameters 
of Schedule B of FCC Form 312.
    (iii) Following successful coordination of such an earth station, if 
the earth station operator does not file a lead application or a 
Schedule B within six months after it successfully completes 
coordination, it will be assumed that such frequency use is no longer 
desired, unless a second notification has been received within ten days 
prior to the end of the six month period. Such renewal notifications 
must be sent to all parties concerned. If the lead application or 
Schedule B, or renewal notification, is not timely received, the 
coordination will lapse and the licensee must re-coordinate the relevant 
earth stations if it still wishes to bring them into operation.
    (iv) Operation of each individual site may commence immediately 
after the public notice is released that identifies the notification 
sent to the Commission and if the requirements of paragraph (c)(2)(vi) 
of this section are met. Continuance of operation of each station for 
the duration of the lead license term shall be dependent upon successful 
completion of the normal public notice process. If any objections are 
received to the new station prior to the end of the 30 day comment 
period of the Public Notice, the licensee shall immediately cease 
operation of those particular stations until the coordination dispute is 
resolved and the licensee informs the Commission of the resolution. If 
the requirements of paragraph (c)(2)(vi) of this section are not met, 
operation may not commence until the Commission issues the public notice 
acting on the terminal authorization.
    (v) Each licensee shall annually provide the Commission an updated 
list of all operational earth stations in its system. The annual list 
shall also include a list of all earth stations deactivated during the 
year and identification of the satellites providing service to the 
network as of the date of the report.
    (vi) Conditional authorization. (A) An applicant for a new radio 
station or modification of an existing station authorized under 
paragraph (c)(2)(i) of this section in the 3700-4200; or 5925-6425 MHz 
bands may operate the proposed station during the pendency of its 
application after the release of the public notice accepting the 
notification for filing that complies with paragraph (c)(2)(ii) of this 
section. The applicant, however, must first certify that the following 
conditions are satisfied:
    (1) The frequency coordination procedures of Sec.  25.203 have been 
successfully completed;
    (2) The antenna structure has been previously studied by the Federal 
Aviation Administration and determined to pose no hazard to aviation 
safety as required by subpart B of part 17 of this chapter; or the 
antenna or tower structure does not exceed 6.1 meters above ground level 
or above an existing man-made structure (other than an antenna 
structure), if the antenna or tower has not been previously studied by 
the Federal Aviation Administration and cleared by the FCC;
    (3) The grant of the application(s) does not require a waiver of the 
Commission's rules (with the exception of a request for waiver 
pertaining to fees);
    (4) The applicant has determined that the facility(ies) will not 
significantly affect the environment as defined in Sec.  1.1307 of this 
chapter after complying

[[Page 170]]

with any applicable environmental notification procedures specified in 
Sec.  17.4(c) of this chapter.
    (5) The station site does not lie within 56.3 kilometers of any 
international border or within a radio ``Quiet Zone'' identified in 
Sec.  1.924 of this chapter; and
    (6) The filed application is consistent with the proposal that was 
coordinated pursuant to Sec.  25.251.
    (B) Conditional authority ceases immediately if the Schedule B is 
returned by the Commission because it is not accepted for filing.
    (C) A conditional authorization pursuant to paragraphs (c)(2)(vi)(A) 
and (c)(2)(vi)(B) of this section is evidenced by retaining a copy of 
the Schedule B notification with the station records. Conditional 
authorization does not prejudice any action the Commission may take on 
the subject application(s) or the Schedule B notifications.
    (D) Conditional authority is accepted with the express understanding 
that such authority may be modified or cancelled by the Commission at 
any time without hearing if, in the Commission's discretion, the need 
for such action arises. An applicant operating pursuant to this 
conditional authority assumes all risks associated with such operation, 
the termination or modification of the conditional authority, or the 
subsequent dismissal or denial of its application(s).
    (E) The copy of the Schedule B notification form must be posted at 
each station operating pursuant to this section.
    (vii) Period of construction. Construction of each earth station 
must be completed and the station must be brought into regular operation

Commission no later than 30 days after the transfer or assignment is 
completed. The notification must be filed on FCC Form 312, Main Form and 
Schedule A and must contain a certification that the transfer of control 
or assignment was pro forma and that, together with all previous pro 
forma transactions, it did not result in a change in the actual 
controlling party.
    (i) Pro forma transactions not involving a telecommunications 
carrier. A complete application for Commission approval of a non-
substantial (pro forma) transfer of control or assignment of license not 
involving a telecommunications carrier, as defined in 47 U.S.C. 153(51), 
will be deemed granted one business day after filing, provided that:
    (1) Approval does not require a waiver of, or a declaratory ruling 
pertaining to, any applicable Commission rule; and
    (2) The application includes a certification that the proposed 
transfer of control or assignment is pro forma and that, together with 
all previous pro forma transactions, it would not result in a change in 
the actual controlling party.
    (j) Receive-only earth station registrations. You do not need prior 
Commission approval for a transfer of control or assignment of a 
receive-only earth station registration. For all such transactions other 
than non-substantial (pro forma) transfers of control, the transferee or 
assignee must file a notification with the Commission on FCC Form 312, 
Main Form and Schedule A no later than 30 days after the transfer

Sec.  25.120  Application for special temporary authorization.

    (a) In circumstances requiring immediate or temporary use of 
facilities, request may be made for special temporary authority to 
install and/or operate new or modified equipment. The request must 
contain the full particulars of the proposed operation including all 
facts sufficient to justify the temporary authority sought and the 
public interest therein. No request for temporary authority will be 
considered unless it is received by the Commission at least 3 working 
days prior to the date of proposed construction or operation or, where 
an extension is sought, the expiration date of the existing temporary 
authorization. A request received within less than 3 working days may be 
accepted only upon due showing of extraordinary reasons for the delay in 
submitting the request which could not have been earlier foreseen by the 
applicant. A copy of the request for special temporary authority also 
shall be forwarded to the Commission's Columbia Operations Center, 9200 
Farm House Lane, Columbia, MD 21046-1609.
    (b)(1) The Commission may grant a temporary authorization only upon 
a finding that there are extraordinary circumstances requiring temporary 
operations in the public interest and that delay in the institution of 
these temporary operations would seriously prejudice the public 
interest. Convenience to the applicant, such as marketing considerations 
or meeting scheduled customer in-service dates, will not be deemed 
sufficient for this purpose.
    (2) The Commission may grant a temporary authorization for a period 
not to exceed 180 days, with additional periods not exceeding 180 days, 
if the Commission has placed the special temporary authority (STA) 
request on public notice.
    (3) The Commission may grant a temporary authorization for a period 
not to exceed 60 days, if the STA request has not been placed on public 
notice, and the applicant plans to file a request for regular authority 
for the service.
    (4) The Commission may grant a temporary authorization for a period 
not to exceed 30 days, if the STA request has not been placed on public 
notice, and an application for regular authority is not contemplated.
    (c) Each application proposing construction of one or more earth 
station antennas or alteration of the overall height of one or more 
existing earth station antenna structures, where FAA notification prior 
to such construction or alteration is required by part 17 of this 
chapter, must include the FCC Antenna Structure Registration Number(s) 
for the affected satellite earth station antenna(s). If no such number 
has been assigned at the time the application(s) is filed, the applicant 
must state in the application whether the satellite earth station 
antenna owner has notified the FAA of the proposed construction or 
alteration and applied to the FCC for an Antenna Structure Registration 
Number in accordance with part 17 of this chapter. Applications 
proposing construction of one or more earth station antennas or 
alteration of the overall height of one or more existing earth station 
antennas, where FAA notification prior to such construction or 
alteration is not required by part 17 of this chapter, must indicate 
such and, unless the satellite earth station antenna is 6.10 meters or 
less above ground level (AGL), must contain a statement explaining why 
FAA notification is not required.

Sec.  25.132  Verification of earth station antenna performance.

    (a)(1) Except as provided in paragraph (a)(2) of this section, 
applications for transmitting earth stations in the FSS, including 
feeder-link stations, must include a certification that the applicant 
has reviewed the results of a series of radiation pattern tests 
performed by the antenna manufacturer on representative equipment in 
representative configurations, and the test results demonstrate that the 
equipment meets relevant off-axis gain standards in Sec.  25.209, 
measured in accordance with paragraph (b)(1) of this section. Applicants 
and licensees must be prepared to submit the radiation pattern 
measurements to the Commission on request.
    (2) Applicants that specify off-axis EIRP density pursuant to Sec.  
25.115(g)(1) are exempt from the certification requirement in paragraph 
(a)(1) of this section.
    (b)(1) For purposes of paragraph (a)(1) of this section and Sec.  
25.115(g)(1), the following measurements on a production antenna 
performed on calibrated antenna range must be made at the top and bottom 
of each frequency band assigned for uplink transmission:
    (i)(A) Co-polarized gain in the azimuth plane must be measured 
across a range extending to 180[deg] on each side of the main-lobe axis, 
and the measurements must be represented in two plots: one across the 
entire angular range of 180[deg] from the main-
lobe axis and the other across 10[deg] from the 
main-lobe axis.
    (B) Co-polarized gain must be measured from 0[deg] to 30[deg] from 
beam peak in the elevation plane.
    (ii) Cross-polarization gain must be measured across a range of plus 
and minus 7[deg] from beam peak in the azimuth and elevation planes.
    (iii) Main beam gain.
    (iv) For antennas with asymmetric apertures or beams, where the 
minor axis of the antenna beam (major axis of the antenna aperture) will 
not always be aligned parallel to the plane tangent to the GSO arc, the 
measurements in

[[Page 188]]

paragraphs (b)(1)(i) through (iii) of this section must be made over the 
angular ranges specified in paragraphs (b)(1)(i)(A) and (B) of this 
section in two orthogonal planes, with the antenna oriented at the 
maximum skew angle at which it will operate.
    (2) The relevant envelope specified in Sec.  25.209 must be 
superimposed on each measured pattern.
    (c) The tests specified in paragraph (b) of this section are 
normally performed at the manufacturer's facility; but for those 
antennas that are very large and only assembled on-site, on-site 
measurements may be used for product qualification data. If on-site data 
is to be used for qualification, the test frequencies and number of 
patterns should follow, where possible, the recommendations in paragraph 
(b) of this section, and the test data is to be submitted in the same 
manner as described in paragraph (a) of this section.
    (d) For each new or modified transmitting antenna over 3 meters in 
diameter, the following on-site verification measurements must be 
completed at one frequency on an available transponder in each frequency 
band of interest and submitted to the Commission.
    (1) Co-polarized patterns in the elevation plane, plus and minus 7 
degrees, in the transmit band.
    (2) Co-polarized patterns in the azimuth and elevation planes, plus 
and minus 7 degrees, in the receive band.
    (3) System cross-polarization discrimination on-axis. The FCC 
envelope specified in Sec.  25.209 shall be superimposed on each 
pattern. The transmit patterns are to be measured with the aid of a co-
operating earth station in coordination with the satellite system 
control center under the provisions of Sec.  25.272.
    (e) Certification that the tests required by paragraph (c) of this 
section have been satisfactorily performed shall be provided to the 
Commission in notification that construction of the facilities has been 
completed as required by Sec.  25.133.
    (f) Antennas less than 3 meters in diameter and antennas on simple 
(manual) drive mounts that are operated at a fixed site are exempt from 
the requirements of paragraphs (c) and (d) of this section provided that 
a detailed technical showing is made that confirms proper installation, 
pointing procedures, and polarization alignment and manufacturing 
quality control. These showing must also include a plan for periodic 
testing and field installation procedures and precautions.
    (g) Records of the results of the tests required by this section 
must be maintained at the antenna site or the earth station operator's 
control center and be available for inspection.

seeking a license from a country that is a member of the World Trade 
Organization for services covered under the World Trade Organization 
Basic Telecommunications Agreement.
    (b) Any request pursuant to paragraph (a) of this section must be 
filed electronically through the International Communications Filing 
System and must include an exhibit providing legal and technical 
information for the non-U.S.-licensed space station of the kind that 
Sec.  25.114, Sec.  25.122, or Sec.  25.123 would require in a license 
application for that space station, including but not limited to, 
information required to complete Schedule S. An applicant may satisfy 
this requirement by cross-referencing a pending application containing 
the requisite information or by citing a prior grant of authority to 
communicate via the space station in question in the same frequency 
bands to provide the same type of service.
    (c) A non-U.S.-licensed NGSO-like satellite system seeking to serve 
the

[[Page 194]]

United States can be considered contemporaneously with other U.S. NGSO-
like satellite systems pursuant to Sec.  25.157 and considered before 
later-filed applications of other U.S. satellite system operators, and a 
non-U.S.-licensed GSO-like satellite system seeking to serve the United 
States can have its request placed in a queue pursuant to Sec.  25.158 
and considered before later-filed applications of other U.S. satellite 
system operators, if the non-U.S.-licensed satellite system:
    (1) Is in orbit and operating;
    (2) Has a license from another administration; or
    (3) Has been submitted for coordination to the International 
Telecommunication Union.
    (d) Earth station applicants requesting authority to communicate 
with a non-U.S.-licensed space station and entities filing a petition 
for declaratory ruling to access the United States market must 
demonstrate that the non-U.S.-licensed space station has complied with 
all applicable Commission requirements for non-U.S.-licensed systems to 
operate in the United States, including but not limited to the 
following:
    (1) Milestones;
    (2) Reporting requirements;
    (3) Any other applicable service rules;
    (4) The surety bond requirement in Sec.  25.165, for non-U.S.-
licensed space stations that are not in orbit and operating.

operation that have one market access request on file with the 
Commission in a particular frequency band, or one granted market access 
request for an unbuilt NGSO-like system in a particular frequency band, 
other than those filed or granted under the procedures in Sec.  25.122 
or Sec.  25.123, will not be permitted to request access to the U.S. 
market through another NGSO-like system in that frequency band. This 
paragraph (d)(5) shall not apply to recipients of U.S. market access 
applying under Sec.  25.122 or Sec.  25.123.
    (e) An entity requesting access to the United States market through 
a non-U.S.-licensed space station pursuant to a petition for declaratory 
ruling may amend its request by submitting an additional petition for 
declaratory ruling. Such additional petitions will be treated on the 
same basis as amendments filed by U.S. space station applicants for 
purposes of determining the order in which the petitions will be 
considered relative to pending applications and petitions.
    (f) A non-U.S.-licensed space station operator that has been granted 
access to the United States market pursuant to a declaratory ruling may 
modify its U.S. operations under the procedures set forth in Sec. Sec.  
25.117(d) and (h) and 25.118(e).
    (g) A non-U.S.-licensed satellite operator that acquires control of 
a non-U.S.-licensed space station that has been permitted to serve the 
United States must notify the Commission within 30 days after 
consummation of the transaction so that the Commission can afford 
interested parties an opportunity to comment on whether the transaction 
affected any of the considerations we made when we allowed the satellite 
operator to enter the U.S. market. A non-U.S.-licensed satellite that 
has been transferred to new owners may continue to provide service in 
the United States unless and until the Commission determines otherwise. 
If the transferee or assignee is not licensed by, or seeking a license 
from, a country that is a member of the World Trade Organization for 
services covered under the World Trade Organization Basic 
Telecommunications Agreement, the non-U.S.-licensed satellite operator 
will be required to make the showing described in paragraph (a) of this 
section.

that they will not cause unacceptable interference to any non-voice, 
non-geostationary mobile-satellite service system authorized to 
construct or operate.
    (2) Applicants for a non-voice, non-geostationary Mobile-Satellite 
Service space station license must identify the power flux density 
produced at the Earth's surface by each space station of their system in 
the 137-138 MHz and 400.15-401 MHz bands, to allow determination of 
whether coordination with terrestrial services is required under any 
applicable footnote to the Table of Frequency Allocations in Sec.  2.106 
of this chapter. In addition, applicants must identify the measures they 
would employ to protect the radio astronomy service in the 150.05-153 
MHz and 406.1-410 MHz bands from harmful interference from unwanted 
emissions.
    (3) Emission limitations. (i) Applicants in the non-voice, non-
geostationary mobile-satellite service shall show that their space 
stations will not exceed the emission limitations of Sec.  25.202(f) 
(1), (2) and (3), as calculated for a fixed point on the Earth's surface 
in the plane of the space station's orbit, considering the worst-case 
frequency tolerance of all frequency determining components, and maximum 
positive and negative Doppler shift of both the uplink and downlink 
signals, taking into account the system design.

agencies of the Federal government. The Federal use of frequencies in 
the non-voice, non-geostationary mobile-satellite service frequency 
bands is under the regulatory jurisdiction of the National 
Telecommunications and Information Administration (NTIA).
    (ii) The Commission will use its existing procedures for liaison 
with NTIA to reach agreement with respect to achieving compatible 
operations between Federal Government users under the jurisdiction of 
NTIA and non-voice, non-geostationary Mobile-Satellite Service systems 
(including user transceivers subject to blanket licensing under Sec.  
25.115(d)) through the frequency assignment and coordination practices 
established by NTIA and the Interdepartment Radio Advisory Committee 
(IRAC). In order to facilitate such frequency assignment and 
coordination, applicants shall provide the Commission with sufficient 
information to evaluate electromagnetic compatibility with the Federal 
government use of the spectrum, and any additional information requested 
by the Commission. As part of the coordination process, applicants shall 
show that they will not cause unacceptable interference to authorized 
Federal government users, based upon existing system information 
provided by the Government. The frequency assignment and coordination of 
the satellite system with Federal Government users shall be completed 
prior to grant of authorization.
    (iii) The Commission shall also coordinate with NTIA/IRAC with 
regard to the frequencies to be shared by those earth stations of non-
voice, non-geostationary mobile-satellite service systems that are not 
subject to blanket licensing under Sec.  25.115(d), and authorized 
Federal government stations in the fixed and mobile services, through 
the exchange of appropriate systems information.
    (3) Coordination among non-voice, non-geostationary mobile-satellite 
service systems. Applicants for authority to establish non-voice, non-
geostationary mobile-satellite service systems are encouraged to 
coordinate their proposed frequency usage with existing permittees and 
licensees in the non-voice, non-geostationary mobile-satellite service 
whose facilities could be affected by the new proposal in terms of 
frequency interference or restricted system capacity. All affected 
applicants, permittees, and licensees shall, at the direction of the 
Commission, cooperate fully and make every reasonable effort to resolve 
technical problems and conflicts that may inhibit effective and 
efficient use of the radio spectrum; however, the permittee or licensee 
being coordinated with is not obligated to suggest changes or re-
engineer an applicant's proposal in cases involving conflicts.
    (4) Safety and distress communications. Stations operating in the 
non-voice, non-geostationary mobile-satellite service that are used to 
comply with any statutory or regulatory equipment carriage requirements 
may also be subject to the provisions of sections 321(b) and 359 of the 
Communications Act of 1934, as amended. Licensees are advised that these 
provisions give priority to radio communications or signals relating to 
ships in distress and prohibit a charge for the transmission of maritime 
distress calls and related traffic.

operation provided it is able to demonstrate that the use of a non-
forward-band mode of operation would produce no greater potential 
interference than that produced as a result of implementing the rules of 
this section. A 1.6/2.4 GHz band licensee is permitted to apply for ATC 
authorization on a non-forward-band mode of operation where the 
equipment deployed will meet the requirements of paragraph (c)(4) of 
this section.

    (2) ATC operations shall be limited to certain frequencies:
    (i) [Reserved]
    (ii) In the 1626.5-1660.5 MHz/1525-1559 MHz bands (L-band), ATC 
operations are limited to the frequency assignments authorized and 
internationally coordinated for the MSS system of the MSS licensee that 
seeks ATC authority.
    (iii) In the 1610-1626.5 MHz/2483.5-2500 MHz bands, ATC operations 
are limited to the 1610-1617.775 MHz, 1621.35-1626.5 MHz, and 2483.5-
2495 MHz bands and to the specific frequencies authorized for use by the 
MSS licensee that seeks ATC authority.
    (3) ATC operations shall not exceed the geographical coverage area 
of the Mobile-Satellite Service network of the applicant for ATC 
authority.
    (4) ATC base stations shall comply with all applicable antenna and 
structural clearance requirements established in part 17 of this 
chapter.
    (5) ATC base stations and mobile terminals shall comply with part 1 
of this chapter, Subpart I--Procedures Implementing the National 
Environmental Policy Act of 1969, including the guidelines for human 
exposure to radio frequency electromagnetic fields as defined in 
Sec. Sec.  1.1307(b) and 1.1310 of this chapter for PCS networks.
    (6) ATC base station operations shall use less than all available 
MSS frequencies when using all available frequencies for ATC base 
station operations would exclude otherwise available signals from MSS 
space-stations.
    (b) Applicants for an ancillary terrestrial component shall 
demonstrate that the applicant does or will comply with the following 
criteria through certification:
    (1) Geographic and temporal coverage. (i) [Reserved]
    (ii) For the L-band, an applicant must demonstrate that it can 
provide space-segment service covering all 50 states, Puerto Rico, and 
the U.S. Virgin Islands one-hundred percent of the time, unless it is 
not technically possible for the MSS operator to meet the coverage 
criteria from its orbital position.
    (iii) For the 1.6/2.4 GHz Mobile-Satellite Service bands, an 
applicant must demonstrate that it can provide space-segment service to 
all locations as far north as 70[deg] North latitude and as far south as 
55[deg] South latitude for at least seventy-five percent of every 24-
hour period, i.e., that at least one satellite will be visible above the 
horizon at an elevation angle of at least 5[deg] for at least 18 hours 
each day, and on a continuous basis throughout the fifty states, Puerto 
Rico and the U.S. Virgin Islands, i.e., that at least one satellite will 
be visible above the horizon at an elevation angle of at least 5[deg] at 
all times.
    (2) Replacement satellites. (i) Operational NGSO MSS ATC systems 
shall maintain an in-orbit spare satellite.
    (ii) Operational GSO MSS ATC systems shall maintain a spare 
satellite on the ground within one year of commencing operations and 
launch it into orbit during the next commercially reasonable launch 
window following a satellite failure.
    (iii) All MSS ATC licensees must report any satellite failures, 
malfunctions or outages that may require satellite replacement within 
ten days of their occurrence.
    (3) Commercial availability. Mobile-satellite service must be 
commercially available (viz., offering services for a fee) in accordance 
with the coverage requirements that pertain to each band

[[Page 206]]

as a prerequisite to an MSS licensee's offering ATC service.
    (4) Integrated services. MSS ATC licensees shall offer an integrated 
service of MSS and MSS ATC. Applicants for MSS ATC may establish an 
integrated service offering by affirmatively demonstrating that:
    (i) The MSS ATC operator will use a dual-mode handset that can 
communicate with both the MSS network and the MSS ATC component to 
provide the proposed ATC service; or
    (ii) Other evidence establishing that the MSS ATC operator will 
provide an integrated service offering to the public.
    (5) In-band operation. (i) [Reserved]
    (ii) In the 1.6/2.4 GHz Mobile-Satellite Service bands, MSS ATC is 
limited to no more than 7.775 MHz of spectrum in the L-band and 11.5 MHz 
of spectrum in the S-band. Licensees in these bands may implement ATC 
only on those channels on which MSS is authorized, consistent with the 
1.6/2.4 GHz Mobile-Satellite Service band-sharing arrangement.
    (iii) In the L-band, MSS ATC is limited to those frequency 
assignments available for MSS use in accordance with the Mexico City 
Memorandum of Understanding, its successor agreements or the result of 
other organized efforts of international coordination.
    (c) Equipment certification. (1) Each ATC mobile station utilized 
for operation under this part and each transmitter marketed, as set 
forth in Sec.  2.803 of this chapter, must be of a type that has been 
authorized by the Commission under its certification procedure for use 
under this part.
    (2) Any manufacturer of radio transmitting equipment to be used in 
these services may request equipment authorization following the 
procedures set forth in subpart J of part 2 of this chapter. Equipment 
authorization for an individual transmitter may be requested by an 
applicant for a station authorization by following the procedures set 
forth in part 2 of this chapter.
    (3) Licensees and manufacturers shall ensure compliance with the 
Commission's radio frequency exposure requirements in Sec. Sec.  
1.1307(b), 2.1091, and 2.1093 of this chapter, as appropriate. An 
Environmental Assessment may be required if RF radiation from the 
proposed facilities would, in combination with radiation from other 
sources, cause RF power density or field strength in an accessible area 
to exceed the applicable limits specified in Sec.  1.1310 of this 
chapter. Applications for equipment authorization of mobile or portable 
devices operating under this section must contain a statement confirming 
compliance with these requirements. Technical information showing the 
basis for this statement must be submitted to the Commission upon 
request.
    (4) Applications for equipment authorization of terrestrial low-
power system equipment that will operate in the 2483.5-2495 MHz band 
shall demonstrate the following:
    (i) The transmitted signal is digitally modulated;
    (ii) The 6 dB bandwidth is at least 500 kHz;
    (iii) The maximum transmit power is no more than 1 W with a peak 
EIRP of no more than 6 dBW;
    (iv) The maximum power spectral density conducted to the antenna is 
not greater than 8 dBm in any 3 kHz band during any time interval of 
continuous transmission;
    (v) Emissions below 2483.5 MHz are attenuated below the transmitter 
power (P) measured in watts by a factor of at least 40 + 10 log (P) dB 
at the channel edge at 2483.5 MHz, 43 + 10 log (P) dB at 5 MHz from the 
channel edge, and 55 + 10 log (P) dB at X MHz from the channel edge 
where X is the greater of 6 MHz or the actual emission bandwidth.
    (vi) Emissions above 2495 MHz are attenuated below the transmitter 
power (P) measured in watts by a factor of at least 43 + 10 log (P) dB 
on all frequencies between the channel edge at 2495 MHz and X MHz from 
this channel edge and 55 + 10 log (P) dB on all frequencies more than X 
MHz from this channel edge, where X is the greater of 6 MHz or the 
actual emission bandwidth;
    (vii) Compliance with these rules is based on the use of measurement 
instrumentation employing a resolution bandwidth of 1 MHz or greater. 
However, in the 1 MHz bands immediately above and adjacent to the 2495 
MHz a

[[Page 207]]

resolution bandwidth of at least 1 percent of the emission bandwidth of 
the fundamental emission of the transmitter may be employed. If 1 
percent of the emission bandwidth of the fundamental emission is less 
than 1 MHz, the power measured must be integrated over the required 
measurement bandwidth of 1 MHz. A resolution bandwidth narrower than 1 
MHz is permitted to improve measurement accuracy, provided the measured 
power is integrated over the full required measurement bandwidth (i.e., 
1 MHz). The emission bandwidth of the fundamental emission of a 
transmitter is defined as the width of the signal between two points, 
one below the carrier center frequency and one above the carrier center 
frequency, outside of which all emissions are attenuated at least 26 dB 
below the transmitter power. When an emission outside of the authorized 
bandwidth causes harmful interference, the Commission may, at its 
discretion, require greater attenuation than specified in this section; 
and

    Note to paragraph (c)(4): Systems meeting the requirements set forth 
in this section are deemed to have also met the requirements of Sec.  
25.254(a) through (d). No further demonstration is needed for these 
systems with respect to Sec.  25.254(a)-(d).

    (d) Applicants for an ancillary terrestrial component authority 
shall demonstrate that the applicant does or will comply with the 
provisions of Sec.  1.924 of this chapter and Sec. Sec.  25.203(e) 
through 25.203(g) and with Sec.  25.253 or Sec.  25.254, as appropriate, 
through certification or explanatory technical exhibit.
    (e) Except as provided for in paragraphs (f) and (g) of this 
section, no application for an ancillary terrestrial component shall be 
granted until the applicant has demonstrated actual compliance with the 
provisions of paragraph (b) of this section. Upon receipt of ATC 
authority, all ATC licensees shall ensure continued compliance with this 
section and Sec.  25.253 or Sec.  25.254, as appropriate.
    (f) Special provision for operational MSS systems. Applicants for 
MSS ATC authority with operational MSS systems that are in actual 
compliance with the requirements prescribed in paragraphs (b)(1), 
(b)(2), and (b)(3) of this section at the time of application may elect 
to satisfy the requirements of paragraphs (b)(4) and (b)(5) of this 
section prospectively by providing a substantial showing in its 
certification regarding how the applicant will comply with the 
requirements of paragraphs (b)(4) and (b)(5) of this section. 
Notwithstanding Sec.  25.117(f) and paragraph (e) of this section, the 
Commission may grant an application for ATC authority based on such a 
prospective substantial showing if the Commission finds that operations 
consistent with the substantial showing will result in actual compliance 
with the requirements prescribed in paragraphs (b)(4) and (b)(5) of this 
section. An MSS ATC applicant that receives a grant of ATC authority 
pursuant to this paragraph (f) shall notify the Commission within 30 
days once it begins providing ATC service. This notification must take 
the form of a letter formally filed with the Commission in the 
appropriate MSS license docket and shall contain a certification that 
the MSS ATC service is consistent with its ATC authority.
    (g) Special provisions for terrestrial low-power systems in the 
2483.5-2495 MHz band. (1) An operational MSS system that applies for 
authority to deploy ATC in the 2483.5-2495 MHz band for terrestrial low-
power operations satisfying the equipment certification requirements of 
paragraph (c)(4) of this section is not required to demonstrate 
compliance with paragraph (b) of this section, except to demonstrate the 
commercial availability of MSS, without regard to coverage requirements.
    (2) An ATC licensee seeking to modify its license to add authority 
to operate a terrestrial low-power network shall certify in its 
modification application that its operations will utilize a Network 
Operating System (NOS), consisting of a network management system 
located at an operations center or centers. The NOS shall have the 
technical capability to address and resolve interference issues related 
to the licensee's network operations by reducing operational power; 
adjusting operational frequencies; shutting off operations; or any other 
appropriate means. The NOS shall also have the ability to resolve 
interference from the

[[Page 208]]

terrestrial low-power network to the licensee's MSS operations and to 
authorize access points to the network, which in turn may authorize 
access to the network by end-user devices. The NOS operations center 
shall have a point of contact in the United States available 24 hours a 
day, seven days a week, with a phone number and address made publicly-
available by the licensee.
    (3) All access points operating in the 2483.5-2495 MHz band shall 
only operate when authorized by the ATC licensee's NOS, and all client 
devices operating in the 2483.5-2495 MHz band shall only operate when 
under the control of such access points.
    (h) Spectrum leasing. Leasing of spectrum rights by MSS licensees or 
system operators to spectrum lessees for ATC use is subject to the rules 
for spectrum manager leasing arrangements (see Sec.  1.9020) as set 
forth in part 1, subpart X of the rules (see Sec.  1.9001 et seq.). In 
addition, at the time of the filing of the requisite notification of a 
spectrum manager leasing arrangement using Form 608 (see Sec. Sec.  
1.9020(e) and 1.913(a)(5)), both parties to the proposed arrangement 
must have a complete and accurate Form 602 (see Sec.  1.913(a)(2)) on 
file with the Commission.

Sec.  25.157  Consideration of applications for NGSO-like satellite
operation.

    (a) This section specifies the procedures for considering license 
applications for ``NGSO-like'' satellite operation, except as provided 
in paragraphs (b) and (i) of this section. For purposes of this section, 
the term ``NGSO-like satellite operation'' means:
    (1) Operation of any NGSO satellite system; and
    (2) Operation of a GSO MSS satellite to communicate with earth 
stations with non-directional antennas.
    (b)(1) The procedures in this section do not apply to an application 
for authority to operate a replacement space station(s) that meets the 
relevant criteria in Sec.  25.165(e)(1) and (2) and that will be 
launched before the space station(s) to be replaced is retired from 
service or within a reasonable time after loss of a space station during 
launch or due to premature failure in orbit.
    (2) Paragraphs (e), (f), and (g) of this section do not apply to an 
NGSO FSS application granted with a condition to share spectrum pursuant 
to Sec.  25.261.
    (c) Each application for NGSO-like satellite operation that is 
acceptable

[[Page 212]]

for filing under Sec.  25.112, except replacement applications described 
in paragraph (b) of this section, will be reviewed to determine whether 
it is a ``competing application,'' i.e., filed in response to a public 
notice initiating a processing round, or a ``lead application,'' i.e., 
all other applications for NGSO-like satellite operation.
    (1) Competing applications that are acceptable for filing will be 
placed on public notice to provide interested parties an opportunity to 
file pleadings in response to the application pursuant to Sec.  25.154.
    (2) Lead applications that are acceptable for filing will be placed 
on public notice. This public notice will initiate a processing round, 
establish a cut-off date for competing NGSO-like satellite system 
applications, and provide interested parties an opportunity to file 
pleadings in response to the application pursuant to Sec.  25.154.
    (d) After review of each of the applications in the processing 
round, and all the pleadings filed in response to each application, the 
Commission will grant all the applications that meet the standards of 
Sec.  25.156(a), and deny the other applications.
    (e)(1) In the event that there is insufficient spectrum in the 
frequency band available to accommodate all the qualified applicants in 
a processing round, the available spectrum will be divided equally among 
the licensees whose applications are granted pursuant to paragraph (d) 
of this section, except as set forth in paragraph (e)(2) of this 
section.
    (2) In cases where one or more applicants apply for less spectrum 
than they would be warranted under paragraph (e)(1) of this section, 
those applicants will be assigned the bandwidth amount they requested in 
their applications. In those cases, the remaining qualified applicants 
will be assigned the lesser of the amount of spectrum they requested in 
their applications, or the amount of spectrum that they would be 
assigned if the available spectrum were divided equally among the 
remaining qualified applicants.
    (f)(1) Each licensee will be allowed to select the particular band 
segment it wishes to use no earlier than 60 days before they plan to 
launch the first satellite in its system, and no later than 30 days 
before that date, by submitting a letter to the Secretary of the 
Commission. The licensee shall serve copies of this letter to the other 
participants in the processing round pursuant to Sec.  1.47 of this 
chapter.
    (2) The licensee shall request contiguous bandwidth in both the 
uplink and downlink band. Each licensee's bandwidth selection in both 
the uplink and downlink band shall not preclude other licensees from 
selecting contiguous bandwidth.
    (3) If two or more licensees in a processing round request the same 
band segment, all licensees other than the first one to request that 
particular band segment will be required to make another selection.
    (g)(1) In the event that a license granted in a processing round 
pursuant to this section is cancelled for any reason, the Commission 
will redistribute the bandwidth allocated to that applicant equally 
among the remaining applicants whose licenses were granted concurrently 
with the cancelled license, unless the Commission determines that such a 
redistribution would not result in a sufficient number of licensees 
remaining to make reasonably efficient use of the frequency band.
    (2) In the event that the redistribution of bandwidth set forth in 
paragraph (g)(1) of this section would not result in a sufficient number 
of licensees remaining to make reasonably efficient use of the frequency 
band, the Commission will issue a public notice initiating a processing 
round, as set forth in paragraph (c) of this section, to invite parties 
to apply for an NGSO-like satellite system license to operate in a 
portion of the bandwidth made available as a result of the cancellation 
of the initial applicant's license. Parties already holding licenses for 
NGSO-like satellite operation in that frequency band will not be 
permitted to participate in that processing round.
    (h) Services offered pursuant to an NGSO-like license in a frequency 
band granted before the Commission has adopted frequency-band-specific 
service rules for that band will be subject to the default service rules 
in Sec.  25.217.

[[Page 213]]

    (i) For consideration of license applications filed pursuant to the 
procedures described in Sec.  25.122 or Sec.  25.123, the application 
will be processed and granted in accordance with Sec. Sec.  25.150 
through 25.156, taking into consideration the information provided by 
the applicant under Sec.  25.122(d) or Sec.  25.123(c), but without a 
processing round as described in this section and without a queue as 
described in Sec.  25.158.

Sec.  25.158  Consideration of applications for GSO-like satellite 
operation.

    (a)(1) This section specifies the procedures for considering license 
applications for ``GSO-like'' satellite operation, except as provided in 
paragraph (a)(2) of this section. For purposes of this section, the term 
``GSO-like satellite operation'' means operation of a GSO satellite to 
communicate with earth stations with directional antennas, including 
operation of GSO satellites to provide MSS feeder links.
    (2) The procedures prescribed in this section do not apply to an 
application for authority to launch and operate a replacement space 
station that meets the relevant criteria in Sec.  25.165(e)(1) and 
(e)(2) and that will be launched before the space station to be replaced 
is retired from service or within a reasonable time after loss of a 
space station during launch or due to premature failure in orbit.
    (b) Except as provided in paragraph (a)(2) of this section, license 
applications for GSO-like satellite operation, including first-step 
filings pursuant to Sec.  25.110(b)(3)(i) or (ii), will be placed in a 
queue and considered in the order that they are filed, pursuant to the 
following procedure:
    (1) The application will be reviewed to determine whether it is 
acceptable for filing within the meaning of Sec.  25.112. If not, the 
application will be returned to the applicant.
    (2) If the application is acceptable for filing under Sec.  25.112, 
the application will be placed on public notice pursuant to Sec.  
25.151.
    (i) For applications filed pursuant to Sec.  25.110(b)(3)(i) or 
(b)(3)(ii), the public notice will announce that the Coordination 
Request or Appendix 30B filing has been submitted to the ITU. When 
further information is filed pursuant to Sec.  25.110(b)(3)(iii), it 
will be reviewed to determine whether it is substantially complete 
within the meaning of Sec.  25.112. If so, a second public notice will 
be issued pursuant to Sec.  25.151 to give interested parties an 
opportunity to file pleadings pursuant to Sec.  25.154.
    (ii) For any other license application for GSO-like satellite 
operation, the public notice will announce that the application has been 
found acceptable for filing and will give interested parties an 
opportunity to file pleadings pursuant to Sec.  25.154.
    (3) The application will be granted only if it meets each of the 
following criteria:
    (i) After review of the application and any pleadings filed in 
response to that application, the Commission finds that the application 
meets the standards of Sec.  25.156(a); and
    (ii) The proposed satellite will not cause harmful interference to 
any previously licensed operations.
    (c) A license applicant for GSO-like satellite operation must not 
transfer, assign, or otherwise permit any other entity to assume its 
place in any queue.
    (d) In the event that two or more applications for GSO-like 
satellite operation are mutually exclusive within the meaning of Sec.  
25.155(c), the Commission will consider those applications pursuant to 
the following procedure:
    (1) Each application will be reviewed to determine whether it is 
acceptable for filing within the meaning of Sec.  25.112. Any 
application not found acceptable for filing will be returned to the 
applicant.
    (2) All applications that are acceptable for filing will be placed 
on public notice pursuant to Sec.  25.151, and interested parties will 
be given an opportunity to file pleadings pursuant to Sec.  25.154.
    (3) Each application will be granted if it meets the criteria of 
paragraph (b)(3) of this section, and otherwise will be denied.
    (4) In the event that two or more applications are granted pursuant 
to paragraph (d)(3) of this section, the

[[Page 214]]

available bandwidth at the orbital location or locations in question 
will be divided equally among those licensees.
    (5) Licensees whose licenses are granted pursuant to paragraph 
(d)(4) of this section will be allowed to select the particular band 
segment it wishes to use no earlier than 60 days before they plan to 
launch the first satellite in its system, and no later than 30 days 
before that date, by submitting a letter to the Secretary of the 
Commission. The licensee shall serve copies of this letter to the other 
participants in the processing round pursuant to Sec.  1.47 of this 
chapter.
    (6) Licensees whose licenses are granted pursuant to paragraph 
(d)(4) of this section shall request contiguous bandwidth in both the 
uplink and downlink band. Each licensee's bandwidth selection shall not 
preclude other licensees from selecting contiguous bandwidth.
    (7) If two or more licensees whose licenses are granted pursuant to 
paragraph (d)(4) of this section request the same band segment, all 
licensees other than the first one to request that particular band 
segment will be required to make another selection.
    (e) Services offered pursuant to a GSO-like license in a frequency 
band granted before the Commission has adopted frequency-band-specific 
service rules for that band will be subject to the default service rules 
in Sec.  25.217.

[68 FR 51506, Aug. 27, 2003, as amended at 81 FR 55334, Aug. 18, 2016]



Sec.  25.159  Limits on pending applications and unbuilt satellite
systems.

    (a) [Reserved]
    (b) Applicants with an application for one NGSO-like satellite 
system license on file with the Commission in a particular frequency 
band, or one licensed-but-unbuilt NGSO-like satellite system in a 
particular frequency band, other than those filed or licensed under the 
procedures in Sec.  25.122 or Sec.  25.123, will not be permitted to 
apply for another NGSO-like satellite system license in that frequency 
band. This paragraph (b) shall not apply to applicants filing under 
Sec.  25.122 or Sec.  25.123.
    (c) If an applicant has an attributable interest in one or more 
other entities seeking one or more space station licenses, the pending 
applications and licensed-but-unbuilt satellite systems filed by those 
other entities will be counted as filed by the applicant for purposes of 
the limits on the number of pending space station applications and 
licensed-but-unbuilt satellite systems in this paragraph. For purposes 
of this paragraph, an applicant has an ``attributable interest'' in 
another entity if:
    (1) It holds equity (including all stockholdings, whether voting or 
nonvoting, common or preferred) and debt interest or interests, in the 
aggregate, exceed thirty-three (33) percent of the total asset value 
(defined as the aggregate of all equity plus all debt) of that entity, 
or
    (2) It holds a controlling interest in that entity, or is the 
subsidiary of a party holding a controlling interest in that entity, 
within the meaning of 47 CFR 1.2110(b)(2).
    (3) For purposes of paragraphs (c)(1) and (c)(2) of this section, 
ownership interests shall be calculated on a fully diluted basis, i.e., 
all agreements, such as warrants, stock options, and convertible 
debentures, will generally be treated as if the rights thereunder 
already have been fully exercised.
    (d) In the event that a licensee misses three or more milestones 
within any three-year period, the Commission will presume that the 
licensee obtained one or more of those licenses for speculative 
purposes. Unless the licensee rebuts this presumption, it will not be 
permitted to apply for a GSO-like satellite or an NGSO-like satellite 
system in any frequency band if it has two or more satellite 
applications pending, or two licensed-but-unbuilt satellite systems of 
any kind. This limit will remain in effect until the licensee provides 
adequate information to demonstrate that it is very likely to construct 
its licensed facilities if it were allowed to file more applications.
    (e) For purposes of this section, ``frequency band'' means one of 
the paired frequency bands available for satellite service listed in 
Sec.  25.202.

   Forfeiture, Termination, and Reinstatement of Station Authorization



Sec.  25.160  Administrative sanctions.

    (a) A forfeiture may be imposed for failure to operate in 
conformance with the Communications Act, license specifications, any 
conditions imposed on an authorization, or any of the Commission's rules 
and regulations; or for failure to comply with Commission requests for 
information needed to complete international coordination or for failure 
to cooperate in Commission investigations with respect to international 
coordination.
    (b) A forfeiture will be imposed and the station license may be 
terminated for the malicious transmissions of any signal that causes 
harmful interference with any other radio communications or signals.
    (c) A station license may be revoked for any repeated and willful 
violation of the kind set forth in paragraphs (a) and (b) of this 
section.
    (d) The sanctions specified in paragraphs (a), (b), and (c) of this 
section will be imposed only after the licensee has been provided an 
opportunity to be heard pursuant to titles III and V of the 
Communications Act of 1934, as amended.
    (e) For purposes of this section, the term ``repeated'' and 
``willful'' are defined as set out in section 312(f) of the 
Communications Act, 47 U.S.C. 312(f).



Sec.  25.161  Automatic termination of station authorization.

    A station authorization shall be automatically terminated in whole 
or in part without further notice to the licensee upon:
    (a)(1) The failure to meet an applicable milestone specified in 
Sec.  25.164(a) or (b), if no authorized space station is functional in 
orbit;
    (2) The failure to meet an applicable milestone specified in Sec.  
25.164(b)(1) or (2), if at least one authorized space station is 
functional in an authorized orbit, which failure will result in the 
termination of authority for the space stations not in orbit as of the 
milestone date, but allow for technically identical replacements; or
    (3) The failure to meet any other milestone or construction 
requirement imposed as a condition of authorization. In the case of a 
space station authorization when at least one authorized space station 
is functional in orbit, however, such termination will be with respect 
to only the authorization for any space stations not in orbit as of the 
milestone date.
    (b) The expiration of the license term, unless, in the case of an 
earth station license, an application for renewal of the license has 
been filed with the Commission pursuant to Sec.  25.121(e) or, in the 
case of a space station license, an application for extension of the 
license term has been filed with the Commission; or
    (c) The removal or modification of the facilities which renders the 
station not operational for more than 90 days, unless specific authority 
is requested.
    (d) The failure to maintain 50 percent of the maximum number of NGSO 
space stations authorized for service following the 9-year milestone 
period as functional space stations in authorized orbits, which failure 
will result in the termination of authority for the space stations not 
in orbit as of the date of noncompliance, but allow for technically 
identical replacements.

2017]



Sec.  25.162  Cause for termination of interference protection.

    The protection from interference afforded by the registration of a 
receiving earth station shall be automatically terminated if:
    (a) The request for registration is not submitted to the Commission 
within 3 months of the completion of the frequency coordination process, 
except as provided for in Sec.  25.203;
    (b) The receiving earth station is not constructed and placed into 
service within 6 months after completion of coordination;
    (c) The Commission finds that the station has been used less than 
50% of the time during any 12 month period;
    (d) The Commission finds that the station has been used for an 
unlawful purpose or otherwise in violation of the

[[Page 216]]

Commission's rules, regulations or policies;
    (e) The Commission finds that the actual use of the facility is 
inconsistent with what was set forth in the registrant's application; or
    (f) The Commission finds that the frequency coordination exhibit, 
upon which the granted registration is based, is incomplete or does not 
conform with established coordination procedures.



Sec.  25.163  Reinstatement.

    (a) A station authorization terminated in whole or in part under the 
provisions of Sec.  25.161 may be reinstated if the Commission, in its 
discretion, determines that reinstatement would best serve the public 
interest, convenience and necessity. Petitions for reinstatement will be 
considered only if:
    (1) The petition is filed within 30 days after the expiration date 
set forth in Sec.  25.161(a) or Sec.  25.161(b), whichever is 
applicable;
    (2) The petition explains the failure to file a timely notification 
or renewal application; and
    (3) The petition sets forth with specificity the procedures that 
have been established to ensure timely filings in the future.
    (b) A special temporary authorization shall automatically terminate 
upon the expiration date specified therein, or upon failure of the 
grantee to comply with any special terms or conditions set forth in the 
authorization. Temporary operation may be extended beyond the 
termination date only upon application to the Commission.

[56 FR 24016, May 28, 1991, as amended at 81 FR 55334, Aug. 18, 2016]



Sec.  25.164  Milestones.

    (a) The recipient of an initial license for a GSO space station, 
other than a SDARS space station, granted on or after August 27, 2003, 
must launch the space station, position it in its assigned orbital 
location, and operate it in accordance with the station authorization no 
later than five years after the grant of the license, unless a different 
schedule is established by this chapter or the Commission.
    (b)(1) The recipient of an initial authorization for an NGSO 
satellite system, other than an SDARS system, must launch 50 percent of 
the maximum number of space stations authorized for service, place them 
in their assigned orbits, and operate them in accordance with the 
station authorization no later than 6 years after the grant of the 
authorization, unless a different schedule is established by Title 47, 
Chapter I. This paragraph does not apply to replacement NGSO space 
stations as defined in Sec.  25.165(e).
    (2) A licensee that satisfies the requirement in paragraph (b)(1) of 
this section must launch the remaining space stations necessary to 
complete its authorized service constellation, place them in their 
assigned orbits, and operate each of them in accordance with the 
authorization no later than nine years after the grant of the 
authorization.
    (c)-(e) [Reserved]
    (f) A licensee subject to the requirements in paragraph (a) or (b) 
of this section must either demonstrate compliance with the applicable 
requirement or notify the Commission in writing that the requirement was 
not met, within 15 days after the specified deadline. Compliance with a 
milestone requirement in paragraph (a) or (b) of this section may be 
demonstrated by certifying pursuant to Sec.  25.121(d) that the space 
station(s) in question, has, or have, been launched and placed in the 
authorized orbital location or non-geostationary orbit(s) and that in-
orbit operation of the space station or stations has been tested and 
found to be consistent with the terms of the authorization.
    (g) Licensees of satellite systems that include both NGSO satellites 
and GSO satellites must meet the requirement in paragraph (a) of this 
section with respect to the GSO satellite(s) and the applicable 
requirements in paragraph (b) of this section with respect to the NGSO 
satellites.
    (h) In cases where the Commission grants a satellite authorization 
in different stages, such as a license for a satellite system using 
feeder links or inter-satellite links, the earliest of the

[[Page 217]]

milestone schedules will be applied to the entire satellite system.

18, 2017; 86 FR 49489, Sept. 3, 2021]



Sec.  25.165  Surety bonds.

    (a) For all space station licenses issued after September 20, 2004, 
other than licenses for SDARS space stations, space stations licensed in 
accordance with Sec.  25.122 or Sec.  25.123, and replacement space 
stations as defined in paragraph (e) of this section, the licensee must 
post a bond within 30 days of the grant of its license. Space station 
licensed in accordance with Sec.  25.122 or Sec.  25.123 must post a 
bond within one year plus 30 days of the grant of the license. Failure 
to post a bond will render the license null and void automatically.
    (1) An NGSO licensee must have on file a surety bond requiring 
payment in the event of default as defined in paragraph (c) of this 
section, in an amount, at a minimum, determined according to the 
following formula, with the resulting dollar amount rounded to the 
nearest $10,000: A = $1,000,000 + $4,000,000 * D/2192, where A is the 
amount to be paid and D is the lesser of 2192 or the number of days that 
elapsed from the date of license grant until the date when the license 
was surrendered.
    (2) A GSO licensee must have on file a surety bond requiring payment 
in the event of default as defined in paragraph (c) of this section, in 
an amount, at a minimum, determined according to the following formula, 
with the resulting dollar amount rounded to the nearest $10,000: A = 
$1,000,000 + $2,000,000 * D/1827, where A is the amount to be paid and D 
is the lesser of 1827 or the number of days that elapsed from the date 
of license grant until the date when the license was surrendered.
    (3) Licensees of satellite systems including both NGSO space 
stations and GSO space stations that will operate in the same frequency 
bands must file a surety bond requiring payment in the event of default 
as defined in paragraph (c) of this section, in an amount, at a minimum, 
to be determined according to the formula in paragraph (a)(1) of this 
section.
    (b) The licensee must use a surety company deemed acceptable within 
the meaning of 31 U.S.C. 9304 et seq. (See, e.g., Department of Treasury 
Fiscal Service, Companies Holding Certificates of Authority as 
Acceptable Sureties on Federal Bonds and As Acceptable Reinsurance 
Companies, 57 FR 29356, July 1, 1992.) The bond must name the U.S. 
Treasury as beneficiary in the event of the licensee's default. The 
licensee must provide the Commission with a copy of the performance 
bond, including all details and conditions.
    (c) A licensee will be considered to be in default with respect to a 
bond filed pursuant to paragraph (a) of this section if it surrenders 
the license before meeting an applicable milestone requirement in Sec.  
25.164(a) or (b)(1) or if it fails to satisfy any such milestone.
    (d) A licensee will be relieved of its bond obligation under 
paragraph (a) of this section upon a Commission finding that the 
licensee has satisfied the applicable milestone requirement(s) in Sec.  
25.164(a) and (b)(1) for the authorization.
    (e) A replacement space station is one that:
    (1) Is authorized to operate at an orbital location within 0.15[deg] of the assigned location of a GSO space 
station to be replaced or is authorized for NGSO operation and will 
replace an existing NGSO space station in its authorized orbit, except 
for space stations authorized under Sec.  25.122 or Sec.  25.123;
    (2) Is authorized to operate in the same frequency bands, and with 
the same coverage area as the space station to be replaced; and
    (3) Is scheduled to be launched so that it will be brought into use 
at approximately the same time as, but no later than, the existing space 
station is retired.
    (f) An applicant that has submitted a Coordination Request pursuant 
to Sec.  25.110(b)(3)(i) or an Appendix 30B filing pursuant to Sec.  
25.110(b)(3)(ii) must obtain a surety bond in the amount of $500,000 in 
accordance with the requirements in paragraph (b) of this section for 
licensees. The application will be returned as defective pursuant to 
Sec.  25.112 if a copy of the required bond is not filed with

[[Page 218]]

the Commission within 30 days after release of a public notice 
announcing that the Commission has submitted the Coordination Request or 
Appendix 30B filing to the ITU.
    (g) An applicant will be considered to be in default with respect to 
a bond filed pursuant to paragraph (f) of this section if the applicant 
fails to submit a complete, acceptable license application pursuant to 
Sec.  25.110(b)(3)(iii) for the operation proposed in the initial 
application materials filed pursuant to Sec.  25.110(b)(3)(i) or 
(b)(3)(ii) within two years of the date of submission of the initial 
application materials.

Sec.  25.172  Requirements for reporting space station control arrangements.

    (a) The operator of any space station licensed by the Commission or 
granted U.S. market access must file the following information with the 
Commission prior to commencing operation with the space station, or, in 
the case of a non-U.S.-licensed space station, prior to commencing 
operation with U.S. earth stations.
    (1) The information required by Sec.  25.171(a).
    (2) The call signs of any telemetry, tracking, and command earth 
station(s) communicating with the space station from any site in the 
United States.
    (3) The location, by city and country, of any telemetry, tracking, 
and command earth station that communicates with the space station from 
any point outside the United States.
    (4) Alternatively, instead of listing the call signs and/or 
locations of earth stations currently used for telemetry, tracking, and 
command, the space station operator may provide 24/7 contact information 
for a satellite control center and a list of the call signs of any U.S. 
earth stations, and the locations of any non-U.S. earth stations, that 
are used or may be used for telemetry, tracking, and command 
communication with the space station(s) in question.
    (b) The information required by paragraph (a) of this section must 
be filed electronically in the Commission's International Communications 
Filing System (ICFS), in the ``Other Filings'' tab of the space 
station's current authorization file. If call sign or location 
information provided pursuant to paragraph (a) of this section becomes 
invalid due to a change of circumstances, the space station operator 
must file updated information in the same manner within 30 days, except 
with respect to changes less than 30 days in duration, for which no 
update is necessary.

station licensed under this part, the operator must notify the 
Commission that such testing has been completed and certify that the 
space station's measured performance is consistent with the station 
authorization and that the space station is capable of using its 
assigned frequencies or inform the Commission of any discrepancy. The 
licensee must also indicate in the filing whether the space station has 
been placed in the assigned geostationary orbital location or non-
geostationary orbit. If the licensee files a certification pursuant to 
this paragraph before the space station has been placed in its assigned 
orbit or orbital location, the licensee must separately notify the 
Commission that the space station has been placed in such orbit or 
orbital location within 3 days after such placement and that the 
station's measured performance is consistent with the station 
authorization.

than 90 + 10 log (P) dB in a 1-megahertz bandwidth outside the 2320-2345 
MHz band, where P is average transmitter output power in watts.
    (2) Any SDARS terrestrial repeater operating at a power level equal 
to or less than 2-watt average EIRP is required to attenuate its out-of-
band emissions below the transmitter power P by a factor of not less 
than 75 + 10 log (P) dB in a 1-megahertz bandwidth outside the 2320-2345 
MHz band, where P is average transmitter output power in watts.
    (3) SDARS repeaters are permitted to attenuate out-of-band emissions 
less than the levels specified in paragraphs (h)(1) and (h)(2), of this 
section unless a potentially affected WCS licensee provides written 
notice that it intends to commence commercial service within the 
following 365 days. Starting 180 days after receipt of such written 
notice, SDARS repeaters within the area notified by the potentially 
affected WCS licensee must attenuate out-of-band emissions to the levels 
specified in paragraphs (h)(1) and (h)(2) of this section.
    (4) For the purpose of this section, a WCS licensee is potentially 
affected if it is authorized to operate a base station in the 2305-2315 
MHz or 2350-2360 MHz bands within 25 kilometers of a repeater seeking to 
operate with an out of band emission attenuation factor less than those 
prescribed in paragraphs (h)(1) or (2) of this section.
    (i) The WCS licensee is authorized to operate a base station in the 
2305-2315 MHz or 2350-2360 MHz bands in the same Major Economic Area 
(MEA) as that in which a SDARS terrestrial repeater is located.
    (ii) The WCS licensee is authorized to operate a base station in the 
2315-2320 MHz or 2345-2350 MHz bands in the same Regional Economic Area 
Grouping (REAG) as that in which a SDARS terrestrial repeater is 
located.
    (iii) A SDARS terrestrial repeater is located within 5 kilometers of 
the boundary of an MEA or REAG in which the WCS licensee is authorized 
to operate a WCS base station.
    (i) The following unwanted emissions power limits for non-
geostationary satellites operating in the inter-satellite service that 
transmit in the 22.55-23.55 GHz band shall apply in any 200 MHz of the 
23.6-24 GHz passive band, based on the date that complete advance 
publication information is received by the ITU's Radiocommunication 
Bureau:
    (1) For information received before January 1, 2020: -36 dBW.
    (2) For information received on or after January 1, 2020: -46 dBW.
    (j) For earth stations in the Fixed-Satellite Service (Earth-to-
space) that transmit in the 49.7-50.2 GHz and 50.4-50.9 GHz bands, the 
unwanted emission power in the 50.2-50.4 GHz band shall not exceed -20 
dBW/200 MHz (measured at the input of the antenna), except that the 
maximum unwanted emission

[[Page 222]]

power may be increased to -10 dBW/200 MHz for earth stations having an 
antenna gain greater than or equal to 57 dBi. These limits apply under 
clear-sky conditions. During fading conditions, the limits may be 
exceeded by earth stations when using uplink power control.

and
    (xii) A plot of great circle coordination distance contour(s) and 
rain scatter coordination distance contour(s) as determined by Sec.  
25.251.
    (3) The coordination procedures specified in Sec.  101.103 of this 
chapter and Sec.  25.251 shall be applicable except that the information 
to be provided shall be that set forth in paragraph (c)(2) of this 
section, and that the 30-day period allowed for response to a request 
for coordination may be increased to a maximum of 45 days by mutual 
consent of the parties.
    (4) Where technical problems are resolved by an agreement or 
operating arrangement between the parties that would require special 
procedures be taken to reduce the likelihood of harmful interference 
(such as the use of artificial site shielding) or would result in 
lessened quality or capacity of either system, the details thereof shall 
be contained in the application.
    (5) The Commission may, in the course of examining any application, 
require the submission of additional showings, complete with pertinent 
data and calculations in accordance with Sec.  25.251, showing that 
harmful interference is not likely to result from the proposed 
operation.
    (6) Multiple antennas in an NGSO FSS gateway earth station complex 
located within an area bounded by one second of latitude and one second 
of longitude may be regarded as a single earth station for purposes of 
coordination with terrestrial services.

ESV, VMES or an ESAA, shall also ascertain whether the great circle 
coordination distance contours and rain scatter coordination distance 
contours, computed for those values of parameters indicated in Sec.  
25.251 (Appendix 7 of the ITU RR) for international coordination, cross 
the boundaries of another Administration. In this case, the applicant 
shall furnish the Commission copies of these contours on maps drawn to 
appropriate scale for use by the Commission in effecting coordination of 
the proposed earth station with the Administration(s) affected.

\1\ Equivalent values of power flux density are calculated assuming free
  space characteristic impedance of 376.7 = 120[pi] ohms.
\2\ Space stations shall conform to the power flux density limits at the
  earth's surface specified in appropriate parts of the FCC rules, but
  in no case should exceed the above levels in any 4 kHz band for all
  angles of arrival.

    (2) Advance consultation is recommended particularly for those 
applicants who have no reliable data which indicates whether the field 
strength or power flux density figures in the above table would be 
exceeded by their proposed radio facilities (except mobile stations). In 
such instances, the following is a suggested guide for determining 
whether coordination is recommended:
    (i) All stations within 2.5 kilometers;
    (ii) Stations within 5 kilometers with 50 watts or more average 
effective radiated power (ERP) in the primary plane of polarization in 
the azimuthal direction of the Table Mountain Radio Receiving Zone;
    (iii) Stations within 15 kilometers with 1 kW or more average ERP in 
the primary plane of polarization in the azimuthal direction of Table 
Mountain Receiving Zone;
    (iv) Stations within 80 kilometers with 25 kW or more average ERP in 
the primary plane of polarization in the azimuthal direction of Table 
Mountain Receiving Zone.
    (3) Applicants concerned are urged to communicate with the Radio 
Frequency Management Coordinator, Department of Commerce, Research 
Support Services, NOAA R/E5X2, Boulder Laboratories, Boulder, CO 80303; 
telephone (303) 497-6548, in advance of filing their applications with 
the Commission.
    (4) The Commission will not screen applications to determine whether 
advance consultation has taken place. However, applicants are advised 
that such consultation can avoid objections from the Department of 
Commerce or proceedings to modify any authorization which may be granted 
which, in fact, delivers a signal at the site in excess of the field 
strength specified herein.
    (f) Notification to the National Radio Astronomy Observatory: In 
order to minimize possible harmful interference at the National Radio 
Astronomy Observatory site at Green Bank, Pocahontas County, W. Va., and 
at the Naval Radio Research Observatory site at Sugar Grove, Pendleton 
County, W. Va., any applicant for operating authority under this part 
for a new transmit or transmit-receive earth station, other than a 
mobile or temporary fixed station, within the area bounded by 
39[deg]15[min] N. on the north, 78[deg]30[min] W. on the east, 
37[deg]30[min] N. on the south and 80[deg]30[min] W. on the west or for 
modification of an existing license for such station to change the 
station's frequency, power, antenna height or directivity, or location 
must, when filing the application with the Commission, simultaneously 
notify the Director, National Radio Astronomy Observatory, P.O. Box No. 
2, Green Bank, W. Va. 24944, in writing, of the technical particulars of 
the proposed station. Such notification shall include the geographical 
coordinates of the antenna, antenna height, antenna directivity if any, 
proposed frequency, type of emission, and power. In addition, the 
applicant shall indicate in his application to the Commission the date 
notification was made to the observatory. After receipt of such 
applications, the Commission will allow a period of 20 days for comments 
or objections in response to the notifications indicated. If an 
objection to the proposed operation is received during the 20-day period 
from the National Radio Astronomy Observatory for itself or on behalf of 
the Naval Radio Research Observatory, the Commission will consider all 
aspects of the problem and take whatever action is deemed appropriate.
    (g) Protection for Federal Communications Commission monitoring 
stations:
    (1) Applicants for authority to operate a new transmitting earth 
station in the vicinity of an FCC monitoring station or to modify the 
operation of a transmitting earth station in a way that would increase 
the field strength produced at such a monitoring station above that 
previously authorized

[[Page 225]]

should consider the possible need to protect the FCC stations from 
harmful interference. Geographic coordinates of the facilities that 
require protection are listed in Sec.  0.121(c) of this chapter. 
Applications for fixed stations that will produce field strength greater 
than 10 mV/m or power flux density greater than -65.8 dBW/m\2\ in the 
authorized emission bandwidth at any of the referenced coordinates may 
be examined to determine the extent of possible interference. Depending 
on the theoretical field strength value and existing root-sum-square or 
other ambient radio field signal levels at the referenced coordinates, a 
condition to protect the monitoring station may be included in the 
station authorization.
    (2) In the event that the calculated value of the expected field 
strength exceeds 10 mV/m (-65.8 dBW/m\2\) at the reference coordinates, 
or if there is any question whether field strength levels might exceed 
the threshold value, advance consultation with the FCC to discuss any 
protection necessary should be considered. See Sec.  0.401 of this 
chapter for contact information.
    (3) Advance consultation is suggested particularly for those 
applicants who have no reliable data which indicates whether the field 
strength or power flux density figure indicated would be exceeded by 
their proposed radio facilities (except mobile stations). In such 
instances, the following is a suggested guide for determining whether an 
applicant should coordinate:
    (i) All stations within 2.5 kilometers;
    (ii) Stations within 5 kilometers with 50 watts or more average 
effective radiated power (ERP) in the primary plane of polarization in 
the azimuthal direction of the Monitoring Station;
    (iii) Stations within 15 kilometers with 1 kW or more average ERP in 
the primary plane of polarization in the azimuthal direction of the 
Monitoring Station;
    (iv) Stations within 80 kilometers with 25 kW or more average ERP in 
the primary plane of polarization in the azimuthal direction of the 
Monitoring Station.
    (4) Advance coordination for stations operating above 1000 MHz is 
recommended only where the proposed station is in the vicinity of a 
monitoring station designated as a satellite monitoring facility in 
Sec.  0.121(c) of this chapter and also meets the criteria outlined in 
paragraphs (g)(2) and (3) of this section.
    (5) The Commission will not screen applications to determine whether 
advance consultation has taken place. However, applicants are advised 
that such consultation can avoid objections from the Federal 
Communications Commission or modification of any authorization which 
will cause harmful interference.
    (h) Sites and frequencies for GSO and NGSO earth stations, operating 
in a frequency band where both have a co-primary allocation, shall be 
selected to avoid earth station antenna mainlobe-to-satellite antenna 
mainlobe coupling, between NGSO systems and between NGSO and GSO 
systems, in order to minimize the possibility of harmful interference 
between these services. Prior to filing an earth station application, in 
bands with co-primary allocations to NGSO and GSO earth stations, the 
applicant shall coordinate the proposed site and frequency usage with 
existing earth station licensees and with current earth station 
authorization applicants.
    (i) Any applicant for a new permanent transmitting fixed earth 
station to be located on the island of Puerto Rico, Desecheo, Mona, 
Vieques, or Culebra, or for modification of an existing authorization to 
change the frequency, power, antenna height, directivity, or location of 
such a station on one of these islands in a way that would increase the 
likelihood of causing interference, must notify the Interference Office, 
Arecibo Observatory, HC3 Box 53995, Arecibo, Puerto Rico 00612, in 
writing or electronically, of the technical parameters of the proposal. 
Applicants may wish to consult interference guidelines, which will be 
provided by Cornell University. Applicants who choose to transmit 
information electronically should e-mail to: [email protected].
    (1) The notification to the Interference Office, Arecibo Observatory 
shall be made prior to, or simultaneously with, the filing of the 
application with the Commission. The notification must specify the 
geographical

[[Page 226]]

coordinates of the antenna (NAD-83 datum), antenna height above ground, 
ground elevation at the antenna, antenna directivity and gain, proposed 
frequency, relevant FCC rule part, type of emission, effective radiated 
power, and whether the proposed use is itinerant. Generally, submission 
of the information in the technical portion of the FCC license 
application is adequate notification. In addition, the applicant shall 
indicate in its application to the Commission the date notification was 
made to the Arecibo Observatory.
    (2) After receipt of such applications, the Commission will allow 
the Arecibo Observatory a period of 20 days for comments or objections 
in response to the notification indicated. The applicant will be 
required to make reasonable efforts in order to resolve or mitigate any 
potential interference problem with the Arecibo Observatory and to file 
either an amendment to the application or a modification application, as 
appropriate. If the Commission determines that an applicant has 
satisfied its responsibility to make reasonable efforts to protect the 
Observatory from interference, its application may be granted.
    (3) The provisions of this paragraph do not apply to operations that 
transmit on frequencies above 15 GHz.
    (j) Applicants for NGSO 1.6/2.4 GHz Mobile-Satellite Service/
Radiodetermination-Satellite Service feeder links in the 17.7-20.2 GHz 
and 27.5-30.0 GHz bands must coordinate with licensees of FSS and 
terrestrial-service systems sharing the band to determine geographic 
protection areas around each NGSO MSS/Radiodetermination-Satellite 
Service feeder-link earth station.
    (k) An applicant for operation of an earth station, other than an 
ESV, VMES or an ESAA, that will operate with a geostationary satellite 
or non-geostationary satellite in a shared frequency band in which the 
non-geostationary system is (or is proposed to be) licensed for feeder 
links, shall demonstrate in its applications that its proposed earth 
station will not cause unacceptable interference to any other satellite 
network that is authorized to operate in the same frequency band, or 
certify that the operations of its earth station shall conform to 
established coordination agreements between the operator(s) of the space 
station(s) with which the earth station is to communicate and the 
operator(s) of any other space station licensed to use the band.
    (l) [Reserved]
    (m) Feeder links to DBS space stations:
    (1) Each applicant for a license to construct a new FSS earth 
station to provide feeder-link service to DBS space stations in the 
frequency band 17.3-17.8 GHz, or to modify any such station currently 
authorized except where the modification is for a new station within one 
kilometer of a currently-licensed earth station and modification will 
not increase the aggregate pfd, measured at any point 3-10 meters above 
the ground, above that generated by the current earth station, shall 
identify a coordination zone around its proposed new or modified earth 
station by the methodology outlined in Annex 3 of Appendix 7 of the ITU 
Radio Regulations, using the following values for the parameters in 
Table 9b of Annex 7 of Appendix 7:

Sec.  25.204  Power limits for earth stations.

    (a) In bands shared coequally with terrestrial radio communication 
services, the equivalent isotropically radiated power transmitted in any 
direction towards the horizon by an earth station, other than an ESV, 
operating in frequency bands between 1 and 15 GHz, shall not exceed the 
following limits except as provided for in paragraph (c) of this 
section:

 + 40 dBW in any 4 kHz band for [thetas] <=0[deg]
 + 40 + 3[thetas] dBW in any 4 kHz band for 0[deg] <[thetas] <=5[deg]

where [thetas] is the angle of elevation of the horizon viewed from the 
          center of radiation of the antenna of the earth station and 
          measured in degrees as positive above the horizontal plane and 
          negative below it.

    (b) In bands shared coequally with terrestrial radiocommunication 
services, the equivalent isotropically radiated power transmitted in any 
direction towards the horizon by an earth station operating in frequency 
bands above 15 GHz shall not exceed the following limits except as 
provided for in paragraph (c) of this section:

 + 64 dBW in any 1 MHz band for [thetas] <=0[deg]
 + 64 + 3 [thetas] dBW in any 1 MHz band for 0[deg] <[thetas] <=5[deg]

where [thetas] is as defined in paragraph (a) of this section.

    (c) For angles of elevation of the horizon greater than 5[deg] there 
shall be no restriction as to the equivalent isotropically radiated 
power transmitted by an earth station towards the horizon.
    (d) Notwithstanding the e.i.r.p. and e.i.r.p. density limits 
specified in the station authorization, each earth station transmission 
shall be conducted at the lowest power level that will provide the 
required signal quality as indicated in the application and further 
amended by coordination agreements.
    (e) To the extent specified in paragraphs (e)(1) through (e)(3) of 
this section, earth stations in the Fixed-Satellite Service may employ 
uplink adaptive power control or other methods of fade compensation to 
facilitate transmission of uplinks at power levels

required for desired link performance while minimizing interference 
between networks.
    (1) Except when paragraphs (e)(2) through (e)(3) of this section 
apply, transmissions from FSS earth stations in frequencies above 10 GHz 
may exceed the uplink EIRP and EIRP density limits specified in the 
station authorization under conditions of uplink fading due to 
precipitation by an amount not to exceed 1 dB above the actual amount of 
monitored excess attenuation over clear sky propagation conditions. EIRP 
levels must be returned to normal as soon as the attenuating weather 
pattern subsides.
    (2) An FSS earth station transmitting to a geostationary space 
station in the 13.77-13.78 GHz band must not generate more than 71 dBW 
EIRP in any 6 MHz band. An FSS earth station transmitting to a non-
geostationary space station in the 13.77-13.78 GHz band must not 
generate more than 51 dBW EIRP in any 6 MHz band. Automatic power 
control may be used to increase the EIRP density in a 6 MHz uplink band 
in this frequency range to compensate for rain fade, provided that the 
power flux-density at the space station does not exceed the value that 
would result when transmitting with an EIRP of 71 dBW or 51 dBW, as 
appropriate, in that 6 MHz band in clear-sky conditions.
    (3) FSS earth stations transmitting to geostationary space stations 
in the 28.35-28.6 GHz and/or 29.25-30.0 GHz bands may employ uplink 
adaptive power control or other methods of fade compensation. For 
stations employing uplink power control, the values in Sec.  
25.218(i)(1), (2), and (4) may be exceeded by up to 20 dB under 
conditions of uplink fading due to precipitation. The amount of such 
increase in excess of the actual amount of monitored excess attenuation 
over clear sky propagation conditions must not exceed 1.5 dB or 15 
percent of the actual amount of monitored excess attenuation in dB, 
whichever is larger, with a confidence level of 90 percent except over 
transient periods accounting for no more than 0.5 percent of the time 
during which the excess is no more than 4.0 dB.
    (f) An earth station in the Fixed-Satellite Service transmitting in 
the 13.75-14 GHz band must have a minimum antenna diameter of 4.5 m, and 
the EIRP of any emission in that band should be at least 68 dBW and 
should not exceed 85 dBW.

Sec.  25.205  Minimum antenna elevation angle.

    (a) Earth station antennas must not transmit at elevation angles 
less than five degrees, measured from the horizontal plane to the 
direction of maximum radiation, in a frequency band shared with 
terrestrial radio services or in a frequency band with an allocation to 
space services operating in both the Earth-to-space and space-to-Earth 
directions. In other bands, earth station antennas must not transmit at 
elevation angles less than three degrees. In some instances, it may be 
necessary to specify greater minimum elevation angles because of 
interference considerations.
    (b) ESAAs in aircraft on the ground must not transmit at elevation 
angles less than three degrees. There is no minimum angle of antenna 
elevation for ESAAs while airborne.

conditions.

    (c) For a GSO space station in the 17.7-19.7 GHz, 22.55-23.55 GHz,

    (d) In addition to the limits specified in paragraph (c) of this

density, which would be obtained under assumed free-space propagation 
conditions.

    (p) The power flux-density at the Earth's surface produced by

protection zone applicable for that site. As an alternative, a mobile 
earth station shall not operate during radio astronomy observations 
within the 1613.8-1615.8 MHz band within 100 km of the radio astronomy 
sites listed in paragraph (a)(1)(i) of this section, and within 30 km of

section if agreed to by the Mobile-Satellite Service licensee and the 
Electromagnetic Spectrum Management Unit (ESMU), National Science 
Foundation, Washington, D.C. upon a showing by the Mobile-Satellite 
Service licensee that the operation of a mobile earth station will not 
cause harmful interference to a radio astronomy observatory during 
periods of observation.
    (vi) The ESMU shall notify Mobile-Satellite Service space station 
licensees authorized to operate mobile earth stations in the 1610.0-

through (iv) of this section, as applicable, after the first position 
fix of the mobile earth station either prior to transmission or, based 
upon its location within the protection zone at the time of initial 
transmission of the mobile earth station. Once the Mobile-Satellite 
Service system determines that a mobile earth station is located within 
an RAS protection zone, the Mobile-Satellite Service system shall 
immediately initiate procedures to relocate the mobile earth station 
operations to a non-RAS frequency.
    (vii) A beacon-actuated protection zone may be used in lieu of fixed

Sec.  25.214  Technical requirements for space stations in the Satellite
Digital Audio Radio Service and associated terrestrial repeaters.

    (a) [Reserved]
    (b) Each system authorized under this section will be conditioned 
upon construction, launch and operation milestones as outlined in Sec.  
25.144(b). The failure to meet any of the milestones contained in an 
authorization will result in its cancellation, unless such failure is 
due to circumstances beyond the licensee's control or unless otherwise 
determined by the Commission upon proper showing by the licensee in any 
particular case.
    (c) Frequency assignments will be made for each satellite DARS 
system as follows:
    (1) Exclusive SDARS licenses are limited to the 2320-2345 MHz 
segment of the 2310-2360 MHz allocated bandwidth for SDARS;
    (2) Two, 12.5 MHz frequency assignments are available for satellite 
DARS: 2320.0-2332.5 MHz and 2332.5-2345.0 MHz;
    (3) Satellite DARS licensees may reduce their assigned bandwidth 
occupancy to provide telemetry beacons in their exclusive frequency 
assignments;
    (4) Each licensee may employ cross polarization within its exclusive 
frequency assignment and/or may employ cross polarized transmissions in 
frequency assignments of other satellite DARS licensees under mutual 
agreement with those licensees. Licensees who come to mutual agreement 
to use cross-polarized transmissions shall apply to the Commission for 
approval of the agreement before coordination is initiated with other 
administrations by the licensee of the exclusive frequency assignment; 
and
    (5) Feeder uplink networks are permitted in the following Fixed-
Satellite Service frequency bands: 7025-7075 MHz and 6725-7025 MHz 
(101[deg] W.L. orbital location only).
    (d) Power limit for SDARS terrestrial repeaters. (1) SDARS 
terrestrial repeaters must be operated at a power level less than or 
equal to 12-kW average EIRP, with a maximum peak-to-average power ratio 
of 13 dB.
    (2) SDARS repeaters are permitted to operate at power levels above 
12-kW average EIRP, unless a potentially affected WCS licensee provides 
written notice that it intends to commence commercial service within the 
following 365 days. Starting 180 days after receipt of such written 
notice, SDARS repeaters within the area notified by the potentially 
affected WCS licensee must be operated at a power level less than or 
equal to 12-kW average EIRP, with a maximum peak-to-average power ratio 
of 13 dB.
    (3) For the purpose of this section, a WCS licensee is potentially 
affected if it is authorized to operate a base station in the 2305-2315 
MHz or 2350-2360 MHz bands within 25 kilometers of a repeater seeking to 
operate with a power level greater than that prescribed in paragraph 
(d)(1) of this section.

    (ii) A statement from the satellite operator that it has coordinated 
the operation of the subject non-conforming earth station accessing its 
satellite(s), including its required downlink power density based on the 
information contained in the application, with all adjacent satellite 
networks within 6[deg] of orbital separation from its satellite(s), and

Sec. Sec.  25.226-25.227  [Reserved]



Sec.  25.228  Operating and coordination requirements for earth stations
in motion (ESIMs).

    (a) GSO FSS ESIM transmissions must comport with the applicable EIRP 
density limits in Sec.  25.218, unless coordinated pursuant to the 
requirements in Sec.  25.220.
    (b) Each FSS ESIM must be self-monitoring and, should a condition 
occur that would cause the ESIMs to exceed its authorized off-axis EIRP 
density limits in the case of GSO FSS ESIMs or any emission limits 
included in the licensing conditions in the case of NGSO FSS ESIMs, the 
ESIM must automatically cease transmissions within 100 milliseconds, and 
not resume transmissions until the condition that caused the ESIM to 
exceed those limits is corrected.
    (c) Each FSS ESIM must be monitored and controlled by a network 
control and monitoring center (NCMC) or equivalent facility. Each ESIM 
must comply with a ``disable transmission'' command from the NCMC within 
100 milliseconds of receiving the command. In addition, the NCMC must 
monitor the operation of each ESIM in its network, and transmit a 
``disable transmission'' command to any ESIM that operates in such a way 
as to exceed the authorized off-axis EIRP density limit for GSO FSS 
ESIMs or any emission limits included in the licensing conditions in the 
case of NGSO FSS ESIMs. The NCMC must not allow the ESIM(s) under its 
control to resume transmissions until the condition that caused the 
ESIM(s) to exceed the authorized EIRP density limits is corrected.
    (d) ESIM licensees must ensure installation of ESIM terminals on 
vehicles by qualified installers who have an understanding of the 
antenna's radiation environment and the measures best suited to maximize 
protection of the general public and persons operating the vehicle and 
equipment. An ESIM terminal exhibiting radiation exposure levels 
exceeding 1.0 mW/cm\2\ in accessible areas, such as at the exterior 
surface of the radome, must have a label attached to the surface of the 
terminal warning about the radiation hazard and must include thereon a 
diagram showing the regions around the terminal where the radiation 
levels could exceed the maximum radiation exposure limit specified in 47 
CFR 1.1310 Table 1.
    (e) The following requirements govern all ESV operations:
    (1) ESV operators must control all ESVs by a NCMC or equivalent 
facility located in the United States, except that an ESV on U.S.-
registered vessels may operate under control of a NCMC location outside 
the United States provided the ESV operator maintains a point of contact 
within the United States that will have the capability and authority to 
cause an ESV on a U.S.-registered vessel to cease transmitting if 
necessary.

[[Page 252]]

    (2) There must be a point of contact in the United States, with 
phone number and address, available 24 hours a day, seven days a week, 
with authority and ability to cease all emissions from the ESVs, either 
directly or through the facilities of a U.S. NCMC or a NCMC located in 
another country with which the United States has a bilateral agreement 
that enables such cessation of emissions.
    (3) ESV NCMC operators communicating with ESVs on vessels of foreign 
registry must maintain detailed information on each such vessel's 
country of registry and a point of contact for the relevant 
administration responsible for licensing those ESVs.
    (f) For all VMES operations, there must be a point of contact in the 
United States, with phone number and address, available 24 hours a day, 
seven days a week, with authority and ability to cease all emissions 
from the VMESs.
    (g) The following requirements govern all ESAA operations:
    (1) There must be a point of contact in the United States, with 
phone number and address, available 24 hours a day, seven days a week, 
with authority and ability to cease all emissions from the ESAAs.
    (2) All ESAA terminals operated in U.S. airspace, whether on U.S.-
registered civil aircraft or non-U.S.-registered civil aircraft, must be 
licensed by the Commission. All ESAA terminals on U.S.-registered civil 
aircraft operating outside of U.S. airspace must be licensed by the 
Commission, except as provided by section 303(t) of the Communications 
Act.
    (3) Prior to operations within a foreign nation's airspace, the ESAA 
operator must ascertain whether the relevant administration has 
operations that could be affected by ESAA terminals, and must determine 
whether that administration has adopted specific requirements concerning 
ESAA operations. When the aircraft enters foreign airspace, the ESAA 
terminal must operate under the Commission's rules, or those of the 
foreign administration, whichever is more constraining. To the extent 
that all relevant administrations have identified geographic areas from 
which ESAA operations would not affect their radio operations, ESAA 
operators may operate within those identified areas without further 
action. To the extent that the foreign administration has not adopted 
requirements regarding ESAA operations, ESAA operators must coordinate 
their operations with any potentially affected operations.
    (h) The following requirements govern all operations in the 3700-
4200 MHz (space-to-Earth) and 5925-6425 MHz (Earth-to-space) frequency 
bands of ESVs receiving from or transmitting to GSO satellites in the 
Fixed-Satellite Service:
    (1) ESVs must not operate in the 5925-6425 MHz (Earth-to-space) and 
3700-4200 MHz (space-to-Earth) frequency bands on vessels smaller than 
300 gross tons.
    (2) ESV operators transmitting in the 5925-6425 MHz (Earth-to-space) 
frequency band to GSO satellites in the Fixed-Satellite Service (FSS) 
must not seek to coordinate, in any geographic location, more than 36 
megahertz of uplink bandwidth on each of no more than two GSO FSS 
satellites.
    (3) ESVs, operating while docked, for which coordination with 
terrestrial stations in the 3700-4200 MHz band is completed in 
accordance with Sec.  25.251, will receive protection from such 
terrestrial stations in accordance with the coordination agreements, for 
180 days, renewable for 180 days.
    (4) ESVs in motion must not claim protection from harmful 
interference from any authorized terrestrial stations to which 
frequencies are already assigned, or any authorized terrestrial station 
to which frequencies may be assigned in the future in the 3700-4200 MHz 
(space-to-Earth) frequency band.
    (5) ESVs operating within 200 km from the baseline of the United 
States, or within 200 km from a U.S.-licensed fixed service offshore 
installation, must complete coordination with potentially affected U.S.-
licensed fixed service operators prior to operation. The coordination 
method and the interference criteria objective will be determined by the 
frequency coordinator. The details of the coordination must be 
maintained and available at the frequency coordinator, and must be filed 
with the Commission electronically via

[[Page 253]]

the International Bureau Filing System (http://licensing.fcc.gov/myibfs/
) to be placed on public notice. The coordination notifications must be 
filed in the form of a statement referencing the relevant call signs and 
file numbers. Operation of each individual ESV may commence immediately 
after the public notice that identifies the notification sent to the 
Commission is released. Continuance of operation of that ESV for the 
duration of the coordination term must be dependent upon successful 
completion of the normal public notice process. If, prior to the end of 
the 30-day comment period of the public notice, any objections are 
received from U.S.-licensed Fixed Service operators that have been 
excluded from coordination, the ESV licensee must immediately cease 
operation of that particular station on frequencies used by the affected 
U.S.-licensed Fixed Service station until the coordination dispute is 
resolved and the ESV licensee informs the Commission of the resolution. 
As used in this section, ``baseline'' means the line from which maritime 
zones are measured. The baseline is a combination of the low-water line 
and closing lines across the mouths of inland water bodies and is 
defined by a series of baseline points that include islands and ``low-
water elevations,'' as determined by the U.S. Department of State's 
Baseline Committee.
    (6) An ESV must automatically cease transmission if the ESV operates 
in violation of the terms of its coordination agreement, including, but 
not limited to, conditions related to speed of the vessel or if the ESV 
travels outside the coordinated area, if within 200 km from the baseline 
of the United States, or within 200 km from a U.S.-licensed fixed 
service offshore installation. Transmissions may be controlled by the 
ESV network control and monitoring center. The frequency coordinator may 
decide whether ESV operators should automatically cease transmissions if 
the vessel falls below a prescribed speed within a prescribed geographic 
area.
    (7) ESV transmissions in the 5925-6425 MHz (Earth-to-space) band 
shall not exceed an EIRP spectral density towards the radio-horizon of 
17 dBW/MHz, and shall not exceed an EIRP towards the radio-horizon of 
20.8 dBW. The ESV network shall shut-off the ESV transmitter if either 
the EIRP spectral density towards the radio-horizon or the EIRP towards 
the radio-horizon is exceeded.
    (i) For ESAA transmissions in the 14.0-14.5 GHz band from 
international airspace within line-of-sight of the territory of a 
foreign administration where fixed service networks have primary 
allocation in this band, the maximum power flux density (pfd) produced 
at the surface of the Earth by emissions from a single aircraft carrying 
an ESAA terminal must not exceed the following values unless the foreign 
Administration has imposed other conditions for protecting its fixed 
service stations:

----------------------------------------------------------------------------------------------------------------
 
----------------------------------------------------------------------------------------------------------------
-132 + 0.5 [middot] [thgr]........  dB(W/(m\2\ [middot]    For.......................  [thgr] <= 40[deg].
                                     MHz)).
-112..............................  dB(W/(m\2\ [middot]    For.......................  40[deg] <[thgr]
                                     MHz)).                                             <=90[deg].
----------------------------------------------------------------------------------------------------------------


Where: [thgr] is the angle of arrival of the radio-frequency wave 
(degrees above the horizontal) and the aforementioned limits relate to 
the pfd under free-space propagation conditions.
    (j) The following requirements govern all ESIMs transmitting to GSO 
or NGSO satellites in the Fixed-Satellite Service in the 14.0-14.5 GHz 
band.
    (1) Operations of ESIMs in the 14.0-14.2 GHz (Earth-to-space) 
frequency band within 125 km (for ESVs and VMESs) or within radio line 
of sight (for ESAAs) of the NASA TDRSS facilities on Guam (latitude 
13[deg]36[min]55[sec] N, longitude 144[deg]51[min]22[sec] E), White 
Sands, New Mexico (latitude 32[deg]20[min]59[sec] N, longitude 
106[deg]36[min]31[sec] W and latitude 32[deg]32[min]40[sec] N, longitude 
106[deg]36[min]48[sec] W), or Blossom Point, Maryland (latitude 
38[deg]25[min]44[sec] N, longitude 77[deg]05[min]02[sec] W) are subject 
to coordination with the National Aeronautics and Space Administration 
(NASA) through the National Telecommunications and Information 
Administration (NTIA) Interdepartment

[[Page 254]]

Radio Advisory Committee (IRAC). Licensees must notify the Space Bureau 
once they have completed coordination. Upon receipt of such notification 
from a licensee, the Space Bureau will issue a public notice stating 
that the licensee may commence operations within the coordination zone 
in 30 days if no party has opposed the operations. When NTIA seeks to 
provide similar protection to future TDRSS sites that have been 
coordinated through the IRAC Frequency Assignment Subcommittee process, 
NTIA will notify the Commission's Space Bureau that the site is nearing 
operational status. Upon public notice from the Space Bureau, all Ku-
band ESIM licensees must cease operations in the 14.0-14.2 GHz band 
within 125 km (for ESVs and VMESs) or within radio line of sight (for 
ESAAs) of the new TDRSS site until the licensees complete coordination 
with NTIA/IRAC for the new TDRSS facility. Licensees must notify the 
Space Bureau once they have completed coordination for the new TDRSS 
site. Upon receipt of such notification from a licensee, the Space 
Bureau will issue a public notice stating that the licensee may commence 
operations within the coordination zone in 30 days if no party has 
opposed the operations. The ESIM licensee then will be permitted to 
commence operations in the 14.0-14.2 GHz band within 125 km (for ESVs 
and VMESs) or within radio line of sight (for ESAAs) of the new TDRSS 
site, subject to any operational constraints developed in the 
coordination process.
    (2) Within 125 km (for ESVs and VMESs) or within radio line of sight 
(for ESAAs) of the NASA TDRSS facilities identified in paragraph (j)(1) 
of this section, ESIM transmissions in the 14.0-14.2 GHz (Earth-to-
space) band shall not exceed an EIRP spectral density towards the 
horizon of 12.5 dBW/MHz, and shall not exceed an EIRP towards the 
horizon of 16.3 dBW.
    (3) Operations of ESIMs in the 14.47-14.5 GHz (Earth-to-space) 
frequency band in the vicinity (for ESVs and VMESs) or within radio line 
of sight (for ESAAs) of radio astronomy service (RAS) observatories 
observing in the 14.47-14.5 GHz band are subject to coordination with 
the National Science Foundation (NSF). The appropriate NSF contact point 
to initiate coordination is Electromagnetic Spectrum Management Unit, 
NSF, Division of Astronomical Sciences, 2415 Eisenhower Avenue, 
Arlington VA 22314; Email: [email protected]. Licensees must notify the Space 
Bureau once they have completed coordination. Upon receipt of the 
coordination agreement from a licensee, the Space Bureau will issue a 
public notice stating that the licensee may commence operations within 
the coordination zone in 30 days if no party has opposed the operations.

    (4) When NTIA seeks to provide similar protection to future RAS 
sites that have been coordinated through the IRAC Frequency Assignment 
Subcommittee process, NTIA will notify the Commission's Space Bureau 
that the site is nearing operational status. Upon public notice from the 
Space Bureau, all Ku-band ESIMs licensees must cease operations in the 
14.47-14.5 GHz band within the relevant geographic zone (160 kms for 
single-dish radio observatories and Very Large Array antenna systems and 
50 kms for Very Long Baseline Array antenna systems for ESVs and VMESs, 
radio line of sight for ESAAs) of the new RAS site until the licensees 
complete coordination for the new RAS facility. Licensees must notify 
the Space Bureau once they have completed coordination for the new RAS 
site and must submit the coordination agreement to the Commission. Upon 
receipt of such notification from a licensee, the Space Bureau will 
issue a public notice stating that the licensee may commence operations 
within the coordination zone in 30 days if no party opposed the 
operations. The ESIMs licensee then will be permitted to commence 
operations in the 14.47-14.5 GHz band within the relevant coordination 
distance around the new RAS site, subject to any operational constraints 
developed in the coordination process.
    (5) ESIMs licensees must use Global Positioning Satellite-related or 
other similar position location technology to ensure compliance with the 
provisions of subparagraphs 1-3 of this paragraph.

Sec.  25.252  [Reserved]



Sec.  25.253  Special requirements for ancillary terrestrial components
operating in the 1626.5-1660.5 MHz/1525-1559 MHz bands.

    (a) An ancillary terrestrial component in these bands shall:
    (1) In any band segment coordinated for the exclusive use of an MSS 
applicant within the land area of the U.S., where there is no other L-
Band MSS satellite making use of that band segment within the visible 
portion of the geostationary arc as seen from the ATC coverage area, the 
ATC system will be limited by the in-band and out-of-band emission 
limitations contained in this section and the requirement to maintain a 
substantial MSS service.
    (2) In any band segment that is coordinated for the shared use of 
the applicant's MSS system and another MSS operator, where the 
coordination agreement existed prior to February 10, 2005 and permits a 
level of interference to the other MSS system of less than 6% [Delta]T/
T, the applicant's combined ATC

[[Page 256]]

and MSS operations shall increase the system noise level of the other 
MSS to no more then 6% [Delta]T/T. Any future coordination agreement 
between the parties governing ATC operation will supersede this 
paragraph.
    (3) In any band segment that is coordinated for the shared use of 
the applicant's MSS system and another MSS operator, where a 
coordination agreement existed prior to February 10, 2005 and permits a 
level of interference to the other MSS system of 6% [Delta]T/T or 
greater, the applicant's ATC operations may increase the system noise 
level of the other MSS system by no more than an additional 1% [Delta]T/
T. Any future coordination agreement between the parties governing ATC 
operations will supersede this paragraph.
    (4) In a band segment in which the applicant has no rights under a 
coordination agreement, the applicant may not implement ATC in that 
band.
    (b) ATC base stations shall not exceed an out-of-channel emissions 
measurement of -57.9 dBW/MHz at the edge of a MSS licensee's authorized 
and internationally coordinated MSS frequency assignment.
    (c) An applicant for an ancillary terrestrial component in these 
bands shall:
    (1) Demonstrate, at the time of application, how its ATC network 
will comply with the requirements of footnotes US308 and US315 to the 
table of frequency allocations contained in Sec.  2.106 of this chapter 
regarding priority and preemptive access to the L-band MSS spectrum by 
the aeronautical mobile-satellite en-route service (AMS(R)S) and the 
global maritime distress and safety system (GMDSS).
    (2) Coordinate with the terrestrial CMRS operators prior to 
initiating ATC transmissions when co-locating ATC base stations with 
terrestrial commercial mobile radio service (CMRS) base stations that 
make use of Global Positioning System (GPS) time-based receivers.
    (3) Provide, at the time of application, calculations that 
demonstrate the ATC system conforms to the [Delta]T/T requirements in 
paragraphs (a)(2) and (a)(3) of this section, if a coordination 
agreement that incorporates the ATC operations does not exist with other 
MSS operators.
    (d) Applicants for an ancillary terrestrial component in these bands 
must demonstrate that ATC base stations shall not:
    (1) Exceed a peak EIRP of 31.9-10*log (number of carriers) dBW/
200kHz, per sector, for each carrier in the 1525-1541.5 MHz and 1547.5-
1559 MHz frequency bands;
    (2) Exceed an EIRP in any direction toward the physical horizon (not 
to include man-made structures) of 26.9-10*log (number of carriers) dBW/
200 kHz, per sector, for each carrier in the 1525-1541.5 MHz and 1547.5-
1559 MHz frequency bands;
    (3) Exceed a peak EIRP of 23.9 -10*log(number of carriers) dBW/200 
kHz, per sector, for each carrier in the 1541.5-1547.5 MHz frequency 
band;
    (4) Exceed an EIRP toward the physical horizon (not to include man-
made structures) of 18.9-10*log(number of carriers) dBW/200 kHz, per 
sector, for each carrier in the 1541.5-1547.5 MHz frequency band;
    (5) Exceed a total power flux density level of -56.8 dBW/m\2\/200 
kHz at the edge of all airport runways and aircraft stand areas, 
including takeoff and landing paths from all carriers operating in the 
1525-1559 MHz frequency bands. The total power flux density here is the 
sum of all power flux density values associated with all carriers in a 
sector in the 1525-1559 MHz frequency band, expressed in dB(Watts/m\2\/
200 kHz). Free-space loss must be assumed if this requirement is 
demonstrated via calculation;
    (6) Exceed a total power flux density level of -56.6 dBW/ m\2\/200 
kHz at the water's edge of any navigable waterway from all carriers 
operating in the 1525-1541.5 MHz and 1547.5-1559 MHz frequency bands. 
The total power flux density here is the sum of all power flux density 
values associated with all carriers in a sector in the 1525-1541.5 MHz 
and 1547.5-1559 MHz frequency bands, expressed in dB(Watts/m\2\/200 
kHz). Free-space loss must be assumed if this requirement is 
demonstrated via calculation;
    (7) Exceed a total power flux density level of -64.6 dBW/ m\2\/200 
kHz at the

[[Page 257]]

water's edge of any navigable waterway from all carriers operating in

is the sum of all power flux density values associated with all carriers 
in a sector in the 1541.5-1547.5 MHz frequency band, expressed in 
dB(Watts/m\2\/200 kHz). Free-space loss must be assumed if this 
requirement is demonstrated via calculation;
    (8) Exceed a peak antenna gain of 16 dBi;
    (9) Generate EIRP density, averaged over any two-millisecond active 
transmission interval, greater than -70 dBW/MHz in the 1559-1605 MHz 
band or greater than a level determined by linear interpolation in the 
1605-1610 MHz band, from -70 dBW/MHz at 1605 MHz to -46 dBW/MHz at 1610 
MHz. The EIRP, averaged over any two-millisecond active transmission 
interval, of discrete out-of-band emissions of less than 700 Hz 
bandwidth from such base stations shall not exceed -80 dBW in the 1559-
1605 MHz band or exceed a level determined by linear interpolation in 
the 1605-1610 MHz band, from -80 dBW at 1605 MHz to -56 dBW at 1610 MHz. 
A root-mean-square detector function with a resolution bandwidth of one 
megahertz or equivalent and no less video bandwidth shall be used to 
measure wideband EIRP density for purposes of this rule, and narrowband 
EIRP shall be measured with a root-mean-square detector function with a 
resolution bandwidth of one kilohertz or equivalent.
    (e) Applicants for an ancillary terrestrial component in these bands 
must demonstrate, at the time of the application, that ATC base stations 
shall use left-hand-circular polarization antennas with a maximum gain 
of 16 dBi and overhead gain suppression according to the following:

------------------------------------------------------------------------
 Angle from  direction  of maximum
 gain,  in vertical plane,  above     Antenna  discrimination  pattern
        antenna  (degrees)                          (dB)
------------------------------------------------------------------------
0.................................  Gmax
5.................................  Not to Exceed Gmax -5
10................................  Not to Exceed Gmax -19
15 to 55..........................  Not to Exceed Gmax -27
55 to 145.........................  Not to Exceed Gmax -30
145 to 180........................  Not to Exceed Gmax -26
------------------------------------------------------------------------

    Where: Gmax is the maximum gain of the base station antenna in dBi.
    (f) Prior to operation, ancillary terrestrial component licensees 
shall:
    (1) Provide the Commission with sufficient information to complete 
coordination of ATC base stations with Search-and-Rescue Satellite-Aided 
Tracking (SARSAT) earth stations operating in the 1544-1545 MHz band for 
any ATC base station located either within 27 km of a SARSAT station, or 
within radio horizon of the SARSAT station, whichever is less.
    (2) Take all practicable steps to avoid locating ATC base stations 
within radio line of sight of Mobile Aeronautical Telemetry (MAT) 
receive sites in order to protect U.S. MAT systems consistent with ITU-R 
Recommendation ITU-R M.1459. MSS ATC base stations located within radio 
line of sight of a MAT receiver must be coordinated with the Aerospace 
and Flight Test Radio Coordinating Council (AFTRCC) for non-Government 
MAT receivers on a case-by-case basis prior to operation. For government 
MAT receivers, the MSS licensee shall supply sufficient information to 
the Commission to allow coordination to take place. A listing of current 
and planned MAT receiver sites can be obtained from AFTRCC for non-
Government sites and through the FCC's IRAC Liaison for Government MAT 
receiver sites.
    (g) ATC mobile terminals shall:
    (1) Be limited to a peak EIRP level of 0 dBW and an out-of-channel 
emissions of -67 dBW/4 kHz at the edge of an MSS licensee's authorized 
and internationally coordinated MSS frequency assignment.
    (2) Be operated in a fashion that takes all practicable steps to 
avoid causing interference to U.S. radio astronomy service (RAS) 
observations in the 1660-1660.5 MHz band.
    (3) Not generate EIRP density, averaged over any two-millisecond 
active transmission interval, greater than -70 dBW/MHz in the 1559-1605 
MHz band or greater than a level determined by linear interpolation in 
the 1605-1610 MHz band, from -70 dBW/MHz at 1605 MHz to -46 dBW/MHz at 
1610 MHz. The EIRP, averaged over any two-millisecond active 
transmission

[[Page 258]]

interval, of discrete out-of-band emissions of less than 700 Hz 
bandwidth from such mobile terminals shall not exceed -80 dBW in the 
1559-1605 MHz band or exceed a level determined by linear interpolation 
in the 1605-1610 MHz band, from -80 dBW at 1605 MHz to -56 dBW at 1610 
MHz. The EIRP density of carrier-off-state emissions from such mobile 
terminals shall not exceed -80 dBW/MHz in the 1559-1610 MHz band, 
averaged over a two-millisecond interval. A root-mean-square detector 
function with a resolution bandwidth of one megahertz or equivalent and 
no less video bandwidth shall be used to measure wideband EIRP density 
for purposes of this rule, and narrowband EIRP shall be measured with a 
root-mean-square detector function with a resolution bandwidth of one 
kilohertz or equivalent.
    (h) When implementing multiple base stations and/or base stations 
using multiple carriers, where any third-order intermodulation product 
of these base stations falls on an L-band MSS band coordinated for use 
by another MSS operator with rights to the coordinated band, the MSS ATC 
licensee must notify the MSS operator. The MSS operator may request 
coordination to modify the base station carrier frequencies, or to 
reduce the maximum base station EIRP on the frequencies contributing to 
the third-order intermodulation products. The threshold for this 
notification and coordination is when the sum of the calculated signal 
levels received by an MSS receiver exceeds -70 dBm. The MSS receiver 
used in these calculations can be assumed to have an antenna with 0 dBi 
gain. Free-space propagation between the base station antennas and the 
MSS terminals can be assumed and actual signal polarizations for the ATC 
signals and the MSS system may be used.

    (a) An applicant for an ancillary terrestrial component in these 
bands must demonstrate that ATC base stations shall:
    (1) Not exceed a peak EIRP of 32 dBW in 1.25 MHz;
    (2) Not cause unacceptable interference to systems identified in 
paragraph (c) of this section and, in any case, shall not exceed out-of-
channel emissions of -44.1 dBW/30 kHz at the edge of the MSS licensee's 
authorized frequency assignment;
    (3) At the time of application, that it has taken, or will take 
steps necessary to avoid causing interference to other services sharing 
the use of the 2450-2500 MHz band through frequency coordination; and
    (4) Base stations operating in frequencies above 2483.5 MHz shall 
not generate EIRP density, averaged over any two-millisecond active 
transmission interval, greater than -70 dBW/MHz in the 1559-1610 MHz 
band. The EIRP, averaged over any two-millisecond active transmission 
interval, of discrete out-of-band emissions of less than 700 Hz 
bandwidth from such base stations shall not exceed -80 dBW in the 1559-
1610 MHz band. A root-mean-square detector function with a resolution 
bandwidth of one megahertz or equivalent and no less video bandwidth 
shall be used to measure wideband EIRP density for purposes of this 
rule, and narrowband EIRP shall be measured with a root-mean-square 
detector function with a resolution bandwidth of one kilohertz or 
equivalent.
    (b) An applicant for an ancillary terrestrial component in these 
bands must demonstrate that mobile terminals shall:
    (1) Meet the requirements contained in Sec.  25.213 to protect radio 
astronomy service (RAS) observations in the 1610.6-1613.8 MHz band from 
unacceptable interference;
    (2) Observe a peak EIRP limit of 1.0 dBW in 1.25 MHz;
    (3) Observe an out-of-channel EIRP limit of -57.1 dBW/30 kHz at the

    (4) ATC mobile terminals operating in assigned frequencies in the 
1610-1626.5 MHz band shall not generate EIRP density, averaged over any 
two-millisecond active transmission interval, greater than -70 dBW/MHz 
in the 1559-1605 MHz band or greater than a

[[Page 259]]

level determined by linear interpolation in the 1605-1610 MHz band, from 
-70 dBW/MHz at 1605 MHz to -10 dBW/MHz at 1610 MHz. The EIRP, averaged 
over any two-millisecond active transmission interval, of discrete out-
of-band emissions of less than 700 Hz bandwidth from such mobile 
terminals shall not exceed -80 dBW in the 1559-1605 MHz band or exceed a 
level determined by linear interpolation in the 1605-1610 MHz band, from 
-80 dBW at 1605 MHz to -20 dBW at 1610 MHz. The EIRP density of carrier-
off-state emissions from such mobile terminals shall not exceed -80 dBW/
MHz in the 1559-1610 MHz band, averaged over a two-millisecond interval. 
A root-mean-square detector function with a resolution bandwidth of one 
megahertz or equivalent and no less video bandwidth shall be used to 
measure wideband EIRP density for purposes of this rule, and narrowband 
EIRP shall be measured with a root-mean-square detector function with a

    (c) Applicants for an ancillary terrestrial component to be used in 
conjunction with a Mobile-Satellite Service system using CDMA technology 
shall coordinate the use of the 1.6/2.4 GHz Mobile-Satellite Service 
spectrum designated for CDMA systems using the framework established by 
the ITU in Recommendation ITU-R M.1186 (incorporated by reference, see 
Sec.  25.108).
    (d) To avoid interference to an adjacent channel licensee in the 
Broadband Radio Service (BRS), the power of any ATC base station 
emission above 2495 MHz shall be attenuated below the transmitter power 
(P) measured in watts in accordance with the standards below. If these 
measures do not resolve a documented interference complaint received 
from the adjacent channel BRS licensee, the provisions of Sec.  25.255 
shall apply.
    (1) For base stations, the attenuation shall be not less than 43 + 
10 log (P) dB at the upper edge of the authorized ATC band, unless a 
documented interference complaint is received from an adjacent channel 
licensee in the BRS. Provided that a documented interference complaint 
cannot be mutually resolved between the parties, the following 
additional attenuation requirements set forth in subsections (2)-(5) 
shall apply:
    (2) If a pre-existing BRS base station suffers harmful interference 
from emissions caused by a new or modified ATC base station located 1.5 
km or more away, within 24 hours of the receipt of a documented 
interference complaint the ATC licensee must attenuate its emissions by 
at least 67 + 10 log (P) dB measured at 3 megahertz above the edge of 
the authorized ATC band, and shall immediately notify the complaining 
licensee upon implementation of the additional attenuation.
    (3) If a pre-existing BRS base station suffers harmful interference 
from emissions caused by a new or modified ATC base station located less 
than 1.5 km away, within 24 hours of the receipt of a documented 
interference complaint the ATC licensee must attenuate its emissions by 
at least 67 + 10 log (P) -20 log(Dkm/1.5) dB measured at 3 
megahertz above the edge of the authorized ATC band, or if both base 
stations are co-located, limit its undesired signal level at the pre-
existing BRS base station receiver(s) to no more than -107 dBm measured 
in a 5.5 megahertz bandwidth and shall immediately notify the 
complaining licensee upon such reduction in the undesired signal level.
    (4) If a new or modified BRS base station suffers harmful 
interference from emissions caused by a pre-existing ATC base station 
located 1.5 km or more away, within 60 days of receipt of a documented 
interference complaint the licensee of the ATC base station must 
attenuate its base station emissions by at least 67 + 10 log (P) dB 
measured at 3 megahertz above the edge of the authorized ATC band.
    (5) If a new or modified BRS base station suffers harmful 
interference from emissions caused by a pre-existing ATC base station 
located less than 1.5 km away, within 60 days of receipt of a documented 
interference complaint:
    (i) the ATC licensee must attenuate its base station emissions by at 
least 67 + 10 log (P) -20 log(Dkm/1.5) dB measured 3 
megahertz above the edge of the authorized ATC band, or
    (ii) if both base stations are co-located, the ATC licensee must 
limit its undesired signal level at the new or modified BRS base station 
receiver(s)

[[Page 260]]

to no more than -107 dBm measured in a 5.5 megahertz bandwidth.
    (6) Compliance with these rules is based on the use of measurement 
instrumentation employing a resolution bandwidth of 1 MHz or greater. 
However, in the 1 MHz bands immediately above and adjacent to the 2495 
MHz a resolution bandwidth of at least one percent of the emission 
bandwidth of the fundamental emission of the transmitter may be 
employed. A narrower resolution bandwidth is permitted in all cases to 
improve measurement accuracy, provided the measured power is integrated 
over the full required measurement bandwidth (i.e., 1 MHz or 1 percent 
of emission bandwidth, as specified). The emission bandwidth is defined 
as the width of the signal between two points, one below the carrier 
center frequency and one above the carrier center frequency, outside of 
which all emissions are attenuated at least 26 dB below the transmitter 
power. When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.
    (e) Licensees of terrestrial low-power systems operating in the 
2483.5-2495 MHz band shall operate consistent with the technical limits 
and other requirements specified in Sec.  25.149(c)(4) and (g)(2)-(3).

    Note to Sec.  25.254: The preceding rules of Sec.  25.254 are based 
on cdma2000 and IS-95 system architecture. To the extent that a 1.6/2.4 
GHz Mobile-Satellite Service licensee is able to demonstrate that the 
use of different system architectures would produce no greater potential 
interference than would be produced as a result of implementing the 
rules of this section, the licensee may apply for ATC authorization 
based on another system architecture.

Sec.  25.255  Procedures for resolving harmful interference related to 
operation of ancillary terrestrial components operating in the 
1.5/1.6 GHz and 1.6/2.4 GHz bands.

    If harmful interference is caused to other services by ancillary MSS 
ATC operations, either from ATC base stations or mobile terminals, the 
MSS ATC operator must resolve any such interference. If the MSS ATC 
operator claims to have resolved the interference and other operators 
claim that interference has not been resolved, then the parties to the 
dispute may petition the Commission for a resolution of their claims.

Sec.  25.257  Special requirements for NGSO MSS operations in the 
29.1-29.25 GHz band regarding LMDS.

    (a) Non-geostationary Mobile-Satellite Service (NGSO MSS) operators 
shall be licensed to use the 29.1-29.25 GHz band for Earth-to-space 
transmissions from feeder link earth station complexes. A ``feeder link 
earth station complex'' may include up to three (3) earth station 
groups, with each earth station group having up to four (4) antennas, 
located within a radius of 75 km of a given set of geographic 
coordinates provided by a NGSO MSS licensees or applicants pursuant to 
Sec.  101.147.
    (b) A maximum of seven (7) feeder link earth station complexes in 
the contiguous United States, Alaska and Hawaii may be placed into 
operation, in the largest 100 MSAs, in the band 29.1-29.25 GHz in 
accordance with Sec.  25.203 and Sec.  101.147 of this chapter.
    (c) One of the NGSO MSS operators licensed to use the 29.1-29.25 GHz 
band may specify geographic coordinates for a maximum of eight feeder 
link earth station complexes that transmit in the 29.1-29.25 GHz band. 
The other NGSO

[[Page 261]]

MSS operator licensed to use the 29.1-29.25 GHz band may specify 
geographic coordinates for a maximum of two feeder link earth station 
complexes that transmit in the 29.1-29.25 GHz band.
    (d) Additional NGSO MSS operators may be licensed in this band if 
the additional NGSO MSS operator shows that its system can share with 
the existing NGSO MSS systems.
    (e) All NGSO MSS operators shall cooperate fully and make reasonable 
efforts to identify mutually acceptable locations for feeder link earth 
station complexes. In this regard, any single NGSO MSS operator may 
identify only one feeder-link earth station complex protection zone in 
each category identified in Sec.  101.147(y)(2) of this chapter until 
the other NGSO MSS operator has been given an opportunity to select a 
location from the same category.

Sec.  25.258  Sharing between NGSO MSS feeder-link stations and 
GSO FSS services in the 29.25-29.5 GHz band.

    (a) Operators of NGSO MSS feeder link earth stations and GSO FSS 
earth stations in the band 29.25 to 29.5 GHz where both services have a 
co-primary allocation shall cooperate fully in order to coordinate their 
systems. During the coordination process both service operators shall 
exchange the necessary technical parameters required for coordination.
    (b) Licensed GSO FSS earth stations in the vicinity of operational 
NGSO MSS feeder-link earth station complexes must, to the maximum extent 
possible, operate with frequency/polarization selections that will 
minimize unacceptable interference with reception of GSO FSS and NGSO 
MSS uplink transmissions in the 29.25-29.5 GHz band. Earth station 
licensees operating with GSO FSS systems shall be capable of providing 
earth station locations to support coordination of NGSO MSS feeder link 
stations under paragraphs (a) and (c) of this section. Operation of 
ubiquitously deployed GSO FSS earth stations in the 29.25-29.5 GHz 
frequency band must conform to the rules contained in Sec.  25.218(i).
    (c) Applicants for authority to use the 29.25-29.5 GHz band for NGSO 
MSS feeder uplinks will have to demonstrate that their systems can share 
with GSO FSS and NGSO MSS systems that have been authorized for 
operation in that band.

Sec.  25.259  Time sharing between NOAA meteorological satellite systems
and non-voice, non-geostationary satellite systems in the 137-138 MHz band.

    (a) The space stations of a non-voice, non-geostationary Mobile-
Satellite Service (NVNG MSS) system time-sharing downlink spectrum in 
the 137-138 MHz band with National Oceanic and Atmospheric 
Administration (NOAA) satellites shall not transmit signals into the 
``protection areas'' of the NOAA satellites.
    (1) With respect to transmission in the 137.333-137.367 MHz, 
137.485-137.515 MHz, 137.605-137.635 MHz, and 137.753-137.787 MHz bands, 
the protection area for a NOAA satellite is the area on the Earth's 
surface in which the NOAA satellite is in line of sight from the ground 
at an elevation angle of five degrees or more above the horizon. No NVNG 
MSS satellite shall transmit in these bands when it is in line of sight 
at an elevation angle of zero degrees or more from any point on the 
ground within a NOAA satellite's protected area for that band.
    (2) With respect to transmission in the 137.025-137.175 MHz and 
137.825-138 MHz bands, the protection area for a NOAA satellite is the 
area on the Earth's surface in which the NOAA satellite is in line of 
sight from the ground at any elevation angle above zero degrees. No NVNG 
MSS satellite shall transmit in these bands when at a line-of-sight 
elevation angle of zero degrees or more from any point on the ground 
within a NOAA satellite's protected area for that band. In addition, 
such an NVNG MSS satellite shall cease transmitting when it is at an 
elevation angle of less than zero degrees from any such point, if 
reasonably necessary to protect reception of the NOAA satellite's 
signal.

[[Page 262]]

    (3) An NVNG MSS licensee is responsible for obtaining the ephemeris 
data necessary for compliance with these restrictions. The ephemeris 
information must be updated system-wide on at least a weekly basis. For 
calculation required for compliance with these restrictions an NVNG MSS 
licensee shall use an orbital propagator algorithm with an accuracy 
equal to or greater than the NORAD propagator used by NOAA.
    (b) An NVNG licensee time sharing spectrum in the 137-138 MHz band 
must establish a 24-hour per day contact person and telephone number so 
that claims of harmful interference into NOAA earth stations and other 
operational issues can be reported and resolved expeditiously. This 
contact information must be made available to NOAA or its designee. If 
the NTIA notifies the Commission that NOAA is receiving unacceptable 
interference from a NVNG licensee, the Commission will require such NVNG 
licensee to terminate its interfering operations immediately unless it 
demonstrates to the Commission's reasonable satisfaction, and that of 
NTIA, that it is not responsible for causing harmful interference into 
the worldwide NOAA system. An NVNG licensee assumes the risk of any 
liability or damage that it and its directors, officers, employees, 
affiliates, agents and subcontractors may incur or suffer in connection 
with an interruption of its Mobile-Satellite Service, in whole or in 
part, arising from or relating to its compliance or noncompliance with 
the requirements of this paragraph.
    (c) Each satellite in a NVNG licensee's system time-sharing spectrum 
with NOAA in the 137-138 MHz band shall automatically turn off and cease 
satellite transmissions if, after 72 consecutive hours, no reset signal 
is received from the NVNG licensee's gateway earth station and verified 
by the satellite. All satellites in such NVNG licensee's system shall be 
capable of instantaneous shutdown on any sub-band upon command from such 
NVNG licensee's gateway earth station.

Sec.  25.260  Time sharing between DoD meteorological satellite systems
and non-voice, non-geostationary satellite systems in the 400.15-401 MHz 
band.

    (a) The space stations of a non-voice, non-geostationary Mobile-
Satellite Service (NVNG MSS) system time-sharing downlink spectrum in 
the 400.15-401.0 MHz band with Department of Defense (DoD) satellites 
shall not transmit signals into the ``protection areas'' of the DoD 
satellites.
    (1) The protection area for such a DoD satellite is the area on the 
Earth's surface in which the DoD satellite is in line of sight from the 
ground at an elevation angle of five degrees or more above the horizon.
    (2) An NVNG MSS space station shall not transmit in the 400.15-401 
MHz band when at a line-of-sight elevation angle of zero degrees or more 
from any point on the ground within the protected area of a DoD 
satellite operating in that band.
    (3) An NVNG MSS licensee is responsible for obtaining the ephemeris 
data necessary for compliance with this restriction. The ephemeris 
information must be updated system-wide at least once per week. For 
calculation required for compliance with this restriction an NVNG MSS 
licensee shall use an orbital propagator algorithm with an accuracy 
equal to or greater than the NORAD propagator used by DoD.
    (b) An NVNG licensee time sharing spectrum in the 400.15-401 MHz 
band must establish a 24-hour per day contact person and telephone 
number so that claims of harmful interference into DoD earth stations 
and other operational issues can be reported and resolved expeditiously. 
This contact information must be made available to DoD or its designee. 
If the NTIA notifies the Commission that DoD is receiving unacceptable 
interference from a NVNG licensee, the Commission will require such NVNG 
licensee to terminate its interfering operations immediately unless it 
demonstrates to the Commission's reasonable satisfaction, and that of 
NTIA, that it is not responsible for causing harmful interference into 
the worldwide DoD system. A NVNG licensee assumes the risk of any

[[Page 263]]

liability or damage that it and its directors, officers, employees, 
affiliates, agents and subcontractors may incur or suffer in connection 
with an interruption of its Mobile-Satellite Service, in whole or in 
part, arising from or relating to its compliance or noncompliance with 
the requirements of this paragraph.
    (c) Each satellite in a NVNG licensee's system time-sharing spectrum 
with DoD in the 400.15-401 MHz band shall automatically turn off and 
cease satellite transmissions if, after 72 consecutive hours, no reset 
signal is received from the NVNG licensee's gateway earth station and 
verified by the satellite. All satellites in such NVNG licensee's system 
shall be capable of instantaneous shutdown on any sub-band upon command 
from such NVNG licensee's gateway earth station.
    (d) Initially, a NVNG licensee time-sharing spectrum with DoD in the 
400.15-401 MHz band shall be able to change the frequency on which its 
system satellites are operating within 125 minutes of receiving 
notification from a DoD required frequency change in the 400.15-401 MHz 
band. Thereafter, when a NVNG licensee constructs additional gateway 
earth stations located outside of North and South America, it shall use 
its best efforts to decrease to 90 minutes the time required to 
implement a DoD required frequency change. A NVNG licensee promptly 
shall notify the Commission and NTIA of any decrease in the time it 
requires to implement a DoD required frequency change.
    (e) Once a NVNG licensee time-sharing spectrum with DoD in the 
400.15-401 MHz band demonstrates to DoD that it is capable of 
implementing a DoD required frequency change within the time required 
under paragraph (d) of this section, thereafter, such NVNG licensee 
shall demonstrate its capability to implement a DoD required frequency 
change only once per year at the instruction of DoD. Such demonstrations 
shall occur during off-peak hours, as determined by the NVNG licensee, 
unless otherwise agreed by the NVNG licensee and DoD. Such NVNG licensee 
will coordinate with DoD in establishing a plan for such a 
demonstration. In the event that a NVNG licensee fails to demonstrate to 
DoD that it is capable of implementing a DoD required frequency change 
in accordance with a demonstration plan established by DoD and the NVNG 
licensee, upon the Commission's receipt of a written notification from 
NTIA describing such failure, the Commission shall impose additional 
conditions or requirements on the NVNG licensee's authorization as may 
be necessary to protect DoD operations in the 400.15-401 MHz downlink 
band until the Commission is notified by NTIA that the NVNG licensee has 
successfully demonstrated its ability to implement a DoD required 
frequency change. Such additional conditions or requirements may 
include, but are not limited to, requiring such NVNG licensee 
immediately to terminate its operations interfering with the DoD system.

Sec.  25.261  Sharing among NGSO FSS space stations.

    (a) Scope. This section applies to NGSO FSS operation with earth 
stations with directional antennas anywhere in the world under a 
Commission license, or in the United States under a grant of U.S. market 
access.
    (b) Coordination. NGSO FSS licensees and market access recipients 
must coordinate in good faith the use of commonly authorized frequencies 
regardless of their processing round status.
    (c) Default procedure. Absent coordination between two or more 
satellite systems, whenever the increase in system noise temperature of 
an earth station receiver, or a space station receiver for a satellite 
with on-board processing, of either system, [Delta]T/T, exceeds 6 
percent due to interference from emissions originating in the other 
system in a commonly authorized frequency band, such frequency band will 
be divided among the affected satellite networks in accordance with the 
following procedure:
    (1) Each of n (number of) satellite networks involved that were 
licensed or granted market access through the same processing round, 
except as provided in paragraph (e) of this section, must select 1/n of 
the assigned spectrum available in each of these frequency bands. The 
selection order for

[[Page 264]]

each satellite network will be determined by the date that the first 
space station in each satellite system is launched and capable of 
operating in the frequency band under consideration;
    (2) The affected station(s) of the respective satellite systems may 
operate in only the selected (1/n) spectrum associated with its 
satellite system while the [Delta]T/T of 6 percent threshold is 
exceeded;
    (3) All affected station(s) may resume operations throughout the 
assigned frequency bands once the threshold is no longer exceeded.
    (d) [Reserved]
    (e) Sunsetting. Ten years after the first authorization or grant of 
market access in a processing round, the systems approved in that 
processing round will no longer be required to protect earlier-rounds 
systems, and instead will be required to share spectrum with earlier-
round systems under paragraph (c) of this section.

operations, an NGSO FSS licensee or market access recipient must either 
certify that it has completed a coordination agreement with any 
operational NGSO FSS system licensed or granted U.S. market access in an 
earlier processing round, or submit for Commission approval a 
compatibility showing which demonstrates by use of a degraded throughput 
methodology that it will not cause harmful interference to any such 
system with which coordination has not been completed. If an earlier-
round system becomes operational after a later-round system has 
commenced operations, the later-round licensee or market access 
recipient must submit a certification of coordination or a compatibility 
showing with respect to the earlier-round system no later than 60 days 
after the earlier-round system commences operations as notified pursuant 
to Sec.  25.121(b) or otherwise.
    (1) Compatibility showings will be placed on public notice pursuant 
to Sec.  25.151(a)(13).
    (2) While a compatibility showing remains pending before the 
Commission, the submitting NGSO FSS licensee or market access recipient 
may commence operations on an unprotected, non-interference basis with 
respect to the operations of the system that is the subject of the 
showing.
    (e) Sunsetting. Ten years after the first authorization or grant of 
market access in a processing round, the systems approved in that 
processing round will no longer be required to protect earlier-rounds 
systems under paragraph (d) of this section, and instead will be 
required to share spectrum with earlier-round systems under paragraph 
(c) of this section.

Sec.  25.263  Information sharing requirements for SDARS terrestrial
repeater operators.

    This section requires SDARS licensees in the 2320-2345 MHz band to 
share information regarding the location and operation of terrestrial 
repeaters with WCS licensees in the 2305-2320 MHz and 2345-2360 MHz 
bands. Section 27.72 of this chapter requires WCS licensees to share 
information regarding the location and operation of base stations in the 
2305-2320 MHz and 2345-2360 MHz bands with SDARS licensees in the 2320-
2345 MHz band.
    (a) SDARS licensees must select terrestrial repeater sites and 
frequencies, to the extent practicable, to minimize the possibility of 
harmful interference to WCS base station operations in the 2305-2320 MHz 
and 2345-2360 MHz bands.
    (b) Notice requirements. SDARS licensees that intend to operate a 
new terrestrial repeater must, before commencing such operation, provide 
10 business days prior notice to all potentially affected Wireless 
Communications Service (WCS) licensees. SDARS licensees that intend to 
modify an existing repeater must, before commencing such modified 
operation, provide 5 business days prior notice to all potentially 
affected WCS licensees.
    (1) For purposes of this section, a ``potentially affected WCS 
licensee'' is a WCS licensee that:
    (i) Is authorized to operate a base station in the 2305-2315 MHz or 
2350-2360 MHz bands in the same Major Economic Area (MEA) as that in 
which the terrestrial repeater is to be located;
    (ii) Is authorized to operate base station in the 2315-2320 MHz or 
2345-2350 MHz bands in the same Regional Economic Area Grouping (REAG) 
as that in which the terrestrial repeater is to be located;
    (iii) In addition to the WCS licensees identified in paragraphs 
(b)(1)(i) and (ii) of this section, in cases in which the SDARS licensee 
plans to deploy or modify a terrestrial repeater within 5 kilometers of 
the boundary of an MEA or REAG in which the terrestrial repeater is to 
be located, a potentially affected WCS licensee is one that is 
authorized to operate a WCS base station in that neighboring MEA or REAG 
within 5 kilometers of the location of the terrestrial repeater.
    (2) For the purposes of this section, a business day is defined by 
Sec.  1.4(e)(2) of this chapter.
    (3) For modifications other than changes in location, a licensee may 
provide notice within 24 hours after the modified operation if the 
modification does not result in a predicted increase of the power flux 
density (PFD) at ground level by more than 1 dB since the last advance 
notice was given. If a demonstration is made by the WCS licensee that 
such modifications may cause harmful interference to WCS receivers, 
SDARS licensees will be required to provide notice 5 business days

[[Page 266]]

in advance of additional repeater modifications.
    (4) SDARS repeaters operating below 2 watts equivalent isotropically 
radiated power (EIRP) are exempt from the notice requirements set forth 
in this paragraph.
    (5) SDARS licensees are encouraged to develop separate coordination 
agreements with WCS licensees to facilitate efficient deployment of and 
coexistence between each service. To the extent the provisions of any 
such coordination agreement conflict with the requirements set forth 
herein, the procedures established under a coordination agreement will 
control. SDARS licensees must maintain a copy of any coordination 
agreement with a WCS license in their station files and disclose it to 
prospective assignees, transferees, or spectrum lessees and, upon 
request, to the Commission.
    (6) SDARS and WCS licensees may enter into agreements regarding 
alternative notification procedures.
    (c) Contents of notice. (1) Notification must be written (e.g., 
certified letter, fax, or e-mail) and include the licensee's name, and 
the name, address, and telephone number of its coordination 
representative, unless the SDARS licensee and all potentially affected 
WCS licensees reach a mutual agreement to provide notification by some 
other means. WCS licensees and SDARS licensees may establish such a 
mutually agreeable alternative notification mechanism without prior 
Commission approval, provided that they comply with all other 
requirements of this section.
    (2) Regardless of the notification method, notification must specify 
relevant technical details, including, at a minimum:
    (i) The coordinates of the proposed repeater to an accuracy of no 
less than 1 second latitude and longitude;
    (ii) The proposed operating power(s), frequency band(s), and 
emission(s);
    (iii) The antenna center height above ground and ground elevation 
above mean sea level, both to an accuracy of no less than 1 meter;
    (iv) The antenna gain pattern(s) in the azimuth and elevation planes 
that include the peak of the main beam; and
    (v) The antenna downtilt angle(s).
    (3) An SDARS licensee operating terrestrial repeaters must maintain 
an accurate and up-to-date inventory of its terrestrial repeaters 
operating above 2 watts average EIRP, including the information set 
forth in Sec.  25.263(c)(2), which shall be available upon request by 
the Commission.
    (d) Calculation of Notice Period. Notice periods are calculated from 
the date of receipt by the licensee being notified. If notification is 
by mail, the date of receipt is evidenced by the return receipt on 
certified mail. If notification is by fax, the date of receipt is 
evidenced by the notifying party's fax transmission confirmation log. If 
notification is by e-mail, the date of receipt is evidenced by a return 
e-mail receipt. If the SDARS licensee and all potentially affected WCS 
licensees reach a mutual agreement to provide notification by some other 
means, that agreement must specify the method for determining the 
beginning of the notice period.
    (e) Duty to cooperate. SDARS licensees must cooperate in good faith 
in the selection and use of new repeater sites to reduce interference 
and make the most effective use of the authorized facilities. SDARS 
licensees should provide WCS licensees as much lead time as practicable 
to provide ample time to conduct analyses and opportunity for prudent 
repeater site selection prior to SDARS licensees entering into real 
estate and tower leasing or purchasing agreements. Licensees of stations 
suffering or causing harmful interference must cooperate in good faith 
and resolve such problems by mutually satisfactory arrangements. If the 
licensees are unable to do so, the Space Bureau, in consultation with 
the Office of Engineering and Technology and the Wireless 
Telecommunications Bureau, will consider the actions taken by the 
parties to mitigate the risk of and remedy any alleged interference. In 
determining the appropriate action, the Bureau will take into account 
the nature and extent of the interference and act promptly to remedy the 
interference. The Bureau may impose restrictions on SDARS licensees, 
including specifying the transmitter power, antenna height, or other 
technical or operational measures to remedy the interference, and

[[Page 267]]

will take into account previous measures by the licensees to mitigate 
the risk of interference.

Sec.  25.264  Requirements to facilitate reverse-band operation in the 
17.3-17.8 GHz band of 17/24 GHz BSS and DBS Service space stations.

    (a) Each 17/24 GHz BSS space station applicant or licensee must 
submit a series of tables or graphs containing predicted off-axis gain 
data for each antenna that will transmit in the 17.3-17.8 GHz frequency 
band, in accordance with the following specifications. Using a Cartesian 
coordinate system wherein the X axis is tangent to the geostationary 
orbital arc with the positive direction pointing east, i.e., in the 
direction of travel of the satellite; the Y axis is parallel to a line 
passing through the geographic north and south poles of the Earth, with 
the positive direction pointing south; and the Z axis passes through the 
satellite and the center of the Earth, with the positive direction 
pointing toward the Earth, the applicant or licensee must provide the 
predicted transmitting antenna off-axis antenna gain information:
    (1) In the X-Z plane, i.e., the plane of the geostationary orbit, 
over a range of 30 degrees from the positive and 
negative X axes in increments of 5 degrees or less.
    (2) In planes rotated from the X-Z plane about the Z axis, over a 
range of 60 degrees relative to the equatorial 
plane, in increments of 10 degrees or less.
    (3) In both polarizations.
    (4) At a minimum of three measurement frequencies determined with 
respect to the entire portion of the 17.3-17.8 GHz frequency band over 
which the space station is designed to transmit: 5 MHz above the lower 
edge of the band; at the band center frequency; and 5 MHz below the 
upper edge of the band.
    (5) Over a greater angular measurement range, if necessary, to 
account for any planned spacecraft orientation bias or change in 
operating orientation relative to the reference coordinate system. The 
applicant or licensee must state the reasons for including such 
additional information.
    (6) The predictive gain information must be submitted to the 
Commission when a license application is filed for a 17/24 GHz BSS space 
station or within 60 days after completion of critical design review for 
the space station, whichever occurs later.
    (b) A 17/24 GHz BSS space station applicant or licensee must submit 
power flux density (pfd) calculations based on the predicted gain data 
submitted in accordance with paragraph (a) of this section, as follows:
    (1) The pfd calculations must be provided at the location of all 
prior-filed U.S. DBS space stations where the applicant's pfd level 
exceeds the coordination trigger of -117 dBW/m\2\/100 kHz in the 17.3-
17.8 GHz band. In this rule, the term prior-filed U.S. DBS space station 
refers to any co-frequency Direct Broadcast Satellite service space 
station for which an application was filed with the Commission, or an 
authorization was granted by the Commission, prior to the filing of the 
information and certifications required by paragraphs (a) and (b) of 
this section. The term prior-filed U.S. DBS space station does not 
include any applications (or authorizations) that have been denied, 
dismissed, or are otherwise no longer valid. Prior-filed U.S. DBS space 
stations may include foreign-licensed DBS space stations seeking 
authority to serve the United States market, but do not include foreign-
licensed DBS space stations that have not filed applications with the 
Commission for market access in the United States.
    (2) The pfd calculations must take into account the maximum 
permitted longitudinal station-keeping tolerance, orbital inclination 
and orbital eccentricity of both the 17/24 GHz BSS and DBS space 
stations, and must:
    (i) Identify each prior-filed U.S. DBS space station at whose 
location the coordination threshold pfd level of -117 dBW/m\2\/100 kHz 
is exceeded; and
    (ii) Indicate the extent to which the calculated pfd of the 17/24 
GHz space station's transmissions in the 17.3-17.8 GHz band exceed the 
threshold pfd level of -117 dBW/m\2\/100 kHz at those

[[Page 268]]

prior-filed U.S. DBS space station locations.
    (3) If the calculated pfd exceeds the threshold level of -117 dBW/
m\2\/100 kHz at the location of any prior-filed U.S. DBS space station, 
the applicant or licensee must also provide with the pfd calculations a 
certification that all affected DBS operators acknowledge and do not 
object to such higher off-axis pfd levels. No such certification is 
required in cases where the DBS and 17/24 GHz BSS assigned operating 
frequencies do not overlap.
    (4) The information and any certification required by paragraph (b) 
of this section must be submitted to the Commission when a license 
application is filed for a 17/24 GHz BSS space station or within 60 days 
after completion of critical design review for the space station, 
whichever occurs later. Otherwise, such information and certifications 
must be submitted to the Commission within 24 months after the grant of 
an operating license for a 17/24 GHz BSS space station or when the 
applicant or licensee certifies completion of critical design review, 
whichever occurs first.
    (c) No later than 2 months prior to launch, each 17/24 GHz BSS space 
station licensee must update the predicted transmitting antenna off-axis 
gain information provided in accordance with paragraph (a) of this 
section by submitting measured transmitting antenna off-axis gain 
information over the angular ranges, measurement frequencies and 
polarizations specified in paragraphs (a)(1) through (5) of this 
section. The transmitting antenna off-axis gain information should be 
measured under conditions as close to flight configuration as possible.
    (d) No later than 2 months prior to launch, or when applying for 
authority to change the location of a 17/24 GHz BSS space station that 
is already in orbit, each 17/24 GHz BSS space station licensee must 
provide pfd calculations based on the measured off-axis gain data 
submitted in accordance with paragraph (c) of this section, as follows:
    (1) The pfd calculations must be provided:
    (i) At the location of all prior-filed U.S. DBS space stations as 
defined in paragraph (b)(1) of this section, where the applicant's pfd 
level in the 17.3-17.8 GHz band exceeds the coordination trigger of -117 
dBW/m\2\/100 kHz; and
    (ii) At the location of any subsequently filed U.S. DBS space 
station where the pfd level in the 17.3-17.8 GHz band calculated on the 
basis of measured gain data exceeds -117 dBW/m\2\/100 kHz. In this rule, 
the term subsequently filed U.S. DBS space station refers to any co-
frequency Direct Broadcast Satellite service space station proposed in a 
license application filed with the Commission after the 17/24 GHz BSS 
operator submitted the predicted data required by paragraphs (a) through 
(b) of this section but before submission of the measured data required 
by this paragraph. Subsequently-filed U.S. DBS space stations may 
include foreign-licensed DBS space stations seeking authority to serve 
the United States market. The term does not include any applications (or 
authorizations) that have been denied, dismissed, or are otherwise no 
longer valid, nor does it include foreign-licensed DBS space stations 
that have not filed applications with the Commission for market access 
in the United States.
    (2) The pfd calculations must take into account the maximum 
permitted longitudinal station-keeping tolerance, orbital inclination 
and orbital eccentricity of both the 17/24 GHz BSS and DBS space 
stations, and must:
    (i) Identify each prior-filed U.S. DBS space station at whose 
location the coordination threshold pfd level of -117 dBW/m\2\/100 kHz 
is exceeded; and
    (ii) Demonstrate the extent to which the applicant's or licensee's 
transmissions in the 17.3-17.8 GHz band exceed the threshold pfd level 
of -117 dBW/m\2\/100 kHz at those prior-filed U.S. DBS space station 
locations.
    (e) If the pfd level calculated from the measured data submitted in 
accordance with paragraph (d) of this section is in excess of the 
threshold pfd level of -117 dBW/m\2\/100 kHz:
    (1) At the location of any prior-filed U.S. DBS space station as 
defined in paragraph (b)(1) of this section, then the 17/24 GHz 
broadcasting-satellite operator must either:

[[Page 269]]

    (i) Coordinate its operations that are in excess of the threshold 
pfd level of -117 dBW/m\2\/100 kHz with the affected prior-filed U.S. 
DBS space station operator, or
    (ii) Adjust its operating parameters so that at the location of the 
prior-filed U.S. DBS space station, the pfd level of -117 dBW/m\2\/100 
kHz is not exceeded.
    (2) At the location of any subsequently-filed U.S. DBS space station 
as defined in paragraph (d)(1) of this section, where the pfd level 
submitted in accordance with paragraph (d) of this section, is also in 
excess of the pfd level calculated on the basis of the predicted data 
submitted in accordance with paragraph (a) of this section that were on 
file with the Commission at the time the DBS space station application 
was filed, then the 17/24 GHz broadcasting-satellite operator must 
either:
    (i) Coordinate with the affected subsequently-filed U.S. DBS space 
station operator all of its operations that are either in excess of the 
pfd level calculated on the basis of the predicted antenna off-axis gain 
data, or are in excess of the threshold pfd level of -117 dBW/m\2\/100 
kHz, whichever is greater, or
    (ii) Adjust its operating parameters so that at the location of the 
subsequently-filed U.S. DBS space station, either the pfd level 
calculated on the basis of the predicted off-axis transmitting antenna 
gain data, or the threshold pfd level of -117 dBW/m\2\/100 kHz, 
whichever is greater, is not exceeded.
    (3) No coordination or adjustment of operating parameters is 
required in cases where the DBS and 17/24 GHz BSS operating frequencies 
do not overlap.
    (f) The 17/24 GHz BSS applicant or licensee must modify its license, 
or amend its application, as appropriate, based upon new information:
    (1) If the pfd levels submitted in accordance with paragraph (d) of 
this section, are in excess of those submitted in accordance with 
paragraph (b) of this section at the location of any prior-filed or 
subsequently-filed U.S. DBS space station as defined in paragraphs 
(b)(1) and (d)(1)of this section, or
    (2) If the 17/24 GHz BSS operator adjusts its operating parameters 
in accordance with paragraphs (e)(1)(ii) or (e)(2)(ii) or this section.
    (g) Absent an explicit agreement between operators to permit more 
closely spaced operations, U.S. authorized 17/24 GHz BSS space stations 
and U.S. authorized DBS space stations with co-frequency assignments may 
not be licensed to operate at locations separated by less than 0.2 
degrees in orbital longitude.
    (h) All operational 17/24 GHz BSS space stations must be maintained 
in geostationary orbits that:
    (1) Do not exceed 0.075[deg] of inclination.
    (2) Operate with an apogee less than or equal to 35,806 km above the 
surface of the Earth, and with a perigee greater than or equal to 35,766 
km above the surface of the Earth (i.e., an eccentricity of less than 
4.7 x 10-4).
    (i) U.S. authorized DBS networks may claim protection from space 
path interference arising from the reverse-band operations of U.S. 
authorized 17/24 GHz BSS networks to the extent that the DBS space 
station operates within the bounds of inclination and eccentricity 
listed below. When the geostationary orbit of the DBS space station 
exceeds these bounds on inclination and eccentricity, it may not claim 
protection from any additional space path interference arising as a 
result of its inclined or eccentric operations and may only claim 
protection as if it were operating within the bounds listed below:
    (1) The DBS space station's orbit does not exceed 0.075[deg] of 
inclination, and
    (2) The DBS space station's orbit maintains an apogee less than or 
equal to 35,806 km above the surface of the Earth, and a perigee greater 
than or equal to 35,766 km above the surface of the Earth (i.e., an 
eccentricity of less than 4.7 x 10-4).

Sec.  25.264  Requirements to facilitate reverse-band operation in the 
          17.3-17.8 GHz band.

    (a) Each applicant or licensee for a space station transmitting in 
the 17.3-17.8 GHz band must submit a series of tables or graphs 
containing predicted off-axis gain data for each antenna that will 
transmit in any portion of the 17.3-17.8 GHz band, in accordance with 
the following specifications. Using a Cartesian coordinate system 
wherein the X axis is tangent to the geostationary orbital arc with the 
positive direction pointing east, i.e., in the direction of travel of 
the satellite; the Y axis is parallel to a line passing through the 
geographic north and south poles of the Earth, with the positive 
direction pointing south; and the Z axis passes through the satellite 
and the center of the Earth, with the positive direction pointing toward 
the Earth, the applicant or licensee must provide the predicted 
transmitting antenna off-axis antenna gain information:

                                * * * * *

    (4) At a minimum of one measurement frequency at the center of the 
portion of the 17.3-17.8 GHz frequency band over which the space station 
is designed to transmit. Applicants or licensees must provide additional 
measurement data at 5 MHz above the lower edge of the band and/or at 5 
MHz below the upper edge of the band, upon request by the Commission 
staff.

                                * * * * *

    (6) The predictive gain information must be submitted to the 
Commission for each license application that is filed for a space 
station transmitting in any portion of the 17.3-18.8 GHz band no later 
than two years after license grant for the space station.
    (b) A space station applicant or licensee transmitting in any

    (2) The calculations must take into account the aggregate pfd levels 
at the DBS receiver at each measurement frequency arising from all 
antenna beams on the space station transmitting in the 17.3-17.8 GHz 
band. They must also take into account the maximum permitted 
longitudinal station-keeping tolerance, orbital inclination and orbital 
eccentricity of both the space station transmitting in the 17.3-17.8 GHz 
band and DBS space stations, and must:

                                * * * * *

station's transmissions in the 17.3-17.8 GHz band exceed the threshold 
pfd level of -117 dBW/m2/100 kHz at those prior-filed U.S. DBS space 
station locations.
    (3) If the calculated pfd exceeds the threshold level of -117 dBW/
m2/100 kHz at the location of any prior-filed U.S. DBS space station, 
the applicant or licensee must also provide with the pfd calculations a 
certification that all affected DBS operators acknowledge and do not 
object to such higher off-axis pfd levels. No such certification is 
required in cases where the frequencies assigned to the DBS and to the 
space station transmitting in the 17.3-17.8 GHz band do not overlap.
    (4) The information and any certification required by paragraph (b) 
of this section must be submitted to the Commission for each license 
application that is filed for a space station transmitting in any 
portion of the 17.3-17.8 GHz band no later than two years after license 
grant for the space station.
    (c) No later than two months prior to launch, each licensee of a 
space station transmitting in any portion of the 17.3-17.8 GHz band must 
update the predicted transmitting antenna off-axis gain information 
provided in accordance with paragraph (a) of this section by submitting 
measured transmitting antenna off-axis gain information over the angular 
ranges, measurement frequencies and polarizations specified in 
paragraphs (a)(1) through (5) of this section. The transmitting antenna 
off-axis gain information should be measured under conditions as close 
to flight configuration as possible. As an alternative, licensees 
authorized to operate at locations one degree or greater from a prior-
filed DBS space station may submit simulated transmitting antenna off-
axis gain data in lieu of measured data, over the same angular ranges, 
frequencies and polarizations.
    (d) No later than two months prior to launch, or when applying for 
authority to change the location of a space station transmitting in any 
portion of the 17.3-17.8 GHz band that is already in orbit, each such 
space station licensee must provide pfd calculations based on the 
measured off-axis gain data submitted in accordance with paragraph (c) 
of this section, as follows:

[[Page 271]]

    (1) * * *
    (ii) At the location of any subsequently filed U.S. DBS space 
station where the pfd level in the 17.3-17.8 GHz band calculated on the 
basis of measured gain data exceeds -117 dBW/m\2\/100 kHz. In this 
paragraph (d)(1)(ii), the term ``subsequently filed U.S. DBS space 
station'' refers to any co-frequency Direct Broadcast Satellite service 
space station proposed in a license application filed with the 
Commission after the operator of a space station transmitting in any 
portion of the 17.3-17.8 GHz band submitted the predicted data required 
by paragraphs (a) and (b) of this section but before submission of the 
measured data required by this paragraph. Subsequently filed U.S. DBS 
space stations may include foreign-licensed DBS space stations seeking 
authority to serve the United States market. The term does not include 
any applications (or authorizations) that have been denied, dismissed, 
or are otherwise no longer valid, nor does it include foreign-licensed 
DBS space stations that have not filed applications with the Commission 
for market access in the United States.
    (2) The pfd calculations must take into account the maximum 
permitted longitudinal station-keeping tolerance, orbital inclination 
and orbital eccentricity of both the transmitting 17.3-17.8 GHz and DBS 
space stations, and must:

                                * * * * *

    (e) If the aggregate pfd level calculated from the measured data 
submitted in accordance with paragraph (d) of this section is in excess 
of the threshold pfd level of -117 dBW/m2/100 kHz:
    (1) At the location of any prior-filed U.S. DBS space station as 
defined in paragraph (b)(1) of this section, then the operator of the 
space station transmitting in any portion of the 17.3-17.8 GHz band must 
either:

                                * * * * *

    (2) At the location of any subsequently filed U.S. DBS space station 
as defined in paragraph (d)(1) of this section, where the aggregate pfd 
level submitted in accordance with paragraph (d) of this section is also 
in excess of the pfd level calculated on the basis of the predicted data 
submitted in accordance with paragraph (a) of this section that were on 
file with the Commission at the time the DBS space station application 
was filed, then the operator of the space station transmitting in the 
17.3-17.8 GHz band must either:

                                * * * * *

    (3) No coordination or adjustment of operating parameters is 
required in cases where there is no overlap in frequencies assigned to 
the DBS and the space station transmitting in the 17.3-17.8 GH band.
    (f) The applicant or licensee for the space station transmitting in 
the 17.3-17.8 GHz band must modify its license, or amend its 
application, as appropriate, based upon new information:

                                * * * * *

    (2) If the operator of the space station transmitting in the 17.3-
17.8 GHz band adjusts its operating parameters in accordance with 
paragraph (e)(1)(ii) or (e)(2)(ii) or this section.
    (g) Absent an explicit agreement between operators to permit more 
closely spaced operations, U.S. authorized 17/24 GHz BSS or FSS space 
stations transmitting in the 17.3-17.8 GHz band and U.S. authorized DBS 
space stations with co-frequency assignments may not be licensed to 
operate at locations separated by less than 0.2 degrees in orbital 
longitude.
    (h) All operational space stations transmitting in the 17.3-17.8 GHz 
band must be maintained in geostationary orbits that:

                                * * * * *

    (i) U.S. authorized DBS networks may claim protection from space 
path interference arising from the reverse-band operations of U.S. 
authorized space stations transmitting in the 17.3-17.8 GHz band to the 
extent that the DBS space station operates within the bounds of 
inclination and eccentricity listed in paragraphs (i)(1) and (2) of this 
section. When the geostationary orbit of the DBS space station exceeds 
these bounds on inclination and eccentricity, it may not claim 
protection from any additional space path interference arising as a 
result of its inclined or eccentric operations and may only claim 
protection as if it were operating within the bounds listed in 
paragraphs (i)(1) and (2) of this section:

                                * * * * *



Sec.  25.265  Acceptance of interference in 2000-2020 MHz.

    (a) MSS receivers operating in the 2000-2020 MHz band must accept 
interference from lawful operations in the 1995-2000 MHz band, where 
such interference is due to:
    (1) The in-band power of any operations in 1995-2000 MHz (i.e., the 
portion of transmit power contained in the 1995-2000 MHz band); or
    (2) The portion of out-of-band emissions contained in 2000-2005 MHz.

Sec.  25.272  General inter-system coordination procedures.

    (a) Each space station licensee in the Fixed-Satellite Service shall 
establish a satellite network control center which will have the 
responsibility to do the following:
    (1) Monitor space-to-Earth transmissions in its system (thus 
indirectly monitoring uplink earth station transmissions in its system) 
and
    (2) Coordinate transmissions in its satellite system with those of 
other systems to prevent harmful interference incidents or, in the event 
of a harmful interference incident, to identify the source of the 
interference and correct the problem promptly.
    (b) [Reserved]
    (c) The transmitting earth station licensee shall provide the 
operator(s) of the satellites, on which the licensee is authorized to 
transmit, contact telephone numbers for the control center of the earth 
station and emergency telephone numbers for key personnel; a current 
file of these contacts shall be maintained at each satellite system 
control center.
    (d) An earth station licensee shall ensure that each of its 
authorized earth stations complies with the following:
    (1) The earth station licensee shall ensure that there is 
continuously available means of communications between the satellite 
network control center and the earth station operator or its remote 
control point as designated by the licensee.
    (2) The earth station operator shall notify the satellite network 
control center and receive permission from the control center before 
transmitting to the satellite or changing the basic characteristics of a 
transmission.
    (3) The earth station operator shall keep the space station licensee 
informed of all actual and planned usage.
    (4) Upon approval of the satellite network control center, the earth 
station operator may radiate an RF carrier into the designated 
transponder. Should improper illumination of the transponder or undue 
adjacent transponder interference be observed by the satellite network 
control center, the earth station operator shall immediately take 
whatever measures are needed to eliminate the problem.
    (5) The space station licensee may delegate the responsibility and 
duties of the satellite network control center to a technically 
qualified user or group of users, but the space station licensee shall 
remain ultimately responsible for the performance of those duties.

[58 FR 13421, Mar. 11, 1993, as amended at 62 FR 5931, Feb. 10, 1997; 78 
FR 8431, Feb. 6, 2013; 79 FR 8325, Feb. 12, 2014]



Sec.  25.273  Duties regarding space communications transmissions.

    (a) No person shall:
    (1) Transmit to a satellite unless the specific transmission is 
first authorized by the satellite network control center;
    (2) Conduct transmissions over a transponder unless the operator is 
authorized to transmit at that time by the satellite licensee or the 
satellite licensee's successor in interest; or
    (3) Transmit in any manner that causes unacceptable interference to 
the authorized transmission of another licensee.
    (b) Satellite operators shall provide upon request by the Commission 
and by earth station licensees authorized to transmit on their 
satellites relevant information needed to avoid unacceptable 
interference to other users, including the polarization angles for 
proper illumination of a given transponder.
    (c) Space station licensees are responsible for maintaining complete 
and accurate technical details of current and planned transmissions over 
their satellites, and shall require that authorized users of 
transponders on their satellites, whether by tariff or contract, provide 
any necessary technical information in this regard including that 
required by Sec.  25.272. Based on this information, space station 
licensees shall exchange among themselves general technical information 
concerning current and planned transmission parameters as needed to 
identify and promptly resolve any potential cases of unacceptable 
interference between their satellite systems.
    (d) Space stations authorized after May 10, 1993 which do not 
satisfy the requirements of Sec.  25.210 may be required to accept 
greater constraints in resolving interference problems than complying 
ones. The extent of these

[[Page 274]]

constraints shall be determined on a case-by-case basis.

[58 FR 13421, Mar. 11, 1993, as amended at 78 FR 8431, Feb. 6, 2013]



Sec.  25.274  Procedures to be followed in the event of harmful 
interference.

    (a) The earth station operator whose transmission is suffering 
harmful interference shall first check the earth station equipment to 
ensure that the equipment is functioning properly.
    (b) The earth station operator shall then check all other earth 
stations in the licensee's network that could be causing the harmful 
interference to ensure that none of them is the source of the 
interference and to verify that the interference is not from a local 
terrestrial source.
    (c) After the earth station operator has determined that the source 
of the interference is not another earth station operating in the same 
network or from a terrestrial source, the earth station operator shall 
contact the satellite system control center and advise the satellite 
operator of the problem. The control center operator shall observe the 
interference incident and make reasonable efforts to determine the 
source of the problem. A record shall be maintained by the control 
center operator and the earth station operator of all harmful 
interference incidents and their resolution. These records shall be made 
available to an FCC representative on request.
    (d) Where the suspected source of the interference incident is the 
operation of an earth station licensed to operate on one or more of the 
satellites in the satellite operator's system, the control center 
operator shall advise the offending earth station of the harmful 
interference incident and assist in the resolution of the problem where 
reasonably possible.
    (e) The earth station licensee whose operations are suspected of 
causing harmful interference to the operations of another earth station 
shall take reasonable measures to determine whether its operations are 
the source of the harmful interference problem. Where the operations of 
the suspect earth station are the source of the interference, the 
licensee of that earth station shall take all measures necessary to 
resolve the interference.
    (f) Where the earth station suspected of causing harmful 
interference to the operations of another earth station cannot be 
identified or is identified as an earth station operating on a satellite 
system other than the one on which the earth station suffering harmful 
interference is operating, it is the responsibility of a representative 
of the earth station suffering harmful interference to contact the 
control center of other satellite systems. The operator of the earth 
station suffering harmful interference is free to choose any 
representative to make this contact, including but not limited to the 
operator of the satellite system on which the earth station is 
operating. The operator of the earth station suffering harmful 
interference is also free to contact the control center of the other 
satellite systems directly.
    (g) At any point, the system control center operator may contact the 
Commission's Columbia Operations Center in Columbia, Maryland, to assist 
in resolving the matter. This office specializes in the resolution of 
satellite interference problems. All licensees are required to cooperate 
fully with the Commission in any investigation of interference problems.

Sec.  25.275  Particulars of operation.

    (a) Radio station authorizations issued under this part will 
normally specify only the frequency bands authorized for transmission 
and/or reception of the station.
    (b) When authorized frequency bands are specified in the station 
authorization, the licensee is authorized to transmit any number of r.f. 
carriers on any discrete frequencies within an authorized frequency band 
in accordance with the other terms and conditions of the authorization 
and the requirements of this part. Specific r.f. carrier frequencies 
within the authorized frequency band shall be selected by the licensee 
to avoid unacceptable levels of interference being caused to other 
earth, space or terrestrial stations.

[[Page 275]]

Any coordination agreements, both domestic and international, concerning 
specific frequency usage constraints, including non-use of any 
particular frequencies within the frequency bands listed in the station 
authorization, are considered to be conditions of the station 
authorization.
    (c) A license for a transmitting earth station will normally specify 
only the r.f. carriers having the highest e.i.r.p. density, the 
narrowest bandwidth, and the largest bandwidth authorized for 
transmission from that station. Unless otherwise specified in the 
station authorization, the licensee is authorized to transmit any other 
type of carrier not specifically listed which does not exceed the 
highest e.i.r.p., e.i.r.p. density and bandwidth prescribed for any 
listed emission.
    (d) Only the most sensitive emission(s) for which protection is 
being afforded from interference in the authorized receive frequency 
band(s) will be specified in the station authorization.
    (e) Transmission from an earth station of an unmodulated carrier at 
a power level sufficient to saturate a satellite transponder is 
prohibited, except as consented to by the space station licensee to 
determine transponder performance characteristics.

Sec.  25.277  Temporary fixed earth station operations.

    (a) When an earth station in the Fixed-Satellite Service is to 
remain at a single location for fewer than 6 months, the location may be 
considered to be temporary fixed. Services provided at a single location 
which are initially known to be of longer than six months' duration 
shall not be provided under a temporary fixed authorization.
    (b) When a station, other than an ESV, authorized as a temporary 
fixed earth station, is to remain at a single location for more than six 
months, application for a regular station authorization at that location 
shall be filed at least 30 days prior to the expiration of the six-month 
period.
    (c) The licensee of an earth station, other than an ESV, which is 
authorized to conduct temporary fixed operations in bands shared co-
equally with terrestrial fixed stations shall provide the following 
information to the Director of the Columbia Operations Center at 9200 
Farmhouse Lane, Columbia, Maryland 21046, and to the licensees of all 
terrestrial facilities lying within the coordination contour of the 
proposed temporary fixed earth station site before beginning 
transmissions:
    (1) The name of the person operating the station and the telephone 
number at which the operator can be reached directly;
    (2) The exact frequency or frequencies used and the type of 
emissions and power levels to be transmitted; and
    (3) The commencement and anticipated termination dates of operation 
from each location.
    (d) Except as set forth in Sec.  25.151(e), transmissions may not be 
commenced until all affected terrestrial licensees have been notified 
and the earth station operator has confirmed that unacceptable 
interference will not be caused to such terrestrial stations.
    (e) Operations of temporary fixed earth stations shall cease 
immediately upon notice of harmful interference from the Commission or 
the affected licensee.
    (f) Filing requirements concerning applications for new temporary 
fixed earth station facilities operating in frequency bands shared co-
equally with terrestrial fixed stations.
    (1) When the initial location of the temporary fixed earth station's 
operation is known, the applicant shall provide, as part of the Form 312 
application, a frequency coordination report in accordance with Sec.  
25.203 for the initial station location.

[[Page 276]]

    (2) When the initial location of the temporary fixed earth station's 
operation is not known at the time the application is filed, the

Sec.  25.279  Inter-satellite service.

    (a) Any satellite communicating with other space stations may use 
frequencies in the inter-satellite service as indicated in Sec.  2.106 
of this chapter. This does not preclude the use of other frequencies for 
such purposes as provided for in several service definitions, e.g., FSS. 
The technical details of the proposed inter-satellite link shall be 
provided in accordance with Sec.  25.114(c).
    (b) Operating conditions. In order to ensure compatible operations 
with authorized users in the frequency bands to be utilized for 
operations in the inter-satellite service, these inter-satellite service 
systems must operate in accordance with the conditions specified in this 
section.
    (1) Coordination requirements with federal government users. (i) In 
frequency bands allocated for use by the inter-satellite service that 
are also authorized for use by agencies of the federal government, the 
federal use of frequencies in the inter-satellite service frequency 
bands is under the regulatory jurisdiction of the National 
Telecommunications and Information Administration (NTIA).
    (ii) The Commission will use its existing procedures to reach 
agreement with NTIA to achieve compatible operations between federal 
government users under the jurisdiction of NTIA and inter-satellite 
service systems through frequency assignment and coordination practice 
established by NTIA and the Interdepartment Radio Advisory Committee 
(IRAC). In order to facilitate such frequency assignment and 
coordination, applicants shall provide the Commission with sufficient 
information to evaluate electromagnetic compatibility with the federal 
government users of the spectrum, and any additional information 
requested by the Commission. As part of the coordination process, 
applicants shall show that they will not cause interference to 
authorized federal government users, based upon existing system 
information provided by the government. The frequency assignment and 
coordination of the satellite system shall be completed prior to grant 
of construction authorization.
    (2) Coordination among inter-satellite service systems. Applicants 
for authority to establish inter-satellite service are encouraged to 
coordinate their proposed frequency usage with existing permittees and 
licensees in the inter-satellite service whose facilities could be 
affected by the new proposal in terms of frequency interference or 
restricted system capacity. All affected applicants, permittees, and 
licensees, shall at the direction of the Commission, cooperate fully and 
make every reasonable effort to resolve technical problems and conflicts 
that may inhibit effective and efficient use of the radio spectrum; 
however, the permittee or licensee being coordinated with is not 
obligated to suggest changes or re-engineer an applicant's proposal in 
cases involving conflicts.

mode without obtaining prior Commission authorization provided that the 
Commission is notified by letter within 30 days after the last north-
south station keeping maneuver. The notification shall include:
    (1) The operator's name;
    (2) The date of commencement of inclined orbit operation;
    (3) The initial inclination;
    (4) The rate of change in inclination per year; and
    (5) The expected end-of-life of the satellite accounting for 
inclined orbit operation, and the maneuvers specified under Sec.  25.283 
of the Commission's rules.
    (b) Licensees operating in inclined-orbit are required to:
    (1) Periodically correct the satellite attitude to achieve a 
stationary spacecraft antenna pattern on the surface of the Earth and 
centered on the satellite's designated service area;
    (2) Control all electrical interference to adjacent satellites, as a 
result of operating in an inclined orbit, to levels not to exceed that 
which would be caused by the satellite operating without an inclined 
orbit;
    (3) Not claim protection in excess of the protection that would be 
received by the satellite network operating without an inclined orbit; 
and
    (4) Continue to maintain the space station at the authorized 
longitude orbital location in the geostationary satellite arc with the 
appropriate east-west station-keeping tolerance.

Sec.  25.281  Transmitter identification requirements for video uplink
transmissions.

    (a) Earth-to-space transmissions carrying video information with 
analog modulation must be identified through use of an Automatic 
Transmitter Identification System (ATIS) with an analog identifier or a 
direct sequence spread spectrum signal.
    (1) Use of an analog identifier must be in accordance with the 
following requirements:
    (i) The ATIS signal must be a separate subcarrier that is 
automatically activated whenever any radio frequency signal is 
transmitted.

    (b) Political broadcasting requirements--
    (1) Legally qualified candidates for public office for purposes of 
this section are as defined in Sec.  73.1940 of this chapter.
    (2) DBS origination programming is defined as programming (exclusive 
of broadcast signals) carried on a DBS facility over one or more 
channels and subject to the exclusive control of the DBS provider.
    (3) Reasonable access. (i) DBS providers must comply with section 
312(a)(7) of the Communications Act of 1934, as amended, by allowing 
reasonable access to, or permitting purchase of reasonable amounts of 
time for, the use of their facilities by a legally qualified candidate 
for federal elective office on behalf of his or her candidacy.
    (ii) Weekend access. For purposes of providing reasonable access, 
DBS providers shall make facilities available for use by federal 
candidates on the weekend before the election if the DBS provider has 
provided similar access to commercial advertisers during the year 
preceding the relevant election period. DBS providers shall not 
discriminate between candidates with regard to weekend access.
    (4) Use of facilities; equal opportunities. DBS providers must 
comply with section 315 of the Communications Act of 1934, as amended, 
by providing equal opportunities to legally qualified candidates for DBS 
origination programming.
    (i) General requirements. Except as otherwise indicated in Sec.  
25.701(b)(3), no DBS provider is required to permit the use of its 
facilities by any legally qualified candidate for public office, but if 
a DBS provider shall permit any such candidate to use its facilities, it 
shall afford equal opportunities to all other candidates for that office 
to use such facilities. Such DBS provider shall have no power of 
censorship over the material broadcast by any such candidate. Appearance 
by a legally qualified candidate on any:
    (A) Bona fide newscast;
    (B) Bona fide news interview;
    (C) Bona fide news documentary (if the appearance of the candidate 
is incidental to the presentation of the subject or subjects covered by 
the news documentary); or
    (D) On the spot coverage of bona fide news events (including, but 
not limited to political conventions and activities incidental thereto) 
shall not be deemed to be use of a DBS provider's facility. (Section 
315(a) of the Communications Act.)
    (ii) Uses. As used in this section and Sec.  25.701(c), the term 
``use'' means a candidate appearance (including by voice or picture) 
that is not exempt under paragraphs (b)(3)(i)(A) through (b)(3)(i)(D) of 
this section.
    (iii) Timing of request. A request for equal opportunities must be 
submitted to the DBS provider within 1 week of the day on which the 
first prior use

[[Page 283]]

giving rise to the right of equal opportunities occurred: Provided, 
however, That where the person was not a candidate at the time of such 
first prior use, he or she shall submit his or her request within 1 week 
of the first subsequent use after he or she has become a legally 
qualified candidate for the office in question.
    (iv) Burden of proof. A candidate requesting equal opportunities of 
the DBS provider or complaining of noncompliance to the Commission shall 
have the burden of proving that he or she and his or her opponent are 
legally qualified candidates for the same public office.
    (v) Discrimination between candidates. In making time available to 
candidates for public office, no DBS provider shall make any 
discrimination between candidates in practices, regulations, facilities, 
or services for or in connection with the service rendered pursuant to 
this part, or make or give any preference to any candidate for public 
office or subject any such candidate to any prejudice or disadvantage; 
nor shall any DBS provider make any contract or other agreement that 
shall have the effect of permitting any legally qualified candidate for 
any public office to use DBS origination programming to the exclusion of 
other legally qualified candidates for the same public office.
    (c) Candidate rates--(1) Charges for use of DBS facilities. The 
charges, if any, made for the use of any DBS facility by any person who 
is a legally qualified candidate for any public office in connection 
with his or her campaign for nomination for election, or election, to 
such office shall not exceed:
    (i) During the 45 days preceding the date of a primary or primary 
runoff election and during the 60 days preceding the date of a general 
or special election in which such person is a candidate, the lowest unit 
charge of the DBS provider for the same class and amount of time for the 
same period.
    (A) A candidate shall be charged no more per unit than the DBS 
provider charges its most favored commercial advertisers for the same 
classes and amounts of time for the same periods. Any facility practices 
offered to commercial advertisers that enhance the value of advertising 
spots must be disclosed and made available to candidates upon equal 
terms. Such practices include but are not limited to any discount 
privileges that affect the value of advertising, such as bonus spots, 
time sensitive make goods, preemption priorities, or any other factors 
that enhance the value of the announcement.
    (B) The Commission recognizes non preemptible, preemptible with 
notice, immediately preemptible and run of schedule as distinct classes 
of time.
    (C) DBS providers may establish and define their own reasonable 
classes of immediately preemptible time so long as the differences 
between such classes are based on one or more demonstrable benefits 
associated with each class and are not based solely upon price or 
identity of the advertiser. Such demonstrable benefits include, but are 
not limited to, varying levels of preemption protection, scheduling 
flexibility, or associated privileges, such as guaranteed time sensitive 
make goods. DBS providers may not use class distinctions to defeat the 
purpose of the lowest unit charge requirement. All classes must be fully 
disclosed and made available to candidates.
    (D) DBS providers may establish reasonable classes of preemptible 
with notice time so long as they clearly define all such classes, fully 
disclose them and make them available to candidates.
    (E) DBS providers may treat non preemptible and fixed position as 
distinct classes of time provided that they articulate clearly the 
differences between such classes, fully disclose them, and make them 
available to candidates.
    (F) DBS providers shall not establish a separate, premium priced 
class of time sold only to candidates. DBS providers may sell higher 
priced non preemptible or fixed time to candidates if such a class of 
time is made available on a bona fide basis to both candidates and 
commercial advertisers, and provided such class is not functionally 
equivalent to any lower priced class of time sold to commercial 
advertisers.
    (G) [Reserved]

[[Page 284]]

    (H) Lowest unit charge may be calculated on a weekly basis with 
respect to time that is sold on a weekly basis, such as rotations 
through particular programs or dayparts. DBS providers electing to 
calculate the lowest unit charge by such a method must include in that 
calculation all rates for all announcements scheduled in the rotation, 
including announcements aired under long term advertising contracts. DBS 
providers may implement rate increases during election periods only to 
the extent that such increases constitute ``ordinary business 
practices,'' such as seasonal program changes or changes in audience 
ratings.
    (I) DBS providers shall review their advertising records 
periodically throughout the election period to determine whether 
compliance with this section requires that candidates receive rebates or 
credits. Where necessary, DBS providers shall issue such rebates or 
credits promptly.
    (J) Unit rates charged as part of any package, whether individually 
negotiated or generally available to all advertisers, must be included 
in the lowest unit charge calculation for the same class and length of 
time in the same time period. A candidate cannot be required to purchase 
advertising in every program or daypart in a package as a condition for 
obtaining package unit rates.
    (K) DBS providers are not required to include non cash promotional 
merchandising incentives in lowest unit charge calculations; provided, 
however, that all such incentives must be offered to candidates as part 
of any purchases permitted by the system. Bonus spots, however, must be 
included in the calculation of the lowest unit charge calculation.
    (L) Make goods, defined as the rescheduling of preempted 
advertising, shall be provided to candidates prior to election day if a 
DBS provider has provided a time sensitive make good during the year 
preceding the pre election periods, respectively set forth in paragraph 
(c)(1)(i) of this section, to any commercial advertiser who purchased 
time in the same class.
    (M) DBS providers must disclose and make available to candidates any 
make good policies provided to commercial advertisers. If a DBS provider 
places a make good for any commercial advertiser or other candidate in a 
more valuable program or daypart, the value of such make good must be 
included in the calculation of the lowest unit charge for that program 
or daypart.
    (ii) At any time other than the respective periods set forth in 
paragraph (c)(1)(i) of this section, DBS providers may charge legally 
qualified candidates for public office no more than the charges made for 
comparable use of the facility by commercial advertisers. The rates, if 
any, charged all such candidates for the same office shall be uniform 
and shall not be rebated by any means, direct or indirect. A candidate 
shall be charged no more than the rate the DBS provider would charge for 
comparable commercial advertising. All discount privileges otherwise 
offered by a DBS provider to commercial advertisers must be disclosed 
and made available upon equal terms to all candidates for public office.
    (2) If a DBS provider permits a candidate to use its facilities, it 
shall make all discount privileges offered to commercial advertisers, 
including the lowest unit charges for each class and length of time in 
the same time period and all corresponding discount privileges, 
available on equal terms to all candidates. This duty includes an 
affirmative duty to disclose to candidates information about rates, 
terms, conditions and all value enhancing discount privileges offered to 
commercial advertisers, as provided herein. DBS providers may use 
reasonable discretion in making the disclosure; provided, however, that 
the disclosure includes, at a minimum, the following information:
    (i) A description and definition of each class of time available to 
commercial advertisers sufficiently complete enough to allow candidates 
to identify and understand what specific attributes differentiate each 
class;
    (ii) A description of the lowest unit charge and related privileges 
(such as priorities against preemption and make goods prior to specific 
deadlines) for each class of time offered to commercial advertisers;
    (iii) A description of the DBS provider's method of selling 
preemptible

time based upon advertiser demand, commonly known as the ``current 
selling level,'' with the stipulation that candidates will be able to 
purchase at these demand generated rates in the same manner as 
commercial advertisers;
    (iv) An approximation of the likelihood of preemption for each kind 
of preemptible time; and
    (v) An explanation of the DBS provider's sales practices, if any, 
that are based on audience delivery, with the stipulation that 
candidates will be able to purchase this kind of time, if available to 
commercial advertisers.
    (3) Once disclosure is made, DBS providers shall negotiate in good 
faith to actually sell time to candidates in accordance with the 
disclosure.
    (d) Political file. (1) Each DBS operator engaged in origination 
programming shall maintain, and make available for public inspection, a 
complete record of a request to purchase adverting time that:
    (i) Is made by or on behalf of a legally qualified candidate for 
public office; or
    (ii) Communicates a message relating to any political matter of 
national importance, including:
    (A) A legally qualified candidate;
    (B) Any election to Federal office; or
    (C) A national legislative issue of public importance.
    (2) A record maintained under this paragraph shall contain 
information regarding:
    (i) Whether the request to purchase advertising time is accepted or 
rejected by the DBS operator;
    (ii) The rate charged for the advertising time;
    (iii) The date and time on which the communication is aired;
    (iv) The class of time that is purchased;
    (v) The name of the candidate to which the communication refers and 
the office to which the candidate is seeking election, the election to 
which the communication refers, or the issue to which the communication 
refers (as applicable);
    (vi) In the case of a request made by, or on behalf of, a candidate, 
the name of the candidate, the authorized committee of the candidate, 
and the treasurer of such committee; and
    (vii) In the case of any other request, the name of the person 
purchasing the time, the name, address, and phone number of a contact 
person for such person, and a list of the chief executive officers or 
members of the executive committee or of the board of directors of such 
person.
    (3) When free time is provided for use by or on behalf of 
candidates, a record of the free time provided shall be placed in the 
political file.
    (4) All records required by this paragraph shall be placed in the 
online public file hosted by the Commission as soon as possible and 
shall be retained for a period of two years. As soon as possible means 
immediately absent unusual circumstances.
    (e) Commercial limits in children's programs. (1) No DBS provider 
shall air more than 10.5 minutes of commercial matter per hour during 
children's programming on weekends, or more that 12 minutes of 
commercial matter per hour on week days.
    (2) This rule shall not apply to programs aired on a broadcast 
television channel which the DBS provider passively carries, or to 
channels over which the DBS provider may not exercise editorial control, 
pursuant to 47 U.S.C. 335(b)(3).
    (3) DBS providers airing children's programming must maintain in the 
online file hosted by the Commission records sufficient to verify 
compliance with this rule. Such records must be maintained for a period 
sufficient to cover the limitations period specified in 47 U.S.C. 
503(b)(6)(B).

    Note 1 to paragraph (e): Commercial matter means airtime sold for 
purposes of selling a product or service.
    Note 2 to paragraph (e): For purposes of this section, children's 
programming refers to programs originally produced and broadcast 
primarily for an audience of children 12 years old and younger.

    (f) Carriage obligation for noncommercial programming--
    (1) Reservation requirement. DBS providers shall reserve four 
percent of their channel capacity exclusively for use by qualified 
programmers for noncommercial programming of an educational or 
informational nature.

[[Page 286]]

Channel capacity shall be determined annually by calculating, based on 
measurements taken on a quarterly basis, the average number of channels 
available for video programming on all satellites licensed to the 
provider during the previous year. DBS providers may use this reserved 
capacity for any purpose until such time as it is used for noncommercial 
educational or informational programming.
    (2) Qualified programmer. For purposes of these rules, a qualified 
programmer is:
    (i) A noncommercial educational broadcast station as defined in 
section 397(6) of the Communications Act of 1934, as amended,
    (ii) A public telecommunications entity as defined in section 
397(12) of the Communications Act of 1934, as amended,
    (iii) An accredited nonprofit educational institution or a 
governmental organization engaged in the formal education of enrolled 
students (A publicly supported educational institution must be 
accredited by the appropriate state department of education; a privately 
controlled educational institution must be accredited by the appropriate 
state department of education or the recognized regional and national 
accrediting organizations), or
    (iv) A nonprofit organization whose purposes are educational and 
include providing educational and instructional television material to 
such accredited institutions and governmental organizations.
    (v) Other noncommercial entities with an educational mission.
    (3) Editorial control. (i) A DBS operator will be required to make 
capacity available only to qualified programmers and may select among 
such programmers when demand exceeds the capacity of their reserved 
channels.
    (ii) A DBS operator may not require the programmers it selects to 
include particular programming on its channels.
    (iii) A DBS operator may not alter or censor the content of the 
programming provided by the qualified programmer using the channels 
reserved pursuant to this section.
    (4) Non-commercial channel limitation. A DBS operator cannot 
initially select a qualified programmer to fill more than one of its 
reserved channels except that, after all qualified entities that have 
sought access have been offered access on at least one channel, a 
provider may allocate additional channels to qualified programmers 
without having to make additional efforts to secure other qualified 
programmers.
    (5) Rates, terms and conditions. (i) In making the required reserved 
capacity available, DBS providers cannot charge rates that exceed costs 
that are directly related to making the capacity available to qualified 
programmers. Direct costs include only the cost of transmitting the 
signal to the uplink facility and uplinking the signal to the satellite.
    (ii) Rates for capacity reserved under paragraph (a) of this section 
shall not exceed 50 percent of the direct costs as defined in this 
section.
    (iii) Nothing in this section shall be construed to prohibit DBS 
providers from negotiating rates with qualified programmers that are 
less than 50 percent of direct costs or from paying qualified 
programmers for the use of their programming.
    (iv) DBS providers shall reserve discrete channels and offer these 
to qualifying programmers at consistent times to fulfill the reservation 
requirement described in these rules.
    (6) Public file. (i) In addition to the political file requirements 
in Sec.  25.701, each DBS provider shall maintain in the online file 
hosted by the Commission a complete and orderly record of:
    (A) Quarterly measurements of channel capacity and yearly average 
calculations on which it bases its four percent reservation, as well as 
its response to any capacity changes;
    (B) A record of entities to whom noncommercial capacity is being 
provided, the amount of capacity being provided to each entity, the 
conditions under which it is being provided and the rates, if any, being 
paid by the entity;
    (C) A record of entities that have requested capacity, disposition 
of those requests and reasons for the disposition.
    (D) Each satellite carrier shall, no later than July 31, 2020, 
provide an up-to-date email address for carriage election notice 
submissions and an up-to-

[[Page 287]]

date phone number for carriage-related questions. Each satellite carrier 
is responsible for the continuing accuracy and completeness of the 
information furnished. It must respond to questions from broadcasters as 
soon as is reasonably possible.
    (ii) All records required by paragraph (i) of this paragraph shall 
be placed in the online file hosted by the Commission as soon as 
possible and shall be retained for a period of two years.
    (iii) Each DBS provider must also place in the online file hosted by 
the Commission the records required to be placed in the public 
inspection file by Sec.  25.701(e) (commercial limits in children's 
programs) and by Sec.  25.601 and 47 CFR part 76, subpart E (equal 
employment opportunity requirements) and retain those records for the 
period required by those rules.
    (iv) Each DBS provider must provide a link to the online public 
inspection file hosted on the Commission's Web site from the home page 
of its own Web site, if the provider has a Web site, and provide on its 
Web site contact information for a representative who can assist any 
person with disabilities with issues related to the content of the 
public files. Each DBS provider also must include in the online public 
file hosted by the Commission the address of the provider's local public 
file, if the provider retains documents in the local public file that 
are not available in the Commission's online file, and the name, phone 
number, and email address of the provider's designated contact for 
questions about the public file.
    (7) Effective date. DBS providers are required to make channel 
capacity available pursuant to this section upon the effective date. 
Programming provided pursuant to this rule must be available to the 
public no later than six months after the effective date.

    Note to paragraph (i)(2): No 125 kHz channels are provided for 
channels in operation in this service. The 125 kHz channels previously 
associated with these channels have been reallocated to Channel G3 in 
the upper band segment.

    (3) [Reserved]
    (4) A temporary fixed broadband station may use any available 
broadband channel on a secondary basis, except that operation of 
temporary fixed broadband stations is not allowed within 56.3 km (35 
miles) of Canada.
    (5)(i) A point-to-point EBS station on the E and F-channel 
frequencies, may be involuntarily displaced by a BRS applicant or 
licensee, provided that suitable alternative spectrum is available and 
that the BRS entity bears the expenses of the migration. Suitability of 
spectrum will be determined on a case-by-base basis; at a minimum, the 
alternative spectrum must be licensable by broadband operators on a 
primary basis (although it need not be specifically allocated to the 
broadband service), and must provide a signal that is equivalent to the 
prior signal in picture quality and reliability, unless the broadband 
licensee will accept an inferior signal. Potential expansion of the BRS 
licensee may be considered in determining whether alternative available 
spectrum is suitable.
    (ii) If suitable alternative spectrum is located pursuant to 
paragraph (h)(6)(i) of this section, the initiating party must prepare 
and file the appropriate application for the new spectrum, and must 
simultaneously serve a copy of the application on the EBS licensee to be 
moved. The initiating party will be responsible for all costs connected 
with the migration, including purchasing, testing and installing new 
equipment, labor costs, reconfiguration of existing equipment, 
administrative costs, legal and engineering expenses necessary to 
prepare and file the migration application, and other reasonable 
documented costs. The initiating party must secure a bond or establish 
an escrow account to cover reasonable incremental increase in ongoing 
expenses that may fall upon the migrated licensee. The bond or escrow 
account should also account for the possibility that the initiating 
party subsequently becomes bankrupt. If it becomes necessary for the 
Commission to assess the sufficiency of a bond or escrow amount, it will 
take into account such factors as projected incremental increase in 
electricity or maintenance expenses, or relocation expenses, as relevant 
in each case.
    (iii) The EBS licensee to be moved will have a 60-day period in 
which to oppose the involuntary migration. The broadband party should 
state its opposition to the migration with specificity, including 
engineering and other challenges, and a comparison of the present site 
and the proposed new site. If involuntary migration is granted, the new 
facilities must be operational before the initiating party will be 
permitted to begin its new or modified operations. The migration must 
not disrupt the broadband licensee's provision of service, and the 
broadband licensee has the right to inspect the construction or 
installation work.
    (j) 2000-2020 MHz and 2180-2200 MHz bands. The following frequencies 
are available for licensing pursuant to this part in the 2000-2020 MHz

    (a) Single authorization. Authorization will be granted to provide 
any or a combination of the following services in a single license: 
common carrier, non-common carrier, private internal communications, and 
broadcast services. A licensee may render any kind of communications 
service consistent with the regulatory status in its license and with 
the Commission's rules applicable to that service. An applicant or 
licensee may submit a petition at any time requesting clarification of 
the regulatory status for which authorization is required to provide a 
specific communications service.
    (b) Designation of regulatory status in initial application. An 
applicant shall specify in its initial application if it is requesting 
authorization to provide common carrier, non-common carrier, private 
internal communications, or broadcast services, or a combination 
thereof.
    (c) Amendment of pending applications. The following rules apply to 
amendments of a pending application.
    (1) Any pending application may be amended to:
    (i) Change the carrier regulatory status requested, or
    (ii) Add to the pending request in order to obtain common carrier, 
non-common carrier, private internal communications, or broadcast 
services status, or a combination thereof, in a single license.
    (2) Amendments to change, or add to, the carrier regulatory status 
in a pending application are minor amendments filed under Sec.  1.927 of 
this chapter.
    (d) Modification of license. The following rules apply to amendments 
of a license.
    (1) A licensee may modify a license to:
    (i) Change the regulatory status authorized, or
    (ii) Add to the status authorized in order to obtain a combination 
of services of different regulatory status in a single license.
    (2) Applications to change, or add to, the carrier status in a 
license are modifications not requiring prior Commission authorization. 
The licensee must notify the Commission within 30 days of the change. If 
the change results in the discontinuance, reduction, or impairment of an 
existing service, the licensee is subject to the provisions of Sec.  
27.66.

Sec.  27.14  Construction requirements.

    (a) AWS and WCS licensees, with the exception of WCS licensees 
holding authorizations for the 600 MHz band, Block A in the 698-704 MHz 
and 728-734 MHz bands, Block B in the 704-710 MHz and 734-740 MHz bands, 
Block E in the 722-728 MHz band, Block C, C1, or C2 in the 746-757 MHz 
and 776-787 MHz bands, Block A in the 2305-2310 MHz and 2350-2355 MHz 
bands, Block B in the 2310-2315 MHz and 2355-2360 MHz bands, Block C in 
the 2315-2320 MHz band, Block D in the 2345-2350 MHz band, in the 3450-
3550 MHz band, and in the 3700-3980 MHz band, and with the exception of 
licensees holding AWS authorizations in the 1915-1920 MHz and 1995-2000 
MHz bands, the 2000-2020 MHz and 2180-2200 MHz bands, or 1695-1710 MHz, 
1755-1780 MHz and 2155-2180 MHz bands, must, as a performance 
requirement, make a showing of ``substantial service'' in their license 
area within the prescribed license term set forth in Sec.  27.13. 
``Substantial service'' is defined as service which is sound, favorable 
and substantially above a level of mediocre service which just might 
minimally warrant renewal. Failure by any licensee to meet this 
requirement will result in forfeiture of the license and the licensee 
will be ineligible to regain it.
    (b)-(f) [Reserved]
    (g) WCS licensees holding EA authorizations for Block A in the 698-
704 MHz and 728-734 MHz bands, cellular market authorizations for Block 
B in the 704-710 MHz and 734-740 MHz bands, or EA authorizations for 
Block E in the 722-728 MHz band, if the results of the first auction in 
which licenses for such authorizations are offered satisfy the reserve 
price for the applicable block, shall provide signal coverage and offer 
service over at least 35 percent of the geographic area of each of their 
license authorizations no later than June 13, 2013 (or within four years 
of initial license grant if the initial authorization in a market is 
granted after June 13, 2009), and shall provide such service over at 
least 70 percent of the geographic area of each of these authorizations 
by the end of the license term. In applying these geographic benchmarks, 
licensees are not required to include land owned or administered by 
government as a part of the relevant service area. Licensees may count 
covered government land for purposes of meeting

[[Page 329]]

their geographic construction benchmark, but are required to add the 
covered government land to the total geographic area used for 
measurement purposes. Licensees are required to include those populated 
lands held by tribal governments and those held by the Federal 
Government in trust or for the benefit of a recognized tribe.
    (1) If an EA or CMA licensee holding an authorization in these 
particular blocks fails to provide signal coverage and offer service 
over at least 35 percent of the geographic area of its license 
authorization by no later than June 13, 2013 (or within four years of 
initial license grant, if the initial authorization in a market is 
granted after June 13, 2009), the term of that license authorization 
will be reduced by two years and such licensee may be subject to 
enforcement action, including forfeitures. In addition, an EA or CMA 
licensee that provides signal coverage and offers service at a level 
that is below this interim benchmark may lose authority to operate in 
part of the remaining unserved areas of the license.
    (2) If any such EA or CMA licensee fails to provide signal coverage 
and offer service to at least 70 percent of the geographic area of its 
license authorization by the end of the license term, that licensee's 
authorization will terminate automatically without Commission action for 
those geographic portions of its license in which the licensee is not 
providing service, and those unserved areas will become available for 
reassignment by the Commission. Such licensee may also be subject to 
enforcement action, including forfeitures. In addition, an EA or CMA 
licensee that provides signal coverage and offers service at a level 
that is below this end-of-term benchmark may be subject to license 
termination. In the event that a licensee's authority to operate in a 
license area terminates automatically without Commission action, such 
areas will become available for reassignment pursuant to the procedures 
in paragraph (j) of this section.
    (3) For licenses under paragraph (g) of this section, the geographic 
service area to be made available for reassignment must include a 
contiguous area of at least 130 square kilometers (50 square miles), and 
areas smaller than a contiguous area of at least 130 square kilometers 
(50 square miles) will not be deemed unserved.
    (h) WCS licensees holding REAG authorizations for Block C in the 
746-757 MHz and 776-787 MHz bands or REAG authorizations for Block C2 in 
the 752-757 MHz and 782-787 MHz bands shall provide signal coverage and 
offer service over at least 40 percent of the population in each EA 
comprising the REAG license area no later than June 13, 2013 (or within 
four years of initial license grant, if the initial authorization in a 
market is granted after June 13, 2009), and shall provide such service 
over at least 75 percent of the population of each of these EAs by the 
end of the license term. For purposes of compliance with this 
requirement, licensees should determine population based on the most 
recently available U.S. Census Data.
    (1) If a licensee holding a Block C authorization fails to provide 
signal coverage and offer service over at least 40 percent of the 
population in each EA comprising the REAG license area by no later than 
June 13, 2013 (or within four years of initial license grant if the 
initial authorization in a market is granted after June 13, 2009), the 
term of the license authorization will be reduced by two years and such 
licensee may be subject to enforcement action, including forfeitures. In 
addition, a licensee that provides signal coverage and offers service at 
a level that is below this interim benchmark may lose authority to 
operate in part of the remaining unserved areas of the license.
    (2) If a licensee holding a Block C authorization fails to provide 
signal coverage and offer service over at least 75 percent of the 
population in any EA comprising the REAG license area by the end of the 
license term, for each such EA that licensee's authorization will 
terminate automatically without Commission action for those geographic 
portions of its license in which the licensee is not providing service. 
Such licensee may also be subject to

[[Page 330]]

enforcement action, including forfeitures. In the event that a 
licensee's authority to operate in a license area terminates 
automatically without Commission action, such areas will become 
available for reassignment pursuant to the procedures in paragraph (j) 
of this section. In addition, a REAG licensee that provides signal 
coverage and offers service at a level that is below this end-of-term 
benchmark within any EA may be subject to license termination within 
that EA.
    (3) For licenses under paragraph (h), the geographic service area to 
be made available for reassignment must include a contiguous area of at 
least 130 square kilometers (50 square miles), and areas smaller than a 
contiguous area of at least 130 square kilometers (50 square miles) will 
not be deemed unserved.
    (i) WCS licensees holding EA authorizations for Block A in the 698-
704 MHz and 728-734 MHz bands, cellular market authorizations for Block 
B in the 704-710 MHz and 734-740 MHz bands, or EA authorizations for 
Block E in the 722-728 MHz band, if the results of the first auction in 
which licenses for such authorizations in Blocks A, B, and E are offered 
do not satisfy the reserve price for the applicable block, as well as EA 
authorizations for Block C1 in the 746-752 MHz and 776-782 MHz bands, 
are subject to the following:
    (1) If a licensee holding a cellular market area or EA authorization 
subject to this paragraph (i) fails to provide signal coverage and offer 
service over at least 40 percent of the population in its license area 
by no later than June 13, 2013 (or within four years of initial license 
grant, if the initial authorization in a market is granted after June 
13, 2009), the term of that license authorization will be reduced by two 
years and such licensee may be subject to enforcement action, including 
forfeitures. In addition, such licensee that provides signal coverage 
and offers service at a level that is below this interim benchmark may 
lose authority to operate in part of the remaining unserved areas of the 
license. For purposes of compliance with this requirement, licensees 
should determine population based on the most recently available U.S. 
Census Data.
    (2) If a licensee holding a cellular market area or EA authorization 
subject to this paragraph (i) fails to provide signal coverage and offer 
service over at least 75 percent of the population in its license area 
by the end of the license term, that licensee's authorization will 
terminate automatically without Commission action for those geographic 
portions of its license in which the licensee is not providing service, 
and those unserved areas will become available for reassignment by the 
Commission. Such licensee may also be subject to enforcement action, 
including forfeitures. In the event that a licensee's authority to 
operate in a license area terminates automatically without Commission 
action, such areas will become available for reassignment pursuant to 
the procedures in paragraph (j) of this section. In addition, such a 
licensee that provides signal coverage and offers service at a level 
that is below this end-of-term benchmark may be subject to license 
termination. For purposes of compliance with this requirement, licensees 
should determine population based on the most recently available U.S. 
Census Data.
    (3) For licenses under paragraph (i), the geographic service area to 
be made available for reassignment must include a contiguous area of at 
least 130 square kilometers (50 square miles), and areas smaller than a 
contiguous area of at least 130 square kilometers (50 square miles) will 
not be deemed unserved.
    (j) In the event that a licensee's authority to operate in a license 
area terminates automatically under paragraphs (g), (h), or (i) of this 
section, such areas will become available for reassignment pursuant to 
the following procedures:
    (1) The Wireless Telecommunications Bureau is delegated authority to 
announce by public notice that these license areas will be made 
available and establish a 30-day window during which third parties may 
file license applications to serve these areas. During this 30-day 
period, licensees that had their authority to operate terminate 
automatically for unserved areas may not file applications to provide 
service to these areas. Applications filed by third

[[Page 331]]

parties that propose areas overlapping with other applications will be 
deemed mutually exclusive, and will be resolved through an auction. The 
Wireless Telecommunications Bureau, by public notice, may specify a 
limited period before the filing of short-form applications (FCC Form 
175) during which applicants may enter into a settlement to resolve 
their mutual exclusivity, subject to the provisions of Sec.  1.935 of 
this chapter.
    (2) Following this 30-day period, the original licensee and third 
parties can file license applications for remaining unserved areas where 
licenses have not been issued or for which there are no pending 
applications. If the original licensee or a third party files an 
application, that application will be placed on public notice for 30 
days. If no mutually exclusive application is filed, the application 
will be granted, provided that a grant is found to be in the public 
interest. If a mutually exclusive application is filed, it will be 
resolved through an auction. The Wireless Telecommunications Bureau, by 
public notice, may specify a limited period before the filing of short-
form applications (FCC Form 175) during which applicants may enter into 
a settlement to resolve their mutual exclusivity, subject to the 
provisions of Sec.  1.935 of this chapter.
    (3) The licensee will have one year from the date the new license is 
issued to complete its construction and provide signal coverage and 
offer service over 100 percent of the geographic area of the new license 
area. If the licensee fails to meet this construction requirement, its 
license will automatically terminate without Commission action and it 
will not be eligible to apply to provide service to this area at any 
future date.
    (k) Licensees holding WCS or AWS authorizations in the spectrum 
blocks enumerated in paragraphs (g), (h), (i), (q), (r), (s), (t), (v), 
and (w) of this section, including any licensee that obtained its 
license pursuant to the procedures set forth in paragraph (j) of this 
section, shall demonstrate compliance with performance requirements by 
filing a construction notification with the Commission, within 15 days 
of the expiration of the applicable benchmark, in accordance with the 
provisions set forth in Sec.  1.946(d) of this chapter. The licensee 
must certify whether it has met the applicable performance requirements. 
The licensee must file a description and certification of the areas for 
which it is providing service. The construction notifications must 
include electronic coverage maps, supporting technical documentation and 
any other information as the Wireless Telecommunications Bureau may 
prescribe by public notice.
    (l) WCS licensees holding authorizations in the spectrum blocks 
enumerated in paragraphs (g), (h), or (i) of this section, excluding any 
licensee that obtained its license pursuant to the procedures set forth 
in subsection (j) of this section, shall file reports with the 
Commission that provide the Commission, at a minimum, with information 
concerning the status of their efforts to meet the performance 
requirements applicable to their authorizations in such spectrum blocks 
and the manner in which that spectrum is being utilized. The information 
to be reported will include the date the license term commenced, a 
description of the steps the licensee has taken toward meeting its 
construction obligations in a timely manner, including the technology or 
technologies and service(s) being provided, and the areas within the 
license area in which those services are available. Each of these 
licensees shall file its first report with the Commission no later than 
June 13, 2011 and no sooner than 30 days prior to this date. Each 
licensee that meets its interim benchmarks shall file a second report 
with the Commission no later than June 13, 2016 and no sooner than 30 
days prior to this date. Each licensee that does not meet its interim 
benchmark shall file this second report no later than on June 13, 2015 
and no sooner than 30 days prior to this date.
    (m)-(n) [Reserved]
    (o) With respect to initial BRS licenses issued on or after November 
6, 2009, the licensee must make a showing of substantial service within 
four years from the date of issue of the license. With respect to EBS 
licenses issued after October 25, 2019, the licensee must comply with 
paragraph (u) of this section. ``Substantial service'' is defined

[[Page 332]]

as service which is sound, favorable, and substantially above a level of 
mediocre service which just might minimally warrant renewal. Substantial 
service for BRS and EBS licensees is satisfied if a licensee meets the 
requirements of paragraph (o)(1), (2), or (3) of this section. If a 
licensee has not met the requirements of paragraph (o)(1), (2), or (3) 
of this section, then demonstration of substantial service shall proceed 
on a case-by-case basis. Except as provided in paragraphs (o)(4) and (5) 
of this section, all substantial service determinations will be made on 
a license-by-license basis. Failure by any licensee to demonstrate 
substantial service will result in forfeiture of the license and the 
licensee will be ineligible to regain it.
    (1) A BRS or EBS licensee has provided ``substantial service'' by:
    (i) Constructing six permanent links per one million people for 
licensees providing fixed point-to-point services;
    (ii) Providing coverage of at least 30 percent of the population of 
the licensed area for licensees providing mobile services or fixed 
point-to-multipoint services;
    (iii) Providing service to ``rural areas'' (a county (or equivalent) 
with a population density of 100 persons per square mile or less, based 
upon the most recently available Census data) and areas with limited 
access to telecommunications services:
    (A) For mobile service, where coverage is provided to at least 75% 
of the geographic area of at least 30% of the rural areas within its 
service area; or
    (B) for fixed service, where the BRS or EBS licensee has constructed 
at least one end of a permanent link in at least 30% of the rural areas 
within its licensed area.
    (iv) Providing specialized or technologically sophisticated service 
that does not require a high level of coverage to benefit consumers; or
    (v) Providing service to niche markets or areas outside the areas 
served by other licensees.
    (2) An EBS license initially issued prior to October 25, 2019 has 
provided ``substantial service'' when:
    (i) The EBS licensee is using its spectrum (or spectrum to which the 
EBS licensee's educational services are shifted) to provide educational 
services within the EBS licensee's GSA;
    (ii) the EBS licensee's license is actually being used to serve the 
educational mission of one or more accredited public or private schools, 
colleges or universities providing formal educational and cultural 
development to enrolled students; or
    (iii) The level of service provided by the EBS licensee meets or 
exceeds the minimum usage requirements specified in Sec.  27.1214 
contained in the edition of 47 CFR parts 20 through 39, revised as of 
October 1, 2017.
    (3) An EBS or BRS licensee may be deemed to provide substantial 
service through a leasing arrangement if the lessee is providing 
substantial service under paragraph (o)(1) of this section.
    (4) If the GSA of a licensee is less than 1924 square miles in size, 
and there is an overlapping co-channel station licensed or leased by the 
licensee or its affiliate, substantial service may be demonstrated by 
meeting the requirements of paragraph (o)(1) or (o)(2) of this section 
with respect to the combined GSAs of both stations.
    (5) If the GSA of a BTA authorization holder, is less than one-half 
of the area within the BTA for every BRS channel, substantial service 
may be demonstrated for the licenses in question by meeting the 
requirements of paragraph (o)(1) or (o)(2) of this section with respect 
to the combined GSAs of the BTA authorization holder, together with any 
incumbent authorizations licensed or leased by the licensee or its 
affiliates.
    (p) This section enumerates performance requirements for licensees 
holding authorizations for Block A in the 2305-2310 MHz and 2350-2355 
MHz bands, Block B in the 2310-2315 MHz and 2355-2360 MHz bands, Block C 
in the 2315-2320 MHz band, and Block D in the 2345-2350 MHz band.
    (1) For mobile and point-to-multipoint systems in Blocks A and B, 
and point-to-multipoint systems in Blocks C and D, a licensee must 
provide reliable signal coverage and offer service to at least 40 
percent of the license area's population by March 13, 2017, and to at 
least 75 percent of the license area's population by September 13, 2019. 
If, when filing the construction

[[Page 333]]

notification required under Sec.  1.946(d) of this chapter, a WCS 
licensee demonstrates that 25 percent or more of the license area's 
population for Block A, B or D is within a coordination zone as defined 
by Sec.  27.73(a) of the rules, the foregoing population benchmarks are 
reduced to 25 and 50 percent, respectively. The percentage of a license 
area's population within a coordination zone equals the sum of the 
Census Block Centroid Populations within the area, divided by the 
license area's total population.
    (2) For point-to-point fixed systems, except those deployed in the 
Gulf of Mexico license area, a licensee must construct and operate a 
minimum of 15 point-to-point links per million persons (one link per 
67,000 persons) in a license area by March 13, 2017, and 30 point-to-
point links per million persons (one link per 33,500 persons) in a 
licensed area by September 13, 2019. The exact link requirement is 
calculated by dividing a license area's total population by 67,000 and 
33,500 for the respective milestones, and then rounding upwards to the 
next whole number. For a link to be counted towards these benchmarks, 
both of its endpoints must be located in the license area. If only one 
endpoint of a link is located in a license area, it can be counted as a 
one- half link towards the benchmarks.
    (3) For point-to-point fixed systems deployed on any spectrum block 
in the Gulf of Mexico license area, a licensee must construct and 
operate a minimum of 15 point-to-point links by March 13, 2017, and a 
minimum of 15 point-to-point links by September 13, 2019.
    (4) Under paragraph (p)(2) and (p)(3) of this section, each fixed 
link must provide a minimum bit rate, in bits per second, equal to or 
greater than the bandwidth specified by the emission designator in Hertz 
(e.g., equipment transmitting at a 5 Mb/s rate must not require a 
bandwidth of greater than 5 MHz).
    (5) If an initial authorization for a license area is granted after 
March 13, 2013, then the applicable benchmarks in paragraphs (p)(1), (2) 
and (3) of this section must be met within 48 and 78 months, 
respectively, of the initial authorization grant date.
    (6) Licensees must use the most recently available U.S. Census Data 
at the time of measurement to meet these performance requirements.
    (7) Licensees must certify compliance with the applicable 
performance requirements by filing a construction notification with the 
Commission, within 15 days of the expiration of the relevant performance 
milestone, pursuant to Sec.  1.946(d) of this chapter. Each construction 
notification must include electronic coverage maps, supporting technical 
documentation, and any other information as the Wireless 
Telecommunications Bureau may prescribe by public notice. Electronic 
coverage maps must accurately depict the boundaries of each license area 
(Regional Economic Area Grouping, REAG, or Major Economic Area, MEA) in 
the licensee's service territory. Further, REAG maps must depict MEA 
boundaries and MEA maps must depict Economic Area boundaries. If a 
licensee does not provide reliable signal coverage to an entire license 
area, its map must accurately depict the boundaries of the area or areas 
within each license area not being served. Each licensee also must file 
supporting documentation certifying the type of service it is providing 
for each REAG or MEA within its service territory and the type of 
technology used to provide such service. Supporting documentation must 
include the assumptions used to create the coverage maps, including the 
propagation model and the signal strength necessary to provide reliable 
service with the licensee's technology.
    (8) If a licensee fails to meet any applicable performance 
requirement, its authorization will terminate automatically without 
further Commission action as of the applicable performance milestone and 
the licensee will be ineligible to regain it.
    (q) The following provisions apply to any licensee holding an AWS 
authorization in the 2000-2020 MHz and 2180-2200 MHz bands (an ``AWS-4 
licensee''):
    (1) An AWS-4 licensee shall provide terrestrial signal coverage and 
offer terrestrial service within four (4) years from the date of the 
license to at least

[[Page 334]]

forty (40) percent of the total population in the aggregate service 
areas that it has licensed in the 2000-2020 MHz and 2180-2200 MHz bands 
(``AWS-4 Interim Buildout Requirement''). For purposes of this subpart, 
a licensee's total population shall be calculated by summing the 
population of each license area that a licensee holds in the 2000-2020 
MHz and 2180-2200 MHz bands; and
    (2) An AWS-4 licensee shall provide terrestrial signal coverage and 
offer terrestrial service within seven (7) years from the date of the 
license to at least seventy (70) percent of the population in each of 
its license areas in the 2000-2020 MHz and 2180-2200 MHz bands (``AWS-4 
Final Buildout Requirement'').
    (3) If any AWS-4 licensee fails to establish that it meets the AWS-4 
Interim Buildout Requirement, the AWS-4 Final Buildout requirement shall 
be accelerated by one year from (seven to six years).
    (4) If any AWS-4 licensee fails to establish that it meets the AWS-4 
Final Buildout Requirement in any of its license areas in the 2000-2020 
MHz and 2180-2200 MHz bands, its authorization for each license area in 
which it fails to meet the requirement shall terminate automatically 
without Commission action. To the extent that the AWS-4 licensee also 
holds the 2 GHz MSS rights for the affected license area, failure to 
meet the AWS-4 Final Buildout Requirement in an EA shall also result in 
the MSS protection rule in Sec.  27.1136 no longer applying in that 
license area.
    (5) To demonstrate compliance with these performance requirements, 
licensees shall use the most recently available U.S. Census Data at the 
time of measurement and shall base their measurements of population 
served on areas no larger than the Census Tract level. The population 
within a specific Census Tract (or other acceptable identifier) will 
only be deemed served by the licensee if it provides signal coverage to 
and offers service within the specific Census Tract (or other acceptable 
identifier). To the extent the Census Tract (or other acceptable 
identifier) extends beyond the boundaries of a license area, a licensee 
with authorizations for such areas may only include the population 
within the Census Tract (or other acceptable identifier) towards meeting 
the performance requirement of a single, individual license.
    (6) Failure by any AWS-4 licensee to meet the AWS-4 Final Buildout 
Requirement in paragraph (q)(4) of this section will result in 
forfeiture of the license and the licensee will be ineligible to regain 
it.
    (r) The following provisions apply to any licensee holding an AWS 
authorization in the 1915-1920 MHz and 1995-2000 MHz bands:
    (1) A licensee shall provide signal coverage and offer service 
within four (4) years from the date of the initial license to at least 
forty (40) percent of the population in each of its licensed areas 
(``Interim Buildout Requirement'').
    (2) A licensee shall provide signal coverage and offer service 
within ten (10) years from the date of the initial license to at least 
seventy-five (75) percent of the population in each of its licensed 
areas (``Final Buildout Requirement'').
    (3) If a licensee fails to establish that it meets the Interim 
Buildout Requirement for a particular licensed area, then the Final 
Buildout Requirement (in this paragraph (r)) and the license term (as 
set forth in Sec.  27.13(j)) for each license area in which it fails to 
meet the Interim Buildout Requirement shall be accelerated by two years 
(from ten to eight years).
    (4) If a licensee fails to establish that it meets the Final 
Buildout Requirement for a particular licensed area, its authorization 
for each license area in which it fails to meet the Final Buildout 
Requirement shall terminate automatically without Commission action and 
the licensee will be ineligible to regain it if the Commission makes the 
license available at a later date.
    (5) To demonstrate compliance with these performance requirements, 
licensees shall use the most recently available U.S. Census Data at the 
time of measurement and shall base their measurements of population 
served on areas no larger than the Census Tract level. The population 
within a specific Census Tract (or other acceptable identifier) will 
only be deemed served by

[[Page 335]]

the licensee if it provides signal coverage to and offers service within 
the specific Census Tract (or other acceptable identifier). To the 
extent the Census Tract (or other acceptable identifier) extends beyond 
the boundaries of a license area, a licensee with authorizations for 
such areas may only include the population within the Census Tract (or 
other acceptable identifier) towards meeting the performance requirement 
of a single, individual license.
    (s) The following provisions apply to any licensee holding an AWS 
authorization in the 1695-1710 MHz, 1755-1780 MHz, and 2155-2180 MHz 
bands:
    (1) A licensee shall provide reliable signal coverage and offer 
service within six (6) years from the date of the initial license to at 
least forty (40) percent of the population in each of its licensed areas 
(``Interim Buildout Requirement'').
    (2) A licensee shall provide reliable signal coverage and offer 
service within twelve (12) years from the date of the initial license to 
at least seventy-five (75) percent of the population in each of its 
licensed areas (``Final Buildout Requirement'').
    (3) If a licensee fails to establish that it meets the Interim 
Buildout Requirement for a particular licensed area, then the Final 
Buildout Requirement (in this paragraph (s)) and the AWS license term 
(as set forth in Sec.  27.13(k)) for each license area in which it fails 
to meet the Interim Buildout Requirement shall be accelerated by two (2) 
years (from twelve (12) to ten (10) years).
    (4) If a licensee fails to establish that it meets the Final 
Buildout Requirement for a particular licensed area, its authorization 
for each license area in which it fails to meet the Final Buildout 
Requirement shall terminate automatically without Commission action and 
the licensee will be ineligible to regain it if the Commission makes the 
license available at a later date.
    (5) To demonstrate compliance with these performance requirements, 
licensees shall use the most recently available U.S. Census Data at the 
time of measurement and shall base their measurements of population 
served on areas no larger than the Census Tract level. The population 
within a specific Census Tract (or other acceptable identifier) will be 
deemed served by the licensee only if it provides signal coverage to and 
offers service within the specific Census Tract (or other acceptable 
identifier). To the extent the Census Tract (or other acceptable 
identifier) extends beyond the boundaries of a license area, a licensee 
with authorizations for such areas may include only the population 
within the Census Tract (or other acceptable identifier) towards meeting 
the performance requirement of a single, individual license. For the 
Gulf of Mexico license area, the licensee shall demonstrate compliance 
with these performance requirements, using off-shore platforms, 
including production, manifold, compression, pumping and valving 
platforms as a proxy for population in the Gulf of Mexico.
    (t) The following provisions apply to any licensee holding an 
authorization in the 600 MHz band:
    (1) A licensee shall provide reliable signal coverage and offer 
service within six (6) years from the date of the initial license to at 
least forty (40) percent of the population in each of its license areas 
(``Interim Buildout Requirement'').
    (2) A licensee shall provide reliable signal coverage and offer 
service within twelve (12) years from the date of the initial license to 
at least seventy-five (75) percent of the population in each of its 
license areas (``Final Buildout Requirement'').
    (3) If a licensee fails to establish that it meets the Interim 
Buildout Requirement for a particular licensed area, then the Final 
Buildout Requirement (in this paragraph (t)) and the license term (as 
set forth in Sec.  27.13(l)) for each license area in which it fails to 
meet the Interim Buildout Requirement shall be accelerated by two (2) 
years (from twelve (12) to ten (10) years).
    (4) If a licensee fails to establish that it meets the Final 
Buildout Requirement for a particular license area, its authorization 
for each license area in which it fails to meet the Final Buildout 
Requirement shall terminate automatically without Commission action,

[[Page 336]]

and the licensee will be ineligible to regain it if the Commission makes 
the license available at a later date.
    (5) To demonstrate compliance with these performance requirements, 
licensees shall use the most recently available decennial U.S. Census 
Data at the time of measurement and shall base their measurements of 
population served on areas no larger than the Census Tract level. The 
population within a specific Census Tract (or other acceptable 
identifier) will be deemed served by the licensee only if it provides 
reliable signal coverage to and offers service within the specific 
Census Tract (or other acceptable identifier). To the extent the Census 
Tract (or other acceptable identifier) extends beyond the boundaries of 
a license area, a licensee with authorizations for such areas may 
include only the population within the Census Tract (or other acceptable 
identifier) towards meeting the performance requirement of a single, 
individual license. For the Gulf of Mexico license area, the licensee 
shall demonstrate compliance with these performance requirements, using 
off-shore platforms, including production, manifold, compression, 
pumping and valving platforms as a proxy for population in the Gulf of 
Mexico.
    (u) This section enumerates performance requirements for EBS 
licenses initially issued after October 25, 2019. Licensees shall 
demonstrate compliance with performance requirements by filing a 
construction notification with the Commission, within 15 days of the 
expiration of the applicable benchmark, in accordance with the 
provisions set forth in Sec.  1.946(d) of this chapter.
    (1) All EBS licenses initially issued after October 25, 2019, must 
demonstrate compliance with the performance requirements described in 
this paragraph (u). All equipment used to demonstrate compliance must be 
in use and actually providing service, either for internal use or to 
unaffiliated customers, as of the interim deadline or final deadline, 
whichever is applicable.
    (2) Except for licensees with licenses applied for in the Tribal 
Priority Window, licensees providing mobile or point-to-multipoint 
service must demonstrate reliable signal coverage of 50% of the 
population of the geographic service area within four years of initial 
license grant, and 80% of the population of the geographic service area 
within eight years of initial license grant.
    (3) Except for licensees with licenses applied for in the Tribal 
Priority Window, licensees providing fixed point-to-point service must 
demonstrate operation of one link for each 50,000 persons in the 
geographic service area within four years of initial license grant, and 
one link for each 25,000 persons in the geographic service area within 
eight years of initial license grant.
    (4) Licensees with licenses applied for in the Tribal Priority 
Window must make an interim showing under paragraph (u)(2) or (3) of 
this section within two years of initial license grant. Licensees with 
licenses applied for in the Tribal Priority Window must make a final 
showing under paragraph (u)(2) or (3) of this section within five years 
of initial license grant.
    (5) If an EBS licensee (other than the licensee of a license issued 
pursuant to the Tribal Priority Window) fails to meet interim 
performance requirements described in paragraph (u)(2) or (3) of this 
section, the deadline for that authorization to meet its final 
performance requirement will be advanced by two years. If an EBS 
licensee of a license issued pursuant to the Tribal Priority Window 
fails to meet interim performance requirements described in paragraph 
(u)(2) or (3) of this section, the deadline for that authorization to 
meet its final performance requirement will be advanced by one year. If 
an EBS licensee fails to meet its final performance requirement, its 
license shall automatically terminate without specific Commission 
action.
    (v) The following provisions apply to any licensee holding an 
authorization in the 3700-3980 MHz band:
    (1) Licensees relying on mobile or point-to-multipoint service shall 
provide reliable signal coverage and offer service within eight (8) 
years from the date of the initial license to at least forty-five (45) 
percent of the population in each of its license areas (``First Buildout 
Requirement''). Licensee shall provide reliable signal coverage and 
offer service within twelve (12)

[[Page 337]]

years from the date of the initial license to at least eighty (80) 
percent of the population in each of its license areas (``Second 
Buildout Requirement''). Licensees relying on point-to-point service 
shall demonstrate within eight years of the license issue date that they 
have four links operating and providing service to customers or for 
internal use if the population within the license area is equal to or 
less than 268,000 and, if the population is greater than 268,000, that 
they have at least one link in operation and providing service to 
customers, or for internal use, per every 67,000 persons within a 
license area (``First Buildout Requirement''). Licensees relying on 
point-to-point service shall demonstrate within 12 years of the license 
issue date that they have eight links operating and providing service to 
customers or for internal use if the population within the license area 
is equal to or less than 268,000 and, if the population within the 
license area is greater than 268,000, shall demonstrate they are 
providing service and have at least two links in operation per every 
67,000 persons within a license area (``Second Buildout Requirement'').
    (2) In the alternative, a licensee offering Internet of Things-type 
services shall provide geographic area coverage within eight (8) years 
from the date of the initial license to thirty-five (35) percent of the 
license (``First Buildout Requirement''). A licensee offering Internet 
of Things-type services shall provide geographic area coverage within 
twelve (12) years from the date of the initial license to sixty-five 
(65) percent of the license (``Second Buildout Requirement'').
    (3) If a licensee fails to establish that it meets the First 
Buildout Requirement for a particular license area, the licensee's 
Second Buildout Requirement deadline and license term will be reduced by 
two years. If a licensee fails to establish that it meets the Second 
Buildout Requirement for a particular license area, its authorization 
for each license area in which it fails to meet the Second Buildout 
Requirement shall terminate automatically without Commission action, and 
the licensee will be ineligible to regain it if the Commission makes the 
license available at a later date.
    (4) To demonstrate compliance with these performance requirements, 
licensees shall use the most recently available decennial U.S. Census 
Data at the time of measurement and shall base their measurements of 
population or geographic area served on areas no larger than the Census 
Tract level. The population or area within a specific Census Tract (or 
other acceptable identifier) will be deemed served by the licensee only 
if it provides reliable signal coverage to and offers service within the 
specific Census Tract (or other acceptable identifier). To the extent 
the Census Tract (or other acceptable identifier) extends beyond the 
boundaries of a license area, a licensee with authorizations for such 
areas may include only the population or geographic area within the 
Census Tract (or other acceptable identifier) towards meeting the 
performance requirement of a single, individual license. If a licensee 
does not provide reliable signal coverage to an entire license area, the 
license must provide a map that accurately depicts the boundaries of the 
area or areas within each license area not being served. Each licensee 
also must file supporting documentation certifying the type of service 
it is providing for each licensed area within its service territory and 
the type of technology used to provide such service. Supporting 
documentation must include the assumptions used to create the coverage 
maps, including the propagation model and the signal strength necessary 
to provide reliable service with the licensee's technology.
    (w) The following provisions apply to any licensee holding an 
authorization in the 3450-3550 MHz band:
    (1) Performance requirements. Licensees in the 3.45 GHz Service must 
meet the following benchmarks, based on the type of service they 
provide.
    (i) Mobile/point-to-multipoint service. Licensees relying on mobile 
or point-to-multipoint service shall provide reliable signal coverage 
and offer service within four (4) years from the date of the initial 
license to at least forty-five (45) percent of the population in each of 
its license areas (``First Performance Benchmark''). Licensees shall 
provide

[[Page 338]]

reliable signal coverage and offer service within eight (8) years from 
the date of the initial license to at least eighty (80) percent of the 
population in each of its license areas (``Second Performance 
Benchmark'').
    (ii) Point-to-point service. Licensees relying on point-to-point 
service shall demonstrate within four (4) years of the license issue 
date that, if the population within the license area is equal to or less 
than 268,000, they have four links operating and either provide service 
to customers or for internal use. If the population is greater than 
268,000, they shall demonstrate they have at least one link in operation 
and either provide service to customers or for internal use per every 
67,000 persons within a license area (``First Performance Benchmark''). 
Licensees shall demonstrate within eight (8) years of the license issue 
date that, if the population within license area is equal to or less 
than 268,000, they have eight links operating and either provide service 
to customers or for internal use. If the population within the license 
area is greater than 268,000, they shall demonstrate they have at least 
two links in operation and either provide service to customers or for 
internal use per every 67,000 persons within a license area (``Second 
Performance Benchmark'').
    (iii) Internet of Things service. Licensees offering Internet of 
Things-type services shall provide geographic area coverage within four 
(4) years from the date of the initial license to thirty-five (35) 
percent of the license (``First Performance Benchmark''). Licensees 
shall provide geographic area coverage within eight (8) years from the 
date of the initial license to sixty-five (65) percent of the license 
(``Second Performance Benchmark'').
    (2) Failure to meet performance requirements. If a licensee fails to 
establish that it meets the First Performance Benchmark for a particular 
license area in paragraph (w)(1) of this section, the licensee's Second 
Performance Benchmark deadline and license term in paragraph (w)(1) of 
this section will be reduced by one year. If a licensee fails to 
establish that it meets the Second Performance Benchmark for a 
particular license area, its authorization for each license area in 
which it fails to meet the Second Performance Benchmark shall terminate 
automatically without Commission action, and the licensee will be 
ineligible to regain it if the Commission makes the license available at 
a later date.
    (3) Compliance procedures. To demonstrate compliance with the 
performance requirements in paragraph (w)(1) of this section, licensees 
shall use the most recently available decennial U.S. Census Data at the 
time of measurement and shall base their measurements of population or 
geographic area served on areas no larger than the Census Tract level. 
The population or area within a specific Census Tract (or other 
acceptable identifier) will be deemed served by the licensee only if it 
provides reliable signal coverage to and offers service within the 
specific Census Tract (or other acceptable identifier). To the extent 
the Census Tract (or other acceptable identifier) extends beyond the 
boundaries of a license area, a licensee with authorizations for such 
areas may include only the population or geographic area within the 
Census Tract (or other acceptable identifier) towards meeting the 
performance requirement of a single, individual license. If a licensee 
does not provide reliable signal coverage to an entire license area, the 
license must provide a map that accurately depicts the boundaries of the 
area or areas within each license area not being served. Each licensee 
also must file supporting documentation certifying the type of service 
it is providing for each licensed area within its service territory and 
the type of technology used to provide such service. Supporting 
documentation must include the assumptions used to create the coverage 
maps, including the propagation model and the signal strength necessary 
to provide reliable service with the licensee's technology.

Sec.  27.15  Geographic partitioning and spectrum disaggregation.

    (a) Eligibility. (1) Parties seeking approval for partitioning and 
disaggregation shall request from the Commission an authorization for 
partial assignment of a license pursuant to Sec.  1.948.
    (2) AWS and WCS licensees may apply to partition their licensed 
geographic service area or disaggregate their licensed spectrum at any 
time following the grant of their licenses.
    (b) Technical Standards--(1) Partitioning. In the case of 
partitioning, applicants and licensees must file FCC Form 603 pursuant 
to section 1.948 and list the partitioned service area on a schedule to 
the application. The geographic coordinates must be specified in 
degrees, minutes, and seconds to the nearest second of latitude and 
longitude and must be based upon the 1983 North American Datum (NAD83).
    (2) Disaggregation. Spectrum may be disaggregated in any amount.
    (3) Combined partitioning and disaggregation. The Commission will 
consider requests for partial assignment of licenses that propose 
combinations of partitioning and disaggregation.
    (4) Signal levels. For purposes of partitioning and disaggregation, 
part 27 systems must be designed so as not to exceed the signal level 
specified for the particular spectrum block in Sec.  27.55 at the 
licensee's service area boundary, unless the affected adjacent service 
area licensees have agreed to a different signal level.
    (c) License term. The license term for a partitioned license area

Sec.  27.16  Network access requirements for Block C in the 746-757
and 776-787 MHz bands.

    (a) Applicability. This section shall apply only to the 
authorizations for Block C in the 746-757 and 776-787 MHz bands assigned 
and only if the results of the first auction in which licenses for such 
authorizations are offered satisfied the applicable reserve price.
    (b) Use of devices and applications. Licensees offering service on 
spectrum subject to this section shall not deny, limit, or restrict the 
ability of their customers to use the devices and applications of their 
choice on the licensee's C Block network, except:
    (1) Insofar as such use would not be compliant with published 
technical standards reasonably necessary for the management or 
protection of the licensee's network, or
    (2) As required to comply with statute or applicable government 
regulation.
    (c) Technical standards. For purposes of paragraph (b)(1) of this 
section:
    (1) Standards shall include technical requirements reasonably 
necessary for third parties to access a licensee's network via devices 
or applications without causing objectionable interference to other 
spectrum users or jeopardizing network security. The potential for 
excessive bandwidth demand alone shall not constitute grounds for 
denying, limiting or restricting access to the network.
    (2) To the extent a licensee relies on standards established by an 
independent standards-setting body which is open to participation by 
representatives of service providers, equipment manufacturers, 
application developers, consumer organizations, and other interested 
parties, the standards will carry a presumption of reasonableness.
    (3) A licensee shall publish its technical standards, which shall be 
non-proprietary, no later than the time at which it makes such standards 
available to any preferred vendors, so that the standards are readily 
available to customers, equipment manufacturers, application developers, 
and other parties interested in using or developing products for use on 
a licensee's networks.

[[Page 340]]

    (d) Access requests. (1) Licensees shall establish and publish clear 
and reasonable procedures for parties to seek approval to use devices or 
applications on the licensees' networks. A licensee must also provide to 
potential customers notice of the customers' rights to request the 
attachment of a device or application to the licensee's network, and 
notice of the licensee's process for customers to make such requests, 
including the relevant network criteria.
    (2) If a licensee determines that a request for access would violate 
its technical standards or regulatory requirements, the licensee shall 
expeditiously provide a written response to the requester specifying the 
basis for denying access and providing an opportunity for the requester 
to modify its request to satisfy the licensee's concerns.
    (e) Handset locking prohibited. No licensee may disable features on 
handsets it provides to customers, to the extent such features are 
compliant with the licensee's standards pursuant to paragraph (b)of this 
section, nor configure handsets it provides to prohibit use of such 
handsets on other providers' networks.
    (f) Burden of proof. Once a complainant sets forth a prima facie 
case that the C Block licensee has refused to attach a device or 
application in violation of the requirements adopted in this section, 
the licensee shall have the burden of proof to demonstrate that it has 
adopted reasonable network standards and reasonably applied those 
standards in the complainant's case. Where the licensee bases its 
network restrictions on industry-wide consensus standards, such 
restrictions would be presumed reasonable.

bandwidth.
    (B) The peak-to-average power ratio (PAPR) of the transmitter output 
power must not exceed 13 dB. The PAPR measurements should be made using 
either an instrument with complementary cumulative distribution function 
(CCDF) capabilities to determine that PAPR will not exceed 13 dB for 
more than 0.1 percent of the time or other Commission approved 
procedure. The measurement must be performed using a signal 
corresponding to the highest PAPR expected during periods of continuous 
transmission.
    (ii) For base and fixed stations transmitting in the 2315-2320 MHz 
band or the 2345-2350 MHz band, the peak EIRP must not exceed 2,000 
watts.
    (2) Fixed customer premises equipment stations. For fixed customer 
premises equipment (CPE) stations transmitting in the 2305-2320 MHz band 
or in the 2345-2360 MHz band, the peak EIRP must not exceed 20 watts 
within any 5 megahertz of authorized bandwidth. Fixed CPE stations 
transmitting in the 2305-2320 MHz band or in the 2345-2360 MHz band must 
employ automatic transmit power control when operating so the stations 
operate with the minimum power necessary for successful communications. 
The use of outdoor antennas for CPE stations or outdoor CPE station 
installations operating with 2 watts per 5 megahertz or less average 
EIRP using the stepped emissions mask prescribed in Sec.  27.53(a)(3) is 
prohibited except if professionally installed in locations removed by 20 
meters from roadways or in locations where it can be shown that the 
ground power level of -44 dBm in the A or B blocks or -55 dBm in the C 
or D blocks will not be exceeded at the nearest road location. The use 
of outdoor antennas for fixed CPE stations operating with 2 watts per 5 
megahertz or less average EIRP and the emissions mask prescribed in 
Sec.  27.53(a)(1)(i) through (iii) is permitted in all locations. For 
fixed WCS CPE using TDD technology, the duty cycle must not exceed 38 
percent;

[[Page 341]]

    (3) Mobile and portable stations. (i) For mobile and portable 
stations transmitting in the 2305-2315 MHz band or the 2350-2360 MHz 
band, the average EIRP must not exceed 50 milliwatts within any 1 
megahertz of authorized bandwidth, except that for mobile and portable 
stations compliant with 3GPP LTE standards or another advanced mobile 
broadband protocol that avoids concentrating energy at the edge of the 
operating band the average EIRP must not exceed 250 milliwatts within 
any 5 megahertz of authorized bandwidth but may exceed 50 milliwatts 
within any 1 megahertz of authorized bandwidth. For mobile and portable 
stations using time division duplexing (TDD) technology, the duty cycle 
must not exceed 38 percent in the 2305-2315 MHz and 2350-2360 MHz bands. 
Mobile and portable stations using FDD technology are restricted to 
transmitting in the 2305-2315 MHz band. Power averaging shall not 
include intervals in which the transmitter is off.
    (ii) Mobile and portable stations are not permitted to transmit in 
the 2315-2320 MHz and 2345-2350 MHz bands.
    (iii) Automatic transmit power control. Mobile and portable stations 
transmitting in the 2305-2315 MHz band or in the 2350-2360 MHz band must 
employ automatic transmit power control when operating so the stations 
operate with the minimum power necessary for successful communications.
    (iv) Prohibition on external vehicle-mounted antennas. The use of 
external vehicle-mounted antennas for mobile and portable stations 
transmitting in the 2305-2315 MHz band or the 2350-2360 MHz band is 
prohibited.

deploys a network after the 716-722 or 722-728 MHz bands licensee 
deploys a network on its 716-722 or 722-728 MHz spectrum in the same 
geographic market, the 716-722 or 722-728 MHz bands licensee will work 
with the licensee with uplink operations in the 698-716 MHz band to 
identify sites that will require additional filtering, and will help the 
licensee operating in the 698-716 and 728-746 MHz bands to identify 
proper filters;
    (ii) The 716-722 or 722-728 MHz bands licensee must permit licensees

before a licensee in the 716-722 or 722-728 MHz bands deploys a network 
in the same geographic market, the 716-722 or 722-728 MHz bands licensee 
will work with licensees in the 698-716 and 728-746 MHz bands to 
identify sites that will need additional filtering and will purchase and 
pay for installation of required filters on such sites.

of the transmission may not exceed 13 dB.
    (6) Peak transmit power must be measured over any interval of 
continuous transmission using instrumentation calibrated in terms of an

adjusted for any instrument limitations, such as detector response 
times, limited resolution bandwidth capability when compared to the 
emission bandwidth, sensitivity, etc., so as to obtain a true peak 
measurement for the emission in question over the full bandwidth of the 
channel.

    (e) The following power limits apply to the paired 1392-1395 MHz and 
1432-1435 MHz bands as well as the unpaired 1390-1392 MHz band (1.4 GHz 
band):
    (1) Fixed stations transmitting in the 1390-1392 MHz and 1432-1435 
MHz bands are limited to 2000 watts EIRP peak power. Fixed stations 
transmitting in the 1392-1395 MHz band are limited to 100 watts EIRP 
peak power.

power.
    (2) Mobile stations are limited to 4 watts EIRP peak power.
    (g) [Reserved]
    (h) The following power limits shall apply in the BRS and EBS:
    (1) Main, booster and base stations. (i) The maximum EIRP of a main, 
booster or base station shall not exceed 33 dBW + 10log(X/Y) dBW, where 
X is the actual channel width in MHz and Y is either 6 MHz if prior to 
transition or the station is in the MBS following transition or 5.5 MHz 
if the station is in the LBS and UBS following transition, except as 
provided in paragraph (h)(1)(ii) of this section.
    (ii) If a main or booster station sectorizes or otherwise uses one 
or more transmitting antennas with a non-omnidirectional horizontal 
plane radiation pattern, the maximum EIRP in dBW in a given direction 
shall be determined by the following formula: EIRP = 33 dBW + 10 log(X/
Y) dBW + 10

[[Page 346]]

log(360/beamwidth) dBW, where X is the actual channel width in MHz, Y is 
either (i) 6 MHz if prior to transition or the station is in the MBS 
following transition or (ii) 5.5 MHz if the station is in the LBS and 
UBS following transition, and beamwidth is the total horizontal plane 
beamwidth of the individual transmitting antenna for the station or any 
sector measured at the half-power points.
    (2) Mobile and other user stations. Mobile stations are limited to 
2.0 watts EIRP. All user stations are limited to 2.0 watts transmitter 
output power.
    (3) For television transmission, the peak power of the accompanying 
aural signal must not exceed 10 percent of the peak visual power of the 
transmitter. The Commission may order a reduction in aural signal power 
to diminish the potential for harmful interference.
    (4) For main, booster and response stations utilizing digital 
emissions with non-uniform power spectral density (e.g. unfiltered 
QPSK), the power measured within any 100 kHz resolution bandwidth within 
the 6 MHz channel occupied by the non-uniform emission cannot exceed the 
power permitted within any 100 kHz resolution bandwidth within the 6 MHz 
channel if it were occupied by an emission with uniform power spectral 
density, i.e., if the maximum permissible power of a station utilizing a 
perfectly uniform power spectral density across a 6 MHz channel were 
2000 watts EIRP, this would result in a maximum permissible power flux 
density for the station of 2000/60 = 33.3 watts EIRP per 100 kHz 
bandwidth. If a non-uniform emission were substituted at the station, 
station power would still be limited to a maximum of 33.3 watts EIRP 
within any 100 kHz segment of the 6 MHz channel, irrespective of the 
fact that this would result in a total 6 MHz channel power of less than 
2000 watts EIRP.
    (i) Peak transmit power shall be measured over any interval of 
continuous transmission using instrumentation calibrated in terms of 
rms-equivalent voltage. The measurement results shall be properly 
adjusted for any instrument limitations, such as detector response 
times, limited resolution bandwidth capability when compared to the 
emission bandwidth, etc., so as to obtain a true peak measurement for 
the emission in question over the full bandwidth of the channel.

continuous transmission using instrumentation calibrated in terms of an 
rms-equivalent voltage. The measurement results shall be properly 
adjusted for

[[Page 347]]

resolution bandwidth capability when compared to the emission bandwidth, 
sensitivity, and any other relevant factors, so as to obtain a true peak 
measurement for the emission in question over the full bandwidth of the 
channel.

in the 3450-3550 MHz band:
    (1) The power of each fixed or base station transmitting in the

100 or fewer persons per square mile, based upon the most recently 
available population statistics from the Bureau of the Census, is

Watts/MHz. This limit applies to the aggregate power of all antenna 
elements in any given sector of a base station.
    (2) The power of each fixed or base station transmitting in the 
3450-3550 MHz band and situated in any geographic location other than

antenna elements in any given sector of a base station.
    (3) Mobile devices are limited to 1Watt (30 dBm) EIRP. Mobile 
devices operating in these bands must employ a means for limiting power 
to the minimum necessary for successful communications.
    (4) Equipment employed must be authorized in accordance with the

    (5) Measurement procedure. Compliance with these rules is based on 
the use of measurement instrumentation employing a resolution bandwidth 
of 1 MHz or greater. However, in the 1 MHz bands immediately outside and 
adjacent to the channel blocks at 2305, 2310, 2315, 2320, 2345, 2350, 
2355, and 2360 MHz, a resolution bandwidth of at least 1 percent of the 
emission bandwidth of the fundamental emission of the transmitter may be 
employed. A narrower resolution bandwidth is permitted in all cases to 
improve measurement accuracy provided the measured power is integrated 
over the full required measurement bandwidth (i.e., 1 MHz). The emission 
bandwidth is defined as the width of the signal between two points, one 
below the carrier center frequency and one above the carrier center 
frequency, outside of which all emissions are attenuated at least 26 dB 
below the transmitter power.
    (6) [Reserved]
    (7) The measurements of emission power can be expressed in peak or 
average values, provided they are expressed in the same parameters as 
the transmitter power;
    (8) Waiver requests of any of the out-of-band emission limits in 
paragraphs (a)(1) through (a)(7) of this section shall be entertained 
only if interference protection equivalent to that afforded by the 
limits is shown;
    (9) [Reserved]
    (10) The out-of-band emissions limits in paragraphs (a)(1) through 
(a)(3) of this section may be modified by the private contractual 
agreement of all affected licensees, who must maintain a copy of the 
agreement in their station files and disclose it to prospective 
assignees, transferees, or spectrum lessees and, upon request, to the 
Commission.
    (b) For WCS Satellite DARS operations: The limits set forth in Sec.  
25.202(f) of this chapter shall apply, except that Satellite DARS 
operations shall be limited to a maximum power flux density of -197 dBW/
m\2\/4 kHz in the 2370-2390 MHz band at Arecibo, Puerto Rico.
    (c) For operations in the 746-758 MHz band and the 776-788 MHz band, 
the power of any emission outside the licensee's frequency band(s) of 
operation shall be attenuated below the transmitter power (P) within the 
licensed band(s) of operation, measured in watts, in accordance with the 
following:
    (1) On any frequency outside the 746-758 MHz band, the power of any 
emission shall be attenuated outside the band below the transmitter 
power (P) by at least 43 + 10 log (P) dB;
    (2) On any frequency outside the 776-788 MHz band, the power of any 
emission shall be attenuated outside the band below the transmitter 
power (P) by at least 43 + 10 log (P) dB;
    (3) On all frequencies between 763-775 MHz and 793-805 MHz, by a 
factor not less than 76 + 10 log (P) dB in a 6.25 kHz band segment, for 
base and fixed stations;
    (4) On all frequencies between 763-775 MHz and 793-805 MHz, by a 
factor not less than 65 + 10 log (P) dB in a 6.25 kHz band segment, for 
mobile and portable stations;

[[Page 351]]

    (5) Compliance with the provisions of paragraphs (c)(1) and (c)(2) 
of this section is based on the use of measurement instrumentation 
employing a resolution bandwidth of 100 kHz or greater. However, in the 
100 kHz bands immediately outside and adjacent to the frequency block, a 
resolution bandwidth of at least 30 kHz may be employed;
    (6) Compliance with the provisions of paragraphs (c)(3) and (c)(4) 
of this section is based on the use of measurement instrumentation such 
that the reading taken with any resolution bandwidth setting should be 
adjusted to indicate spectral energy in a 6.25 kHz segment.
    (d) [Reserved]
    (e) For operations in the 775-776 MHz and 805-806 MHz bands, 
transmitters must comply with either paragraphs (d)(1) through (5) of 
this section or the ACP emission limitations set forth in paragraphs 
(d)(6) to (d)(9) of this section.
    (1) On all frequencies between 758-775 MHz and 788-805 MHz, the 
power of any emission outside the licensee's frequency bands of 
operation shall be attenuated below the transmitter power (P) within the 
licensed band(s) of operation, measured in watts, by a factor not less 
than 76 + 10 log (P) dB in a 6.25 kHz band segment, for base and fixed 
stations;
    (2) On all frequencies between 758-775 MHz and 788-805 MHz, the 
power of any emission outside the licensee's frequency bands of 
operation shall be attenuated below the transmitter power (P) within the 
licensed band(s) of operation, measured in watts, by a factor not less 
than 65 + 10 log (P) dB in a 6.25 kHz band segment, for mobile and 
portable stations;
    (3) On any frequency outside the 775-776 MHz and 805-806 MHz bands, 
the power of any emission shall be attenuated outside the band below the 
transmitter power (P) within the licensed band(s) of operation, measured 
in watts, by at least 43 + 10 log (P) dB;
    (4) Compliance with the provisions of paragraphs (e)(1) and (e)(2) 
of this section is based on the use of measurement instrumentation such 
that the reading taken with any resolution bandwidth setting should be 
adjusted to indicate spectral energy in a 6.25 kHz segment;
    (5) Compliance with the provisions of paragraph (e)(3) of this 
section is based on the use of measurement instrumentation employing a 
resolution bandwidth of 100 kHz or greater. However, in the 100 kHz 
bands immediately outside and adjacent to the frequency block, a 
resolution bandwidth of at least 30 kHz may be employed.
    (6) The adjacent channel power (ACP) requirements for transmitters 
designed for various channel sizes are shown in the following tables. 
Mobile station requirements apply to handheld, car mounted and control 
station units. The tables specify a value for the ACP as a function of 
the displacement from the channel center frequency and measurement 
bandwidth. In the following tables, ``(s)'' indicates a swept 
measurement may be used.

    (7) ACP measurement procedure. The following procedures are to be 
followed for making ACP transmitter measurements. For time division 
multiple access (TDMA) systems, the measurements are to be made under 
TDMA operation only during time slots when the transmitter is on. All 
measurements must be made at the input to the transmitter's antenna. 
Measurement bandwidth used below implies an instrument that measures the 
power in many narrow bandwidths (e.g., 300 Hz) and integrates these 
powers across a larger band to determine power in the measurement 
bandwidth.
    (i) Setting reference level. Using a spectrum analyzer capable of 
ACP measurements, set the measurement bandwidth to the channel size. For 
example, for a 6.25 kHz transmitter, set the measurement bandwidth to 
6.25 kHz; for a 150 kHz transmitter, set the measurement bandwidth to 
150 kHz. Set the frequency offset of the measurement bandwidth to zero 
and adjust the center frequency of the spectrum analyzer to give the 
power level in the measurement bandwidth. Record this power level in dBm 
as the ``reference power level''.
    (ii) Non-swept power measurement. Using a spectrum analyzer capable 
of ACP measurements, set the measurement bandwidth as shown in the 
tables above. Measure the ACP in dBm. These measurements should be made 
at maximum power. Calculate the coupled power by subtracting the 
measurements made in this step from the reference power measured in the 
previous step. The absolute ACP values must be less than the values 
given in the table for each condition above.
    (iii) Swept power measurement. Set a spectrum analyzer to 30 kHz 
resolution bandwidth, 1 MHz video bandwidth and sample mode detection. 
Sweep MHz from the carrier frequency. Set the 
reference level to the RMS value of the transmitter power and note the 
absolute power. The response at frequencies greater than 600 kHz must be 
less than the values in the tables above.
    (8) Out-of-band emission limit. On any frequency outside of the 
frequency ranges covered by the ACP tables in this section, the power of 
any emission must be reduced below the unmodulated carrier power (P) by 
at least 43 + 10 log (P) dB.
    (9) Authorized bandwidth. Provided that the ACP requirements of this 
section are met, applicants may request any authorized bandwidth that 
does not exceed the channel size.
    (f) For operations in the 746-758 MHz, 775-788 MHz, and 805-806 MHz 
bands, emissions in the band 1559-1610 MHz shall be limited to -70 dBW/
MHz equivalent isotropically radiated power (EIRP) for wideband signals, 
and -80 dBW EIRP for discrete emissions of less than 700 Hz bandwidth. 
For the purpose of equipment authorization, a transmitter shall be 
tested with an antenna that is representative of the type that will be 
used with the equipment in normal operation.
    (g) For operations in the 600 MHz band and the 698-746 MHz band, the 
power of any emission outside a licensee's frequency band(s) of 
operation shall be attenuated below the transmitter power (P) within the 
licensed band(s) of operation, measured in watts, by at least 43 + 10 
log (P) dB. Compliance with this provision is based on the use of 
measurement instrumentation employing a resolution bandwidth of 100 
kilohertz or greater. However, in the 100 kilohertz bands immediately 
outside and adjacent to a licensee's frequency block, a resolution 
bandwidth of at least 30 kHz may be employed.
    (h) AWS emission limits--(1) General protection levels. Except as 
otherwise specified below, for operations in the 1695-1710 MHz, 1710-
1755 MHz, 1755-1780 MHz, 1915-1920 MHz, 1995-2000 MHz, 2000-2020 MHz, 
2110-2155 MHz, 2155-2180 MHz, and 2180-2200 bands, the power of any 
emission outside a licensee's frequency block shall be attenuated below 
the transmitter power (P) in watts by at least 43 + 10 log10 
(P) dB.
    (2) Additional protection levels. Notwithstanding the foregoing 
paragraph (h)(1) of this section:
    (i) Operations in the 2180-2200 MHz band are subject to the out-of-
band emission requirements set forth in Sec.  27.1134 for the protection 
of federal government operations operating in the 2200-2290 MHz band.
    (ii) For operations in the 2000-2020 MHz band, the power of any 
emissions

[[Page 354]]

below 2000 MHz shall be attenuated below the transmitter power (P) in 
watts by at least 70 + 10 log10(P) dB.
    (iii) For operations in the 1915-1920 MHz band, the power of any 
emission between 1930-1995 MHz shall be attenuated below the transmitter 
power (P) in watts by at least 70 + 10 log10(P) dB.
    (iv) For operations in the 1995-2000 MHz band, the power of any 
emission between 2005-2020 MHz shall be attenuated below the transmitter 
power (P) in watts by at least 70 + 10 log10(P) dB.
    (3) Measurement procedure. (i) Compliance with this provision is 
based on the use of measurement instrumentation employing a resolution 
bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands 
immediately outside and adjacent to the licensee's frequency block, a 
resolution bandwidth of at least one percent of the emission bandwidth 
of the fundamental emission of the transmitter may be employed. The 
emission bandwidth is defined as the width of the signal between two 
points, one below the carrier center frequency and one above the carrier 
center frequency, outside of which all emissions are attenuated at least 
26 dB below the transmitter power.
    (ii) When measuring the emission limits, the nominal carrier 
frequency shall be adjusted as close to the licensee's frequency block 
edges, both upper and lower, as the design permits.
    (iii) The measurements of emission power can be expressed in peak or 
average values, provided they are expressed in the same parameters as 
the transmitter power.
    (4) Private agreements. (i) For AWS operations in the 2000-2020 MHz 
and 2180-2200 MHz bands, to the extent a licensee establishes unified 
operations across the AWS blocks, that licensee may choose not to 
observe the emission limit specified in paragraph (h)(1), above, 
strictly between its adjacent block licenses in a geographic area, so 
long as it complies with other Commission rules and is not adversely 
affecting the operations of other parties by virtue of exceeding the 
emission limit.
    (ii) For AWS operations in the 2000-2020 MHz band, a licensee may 
enter into private agreements with all licensees operating between 1995 
and 2000 MHz to allow the 70 + 10 log10(P) dB limit to be 
exceeded within the 1995-2000 MHz band.
    (iii) An AWS licensee who is a party to a private agreement 
described in this section (4) must maintain a copy of the agreement in 
its station files and disclose it, upon request, to prospective AWS 
assignees, transferees, or spectrum lessees and to the Commission.
    (i) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.
    (j)(1) For operations in the unpaired 1390-1392 MHz band and the 
paired 1392-1395 MHz and 1432-1435 MHz bands, the power of any emission 
outside the licensee's frequency band(s) of operation shall be 
attenuated below the transmitter power (P) by at least 43 + 10 log (P) 
dB. Compliance with these provisions is based on the procedures 
described in paragraph (a)(5) of this section.
    (2) In the 1390-1395 MHz and 1432-1435 MHz bands, licensees are 
encouraged to take all reasonable steps to ensure that unwanted emission 
power does not exceed the following levels in the band 1400-1427 MHz:
    (i) For stations of point-to-point systems in the fixed service: -45 
dBW/27 MHz.
    (ii) For stations in the mobile service: -60 dBW/27 MHz.
    (k) For operations in the 1670-1675 MHz, the power of any emission 
outside the licensee's frequency band(s) of operation shall be 
attenuated below the transmitter power (P) by at least 43 + 10 log (P) 
dB. Compliance with these provisions is based on the procedures 
described in paragraph (a)(5) of this section.
    (l) 3.7 GHz Service. The following emission limits apply to stations 
transmitting in the 3700-3980 MHz band:
    (1) For base station operations in the 3700-3980 MHz band, the 
conducted power of any emission outside the licensee's authorized 
bandwidth shall not exceed -13 dBm/MHz. Compliance with this paragraph 
(l)(1) is based on the use of measurement instrumentation employing a 
resolution bandwidth of 1 megahertz or greater. However, in the 1 
megahertz bands immediately

[[Page 355]]

outside and adjacent to the licensee's frequency block, a resolution 
bandwidth of at least one percent of the emission bandwidth of the 
fundamental emission of the transmitter may be employed. The emission 
bandwidth is defined as the width of the signal between two points, one 
below the carrier center frequency and one above the carrier center 
frequency, outside of which all emissions are attenuated at least 26 dB 
below the transmitter power.
    (2) For mobile operations in the 3700-3980 MHz band, the conducted 
power of any emission outside the licensee's authorized bandwidth shall 
not exceed -13 dBm/MHz. Compliance with this paragraph (l)(2) is based 
on the use of measurement instrumentation employing a resolution 
bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands 
immediately outside and adjacent to the licensee's frequency block, the 
minimum resolution bandwidth for the measurement shall be either one 
percent of the emission bandwidth of the fundamental emission of the 
transmitter or 350 kHz. In the bands between 1 and 5 MHz removed from 
the licensee's frequency block, the minimum resolution bandwidth for the 
measurement shall be 500 kHz. The emission bandwidth is defined as the 
width of the signal between two points, one below the carrier center 
frequency and one above the carrier center frequency, outside of which 
all emissions are attenuated at least 26 dB below the transmitter power.
    (m) For BRS and EBS stations, the power of any emissions outside the 
licensee's frequency bands of operation shall be attenuated below the 
transmitter power (P) measured in watts in accordance with the standards 
below. If a licensee has multiple contiguous channels, out-of-band 
emissions shall be measured from the upper and lower edges of the 
contiguous channels.
    (1) Prior to the transition, and thereafter, solely within the MBS, 
for analog operations with an EIRP in excess of -9 dBW, the signal shall 
be attenuated at the channel edges by at least 38 dB relative to the 
peak visual carrier, then linearly sloping from that level to at least 
60 dB of attenuation at 1 MHz below the lower band edge and 0.5 MHz 
above the upper band edge, and attenuated at least 60 dB at all other 
frequencies.
    (2) For digital base stations, the attenuation shall be not less 
than 43 + 10 log (P) dB, unless a documented interference complaint is 
received from an adjacent channel licensee with an overlapping 
Geographic Service Area. Mobile Satellite Service licensees operating on 
frequencies below 2495 MHz may also submit a documented interference 
complaint against BRS licensees operating on channel BRS No. 1 on the 
same terms and conditions as adjacent channel BRS or EBS licensees. 
Provided that a documented interference complaint cannot be mutually 
resolved between the parties prior to the applicable deadline, then the 
following additional attenuation requirements shall apply:
    (i) If a pre-existing base station suffers harmful interference from 
emissions caused by a new or modified base station located 1.5 km or 
more away, within 24 hours of the receipt of a documented interference 
complaint the licensee of the new or modified base station must 
attenuate its emissions by at least 67 + 10 log (P) dB measured at 3 
megahertz, above or below, from the channel edge of its frequency block 
and shall immediately notify the complaining licensee upon 
implementation of the additional attenuation. No later than 60 days 
after the implementation of such additional attenuation, the licensee of 
the complaining base station must attenuate its base station emissions 
by at least 67 + 10 log (P) dB measured at 3 megahertz, above or below, 
from the channel edge of its frequency block of the new or modified base 
station.
    (ii) If a pre-existing base station suffers harmful interference 
from emissions caused by a new or modified base station located less 
than 1.5 km away, within 24 hours of receipt of a documented 
interference complaint the licensee of the new or modified base station 
must attenuate its emissions by at least 67 + 10 log (P)-20 log (Dkm/
1.5) dB measured at 3 megahertz, above or below, from the channel edge 
of its frequency block of the complaining licensee, or if both base 
stations are co-located, limit its undesired signal level

[[Page 356]]

at the pre-existing base station receiver(s) to no more than -107 dBm 
measured in a 5.5 megahertz bandwidth and shall immediately notify the 
complaining licensee upon such reduction in the undesired signal level. 
No later than 60 days after such reduction in the undesired signal 
level, the complaining licensee must attenuate its base station 
emissions by at least 67 + 10 log (P) dB measured at 3 megahertz, above 
or below, from the channel edge of its frequency block of the new or 
modified base station.
    (iii) If a new or modified base station suffers harmful interference 
from emissions caused by a pre-existing base station located 1.5 km or 
more away, within 60 days of receipt of a documented interference 
complaint the licensee of each base station must attenuate its base 
station emissions by at least 67 + 10 log (P) dB measured at 3 
megahertz, above or below, from the channel edge of its frequency block 
of the other licensee.
    (iv) If a new or modified base station suffers harmful interference 
from emissions caused by a pre-existing base station located less than 
1.5 km away, within 60 days of receipt of a documented interference 
complaint: (a) The licensee of the new or modified base station must 
attenuate its OOBE by at least 67 + 10 log (P)-20 log (Dkm/1.5) measured 
3 megahertz above or below, from the channel edge of its frequency block 
of the other licensee, or if the base stations are co-located, limit its 
undesired signal level at the other base station receiver(s) to no more 
than -107 dBm measured in a 5.5-megahertz bandwidth; and (b) the 
licensee causing the interference must attenuate its emissions by at 
least 67 + 10 log (P) dB measured at 3 megahertz, above or below, from 
the channel edge of its frequency block of the new or modified base 
station.
    (v) For all fixed digital user stations, the attenuation factor 
shall be not less than 43 + 10 log (P) dB at the channel edge.
    (3) Prior to transition and thereafter solely within the MBS, and 
notwithstanding paragraph (l)(2) of this section, the maximum out-of-
band power of a digital transmitter operating on a single 6 MHz channel 
with an EIRP in excess of -9 dBW employing digital modulation for the 
primary purpose of transmitting video programming shall be attenuated at 
the 6 MHz channel edges at least 25 dB relative to the licensed average 
6 MHz channel power level, then attenuated along a linear slope to at 
least 40 dB at 250 kHz beyond the nearest channel edge, then attenuated 
along a linear slope from that level to at least 60 dB at 3 MHz above 
the upper and below the lower licensed channel edges, and attenuated at 
least 60 dB at all other frequencies.
    (4) For mobile digital stations, the attenuation factor shall be not 
less than 40 + 10 log (P) dB on all frequencies between the channel edge 
and 5 megahertz from the channel edge, 43 + 10 log (P) dB on all 
frequencies between 5 megahertz and X megahertz from the channel edge, 
and 55 + 10 log (P) dB on all frequencies more than X megahertz from the 
channel edge, where X is the greater of 6 megahertz or the actual 
emission bandwidth as defined in paragraph (m)(6) of this section. In 
addition, the attenuation factor shall not be less that 43 + 10 log (P) 
dB on all frequencies between 2490.5 MHz and 2496 MHz and 55 + 10 log 
(P) dB at or below 2490.5 MHz. Mobile Satellite Service licensees 
operating on frequencies below 2495 MHz may also submit a documented 
interference complaint against BRS licensees operating on channel BRS 
Channel 1 on the same terms and conditions as adjacent channel BRS or 
EBS licensees.
    (5) Notwithstanding the provisions of paragraphs (l)(2) and (l)(4) 
of this section, prior to transition, a licensee may continue to operate 
facilities deployed as of January 10, 2005 provided that such facilities 
operate in compliance with the emission mask applicable to those 
services prior to January 10, 2005.
    (6) Measurement procedure. Compliance with these rules is based on 
the use of measurement instrumentation employing a resolution bandwidth 
of 1 megahertz or greater. However, in the 1 MHz bands immediately 
outside and adjacent to the frequency block a resolution bandwidth of at 
least one percent of the emission bandwidth of the fundamental emission 
of the transmitter may be employed; for mobile

[[Page 357]]

digital stations, in the 1 megahertz bands immediately outside and 
adjacent to the frequency block a resolution bandwidth of at least two 
percent may be employed, except when the 1 megahertz band is 2495-2496 
MHz, in which case a resolution bandwidth of at least one percent may be 
employed. A narrower resolution bandwidth is permitted in all cases to 
improve measurement accuracy provided the measured power is integrated 
over the full required measurement bandwidth (i.e. 1 megahertz or 1 
percent of emission bandwidth, as specified; or 1 megahertz or 2 percent 
for mobile digital stations, except in the band 2495-2496 MHz). The 
emission bandwidth is defined as the width of the signal between two 
points, one below the carrier center frequency and one above the carrier 
center frequency, outside of which all emissions are attenuated at least 
26 dB below the transmitter power. With respect to television 
operations, measurements must be made of the separate visual and aural 
operating powers at sufficiently frequent intervals to ensure compliance 
with the rules.
    (7) Alternative out of band emission limit. Licensees in this 
service may establish an alternative out of band emission limit to be 
used at specified band edge(s) in specified geographical areas, in lieu 
of that set forth in this section, pursuant to a private contractual 
arrangement of all affected licensees and applicants. In this event, 
each party to such contract shall maintain a copy of the contract in 
their station files and disclose it to prospective assignees or 
transferees and, upon request, to the FCC.
    (n) 3.45 GHz Service. The following emission limits apply to 
stations transmitting in the 3450-3550 MHz band:
    (1) For base station operations in the 3450-3550 MHz band, the 
conducted power of any emission outside the licensee's authorized 
bandwidth shall not exceed -13 dBm/MHz. Compliance with the provisions 
of this paragraph (n)(1) is based on the use of measurement 
instrumentation employing a resolution bandwidth of 1 megahertz or 
greater. However, in the 1 megahertz bands immediately outside and 
adjacent to the licensee's frequency block, a resolution bandwidth of at 
least one percent of the emission bandwidth of the fundamental emission 
of the transmitter may be employed, but limited to a maximum of 200 kHz. 
The emission bandwidth is defined as the width of the signal between two 
points, one below the carrier center frequency and one above the carrier 
center frequency, outside of which all emissions are attenuated at least 
26 dB below the transmitter power. Notwithstanding the channel edge 
requirement of -13 dBm per megahertz, for base station operations in the 
3450-3550 MHz band, the conducted power of any emission below 3440 MHz 
or above 3560 MHz shall not exceed -25 dBm/MHz, and the conducted power 
of emissions below 3430 MHz or above 3570 MHz shall not exceed -40 dBm/
MHz.
    (2) For mobile operations in the 3450-3550 MHz band, the conducted 
power of any emission outside the licensee's authorized bandwidth shall 
not exceed -13 dBm/MHz. Compliance with this paragraph (n)(2) is based 
on the use of measurement instrumentation employing a resolution 
bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands 
immediately outside and adjacent to the licensee's frequency block, a 
resolution bandwidth of at least one percent of the emission bandwidth 
of the fundamental emission of the transmitter may be employed, but 
limited to a maximum of 200 kHz. In the bands between 1 and 5 MHz 
removed from the licensee's frequency block, the minimum resolution 
bandwidth for the measurement shall be 500 kHz. The emission bandwidth 
is defined as the width of the signal between two points, one below the 
carrier center frequency and one above the carrier center frequency, 
outside of which all emissions are attenuated at least 26 dB below the 
transmitter power.
    (o) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.

Sec.  27.54  Frequency stability.

    The frequency stability shall be sufficient to ensure that the 
fundamental emissions stay within the authorized bands of operation.



Sec.  27.55  Power strength limits.

    (a) Field strength limits. For the following bands, the predicted or 
measured median field strength at any location on the geographical 
border of a licensee's service area shall not exceed the value specified 
unless the adjacent affected service area licensee(s) agree(s) to a 
different field strength. This value applies to both the initially 
offered service areas and to partitioned service areas.
    (1) 1995-2000 MHz, 2110-2155, 2155-2180, 2180-2200, 2305-2320, and 
2345-2360 MHz bands: 47 dB[micro]V/m.
    (2) 600 MHz, 698-758, and 775-787 MHz bands: 40 dB[micro]V/m.
    (3) The paired 1392-1395 MHz and 1432-1435 MHz bands and the 
unpaired 1390-1392 MHz band (1.4 GHz band): 47 dB[micro]V/m.
    (4) BRS and EBS: The predicted or measured median field strength at 
any location on the geographical border of a licensee's service area 
shall not exceed the value specified unless the adjacent affected 
service area licensee(s) agree(s) to a different field strength. This 
value applies to both the initially offered services areas and to 
partitioned services areas. Licensees may exceed this signal level where 
there is no affected licensee that is constructed and providing service. 
Once the affected licensee is providing service, the original licensee 
will be required to take whatever steps necessary to comply with the 
applicable power level at its GSA boundary, absent consent from the 
affected licensee.
    (i) Prior to transition, the signal strength at any point along the 
licensee's GSA boundary does not exceed the greater of that permitted 
under the licensee's Commission authorizations as of January 10, 2005 or 
47 dB[micro]V/m.
    (ii) Following transition, for stations in the LBS and UBS, the 
signal strength at any point along the licensee's GSA boundary must not 
exceed 47 dB[micro]V/m. This field strength is to be measured at 1.5 
meters above the ground over the channel bandwidth (i.e., each 5.5 MHz 
channel for licensees that hold a full channel block, and for the 5.5 
MHz channel for licensees that hold individual channels).
    (iii) Following transition, for stations in the MBS, the signal 
strength at any point along the licensee's GSA boundary must not exceed 
the greater of -73.0 + 10 log(X/6) dBW/m\2\, where X is the bandwidth in 
megahertz of the channel, or for facilities that are substantially 
similar to the licensee's pre-transition facilities (including 
modifications that do not alter the fundamental nature or use of the 
transmissions), the signal strength at such point that resulted from the 
station's operations immediately prior to the transition, provided that 
such operations complied with paragraph (a)(4)(i) of this section.
    (b) Power flux density limit for stations operating in the 698-746 
MHz bands. For base and fixed stations operating in the 698-746 MHz band 
in accordance with the provisions of Sec.  27.50(c)(6), the power flux 
density that would be produced by such stations through a combination of 
antenna height and vertical gain pattern must not exceed 3000 microwatts 
per square meter on the ground over the area extending to 1 km from the 
base of the antenna mounting structure.
    (c) Power flux density limit for stations operating in the 746-757 
MHz and 776-787 MHz bands. For base and fixed stations operating in the 
746-757 MHz and 776-787 MHz bands in accordance with the provisions of 
Sec.  27.50(b)(6), the power flux density that would be produced by such 
stations through a combination of antenna height and vertical gain 
pattern must not exceed 3000 microwatts per square meter on the ground 
over the area extending to 1 km from the base of the antenna mounting 
structure.
    (d) Power flux density for stations operating in the 3700-3980 MHz 
band. For base and fixed stations operation in the 3700-3980 MHz band in 
accordance with the provisions of Sec.  27.50(j), the power flux density 
(PFD) at any location on the geographical border of a licensee's service 
area shall not exceed -76 dBm/m\2\/MHz. This power flux density will be 
measured at 1.5 meters above ground. Licensees in adjacent geographic 
areas may voluntarily agree to operate under

[[Page 359]]

a higher PFD at their common boundary.
    (e) Power flux density for stations operating in the 3450-3550 MHz 
band. For base and fixed stations operation in the 3450-3550 MHz band in 
accordance with the provisions of Sec.  27.50(k), the power flux density 
(PFD) at any location on the geographical border of a licensee's service 
area shall not exceed -76 dBm/m\2\/MHz. This power flux density will be 
measured at 1.5 meters above ground. Licensees in adjacent geographic 
areas may voluntarily agree to operate under a higher PFD at their 
common boundary.

Sec.  27.56  Antenna structures; air navigation safety.

    A licensee that owns its antenna structure(s) must not allow such 
antenna structure(s) to become a hazard to air navigation. In general, 
antenna structure owners are responsible for registering antenna 
structures with the FCC if required by part 17 of this chapter, and for 
installing and maintaining any required marking and lighting. However, 
in the event of default of this responsibility by an antenna structure 
owner, the FCC permittee or licensee authorized to use an affected 
antenna structure will be held responsible by the FCC for ensuring that 
the antenna structure continues to meet the requirements of part 17 of 
this chapter. See Sec.  17.6 of this chapter.
    (a) Marking and lighting. Antenna structures must be marked, lighted 
and maintained in accordance with part 17 of this chapter and all 
applicable rules and requirements of the Federal Aviation 
Administration. For any construction or alteration that would exceed the 
requirements of section 17.7 of this chapter, licensees must notify the 
appropriate Regional Office of the Federal Aviation Administration (FAA 
Form 7460-1) and file a request for antenna height clearance and 
obstruction marking and lighting specifications (FCC Form 854) with the 
FCC, WTB, 1270 Fairfield Road, Gettysburg, PA 17325.
    (b) Maintenance contracts. Antenna structure owners (or licensees 
and permittees, in the event of default by an antenna structure owner) 
may enter into contracts with other entities to monitor and carry out 
necessary maintenance of antenna structures. Antenna structure owners 
(or licensees and permittees, in the event of default by an antenna 
structure owner) that make such contractual arrangements continue to be 
responsible for the maintenance of antenna structures in regard to air 
navigation safety.



Sec.  27.57  International coordination.

    (a) WCS operations in the border areas shall be subject to 
coordination with those countries and provide protection to non-U.S. 
operations in the 2305-2320 and 2345-2360 MHz bands as appropriate. In 
addition, satellite DARS operations in WCS spectrum shall be subject to 
international satellite coordination procedures.
    (b) Wireless operations in the 512-608 MHz, 614-763 MHz, 775-793 
MHz, and 805-806 MHz bands are subject to current and future 
international agreements between the United States and Canada and the 
United States and Mexico. Unless otherwise modified by international 
treaty, licenses must not cause interference to, and must accept harmful 
interference from, television broadcast operations in Mexico and Canada, 
where these services are co-primary in the band.
    (c) Operation in the 1695-1710 MHz, 1710-1755 MHz, 1755-1780 MHz, 
1915-1920 MHz, 1995-2000 MHz, 2000-2020 MHz, 2110-2155 MHz, 2155-2180 
MHz, 2180-2200 MHz, 3450-3550 MHz, and 3700-3980 MHz bands is subject to 
international agreements with Mexico and Canada.

Sec.  27.58  Interference to BRS/EBS receivers.

    (a) WCS licensees shall bear full financial obligation to remedy 
interference to BRS/EBS block

[[Page 360]]

downconverters if all of the following conditions are met:
    (1) The complaint is received by the WCS licensee prior to February 
20, 2002;
    (2) The BRS/EBS downconverter was installed prior to August 20, 
1998;
    (3) The WCS fixed or land station transmits at 50 or more watts peak 
EIRP;
    (4) The BRS/EBS downconverter is located within a WCS transmitter's 
free space power flux density contour of -34 dBW/m\2\; and
    (5) The BRS/EBS customer or licensee has informed the WCS licensee 
of the interference within one year from the initial operation of the 
WCS transmitter or within one year from any subsequent power increases 
at the WCS station.
    (b) Resolution of the complaint shall be at no cost to the 
complainant.
    (c) Two or more WCS licensees collocating their antennas on the same 
tower shall assume shared responsibility for remedying interference 
complaints within the area determined by paragraph (a)(4) of this 
section unless an offending station can be readily determined and then 
that station shall assume full financial responsibility.
    (d) If the WCS licensee cannot otherwise eliminate interference 
caused to BRS/EBS reception, then that licensee must cease operations 
from the offending WCS facility.
    (e) At least 30 days prior to commencing operations from any new WCS 
transmission site or with increased power from any existing WCS 
transmission site, a WCS licensee shall notify all BRS/EBS licensees in 
or through whose licensed service areas they intend to operate of the 
technical parameters of the WCS transmission facility. WCS and BRS/EBS 
licensees are expected to coordinate voluntarily and in good faith to 
avoid interference problems and to allow the greatest operational 
flexibility in each other's operations.

Sec.  27.59  [Reserved]



Sec.  27.60  TV/DTV interference protection criteria.

    Base, fixed, control, and mobile transmitters in the 698-758 MHz, 
775-788 MHz, and 805-806 MHz frequency bands must be operated only in 
accordance with the rules in this section to reduce the potential for 
interference to public reception of the signals of existing TV and DTV 
broadcast stations transmitting on TV Channels 51 through 68.
    (a) D/U ratios. Licensees must choose site locations that are a 
sufficient distance from co-channel and adjacent channel TV and DTV 
stations, and/or must use reduced transmitting power or transmitting 
antenna height such that the following minimum desired signal-to-
undesired signal ratios (D/U ratios) are met.
    (1) The minimum D/U ratio for co-channel stations is:
    (i) 40 dB at the hypothetical Grade B contour (64 dB[micro]V/m) 
(88.5 kilometers (55 miles)) of the TV station;
    (ii) For transmitters operating in the 698-746 MHz frequency band, 
23 dB at the equivalent Grade B contour (41 dB[micro]V/m) (88.5 
kilometers (55 miles)) of the DTV station; or
    (iii) For transmitters operating in the 746-758 MHz, 775-788 MHz, 
and 805-806 MHz frequency bands, 17 dB at the equivalent Grade B contour 
(41 dB[micro]V/m) (88.5 kilometers (55 miles)) of the DTV station.
    (2) The minimum D/U ratio for adjacent channel stations is 0 dB at 
the hypothetical Grade B contour (64 dB[micro]V/m) (88.5 kilometers (55 
miles)) of the TV station or -23 dB at the equivalent Grade B contour 
(41 dB[micro]V/m) (88.5 kilometers (55 miles)) of the DTV station.
    (b) TV stations and calculation of contours. The methods used to 
calculate TV contours and antenna heights above average terrain are 
given in Sec. Sec.  73.683 and 73.684 of this chapter. Tables to 
determine the necessary minimum distance from the 698-758 MHz, 775-788 
MHz, and 805-806 MHz station to the TV/DTV station, assuming that the 
TV/DTV station has a hypothetical or equivalent Grade B contour of 88.5 
kilometers (55 miles), are located in Sec.  90.309 of this chapter and 
labeled as Tables B, D, and E. The locations of existing and

[[Page 361]]

proposed TV/DTV stations during the period of transition from analog to 
digital TV service are given in part 73 of this chapter and in the final 
proceedings of MM Docket No. 87-268.
    (1) Licensees of stations operating within the ERP and HAAT limits 
of Sec.  27.50 must select one of four methods to meet the TV/DTV 
protection requirements, subject to Commission approval:
    (i) Utilize the geographic separation specified in Tables B, D, and 
E of Sec.  90.309 of this chapter, as appropriate;
    (ii) When station parameters are greater than those indicated in the 
tables, calculate geographic separation in accordance with the required 
D/U ratios, as provided in paragraph (a) of this section;
    (iii) Submit an engineering study justifying the proposed 
separations based on the parameters of the land mobile station and the 
parameters, including authorized and/or applied for facilities, of the 
TV/DTV station(s) it is trying to protect; or,
    (iv) Obtain written concurrence from the applicable TV/DTV 
station(s). If this method is chosen, a copy of the agreement must be 
submitted with the application.
    (2) The following is the method for geographic separations. (i) Base 
and fixed stations that operate in the 746-758 MHz and 775-787 MHz bands 
having an antenna height (HAAT) less than 152 m. (500 ft.) shall afford 
protection to co-channel and adjacent channel TV/DTV stations in 
accordance with the values specified in Table B (co-channel frequencies 
based on 40 dB protection) and Table E (adjacent channel frequencies 
based on 0 dB protection) in Sec.  90.309 of this chapter. Base and 
fixed stations that operate in the 698-746 MHz band having an antenna 
height (HAAT) less than 152 m. (500 ft.) shall afford protection to 
adjacent channel DTV stations in accordance with the values specified in 
Table E in Sec.  90.309 of this chapter, shall afford protection to co-
channel DTV stations by providing 23 dB protection to such stations' 
equivalent Grade B contour (41 dB[micro]V/m), and shall afford 
protection to co-channel and adjacent channel TV stations in accordance 
with the values specified in Table B (co-channel frequencies based on 40 
dB protection) and Table E (adjacent channel frequencies based on 0 dB 
protection) in Sec.  90.309 of this chapter. For base and fixed stations 
having an antenna height (HAAT) between 152-914 meters (500-3,000 ft.) 
the effective radiated power must be reduced below 1 kilowatt in 
accordance with the values shown in the power reduction graph in Figure 
B in Sec.  90.309 of this chapter. For heights of more than 152 m. (500 
ft.) above average terrain, the distance to the radio path horizon will 
be calculated assuming smooth earth. If the distance so determined 
equals or exceeds the distance to the hypothetical or equivalent Grade B 
contour of a co-channel TV/DTV station (i.e., it exceeds the distance 
from the appropriate Table in Sec.  90.309 of this chapter to the 
relevant TV/DTV station), an authorization will not be granted unless it 
can be shown in an engineering study (see paragraph (b)(1)(iii) of this 
section) that actual terrain considerations are such as to provide the 
desired protection at the actual Grade B contour (64 dB[micro]V/m for TV 
and 41 dB[micro]V/m for DTV stations) or unless the effective radiated 
power will be further reduced so that, assuming free space attenuation, 
the desired protection at the actual Grade B contour (64 dB[micro]V/m 
for TV and 41 dB[micro]V/m coverage contour for DTV stations) will be 
achieved. Directions for calculating powers, heights, and reduction 
curves are listed in Sec.  90.309 of this chapter for land mobile 
stations. Directions for calculating coverage contours are listed in 
Sec. Sec.  73.683 through 73.685 of this chapter for TV stations and in 
Sec.  73.625 of this chapter for DTV stations.
    (ii) Control, fixed, and mobile stations (including portables) that 
operate in the 787-788 MHz and 805-806 MHz bands and control and mobile 
stations (including portables) that operate in the 698-757 MHz and 776-
787 MHz bands are limited in height and power and therefore shall afford 
protection to co-channel and adjacent channel TV/DTV stations in the 
following manner:
    (A) For control, fixed, and mobile stations (including portables) 
that operate in the 787-788 MHz and 805-806 MHz bands and control and 
mobile stations (including portables) that operate in the 746-757 MHz 
and 776-787 MHz

[[Page 362]]

bands, co-channel protection shall be afforded in accordance with the 
values specified in Table D (co-channel frequencies based on 40 dB 
protection for TV stations and 17 dB for DTV stations) in Sec.  90.309 
of this chapter.
    (B) For control and mobile stations (including portables) that 
operate in the 698-746 MHz band, co-channel protection shall be afforded 
to TV stations in accordance with the values specified in Table D (co-
channel frequencies based on 40 dB protection) and to DTV stations by 
providing 23 dB protection to such stations' equivalent Grade B contour 
(41 dB[micro]V/m).
    (C) For control, fixed, and mobile stations (including portables) 
that operate in the 787-788 MHz and 805-806 MHz bands and control and 
mobile stations (including portables) that operate in the 698-757 MHz 
and 776-787 MHz bands, adjacent channel protection shall be afforded by 
providing a minimum distance of 8 kilometers (5 miles) from all adjacent 
channel TV/DTV station hypothetical or equivalent Grade B contours 
(adjacent channel frequencies based on 0 dB protection for TV stations 
and -23 dB for DTV stations).
    (D) Since control, fixed, and mobile stations may affect different 
TV/DTV stations than the associated base or fixed station, particular 
care must be taken by applicants/licensees to ensure that all 
appropriate TV/DTV stations are considered (e.g., a base station may be 
operating within TV Channel 62 and the mobiles within TV Channel 67, in 
which case TV Channels 61, 62, 63, 66, 67 and 68 must be protected). 
Control, fixed, and mobile stations shall keep a minimum distance of 
96.5 kilometers (60 miles) from all adjacent channel TV/DTV stations. 
Since mobiles and portables are able to move and communicate with each 
other, licensees must determine the areas where the mobiles can and 
cannot roam in order to protect the TV/DTV stations.

    Note to Sec.  27.60: The 88.5 km (55mi) Grade B service contour (64 
dB[micro]V/m) is based on a hypothetical TV station operating at an 
effective radiated power of one megawatt, a transmitting antenna height 
above average terrain of 610 meters (2000 feet) and the Commission's R-
6602 F(50,50) curves. See Sec.  73.699 of this chapter. Maximum 
facilities for TV stations operating in the UHF band are 5 megawatts 
effective radiated power at an antenna HAAT of 610 meters (2,000 feet). 
See Sec.  73.614 of this chapter. The equivalent contour for DTV 
stations is based on a 41 dB[micro]V/m signal strength and the distance 
to the F(50,90) curve. See Sec.  73.625 of this chapter.

Sec.  27.64  Protection from interference.

    Wireless Communications Service (WCS) stations operating in full 
accordance with applicable FCC rules and the terms and conditions of 
their authorizations are normally considered to be non-interfering. If 
the FCC determines, however, that interference which significantly 
interrupts or degrades a radio service is being caused, it may, after 
notice and an opportunity for a hearing, require modifications to any 
WCS station as necessary to eliminate such interference.
    (a) Failure to operate as authorized. Any licensee causing 
interference to the service of other stations by failing to operate its 
station in full accordance with its authorization and applicable FCC 
rules shall discontinue all transmissions, except those necessary for 
the immediate safety of life or property, until it can bring its station 
into full compliance with the authorization and rules.

Sec.  27.70  Information exchange.

    (a) Prior notification. Public safety licensees authorized to 
operate in the 758-775 MHz and 788-805 MHz bands may notify any licensee 
authorized to operate in the 746-757 or 776-787 MHz bands that they wish 
to receive prior notification of the activation or modification of the 
licensee's base or fixed stations in their area. Thereafter, the 746-757 
or 776-787 MHz band licensee must

[[Page 364]]

provide the following information to the public safety licensee at least 
10 business days before a new base or fixed station is activated or an 
existing base or fixed station is modified:
    (1) Location;
    (2) Effective radiated power;
    (3) Antenna height; and
    (4) Channels available for use.
    (b) Purpose of prior notification. The prior coordination of base or 
fixed stations is for informational purposes only. Public safety 
licensees are not afforded the right to accept or reject the activation 
of a proposed base or fixed station or to unilaterally require changes 
in its operating parameters. The principal purposes of notification are 
to:
    (1) Allow a public safety licensee to advise the 746-757 or 776-787 
MHz band licensee whether it believes a proposed base or fixed station 
will generate unacceptable interference;
    (2) Permit 746-757 and 776-787 MHz band licensees to make voluntary 
changes in base or fixed station parameters when a public safety 
licensee alerts them to possible interference; and,
    (3) Rapidly identify the source if interference is encountered when 
the base or fixed station is activated.

Sec.  27.72  Information sharing requirements.

    This section requires WCS licensees in the 2305-2320 MHz and 2345-
2360 MHz bands to share information regarding the location and operation 
of base and fixed stations (except fixed customer premises equipment) 
with Satellite Digital Audio Radio Service (SDARS) licensees in the 
2320-2345 MHz band. Section 25.263 of this chapter requires SDARS 
licensees in the 2320-2345 MHz band to share information regarding the 
location and operation of terrestrial repeaters with WCS licensees in 
the 2305-2320 MHz and 2345-2360 MHz bands. WCS licensees are encouraged 
to develop separate coordination agreements with SDARS licensees to 
facilitate efficient deployment of and coexistence between each service. 
To the extent the provisions of any such coordination agreement conflict 
with the requirements set forth herein, the procedures established under 
a coordination agreement will control. WCS licensees must maintain a 
copy of any coordination agreement with an SDARS licensee in their 
station files and disclose it to prospective assignees, transferees, or 
spectrum lessees and, upon request, to the Commission.
    (a) Sites and frequency selections. WCS licensees must select base 
and fixed station sites and frequencies, to the extent practicable, to 
minimize the possibility of harmful interference to operations in the 
SDARS 2320-2345 MHz band.
    (b) Prior notice periods. WCS licensees that intend to operate a 
base or fixed station must, before commencing such operation, provide 10 
business days prior notice to all SDARS licensees. WCS licensees that 
intend to modify an existing station must, before commencing such 
modified operation, provide 5 business days prior notice to all SDARS 
licensees. For the purposes of this section, a business day is defined 
by Sec.  1.4(e)(2) of this chapter.
    (1) For modifications other than changes in location, a licensee may 
provide notice within 24 hours after the modified operation if the 
modification does not result in a predicted increase of the power flux 
density (PFD) at ground level by more than 1 dB since the last advance 
notice was given. If a demonstration is made by the SDARS licensee that 
such modifications may cause harmful interference to SDARS receivers, 
WCS licensees will be required to provide notice 5 business days in 
advance of additional station modifications.
    (2) WCS base and fixed stations operating below 2 watts equivalent 
isotropically radiated power (EIRP) are exempt from the notice 
requirements set forth in this paragraph.
    (3) WCS and SDARS licensees may enter into agreements regarding 
alternative notification procedures.
    (c) Contents of notice. (1) Notification must be written (e.g., 
certified letter, fax, or e-mail) and include the licensee's name, and 
the name, address, and telephone number of its coordination 
representative, unless the SDARS licensee and all potentially affected 
WCS licensees reach a mutual agreement to

[[Page 365]]

provide notification by some other means. WCS licensees and SDARS 
licensees may establish such a mutually agreeable alternative 
notification mechanism without prior Commission approval, provided that 
they comply with all other requirements of this section.
    (2) Regardless of the notification method, it must specify relevant 
technical details, including, at a minimum:
    (i) The coordinates of the proposed base or fixed stations to an 
accuracy of no less than 1 second latitude and 
longitude;
    (ii) The proposed operating power(s), frequency band(s), and 
emission(s);
    (iii) The antenna center height above ground and ground elevation 
above mean sea level, both to an accuracy of no less than 1 meter;
    (iv) The antenna gain pattern(s) in the azimuth and elevation planes 
that include the peak of the main beam; and
    (v) The antenna downtilt angle(s).
    (3) A WCS licensee operating base or fixed stations must maintain an 
accurate and up-to-date inventory of its stations, including the 
information set forth in Sec.  27.72(c)(2), which shall be available 
upon request by the Commission.
    (d) Calculation of notice period. Notice periods are calculated from 
the date of receipt by the licensee being notified. If notification is 
by mail, the date of receipt is evidenced by the return receipt on 
certified mail. If notification is by fax, the date of receipt is 
evidenced by the notifying party's fax transmission confirmation log. If 
notification is by e-mail, the date of receipt is evidenced by a return 
e-mail receipt. If the SDARS licensee and all potentially affected WCS 
licensees reach a mutual agreement to provide notification by some other 
means, that agreement must specify the method for determining the 
beginning of the notice period.
    (e) Duty to cooperate. WCS licensees must cooperate in good faith in 
the selection and use of new station sites and new frequencies to reduce 
interference and make the most effective use of the authorized 
facilities. WCS licensees should provide SDARS licensees as much lead 
time as practicable to provide ample time to conduct analyses and 
opportunity for prudent base station site selection prior to WCS 
licensees entering into real estate and tower leasing or purchasing 
agreements. WCS licensees must have sufficient operational flexibility 
in their network design to implement one or more technical solutions to 
remedy harmful interference. Licensees of stations suffering or causing 
harmful interference, as defined in Sec.  27.64(d), must cooperate in 
good faith and resolve such problems by mutually satisfactory 
arrangements. If the licensees are unable to do so, the Wireless 
Telecommunications Bureau, in consultation with the Office of 
Engineering and Technology and the Space Bureau, will consider the 
actions taken by the parties to mitigate the risk of and remedy any 
alleged interference. In determining the appropriate action, the Bureau 
will take into account the nature and extent of the interference and act 
promptly to remedy the interference. The Bureau may impose restrictions 
on WCS licensees, including specifying the transmitter power, antenna 
height, or other technical or operational measures to remedy the 
interference, and will take into account previous measures by the 
licensees to mitigate the risk of interference.

    (b) WCS licensees operating base and fixed stations in the 2305-2320 
MHz band must, prior to operation of such stations, achieve a mutually 
satisfactory coordination agreement with the National Aeronautics and 
Space Administration (NASA) within 145 kilometers of the Goldstone, CA 
earth station site (35[deg]25[min]33[sec] N, 116[deg]53[min]23[sec] W).
    (c) After base or fixed station operations commence, upon receipt of 
a complaint of harmful interference, the WCS licensee(s) receiving the 
complaint, no matter the distance from the NASA Goldstone, CA earth 
station or from an AMT site, operating in the 2305-2320 or 2345-2360 MHz 
bands, respectively, shall take all practicable steps to immediately 
eliminate the interference.
    (d) Duty to cooperate. WCS licensees, AFTRCC, and NASA must 
cooperate in good faith in the coordination and deployment of new 
facilities. WCS licensees must also cooperate in good faith in the 
selection and use of new station sites and new frequencies when within 
radio line of site of AMT receiver facilities to reduce the risk of 
harmful interference and make the most effective use of the authorized 
facilities. Licensees of stations suffering or causing harmful 
interference must cooperate in good faith and resolve such problems by 
mutually satisfactory arrangements. If the licensees are unable to do 
so, the Wireless Telecommunications Bureau, in consultation with the 
Office of Engineering and Technology and the National Telecommunications 
and Information Administration may impose restrictions including 
specifying the transmitter power, antenna height, or area or hours of 
operation of the stations.

     Subpart E_Application, Licensing, and Processing Rules for WCS



Sec.  27.301  [Reserved]



Sec.  27.302  Eligibility.

    (a) General. Authorizations will be granted upon proper application 
if:
    (1) The applicant is qualified under the applicable laws and the 
regulations, policies and decisions issued under those laws, including 
Sec.  27.12;
    (2) There are frequencies available to provide satisfactory service; 
and
    (3) The public interest, convenience or necessity would be served by 
a grant.
    (b) Alien Ownership. A WCS authorization may not be granted to or 
held by an entity not meeting the requirements of section 310 of the 
Communications Act of 1934, as amended, 47 U.S.C. section 310 insofar as 
applicable to the particular service in question.



Sec.  27.303  Upper 700 MHz commercial and public safety coordination zone.

    (a) General. CMRS operators are required, prior to commencing 
operations on fixed or base station transmitters on the 776-787 MHz band 
that are located within 500 meters of existing or planned public safety 
base station receivers, to submit a description of their proposed 
facility to a Commission-approved public safety coordinator.
    (i) The frequency or frequencies on which the facility will operate;
    (ii) Antenna location and height;
    (iii) Type of emission;
    (iv) Effective radiated power;
    (v) A description of the area served and the operator's name.
    (2) It is the CMRS operator's responsibility to determine whether 
referral is required for stations constructed in its area of license. 
Public safety base stations are considered ``planned'' when public 
safety operators have notified, or initiated coordination with, a 
Commission-approved public safety coordinator.
    (b) CMRS operators must wait at least 10 business days after 
submission of the required description before commencing operations on 
the referenced facility, or implementing modifications to an existing 
facility.
    (c) The potential for harmful interference between the CMRS and 
public safety facilities will be evaluated by the public safety 
coordinator.
    (1) With regard to existing public safety facilities, the 
coordinator's determination to disapprove a proposed CMRS facility (or 
modification) to be located within 500 meters of the public safety 
facilities will be presumed correct, but the CMRS operator may seek 
Commission review of such determinations. Pending Commission review, the 
CMRS operator will not activate the facility or implement proposed 
modifications.
    (2) With regard to proposed public safety facilities, the 
coordinator's determination to disapprove a proposed CMRS facility (or 
modification) to be located within 500 meters of the public safety 
facilities will be presumed correct, but the CMRS operator may seek 
Commission review and, pending completion of review, operate the 
facility during construction of the public safety facilities. If 
coordination or Commission review has not been completed when the public 
safety facilities are ready to operate, the CMRS operator must cease 
operations pending completion of coordination or Commission review. Such 
interim operation of the CMRS facility within the coordination zone (or 
implementation of modifications) will not be relied on by the Commission 
in its subsequent review and determination of measures necessary to 
control interference, including relocation or modification of the CMRS 
facility.
    (d) If, in the event of harmful interference between facilities 
located within 500 meters proximity, the parties are unable, with the 
involvement of the coordinator, to resolve the problem by mutually 
satisfactory arrangements, the Commission may impose restrictions on the 
operations of any of the parties involved.

Reimbursement Obligation of Licensees at 1915-1920 MHz and 1995-2000 MHz



Sec.  27.1021  Reimbursement obligation of licensees at 1915-1920 MHz.

    A licensee in the 1915-1920 MHz band (Lower H Block) shall, within 
30 days of grant of its long-form application, reimburse 25 percent of 
the total relocation costs incurred by UTAM, Inc. for relocating and 
clearing incumbent Fixed Microwave Service (FS) licensees from the 1910-
1930 MHz band on a pro rata shared basis with other Lower H Block 
licensees as set forth in paragraphs (a) through (e) of this section.
    (a)(1) If Lower H Block licenses granted as a result of the first 
auction for this spectrum cover, collectively, at least forty (40) 
percent of the nation's population, the amount owed to UTAM, Inc. by 
each individual Lower H Block licensee (reimbursement amount owed or RN) 
will be determined by dividing the gross winning bid (GWB) for each 
individual Lower H Block license (i.e., an Economic Area (EA)) by the 
sum of the gross winning bids for all Lower H Block licenses for which 
there is a winning bid in the first auction, and then multiplying by 
$12,629,857.

RN = (EA GWB / Sum of GWBs) x $12,629,857.00

    (2) Except as provided in paragraphs (b) and (c) of this section, a 
licensee that obtains a license for a market in which no license is 
granted as a result of the first Lower H Block auction will not have a 
reimbursement obligation to UTAM, Inc.
    (b) If Lower H Block licenses granted as a result of the first 
auction for this spectrum cover, collectively, less than forty (40) 
percent of the nation's population, then the pro rata amount that the 
licensee of an individual Lower H Block license must reimburse UTAM, 
Inc. shall be calculated by dividing the population of the individual EA 
by the total U.S. population, and then multiplying by $12,629,857. In 
this event, the same population data, e.g., 2010, used to calculate the 
RNs for Lower H Block licenses granted as a result of the first auction 
will apply to subsequent auctions of Lower H Block licenses that were 
not granted as a result of an earlier auction of Lower H Block licenses.

RN = (EA POP / U.S. POP) x $12,629,857.00

    (c) A winning bidder of a Lower H Block license that is not granted 
a license for any reason will be deemed to have triggered a 
reimbursement obligation to UTAM, Inc. This obligation will be owed to 
UTAM, Inc. by the licensee acquiring the Lower H Block license through a 
subsequent auction. The amount owed by the licensee acquiring the Lower 
H Block license at such auction will be the RN calculated for the EA 
license based on the first auction (calculated under paragraphs (a) or 
(b), as applicable, of this section).
    (d) For purposes of compliance with this section, licensees should 
determine population based on 2010 U.S. Census Data or such other data 
or measurements that the Wireless Telecommunications Bureau proposes and 
adopts under the notice and comment process for the auction procedures.
    (e) A payment obligation owed by a Lower H Block licensees under 
this section shall be made within thirty (30) days of the grant of the 
license (i.e., grant of the long form application).



Sec.  27.1031  Reimbursement obligation of licensees at 1995-2000 MHz.

    A licensee in the 1995-2000 MHz band (Upper H Block) shall, within 
30 days of grant of its long-form application, reimburse one-seventh of 
the eligible expenses incurred by Sprint Nextel, Inc. (Sprint) for 
relocating and clearing Broadcast Auxiliary Service (BAS),

[[Page 375]]

Cable Television Relay Service (CARS), and Local Television Transmission 
Service (LTTS) incumbents from the 1990-2025 MHz band, on a pro rata 
shared basis with other Upper H Block licensees as set forth in 
paragraphs (a) through (e) of this section.
    (a)(1) If Upper H Block licenses granted as a result of the first 
auction for this spectrum cover, collectively, at least forty (40) 
percent of the nation's population, the amount owed to Sprint by the 
winning bidder of each individual Upper H Block license granted as a 
result of the first auction will be determined by dividing the gross 
winning bid (GWB) for each individual Upper H Block license (i.e., an 
Economic Area (EA)) by the sum of the gross winning bids for all Upper H 
Block licenses for which there is a winning bid in the first auction, 
and then multiplying by $94,875,516.

RN = (EA GWB / Sum of GWBs) x $94,875,516

    (2) Except as provided in paragraphs (b) and (c) of this section, a 
licensee that obtains a license for a market in which no license was 
granted as a result of the first Upper H Block auction will not have a 
reimbursement obligation to Sprint.
    (b) If Upper H Block licenses granted as a result of the first 
auction for this spectrum cover, collectively, less than forty (40) 
percent of the nation's population, then the amount that the licensee of 
an individual Upper H Block license must reimburse Sprint shall be 
calculated by dividing the population of the individual EA by the total 
U.S. population, and then multiplying by $94,875,516. In this event, the 
same population data, e.g., 2010, used to calculate the RNs for Upper H 
Block licenses granted as a result of the first auction will apply to 
subsequent auctions of Upper H Block licenses that were not granted as a 
result of an earlier auction of Upper H Block licenses.

RN = (EA POP / U.S. POP) x $94,875,516

    (c) A winning bidder of an Upper H Block license that is not granted 
a license for any reason will be deemed to have triggered a 
reimbursement obligation to Sprint. This obligation will be owed to 
Sprint by the licensee acquiring the Upper H Block license through a 
subsequent auction. The amount owed by the licensee acquiring the EA 
license at such auction will be based on the RN calculated for the EA 
license based on the first auction (calculated under paragraphs (a) or 
(b), as applicable, of this section).
    (d) For purposes of compliance with this section, licensees should 
determine population based on 2010 U.S. Census Data or such other data 
or measurements that the Wireless Telecommunications Bureau proposes and 
adopts under the notice and comment process for the auction procedures.
    (e) A payment obligation owed by a Upper H Block licensees under 
this section shall be made within thirty (30) days of the grant of the 
license (i.e., grant of the long form application).



Sec.  27.1041  Termination of cost-sharing obligations.

    (a) The cost-sharing obligation adopted in this subpart for the 
Lower H Block and for the Upper H Block will sunset ten years after the 
first license is issued in the respective band.
    (b) A Lower H Block licensee and an Upper H Block licensee must 
satisfy in full its payment obligations under this subpart K within 
thirty days of the grant of its long-form application. The failure to 
timely satisfy a payment obligation in full prior to the applicable 
sunset date will not terminate the debt owed or a party's right to

Sec.  27.1133  Protection of part 74 and part 78 operations.

    AWS operators must protect previously licensed Broadcast Auxiliary 
Service (BAS) or Cable Television Radio Service (CARS) operations in the 
adjacent 2025-2110 MHz band. In satisfying this requirement AWS 
licensees must, before constructing and operating any base or fixed 
station, determine the location and licensee of all BAS or CARS stations 
authorized in their area of operation, and coordinate their planned 
stations with those licensees. In the event that mutually satisfactory 
coordination agreements cannot be reached, licensees may seek the 
assistance of the Commission, and the Commission may, at its discretion, 
impose requirements on one or both parties.



Sec.  27.1134  Protection of Federal Government operations.

    (a) Protection of Department of Defense operations in the 1710-1755 
MHz band. The Department of Defense (DoD) operates communications 
systems in the 1710-1755 MHz band at 16 protected facilities, 
nationwide. AWS licensees must accept any interference received from 
these facilities and must protect the facilities from interference. AWS 
licensees shall protect the facilities from interference by restricting 
the operation of their base and fixed stations from any locations that 
could potentially permit AWS mobile, fixed, and portable stations 
transmitting in the 1710-1755 MHz band to cause interference to 
government operations within the radii of operation of the 16 facilities 
(the radii of operation of each facility is indicated in the third 
column of Table 1 immediately following paragraph (a)(3) of this 
section). In addition, AWS licensees shall be required to coordinate any 
operations that could permit mobile, fixed, and portable stations to 
operate in the specified areas of the 16 facilities, as defined in 
paragraph (a)(3) of this section. Protection of these facilities in this 
manner shall take place under the following conditions:
    (1) At the Yuma, Arizona and Cherry Point, North Carolina 
facilities, all operations shall be protected indefinitely.
    (2) At the remaining 14 facilities, airborne and military test range 
operations shall be protected until such time as these systems are 
relocated to other spectrum, and precision guided munitions (PGM) 
operations shall be protected until such time as these systems are 
relocated to other spectrum or until PGM inventory at each facility is 
exhausted, whichever occurs first.

[[Page 378]]

    (3) AWS licensees whose transmit operations in the 1710-1755 MHz 
band consist of fixed or mobile operations with nominal transmit EIRP 
values of 100 mW or less and antenna heights of 1.6 meters above ground 
or less shall coordinate their services around the 16 sites at the 
distance specified in row a. of Table 2. AWS licensees whose transmit 
operations in the 1710-1755 MHz band consist of fixed or mobile 
operations with nominal transmit EIRP values of 1 W or less and antenna 
heights of 10 meters above ground or less shall coordinate their 
services around the 16 sites at the distance specified in row b. of 
Table 2. These coordination distances shall be measured from the edge of 
the operational distances indicated in the third column of Table 1, and 
coordination with each affected DoD facility shall be accomplished 
through the Commander of the facility.

    (b) Protection of non-DoD operations in the 1710-1755 MHz and 1755-
1761 MHz bands. Until such time as non-DoD systems operating in the 
1710-1755 MHz and 1755-1761 MHz bands are relocated to other spectrum, 
AWS licensees shall protect such systems by satisfying the appropriate 
provisions of TIA Telecommunications Systems Bulletin 10-F, 
``Interference Criteria for Microwave Systems,'' May, 1994 (TSB 10-F).
    (c) Protection of Federal operations in the 1675-1710 MHz band--(1) 
27 Protection Zones. Within 27 Protection Zones, prior to operating a 
base station that enables mobile or portable stations to transmit in the 
1695-1710 MHz band, licensees must successfully coordinate such base 
station operations with Federal Government entities operating 
meteorological satellite Earth-station receivers in the 1675-1710 MHz 
band. See 47 CFR 2.106, footnote US 88, for the 27 Protection Zones and 
other details.
    (2) Operation outside of 27 Protection Zones. Non-Federal 
operations, for mobile and portable stations operating at a maximum EIRP 
of 20 dBm, are permitted outside of the protection zones without 
coordination. All non-Federal operations for mobile and portables 
operating at a maximum EIRP of greater than 20 dBm and up to 30 dBm must 
be coordinated nationwide. All such operations may not cause harmful 
interference to the Federal operations protected in 47 CFR 2.106, 
footnote US 88.

[[Page 379]]

    (3) Interference. If protected Federal operations receive harmful 
interference from AWS operations in the 1695-1710 MHz band, an AWS 
licensee must, upon notification, modify its operations and/or technical 
parameters as necessary to eliminate the interference.
    (4) Point of contact. AWS licensees in the 1695-1710 MHz band must 
provide and maintain a point of contact at all times so that immediate 
contact can be made should interference against protected Federal sites 
occur.
    (5) Coordination procedures. Federal use of the radio spectrum is 
generally governed by the National Telecommunications and Information 
Administration (NTIA) while non-Federal use is governed by the 
Commission. As such, any guidance or details concerning Federal/non-
Federal coordination must be issued jointly by NTIA and the Commission. 
The Commission may jointly issue with NTIA one or more public notices 
with guidance or details concerning the coordination procedures for the 
1695-1710 MHz band.
    (6) Requirements for licensees operating in the 1710-1755 MHz band. 
AWS licensees operating fixed stations in the 1710-1755 MHz band, if 
notified that such stations are causing interference to radiosonde 
receivers operating in the Meteorological Aids Service in the 1675-1700 
MHz band or a meteorological-satellite earth receiver operating in the 
Meteorological-Satellite Service in the 1675-1710 MHz band, shall be 
required to modify the stations' location and/or technical parameters as 
necessary to eliminate the interference.
    (d) Recognition of NASA Goldstone facility operations in the 2110-
2120 MHz band. The National Aeronautics and Space Administration (NASA) 
operates the Deep Space Network (DSN) in the 2110-2120 MHz band at 
Goldstone, California (see Table 3). NASA will continue its operations 
of high power transmitters (nominal EIRP of 105.5 dBW with EIRP up to 
119.5 dBW used under emergency conditions) in this band at this 
location. AWS licensees must accept any interference received from the 
Goldstone DSN facility in this band.

    (e) Protection of Federal operations in the 2200-2290 MHz band--(1) 
Default emission limits. Except as provided in paragraph (e)(2) of this 
section, the following default out-of-band emissions limits shall apply 
for AWS-4 operations in the 2180-2200 MHz band.
    (i) For these AWS-4 operations, the power of any emissions on all 
frequencies between 2200 and 2290 MHz shall not exceed an EIRP of -100.6 
dBW/4 kHz.
    (ii) No AWS-4 base station operating in the 2180-2200 MHz band shall 
be located less than 820 meters from a U.S. Earth Station facility 
operating in the 2200-2290 MHz band.
    (2) Agreements between AWS-4 operators and Federal government 
entities. The out-of-band emissions limits in paragraph (e)(1) of this 
section may be modified by the private contractual agreement of 
licensees of AWS-4 operating authority and Federal government entities 
operating in the 2200-2290 MHz band. Such agreement shall be transmitted 
to the Commission by the National Telecommunications and Information 
Administration (NTIA) of the U.S. Department of Commerce. A licensee of 
AWS-4 operating authority who is a party to such an agreement must 
maintain a copy of the agreement in its station files and disclose it, 
upon request, to prospective AWS-4 assignees, transferees, or spectrum 
lessees, to Federal operators, and to the Commission.
    (f) Protection of Federal operations in the 1755-1780 MHz band. The 
Federal Government operates communications

[[Page 380]]

systems in the 1755-1780 MHz band. Certain systems are expected to 
continue to operate in the band indefinitely. All other operations will 
be relocating to other frequencies or otherwise cease operations in the 
1755-1780 MHz band in accordance with 47 CFR part 301. Until such a time 
as Federal operations in the 1755-1780 MHz bands vacate this spectrum, 
AWS licensees shall protect such systems and must accept any 
interference received from these Federal operations. See 47 CFR 2.106, 
footnote US 91, for details. AWS licensees must successfully coordinate 
proposed operations with all Federal incumbents prior to operation as 
follows:
    (1) Protection Zone(s). A protection zone is established for each 
Federal operation pursuant to 47 CFR 2.106, footnote US 91. Unless 
otherwise specified in later Commission actions, the default protection 
zone is nationwide. A base station which enables mobile or portable 
stations to transmit in the 1755-1780 MHz band may not operate within 
the Protection Zone(s) of a Federal operation until the licensee 
successfully coordinates such base station operations with Federal 
Government entities as follows depending on the type of Federal 
incumbent authorization:
    (i) Federal US&P Assignments. Each AWS licensee must coordinate with 
each Federal agency that has U.S. and Possessions (US&P) authority prior 
to its first operations in its licensed area to reach a coordination 
arrangement with each US&P agency on an operator-to-operator basis. 
(Agencies with U.S. and Possessions (US&P) authority do not operate 
nationwide and may be able to share, prior to relocation, in some 
areas.)
    (ii) Other Federal Assignments. Each AWS licensee must successfully 
coordinate all base station operations within a Protection Zone with the 
Federal incumbents. The default requirement is a nationwide coordination 
zone with possible revisions to the Protection Zone and other details to 
be announced in a Joint FCC/NTIA public notice.
    (2) Interference. If protected Federal operations receive harmful 
interference from AWS operations in the 1755-1780 MHz band, an AWS 
licensee must, upon notification, modify its operations and/or technical 
parameters as necessary to eliminate the interference.
    (3) Point of contact. AWS licensees in the 1755-1780 MHz band must 
provide and maintain a point of contact at all times so that immediate 
contact can be made should interference against protected Federal 
operations occur.
    (4) Coordination procedures. Federal use of the radio spectrum is 
generally governed by the National Telecommunications and Information 
Administration (NTIA) while non-Federal use is governed by the 
Commission. As such, any guidance or details concerning Federal/non-
Federal coordination must be issued jointly by NTIA and the Commission. 
The Commission may jointly issue with NTIA one or more public notices 
with guidance or details concerning the coordination procedures for the 
1755-1780 MHz band.

Sec.  27.1135  Protection of non-Federal Government Meteorological-Satellite
operations.

    AWS licensees operating fixed stations in the 1710-1755 MHz band, if 
notified that such stations are causing interference to meteorological-
satellite earth receivers operating in the Meteorological-Satellite 
Service in the 1675-1710 MHz band, shall be required to modify the 
stations' location and/or technical parameters as necessary to eliminate 
the interference.



Sec.  27.1136  Protection of mobile satellite services in the 2000-2020 MHz
and 2180-2200 MHz bands.

    An AWS licensee of the 2000-2020 MHz and 2180-2200 MHz bands must 
accept any interference received from duly authorized mobile satellite 
service operations in these bands. Any such AWS licensees must protect 
mobile satellite service operations in these bands from harmful 
interference.

Cost-Sharing Policies Governing Microwave Relocation From the 2110-2150 
                       MHz and 2160-2200 MHz Bands

    Source: Sections 27.1160 through 27.1174 appear at 71 FR 29835, May 
24, 2006, unless otherwise noted.



Sec.  27.1160  Cost-sharing requirements for AWS.

    Frequencies in the 2110-2150 MHz and 2160-2200 MHz bands listed in 
Sec.  101.147 of this chapter have been reallocated from Fixed Microwave 
Services (FMS) to use by AWS (as reflected in Sec.  2.106 of this 
chapter). In accordance with procedures specified in Sec.  22.602 and 
Sec. Sec.  101.69 through 101.82 of this chapter, AWS entities are 
required to relocate the existing microwave licensees in these bands if 
interference to the existing microwave licensee would occur. All AWS 
entities that benefit from the clearance of this spectrum by other AWS 
entities or by a voluntarily relocating microwave incumbent must 
contribute to such relocation costs. AWS entities may satisfy their 
reimbursement requirement by entering into private cost-sharing 
agreements or agreeing to terms other than those specified in Sec.  
27.1164. However, AWS entities are required to reimburse other AWS 
entities or voluntarily relocating microwave incumbents that incur 
relocation costs and are not parties to the alternative agreement. In 
addition, parties to a private cost-sharing agreement may seek 
reimbursement through the clearinghouse (as discussed in Sec.  27.1162) 
from AWS entities or other Emerging Technologies (ET) entities, 
including Mobile Satellite Service (MSS) operators (for Ancillary 
Terrestrial Component (ATC) base stations), that are not parties to the 
agreement. The cost-sharing plan is in effect during all phases of 
microwave relocation specified in Sec. Sec.  22.602 and 101.69 of this 
chapter. If an AWS licensee enters into a spectrum leasing arrangement 
(as set forth in part 1, subpart X of this chapter) and the spectrum 
lessee triggers a cost-sharing obligation, the licensee is the AWS 
entity responsible for satisfying the cost-sharing obligations under 
Sec. Sec.  27.1160-27.1174.

[71 FR 29835, May 24, 2006, as amended at 78 FR 8270, Feb. 5, 2013]



Sec.  27.1162  Administration of the Cost-Sharing Plan.

    The Wireless Telecommunications Bureau, under delegated authority, 
will select one or more entities to operate as a neutral, not-for-profit 
clearinghouse(s). This clearinghouse(s) will administer the cost-sharing 
plan by, inter alia, determining the cost-sharing obligation of AWS and 
other ET entities for the relocation of FMS incumbents from the 2110-
2150 MHz and 2160-2200 MHz bands. The clearinghouse filing requirements 
(see Sec. Sec.  27.1166(a), 27.1170) will not take effect until an 
administrator is selected.



Sec.  27.1164  The cost-sharing formula.

    An AWS relocator who relocates an interfering microwave link, i.e., 
one that is in all or part of its market area and in all or part of its 
frequency band or a voluntarily relocating microwave incumbent, is 
entitled to pro rata reimbursement based on the following formula:

[GRAPHIC] [TIFF OMITTED] TR24MY06.007

    (a) RN equals the amount of reimbursement.
    (b) C equals the actual cost of relocating the link(s). Actual 
relocation costs include, but are not limited to, such items as: Radio 
terminal equipment (TX and/or RX--antenna, necessary feed lines, MUX/
Modems); towers and/or modifications; back-up

[[Page 382]]

power equipment; monitoring or control equipment; engineering costs 
(design/path survey); installation; systems testing; FCC filing costs; 
site acquisition and civil works; zoning costs; training; disposal of 
old equipment; test equipment (vendor required); spare equipment; 
project management; prior coordination notification under Sec.  
101.103(d) of this chapter; site lease renegotiation; required antenna 
upgrades for interference control; power plant upgrade (if required); 
electrical grounding systems; Heating Ventilation and Air Conditioning 
(HVAC) (if required); alternate transport equipment; and leased 
facilities. Increased recurring costs represent part of the actual cost 
of relocation and, even if the compensation to the incumbent is in the 
form of a commitment to pay five years of charges, the AWS or MSS/ATC 
relocator is entitled to seek immediate reimbursement of the lump sum 
amount based on present value using current interest rates, provided it 
has entered into a legally binding agreement to pay the charges. C also 
includes voluntarily relocating microwave incumbent's independent third 
party appraisal of its compensable relocation costs and incumbent 
transaction expenses that are directly attributable to the relocation, 
subject to a cap of two percent of the ``hard'' costs involved. Hard 
costs are defined as the actual costs associated with providing a 
replacement system, such as equipment and engineering expenses. C may 
not exceed $250,000 per paired link, with an additional $150,000 
permitted if a new or modified tower is required.
    (c) N equals the number of AWS and MSS/ATC entities that have 
triggered a cost-sharing obligation. For the AWS relocator, N = 1. For 
the next AWS entity triggering a cost-sharing obligation, N = 2, and so 
on. In the case of a voluntarily relocating microwave incumbent, N = 1 
for the first AWS entity triggering a cost-sharing obligation. For the 
next AWS or MSS/ATC entity triggering a cost-sharing obligation, N = 2, 
and so on.
    (d) Tm equals the number of months that have elapsed between the 
month the AWS or MSS/ATC relocator or voluntarily relocating microwave 
incumbent obtains reimbursement rights for the link and the month in 
which an AWS entity triggers a cost-sharing obligation. An AWS or MSS/
ATC relocator obtains reimbursement rights for the link on the date that 
it signs a relocation agreement with a microwave incumbent. A 
voluntarily relocating microwave incumbent obtains reimbursement rights 
for the link on the date that the incumbent notifies the Commission that 
it intends to discontinue, or has discontinued, the use of the link, 
pursuant to Sec.  101.305 of the Commission's rules.



Sec.  27.1166  Reimbursement under the Cost-Sharing Plan.

    (a) Registration of reimbursement rights. Claims for reimbursement 
under the cost-sharing plan are limited to relocation expenses incurred 
on or after the date when the first AWS license is issued in the 
relevant AWS band (start date). If a clearinghouse is not selected by 
that date (see Sec.  27.1162) claims for reimbursement (see Sec.  
27.1166) and notices of operation (see Sec.  27.1170) for activities 
that occurred after the start date but prior to the clearinghouse 
selection must be submitted to the clearinghouse within 30 calendar days 
of the selection date.
    (1) To obtain reimbursement, an AWS relocator must submit 
documentation of the relocation agreement to the clearinghouse within 30 
calendar days of the date a relocation agreement is signed with an 
incumbent. In the case of involuntary relocation, an AWS relocator must 
submit documentation of the relocated system within 30 calendar days 
after the end of the relocation.
    (2) To obtain reimbursement, a voluntarily relocating microwave 
incumbent must submit documentation of the relocation of the link to the 
clearinghouse within 30 calendar days of the date that the incumbent 
notifies the Commission that it intends to discontinue, or has 
discontinued, the use of the link, pursuant to Sec.  101.305 of the 
Commission's rules.
    (b) Documentation of expenses. Once relocation occurs, the AWS 
relocator, or the voluntarily relocating microwave incumbent, must 
submit documentation itemizing the amount spent for items specifically 
listed in

[[Page 383]]

Sec.  27.1164(b), as well as any reimbursable items not specifically 
listed in Sec.  27.1164(b) that are directly attributable to actual 
relocation costs. Specifically, the AWS relocator, or the voluntarily 
relocating microwave incumbent must submit, in the first instance, only 
the uniform cost data requested by the clearinghouse along with a copy, 
without redaction, of either the relocation agreement, if any, or the 
third party appraisal described in (b)(1) of this section, if relocation 
was undertaken by the microwave incumbent. AWS relocators and 
voluntarily relocating microwave incumbents must maintain documentation 
of cost-related issues until the applicable sunset date and provide such 
documentation upon request, to the clearinghouse, the Commission, or 
entrants that trigger a cost-sharing obligation. If an AWS relocator 
pays a microwave incumbent a monetary sum to relocate its own 
facilities, the AWS relocator must estimate the costs associated with 
relocating the incumbent by itemizing the anticipated cost for items 
listed in Sec.  27.1164(b). If the sum paid to the incumbent cannot be 
accounted for, the remaining amount is not eligible for reimbursement.
    (1) Third party appraisal. The voluntarily relocating microwave 
incumbent, must also submit an independent third party appraisal of its 
compensable relocation costs. The appraisal should be based on the 
actual cost of replacing the incumbent's system with comparable 
facilities and should exclude the cost of any equipment upgrades or 
items outside the scope of Sec.  27.1164(b).
    (2) Identification of links. The AWS relocator or the voluntarily 
relocating microwave incumbent must identify the particular link 
associated with appropriate expenses (i.e., costs may not be averaged 
over numerous links). Where the AWS relocator or voluntarily relocating 
microwave incumbent relocates both paths of a paired channel microwave 
link (e.g., 2110-2130 MHz with 2160-2180 MHz and 2130-2150 MHz with 
2180-2200 MHz), the AWS relocator or voluntarily relocating microwave 
incumbent must identify the expenses associated with each paired 
microwave link.
    (c) Full Reimbursement. An AWS relocator who relocates a microwave 
link that is either fully outside its market area or its licensed 
frequency band may seek full reimbursement through the clearinghouse of 
compensable costs, up to the reimbursement cap as defined in Sec.  
27.1164(b). Such reimbursement will not be subject to depreciation under 
the cost-sharing formula.
    (d) Good Faith Requirement. New entrants and incumbent licensees are 
expected to act in good faith in satisfying the cost-sharing obligations 
under Sec. Sec.  27.1160 through 27.1174. The requirement to act in good 
faith extends to, but is not limited to, the preparation and submission 
of the documentation required in paragraph (b) of this section.
    (e) MSS Participation in the Clearinghouse. MSS operators are not 
required to submit reimbursements to the clearinghouse for links 
relocated due to interference from MSS space-to-Earth downlink 
operations, but may elect to do so, in which case the MSS operator must 
identify the reimbursement claim as such and follow the applicable 
procedures governing reimbursement in part 27. MSS reimbursement rights 
and cost-sharing obligations for space-to-Earth downlink operations are 
governed by Sec.  101.82 of this chapter.
    (f) Reimbursement for Self-relocating FMS links in the 2130-2150 MHz 
and 2180-2200 MHz bands. Where a voluntarily relocating microwave 
incumbent relocates a paired microwave link with paths in the 2130-2150 
MHz and 2180-2200 MHz bands, it may not seek reimbursement from MSS 
operators, but is entitled to reimbursement from the first AWS 
beneficiary for its actual costs for relocating the paired link, subject 
to the reimbursement cap in Sec.  27.1164(b). This amount is subject to 
depreciation as specified in Sec.  27.1164(b). An AWS licensee who is 
obligated to reimburse relocation costs under this rule is entitled to 
obtain reimbursement from other AWS beneficiaries in accordance with 
Sec. Sec.  27.1164 and 27.1168. For purposes of applying the cost-
sharing formula relative to other AWS licensees that benefit from the 
self-relocation, depreciation shall run from the date on which the 
clearinghouse issues the notice of an obligation to reimburse the

[[Page 384]]

voluntarily relocating microwave incumbent.

[71 FR 29835, May 24, 2006, as amended at 78 FR 8270, Jan. 5, 2013]



Sec.  27.1168  Triggering a Reimbursement Obligation.

    (a) The clearinghouse will apply the following test to determine 
when an AWS entity has triggered a cost-sharing obligation and therefore 
must pay an AWS relocator, MSS relocator, or a voluntarily relocating 
microwave incumbent in accordance with the formula detailed in Sec.  
27.1164:
    (1) All or part of the relocated microwave link was initially co-
channel with the licensed AWS band(s) of the AWS entity or the selected 
assignment of the MSS operator that seeks and obtains ATC authority (see 
Sec.  25.149(a)(2)(i) of this chapter);
    (2) An AWS relocator, MSS relocator or a voluntarily relocating 
microwave incumbent has paid the relocation costs of the microwave 
incumbent; and
    (3) The AWS or MSS entity is operating or preparing to turn on a 
fixed base station at commercial power and the fixed base station is 
located within a rectangle (Proximity Threshold) described as follows:
    (i) The length of the rectangle shall be x where x is a line 
extending through both nodes of the microwave link to a distance of 48 
kilometers (30 miles) beyond each node. The width of the rectangle shall 
be y where y is a line perpendicular to x and extending for a distance 
of 24 kilometers (15 miles) on both sides of x. Thus, the rectangle is 
represented as follows:

[GRAPHIC] [TIFF OMITTED] TR24MY06.008

    (ii) If the application of the Proximity Threshold Test indicates 
that a reimbursement obligation exists, the clearinghouse will calculate 
the reimbursement amount in accordance with the cost-sharing formula and 
notify the AWS entity of the total amount of its reimbursement 
obligation.
    (b) Once a reimbursement obligation is triggered, the AWS entity may 
not avoid paying its cost-sharing obligation by deconstructing or 
modifying its facilities.

[71 FR 29835, May 24, 2006, as amended at 78 FR 8271, Jan. 5, 2013]



Sec.  27.1170  Payment issues.

    Prior to initiating operations for a newly constructed site or 
modified existing site, an AWS entity is required to file a notice 
containing site-specific

[[Page 385]]

data with the clearinghouse. The notice regarding the new or modified 
site must provide a detailed description of the proposed site's spectral 
frequency use and geographic location, including but not limited to the 
applicant's name and address, the name of the transmitting base station, 
the geographic coordinates corresponding to that base station, the 
frequencies and polarizations to be added, changed or deleted, and the 
emission designator. If a prior coordination notice (PCN) under Sec.  
101.103(d) of this chapter is prepared, AWS entities can satisfy the 
site-data filing requirement by submitting a copy of their PCN to the 
clearinghouse. AWS entities that file either a notice or a PCN have a 
continuing duty to maintain the accuracy of the site-specific data on 
file with the clearinghouse. Utilizing the site-specific data, the 
clearinghouse will determine if any reimbursement obligation exists and 
notify the AWS entity in writing of its repayment obligation, if any. 
When the AWS entity receives a written copy of such obligation, it must 
pay directly to the relocator the amount owed within 30 calendar days.

[78 FR 8271, Jan. 5, 2013]



Sec.  27.1172  Dispute Resolution Under the Cost-Sharing Plan.

    (a) Disputes arising out of the cost-sharing plan, such as disputes 
over the amount of reimbursement required, must be brought, in the first 
instance, to the clearinghouse for resolution. To the extent that 
disputes cannot be resolved by the clearinghouse, parties are encouraged 
to use expedited Alternative Dispute Resolution (ADR) procedures, such 
as binding arbitration, mediation, or other ADR techniques.
    (b) Evidentiary requirement. Parties of interest contesting the 
clearinghouse's determination of specific cost-sharing obligations must 
provide evidentiary support to demonstrate that their calculation is 
reasonable and made in good faith. Specifically, these parties are 
expected to exercise due diligence to obtain the information necessary 
to prepare an independent estimate of the relocation costs in question 
and to file the independent estimate and supporting documentation with 
the clearinghouse.



Sec.  27.1174  Termination of cost-sharing obligations.

    The cost-sharing plan will sunset for all AWS and MSS entities on 
the same date on which the relocation obligation for the subject AWS 
band (i.e., 2110-2150 MHz, 2160-2175 MHz, 2175-2180 MHz, 2180-2200 MHz) 
in which the relocated FMS link was located terminates. AWS or MSS 
entrants that trigger a cost-sharing obligation prior to the sunset date 
must satisfy their payment obligation in full.

Cost-Sharing Policies Governing Broadband Radio Service Relocation From 
                        the 2150-2160/62 MHz Band

    Source: Sections 27.1176 through 27.1190 appear at 71 FR 29835, May 
24, 2006, unless otherwise noted.



Sec.  27.1176  Cost-sharing requirements for AWS in the 2150-2160/62 MHz
band.

    (a) Frequencies in the 2150-2160/62 MHz band have been reallocated 
from the Broadband Radio Service (BRS) to AWS. All AWS entities who 
benefit from another AWS entity's clearance of BRS incumbents from this 
spectrum, including BRS incumbents occupying the 2150-2162 MHz band on a 
primary basis, must contribute to such relocation costs. Only AWS 
entrants that relocate BRS incumbents are entitled to such 
reimbursement.
    (b) AWS entities may satisfy their reimbursement requirement by 
entering into private cost-sharing agreements or agreeing to terms other 
than those specified in Sec.  27.1180. However, AWS entities are 
required to reimburse other AWS entities that incur relocation costs and 
are not parties to the alternative agreement. In addition, parties to a 
private cost-sharing agreement may seek reimbursement through the 
clearinghouse (as discussed in Sec.  27.1178) from AWS entities that are 
not parties to the agreement. The cost-sharing plan is in effect during 
all phases of BRS relocation until the end of the period specified in 
Sec.  27.1190. If an AWS licensee enters into a spectrum leasing 
arrangement and the spectrum lessee triggers a cost-sharing obligation, 
the

[[Page 386]]

licensee is the AWS entity responsible for satisfying cost-sharing 
obligations under these rules.



Sec.  27.1178  Administration of the Cost-Sharing Plan.

    The Wireless Telecommunications Bureau, under delegated authority, 
will select one or more entities to operate as a neutral, not-for-profit 
clearinghouse(s). This clearinghouse(s) will administer the cost-sharing 
plan by, inter alia, determining the cost-sharing obligations of AWS 
entities for the relocation of BRS incumbents from the 2150-2162 MHz 
band. The clearinghouse filing requirements (see Sec. Sec.  27.1182(a), 
27.1186) will not take effect until an administrator is selected.



Sec.  27.1180  The cost-sharing formula.

    (a) An AWS licensee that relocates a BRS system with which it 
interferes is entitled to pro rata reimbursement based on the cost-
sharing formula specified in Sec.  27.1164, except that the depreciation 
factor shall be [180-Tm]/180, and the variable C shall be 
applied as set forth in paragraph (b) of this section.
    (b) C is the actual cost of relocating the system, and includes, but 
is not limited to, such items as: Radio terminal equipment (TX and/or 
RX--antenna, necessary feed lines, MUX/Modems); towers and/or 
modifications; back-up power equipment; monitoring or control equipment; 
engineering costs (design/path survey); installation; systems testing; 
FCC filing costs; site acquisition and civil works; zoning costs; 
training; disposal of old equipment; test equipment (vendor required); 
spare equipment; project management; site lease renegotiation; required 
antenna upgrades for interference control; power plant upgrade (if 
required); electrical grounding systems; Heating Ventilation and Air 
Conditioning (HVAC) (if required); alternate transport equipment; leased 
facilities; and end user units served by the base station that is being 
relocated. In addition to actual costs, C may include the cost of an 
independent third party appraisal conducted pursuant to Sec.  
27.1182(a)(3) and incumbent transaction expenses that are directly 
attributable to the relocation, subject to a cap of two percent of the 
``hard'' costs involved. Hard costs are defined as the actual costs 
associated with providing a replacement system, such as equipment and 
engineering expenses. There is no cap on the actual costs of relocation.
    (c) An AWS system shall be considered an interfering system for 
purposes of this rule if the AWS system is in all or part of the BRS 
frequency band and operates within line of sight to BRS operations under 
the applicable test specified in Sec.  27.1184. An AWS relocator that 
relocates a BRS system with which it does not interfere is entitled to 
full reimbursement, as specified in Sec.  27.1182(c).



Sec.  27.1182  Reimbursement under the Cost-Sharing Plan.

    (a) Registration of reimbursement rights. (1) To obtain 
reimbursement, an AWS relocator must submit documentation of the 
relocation agreement to the clearinghouse within 30 calendar days of the 
date a relocation agreement is signed with an incumbent. In the case of 
involuntary relocation, an AWS relocator must submit documentation of 
the relocated system within 30 calendar days after the end of the one-
year trial period.
    (2) Registration of any BRS system shall include:
    (i) A description of the system's frequency use;
    (ii) If the system exclusively provides one-way transmissions to 
subscribers, the Geographic Service Area of the system; and
    (iii) If the system does not exclusively provide one-way 
transmission to subscribers, the system hub antenna's geographic 
location and the above ground level height of the system's receiving 
antenna centerline.
    (3) The AWS relocator must also include with its system registration 
an independent third party appraisal of the compensable relocation 
costs. The appraisal should be based on the actual cost of replacing the 
incumbent's system with comparable facilities and should exclude the 
cost of any equipment upgrades that are not necessary to the provision 
of comparable facilities. An AWS relocator may submit

[[Page 387]]

registration without a third party appraisal if it consents to binding 
resolution by the clearinghouse of any good faith cost disputes 
regarding the reimbursement claim, under the following standard: The 
relocator shall bear the burden of proof, and be required to demonstrate 
by clear and convincing evidence that its request does not exceed the 
actual cost of relocating the relevant BRS system or systems to 
comparable facilities. Failure to satisfy this burden of proof will 
result in loss of rights to subsequent reimbursement of the disputed 
costs from any AWS licensee.
    (b) Documentation of expenses. Once relocation occurs, the AWS 
relocator must submit documentation itemizing the amount spent for items 
specifically listed in Sec.  27.1180(b), as well as any reimbursable 
items not specifically listed in Sec.  27.1180(b) that are directly 
attributable to actual relocation costs. Specifically, the AWS relocator 
must submit, in the first instance, only the uniform cost data requested 
by the clearinghouse along with copies, without redaction, of the 
relocation agreement, if any, and the third party appraisal described in 
(a)(3), of this section, if prepared. The AWS relocator must identify 
the particular system associated with appropriate expenses (i.e., costs 
may not be averaged over numerous systems). If an AWS relocator pays a 
BRS incumbent a monetary sum to relocate its own facilities in whole or 
in part, the AWS relocator must itemize the actual costs to the extent 
determinable, and otherwise must estimate the actual costs associated 
with relocating the incumbent and itemize these costs. If the sum paid 
to the incumbent cannot be accounted for, the remaining amount is not 
eligible for reimbursement. All AWS relocators seeking reimbursement 
through the clearinghouse have an ongoing duty to maintain all relevant 
records of BRS relocation-related expenses until the sunset of cost-
sharing obligations, and to provide, upon request, such documentation, 
including a copy of the independent appraisal if one was conducted, to 
the clearinghouse, the Commission, or AWS entrants that trigger a cost-
sharing obligation.
    (c) Full reimbursement. An AWS relocator who relocates a BRS system 
that is either:
    (1) Wholly outside its frequency band; or
    (2) Not within line of sight of the relocator's transmitting base 
station may seek full reimbursement through the clearinghouse of 
compensable costs. Such reimbursement will not be subject to 
depreciation under the cost-sharing formula.
    (d) Good Faith Requirement. New entrants and incumbent licensees are 
expected to act in good faith in satisfying the cost-sharing obligations 
under Sec. Sec.  27.1176 through 27.1190. The requirement to act in good 
faith extends to, but is not limited to, the preparation and submission 
of the documentation required in paragraph (b) of this section.



Sec.  27.1184  Triggering a reimbursement obligation.

    (a) The clearinghouse will apply the following test to determine 
when an AWS entity has triggered a cost-sharing obligation and therefore 
must pay an AWS relocator of a BRS system in accordance with the formula 
detailed in Sec.  27.1180:
    (1) All or part of the relocated BRS system was initially co-channel 
with the licensed AWS band(s) of the AWS entity;
    (2) An AWS relocator has paid the relocation costs of the BRS 
incumbent; and
    (3) The other AWS entity has turned on or is preparing to turn on a 
fixed base station at commercial power and the incumbent BRS system 
would have been within the line of sight of the AWS entity's fixed base 
station, defined as follows.
    (i) For a BRS system using the 2150-2160/62 MHz band exclusively to 
provide one-way transmissions to subscribers, the clearinghouse will 
determine whether there is an unobstructed signal path (line of sight) 
to the incumbent licensee's geographic service area (GSA), based on the 
following criteria: use of 9.1 meters (30 feet) for the receiving 
antenna height, use of the actual transmitting antenna height and 
terrain elevation, and assumption of 4/3 Earth radius propagation 
conditions.

[[Page 388]]

Terrain elevation data must be obtained from the U.S. Geological Survey 
(USGS) 3-second database. All coordinates used in carrying out the 
required analysis shall be based upon use of NAD-83.
    (ii) For all other BRS systems using the 2150-2160/62 MHz band, the 
clearinghouse will determine whether there is an unobstructed signal 
path (line of sight) to the incumbent licensee's receive station hub 
using the method prescribed in ``Methods for Predicting Interference 
from Response Station Transmitters and to Response Station Hubs and for 
Supplying Data on Response Station Systems. MM Docket 97-217,'' in 
Amendment of 47 CFR parts 1, 21 and 74 to Enable Multipoint Distribution 
Service and Instructional Television Fixed Service Licensees to Engage 
in Fixed Two-Way Transmissions, MM Docket No. 97-217, Report and Order 
on Further Reconsideration and Further Notice of Proposed Rulemaking, 15 
FCC Rcd 14566 at 14610, Appendix D.
    (b) If the application of the trigger test described in paragraphs 
(a)(3)(i) and (ii) of this section, indicates that a reimbursement 
obligation exists, the clearinghouse will calculate the reimbursement 
amount in accordance with the cost-sharing formula and notify the 
subsequent AWS entity of the total amount of its reimbursement 
obligation.
    (c) Once a reimbursement obligation is triggered, the AWS entity may 
not avoid paying its cost-sharing obligation by deconstructing or 
modifying its facilities.



Sec.  27.1186  Payment issues.

    Payment of cost-sharing obligations for the relocation of BRS 
systems in the 2150-60/62 MHz band is subject to the rules set forth in 
Sec.  27.1170. If an AWS licensee is initiating operations for a newly 
constructed site or modified existing site in licensed bands overlapping 
the 2150-2160/62 MHz band, the AWS licensee must file with the 
clearinghouse, in addition to the site-specific data required by Sec.  
27.1170, the above ground level height of the transmitting antenna 
centerline. AWS entities have a continuing duty to maintain the accuracy 
of the site-specific data on file with the clearinghouse.

Sec.  27.1188  Dispute resolution under the Cost-Sharing Plan.

    (a) Disputes arising out of the cost-sharing plan, such as disputes 
over the amount of reimbursement required, must be brought, in the first 
instance, to the clearinghouse for resolution. To the extent that 
disputes cannot be resolved by the clearinghouse, parties are encouraged 
to use expedited Alternative Dispute Resolution (ADR) procedures, such 
as binding arbitration, mediation, or other ADR techniques.
    (b) Evidentiary requirement. Parties of interest contesting the 
clearinghouse's determination of specific cost-sharing obligations must 
provide evidentiary support to demonstrate that their calculation is 
reasonable and made in good faith. Specifically, these parties are 
expected to exercise due diligence to obtain the information necessary 
to prepare an independent estimate of the relocation costs in question 
and to file the independent estimate and supporting documentation with 
the clearinghouse.



Sec.  27.1190  Termination of cost-sharing obligations.

    The plan for cost-sharing in connection with BRS relocation will 
sunset for all AWS entities fifteen years after the relocation sunset 
period for BRS relocation commences, i.e., fifteen years after the first 
AWS licenses are issued in any part of the 2150-2162 MHz band. AWS 
entrants that trigger a cost-sharing obligation prior to the sunset date 
must satisfy their payment obligation in full.

served by the cable operator's cable system and the cable operator will 
be using the BRS station as a multichannel video programming distributor 
(as defined in Sec.  76.64(d) of this chapter). No cable operator may 
acquire such authorization either directly, or indirectly through an 
affiliate owned, operated, or controlled by or under common control with 
a cable operator if the cable operator will use the BRS station as a 
multichannel video programming distributor.
    (b) No licensee of a station in this service may lease transmission 
time or capacity to a cable operator either directly, or indirectly 
through an affiliate owned, operated, controlled by, or under common 
control with a cable operator, if a portion of the BRS station's 
protected services area is within the portion of the franchise area 
actually served by the cable operator's cable system the cable operator 
will use the BRS station as a multichannel video programming 
distributor.
    (c) Applications for new stations, station modifications, 
assignments or transfers of control by cable operators of BRS stations 
shall include a showing that no portion of the GSA of the BRS station is 
within the portion of the franchise area actually served by the cable 
operator's cable system, or of any entity indirectly affiliated, owned, 
operated, controlled by, or under common control with the cable 
operator. Alternatively, the cable operator may certify that it will not 
use the BRS station to distribute multichannel video programming.
    (d) In applying the provisions of this section, ownership and other 
interests in BRS licensees or cable television systems will be 
attributed to their holders and deemed cognizable pursuant to the 
following criteria:
    (1) Except as otherwise provided herein, partnership and direct 
ownership interests and any voting stock interest amounting to 5% or 
more of the outstanding voting stock of a corporate BRS licensee or 
cable television system will be cognizable;
    (2) Investment companies, as defined in 15 U.S.C. 80a-3, insurance 
companies and banks holding stock through their trust departments in 
trust accounts will be considered to have a cognizable interest only if 
they hold 20% or more of the outstanding voting stock of a corporate BRS 
licensee or cable television system, or if any of the officers or 
directors of the BRS licensee or cable television system are 
representatives of the investment company, insurance company or bank 
concerned. Holdings by a bank or insurance company will be aggregated if 
the bank or insurance company has any right to determine how the stock 
will be voted. Holdings by investment companies will be aggregated if 
under common management.
    (3) Attribution of ownership interests in a BRS licensee or cable 
television system that are held indirectly by any party through one or 
more intervening corporations will be determined by successive 
multiplication of the ownership percentages for each link in the 
vertical ownership chain and application of the relevant attribution 
benchmark to the resulting product, except that wherever the ownership 
percentage for any link in the chain exceeds 50%, it shall not be 
included for purposes of this multiplication. For purposes of paragraph 
(d)(9) of this section, attribution of ownership interests in a BRS 
licensee or cable television system that are held indirectly by any 
party through one or more intervening organizations will be determined 
by successive multiplication of the ownership percentages for each link 
in the vertical ownership chain and application of the relevant 
attribution benchmark to the resulting product, and the ownership 
percentage for any link in

[[Page 390]]

the chain that exceeds 50% shall be included for purposes of this 
multiplication. For example, except for purposes of paragraph (d)(9) of 
this section, if A owns 10% of company X, which owns 60% of company Y, 
which owns 25% of ``Licensee,'' then X's interest in ``Licensee'' would 
be 25% (the same as Y's interest because X's interest in Y exceeds 50%), 
and A's interest in ``Licensee'' would be 2.5% (0.1 x 0.25). Under the 
5% attribution benchmark, X's interest in ``Licensee'' would be 
cognizable, while A's interest would not be cognizable. For purposes of 
paragraph (d)(9) of this section, X's interest in ``Licensee'' would be 
15% (0.6 x 0.25) and A's interest in ``Licensee'' would be 1.5% (0.1 x 
0.6 x 0.25). Neither interest would be attributed under paragraph (d)(9) 
of this section.
    (4) Voting stock interests held in trust shall be attributed to any 
person who holds or shares the power to vote such stock, to any person 
who has the sole power to sell such stock, and to any person who has the 
right to revoke the trust at will or to replace the trustee at will. If 
the trustee has a familial, personal or extra-trust business 
relationship to the grantor or the beneficiary, the grantor or 
beneficiary, as appropriate, will be attributed with the stock interests 
held in trust. An otherwise qualified trust will be ineffective to 
insulate the grantor or beneficiary from attribution with the trust's 
assets unless all voting stock interests held by the grantor or 
beneficiary in the relevant BRS licensee or cable television system are 
subject to said trust.
    (5) Subject to paragraph (d)(9) of this section, holders of non-
voting stock shall not be attributed an interest in the issuing entity. 
Subject to paragraph (d)(9) of this section, holders of debt and 
instruments such as warrants, convertible debentures, options or other 
non-voting interests with rights of conversion to voting interests shall 
not be attributed unless and until conversion is effected.
    (6)(i) A limited partnership interest shall be attributed to a 
limited partner unless that partner is not materially involved, directly 
or indirectly, in the management or operation of the BRS or cable 
television activities of the partnership and the licensee or system so 
certifies. An interest in a Limited Liability Company (``LLC'') or 
Registered Limited Liability Partnership (``RLLP'') shall be attributed 
to the interest holder unless that interest holder is not materially 
involved, directly or indirectly, in the management or operation of the 
BRS or cable television activities of the partnership and the licensee 
or system so certifies.
    (ii) For a licensee or system that is a limited partnership to make 
the certification set forth in paragraph (d)(6)(i) of this section, it 
must verify that the partnership agreement or certificate of limited 
partnership, with respect to the particular limited partner exempt from 
attribution, establishes that the exempt limited partner has no material 
involvement, directly or indirectly, in the management or operation of 
the BRS or cable television activities of the partnership. For a 
licensee or system that is an LLC or RLLP to make the certification set 
forth in paragraph (d)(6)(i) of this section, it must verify that the 
organizational document, with respect to the particular interest holder 
exempt from attribution, establishes that the exempt interest holder has 
no material involvement, directly or indirectly, in the management or 
operation of the BRS or cable television activities of the LLC or RLLP. 
Irrespective of the terms of the certificate of limited partnership or 
partnership agreement, or other organizational document in the case of 
an LLC or RLLP, however, no such certification shall be made if the 
individual or entity making the certification has actual knowledge of 
any material involvement of the limited partners, or other interest 
holders in the case of an LLC or RLLP, in the management or operation of 
the BRS or cable television businesses of the partnership or LLC or 
RLLP.
    (iii) In the case of an LLC or RLLP, the licensee or system seeking 
installation shall certify, in addition, that the relevant state statute 
authorizing LLCs permits an LLC member to insulate itself as required by 
our criteria.
    (7) Officers and directors of a BRS licensee or cable television 
system are considered to have a cognizable interest in the entity with 
which they are so associated. If any such entity engages

[[Page 391]]

in businesses in addition to its primary business of BRS or cable 
television service, it may request the Commission to waive attribution 
for any officer or director whose duties and responsibilities are wholly 
unrelated to its primary business. The officers and directors of a 
parent company of a BRS licensee or cable television system, with an 
attributable interest in any such subsidiary entity, shall be deemed to 
have a cognizable interest in the subsidiary unless the duties and 
responsibilities of the officer or director involved are wholly 
unrelated to the BRS licensee or cable television system subsidiary, and 
a statement properly documenting this fact is submitted to the 
Commission. The officers and directors of a sister corporation of a BRS 
licensee or cable television system shall not be attributed with 
ownership of these entities by virtue of such status.
    (8) Discrete ownership interests will be aggregated in determining 
whether or not an interest is cognizable under this section. An 
individual or entity will be deemed to have a cognizable investment if:
    (i) The sum of the interests held by or through ``passive 
investors'' is equal to or exceeds 20 percent; or
    (ii) The sum of the interests other than those held by or through 
``passive investors'' is equal to or exceeds 5 percent; or
    (iii) The sum of the interests computed under paragraph (d)(8)(i) of 
this section plus the sum of the interests computed under paragraph 
(d)(8)(ii) of this section equal to or exceeds 20 percent.
    (9) Notwithstanding paragraphs (d)(5) and (d)(6) of this section, 
the holder of an equity or debt interest or interests in a BRS licensee 
or cable television system subject to the BRS/cable cross-ownership rule 
(``interest holder'') shall have that interest attributed if:
    (i) The equity (including all stockholdings, whether voting or 
nonvoting, common or preferred) and debt interest or interests, in the 
aggregate, exceed 33 percent of the total asset value (all equity plus 
all debt) of that BRS licensee or cable television system; and
    (ii) The interest holder also holds an interest in a BRS licensee or 
cable television system that is attributable under this section (other 
than this paragraph) and which operates in any portion of the franchise 
area served by that cable operator's cable system.
    (10) The term ``area served by a cable system'' means any area 
actually passed by the cable operator's cable system and which can be 
connected for a standard connection fee.
    (11) As used in this section ``cable operator'' shall have the same 
definition as in Sec.  76.5 of this chapter.
    (e) The Commission will entertain requests to waive the restrictions 
in paragraph (a) of this section where necessary to ensure that all 
significant portions of the franchise area are able to obtain 
multichannel video service.
    (f) The provisions of paragraphs (a) through (e) of this section 
will not apply to one BRS channel used to provide locally-produced 
programming to cable headends. Locally-produced programming is 
programming produced in or near the cable operator's franchise area and 
not broadcast on a television station available within that franchise 
area. A cable operator will be permitted one BRS channel for this 
purpose, and no more than one BRS channel may be used by a cable 
television company or its affiliate or lessor pursuant to this 
paragraph. The licensee for a cable operator providing local programming 
pursuant to a lease must include in a notice filed with the Wireless 
Telecommunications Bureau a cover letter explicitly identifying itself 
or its lessees as a local cable operator and stating that the lease was 
executed to facilitate the provision of local programming. The first 
application or the first lease notification in an area filed with the 
Commission will be entitled to the exemption. The limitations on one BRS 
channel per party and per area include any cable/BRS operations or 
cable/EBS operations. The cable operator must demonstrate in its BRS 
application that the proposed local programming will be provided within 
one year from the date its application is granted. Local programming 
service pursuant to a lease must be provided within one year of the date 
of the lease or one year of grant of the licensee's application for the 
leased channel, whichever is later. If a BRS license for

[[Page 392]]

these purposes is granted and the programming is subsequently 
discontinued, the license will be automatically forfeited the day after 
local programming service is discontinued.
    (g) Applications filed by cable television companies, or affiliates, 
for BRS channels prior to February 8, 1990, will not be subject to the 
prohibitions of this section. Applications filed on February 8, 1990, or 
thereafter will be returned. Lease arrangements between cable and BRS 
entities for which a lease or a firm agreement was signed prior to 
February 8, 1990, will also not be subject to the prohibitions of this 
section. Leases between cable television companies, or affiliates, and 
BRS station licensees, conditional licensees, or applicants executed on 
February 8, 1990, or thereafter, are invalid.
    (1) Applications filed by cable operators, or affiliates, for BRS 
channels prior to February 8, 1990, will not be subject to the 
prohibitions of this section. Except as provided in paragraph (g)(2)of 
this section, applications filed on February 8, 1990, or thereafter will 
be returned. Lease arrangements between cable and BRS entities for which 
a lease or a firm agreement was signed prior to February 8, 1990, will 
also not be subject to the prohibitions of this section. Except as 
provided in paragraph (g)(2) of this section, leases between cable 
operators, or affiliates, and BRS/EBS station licensees, conditional 
licensees, or applicants executed on or before February 8, 1990, or 
thereafter are invalid.
    (2) Applications filed by cable operators, or affiliates for BRS 
channels after February 8, 1990, and prior to October 5, 1992, will not 
be subject to the prohibition of this section, if, pursuant to the then 
existing overbuild or rural exceptions, the applications were allowed 
under the then existing cable/BRS cross-ownership prohibitions. Lease 
arrangements between cable operators and BRS entities for which a lease 
or firm agreement was signed after February 8, 1990, and prior to 
October 5, 1992, will not be subject to the prohibitions of this 
section, if, pursuant to the then existing rural and overbuild 
exceptions, the lease arrangements were allowed.
    (3) The limitations on cable television ownership in this section do 
not apply to any cable operator in any franchise area in which a cable 
operator is subject to effective competition as determined under section 
623(l) of the Communications Act.

Sec.  27.1203  [Reserved]



Sec.  27.1204  EBS Tribal priority filing window.

    (a) The Commission will specify by public notice a window filing 
period for applications for new EBS stations on rural Tribal Lands. EBS 
applications for new facilities will be accepted only during this 
window. Applications submitted prior to the window opening date 
identified in the public notice will be returned as premature. 
Applications submitted after the deadline will be dismissed with 
prejudice as untimely.
    (b) Applicants in the Tribal priority filing window must demonstrate 
that they are eligible to file in that window. To be considered eligible 
for the Tribal priority window, an applicant must be:
    (1) A federally recognized American Indian Tribe or Alaska Native 
Village; or an entity that is owned and controlled by a federally-
recognized Tribe or a consortium of federally-recognized Tribes;
    (2) Requesting a license on Tribal Land, which is defined to be any 
federally recognized Indian Tribe's reservation, pueblo or colony, 
including former reservations in Oklahoma, Alaska Native regions 
established pursuant to the Alaska Native Claims Settlement Act (85 
Stat. 688) and Indian Allotments, see Sec.  54.400(e) of this chapter, 
as well as Hawaiian Home Lands--areas held in trust for native Hawaiians 
by the State of Hawaii, pursuant to the Hawaiian Homes Commission Act, 
1920, July 9, 1921, 42 Stat 108, et seq., as amended; and any lands 
designated prior to July 10, 2019, as Tribal Lands pursuant to the 
designation process contained in Sec.  54.412 of this chapter;
    (3) Requesting a GSA in a rural area, which is defined to be lands 
that are not part of an urbanized area or urban

[[Page 393]]

cluster area with a population equal to or greater than 50,000; and
    (4) Have a local presence on the Tribal Land for which they are 
applying.
    (c) Following the close of the Tribal priority window, the 
Commission will issue a public notice of acceptance for filing of 
applications submitted pursuant to paragraph (b) of this section that 
meet technical and legal requirements and that are not in conflict with 
any other application filed during the window. Petitions to deny such 
applications may be filed within 30 days of such public notice. A copy 
of any petition to deny must be served on the applicant.
    (d) If applications are filed in the Tribal priority window that are 
mutually exclusive, the Commission will use competitive bidding to 
resolve the mutual exclusivity. Two or more pending applications are 
mutually exclusive if the grant of one application would effectively 
preclude the grant of one or more of the others under Commission rules 
in this chapter.
    (e) For non-mutually exclusive applications, the applications will 
be processed in accordance with procedures to be specified by the 
Wireless Telecommunications Bureau.

Sec.  27.1206  Geographic service area.

    (a) BRS:
    (1) For BRS incumbent licenses granted before September 15, 1995, 
the geographic service area (GSA) is the area that is bounded by a 
circle having a 35 mile radius and centered at the station's reference 
coordinates, which was the previous PSA entitled to incumbent licensees 
prior to January 10, 2005, and is bounded by the chord(s) drawn between 
intersection points of the licensee's previous 35 mile PSA and those of 
respective adjacent market, co-channel licensees;
    (2) For BRS BTA authorization holders, the GSA for a channel is the 
BTA, subject to the exclusion of overlapping, co-channel incumbent GSAs 
created on January 10, 2005.
    (3) If an incumbent BRS license is cancelled or is forfeited, the 
GSA area of the incumbent station shall dissolve and the right to 
operate in that area automatically reverts to the GSA licensee that held 
the corresponding BTA.
    (b) EBS:
    (1) Existing EBS licensees. (i) The GSA of EBS licenses on the E and 
F channel groups is defined in Sec.  27.1216. EBS licensees on the E and 
F channel groups are prohibited from expanding their GSAs.
    (ii) For incumbent EBS licenses not in the E and F channel groups in 
effect as of October 25, 2019, the geographic service area (GSA) is the 
area that is bounded by a circle having a 35 mile radius and centered at 
the station's reference coordinates, which was the previous PSA entitled 
to incumbent licensees prior to January 10, 2005, and is bounded by the 
chord(s) drawn between intersection points of the licensee's previous 35 
mile PSA and those of respective adjacent market, co-channel licensees.
    (2) New initial EBS licenses. (i) For EBS licenses issued in the 
Tribal Priority Window, the GSA consists of the rural Tribal Land (as 
defined in Sec.  27.1204(b)(3)) specified in the application.
    (ii) For all other new initial licenses issued after April 27, 2020, 
the GSA is the county for which the license is issued, subject to the 
exclusion of overlapping, co-channel incumbent GSAs.

[[Page 394]]



Sec.  27.1207  Service areas and authorizations.

    (a) Initial authorizations for BRS granted after January 1, 2008, 
shall be blanket licenses for all BRS frequencies identified in Sec.  
27.5(i)(2). Except for incumbent BRS licenses, BRS service areas are the 
1992 version of Basic Trading Areas (BTAs) defined by Rand McNally, or 
additional service areas similar to BTAs adopted by the Commission. The 
market area for each license will be listed on the license 
authorization. The following are additional BRS service areas in places 
where Rand McNally has not defined BTAs: American Samoa; Guam; Gulf of 
Mexico Zone A; Gulf of Mexico Zone B; Gulf of Mexico Zone C; Northern 
Mariana Islands; Mayaguez/Aguadilla-Ponce, Puerto Rico; San Juan, Puerto 
Rico; and the United States Virgin Islands. The boundaries of Gulf of 
Mexico Zone A are from an area twelve nautical miles from the shoreline 
at mean high tide on the north and east, to the limit of the Outer 
Continental Shelf to the south, and to longitude 91[deg]00[min] to the 
west. The boundaries of Gulf of Mexico Zone B are from an area twelve 
nautical miles from the shoreline at mean high tide on the north, to the 
limit of the Outer Continental Shelf to the south, to longitude 
91[deg]00[min] to the east, and to longitude 94[deg]00[min] to the west. 
The boundaries of Gulf of Mexico Zone C are from an area twelve nautical 
miles from the shoreline at mean high tide on the north and west, to 
longitude 94[deg]00[min] to the east, and to a line 281 kilometers from 
the reference point at Linares, N.L., Mexico on the southwest. The

Penuelas, Ponce, Quebradillas, Rinc[oacute]n, Sabana Grande, Salinas, 
San German, Santa Isabel, Villalba and Yauco. The San Juan service area 
consists of all other municipios in Puerto Rico.
    (b) For EBS initial licenses issued after October 25, 2019, except 
for licenses issued in the Tribal Priority Window, the GSA is the county 
for which the license is issued, subject to the exclusion of 
overlapping, co-channel incumbent GSAs. For purposes of this subpart, 
counties are defined using the United States Census Bureau's data 
reflecting county legal boundaries and names valid through January 1, 
2017. Except for licenses issued in the Tribal Priority Window, there 
shall be three initial authorizations issued in each county: One 
authorization for channels A1, A2, A3, B1, B2, B3, C1, C2, and C3; the 
second authorization for channels D1, D2, D3, JA1, JA2, JA3, JB1, JB2,

Sec.  27.1208  Geographic area licensing.

    (a) All BRS and EBS licenses are geographic area licenses. Blanket 
licenses cover all mobile and response stations. Pursuant to that 
geographic area license, incumbent licensees may modify their systems 
provided the modified system complies with the applicable rules in this 
chapter. The blanket license covers all fixed stations anywhere within 
the authorized service area, except a station must be individually 
licensed if:
    (1) International agreements require coordination;
    (2) Submission of an Environmental Assessment is required under 
Sec.  1.1307 of this chapter; and
    (3) The station would affect the radio quiet zones under Sec.  1.924 
of this chapter.
    (b) Any antenna structure that requires notification to the Federal 
Aviation Administration (FAA) must be registered with the Commission 
prior to construction under Sec.  17.4 of this chapter.

Sec.  27.1209  Reversion and overlay rights.

    (a) The frequencies associated with BRS incumbent authorizations 
that have cancelled automatically or otherwise recovered by the 
Commission automatically revert to the applicable BRS BTA licensee.
    (b) The frequencies associated with EBS incumbent authorizations 
with a

[[Page 395]]

geographic service area that have cancelled automatically or otherwise 
recovered by the Commission automatically revert to a co-channel EBS 
county-based licensee, except that if the area in question is Tribal 
Land as defined in Sec.  27.1204(b)(3) and is contiguous to the GSA of a 
co-channel authorization issued in the Tribal Priority Window, the area 
consisting of Tribal Land reverts to the co-channel license issued in 
the Tribal Priority Window.
    (c) The frequencies associated with EBS authorizations issued in the 
Tribal Priority Window with a geographic service area that have 
cancelled automatically or otherwise recovered by the Commission 
automatically revert to a co-channel EBS county-based authorization.

[84 FR 57366, Oct. 25, 2019]



Sec.  27.1210  Remote control operation.

    Licensed BRS/EBS stations may be operated by remote control without 
further authority.



Sec.  27.1211  Unattended operation.

    Unattended operation of licensed BRS/EBS stations is permitted 
without further authority. An unattended relay station may be employed 
to receive and retransmit signals of another station provided that the 
transmitter is equipped with circuits which permit it to radiate only 
when the signal intended to be retransmitted is present at the receiver 
input terminals.



Sec.  27.1212  License term.

    (a) BRS/EBS licenses shall be issued for a period of 10 years 
beginning with the date of grant.
    (b) An initial BTA authorization shall be issued for a period of ten 
years from the date the Commission declared bidding closed in the MDS 
auction.



Sec.  27.1213  Designated entity provisions for BRS in Commission 
auctions commencing prior to January 1, 2004.

    (a) Eligibility for small business provisions. For purposes of 
Commission auctions commencing prior to January 1, 2004 for BRS 
licenses, a small business is an entity that together with its 
affiliates has average annual gross revenues that are not more than $40 
million for the preceding three calendar years.
    (b) Designated entities. As specified in this section, designated 
entities that are winning bidders in Commission auctions commencing 
prior to January 1, 2004 for BTA service areas are eligible for special 
incentives in the auction process. See 47 CFR 1.2110.
    (c) Installment payments. Small businesses and small business 
consortia may elect to pay the full amount of their winning bids in 
Commission auctions commencing prior to January 1, 2004 for BTA service 
areas in installments over a ten (10) year period running from the date 
that their BTA authorizations are issued.
    (1) Upon issuance of a BTA authorization to a winning bidder in a 
Commission auction commencing prior to January 1, 2004 that is eligible 
for installment payments, the Commission will notify such eligible BTA 
authorization holder of the terms of its installment payment plan. For 
BRS, such installment payment plans will:
    (i) Impose interest based on the rate of ten (10) year U.S. Treasury 
obligations at the time of issuance of the BTA authorization, plus two 
and one half (2.5) percent;
    (ii) Allow installment payments for a ten (10) year period running 
from the date that the BTA authorization is issued;
    (iii) Begin with interest-only payments for the first two (2) years; 
and
    (iv) Amortize principal and interest over the remaining years of the 
ten (10) year period running from the date that the BTA authorization is 
issued.
    (2) Conditions and obligations. See Sec.  1.2110(g)(4) of this 
chapter.
    (3) Unjust enrichment. If an eligible BTA authorization holder that 
utilizes installment financing under this subsection seeks to partition, 
pursuant to applicable rules, a portion of its BTA containing one-third 
or more of the population of the area within its control in the licensed 
BTA to an entity not meeting the eligibility standards for installment 
payments, the holder must make full payment of the remaining unpaid 
principal and any unpaid interest accrued through the date of partition 
as a condition of approval.

[[Page 396]]

    (d) Reduced upfront payments. For purposes of Commission auctions 
commencing prior to January 1, 2004 for BRS licenses, a prospective 
bidder that qualifies as a small business, or as a small business 
consortia, is eligible for a twenty-five (25) percent reduction in the 
amount of the upfront payment otherwise required. To be eligible to bid 
on a particular BTA, a small business will be required to submit an 
upfront payment equal to seventy-five (75) percent of the upfront 
payment amount specified for that BTA in the public notice listing the 
upfront payment amounts corresponding to each BTA service area being 
auctioned.
    (e) Bidding credits. For purposes of Commission auctions commencing 
prior to January 1, 2004 for BRS licenses, a winning bidder that 
qualifies as a small business, or as a small business consortia, may use 
a bidding credit of fifteen (15) percent to lower the cost of its 
winning bid on any of the BTA authorizations awarded in the Commission 
BRS auctions commencing prior to January 1, 2004.
    (f) Short-form application certification; Long-form application or 
statement of intention disclosure. A BRS applicant in a Commission 
auction commencing prior to January 1, 2004 claiming designated entity 
status shall certify on its short-form application that it is eligible 
for the incentives claimed. A designated entity that is a winning bidder 
for a BTA service area(s) shall, in addition to information otherwise 
required, file an exhibit to either its initial long-form application 
for a BRS station license, or to its statement of intention with regard 
to the BTA, which discloses the gross revenues for each of the past 
three years of the winning bidder and its affiliates. This exhibit shall 
describe how the winning bidder claiming status as a designated entity 
satisfies the designated entity eligibility requirements, and must list 
and summarize all agreements that affect designated entity status, such 
as partnership agreements, shareholder agreements, management agreements 
and other agreements, including oral agreements, which establish that 
the designated entity will have both de facto and de jure control of the 
entity. See 47 CFR 1.2110(i).
    (g) Records maintenance. All holders of BTA authorizations acquired 
in a Commission auction commencing prior to January 1, 2004 that claim 
designated entity status shall maintain, at their principal place of 
business or with their designated agent, an updated documentary file of 
ownership and revenue information necessary to establish their status. 
Holders of BTA authorizations or their successors in interest shall 
maintain such files for a ten (10) year period running from the date 
that their BTA authorizations are issued. The files must be made 
available to the Commission upon request.

Sec.  27.1216  Grandfathered E and F group EBS licenses.

    (a) Except as noted in paragraph (b) of this section, grandfathered 
EBS licensees authorized to operate E and F group co-channel licenses 
are granted a geographic service area (GSA) on July 19, 2006. The GSA is 
the area bounded by a circle having a 35 mile radius and centered at the 
station's reference coordinates, and is bounded by the chord(s) drawn 
between intersection points of that circle and those of respective 
adjacent market, co-channel licensees.
    (b) If there is more than 50 percent overlap between the calculated 
GSA of a grandfathered EBS license and the protected service area of a 
co-channel BRS license, the licensees shall not be immediately granted a 
geographic service area. Instead, the grandfathered EBS license and the 
co-channel BRS licensee must negotiate in good faith to reach a solution 
that accommodates the communication needs of both licensees. If the co-
channel licensees reach a mutually agreeable solution on or before 
October 17, 2006, then the GSA of each co-channel license shall be as 
determined pursuant to the agreement of the parties. If a mutually 
agreeable solution between co-channel licensees is not reached on or 
before October 17, 2006, then each co-channel licensee shall receive a 
GSA determined pursuant to paragraph (a) of this section and Sec.  
27.1206(a).

                           Technical Standards



Sec.  27.1220  Transmission standards.

    The width of a channel in the LBS and UBS is 5.5 MHz, with the 
exception of BRS channels 1 and 2 which are 6.0 MHz. The width of all 
channels in the MBS is 6 MHz. However, the licensee may subchannelize 
its authorized bandwidth, provided that digital modulation is employed 
and the aggregate power does not exceed the authorized power for the 
channel. The licensee may also, jointly with other licensees, transmit 
utilizing bandwidth in excess of its authorized bandwidth, provided that 
digital modulation is employed, all power spectral density requirements 
set forth in this part are met and the out-of-band emissions 
restrictions set forth in Sec.  27.53 are met at the edges of the 
channels employed.



Sec.  27.1221  Interference protection.

    (a) Interference protection will be afforded to BRS and EBS on a 
station-by-station basis based on the heights of the stations in the LBS 
and UBS and also on height benchmarking, although the heights of 
antennas utilized are not restricted.
    (b) Height benchmarking. Height benchmarking is defined for pairs of 
base stations, one in each of two proximate geographic service areas 
(GSAs). The height benchmark, which is defined in meters 
(hbm) for a particular base station relative to a base 
station in another GSA, is equal to the distance, in kilometers, from 
the base station along a radial to the nearest point on the GSA boundary 
of the other base station squared (Dkm\2\) and then divided 
by 17. That is, hb (m) = Dkm\2\/17. A base station 
antenna will be considered to be within its applicable height benchmark 
relative to another base station if the height in meters of its 
centerline of radiation above average elevation (HAAE) calculated along 
the straight line between the two base stations in accordance with Sec.  
24.53(b) and (c) of this chapter does not exceed the height benchmark 
(hbm). A base station antenna will be considered to exceed 
its applicable height benchmark relative to another base station if the 
HAAE of its centerline of radiation calculated along the straight line 
between the two base stations in accordance with Sec.  24.53(b) and (c) 
of this chapter exceeds the height benchmark (hbm).
    (c) Protection for receiving antennas not exceeding the height 
benchmark. Absent agreement between the two licensees to the contrary, 
if a transmitting antenna of one BRS/EBS licensee's base station exceeds 
its applicable height benchmark and such licensee is notified by another 
BRS/EBS licensee that it is generating an undesired signal level in 
excess of -107 dBm/5.5 megahertz at the receiver of a co-channel base 
station that is within its applicable height benchmark, then the 
licensee of the base station that exceeds its applicable height 
benchmark shall either limit the undesired signal at the receiver of the 
protected base station to -107dBm/5.5 megahertz or less or reduce the 
height of its transmission antenna to no more than the height benchmark. 
If the interfering base station has been modified to increase the EIRP 
transmitted in the direction of the protected base station, it shall be 
deemed to have commenced operations

[[Page 399]]

on the date of such modification. Such corrective action shall be 
completed no later than:
    (i) 24 hours after receiving such notification, if the base station 
that exceeds its height benchmark commenced operations after the station 
that is within its applicable height benchmark; or
    (ii) 90 days after receiving such notification, if the base station 
that exceeds its height commenced operations prior to the station that 
is within its applicable height benchmark. For purposes of this section, 
if the interfering base station has been modified to increase the EIRP 
transmitted in the direction of the victim base station, it shall be 
deemed to have commenced operations on the date of such modification.
    (d) No Protection from a transmitting antenna not exceeding the 
height benchmark. The licensee of a base station transmitting antenna 
less than or equal to its applicable height benchmark shall not be 
required pursuant to paragraph (c) of this section to limit that 
antennas undesired signal level to -107dBm/5.5 megahertz or less at the 
receiver of any co-channel base station.
    (e) No protection for a receiving-antenna exceeding the height 
benchmark. The licensee of a base station receive antenna that exceeds 
its applicable height benchmark shall not be entitled pursuant to 
paragraph (c) of this section to insist that any co-channel base station 
limit its undesired signal level to -107dBm/5.5 megahertz or less at the 
receiver.
    (f) Information exchange. A BRS/EBS licensee shall provide the 
geographic coordinates, the height above ground level of the center of 
radiation for each transmit and receive antenna, and the date 
transmissions commenced for each of the base stations in its GSA within 
30 days of receipt of a request from a co-channel BRS/EBS licensee with 
an operational base station located in a proximate GSA. Information 
shared pursuant to this section shall not be disclosed to other parties 
except as required to ensure compliance with this section.

Sec.  27.1222  Operations in the 2568-2572 and 2614-2618 bands.

    All operations in the 2568-2572 and 2614-2618 MHz bands shall be 
secondary to adjacent-channel operations. Stations operating in the 
2568-2572 and 2614-2618 MHz must not cause interference to licensees in 
operation in the LBS, MBS, and UBS and must accept any interference from 
any station operating in the LBS, MBS, and UBS in compliance with the 
rules established in this subpart. Stations operating in the 2568-2572 
and 2614-2618 bands may cause interference to stations in operation in 
the LBS, MBS, and UBS if the affected licensees consent to such 
interference.

           Relocation Procedures for the 2150-2160/62 MHz Band

    Source: Sections 27.1250 through 27.1255 appear at 71 FR 29840, May 
24, 2006, unless otherwise noted.



Sec.  27.1250  Transition of the 2150-2160/62 MHz band from the Broadband
Radio Service to the Advanced Wireless Service.

    The 2150-2160/62 MHz band has been allocated for use by the Advanced 
Wireless Service (AWS). The rules in this section provide for a 
transition period during which AWS licensees may relocate existing 
Broadband Radio Service (BRS) licensees using these frequencies to their 
assigned frequencies in the 2496-2690 MHz band or other media.
    (a) AWS licensees and BRS licensees shall engage in mandatory 
negotiations for the purpose of agreeing to terms under which the BRS 
licensees would:
    (1) Relocate their operations to other frequency bands or other 
media; or alternatively
    (2) Accept a sharing arrangement with the AWS licensee that may 
result in an otherwise impermissible level of interference to the BRS 
operations.
    (b) If no agreement is reached during the mandatory negotiation 
period, an AWS licensee may initiate involuntary relocation procedures. 
Under involuntary relocation, the incumbent is required to relocate, 
provided that the AWS licensee meets the conditions of Sec.  27.1252.

[[Page 400]]

    (c) Relocation of BRS licensees by AWS licensees will be subject to 
a three-year mandatory negotiation period. BRS licensees may suspend the 
running of the three-year negotiation period for up to one year if the 
BRS licensee cannot be relocated to comparable facilities at the time 
the AWS licensee seeks entry into the band.



Sec.  27.1251  Mandatory negotiations.

    (a) Once mandatory negotiations have begun, a BRS licensee may not 
refuse to negotiate and all parties are required to negotiate in good 
faith. Good faith requires each party to provide information to the 
other that is reasonably necessary to facilitate the relocation process. 
The BRS licensee is required to cooperate with an AWS licensee's request 
to provide access to the facilities to be relocated, other than the BRS 
customer location, so that an independent third party can examine the 
BRS system and prepare an appraisal of the costs to relocate the 
incumbent. In evaluating claims that a party has not negotiated in good 
faith, the FCC will consider, inter alia, the following factors:
    (1) Whether the AWS licensee has made a bona fide offer to relocate 
the BRS licensee to comparable facilities in accordance with Sec.  
27.1252(b);
    (2) If the BRS licensee has demanded a premium, the type of premium 
requested (e.g., whether the premium is directly related to relocation, 
such as analog-to-digital conversions, versus other types of premiums), 
and whether the value of the premium as compared to the cost of 
providing comparable facilities is disproportionate (i.e., whether there 
is a lack of proportion or relation between the two);
    (3) What steps the parties have taken to determine the actual cost 
of relocation to comparable facilities;
    (4) Whether either party has withheld information requested by the 
other party that is necessary to estimate relocation costs or to 
facilitate the relocation process.
    (b) Any party alleging a violation of our good faith requirement 
must attach an independent estimate of the relocation costs in question 
to any documentation filed with the Commission in support of its claim. 
An independent cost estimate must include a specification for the 
comparable facility and a statement of the costs associated with 
providing that facility to the incumbent licensee.
    (c) Mandatory negotiations will commence for each BRS licensee when 
the AWS licensee informs the BRS licensee in writing of its desire to 
negotiate. Mandatory negotiations will be conducted with the goal of 
providing the BRS licensee with comparable facilities, defined as 
facilities possessing the following characteristics:
    (1) Throughput. Communications throughput is the amount of 
information transferred within a system in a given amount of time. 
System is defined as a base station and all end user units served by 
that base station. If analog facilities are being replaced with analog, 
comparable facilities may provide a comparable number of channels. If 
digital facilities are being replaced with digital, comparable 
facilities provide equivalent data loading bits per second (bps).
    (2) Reliability. System reliability is the degree to which 
information is transferred accurately within a system. Comparable 
facilities provide reliability equal to the overall reliability of the 
BRS system. For digital systems, reliability is measured by the percent 
of time the bit error rate (BER) exceeds a desired value, and for analog 
or digital video transmission, it is measured by whether the end-to-end 
transmission delay is within the required delay bound. If an analog 
system is replaced with a digital system, only the resulting frequency 
response, harmonic distortion, signal-to-noise ratio and its reliability 
will be considered in determining comparable reliability.
    (3) Operating Costs. Operating costs are the cost to operate and 
maintain the BRS system. AWS licensees would compensate BRS licensees 
for any increased recurring costs associated with the replacement 
facilities (e.g., additional rental payments, and increased utility 
fees) for five years after relocation. AWS licensees could satisfy this 
obligation by making a lump-sum payment based on present value using 
current interest rates. Additionally, the maintenance costs to the BRS 
licensee

[[Page 401]]

would be equivalent to the replaced system in order for the replacement 
system to be comparable.
    (d) AWS licensees are responsible for the relocation costs of end 
user units served by the BRS base station that is being relocated. If a 
lessee is operating under a BRS license, the BRS licensee may rely on 
the throughput, reliability, and operating costs of facilities in use by 
a lessee in negotiating comparable facilities and may include the lessee 
in negotiations.



Sec.  27.1252  Involuntary relocation procedures.

    (a) If no agreement is reached during the mandatory negotiation 
period, an AWS licensee may initiate involuntary relocation procedures 
under the Commission's rules. AWS licensees are obligated to pay to 
relocate BRS systems to which the AWS system poses an interference 
problem. Under involuntary relocation, the BRS licensee is required to 
relocate, provided that the AWS licensee:
    (1) Guarantees payment of relocation costs, including all 
engineering, equipment, site and FCC fees, as well as any legitimate and 
prudent transaction expenses incurred by the BRS licensee that are 
directly attributable to an involuntary relocation, subject to a cap of 
two percent of the ``hard'' costs involved. Hard costs are defined as 
the actual costs associated with providing a replacement system, such as 
equipment and engineering expenses. There is no cap on the actual costs 
of relocation. AWS licensees are not required to pay BRS licensees for 
internal resources devoted to the relocation process. AWS licensees are 
not required to pay for transaction costs incurred by BRS licensees 
during the mandatory period once the involuntary period is initiated, or 
for fees that cannot be legitimately tied to the provision of comparable 
facilities; and
    (2) Completes all activities necessary for implementing the 
replacement facilities, including engineering and cost analysis of the 
relocation procedure and, if radio facilities are used, identifying and 
obtaining, on the incumbents' behalf, new microwave frequencies and 
frequency coordination.
    (b) Comparable facilities. The replacement system provided to an 
incumbent during an involuntary relocation must be at least equivalent 
to the existing BRS system with respect to the following three factors:
    (1) Throughput. Communications throughput is the amount of 
information transferred within a system in a given amount of time. 
System is defined as a base station and all end user units served by 
that base station. If analog facilities are being replaced with analog, 
the AWS licensee is required to provide the BRS licensee with a 
comparable number of channels. If digital facilities are being replaced 
with digital, the AWS licensee must provide the BRS licensee with 
equivalent data loading bits per second (bps). AWS licensees must 
provide BRS licensees with enough throughput to satisfy the BRS 
licensee's system use at the time of relocation, not match the total 
capacity of the BRS system.
    (2) Reliability. System reliability is the degree to which 
information is transferred accurately within a system. AWS licensees 
must provide BRS licensees with reliability equal to the overall 
reliability of their system. For digital data systems, reliability is 
measured by the percent of time the bit error rate (BER) exceeds a 
desired value, and for analog or digital video transmissions, it is 
measured by whether the end-to-end transmission delay is within the 
required delay bound.
    (3) Operating costs. Operating costs are the cost to operate and 
maintain the BRS system. AWS licensees must compensate BRS licensees for 
any increased recurring costs associated with the replacement facilities 
(e.g., additional rental payments, increased utility fees) for five 
years after relocation. AWS licensees may satisfy this obligation by 
making a lump-sum payment based on present value using current interest 
rates. Additionally, the maintenance costs to the BRS licensee must be 
equivalent to the replaced system in order for the replacement system to 
be considered comparable.
    (c) AWS licensees are responsible for the relocation costs of end 
user units served by the BRS base station that is being relocated. If a 
lessee is operating

[[Page 402]]

under a BRS license, the AWS licensee shall on the throughput, 
reliability, and operating costs of facilities in use by a lessee at the 
time of relocation in determining comparable facilities for involuntary 
relocation purposes.
    (d) Twelve-month trial period. If, within one year after the 
relocation to new facilities, the BRS licensee demonstrates that the new 
facilities are not comparable to the former facilities, the AWS licensee 
must remedy the defects or pay to relocate the BRS licensee to one of 
the following: Its former or equivalent 2 GHz channels, another 
comparable frequency band, a land-line system, or any other facility 
that satisfies the requirements specified in paragraph (b) of this 
section. This trial period commences on the date that the BRS licensee 
begins full operation of the replacement system. If the BRS licensee has 
retained its 2 GHz authorization during the trial period, it must return 
the license to the Commission at the end of the twelve months.



Sec.  27.1253  Sunset provisions.

    (a) BRS licensees will maintain primary status in the 2150-2160/62 
MHz band unless and until an AWS licensee requires use of the spectrum. 
AWS licensees are not required to pay relocation costs after the 
relocation rules sunset (i.e. fifteen years from the date the first AWS 
license is issued in the band). Once the relocation rules sunset, an AWS 
licensee may require the incumbent to cease operations, provided that 
the AWS licensee intends to turn on a system within interference range 
of the incumbent, as determined by Sec.  27.1255. AWS licensee 
notification to the affected BRS licensee must be in writing and must 
provide the incumbent with no less than six months to vacate the 
spectrum. After the six-month notice period has expired, the BRS 
licensee must turn its license back into the Commission, unless the 
parties have entered into an agreement which allows the BRS licensee to 
continue to operate on a mutually agreed upon basis.
    (b) If the parties cannot agree on a schedule or an alternative 
arrangement, requests for extension will be accepted and reviewed on a 
case-by-case basis. The Commission will grant such extensions only if 
the incumbent can demonstrate that:
    (1) It cannot relocate within the six-month period (e.g., because no 
alternative spectrum or other reasonable option is available); and
    (2) The public interest would be harmed if the incumbent is forced 
to terminate operations.



Sec.  27.1254  Eligibility.

    (a) BRS licensees with primary status in the 2150-2162 MHz band as 
of June 23, 2006, will be eligible for relocation insofar as they have 
facilities that are constructed and in use as of this date.
    (b) Future licensing and modifications. After June 23, 2006, all 
major modifications to existing BRS systems in use in the 2150-2160/62 
MHz band will be authorized on a secondary basis to AWS systems, unless 
the incumbent affirmatively justifies primary status and the incumbent 
BRS licensee establishes that the modification would not add to the 
relocation costs of AWS licensees. Major modifications include the 
following:
    (1) Additions of new transmit sites or base stations made after June 
23, 2006;
    (2) Changes to existing facilities made after June 23, 2006, that 
would increase the size or coverage of the service area, or interference 
potential, and that would also increase the throughput of an existing 
system (e.g., sector splits in the antenna system). Modifications to 
fully utilize the existing throughput of existing facilities (e.g., to 
add customers) will not be considered major modifications even if such 
changes increase the size or coverage of the service area, or 
interference potential.



Sec.  27.1255  Relocation criteria for Broadband Radio Service licensees
in the 2150-2160/62 MHz band.

    (a) An AWS licensee in the 2150-2160/62 MHz band, prior to 
initiating operations from any base or fixed station that is co-channel 
to the 2150-2160/62 MHz band, must relocate any incumbent BRS system 
that is within the line of sight of the AWS licensee's base or fixed 
station. For purposes of this section, a determination of whether an

[[Page 403]]

AWS facility is within the line of sight of a BRS system will be made as 
follows:
    (1) For a BRS system using the 2150-2160/62 MHz band exclusively to 
provide one-way transmissions to subscribers, the AWS licensee will 
determine whether there is an unobstructed signal path (line of sight) 
to the incumbent licensee's geographic service area (GSA), based on the 
following criteria: use of 9.1 meters (30 feet) for the receiving 
antenna height, use of the actual transmitting antenna height and 
terrain elevation, and assumption of 4/3 Earth radius propagation 
conditions. Terrain elevation data must be obtained from the U.S. 
Geological Survey (USGS) 3-second database. All coordinates used in 
carrying out the required analysis shall be based upon use of NAD-83.
    (2) For all other BRS systems using the 2150-2160/62 MHz band, the 
AWS licensee will determine whether there is an unobstructed signal path 
(line of sight) to the incumbent licensee's receive station hub using 
the method prescribed in ``Methods for Predicting Interference from 
Response Station Transmitters and to Response Station Hubs and for 
Supplying Data on Response Station Systems. MM Docket 97-217,'' in

Clearinghouse is a neutral, independent third-party to administer the 
cost management for the transition of the 3700-4000 MHz band from the 
Fixed Satellite Service and Fixed Service to the 3.7 GHz Service.
    (8) Relocation Coordinator. A Relocation Coordinator is a third 
party that will ensure that all incumbent space station operators are 
relocating in a timely matter, and that is selected consistent with 
Sec.  27.1413. The Relocation Coordinator will have technical experience 
in understanding and working on earth stations and will manage the 
migration and filtering of incumbent earth stations of eligible space 
station operators that decline accelerated relocation payment.



Sec.  27.1412  Transition Plan.

    (a) Relocation deadlines. Eligible space station operators are 
responsible for all necessary actions to clear their transponders from 
the 3700-4000 MHz band (e.g., launching new satellites, reprogramming 
transponders, exchanging customers) and to migrate the existing services 
of incumbent earth stations in CONUS to the 4000-4200 MHz band (unless 
the incumbent earth station opts out of the formal relocation process, 
per paragraph (e) of this section), as of December 5, 2025. Eligible 
space station

[[Page 407]]

operators that fail to do so will be in violation of the conditions of 
their license authorization and potentially subject to forfeitures and 
other sanctions.
    (b) Accelerated relocation deadlines. An eligible space station 
operator shall qualify for accelerated relocation payments by completing 
an early transition of the band to the 3.7 GHz Service.
    (1) Phase I deadline. An eligible space station operator shall 
receive an accelerated relocation payment if it clears its transponders 
from the 3700-3820 MHz band and migrates all associated incumbent earth 
stations in CONUS above 3820 MHz no later than December 5, 2021 (Phase I 
deadline). To satisfy the Phase I deadline, an eligible space station 
operator must also provide passband filters to block signals from the 
3700-3820 MHz band on all associated incumbent earth stations in PEAs 1-
4, 6-10, 12-19, 21-41, and 43-50 no later than December 5, 2021 (see 
Sec.  27.6(m)). If an eligible space station operator receives an 
accelerated relocation payment for meeting this deadline, it must also 
satisfy the second early clearing deadline of December 5, 2023.
    (2) Phase II deadline. An eligible space station operator shall 
receive an accelerated relocation payment if it clears its transponders 
from the 3700-4000 MHz band and migrates incumbent earth stations in 
CONUS above 4000 MHz no later than December 5, 2023 (Phase II deadline). 
To satisfy the Phase II deadline, an eligible space station operator 
must also provide passband filters on all associated incumbent earth 
stations in CONUS no later than December 5, 2023.
    (3) Transition delays. An eligible space station operator shall not 
be held responsible for circumstances beyond their control related to 
earth station migration or filtering.
    (i) An eligible space station operator must submit a notice of any 
incumbent earth station transition delays to the Wireless 
Telecommunications Bureau within 7 days of discovering an inability to 
accomplish the assigned earth station transition task. Such a request 
must include supporting documentation to allow for resolution as soon as 
practicable and must be submitted before the accelerated relocation 
deadlines.
    (ii) [Reserved]
    (4) Responsibility for meeting accelerated relocation deadlines. An 
eligible space station operator's satisfaction of the accelerated 
relocation deadlines shall be determined on an individual basis.
    (c) Accelerated relocation election. An eligible space station 
operator may elect to receive accelerated relocation payments to 
transition the 3700-4000 MHz band to the 3.7 GHz Service according to 
the Phase I and Phase II deadlines via a written commitment by filing an 
accelerated relocation election in GN Docket No. 18-122 no later than 
May 29, 2020.
    (1) The Wireless Telecommunications Bureau will prescribe the 
precise form of such election via Public Notice no later than May 12, 
2020.
    (2) Each eligible space station operator that that makes an 
accelerated relocation election will be required, as part of its filing 
of this accelerated relocation election, to commit to paying the 
administrative costs of the Clearinghouse until the Commission awards 
licenses to the winning bidders in the auction, at which time those 
administrative costs will be repaid to those space station operators.
    (d) Transition Plan. Eligible space station operators must file with 
the Commission in GN Docket No. 18-122 no later than June 12, 2020, a 
Transition Plan that describes the actions that must be taken to clear 
transponders on space stations and to migrate and filter earth stations. 
Eligible space station operators must make any necessary updates or 
resolve any deficiencies in their individual Transition Plans by August 
14, 2020.
    (1) The Transition Plan must detail the eligible space station 
operator's individual timeline and necessary actions for clearing its 
transponders from the 3700-4000 MHz band, including:
    (i) All existing space stations with operations that will need to be 
transitioned to operations above 4000 MHz;
    (ii) The number of new satellites, if any, that the space station 
operator

[[Page 408]]

will need to launch in order to maintain sufficient capacity post-
transition, including detailed descriptions of why such new satellites 
are necessary;
    (iii) The specific grooming plan for migrating existing services 
above 4000 MHz, including the pre- and post-transition frequencies that 
each customer will occupy;
    (iv) Any necessary technology upgrades or other solutions, such as 
video compression or modulation, that the space station operator intends 
to implement;
    (v) The number and location of incumbent earth stations antennas 
currently receiving the space station operator's transmissions that will 
need to be transitioned above 4000 MHz;
    (vi) An estimate of the number and location of incumbent earth 
station antennas that will require retuning and/or repointing in order 
to receive content on new transponder frequencies post-transition; and
    (vii) The specific timeline by which the space station operator will 
implement the actions described in its plan including any commitments to 
satisfy an early clearing.
    (2) To the extent that incumbent earth stations are not accounted 
for in eligible space station operators' Transition Plans, the 
Relocation Coordinator must prepare an Earth Station Transition Plan for 
such incumbent earth stations and may require each associated space 
station operator to file the information needed for such a plan with the 
Relocation Coordinator.
    (i) Where space station operators do not elect to clear by the 
accelerated relocation deadlines and therefore are not responsible for 
earth station relocation, the Earth Station Transition Plan must provide 
timelines that ensure all earth station relocation is completed no later 
than the relocation deadline.
    (ii) The Relocation Coordinator will describe and recommend the 
respective responsibility of each party for earth station migration and 
filtering obligations in the Earth Station Transition Plan and assist 
incumbent earth stations in transitioning including, for example, by 
installing filters or hiring a third party to install such filters to 
the extent necessary.
    (e) Incumbent earth station opt-out. An incumbent earth station 
within the contiguous United States may opt out of the formal relocation 
process and accept a lump sum payment equal to the estimated reasonable 
transition costs of earth station migration and filtering, as determined 
by the Wireless Telecommunications Bureau, in lieu of actual relocation 
costs. Such an incumbent earth station is responsible for coordinating 
with the relevant space station operator as necessary and performing all 
relocation actions on its own, including switching to alternative 
transmission mechanisms such as fiber, and it will not receive further 
reimbursement for any costs exceeding the lump sum payment. An incumbent 
earth station electing to opt out must inform the appropriate space 
station operator(s) and the Relocation Coordinator that earth station 
migration and filtering will not be necessary for the relevant earth 
station site and must coordinate with operators to avoid any disruption 
of video and radio programming.
    (f) Space station status reports. On a quarterly basis, beginning 
December 31, 2020: Each eligible space station operator must provide a 
status report of its clearing efforts. Eligible space station operators 
may file joint status reports.
    (g) Certification of accelerated relocation. Each eligible space 
station operator must file a timely certification that it has completed 
the necessary clearing actions to satisfy each accelerated relocation 
deadline. The certification must be filed once the eligible space 
station operator completes its obligations but no later than the 
applicable accelerated relocation deadline. The Wireless 
Telecommunication Bureau will prescribe the form of such certification.
    (1) The Bureau, Clearinghouse, and relevant stakeholders will have 
the opportunity to review the certification of accelerated relocation 
and identify potential deficiencies. The Wireless Telecommunications 
Bureau will prescribe the form of any challenges by relevant 
stakeholders as to the validity of the certification and will establish 
the process for how such challenges will impact the incremental 
decreases in

[[Page 409]]

the accelerated relocation payment as set- forth in Sec.  27.1422(d).
    (2) If credible challenges as to the space station operator's 
satisfaction of the relevant deadline are made, the Bureau will issue a 
public notice identifying such challenges and will render a final 
decision as to the validity of the certification no later than 60 days 
from its filing. Absent notice from the Bureau of any such deficiencies 
within 30 days of the filing of the certification, the certification of 
accelerated relocation will be deemed validated.
    (h) Delegated authority. The Wireless Telecommunications Bureau is 
delegated the role of providing clarifications or interpretations to 
eligible space station operators of the Commission's orders for all 
aspects of the transition.

    A Relocation Payment Clearinghouse shall be selected and serve to 
administer the cost-related aspects of the transition in a fair, 
transparent manner, pursuant to Commission rules and oversight, to 
mitigate financial disputes among stakeholders, and to collect and 
distribute payments in a timely manner for the transition of the 3700-
4000 MHz band to the 3.7 GHz Service.
    (a) Selection process. (1) A search committee will select the 
Relocation Payment Clearinghouse. The search committee shall consist of 
member appointed by each of following nine entities: ACA Connects, 
Intelsat, SES, Eutelsat S.A., National Association Broadcasters, 
National Cable Television Association, CTIA, Competitive Carriers 
Association, and WISPA.
    (2) The search committee shall convene no later than June 22, 2020 
and shall notify the Commission of the detailed selection criteria for 
the position of Relocation Payment Clearinghouse no later than June 1, 
2020. Such criteria must be consistent with the qualifications, roles, 
and duties of the Relocation Payment Clearinghouse specified in this 
subpart. The Wireless Telecommunications Bureau (Bureau) is directed, on 
delegated authority, to issue a Public Notice notifying the public that 
the search committee has published criteria, outlining submission 
requirements, and providing the closing dates for the selection of the 
Relocation Payment Clearinghouse and source (i.e., web page).

[[Page 411]]

    (3) The search committee should proceed by consensus; however, if a 
vote on selection of a Relocation Payment Clearinghouse is required, it 
shall be by a majority.
    (4) In the event that the search committee fails to select a 
Relocation Payment Clearinghouse and to notify the Commission by July 
31, 2020, the search committee will be dissolved without further action 
by the Commission. In the event that the search committee fails to 
select a Clearinghouse and to notify the Commission by July 31, 2020, 
two of the nine members of the search committee will be dropped 
therefrom by lot, and the remaining seven members of the search 
committee shall select a Clearinghouse by majority vote by August 14, 
2020.
    (5) During the course of the Relocation Payment Clearinghouse's 
tenure, the Commission will take such measures as are necessary to 
ensure timely compliance, including, should it become necessary, issuing 
subsequent public notices to select new Relocation Payment 
Clearinghouses(s).
    (b) Selection criteria. (1) The Relocation Payment Clearinghouse 
must be a neutral, independent entity with no conflicts of interest 
(organizational or personal) on the part of the organization or its 
officers, directors, employees, contractors, or significant 
subcontractors.
    (i) Organizational conflicts of interest means that because of other 
activities or relationships with other entities, the Relocation Payment 
Clearinghouse, its contractors, or significant subcontractors are unable 
or potentially unable to render impartial services, assistance or 
advice; the Relocation Payment Clearinghouse's objectivity in performing 
its function is or might be otherwise impaired; or the Relocation 
Payment Clearinghouse might gain an unfair competitive advantage.
    (ii) Personal conflict of interest means a situation in which an 
employee, officer, or director of the Relocation Payment Clearinghouse, 
the Relocation Payment Clearinghouse's contractors or significant 
subcontractors has a financial interest, personal activity, or 
relationship that could impair that person's ability to act impartially 
and in the best interest of the transition when performing their 
assigned role, or is engaged in self-dealing.
    (2) The Relocation Payment Clearinghouse must be able to demonstrate 
that it has the requisite expertise to perform the duties required, 
which will include collecting and distributing relocation and 
accelerated relocation payments, auditing incoming and outgoing 
estimates, mitigating cost disputes among parties, and generally acting 
as clearinghouse.
    (3) The search committee should ensure that the Relocation Payment 
Clearinghouse meets relevant best practices and standards in its 
operation to ensure an effective and efficient transition. First, the 
Relocation Payment Clearinghouse should be required, in administering 
the transition, to:
    (i) Engage in strategic planning and adopt goals and metrics to 
evaluate its performance;
    (ii) Adopt internal controls for its operations;
    (iii) Utilize enterprise risk management practices; and
    (iv) Use best practices to protect against improper payments and to 
prevent fraud, waste and abuse in its handling of funds. The Relocation 
Payment Clearinghouse must be required to create written procedures for 
its operations, using the Government Accountability Office's Green Book 
to serve as a guide in satisfying such requirements.
    (4) The search committee must also ensure that the Relocation 
Payment Clearinghouse adopts robust privacy and data security best 
practices in its operations, given that it will receive and process 
information critical to ensuring a successful and expeditious 
transition.
    (i) When the prohibition in Sec.  1.2105(c) of this chapter applies 
to competitive bidding for licenses in the 3.7 GHz service, the 
Relocation Payment Clearinghouse must make real time disclosures of the 
content and timing of and the parties to communications, if any, from or 
to applicants to participate in the competitive bidding, as defined by 
Sec.  1.2105(c)(5)(i) of this chapter.
    (ii) The Relocation Payment Clearinghouse should also comply with, 
on

[[Page 412]]

an ongoing basis, all applicable laws and Federal Government guidance on 
privacy and information security requirements such as relevant 
provisions in the Federal Information Security Management Act, National 
Institute of Standards and Technology publications, and Office of 
Management and Budget guidance.
    (iii) The Relocation Payment Clearinghouse must hire a third-party 
firm to independently audit and verify, on an annual basis, the 
Relocation Payment Clearinghouse's compliance with privacy and 
information security requirements and to provide recommendations based 
on any audit findings; to correct any negative audit findings and adopt 
any additional practices suggested by the auditor; and to report the 
results to the Bureau.
    (c) Reports and information. (1) The Relocation Payment 
Clearinghouse must provide quarterly reports that detail the status of 
reimbursement funds available for clearing obligations, the relocation 
and accelerated relocation payments issued, the amounts collected from 
overlay licensees, and any certifications filed by incumbents. The 
reports must account for all funds spent to transition the 3.7 GHz 
Service Band, including the Relocation Payment Clearinghouse's own 
expenses, e.g., salaries and fees paid to law firms, accounting firms, 
and other consultants. The report shall include descriptions of any 
disputes and the manner in which they were resolved.
    (2) The Relocation Payment Clearinghouse shall provide to the Office 
of the Managing Director and the Wireless Telecommunications Bureau, by 
March 1 of each year, an audited statement of funds expended to date, 
including salaries and expenses of the Clearinghouse.
    (3) The Relocation Clearing House shall provide to the Wireless 
Telecommunications Bureau additional information upon request.



Sec.  27.1415  Documentation of expenses.

    Parties seeking reimbursement of compensable relocation costs must 
document their actual expenses and the Relocation Payment Clearinghouse, 
or a third-party on behalf of the Relocation Payment Clearinghouse, may 
conduct audits of entities that receive reimbursements. Entities 
receiving reimbursements must make available all relevant documentation 
upon request from the Relocation Payment Clearinghouse or its 
contractor.



Sec.  27.1416  Reimbursable costs.

    (a) Determining reimbursable costs. The Relocation Payment 
Clearinghouse shall review reimbursement requests to determine whether 
they are reasonable and to ensure they comply with the requirements 
adopted in this sub-part. The Relocation Payment Clearinghouse shall 
give parties the opportunity to supplement any reimbursement claims that 
the Relocation Payment Clearinghouse deems deficient. Reimbursement 
submissions that fall within the estimated range of costs in the cost 
category schedule issued by the Wireless Telecommunications Bureau shall 
be presumed reasonable. If the Relocation Payment Clearinghouse 
determines that the amount sought for reimbursement is unreasonable, it 
shall notify the party of the amount it deems eligible for 
reimbursement. The Wireless Telecommunications Bureau shall make further 
determinations related to reimbursable costs, as necessary, throughout 
the transition process.
    (b) Payment procedures. Following a determination of the 
reimbursable amount, the Relocation Payment Clearinghouse shall 
incorporate approved claims into invoices, which it shall issue to each 
licensee indicating the amount to be paid. The Relocation Payment 
Clearinghouse shall pay approved claims within 30 days of invoice 
submission. The Relocation Payment Clearinghouse shall also include its 
own reasonable costs in the invoices.



Sec.  27.1417  Reimbursement fund.

    The Relocation Payment Clearinghouse will establish and administer 
an account that will fund the costs for the transition of this band to 
the 3.7 GHz Service after an auction for the 3.7 GHz Service concludes. 
Licensees in the 3.7 GHz Service shall pay their pro rata share of six 
months' worth of estimated transition costs into a reimbursement fund, 
administered by the Relocation Payment Clearinghouse,

[[Page 413]]

shortly after the auction and then every six months until the transition 
is complete. The Relocation Payment Clearinghouse shall draw from the 
reimbursement fund to pay approved, invoiced claims, consistent with 
Sec.  27.1418. If the reimbursement fund does not have sufficient funds 
to pay approved claims before a six-month replenishment, the Relocation 
Payment Clearinghouse shall provide 3.7 GHz Service licensees with 30 
days' notice of the additional pro rata shares they must contribute. At 
the end of the transition, the Relocation Payment Clearinghouse shall 
refund any unused amounts to 3.7 GHz Service licensees according to 
their pro rata shares.



Sec.  27.1418  Payment obligations.

    (a) Each eligible space station operator is responsible for the 
payment of its own satellite transition costs until the auction winners 
have been announced.
    (b) Licensees in the 3.7 GHz Service shall pay their pro rata share 
of:
    (1) The reasonable costs of the Relocation Payment Clearinghouse 
and, in the event the Wireless Telecommunications Bureau selects the 
Relocation Coordinator, the services of the Relocation Coordinator and 
its staff;
    (2) The actual relocation costs, provided that they are not 
unreasonable, for eligible space station operators and incumbent fixed 
service licensees; the actual transition costs, provided they are not 
unreasonable, associated with the necessary migration and filtering of 
incumbent earth stations;
    (3) Any lump sum payments, if elected by incumbent earth station 
operators in lieu of actual relocation costs; and
    (4) Specified accelerated relocation payments for space station 
operators that clear on an accelerated timeframe. Licensees in the 3.7 
GHz Service shall be responsible for the full costs of space station 
transition, the Relocation Payment Clearinghouse, and, if selected and 
established by the Wireless Telecommunications Bureau, the Relocation 
Coordinator, based on their pro rata share of the total auction bids of 
each licensee's gross winning bids in the auction overall; they shall be 
responsible for incumbent earth station and incumbent fixed service 
transition costs in a Partial Economic Area based on their pro rata 
share of the total gross bids for that Partial Economic Area.
    (c) Following the auction, and every six months until the close of 
the transition, licensees in the 3.7 GHz Service shall submit their 
portion of estimated transition costs to a reimbursement fund, and the 
Relocation Payment Clearinghouse will reimburse parties incurring 
transition costs. If actual costs exceed estimated costs, the Relocation 
Payment Clearinghouse shall perform a true-up for additional funds from 
3.7 GHz Service licensees.
    (d) If 3.7 GHz band license is relinquished to the Commission prior 
to all relocation cost reimbursements and accelerated relocation 
payments being paid, the remaining payments will be distributed among 
other similarly situated 3.7 GHz band licensees. If a new license is 
issued for the previously relinquished rights prior to final payments 
becoming due, the new 3.7 GHz band licensee will be responsible for the 
same pro rata share of relocation costs and accelerated relocation 
payments as the initial 3.7 GHz band license. If a 3.7 GHz band licensee 
sells its rights on the secondary market, the new 3.7 GHz band licensee 
will be obligated to fulfill all payment obligations associated with the 
license.



Sec.  27.1419  Lump sum payment for earth station opt out.

    The Wireless Telecommunications Bureau shall announce a lump sum 
that will be available per each incumbent earth station that elects to 
opt out from the formal relocation process, per Sec.  27.1412(e), as 
well as the process for electing lump sum payments. Incumbent earth 
station owners must make the lump sum payment election no later than 30 
days after the Bureau announces the lump sum payment amounts, and must 
indicate whether each incumbent earth station for which it elects the 
lump sum payment will be transitioned to the upper 200 megahertz in 
order to maintain C-band services or will discontinue C-band services.

[[Page 414]]



Sec.  27.1420  Cost-sharing formula.

    (a) For space station transition and Relocation Payment 
Clearinghouse costs, and in the event the Wireless Telecommunications 
Bureau selects a Relocation Coordinator pursuant to Sec.  27.1413(a), 
Relocation Coordinator costs, the pro rata share of each flexible-use 
licensee will be the sum of the final clock phase prices (P) for the set 
of all license blocks that a bidder wins divided by the total final 
clock phase prices for all N license blocks sold in the auction. To 
determine a licensee's reimbursement obligation (RO), that pro rata 
share would then be multiplied by the total eligible reimbursement costs 
(RC). Mathematically, this is represented as:
[GRAPHIC] [TIFF OMITTED] TR23AP20.008

    (b) For incumbent earth stations and fixed service incumbent 
licensee transition costs, a flexible-use licensee's pro rata share will 
be determined on a PEA-specific basis, based on the final clock phase 
prices for the license blocks it won in each PEA. To calculate the pro 
rata share for incumbent earth station transition costs in a given PEA, 
the same formula identified in Sec.  27.1412(a) will be used, except I 
is the set of licenses a bidder won in the PEA, N is the total blocks 
sold in the PEA and RC is the PEA-specific earth station and fixed 
service relocation costs.
    (c) For the Phase I accelerated relocation payments, the pro rata 
share of each flexible use licensee of the 3.7 to 3.8 MHz in the 46 PEAs 
that are cleared by December 5, 2021, will be the sum of the final clock 
phase prices (P) that the licensee won divided by the total final clock 
phase prices for all M license blocks sold in those 46 PEAs. To 
determine a licensee's RO the pro rata share would then be multiplied by 
the total accelerated relocation payment due for Phase I, A1. 
Mathematically, this is represented as:
[GRAPHIC] [TIFF OMITTED] TR23AP20.009

    (d) For Phase II accelerated relocation payments, the pro rata share 
of each flexible use licensee will be the sum of the final clock phase 
prices (P) that the licensee won in the entire auction, divided by the 
total final clock phase prices for all N license blocks sold in the 
auction. To determine a licensee's RO the pro rata share would then be 
multiplied by the total accelerated relocation payment due for Phase II, 
A2. Mathematically, this is represented as:
[GRAPHIC] [TIFF OMITTED] TR23AP20.010

Sec.  27.1421  Disputes over costs and cost-sharing.

    (a) Parties disputing a cost estimate, cost invoice, or payment or 
cost-sharing obligation must file an objection with the Relocation 
Payment Clearinghouse.
    (b) The Relocation Payment Clearinghouse may mediate any disputes 
regarding cost estimates or payments that may arise in the course of 
band reconfiguration; or refer the disputant parties to alternative 
dispute resolution fora.
    (1) Any dispute submitted to the Relocation Payment Clearinghouse, 
or other mediator, shall be decided within 30 days after the Relocation 
Payment Clearinghouse has received a submission by one party and a 
response from the other party.
    (2) Thereafter, any party may seek expedited non-binding 
arbitration, which must be completed within 30 days of the recommended 
decision or advice of the Relocation Payment Clearinghouse or other 
mediator.
    (3) The parties will share the cost of this arbitration if it is 
before the Relocation Payment Clearinghouse.
    (c) Should any issues still remain unresolved, they may be referred 
to the Bureau within ten days of recommended decision or advice of the 
Relocation Payment Clearinghouse or other mediator and any decision of 
the Relocation Payment Clearinghouse can be appealed to the Chief of the 
Bureau.
    (1) When referring an unresolved matter, the Relocation Payment 
Clearinghouse shall forward the entire record on any disputed issues, 
including such dispositions thereof that the Relocation Payment 
Clearinghouse has considered.
    (2) Upon receipt of such record and advice, the Bureau will decide 
the disputed issues based on the record submitted. The Bureau is 
directed to resolve such disputed issues or designate them for an 
evidentiary hearing before an Administrative Law Judge. If the Bureau 
decides an issue, any party to the dispute wishing to appeal the 
decision may do so by filing with the Commission, within ten days of the 
effective date of the initial decision, a Petition for de novo review; 
whereupon the matter will be set for an evidentiary hearing before an 
Administrative Law Judge.
    (3) Parties seeking de novo review of a decision by the Bureau are 
advised that, in the course of the evidentiary hearing, the Commission 
may require complete documentation relevant to any disputed matters; 
and, where necessary, and at the presiding judge's discretion, require 
expert engineering, economic or other reports or testimony. Parties may 
therefore wish to consider possibly less burdensome and expensive 
resolution of their disputes through means of alternative dispute 
resolution.



Sec.  27.1422  Accelerated relocation payment.

    (a) Eligible space station operators that meet the applicable early-
clearing benchmark(s), as confirmed in their Certification of 
Accelerated Relocation set-forth in Sec.  27.1412(g), will be eligible 
for their respective accelerated relocation payment.
    (b) The Relocation Payment Clearinghouse will distribute the 
accelerated relocation payments accordingly:

    (c) The Relocation Payment Clearinghouse shall promptly notify 3.7 
GHz Service licensees following validation of the certification of 
accelerated relocations as set-forth in Section 27.1412(g). 3.7 GHz 
Service licensees shall pay the accelerated relocation payments to the 
Clearinghouse within 60 days of the notice that eligible space station 
operators have met their respective accelerated clearing benchmark. The 
Clearinghouse shall disburse accelerated relocation payments to relevant 
space station operators within seven days of receiving the payment from 
overlay licensees.
    (d) For eligible space station operators that fail to meet either 
the Phase I or Phase II benchmarks as of the relevant accelerated

Sec.  27.1423  Protection of incumbent operations.

    (a) To protect incumbent earth stations from out-of-band emissions 
from fixed stations, base stations and mobiles, the power flux density 
(PFD) of any emissions within the 4000-4200 MHz band must not exceed -
124 dBW/m\2\/MHz as measured at the earth station antenna.
    (b) To protect incumbent earth stations from blocking, the power 
flux density (PFD) of any emissions within the 3700-3980 MHz band must 
not exceed -16 dBW/m\2\/MHz as measured at the earth station antenna.
    (c) All 3.7 GHz Service licensees, prior to initiating operations 
from any base or fixed station, must coordinate cochannel frequency 
usage with all incumbent Telemetry, Tracking, and Command (TT&C) earth 
stations within a 70 km radius. The licensee must ensure that the 
aggregated power from its operations meets an interference to noise 
ratio (I/N) of -6 dB to the TT&C earth station receiver. A base 
station's operation will be defined as cochannel when any of the 3.7 GHz 
Service licensee's authorized frequencies are separated from the center 
frequency of the TT&C earth station by less than 150% of the maximum 
emission bandwidth in use by the TT&C earth station.
    (d) All 3.7 GHz Service licensees operating on an adjacent channel 
to an incumbent TT&C earth station must ensure that the aggregated power 
from its operations meets an interference to noise ratio (I/N) of -6 dB 
to the TT&C earth station receiver.
    (e) To protect incumbent TT&C earth stations from blocking, the 
power flux density (PFD) of any emissions within the 3700-3980 MHz band 
must not exceed -16 dBW/m\2\/MHz as measured at the TT&C earth station 
antenna.



Sec.  27.1424  Agreements between 3.7 GHz Service licensees and C-Band
earth station operators.

    The PFD limits in Sec.  27.1423 may be modified by the private 
agreement of licensees of 3.7 GHz Service and entities operating earth 
stations in the 4000-4200 MHz band or TT&C operations in the 3700-3980 
MHz band. A licensee of the 3.7 GHz Service who is a party to such an 
agreement must maintain a copy of the agreement in its station files and 
disclose it, upon request, to prospective license assignees, 
transferees, or spectrum lessees, and to the Commission.

or demonstrate how it will provide interference protection to, covered 
incumbent licensees collectively holding licenses in the broadband 
segment for at least 90% of the site-channels in the county and within 
70 miles of the county boundary, and geographically licensed channels 
where the license area completely or partially overlaps the county. To 
provide interference protection, an applicant may:
    (i) Protect site-based covered incumbent(s) through compliance with 
minimum spacing criteria set forth in Sec.  90.621(b) of this chapter;
    (ii) Protect site-based covered incumbent(s) through new or existing

private contractual agreement.
    (3) If any site of a complex system is located within the county 
and/or within 70 miles of the county boundary, an applicant must either 
hold the license for that site or reach an agreement to acquire, 
relocate, or protect it in order to demonstrate eligibility.
    (4) The applicant may use its current 900 MHz holdings in the 
narrowband segment to relocate covered incumbents. Spectrum used for the 
purpose of relocating incumbent(s) may not exceed the incumbent's 
current spectrum holdings in the relevant county, unless additional 
channels are necessary to achieve equivalent coverage and/or capacity.
    (b) Application. (1) Applications must be filed in accordance with 
part 1, subpart F of this chapter.
    (2) An applicant for a 900 MHz broadband license must submit with 
its application an Eligibility Certification that:

within 70 miles of the county boundary and/or evidence that it holds 
licenses for the site-channels and/or geographically licensed channels.
    (C) Any rule waivers or other actions necessary to implement an 
agreement with a covered incumbent; and
    (D) Such additional information as may be required.
    (iv) A certification from an FCC-certified frequency coordinator 
that the Transition Plan's representations can be implemented consistent 
with Commission rules. The certification must establish that the 
relocations proposed therein take into consideration all relevant 
covered incumbents and are consistent with the existing part 90 
interference protection criteria if the covered incumbent is site-based, 
and include any private contractual agreements between the prospective 
broadband licensee and a geographically-licensed covered incumbent.
    (4) Applicants seeking to transition multiple counties may 
simultaneously file a single Transition Plan with each of its county-
based applications.
    (c) Anti-windfall provisions. (1) The applicant must return to the 
Commission all of its licensed 900 MHz SMR and B/ILT spectrum, up to six 
megahertz, for the county in which it seeks a broadband license. The 
applicant will be required to file, within 15 days of filing its 
broadband license application, an application(s) to cancel all of its 
900 MHz SMR and B/ILT spectrum, up to six megahertz, conditioned upon 
Commission grant of its application.
    (2) If the applicant relinquishes less than six megahertz of 
spectrum in accordance with paragraph (c)(1) of this section, then the 
applicant must remit an anti-windfall payment prior to the grant of the 
900 MHz broadband license. Payment must be made through a monetary 
payment to the U.S. Treasury.



Sec.  27.1504  Mandatory relocation.

    (a) Subject to paragraph (b) of this section, broadband licensees 
may require mandatory relocation from the broadband segment covered 
incumbents' remaining site-channels in a given county and within 70 
miles of the county boundary, and geographically licensed channels where 
the license area completely or partially overlaps the county, that were 
not covered by Sec.  27.1503(a)(2).
    (b) Complex systems are exempt from mandatory relocation. To qualify 
as exempt from mandatory relocation, a complex system must have at least 
one site (of its 45 or more functionally integrated sites) located 
within the county license area or within 70 miles of the county 
boundary.
    (c) A broadband licensee seeking to relocate a covered incumbent 
pursuant to this section is required to pay all reasonable relocation 
costs, including providing the relocated covered incumbent with 
comparable facilities. To be comparable, the replacement system provided 
to a covered incumbent during a mandatory relocation must be at least 
equivalent to the existing 900 MHz system with respect to the following 
four factors:
    (1) System;
    (2) Capacity;
    (3) Quality of service; and
    (4) Operating costs.
    (d) Having met the 90% success threshold, a 900 MHz broadband 
licensee seeking to trigger the mandatory relocation process shall serve 
notice on applicable covered incumbent(s).
    (e) Following the service of notice, a 900 MHz broadband licensee 
may request information from the covered incumbent reasonably required 
to craft its offer of comparable facilities.
    (f) We expect all parties to negotiate with the utmost ``good 
faith'' in the negotiation process. Factors relevant to a ``good-faith'' 
determination include:
    (1) Whether the party responsible for paying the cost of band 
reconfiguration has made a bona fide offer to relocate the incumbent to 
comparable facilities;
    (2) The steps the parties have taken to determine the actual cost of 
relocation to comparable facilities; and
    (3) Whether either party has unreasonably withheld information, 
essential to the accurate estimation of relocation costs and procedures, 
requested by the other party.

[[Page 420]]

    (g) A party seeking Commission resolution of a dispute must submit 
in writing to the Chief, Wireless Telecommunications Bureau:
    (1) The name, address, telephone number, and email address of the 
900 MHz broadband licensee or covered incumbent making the allegation;
    (2) The name of the 900 MHz broadband licensee or covered incumbent 
about which the allegation is made;
    (3) A complete statement of the facts supporting the broadband 
licensee's or incumbent's claim; and
    (4) The specific relief sought.
    (h) If an incumbent fails to negotiate in good faith, its facilities 
may be mandatorily relocated, and its license modified accordingly by 
the Commission pursuant to section 316 of the Act. If the Wireless 
Telecommunications Bureau finds bad faith on the part of the broadband 
licensee, the broadband licensee may lose the right to relocate the 
incumbent or the Wireless Telecommunications Bureau may refer the matter 
to the Enforcement Bureau for action (which could include a range of 
sanctions, such as imposition of forfeitures).



Sec.  27.1505  Performance requirements.

    (a) 900 MHz broadband licensees shall demonstrate compliance with 
performance requirements by filing a construction notification with the 
Commission, within 15 days of the expiration of the applicable 
benchmark, in accordance with the provisions set forth in Sec.  1.946(d) 
of this chapter.
    (1) The licensee must certify whether it has met the applicable 
performance requirements. The licensee must file a description and 
certification of the areas for which it is providing service. The 
construction notifications must include electronic coverage maps and 
supporting technical documentation regarding the type of service it is 
providing for each licensed area within its service territory and the 
type of technology used to provide such service, and certify the 
accuracy of such documentation. Supporting documentation must include 
the assumptions used to create the coverage maps, including the 
propagation model and the signal strength necessary to provide reliable 
service with the licensee's technology.
    (2) To demonstrate compliance with the population coverage 
requirement, licensees shall use the most recently available decennial 
U.S. Census Bureau data at the time of measurement and shall base their 
measurements of population served on areas no larger than the Census 
Tract level. The population within a specific Census Tract (or other 
acceptable identifier) will be deemed served by the licensee only if it 
provides reliable signal coverage to and offers service within the 
specific Census Tract (or other acceptable identifier). To the extent 
the Census Tract (or other acceptable identifier) extends beyond the 
boundaries of a license area, a licensee with authorizations for such 
areas may include only the population within the Census Tract (or other 
acceptable identifier) towards meeting the performance requirement of a 
single, individual license.
    (b) A 900 MHz broadband licensee must meet either a population 
coverage requirement or geographic coverage as follows:
    (1) Population metric. (i) A 900 MHz broadband licensee shall 
provide reliable signal coverage and offer broadband service to at least 
45% of the population in its license area within six years of license 
grant.
    (ii) A 900 MHz broadband licensee shall provide reliable signal 
coverage and offer broadband service to at least 80% of the population 
in its license area within 12 years of license grant.
    (2) Geographic coverage. Alternatively, a 900 MHz broadband licensee 
may:
    (i) Demonstrate it provides reliable signal coverage and offers 
broadband service covering at least 25% of the geographic license area 
within six years of license grant.
    (ii) Demonstrate it provides reliable signal coverage and offers 
broadband service covering at least 50% of the geographic license area 
within twelve years of license grant.
    (c) Penalties. (1) If a 900 MHz broadband licensee fails to meet the 
first performance benchmark, we require the licensee to meet the final 
performance benchmark two years sooner (i.e., at 10 years into the 
license

[[Page 421]]

term) and reduce the license term from 15 years to 13 years.
    (2) If a 900 MHz broadband licensee fails to meet the final 
performance benchmark, its authorization for that license area will 
terminate automatically without Commission action.
    (d) License renewal. After satisfying the 12-year, final performance 
benchmark, a licensee must continue to provide coverage and offer 
broadband service at or above that level for the remaining three years 
of the 15-year license term in order to warrant license renewal.



Sec.  27.1506  Frequencies.

    The 897.5-900.5 MHz and 936.5-939.5 MHz band segments are available 
for licensing with an authorized bandwidth up to 3 megahertz paired 
channels. The 897.5-900.5 MHz segment must only be used for uplink 
transmissions. The 936.5-939.5 MHz segments must only be used for 
downlink transmissions.



Sec.  27.1507  Effective radiated power limits for 900 MHz broadband
systems.

    (a) Maximum ERP. The power limits specified in this section are 
applicable to operations in areas more than 110 km (68.4 miles) from the 
U.S./Mexico border and 140 km (87 miles) from the U.S./Canada border.
    (1) General limit. (i) The ERP for base and repeater stations must 
not exceed 400 watts/megahertz power spectral density (PSD) per sector 
and an antenna height of 304 m height above average terrain (HAAT), 
except that antenna heights greater than 304 m HAAT are permitted if 
power levels are reduced below 400 watts/megahertz ERP in accordance 
with Table 1 of this section.
    (ii) Provided that they also comply with paragraphs (b) and (c) of 
this section, licensees are permitted to operate base and repeater 
stations with up to a maximum ERP of 1000 watts/megahertz power spectral 
density (PSD) per sector and an antenna height of 304 m height above 
average terrain (HAAT), except that antenna heights greater than 304 m 
HAAT are permitted if power levels are reduced below 1000 watts/
megahertz ERP in accordance with Table 2 of this section.
    (2) Rural areas. For systems that are located in counties with 
population densities of 100 persons or fewer per square mile, based upon 
the most recently available population statistics from the Bureau of the 
Census:
    (i) The ERP for base and repeater stations must not exceed 800 
watts/megahertz power spectral density (PSD) per sector and an antenna 
height of 304 m height above average terrain (HAAT), except that antenna 
heights greater than 304 m HAAT are permitted if power levels are 
reduced below 800 watts/megahertz ERP in accordance with Table 3 of this 
section.
    (ii) Provided that they also comply with paragraphs (b) and (c) of 
this section, base and repeater stations may operate with up to a 
maximum ERP of 2000 watts/megahertz power spectral density (PSD) per 
sector and an antenna height of 304 m height above average terrain 
(HAAT), except that antenna heights greater than 304 m HAAT are 
permitted if power levels are reduced below 2000 watts/megahertz ERP in 
accordance with Table 4 of this section.
    (3) Mobile, control and auxiliary test stations. Mobile, control and 
auxiliary test stations must not exceed 10 watts ERP.
    (4) Portable stations. Portable stations must not exceed 3 watts 
ERP.
    (b) Power flux density (PFD). Each 900 MHz broadband base or 
repeater station that exceeds the ERP limit of paragraph (a)(1)(i) or 
(a)(2)(i) of this section must be designed and deployed so as not to 
exceed a modeled PFD of 3000 microwatts/m\2\/MHz over at least 98% of 
the area within 1 km of the base or repeater station antenna, at 1.6 
meters above ground level. To ensure compliance with this requirement, 
the licensee must perform predictive modeling of the PFD values within 
at least 1 km of each base or repeater station antenna prior to 
commencing such operations and, thereafter, prior to making any site 
modifications that may increase the PFD levels around the base or 
repeater station. The modeling must take into consideration terrain and 
other local conditions and must use good engineering practices for the 
900 MHz band.

[[Page 422]]

    (c) Power measurement. Measurement of 900 MHz broadband base 
transmitter and repeater ERP must be made using an average power 
measurement technique. Power measurements for base transmitters and 
repeaters must be made in accordance with either of the following:
    (1) A Commission-approved average power technique (see FCC 
Laboratory's Knowledge Database); or
    (2) For purposes of this section, peak transmit power must be 
measured over an interval of continuous transmission using 
instrumentation calibrated in terms of an rms-equivalent voltage. The 
measurement results shall be properly adjusted for any instrument 
limitations, such as detector response times, limited resolution 
bandwidth capability when compared to the emission bandwidth, 
sensitivity, etc., so as to obtain a true peak measurement for the 
emission in question over the full bandwidth of the channel.
    (d) PAR limit. The peak-to-average ratio (PAR) of the transmission 
must not exceed 13 dB.
    (e) Height-power limit. As specified in paragraph (a) of this 
section, the following tables specify the maximum base station power for 
antenna heights above average terrain (HAAT) that exceed 304 meters.

Sec.  27.1508  Field strength limit.

    The predicted or measured median field strength must not exceed 40 
dB[micro]V/m at any given point along the geographic license boundary, 
unless the affected licensee agrees to a different field strength. This 
value applies to both the initially offered service areas and to 
partitioned service areas.



Sec.  27.1509  Emission limits.

    The power of any emission outside a licensee's frequency band(s) of 
operation shall be attenuated below the transmitter power (P) in watts 
by at least the following amounts:
    (a) For 900 MHz broadband operations in 897.5-900.5 MHz band by at 
least 43 + 10 log (P) dB.
    (b) For 900 MHz broadband operations in the 936.5-939.5 MHz band, by 
at least 50 + 10 log (P) dB.
    (c) Compliance with the provisions of paragraphs (a) and (b) of this 
section is based on the use of measurement instrumentation employing a 
resolution bandwidth of 100 kHz or greater. However, in the 100 kHz 
bands immediately outside and adjacent to the licensee's band, a 
resolution bandwidth of at least 1 percent of the emission bandwidth of 
the fundamental emission of the transmitter may be employed. The 
emission bandwidth is defined as the width of the signal between two 
points, one below the carrier center frequency and one above the carrier 
center frequency, outside of which all emissions are attenuated at least 
26 dB below the transmitter power.
    (d) The measurements of emission power can be expressed in peak or

Sec.  27.1602  Incumbent Federal operations.

    Regarding incumbent Federal operations in the 3450-3550 MHz band, 
3.45 GHz Service licensees must comply with footnote US431B of the Table 
of Frequency Allocations in 47 CFR 2.106.



Sec.  27.1603  Coordination procedures.

    (a) Coordination requirement. Prior to operation of any 3.45 GHz 
Service license in a Cooperative Planning Area or Periodic Use Area, a 
3.45 GHz Service licensee must successfully coordinate such operation 
with any Federal incumbents in the Cooperative Planning Area or Periodic 
Use Area. The coordination procedures contained in this section shall 
apply unless the 3.45 GHz Service licensee and the Federal incumbent(s) 
have reached a mutually acceptable operator-to-operator coordination 
agreement that provides otherwise.
    (b) Informal discussions. Before a 3.45 GHz Service licensee submits 
a formal coordination request, it may share and discuss draft proposals 
with Federal incumbent coordination staff. These discussions are 
voluntary, informal, and non-binding and can begin at any time.
    (c) Formal coordination. The 3.45 GHz Service licensee shall 
initiate coordination by formally requesting access to operate within a 
Cooperative Planning Area and/or Periodic Use Area directly through the 
Department of Defense's online portal.
    (d) Initiation, timing, and affirmative concurrence. A 3.45 GHz 
Service licensee must initiate a formal coordination request through the 
online portal provided by the Department of Defense. Unless otherwise 
agreed between a 3.45 GHz Service licensee and the relevant Federal 
incumbent(s), no formal coordination requests may be submitted until 
nine (9) months after the date of the auction closing Public Notice. 
3.45 GHz Service licensees may request informal discussions (through the 
point of contact identified in the applicable Transition Plan) during 
this nine-month time period. Unless otherwise agreed to in writing, the 
requirement to reach a coordination arrangement is satisfied only by 
obtaining the affirmative concurrence of the relevant Federal 
incumbent(s) via the portal. The requirement of this paragraph (d) is 
not satisfied by omission.
    (e) Submission information. To submit a formal coordination request, 
the 3.45 GHz Service licensee must include information about the 
technical characteristics for the 3.45 GHz Service base stations and 
associated mobile units relevant to operation within the Cooperative 
Planning Area and/or Periodic Use Area. This information should be 
provided in accordance with the instructions provided in the portal 
user's guide provided by the Department of Defense. 3.45 GHz Service 
licensees must prioritize their deployments in the Cooperative Planning 
Area for each Federal incumbent when submitting a formal coordination 
request. If a 3.45 GHz Service licensee is seeking to coordinate with 
multiple systems or multiple locations of operation controlled by one 
Federal incumbent, the licensee must specify the order in which it 
prefers the Federal incumbent process the request (i.e., the order of 
systems or geographic locations).
    (f) Coordination analysis. If a 3.45 GHz Service licensee has 
questions about the result of a coordination request, it may contact the 
Federal incumbent to propose network design modifications to help 
address issues raised by the Federal incumbent. Once the 3.45 GHz 
Service licensee has revised its network design, it must resubmit a 
formal

[[Page 425]]

coordination request, and the 3.45 GHz Service formal coordination 
process begins again.
    (g) Interference resolution process. In instances of identified 
harmful interference occurring between a Federal and non-Federal 
operator not otherwise addressed by the coordination procedures or 
operator-to-operator agreements, the 3.45 GHz Service licensee shall 
first attempt to resolve the interference directly. If that effort is 
unsuccessful, the 3.45 GHz Service licensee, if adversely affected may 
escalate the matter to the Commission.



Sec.  27.1604  Reimbursement of relocation expenses of non-Federal
radiolocation incumbents.

    (a) Relocation reimbursement contribution. Each entity granted an 
initial license (not a renewal) in the 3.45 GHz Service (Licensee) must 
pay a pro rata portion to reimburse the costs incurred by authorized 
non-Federal, secondary radiolocation licensees for relocating from the 
3.3-3.55 GHz band. These costs include the cost of a clearinghouse's 
administration of the reimbursement, which the radiolocation licensees 
will pay initially and include in their reimbursable costs.
    (b) Pro rata share. A Licensee's pro rata share of relocation costs 
will be determined by dividing the total actual costs of such 
relocation, as approved by the clearinghouse selected pursuant to Sec.  
27.1605, by the total number of 3.45 GHz Service licenses granted, 
multiplied by the number of such licenses the Licensee will hold.
    (c) Timing of payment. A Licensee's relocation reimbursement 
contribution share must be paid to the clearinghouse by the date(s) and 
subject to procedures specified by public notice.



Sec.  27.1605  Reimbursement clearinghouse.

    (a) The clearinghouse ultimately selected shall determine the 
reimbursement obligations of each Licensee pursuant to Sec.  27.1604.
    (1) The clearinghouse must be a must be a neutral, independent 
entity with no conflicts of interest (as defined in Sec.  27.1414(b), on 
the part of the organization or its officers, directors, employees, 
contractors, or significant subcontractors.
    (2) The clearinghouse must be able to demonstrate that it has the 
requisite expertise to perform the duties required, which will include 
collecting and distributing reimbursement payments, auditing incoming 
and outgoing estimates, mitigating cost disputes among parties, and 
generally acting as a clearinghouse.
    (3) The clearinghouse must comply with, on an ongoing basis, all 
applicable laws and Federal Government guidance on privacy and 
information security requirements such as relevant provisions in the 
Federal Information Security Management Act, National Institute of 
Standards and Technology publications, and Office of Management and 
Budget guidance.
    (4) The clearinghouse must provide quarterly reports to the Wireless 
Telecommunications Bureau that detail the status of reimbursement funds 
available, the payments issued, the amounts collected from licensees, 
and any information filed by incumbents. The reports must account for 
all funds spent, including the clearinghouse's own expenses. The report 
shall include descriptions of any disputes and the manner in which they 
were resolved.
    (b) Non-Federal secondary radiolocation licensees in the 3.3-3.55 
GHz band that seek reimbursement of their expenses for relocating 
operations authorized under their licenses and existing as of February 
22, 2019, must submit invoices or other appropriate documentation of 
such expenses to the clearinghouse no later than a date to be specified 
by public notice.
    (c) Expenses must be reasonably related to the relocation from the 
3.3-3.55 GHz band to the 2.9-3.0 GHz band, may be future expenses or 
expenses already incurred--including the clearinghouse's costs, and no 
expenses for other purposes will be subject to reimbursement. Ineligible 
expenses include, but are not limited to, those related to upgrades or 
improvements. The clearinghouse shall have the authority to determine 
whether particular expenses are eligible for reimbursement.
    (d) The Wireless Telecommunications Bureau is responsible for 
resolving any disputes arising from decisions by the

[[Page 426]]

clearinghouse and shall specify by public notice when the 
clearinghouse's responsibilities have terminated.



Sec.  27.1606  Aggregation of 3450-3550 MHz band licenses.

    (a) 3.45 GHz Service licensees may aggregate up to 40 megahertz of 
3450-3550 MHz band licenses across both license categories in any 
service area at any given time for four years after the close of the 
auction. After four years post-auction, no such aggregation limit on 
3450-3550 MHz licenses shall apply.
    (b) The criteria in Sec.  20.22(b) of this chapter will apply in 
order to attribute partial ownership and other interests for the purpose 
of applying the aggregation limit in paragraph (a) of this section.



Sec.  27.1607  Information sharing for time division duplex 
synchronization.

    (a) 3.45 GHz Service licensees must provide information to 
requesting Citizens Broadband Radio Service (part 96 of this chapter) 
operators to enable time division duplex (TDD) synchronization. 
Negotiations over the information must be conducted in good faith, with 
the goal of enabling synchronization between the relevant systems.
    (1) A Citizens Broadband Radio Service operator, whether a Priority 
Access Licensee or a General Authorized Access user (Sec.  96.1(b) of 
this chapter), may request information from a 3.45 GHz Service licensee 
to enable cross-service TDD synchronization if it provides service, or 
intends to provide service, in the same or adjacent geographic area as a 
3.45 GHz Service licensee.
    (2) Upon request by an eligible Citizens Broadband Radio Service 
operator, the 3.45 GHz Service licensee must provide sufficient 
technical information to allow the Citizens Broadband Radio Service 
operator to synchronize its system with the 3.45 GHz band system. The 
3.45 GHz Service licensee must keep this information current if its 
network operations change.
    (b) 3.45 GHz Service licensees are under no obligation to make any 
changes to their operations or proposed operations to enable TDD 
synchronization.

are not required and will not be accepted, except where required for 
environmental assessments, in accordance with Sec. Sec.  1.1301 through 
1.1319 of this chapter.



Sec.  30.102  Transition of existing local multipoint distribution service
and 39 GHz licenses.

    Local Multipoint Distribution Service licenses in the 27.5--28.35 
GHz band issued on a Basic Trading Area basis shall be disaggregated 
into county-based licenses and 39 GHz licenses issued on an Economic 
Area basis shall be disaggregated into Partial Economic Area-based 
licenses on December 14, 2016. For each county in the Basic Trading Area 
or Partial Economic Area in the Economic Area which is part of the 
original license, the licensee shall receive a separate license. If 
there is a co-channel Rectangular Service Area licensee within the 
service area of a 39 GHz Economic Area licensee, the disaggregated 
license shall not authorize operation with the service area of the 
Rectangular Service Area license.



Sec.  30.103  License term.

    Initial authorizations will have a term not to exceed ten years from 
the date of initial issuance or renewal.



Sec.  30.104  Performance requirements.

    (a) Upper Microwave Flexible Use Service licensees must make a 
buildout showing as part of their renewal applications. Licensees 
relying on mobile or point-to-multipoint service must show that they are 
providing reliable signal coverage and service to at least 40 percent of 
the population within the service area of the licensee, and that they 
are using facilities to provide service in that area either to customers 
or for internal use. Licensees relying on point-to-point service must 
demonstrate that they have four links operating and providing service, 
either to customers or for internal use, if the population within the 
license area is equal to or less than 268,000. If the population within 
the license area is greater than 268,000, a licensee relying on point-
to-point service must demonstrate it has at least one link in operation 
and is providing service for each 67,000 population within the license 
area. In order to be eligible to be counted under the point-to-point 
buildout standard, a point-to-point link must operate with a transmit 
power greater than +43 dBm.
    (b) In the alternative, a licensee may make its buildout showing on 
the basis of geographic area coverage. To satisfy the requirements of 
using this metric, licensees relying on mobile or point-to-multipoint 
service must show that they are providing reliable signal coverage and 
service to at least 25% of the geographic area of the license. The 
geographic area of the license shall be determined by the total land 
area of the county or counties covered by the license. Licensees relying 
on fixed point-to-point links or other, low-power point-to-point 
connections must show that they have deployed at least one transmitter 
or receiver in at least 25% of the census tracts within the license

[[Page 430]]

area. All equipment relied upon in the showing, whatever type of service 
or connection it provides, must be operational and providing service, 
either to customers or for internal use, as of the date of the filing.
    (c) Showings that rely on a combination of multiple types of service 
will be evaluated on a case-by-case basis. Licensees may not combine 
population-based showings with geographic area-based showings.
    (d) If a licensee in this service is also a Fixed-Satellite Service 
licensee and uses the spectrum covered under its UMFUS license in 
connection with a satellite earth station, it can demonstrate compliance 
with the requirements of this section by demonstrating that the earth 
station in question is in service, operational, and using the spectrum 
associated with the license. This provision can only be used to 
demonstrate compliance for the county in which the earth station is 
located.
    (e) Failure to meet this requirement will result in automatic 
cancellation of the license. In bands licensed on a Partial Economic 
Area basis, licensees will have the option of partitioning a license on 
a county basis in order to reduce the population or land area within the 
license area to a level where the licensee's buildout would meet one of 
the applicable performance metrics.
    (f) Existing 24 GHz, 28 GHz and 39 GHz licensees shall be required 
to make a showing pursuant to this section by June 1, 2024.

34492, July 20, 2018]



Sec.  30.105  Geographic partitioning and spectrum disaggregation.

    (a) Parties seeking approval for partitioning and disaggregation 
shall request from the Commission an authorization for partial 
assignment of a license pursuant to Sec.  1.948 of this chapter. Upper 
Microwave Flexible Use Service licensees may apply to partition their 
licensed geographic service area or disaggregate their licensed spectrum 
at any time following the grant of their licenses.
    (b) Technical standards--(1) Partitioning. In the case of 
partitioning, applicants and licensees must file FCC Form 603 pursuant 
to Sec.  1.948 of this chapter and list the partitioned service area on 
a schedule to the application. The geographic coordinates must be 
specified in degrees, minutes, and seconds to the nearest second of 
latitude and longitude and must be based upon the 1983 North American 
Datum (NAD83).
    (2) Spectrum may be disaggregated in any amount.
    (3) The Commission will consider requests for partial assignment of 
licenses that propose combinations of partitioning and disaggregation.
    (4) For purposes of partitioning and disaggregation, part 30 systems 
must be designed so as not to exceed the signal level specified for the 
particular spectrum block in Sec.  30.204 at the licensee's service area 
boundary, unless the affected adjacent service area licensees have 
agreed to a different signal level.
    (c) License term. The license term for a partitioned license area 
and for disaggregated spectrum shall be the remainder of the original 
licensee's license term as provided for in Sec.  30.103.

Sec.  30.202  Power limits.

    (a) For fixed and base stations operating in connection with mobile 
systems, the average power of the sum of all antenna elements is limited 
to an equivalent isotopically radiated power (EIRP) density of +75dBm/
100 MHz. For channel bandwidths less than 100 megahertz the EIRP must be 
reduced proportionally and linearly based on the bandwidth relative to 
100 megahertz.
    (b) For mobile stations, the average power of the sum of all antenna 
elements is limited to a maximum EIRP of +43 dBm.
    (c) For transportable stations, as defined in Sec.  30.2, the 
average power of the sum of all antenna elements is limited to a maximum 
EIRP of +55 dBm.
    (d) For fixed point-to-point and point-to-multipoint limits see 
Sec.  30.405.



Sec.  30.203  Emission limits.

    (a) The conductive power or the total radiated power of any emission 
outside a licensee's frequency block shall be -13 dBm/MHz or lower. 
However, in the bands immediately outside and adjacent to the licensee's 
frequency block, having a bandwidth equal to 10 percent of the channel 
bandwidth, the conductive power or the total radiated power of any 
emission shall be -5 dBm/MHz or lower.
    (b)(1) Compliance with this provision is based on the use of 
measurement instrumentation employing a resolution bandwidth of 1 
megahertz or greater.
    (2) When measuring the emission limits, the nominal carrier 
frequency shall be adjusted as close to the licensee's frequency block 
edges as the design permits.
    (3) The measurements of emission power can be expressed in peak or 
average values.
    (c) For fixed point-to-point and point-to-multipoint limits see 
Sec.  30.404.



Sec.  30.204  Field strength limits.

    (a) Base/mobile operations: The predicted or measured Power Flux 
Density (PFD) from any Base Station operating in the 27.5-28.35 GHz 
band, 37-38.6 GHz band, and 38.6-40 GHz bands at any location on the 
geographical border of a licensee's service area shall not exceed -
76dBm/m\2\/MHz (measured at 1.5 meters above ground) unless the adjacent 
affected service area licensee(s) agree(s) to a different PFD.
    (b) Fixed point-to-point operations. (1) Prior to operating a fixed 
point-to-point transmitting facility in the 27,500-28,350 MHz band where 
the facilities are located within 20 kilometers of the boundary of the 
licensees authorized market area, the licensee must complete frequency 
coordination in accordance with the procedures specified in Sec.  
101.103(d)(2) of this chapter with respect to neighboring licensees that 
may be affected by its operations.
    (2) Prior to operating a fixed point-to-point transmitting facility 
in the 37,000-40,000 MHz band where the facilities are located within 16 
kilometers of the boundary of the licensees authorized market area, the 
licensee must complete frequency coordination in accordance with the 
procedures specified in Sec.  101.103(d)(2) of this chapter with respect 
to neighboring licensees that may be affected by its operations.



Sec.  30.205  Federal coordination requirements.

    (a) Licensees in the 37-38 GHz band located within the zones defined 
by the coordinates in the tables below must coordinate their operations 
with Federal Space Research Service (space to Earth) users of the band 
via the National Telecommunications and Information Administration 
(NTIA). All licensees operating within the zone defined by the 60 dBm/
100 MHz EIRP coordinates in the tables below must coordinate all 
operations. Licensees operating within the area between the zones 
defined by the 60 dBm and 75 dBm/100 MHz EIRP coordinates in the tables 
below must coordinate all operations if their base station EIRP is 
greater than 60 dBm/100 MHz or if their antenna height exceeds 100 
meters above ground level. Licensees operating outside the zones defined

38,600 to 40,000........................................            0.03
------------------------------------------------------------------------



Sec.  30.403  Bandwidth.

    (a) Stations under this subpart will be authorized any type of 
emission, method of modulation, and transmission characteristic, 
consistent with efficient use of the spectrum and good engineering 
practice.
    (b) The maximum bandwidth authorized per frequency to stations under 
this subpart is set out in the table that follows.

------------------------------------------------------------------------
                                                              Maximum
                  Frequency band (MHz)                      authorized
                                                             bandwidth
------------------------------------------------------------------------
27,500 to 28,350........................................        850 MHz.
38,600 to 40,000........................................     200 MHz.\1\
------------------------------------------------------------------------
\1\ For channel block assignments in the 38,600-40,000 MHz bands when
  adjacent channels are aggregated, equipment is permitted to operate
  over the full channel block aggregation without restriction.



Sec.  30.404  Emission limits.

    (a) The mean power of emissions must be attenuated below the mean 
output power of the transmitter in accordance with the following 
schedule:

[[Page 435]]

    (1) When using transmissions other than those employing digital 
modulation techniques:
    (i) On any frequency removed from the assigned frequency by more 
than 50 percent up to and including 100 percent of the authorized 
bandwidth: At least 25 decibels;
    (ii) On any frequency removed from the assigned frequency by more 
than 100 percent up to and including 250 percent of the authorized 
bandwidth: At least 35 decibels;
    (iii) On any frequency removed from the assigned frequency by more 
than 250 percent of the authorized bandwidth: At least 43 + 10 
Log10 (mean output power in watts) decibels, or 80 decibels, 
whichever is the lesser attenuation.
    (2) When using transmissions employing digital modulation techniques 
in situations not covered in this section:
    (i) In any 1 MHz band, the center frequency of which is removed from 
the assigned frequency by more than 50 percent up to and including 250 
percent of the authorized bandwidth: As specified by the following 
equation but in no event less than 11 decibels:

A = 11 + 0.4(P-50) + 10 Log10 B. (Attenuation greater than 56 
decibels or to an absolute power of less than -13 dBm/1MHz is not 
required.)
    (ii) In any 1 MHz band, the center frequency of which is removed 
from the assigned frequency by more than 250 percent of the authorized 
bandwidth: At least 43 + 10 Log10 (the mean output power in 
watts) decibels, or 80 decibels, whichever is the lesser attenuation. 
The authorized bandwidth includes the nominal radio frequency bandwidth 
of an individual transmitter/modulator in block-assigned bands. 
Equipment licensed prior to April 1, 2005 shall only be required to meet 
this standard in any 4 kHz band.
    (iii) The emission mask in paragraph (a)(2)(i) of this section 
applies only to the band edge of each block of spectrum, but not to 
subchannels established by licensees. The value of P in the equation is 
the percentage removed from the carrier frequency and assumes that the 
carrier frequency is the center of the actual bandwidth used. The 
emission mask can be satisfied by locating a carrier of the subchannel 
sufficiently far from the channel edges so that the emission levels of 
the mask are satisfied. The emission mask shall use a value B 
(bandwidth) of 40 MHz, for all cases even in the case where a narrower 
subchannel is used (for instance the actual bandwidth is 10 MHz) and the 
mean output power used in the calculation is the sum of the output power 
of a fully populated channel. For block assigned channels, the out-of-
band emission limits apply only outside the assigned band of operation 
and not within the band.
    (b) [Reserved]



Sec.  30.405  Transmitter power limitations.

    On any authorized frequency, the average power delivered to an 
antenna in this service must be the minimum amount of power necessary to 
carry out the communications desired. Application of this principle 
includes, but is not to be limited to, requiring a licensee who replaces 
one or more of its antennas with larger antennas to reduce its antenna 
input power by an amount appropriate to compensate for the increased 
primary lobe gain of the replacement antenna(s). In no event shall the 
average equivalent isotropically radiated power (EIRP), as referenced to 
an isotropic radiator, exceed the following:

                         Maximum Allowable EIRP
------------------------------------------------------------------------
                  Frequency band (MHz)                      Fixed (dBW)
------------------------------------------------------------------------
27,500-28,350\1\........................................            + 55
38,600-40,000...........................................            + 55
------------------------------------------------------------------------
\1\ For Point-to-multipoint user stations authorized in these bands, the
  EIRP shall not exceed 55 dBw or 42 dBw/MHz.



Sec.  30.406  Directional antennas.

    (a) Unless otherwise authorized upon specific request by the 
applicant, each station authorized under the rules of this subpart must 
employ a directional antenna adjusted with the center of the major lobe 
of radiation in the horizontal plane directed toward the receiving 
station with which it communicates: provided, however, where a station 
communicates with more than one point, a multi- or omni-directional 
antenna may be authorized if necessary.
    (b) Fixed stations (other than temporary fixed stations) must employ 
transmitting and receiving antennas

[[Page 436]]

(excluding second receiving antennas for operations such as space 
diversity) meeting the appropriate performance Standard A indicated in 
the table to this section, except that in areas not subject to frequency 
congestion, antennas meeting performance Standard B may be used. For 
frequencies with a Standard B1 and a Standard B2, in order to comply 
with Standard B an antenna must fully meet either Standard B1 or 
Standard B2. Licensees shall comply with the antenna standards table 
shown in this paragraph in the following manner:
    (1) With either the maximum beamwidth to 3 dB points requirement or 
with the minimum antenna gain requirement; and
    (2) With the minimum radiation suppression to angle requirement.

\1\ If a licensee chooses to show compliance using maximum beamwidth to 3 dB points, the beamwidth limit shall apply in both the azimuth and the elevation planes.
\2\ Stations authorized to operate in the 38,600-40,000 MHz band may use antennas other than those meeting the Category A standard. However, the Commission may require the use of higher
  performance antennas where interference problems can be resolved by the use of such antennas.

                            Subpart A_Preface



Sec.  32.1  Background.

    The revised Uniform System of Accounts (USOA) is a historical 
financial accounting system which reports the results of operational and 
financial events in a manner which enables both management and 
regulators to assess these results within a specified accounting period. 
The USOA also provides the financial community and others with financial 
performance results. In order for an accounting system to fulfill these 
purposes, it must exhibit consistency and stability in financial 
reporting (including the results published for regulatory purposes). 
Accordingly, the USOA has been designed to reflect stable, recurring 
financial data based to the extent regulatory considerations permit upon 
the consistency of the well-established body of accounting theories and 
principles commonly referred to as generally accepted accounting 
principles (GAAP). The rules of this part, and any other rules or orders 
that are derivative of or dependent on the rules in this part, do not 
apply to price cap companies, and rate-of-return telephone companies 
offering business data services pursuant to Sec.  61.50 of this chapter, 
that have opted-out of USOA requirements pursuant to the conditions 
specified by the Commission in Sec.  32.11(g).

[83 FR 67121, Dec. 28, 2018]



Sec.  32.2  Basis of the accounts.

    (a) The financial accounts of a company are used to record, in 
monetary terms, the basic transactions which occur. Certain natural 
groupings of these transactions are called (in different contexts) 
transaction cycles, business processes, functions or activities. The 
concept, however, is the same in each case; i.e., the natural groupings 
represent what happens within the company on a consistent and continuing 
basis. This repetitive nature of the natural groupings, over long 
periods of time, lends an element of stability to the financial account 
structure.
    (b) Within the telecommunications industry companies, certain 
recurring functions (natural groupings) do take place in the course of 
providing products and services to customers. These accounts reflect, to 
the extent feasible, those functions. For example, the primary bases of 
the accounts containing the investment in telecommunications plant are 
the functions performed by the assets. In addition, because of the 
anticipated effects of future innovations, the telecommunications plant 
accounts are intended to permit technological distinctions. Similarly, 
the primary bases of plant operations, customer operations and corporate 
operations expense accounts are the functions performed by individuals. 
The revenue accounts, on the other hand, reflect a market perspective of 
natural groupings based primarily upon the products and services 
purchased by customers.
    (c) In the course of developing the bases for this account 
structure, several other alternatives were explored. It was, for 
example, determined that, because of the variety and continual changing 
of various cost allocation mechanisms, the financial accounts of a 
company should not reflect an a priori allocation of revenues, 
investments or expenses to products or services, jurisdictions or 
organizational structures. (Note also Sec.  32.14 (c) and (d) of subpart 
B.) It was also determined that costs (in the case of assets) should not 
be recorded based solely upon physical attributes such as location, 
description or size.
    (d) Care has been taken in this account structure to avoid confusing 
a function with an organizational responsibility, particularly as it 
relates

[[Page 441]]

to the expense accounts. Whereas in the past, specific organizations may 
have performed specific functions, the future environment with its 
increasing mechanization and other changes will result in entirely new 
or restructured organizations. Thus, any relationships drawn between 
organizations and accounts would become increasingly meaningless with 
the passage of time.
    (e) These accounts, then, are intended to reflect a functional and 
technological view of the telecommunications industry. This view will 
provide a stable and consistent foundation for the recording of 
financial data.
    (f) The financial data contained in the accounts, together with the 
detailed information contained in the underlying financial and other 
subsidiary records required by this Commission, will provide the 
information necessary to support separations, cost of service and 
management reporting requirements. The basic account structure has been 
designed to remain stable as reporting requirements change.



Sec.  32.3  [Reserved]



Sec.  32.4  Communications Act.

    Attention is directed to the following extract from section 220 of 
the Communications Act of 1934, 47 U.S.C. 220 (1984):

    (e) Any person who shall willfully make any false entry in the 
accounts of any book of accounts or in any record or memoranda kept by 
any such carrier, or who shall willfully destroy, mutilate, alter, or by 
any other means or device falsify any such account, record, or 
memoranda, or who shall willfully neglect or fail to make full, true, 
and correct entries in such accounts, records, or memoranda of all facts 
and transactions appertaining to the business of the carrier, shall be 
deemed guilty of a misdemeanor, and shall be subject, upon conviction, 
to a fine of not less than $1,000 nor more than $5,000 or imprisonment 
for a term of not less than one year nor more than three years, or both 
such fine and imprisonment: Provided, that the Commission may in its 
discretion issue orders specifying such operating, accounting or 
financial papers, records, books, blanks, or documents which may, after 
a reasonable time, be destroyed, and prescribing the length of time such 
books, papers, or documents shall be preserved.


For regulations governing the periods for which records are to be 
retained, see part 42, Preservation of Records of Communications Common 
Carriers, of this chapter which relates to preservation of records.



                     Subpart B_General Instructions



Sec.  32.11  Companies subject to this part.

    (a) This part applies to every incumbent local exchange carrier, as 
defined in section 251(h) of the Communications Act, and any other 
carrier that the Commission designates by order. This part refers to 
such carriers as ``companies'' or ``Class B companies.'' Incumbent local 
exchange carriers' successor or assign companies, as defined in section 
251(h)(1)(B)(ii) of the Communications Act, that are found to be non-
dominant by the Commission, will not be subject to this Uniform System 
of Accounts.
    (b)--(f) [Reserved]
    (g) Notwithstanding paragraph (a) of this section, a price cap 
company, or a rate-of-return telephone company offering business data 
services pursuant to Sec.  61.50 of this chapter, that elects to 
calculate its pole attachment rates pursuant to Sec.  1.1406(e) of this 
chapter will not be subject to this Uniform System of Accounts.

FR 20840, May 4, 2017; 83 FR 67121, Dec. 28, 2018]



Sec.  32.12  Records.

    (a) The company's financial records shall be kept in accordance with 
generally accepted accounting principles to the extent permitted by this 
system of accounts.
    (b) The company's financial records shall be kept with sufficient 
particularity to show fully the facts pertaining to all entries in these 
accounts. The detail records shall be filed in such manner as to be 
readily accessible for examination by representatives of this 
Commission.
    (c) The Commission shall require a company to maintain financial and 
other subsidiary records in such a manner that specific information, of 
a type not warranting disclosure as an account or subaccount, will be 
readily available. When this occurs, or where

[[Page 442]]

the full information is not otherwise recorded in the general books, the 
subsidiary records shall be maintained in sufficient detail to 
facilitate the reporting of the required specific information. The 
subsidiary records, in which the full details are shown, shall be 
sufficiently referenced to permit ready identification and examination 
by representatives of this Commission.



Sec.  32.13  Accounts--general.

    (a) As a general rule, all accounts kept by reporting companies 
shall conform in numbers and titles to those prescribed herein. However, 
reporting companies may use different numbers for internal purposes when 
separate accounts (or subaccounts) maintained are consistent with the 
title and content of accounts and subaccounts prescribed in this system.
    (1) A company may subdivide any of the accounts prescribed. The 
titles of all such subaccounts shall refer by number or title to the 
controlling account.
    (2) A company may establish temporary or experimental accounts 
without prior notice to the Commission.
    (b) Exercise of the preceding options shall be allowed only if the 
integrity of the prescribed accounts is not impaired.
    (c) As of the date a company becomes subject to the system of 
accounts, the company is authorized to make any such subdivisions, 
reclassifications or consolidations of existing balances as are 
necessary to meet the requirements of this system of accounts.
    (d) Nothing contained in this part shall prohibit or excuse any 
company, receiver, or operating trustee of any carrier from subdividing 
the accounts hereby prescribed for the purpose of:
    (1) Complying with the requirements of the state commission(s) 
having jurisdiction; or
    (2) Securing the information required in the prescribed reports to 
such commission(s).
    (e) Where the use of subsidiary records is considered necessary in 
order to secure the information required in reports to any state 
commission, the company shall incorporate the following controls into 
their accounting system with respect to such subsidiary records:
    (1) Subsidiary records shall be reconciled to the company's general 
ledger or books of original entry, as appropriate.
    (2) The company shall adequately document the accounting procedures 
related to subsidiary records.
    (3) The subsidiary records shall be maintained at an adequate level 
of detail to satisfy state regulators.

FR 5679, Feb. 6, 2002]



Sec.  32.14  Regulated accounts.

    (a) In the context of this part, the regulated accounts shall be 
interpreted to include the investments, revenues and expenses associated 
with those telecommunications products and services to which the tariff 
filing requirements contained in Title II of the Communications Act of 
1934, as amended, are applied, except as may be otherwise provided by 
the Commission. Regulated telecommunications products and services are 
thereby fully subject to the accounting requirements as specified in 
Title II of the Communications Act of 1934, as amended, and as detailed 
in subparts A through F of this part of the Commission's Rules and 
Regulations.
    (b) In addition to those amounts considered to be regulated by the 
provisions of paragraph (a) of this section, those telecommunications 
products and services to which the tariff filing requirements of the 
several state jurisdictions are applied shall be accounted for as 
regulated, except where such treatment is proscribed or otherwise 
excluded from the requirements pertaining to regulated 
telecommunications products and services by this Commission.
    (c) In the application of detailed accounting requirements contained 
in this part, when a regulated activity involves the common or joint use 
of assets and resources in the provision of regulated and nonregulated 
products and services, companies shall account for these activities 
within the accounts prescribed in this system for telephone company 
operations. Assets and expenses shall be subdivided in subsidiary

[[Page 443]]

records among amounts solely assignable to nonregulated activities, 
amounts solely assignable to regulated activities, and amounts related 
to assets used and expenses incurred jointly or in common, which will be 
allocated between regulated and nonregulated activities. Companies shall 
submit reports identifying regulated and nonregulated amounts in the 
manner and at the times prescribed by this Commission. Nonregulated 
revenue items not qualifying for incidental treatment, as provided in 
Sec.  32.4999(l), shall be recorded in Account 5280, Nonregulated 
operating revenue.
    (d) Other income items which are incidental to the provision of 
regulated products and services shall be accounted for as regulated 
activities.
    (e) All costs and revenues related to the offering of regulated 
products and services which result from arrangements for joint 
participation or apportionment between two or more telephone companies 
(e.g., joint operating agreements, settlement agreements, cost-pooling 
agreements) shall be recorded within the detailed accounts. Under joint 
operating agreements, the creditor will initially charge the entire 
expenses to the appropriate primary accounts. The proportion of such 
expenses borne by the debtor shall be credited by the creditor and 
charged by the debtor to the account initially charged. Any allowances 
for return on property used will be accounted for as provided in Account 
5200, Miscellaneous revenue.
    (f) All items of nonregulated revenue, investment and expense that 
are not properly includible in the detailed, regulated accounts 
prescribed in subparts A through F of this part, as determined by 
paragraphs (a) through (e) of this section shall be accounted for and 
included in reports to this Commission as specified in Sec.  32.23 of 
this subpart.

[51 FR 43499, Dec. 2, 1986, as amended at 52 FR 6560, Mar. 4, 1987; 53

Sec.  32.15  [Reserved]



Sec.  32.16  Changes in accounting standards.

    (a) The company's records and accounts shall be adjusted to apply 
new accounting standards prescribed by the Financial Accounting 
Standards Board or successor authoritative accounting standard-setting 
groups, in a manner consistent with generally accepted accounting 
principles. The change in an accounting standard will automatically take 
effect 90 days after the company informs this Commission of its 
intention to follow the new standard, unless the Commission notifies the 
company to the contrary. Any change adopted shall be disclosed in annual 
reports required by Sec.  43.21(f) of this chapter in the year of 
adoption.
    (b) The changes in accounting standards which this Commission 
approves will not necessarily be binding on the ratemaking practices of 
the various state commissions.

Sec.  32.17  Interpretation of accounts.

    To the end that uniform accounting shall be maintained within the 
prescribed system, questions involving significant matters which are not 
clearly provided for shall be submitted to the Chief, Wireline 
Competition Bureau, for explanation, interpretation, or resolution. 
Questions and answers thereto with respect to this system of accounts 
will be maintained by the Wireline Competition Bureau.

[67 FR 13225, Mar. 21, 2002]



Sec.  32.18  Waivers.

    A waiver from any provision of this system of accounts shall be made 
by the Federal Communications Commission upon its own initiative or upon 
the submission of written request therefor from any telecommunications 
company, or group of telecommunications companies, provided that such a 
waiver is in the public interest and each request for waiver expressly 
demonstrates that: existing peculiarities or unusual circumstances 
warrant a departure from a prescribed procedure or technique; a 
specifically defined alternative procedure or technique will result in a 
substantially equivalent or more accurate portrayal of operating results 
or financial condition, consistent with the principles embodied in

[[Page 444]]

the provisions of this system of accounts; and the application of such 
alternative procedure will maintain or improve uniformity in substantive 
results as among telecommunications companies.



Sec.  32.19  Address for reports and correspondence.

    Reports, statements, and correspondence submitted to the Federal 
Communications Commission in accordance with or relating to instructions 
and requirements contained herein shall be addressed to the Wireless 
Competition Bureau, Federal Communications Commission, Washington, DC 
20554.

[51 FR 43499, Dec. 2, 1986, as amended at 67 FR 13225, Mar. 21, 2002]



Sec.  32.20  Numbering convention.

    (a) The number ``32'' (appearing to the left of the first decimal 
point) indicates the part number.
    (b) The numbers immediately following to the right of the decimal 
point indicate, respectively, the section or account. All Part 32 
Account numbers contain 4 digits to-the-right-of the decimal point.
    (c) Cross references to accounts are made by citing the account 
numbers to the right of the decimal point; e.g., Account 2232 rather 
than the corresponding complete part 32 reference number 32.2232.



Sec.  32.21  Sequence of accounts.

    The order in which the accounts are presented in this system of 
accounts is not to be considered as necessarily indicative of the order 
in which they will be scheduled at all times in reports to this 
Commission.



Sec.  32.22  Comprehensive interperiod tax allocation.

    (a) Companies shall apply interperiod tax allocation (tax 
normalization) to all book/tax temporary differences which would be 
considered material for published financial report purposes. 
Furthermore, companies shall also apply interperiod tax allocation if 
any item or group of similar items when aggregated would yield debit or 
credit entries which exceed or would exceed 5 percent of the gross 
deferred income tax expense debits or credits during any calendar year 
over the life of the temporary difference. The tax effects of book/tax 
temporary differences shall be normalized and the deferrals shall be 
included in the following accounts:

4100, Net Current Deferred Operating Income Taxes;
4110, Net Current Deferred Nonoperating Income Taxes;
4340, Net Noncurrent Deferred Operating Income Taxes;
4350, Net Noncurrent Deferred Nonoperating Income Taxes.

    In lieu of the accounting prescribed herein, any company shall treat 
the increase or reduction in current income taxes payable resulting from 
the use of flow through accounting in prior years as an increase or 
reduction in current tax expense.
    (b) Supporting documentation shall be maintained so as to separately 
identify the amount of deferred taxes which arise from the use of an 
accelerated method of depreciation.
    (c) Subsidiary records shall be used to reduce the deferred tax 
assets contained in the accounts specified in paragraph (a) of this 
section when it is likely that some portion or all of the deferred tax 
asset will not be realized. The amount recorded in the subsidiary record 
should be sufficient to reduce the deferred tax asset to the amount that 
is likely to be realized.
    (d) The records supporting the activity in the deferred income tax 
accounts shall be maintained in sufficient detail to identify the nature 
of the specific temporary differences giving rise to both the debits and 
credits to the individual accounts.
    (e) Any company that uses accelerated depreciation (or recognizes 
taxable income or losses upon the retirement of property) for income tax 
purposes shall normalize the tax differentials occasioned thereby as 
indicated in paragraphs (e)(1) and (e)(2) of this section.
    (1) With respect to the retirement of property the book/tax 
difference between (i) the recognition of proceeds as income and the 
accrual for salvage value and (ii) the book and tax capital recovery, 
shall be normalized.
    (2) Records shall be maintained so as to show the deferred tax 
amounts by vintage year separately for each class

[[Page 445]]

or subclass of eligible depreciable telephone plant for which an 
accelerated method of depreciation has been used for income tax 
purposes. When property is transferred to nonregulated activities, the 
associated deferred income taxes and unamortized investment tax credits 
shall also be identified and transferred to the appropriate nonregulated 
accounts.
    (f) The tax differentials to be normalized as specified in this 
section shall also encompass the additional effect of state and local 
income tax changes on Federal income taxes produced by the provision for 
deferred state and local income taxes for book/tax temporary differences 
related to such income taxes.
    (g) Companies that receive the tax benefits from the filing of a 
consolidated income tax return by the parent company, (pursuant to 
closing agreements with the Internal Revenue Service, effective January 
1, 1966) representing the deferred income taxes from the elimination of 
intercompany profits for income tax purposes on sales of regulated 
equipment, may credit such deferred taxes directly to the plant account 
which contains such intercompany profit rather than crediting such

Sec.  32.23  Nonregulated activities.

    (a) This section describes the accounting treatment of activities 
classified for accounting purposes as ``nonregulated.'' Preemptively 
deregulated activities and activities (other than incidental activities) 
never subject to regulation will be classified for accounting purposes 
as ``nonregulated.'' Activities that qualify for incidental treatment 
under the policies of this Commission will be classified for accounting 
purposes as regulated activities. Activities that have been deregulated 
by a state will be classified for accounting purposes as regulated 
activities. Activities that have been deregulated at the interstate 
level, but not preemptively deregulated, will be classified for 
accounting purposes as regulated activities until such time as this 
Commission decides otherwise. The treatment of nonregulated activities 
shall differ depending on the extent of the common or joint use of 
assets and resources in the provision of both regulated and nonregulated 
products and services.
    (b) When a nonregulated activity does not involve the joint or 
common use of assets and resources in the provision of both regulated 
and nonregulated products and services, carriers shall account for these 
activities on a separate set of books consistent with instructions set 
forth in Sec. Sec.  32.1406 and 32.7990. Transfers of assets, and sales 
of products and services between the regulated activity and a 
nonregulated activity for which a separate set of books is maintained, 
shall be accounted for in accordance with the rules presented in Sec.  
32.27, Transactions with Affiliates. In the separate set of books, 
carriers may establish whatever detail they deem appropriate beyond what 
is necessary to provide this Commission with the information required in 
Sec. Sec.  32.1406 and 32.7990.
    (c) When a nonregulated activity does involve the joint or common 
use of assets and resources in the provision of regulated and 
nonregulated products and services, carriers shall account for these 
activities within accounts prescribed in this system for telephone 
company operations. Assets and expenses shall be subdivided in 
subsidiary records among amounts solely assignable to nonregulated 
activities, amounts solely assignable to regulated activities, and 
amounts related to assets and expenses incurred jointly or in common, 
which will be allocated between regulated and nonregulated activities. 
Carriers shall submit reports identifying regulated and nonregulated 
amounts in the manner and at the times prescribed by this Commission. 
Nonregulated revenue items not qualifying for incidental treatment as 
provided in Sec.  32.4999(l) of this part, shall be recorded in separate 
subsidiary record

categories of Account 5280, Nonregulated operating revenue. Amounts 
assigned or allocated to regulated products or services shall be subject 
to part 36 of this chapter.

Sec.  32.24  Compensated absences.

    (a) Companies shall record a liability and charge the appropriate 
expense accounts for compensated absences (vacations, sick leave, etc.) 
in the year in which these benefits are earned by employees.
    (b) With respect to the liability that exists for compensated 
absences which is not yet recorded on the books as of the effective date 
of this part, the liability shall be recorded in Account 4130. Other 
current liabilities, with a corresponding entry to Account 1438, 
Deferred maintenance, retirements and other deferred charges. This 
deferred charge shall be amortized on a straight-line basis over a 
period of ten years.
    (c) Records shall be maintained so as to show that no more than ten 
percent of the deferred charge is being amortized each year.

Sec.  32.25  Unusual items and contingent liabilities.

    Extraordinary items, prior period adjustments, and contingent 
liabilities may be recorded in the company's books of account without 
prior Commission approval.

[65 FR 16334, Mar. 28, 2000]



Sec.  32.26  Materiality.

    (a) Except as provided in paragraph (b) of this section, companies 
may abide by the materiality standards of GAAP when implementing this 
system of accounts.
    (b) For companies that receive High-Cost Loop Support, or Connect 
America Fund Broadband Loop Support, materiality shall be determined 
consistent with the general materiality guidelines promulgated by the 
Auditing Standards Board.

[82 FR 20840, May 4, 2017]



Sec.  32.27  Transactions with affiliates.

    (a) Unless otherwise approved by the Chief, Wireline Competition 
Bureau, transactions with affiliates involving asset transfers into or 
out of the regulated accounts shall be recorded by the carrier in its 
regulated accounts as provided in paragraphs (b) through (f) of this 
section.
    (b) Assets sold or transferred between a carrier and its affiliate 
pursuant to a tariff, including a tariff filed with a state commission, 
shall be recorded in the appropriate revenue accounts at the tariffed 
rate. Non-tariffed assets sold or transferred between a carrier and its 
affiliate that qualify for prevailing price valuation, as defined in 
paragraph (d) of this section, shall be recorded at the prevailing 
price. For all other assets sold by or transferred from a carrier to its 
affiliate, the assets shall be recorded at no less than the higher of 
fair market value and net book cost. For all other assets sold by or 
transferred to a carrier from its affiliate, the assets shall be 
recorded at no more than the lower of fair market value and net book 
cost.
    (1) Floor. When assets are sold by or transferred from a carrier to 
an affiliate, the higher of fair market value and net book cost 
establishes a floor, below which the transaction cannot be recorded. 
Carriers may record the transaction at an amount equal to or greater 
than the floor, so long as that action complies with the Communications 
Act of 1934, as amended, Commission rules and orders, and is not 
otherwise anti-competitive.
    (2) Ceiling. When assets are purchased from or transferred from an 
affiliate to a carrier, the lower of fair market value and net book cost 
establishes a ceiling, above which the transaction cannot be recorded. 
Carriers may record the transaction at an amount equal to or less than 
the ceiling, so long as that action complies with the Communications Act 
of 1934, as amended, Commission rules and orders, and is not otherwise 
anti-competitive.
    (3) Threshold. For purposes of this section carriers are required to 
make a good faith determination of fair market value for an asset when 
the total aggregate annual value of the asset(s)

[[Page 447]]

reaches or exceeds $500,000, per affiliate. When a carrier reaches or 
exceeds the $500,000 threshold for a particular asset for the first 
time, the carrier must perform the market valuation and value the 
transaction on a going-forward basis in accordance with the affiliate 
transactions rules on a going-forward basis. When the total aggregate 
annual value of the asset(s) does not reach or exceed $500,000, the 
asset(s) shall be recorded at net book cost.
    (c) Services provided between a carrier and its affiliate pursuant 
to a tariff, including a tariff filed with a state commission, shall be 
recorded in the appropriate revenue accounts at the tariffed rate. Non-
tariffed services provided between a carrier and its affiliate pursuant 
to publicly-filed agreements submitted to a state commission pursuant to 
section 252(e) of the Communications Act of 1934 or statements of 
generally available terms pursuant to section 252(f) shall be recorded 
using the charges appearing in such publicly-filed agreements or 
statements. Non-tariffed services provided between a carrier and its 
affiliate that qualify for prevailing price valuation, as defined in 
paragraph (d) of this section, shall be recorded at the prevailing 
price. For all other services sold by or transferred from a carrier to 
its affiliate, the services shall be recorded at no less than the higher 
of fair market value and fully distributed cost. For all other services 
sold by or transferred to a carrier from its affiliate, the services 
shall be recorded at no more than the lower of fair market value and 
fully distributed cost.
    (1) Floor. When services are sold by or transferred from a carrier 
to an affiliate, the higher of fair market value and fully distributed 
cost establishes a floor, below which the transaction cannot be 
recorded. Carriers may record the transaction at an amount equal to or 
greater than the floor, so long as that action complies with the 
Communications Act of 1934, as amended, Commission rules and orders, and 
is not otherwise anti-competitive.
    (2) Ceiling. When services are purchased from or transferred from an 
affiliate to a carrier, the lower of fair market value and fully 
distributed cost establishes a ceiling, above which the transaction 
cannot be recorded. Carriers may record the transaction at an amount 
equal to or less than the ceiling, so long as that action complies with 
the Communications Act of 1934, as amended, Commission rules and orders, 
and is not otherwise anti-competitive.
    (3) Threshold. For purposes of this section, carriers are required 
to make a good faith determination of fair market value for a service 
when the total aggregate annual value of that service reaches or exceeds 
$500,000, per affiliate. When a carrier reaches or exceeds the $500,000 
threshold for a particular service for the first time, the carrier must 
perform the market valuation and value the transaction in accordance 
with the affiliate transactions rules on a going-forward basis. All 
services received by a carrier from its affiliate(s) that exist solely 
to provide services to members of the carrier's corporate family shall 
be recorded at fully distributed cost.
    (d) In order to qualify for prevailing price valuation in paragraphs 
(b) and (c) of this section, sales of a particular asset or service to 
third parties must encompass greater than 25 percent of the total 
quantity of such product or service sold by an entity. Carriers shall 
apply this 25 percent threshold on an asset-by-asset and service-by-
service basis, rather than on a product-line or service-line basis. In 
the case of transactions for assets and services subject to section 272, 
a BOC may record such transactions at prevailing price regardless of 
whether the 25 percent threshold has been satisfied.
    (e) Income taxes shall be allocated among the regulated activities 
of the carrier, its nonregulated divisions, and members of an affiliated 
group. Under circumstances in which income taxes are determined on a 
consolidated basis by the carrier and other members of the affiliated 
group, the income tax expense to be recorded by the carrier shall be the 
same as would result if determined for the carrier separately for all 
time periods, except that the tax effect of carry-back and carry-forward 
operating losses, investment tax credits, or other tax credits generated 
by

[[Page 448]]

operations of the carrier shall be recorded by the carrier during the 
period in which applied in settlement of the taxes otherwise 
attributable to any member, or combination of members, of the affiliated 
group.
    (f) Companies that employ average schedules in lieu of actual costs 
are exempt from the provisions of this section. For other organizations, 
the principles set forth in this section shall apply equally to 
corporations, proprietorships, partnerships and other forms of business 
organizations.

pledged as collateral for any of the company's long-term debt or short-
term loans or to secure performance of contracts.
    (k) Subsidiary record categories shall be maintained in order that 
the entity may separately report the amounts contained herein that 
relate to the equity method and the cost method. Such subsidiary record 
categories shall be reported as required by part 43 of this chapter.
    (l) This account shall include property subject to a lessee 
operating lease longer than one year.
    (1) An operating lease is a contract, or part of a contract, that 
conveys the right to control the use of identified property, plant and 
equipment (an identified asset) for a period of time in exchange for 
consideration.
    (2) The amounts recorded in this account at the inception of an 
operating lease shall be equal to the present value not to exceed fair 
value, at the beginning of the lease term, of minimum lease payments 
during the lease term, excluding that portion of the payments 
representing executory costs to be paid by the lessor, together with any 
profit thereon. Amounts subject to current treatment shall be included 
in Account 1350, Other current assets.
    (3) Any balance in this account relating to capitalized operating 
leases shall be excluded in any ratemaking calculations.
    (m) This account shall include the amount of lessor receivables from 
an operating lease longer than one year.
    (1) The amount recorded in this account at the inception of an 
operating lease shall be equal to the present

[[Page 453]]

value not to exceed fair value, at the beginning of the lease term, of 
minimum lease payments during the lease term, excluding that portion of 
the payments representing executory costs to be paid by the lessee, 
together with any profit thereon. Amounts subject to current settlement 
shall be included in Account 1350, Other current assets.
    (2) Any balance in this account relating to receivables associated 
with capitalized operating leases shall be excluded in any ratemaking 
calculations.

Sec.  32.1500  Other jurisdictional assets--net.

    This account shall include the cumulative impact on assets of 
jurisdictional ratemaking practices which vary from those of this 
Commission. All entries recorded in this account shall be recorded net 
of any applicable income tax effects and shall be supported by 
subsidiary records where necessary as provided for in Sec.  32.13(e) of 
subpart B.



Sec.  32.2000  Instructions for telecommunications plant accounts.

    (a) Purpose of telecommunications plant accounts. (1) The 
telecommunications plant accounts (2001 to 2007 inclusive) are designed 
to show the investment in the company's tangible and intangible 
telecommunications plant which ordinarily has a service life of more 
than one year, including such plant whether used by the company or 
others in providing telecommunications service.
    (2) The telecommunications plant accounts shall not include the cost 
or other value of telecommunications plant contributed to the company. 
Contributions in the form of money or its equivalent toward the 
construction of telecommunications plant shall be credited to the 
accounts charged with

[[Page 454]]

the cost of such construction. Amounts of non-recurring reimbursements 
based on the cost of plant or equipment furnished in rendering service 
to a customer shall be credited to the accounts charged with the cost of 
the plant or equipment. Amounts received for construction which are 
ultimately to be repaid wholly or in part, shall be credited to Account 
4300, Other long-term liabilities and deferred credits; when final 
determination has been made as to the amount to be returned, any 
unrefunded amounts shall be credited to the accounts charged with the 
cost of such construction. Amounts received for the construction of 
plant, the ownership of which rests with or will revert to others, shall 
be credited to the accounts charged with the cost of such construction. 
(Note also Account 7100, Other operating income and expense.)
    (3) When telecommunications plant ordinarily having a service life 
of more than one year is installed for temporary use in providing 
telecommunications service, it shall be accounted for in the same manner 
as plant having a service life of more than one year. This includes 
temporary installations of plant (such as poles, wire and cable) 
installed to maintain service during the progress of highway 
reconstruction or during interruptions due to storms or other 
casualties, equipment used for the training of operators, equipment used 
to provide intercepting positions in central offices to handle traffic 
for a short period following extensive system changes and similar 
installations of property used to provide telecommunications service.
    (4) [Reserved]
    (b) Telecommunications plant acquired. (1) Property, plant and 
equipment acquired from an entity, whether or not affiliated with the 
accounting company, shall be accounted for at original cost, except that 
property, plant and equipment acquired from a nonaffiliated entity 
through an acquisition or merger may be accounted for at market value at 
the time of the acquisition or merger.
    (2) The accounting for property, plant and equipment to be recorded 
at original cost shall be as follows:
    (i) The amount of money paid (or current money value of any 
consideration other than money exchanged) for the property (together 
with preliminary expenses incurred in connection the acquisition) shall 
be charged to Account 1438, Deferred maintenance, retirements, and other 
deferred charges.
    (ii) The original cost, estimated if not known, of 
telecommunications plant, governmental franchises and other similar 
rights acquired shall be charged to the applicable telecommunications 
plant accounts, Telecommunications Plant Under Construction, and 
Property Held For Future Telecommunications Use, as appropriate, and 
credited to Account 1439. When the actual original cost cannot be 
determined and estimates are used, the company shall be prepared to 
furnish the Commission with the particulars of such estimates.
    (iii) Accumulated Depreciation and amortization balances related to 
plant acquired shall be credited to Account 3100, Accumulated 
depreciation, or Account 3200, Accumulated depreciation--held for future 
telecommunications use, or Account 3400, Accumulated amortization--
tangible and debited to Account 1438. Accumulated amortization balances 
related to plant acquired which ultimately is recorded in Accounts 2005, 
Telecommunications plant adjustment, Account 2682, Leasehold 
improvements, or Account 2690, Intangibles shall be credited to these 
asset accounts, and debited to Account 1438.
    (iv) Any amount remaining in Account 1438, applicable to the plant 
acquired, shall, upon completion of the entries provided in paragraphs 
(b)(2)(i) through (b)(2)(iii) of this section, be debited or credited, 
as applicable, to Account 2007, Goodwill, or to Account 2005, 
Telecommunications plant adjustment, as appropriate.
    (3) A memorandum record shall be kept showing the amount of 
contributions in aid of construction applicable to the property acquired 
as shown by the accounts of the previous owner.
    (c) Cost of construction. (1) Telecommunications plant represents an 
economic resource which will be used to provide future services, the 
cost of which will be allocated in a rational and systematic manner to 
the future periods in which it provides benefits. In accounting for 
construction costs, the

[[Page 455]]

utility shall charge to the telecommunications plant accounts, where 
applicable, all direct and indirect costs.
    (2) Direct and indirect costs shall include, but not be limited to:
    (i) ``Labor'' includes the wages and expenses of employees directly 
engaged in or in direct charge of construction work. It includes 
expenses directly related to an employee's wages, such as worker's 
compensation insurance, payroll taxes, benefits and other similar items 
of expense.
    (ii) ``Engineering'' includes the portion of the wages and expenses 
of engineers, draftsmen, inspectors, and their direct supervision 
applicable to construction work. It includes expenses directly related 
to an employee's wages, such as worker's compensation insurance, payroll 
taxes, benefits and other similar items of expense.
    (iii) ``Material and supplies'' includes the purchase price of 
material used at the point of free delivery plus the costs of 
inspection, loading and transportation, and an equitable portion of 
provisioning expense. In determining the cost of material used, proper 
allowance shall be made for unused material, for material recovered from 
temporary structures used in performing the work involved, and for 
discounts allowed and realized in the purchase of material. This item 
does not include construction material that is stolen or rendered 
unusable due to vandalism. Such material should be charged to the 
applicable plant specific operations expense accounts.
    (iv) ``Transportation'' includes the cost of transporting employees, 
material and supplies, tools and other work equipment to and from the 
physical construction location. It includes amounts paid therefor to 
other companies or individuals and the cost of using the company's own 
motor vehicles or other transportation equipment.
    (v) ``Contract work'' includes amounts paid for work performed under 
contract or other agreement by other companies, firms or individuals; 
engineering and supervision applicable to such work; cost incident to 
the award of contracts; and the inspection of such work. The cost of 
construction work performed by affiliated companies and other details 
relating thereto shall be available from the work in progress and 
supporting records.
    (vi) ``Protection'' includes the cost of protecting the company's 
property from fire or other casualties and the cost of preventing 
damages to others or the property of others.
    (vii) ``Privileges, Permits, and Rights of way'' includes such costs 
incurred in obtaining these privileges, permits, or rights of way in 
connection with construction work, such as for use of private property, 
streets or highways. The cost of such privileges and permits shall be 
included in the cost of the work for which the privileges or permits are 
obtained, except for costs includable in Account 2111, Land, and Account 
2690, Intangibles.
    (viii) ``Taxes'' includes taxes properly includable in construction 
costs before the facilities are completed for service, which taxes are 
assessed separately from taxes on operating property or under conditions 
that permit separate identification of the amount chargeable to 
construction.
    (ix) ``Special machine service'' includes the cost of labor 
expended, materials and supplies consumed and other expenses incurred in 
the maintenance, operation and use of special and other labor saving 
machines (other than transportation equipment (such as trenching 
equipment, cable plows and pole setting trucks. Also included are 
expenditures for rental, maintenance and operation of such machines 
owned by others. When a construction job requires the purchase of 
special machines, the cost thereof, less the appraised or salvage value 
at the time of release from the job, shall be included in the cost of 
construction.
    (x) Allowance for funds used during construction (``AFUDC'') 
provides for the cost of financing the construction of 
telecommunications plant. AFUDC shall be charged to Account 2003, 
Telecommunications plant under construction, and credited to Account 
7300, Nonoperating income and expense. The rate for calculating AFUDC 
shall be determined in accordance with GAAP when implementing this 
system of accounts. The amount of interest cost capitalized in an 
accounting period

[[Page 456]]

shall not exceed the total amount of interest cost incurred by the 
company in that period.
    (xi) ``Insurance'' includes premiums paid specifically for 
protection against loss and damage in connection with the construction 
of telecommunications plant due to fire or other casualty, injury to or 
death of employees or others, damages to property of others, 
defalcations of employees and agents and the non-performance of 
contractual obligations of others.
    (xii) ``Construction services'' include the cost of telephone, 
electricity, power, construction quarters, office space and equipment 
directly related to the construction project.
    (xiii) ``Indirect construction costs'' shall include indirect costs 
such as general engineering, supervision and support. Such costs, in 
addition to direct supervision, shall include indirect plant operations 
and engineering supervision up to, but not including, supervision by 
executive officers whose pay and expenses are chargeable to Account 
6720, General and administrative. The records supporting the entries for 
indirect construction costs shall be kept so as to show the nature of 
the expenditures, the individual jobs and accounts charged, and the 
bases of the distribution. The amounts charged to each plant account for 
indirect costs shall be readily determinable. The instructions contained 
herein shall not be interpreted as permitting the addition to plant of 
amounts to cover indirect costs based on arbitrary allocations.
    (xiv) The cost of construction shall not include any amounts 
classifiable as Corporate Operations Expense.
    (d) Telecommunications plant retired. (1) Telecommunications plant 
accounts shall at all times disclose the original cost of all property 
in service. When any item of property subject to plant retirement 
accounting is worn out, lost, sold, destroyed, abandoned, surrendered 
upon lapse of title, becomes permanently unserviceable, is withdrawn or 
for any other reason is retired from service, the plant accounts 
applicable to that item shall be credited with the original cost of the 
plant retired whether replaced or not (except as provided for minor 
items in paragraph (d)(2)(ii) of this section). Normally, these 
retirement credits with respect to such plant as entire buildings, 
entire central offices, all plant abandoned and any large sections of 
plant withdrawn from service, shall be entered in the accounts for the 
month in which use of the property ceased. For any other plant withdrawn 
from service, the retirement credits shall be entered no later than the 
next succeeding month. Literal compliance with the provision for timing 
of entries with respect to property amounting to less than $50,000 
retired under any one project is not required if an unreasonable amount 
of recordkeeping and estimating of quantities, original costs and 
salvage is necessary. The retirement entry shall refer to the continuing 
property record, or records supplemental thereto, from which the cost 
was obtained (note also paragraph (d)(3) of this section). Every company 
shall establish procedures which will ensure compliance with these 
requirements.
    (2) To avoid undue refinement, depreciable telecommunications plant 
shall be accounted for as follows:
    (i) Retirement units: This group includes major items of property, a 
representative list of which shall be prescribed by this Commission. In 
lieu of the retirement units prescribed with respect to a particular 
account, a company may, after obtaining specific approval by this 
Commission, establish and maintain its own list of retirement units for 
a portion or all of the plant in any such account. For items included on 
the retirement units list, the original cost of any such items retired 
shall be credited to the plant account and charged to Account 3100 
Accumulated Depreciation, whether or not replaced. The original cost of 
retirement units installed in place of property retired shall be charged 
to the applicable telecommunications plant account.
    (ii) Minor items: This group includes any part or element of plant 
which is not designated as a retirement unit. The original cost of a 
minor item of property when included in the specific or average cost for 
a retirement unit or units requires no separate credit to the 
telecommunications plant account when such a minor item is retired. The

[[Page 457]]

cost of replacement shall be charged to the account applicable for the 
cost of repairs of the property. However, if the replacement effects a 
substantial betterment (the primary aim of which is to make the property 
affected more useful, of greater durability, of greater capacity or more 
economical in operation), the excess cost of such a replacement, over 
the estimated cost at the then current prices of replacement without 
betterment of the minor items being retired, shall be charged to the 
applicable telecommunications plant account.
    (3) The cost of property to be retired shall be the amount at which 
property is included in the telecommunications plant accounts. However, 
when it is impracticable to determine the cost of each item due to the 
relatively large number or small cost of such items, the average cost of 
all the items covered by an appropriate subdivision of the account shall 
be used in determining the cost to be assigned to such items when 
retired. The method used in determining average cost must give due 
regard to the quantity, vintage, size and kind of items, the area in 
which they were installed and their classification in other respects. 
Average cost may be applied in retirement of such items as poles, wire, 
cable, cable terminals, conduit and booths. Any company may use average 
cost of property installed in a year or band of years as approved by the 
Commission. It should be understood, however, that the use of average 
costs shall not relieve the company of the requirement for maintaining 
its continuing property records to show, where practicable, dates of 
installation and removal for purposes of mortality studies. (See Sec.  
32.2000(f) of this subpart, Standard Practices for Establishing and 
Maintaining Continuing Property Records.)
    (4) The accounting for the retirement of property, plant and 
equipment shall be as provided above except that amounts in Account 
2111, Land, and amounts for works of art recorded in Account 2122, 
Furniture, shall be treated at disposition as a gain or loss and shall 
be credited or debited to Account 7100, Other operating income and 
expense, as applicable. If land or artwork is retained by the company 
and held for sale, the cost shall be charged to Account 2006, 
Nonoperating plant.
    (5) When the telecommunications plant is sold together with traffic 
associated therewith, the original cost of the property shall be 
credited to the applicable plant accounts and the estimated amounts 
carried with respect thereto in the accumulated depreciation and 
amortization accounts shall be charged to such accumulated accounts. The 
difference, if any, between the net amount of such debit and credit 
items and the consideration received (less commissions and other 
expenses of making the sale) for the property shall be included in 
Account 7300, Nonoperating income and expense. The accounting for 
depreciable telecommunications plant sold without the traffic associated 
therewith shall be in accordance with the accounting provided in Sec.  
32.3100(c).
    (e) Basic property records. (1) The basic property records are that 
portion of the total property accounting system which preserves the 
following detailed information:
    (i) The identity, vintage, location and original cost of units of 
property;
    (ii) Original and ongoing transactional data (plant account 
activity) in terms of such units; and
    (iii) Any other specific financial and cost accounting information 
not properly warranting separate disclosure as an account or subaccount 
but which is needed to support regulatory, cost, tax, management and 
other specific accounting information needs and requirements.
    (2) The basic property records must be: (i) Subject to internal 
accounting controls, (ii) auditable, (iii) equal in the aggregate to the 
total investment reflected in the financial property control accounts as 
well as the total of the cost allocations supporting the determination 
of cost-of-service at any particular point in time, and (iv) maintained 
throughout the life of the property.
    (3) The basic property records shall consist of (i) continuing 
property records and (ii) records supplemental thereto which together 
reveal clearly, by accounting area, the detailed and

[[Page 458]]

systematically summarized information necessary to meet fully the 
requirements of paragraphs (e)(1) and (e)(2) of this section.
    (4) Companies shall establish and maintain basic property records 
for each class of property recorded in the several plant accounts which 
comprise the balance sheet Account 2001, Telecommunications Plant In 
Service, Account 2002, Property Held for Future Telecommunications Use, 
and Account 2006, Nonoperating Plant.
    (5) The company shall notify the Commission of a plan for the basic 
property record as follows:
    (i) Not later than June 30 of the year following that in which it 
becomes subject to this system of accounts, the company shall file with 
the Commission two (2) copies of a complete plan of the method to be 
used in the compilation of a basic property record with respect to each 
class of property. The plan shall include a list of proposed accounting 
areas accompanied by description of the boundaries of each area as 
defined in accordance with the requirements of Sec.  32.2000(f)(1) (i) 
and (ii) of this subpart. The plan shall also include a list of property 
record units proposed for use under each regulated plant account. These 
property record units shall be selected such that the requirements of 
Sec.  32.2000(f)(2) (i), (ii) and (iii) of this subpart can be 
satisfied.
    (ii) The company shall submit to the Commission one copy of any 
major proposed changes in its basic property record plan at least 30 
days before the effective date of the proposed changes.
    (6) The company shall prepare and maintain the basic property record 
as follows:
    (i) Not later than June 30 of the year following that in which the 
company becomes subject to this system of accounts, begin the 
preparation of a basic property record.
    (ii) Complete within two years of the prescribed beginning date, 
basic property records for all property as of the end of the preceding 
calendar year.
    (iii) Promptly process in the basic property records all property 
changes affecting periods subsequent to initial establishment of the 
basic property record.
    (7) The basic property record components (see paragraph (c) of this 
section) shall be arranged in conformity with the regulated plant 
accounts prescribed in this section of accounts as follows:
    (i) The continuing property records shall be compiled on the basis 
of original cost (or other book cost consistent with this system of 
accounts). The continuing property records shall be maintained as 
prescribed in Sec.  32.2000(f)(2)(iii) of this subpart in such manner as 
will meet the following basic objectives:
    (A) Provide for the verification of property record units by 
physical examination.
    (B) Provide for accurate accounting for retirements.
    (C) Provide data for use in connection with depreciation studies.
    (ii) The records supplemental to the continuing property records 
shall disclose such service designations, usage measurement criteria, 
apportionment factors, or other data as may be prescribed by the 
Commission in this part or other parts of its Rules and Regulations. 
Such data are subject to the same general controls and standards for 
auditability and support as are all other elements of the basic property 
records.
    (8) Notwithstanding any other provision of this part concerning 
continuing property records, carriers subject to price cap regulations 
set forth in part 61 of this chapter shall maintain property records 
necessary to track substantial assets and investments in an accurate, 
auditable manner that enables them to verify their accounting books, 
make such property information available to the Commission upon request, 
and ensure the maintenance of such data.
    (f) Standard practices for establishing and maintaining continuing 
property records--(1) Accounting area. (i) The continuing property 
record, as related to each primary plant account, shall be established 
and maintained by subaccounts for each accounting area. An accounting 
area is the smallest territory of the company for which accounting 
records of investment are maintained for all plant accounts within the 
area. Areas already established for administrative, accounting, 
valuation, or other purposes may be adopted for this

[[Page 459]]

purpose when appropriate. In no case shall the boundaries of accounting 
areas cross either State lines or boundaries prescribed by the 
Commission.
    (ii) In determining the limit of each area, consideration shall be 
given to the quantities of property, construction conditions, operating 
districts, county and township lines, taxing district boundaries, city 
limits, and other political or geographical limits, in order that the 
area adopted may have maximum adaptability, within the confines of 
practicability, for both the company's purpose and those of Federal, 
State, and municipal authorities.
    (2) Property record units. (i) In each of the established accounting 
areas, the ``property record units'' which are to be maintained in the 
continuing property record shall be set forth separately, classified by 
size and type with the amount of original cost (or other appropriate 
book cost) associated with such units. When a list of property record 
units has been accepted by the Commission, they shall become the units 
referred to in this statement of standard practices. Such units shall 
apply to only the regulated portion of this system of accounts.
    (ii) When it is found necessary to revise this list because of the 
addition of units used in providing new types of service, or new units 
resulting from improvements in technology, or because of the grouping or 
elimination of units which no longer merit separate recognition as 
property record units, one copy of such changes shall be submitted to 
the Commission. Upon appropriate showing by the company, the Commission 
may specifically exempt the company from these filing requirements.
    (iii) The continuing property record shall reveal the description, 
location, date of placement, the essential details of construction, and 
the original cost (note also paragraph (f)(3) of this section) of the 
property record units. The continuing property records shall be compiled 
on the basis of original cost (or other book cost consistent with this 
system of accounts) and maintained in such manner as will provide for 
the verification of property record units by physical examination. The 
continuing property record and other underlying records of construction 
costs shall be so maintained that, upon retirement of one or more 
retirement units or of minor items without replacement when not included 
in the costs of retirement units, the actual cost or a reasonably 
accurate estimate of the cost of the plant retired can be determined.
    (3) Methods of determining original cost of property record units. 
The original cost of the property record units shall be determined by 
analyses of the construction costs incurred as shown by completion 
reports and other data, accumulated in the respective construction work 
orders or authorizations. Costs shall be allocated to and associated 
with the property record units to facilitate accounting for retirements. 
The original cost of property record units shall be determined by unit 
identification or averaging as described in paragraphs (f)(3) (i) and 
(ii) of this section.
    (i) Unit identification. Cost shall be identified and maintained by 
specific location for property record units contained within certain 
regulated plant accounts or account groupings such as Land, Buildings, 
Central Office Assets, Motor Vehicles, garage work equipment included in 
Account 2114, Tools and other work equipment, and Furniture. In 
addition, units involved in any unusual or special type of construction 
shall be recorded by their specific location costs (note also Sec.  
32.2000(f)(3)(ii)(B)).
    (ii) Averaging. (A) Average costs may be developed for plant 
consisting of a large number of similar units such as terminal 
equipment, poles, wire, cable, cable terminals, conduit, furniture, and 
work equipment. Units of similar size and type within each specified 
accounting area and regulated plant account may be grouped. Each such 
average cost shall be set forth in the continuing property record of the 
units with which it is associated.
    (B) The averaging of costs permitted under the provisions of the 
foregoing paragraph is restricted to plant installed in a particular 
vintage or band of years incurred within an accounting area. This 
paragraph does not permit the inclusion of the cost of units involved in 
any unusual or special type

[[Page 460]]

of construction. The units involved in such unusual or special type of 
construction shall be recorded at cost by location.
    (4) Estimates. In cases where the actual original cost of property 
cannot be ascertained, such as pricing an inventory for the initial 
entry of a continuing property record or the pricing of an acquisition 
for which a continuing property record has not been maintained, the 
original cost may be estimated. Any estimated original cost shall be 
consistent with the accounting practices in effect at the time the 
property was constructed.
    (5) Identification of property record units. There shall be shown in 
the continuing property record or in record supplements thereof, a 
complete description of the property records units in such detail as to 
identify such units. The description shall include the identification of 
the work order under which constructed, the year of installation (unless 
not determinable per Sec.  32.2000(f)(4) of this subpart, specific 
location of the property within each accounting area in such manner that 
it can be readily spot-checked for proof of physical existence, the 
accounting company's number or designation, and any other description 
used in connection with the determination of the original cost. 
Descriptions of units of similar size and type shall follow prescribed 
groupings.
    (6) Reinstalled units. When units to which average costs are not 
applied, i.e., specific and fixed location units, are removed or retired 
and subsequently reinstalled, the date when the unit was first charged 
to the appropriate plant account shall, when required for adequate 
service life studies and reasonably accurate retirement accounting, be 
shown in addition to the date of reinstallation.
    (7) Age and service life of property. The continuing property record 
shall disclose the age of existing property and the supporting records 
shall disclose the service life of property retired. Exceptions from 
this requirement for any property record unit shall be submitted to the 
Commission for approval.
    (8) Reference to sources of information. There shall be shown by 
appropriate reference the source of all entries. All drawings, 
computations, and other detailed records which support quantities and 
costs or estimated costs shall be retained as a part of or in support of 
the continuing property record.
    (9) Jointly owned property. (i) With respect to jointly owned 
property, there shall be shown in the continuing property record or 
records supplemental thereto:
    (A) The identity of all joint owners.
    (B) The percentage owned by the accounting company.
    (ii) When regulated plant is constructed under arrangements for 
joint ownership, the amount received by the constructing company from 
the other joint owner or owners shall be credited as a reduction of the 
gross cost of the plant in place.
    (iii) When a sale of a part interest in regulated plant is made, the 
fractional interest sold shall be treated as a retirement and the amount 
received shall be treated as salvage. The continuing property record or 
records supplemental thereto shall be so maintained as to identify 
separately retirements of this nature from physical retirements of 
jointly owned plant.
    (iv) If jointly owned regulated property is substantial in relation 
to the total of the same kind of regulated property owned wholly by the 
company, such jointly owned regulated property shall be appropriately 
segregated in the continuing property record.
    (g) Depreciation accounting--(1) Computation of depreciation rates. 
(i) Unless otherwise provided by the Commission, either through prior 
approval or upon prescription by the Commission, depreciation percentage 
rates shall be computed in conformity with a group plan of accounting 
for depreciation and shall be such that the loss in service value of the 
property, except for losses excluded under the definition of 
depreciation, may be distributed under the straight-line method during 
the service life of the property.
    (ii) In the event any composite percentage rate becomes no longer 
applicable, revised composite percentage rates shall be computed in 
accordance with paragraph (g)(1)(i) of this section.

[[Page 461]]

    (iii) The company shall keep such records of property and property 
retirements as will allow the determination of the service life of 
property which has been retired, or facilitate the determination of 
service life indications by mortality, turnover, or other appropriate 
methods. Such records will also allow the determination of the 
percentage of salvage value and cost of removal for property retired 
from each class of depreciable plant.
    (2) Depreciation charges. (i) A separate annual percentage rate for 
each depreciation category of telecommunications plant shall be used in 
computing depreciation charges.
    (ii) Companies, upon receiving prior approval from this Commission, 
or, upon prescription by this Commission, shall apply such depreciation 
rate, except where provisions of paragraph (g)(2)(iv) of this section 
apply, as will ratably distribute on a straight line basis the 
difference between the net book cost of a class or subclass of plant and 
its estimated net salvage during the known or estimated remaining 
service life of the plant.
    (iii) Charges for currently accruing depreciation shall be made 
monthly to the appropriate depreciation accounts, and corresponding 
credits shall be made to the appropriate depreciation reserve accounts. 
Current monthly charges shall normally be computed by the application of 
one-twelfth of the annual depreciation rate to the monthly average 
balance of the associated category of plant. The average monthly balance 
shall be computed using the balance as of the first and last days of the 
current month.
    (iv) In certain circumstances and upon prior approval of this 
Commission, monthly charges may be determined in total or in part 
through the use of other methods whereby selected plant balances or 
portions thereof are ratably distributed over periods prescribed by this 
Commission. Such circumstances could include but not be limited to 
factors such as the existence of reserve deficiencies or surpluses, 
types of plant that will be completely retired in the near future, and 
changes in the accounting for plant. Where alternative methods have been 
used in accordance with this subparagraph, such amounts shall be applied 
separately or in combination with rates determined in accordance with 
paragraph (g)(2)(ii) of this section.
    (3) Acquired depreciable plant. When acquired depreciable plant 
carried in Account 1438, Deferred maintenance, retirements and other 
deferred charges, is distributed to the appropriate plant accounts, 
adjusting entries shall be made covering the depreciation charges 
applicable to such plant for the period during which it was carried in 
Account 1438.
    (4) Plant Retired for Nonrecurring Factors not Recognized in 
Depreciation Rates.
    (i) A retirement will be considered as nonrecurring (extraordinary) 
only if the following criteria are met:
    (A) The impending retirement was not adequately considered in 
setting past depreciation rates.
    (B) The charging of the retirement against the reserve will unduly 
deplete that reserve.
    (C) The retirement is unusual such that similar retirements are not 
likely to recur in the future.
    (5) Upon direction or approval from this Commission, the company 
shall credit Account 3100, Accumulated Depreciation, and charge Account 
1438, Deferred Maintenance, retirements and other deferred charges, with 
the unprovided-for loss in service value. Such amounts shall be 
distributed from Account 1438 to Account 6561, Depreciation expense--
Telecommunications plant in service, or Account 6562, Depreciation 
expense--property held for future telecommunications use, over such 
period as this Commission may direct or approve.
    (h) Amortization accounting. (1) Unless otherwise provided by this 
Commission, either through approval, or upon prescription by this 
Commission, amortization shall be computed on the straight-line method, 
i.e., equal annual amounts shall be applied. The cost of each type asset 
shall be amortized on the basis the estimated life of that asset and 
shall not be written off in the accounting period in which the asset is 
acquired. A reasonable estimate of the useful life may be based on the 
upper or lower limits even though a fixed existence is not determinable. 
However,

[[Page 462]]

the period of amortization shall not exceed forty years.
    (2) In the event any estimated useful life becomes no longer 
applicable, a revised estimated useful life shall be determined in 
accordance with paragraph (h)(1) of this section.
    (3) Amortization charges shall be made monthly to the appropriate 
amortization expense accounts and corresponding credits shall be made to 
accounts 2005, 2682, 2690, and 3410, as appropriate. Monthly charges 
shall be computed by the application of one-twelfth to the annual 
amortization amount.
    (4) The company shall keep such records as will allow the 
determination of the useful life of the asset.

               Subpart D_Instructions For Revenue Accounts



Sec.  32.4999  General.

    (a) Purpose of revenue accounts. The revenue accounts are intended 
to include the actual cash inflows (or equivalents) that have or will 
occur as a result of the company's ongoing major or central operations 
during the period. They will include the revenues which arise from 
furnishing regulated telecommunications services to others, from 
directory advertising, rentals of telecommunications assets and from 
providing other services which are directly associated with the 
provision of regulated telecommunications services.
    (b) Deductions from revenue. Corrections of overcharges, authorized 
refunds of overcollections previously credited to revenue, authorized 
refunds and adjustments on account of failure in service, and other 
corrections shall be charged to the revenue account previously credited 
with the amounts involved.
    (c) Commissions. Commissions paid to others or employees in place of 
compensation or salaries for services rendered, such as public telephone 
commissions, shall be charged to Account 6623, Customer services, and 
not to the revenue accounts. Other commissions shall be charged to the 
appropriate expense accounts.
    (d) Revenue recognition. Credits shall be made to the appropriate 
revenue accounts when such revenue is actually earned. When the billing 
cycle encompasses more than one accounting period, adjustments are 
necessary to properly recognize the revenue applicable to the current 
accounting period under report. Revenues recorded under the terms of 
two-tier contracts or other variable payment plans should be deferred, 
if necessary, and recognized ratably with expenses over the terms of the 
related contract. Any amounts deferred shall be credited to Account 
4300, Other long-term liabilities and deferred credits.
    (e) Contractual arrangements. Charges and credits resulting from 
activities associated with the provisions of regulated 
telecommunications services shall be recorded in a manner consistent 
with the nature of the underlying contractual arrangements. The charges 
and credits resulting from expense sharing or apportionment arrangements 
associated with the provision of regulated telecommunications services 
shall be recorded in the detailed regulated accounts. Charges and 
credits resulting from revenue settlement agreements or other revenue 
pooling arrangements associated with the provision of regulated 
telecommunications services shall be included in the appropriate revenue 
accounts. Those charges and credits resulting from contractual revenue 
pooling and/or sharing agreements shall be recorded in each prescribed 
revenue account and prescribed subsidiary record categories thereof to 
the extent that each is separately identifiable in the settlement 
process. It is not intended that settlement amounts be allocated or 
generally spread to the individual revenue accounts where they are not 
separately identifiable in the settlement process. When the settlement 
amounts are not identifiable by a revenue account they shall be recorded 
in Account 5060, Other basic area revenue, 5105, Long distance message 
revenue, or 5200, Miscellaneous revenue, as appropriate.
    (f) Subsidiary records--jurisdictional subdivisions and 
interconnection. Subsidiary record categories shall be maintained in 
order that the company may separately report revenues derived from 
charges imposed under intrastate,

[[Page 481]]

interstate and international tariff filings. Such subsidiary record 
categories shall be reported as required by part 43 of this chapter.
    (g) Structure of revenue accounts. (1) The revenue section of the 
system of accounts shall be organized by revenue group summary account, 
account and subsidiary record category (if required).
    (2) The revenue section of this system of accounts shall be 
comprised of six major groups--Local Network Services Revenues, Network 
Access Services Revenues, Long Distance Network Services Revenues, 
Miscellaneous Revenues, Nonregulated revenues, and Uncollectible 
Revenues, which shall be considered as a revenue group for the purposes 
of the construction of the system.
    (3) Accounts shall be maintained as prescribed in this Section 
subject to the conditions described in section 32.13 of subpart B. In 
certain instances, subsidiary record categories may be required below 
the account level by this system of accounts or by Commission order.
    (h) Local Network Services revenues. Local Network Services revenues 
(Accounts 5001 through 5060) shall include revenues derived from the 
provision of service and equipment entirely within the basic service 
area. That area is defined as the normal boundaries for local calling 
plus Extended Area Service (EAS) boundaries as they apply to that 
service. It includes revenues derived from both local private network 
service and local public network services as well as from customer 
premises facilities services. Local revenues include associated charges 
such as one-time service connection or termination charges and secondary 
features such as call waiting.
    (i) Network Access revenues. (1) Network Access revenues (Accounts 
5081-5083) shall include revenues derived from the provision of exchange 
access services to an interexchange carrier or to an end user of 
telecommunications services beyond the exchange carrier's network.
    (2) Billing and collections service provided under exchange access 
tariffs shall be included in the Miscellaneous Revenues Group.
    (j) Long Distance Network Service revenues. Long Distance Network 
Service revenues shall include revenues derived from the provision of 
services beyond the basic service area, whether message or flat-rate and 
including public network switching as well as private.
    (k) Miscellaneous revenues. Miscellaneous revenues are those 
revenues derived from the provision of regulated products and services 
provided under tariff or contract but not contained elsewhere. They 
shall also include operating revenue derived from activities performed 
incident to the company's tariffed telecommunications operations which, 
though non-tariffed, are included in the regulatory process.
    (l) Nonregulated revenues. The nonregulated revenue account shall be 
used for nonregulated operating revenues when a nonregulated activity 
involves the common or joint use of assets or resources in the provision 
of regulated and nonregulated products or services as required in Sec.  
32.23(c) of this subpart. Revenues from nontariffed activities offered 
incidental to tariffed services may be accounted for as regulated 
revenues, provided the activities are outgrowths of regulated operations 
and the revenues do not exceed, in the aggregate, one percent of total 
revenues for three consecutive years. Such activities must be listed in 
the Commission-approved Cost Allocation Manual for any company required 
to file a Cost Allocation Manual.
    (m) Uncollectible revenues. Uncollectible revenues shall include 
amounts originally credited to the revenue accounts which have proved 
impracticable of collection.
    (n) Revenue accounts to be maintained.

October 19, 1992 to the given year. The indexed revenue threshold for a 
given year shall be determined by multiplying $100 million by the ratio 
of the annual value of the GDP-CPI for the given year to the estimated 
seasonally adjusted GDP-CPI on October 19, 1992. The indexed revenue

    Salvage value means the amount received for property retired, if 
sold, or if retained for reuse, the amount at which the material 
recovered is chargeable to Account 1220, Material and Supplies, or other 
appropriate account.

                            Subpart A_General



Sec.  36.1  General.

    (a) This part contains an outline of separations procedures for 
telecommunications companies on the station-to-station basis. These 
procedures are applicable either to property costs, revenues, expenses, 
taxes, and reserves as recorded on the books of the company or to 
estimated amounts.
    (1) Where a value basis is used instead of book costs, the ``costs'' 
referred to are the ``values'' of the property derived from the 
valuation.
    (b) The separations procedures set forth in this part are designed 
primarily for the allocation of property costs, revenues, expenses, 
taxes and reserves between state and interstate jurisdictions. For 
separations, where required, of the state portion between exchange and 
toll or for separations of individual exchanges or special services, 
further analyses and studies may be required to adapt the procedures to 
such additional separations.
    (c) The fundamental basis on which separations are made is the use 
of telecommunications plant in each of the operations. The first step is 
the assignment of the cost of the plant to categories. The basis for 
making this assignment is the identification of the plant assignable to 
each category and the determination of the cost of the plant so 
identified. The second step is the apportionment of the cost of the 
plant in each category among the operations by direct assignment where 
possible, and all remaining costs are assigned by the application of 
appropriate use factors.
    (d) In assigning book costs to categories, the costs used for 
certain plant classes are average unit costs which equate to all book 
costs of a particular account or subaccount; for other plant classes, 
the costs used are those which either directly approximate book cost 
levels or which are equated to match total book costs at a given 
location.
    (e) The procedures outlined herein reflect ``short-cuts'' where 
practicable and where their application produces substantially the same 
separations results as would be obtained by the use of more detailed 
procedures, and they assume the use of records generally maintained by 
Telecommunications Companies.
    (f) The classification to accounts of telecommunications property, 
revenues, expenses, etc., set forth in this manual is that prescribed by 
the Federal Communications Commission's Uniform System of Accounts for 
Telecommunications Companies.
    (g) In the assignment of property costs to categories and in the 
apportionment of such costs among the operations, each amount so 
assigned and apportioned is identified as to the account classification 
in which the property is included. Thus, the separated results are 
identified by property accounts and apportionment bases are provided for 
those expenses which are separated on the basis of the apportionment of 
property costs. Similarly, amounts of revenues and expenses assigned 
each of the operations are identified as to account classification.
    (h) The separations procedures described in this part are not to be 
interpreted as indicating what property, revenues, expenses and taxes, 
or what items carried in the income, reserve and retained earnings 
accounts, should or should not be considered in any investigation or 
rate proceeding.



Sec.  36.2  Fundamental principles underlying procedures.

    (a) The following general principles underlie the procedures 
outlined in this part:
    (1) Separations are intended to apportion costs among categories or 
jurisdictions by actual use or by direct assignment.

[[Page 505]]

    (2) Separations are made on the ``actual use'' basis, which gives 
consideration to relative occupancy and relative time measurements.
    (3) In the development of ``actual use'' measurements, measurements 
of use are (i) determined for telecommunications plant or for work 
performed by operating forces on a unit basis (e.g., conversation-
minute-kilometers per message, weighted standard work seconds per call) 
in studies of traffic handled or work performed during a representative 
period for all traffic and (ii) applied to overall traffic volumes, 
i.e., 24-hour rather than busy-hour volumes.
    (b) Underlying the procedures included in this manual for the 
separation of plant costs is an over-all concept which may be described 
as follows:
    (1) Telecommunications plant, in general, is segregable into two 
broad classifications, namely, (i) interexchange plant, which is plant 
used primarily to furnish toll services, and (ii) exchange plant, which 
is plant used primarily to furnish local services.
    (2) Within the interexchange classification, there are three broad 
types of plant, i.e., operator systems, switching plant, and trunk 
transmission equipment. Within the exchange classification there are 
four board types of plant, i.e., operator systems, switching plant, 
truck equipment and subscriber plant. Subscriber plant comprises lines 
to the subscriber.
    (3) In general, the basis for apportioning telecommunications plant 
used jointly for state and interstate operations are:
    (i) Operator work time expressed in weighted standard work seconds 
is the basis for measuring the use of operator systems.
    (ii) Holding-time-minutes is the basis for measuring the use of 
local and toll switching plant.
    (iii) Conversation-minute-kilometers or conversation minutes is the 
basis for measuring the use of interexchange circuit plant and holding-
time minutes is the basis for measuring the use of exchange trunk plant. 
While the use of holding-time-minute-kilometers is the basic fundamental 
allocation factor for interexchange circuit plant and exchange trunk 
plant, the use of conversation-minute-kilometers or conversation-minutes 
for the allocation of interexchange circuit plant and holding-time 
minutes for the allocation of exchange trunk plant are considered 
practical approximations for separations between state and interstate 
operations when related to the broad types of plant classifications used 
herein.
    (iv) Message telecommunications subscriber plant shall be 
apportioned on the basis of a Gross Allocator which assigns 25 percent 
to the interstate jurisdiction and 75 percent to the state jurisdiction.
    (c) Property rented to affiliates, if not substantial in amount, is 
included as used property of the owning company with the associated 
revenues and expenses treated consistently: Also such property rented 
from affiliates is not included with the used property of the company 
making the separations; the rent paid is included in its expenses. If 
substantial in amount, the following treatment is applied:
    (1) In the case of property rented to affiliates, the property and 
related expenses and rent revenues are excluded from the telephone 
operations of the owning company, and
    (2) In the case of property rented from affiliates, the property and 
related expenses are included with, and the rent expenses are excluded 
from, the telephone operations of the company making the separation.
    (d) Property rented to or from non-affiliates is usually to be 
included as used property of the owning company with the associated 
revenues and expenses treated consistently. In the event the amount is 
substantial, the property involved and the revenues and expenses 
associated therewith may be excluded from or included in the 
telecommunications operations of the company. When required, the cost of 
property rented to or from non-affiliates is determined using procedures 
that are consistent with the procedures for the allocation of costs 
among the operations.
    (e) Costs associated with services or plant billed to another 
company which have once been separated under procedures consistent with 
general principles set forth in this part, and are

[[Page 506]]

thus identifiable as entirely interstate or State in nature, shall be 
directly assigned to the appropriate operation and jurisdiction.

Sec.  36.3  Freezing of jurisdictional separations category relationships
and/or allocation factors.

    (a) Effective July 1, 2001, through December 31, 2024, all local 
exchange carriers subject to part 36 rules shall apportion costs to the 
jurisdictions using their study area and/or exchange specific 
jurisdictional allocation factors calculated during the twelve-month 
period ending December 31, 2000, for each of the categories/sub-
categories as specified herein. Direct assignment of private line 
service costs between jurisdictions shall be updated annually. Other 
direct assignment of investment, expenses, revenues or taxes between 
jurisdictions shall be updated annually. Local exchange carriers that 
invest in telecommunications plant categories during the period July 1, 
2001, through December 31, 2024, for which it had no separations 
allocation factors for the twelve-month period ending December 31, 2000, 
shall apportion that investment among the jurisdictions in accordance 
with the separations procedures in effect as of December 31, 2000 for 
the duration of the freeze.
    (b) Effective July 1, 2001, through December 31, 2024, local 
exchange carriers subject to price cap regulation, pursuant to Sec.  
61.41 of this chapter, shall assign costs from the accounts under part 
32 of this chapter (part 32 account(s)) to the separations categories/
sub-categories, as specified herein, based on the percentage 
relationships of the categorized/sub-categorized costs to their 
associated part 32 accounts for the twelve-month period ending December 
31, 2000. If a part 32 account for separations purposes is categorized 
into more than one category, the percentage relationship among the 
categories shall be utilized as well. Local exchange carriers that 
invest in types of telecommunications plant during the period July 1, 
2001, through December 31, 2024, for which it had no separations 
category investment for the twelve-month period ending December 31, 
2000, shall assign such investment to separations categories in 
accordance with the separations procedures in effect as of December 31, 
2000. Local exchange carriers not subject to price cap regulation, 
pursuant to Sec.  61.41 of this chapter, may elect to be subject to the 
provisions of this paragraph (b). Such election must be made prior to 
July 1, 2001. Any local exchange carrier that is subject to Sec.  
69.3(e) of this chapter and that elected to be subject to this paragraph 
(b) may withdraw from that election by notifying the Commission by May 
1, 2019, of its intent to withdraw from that election, and that 
withdrawal will be effective as of July 1, 2019. Any local exchange 
carrier that participates in an Association tariff, pursuant to 
Sec. Sec.  69.601 through 69.610 of this chapter, and that elected to be 
subject to this paragraph (b) may withdraw from that election by 
notifying the Association by March 1, 2019, of such intent. Subject to 
these two exceptions, local exchange carriers that previously elected to 
become subject to this paragraph (b) shall not be eligible to withdraw 
from such regulation for the duration of the freeze.
    (c) Effective July 1, 2001, through December 31, 2024, any local 
exchange carrier that sells or otherwise transfers exchanges, or parts 
thereof, to another carrier's study area shall continue to utilize the 
factors and, if applicable, category relationships as specified in 
paragraphs (a) and (b) of this section.
    (d) Effective July 1, 2001, through December 31, 2024, any local 
exchange carrier that buys or otherwise acquires exchanges or part 
thereof, shall calculate new, composite factors and, if applicable, 
category relationships based on a weighted average of both the seller's 
and purchaser's factors and category relationships calculated pursuant 
to paragraphs (a) and (b) of this section. This weighted average should 
be based on the number of access lines currently being served by the 
acquiring carrier and the number of access lines in the acquired 
exchanges.

[[Page 507]]

    (1) To compute the composite allocation factors and, if applicable, 
the composite category percentage relationships of the acquiring 
company, the acquiring carrier shall first sum its existing (pre-
purchase) access lines (A) with the total access lines acquired from 
selling company (B). Then, multiply its factors and category 
relationship percentages by (A/(A + B)) and those of the selling company 
by (B/(A + B)) and sum the results.
    (2) For carriers subject to a freeze of category relationships, the 
acquiring carrier should remove all categories of investment from the 
selling carrier's list of frozen category relationships where no such 
category investment exists within the sold exchange(s). The seller's 
remaining category relationships must then be increased proportionately 
to total 100 percent. Then, the adjusted seller's category relationships 
must be combined with those of the acquiring carrier as specified in 
Sec.  36.3(d)(1) to determine the category relationships for the 
acquiring carrier's post-transfer study area.
    (e) Any local exchange carrier study area converting from average 
schedule company status, as defined in Sec.  69.605(c) of this chapter, 
to cost company status during the period July 1, 2001, through December 
31, 2024, shall, for the first twelve months subsequent to conversion 
categorize the telecommunications plant and expenses and develop 
separations allocation factors in accordance with the separations 
procedures in effect as of December 31, 2000. Effective July 1, 2001 
through December 31, 2024, such companies shall utilize the separations 
allocation factors and account categorization subject to the 
requirements of paragraphs (a) and (b) of this section based on the 
category relationships and allocation factors for the twelve months 
subsequent to the conversion to cost company status.

84 FR 4360, Feb. 15, 2019]



Sec.  36.4  Streamlining procedures for processing petitions for waiver
of study area boundaries.

    Effective January 1, 2012, local exchange carriers seeking a change 
in study area boundaries shall be subject to the following procedure:
    (a) Public Notice and Review Period. Upon determination by the 
Wireline Competition Bureau that a petitioner has filed a complete 
petition for study area waiver and that the petition is appropriate for 
streamlined treatment, the Wireline Competition Bureau will issue a 
public notice seeking comment on the petition. Unless otherwise notified 
by the Wireline Competition Bureau, the petitioner is permitted to alter 
its study area boundaries on the 60th day after the reply comment due 
date, but only in accordance with the boundary changes proposed in its 
application.
    (b) Comment Cycle. Comments on petitions for waiver may be filed 
during the first 30 days following public notice, and reply comments may 
be filed during the first 45 days following public notice, unless the 
public notice specifies a different pleading cycle. All comments on 
petitions for waiver shall be filed electronically, and shall satisfy 
such other filing requirements as may be specified in the public notice.

                        Central Office Equipment



Sec.  36.121  General.

    (a) The costs of central office equipment are carried in the 
following accounts:

                        Table 1 to Paragraph (a)
------------------------------------------------------------------------
 
------------------------------------------------------------------------
Central Office Switching.................  Account 2210.
Operator Systems.........................  Account 2220.
Central Office Transmission..............  Account 2230.
------------------------------------------------------------------------

    (b) Records of the cost of central office equipment are usually 
maintained

[[Page 509]]

for each study area separately by accounts. However, each account 
frequently includes equipment having more than one use. Also, equipment 
in one account frequently is associated closely with equipment in the 
same building in another account. Therefore, the separations procedures 
for central office equipment have been designed to deal with categories 
of plant rather than with equipment in an account.
    (c) In the separation of the cost of central office equipment among 
the operations, the first step is the assignment of the equipment in 
each study area to categories. The basic method of making this 
assignment is the identification of the equipment assignable to each 
category, and the determination of the cost of the identified equipment 
by analysis of accounting, engineering and other records.
    (1) The cost of common equipment not assigned to a specific 
category, e.g., common power equipment, including emergency power 
equipment, aisle lighting and framework, including distributing frames, 
is distributed among the categories in proportion to the cost of 
equipment, (excluding power equipment not dependent upon common power 
equipment) directly assigned to categories.
    (i) The cost of power equipment used by one category is assigned 
directly to that category, e.g., 130-volt power supply provided for 
circuit equipment. The cost of emergency power equipment protecting only 
power equipment used by one category is also assigned directly to that 
category.
    (ii) Where appropriate, a weighting factor is applied to the cost of 
circuit equipment in distributing the power plant costs not directly 
assigned, in order to reflect the generally greater power use per dollar 
of cost of this equipment.
    (d) The second step is the apportionment of the cost of the 
equipment in each category among the operations through the application 
of appropriate use factors or by direct assignment.

FR 63584, Dec. 11, 2018]



Sec.  36.122  Categories and apportionment procedures.

    (a) The following categories of central office equipment and 
apportionment procedures therefore are set forth in Sec. Sec.  36.123 
through 36.126.

Operator Systems Equipment.............  Category 1.
Tandem Switching Equipment.............  Category 2.
Local Switching Equipment..............  Category 3.
Circuit Equipment......................  Category 4.
 



Sec.  36.123  Operator systems equipment--Category 1.

    (a) Operator systems equipment is contained in Account 2220. It 
includes all types of manual telephone switchboards except tandem 
switchboards and those used solely for recording of calling telephone 
numbers in connection with customer dialed charge traffic. It includes 
all face equipment, terminating relay circuits of trunk and toll line 
circuits, cord circuits, cable turning sections, subscriber line 
equipment, associated toll connecting trunk equipment, number checking 
facilities, ticket distributing systems, calculagraphs, chief operator 
and other desks, operator chairs, and other such equipment.
    (1) Operator systems equipment is generally classified according to 
operating arrangements of which the following are typical:
    (i) Separate toll boards
    (ii) Separate local manual boards
    (iii) Combined local manual and toll boards
    (iv) Combined toll and DSA boards
    (v) Separate DSA and DSB boards
    (vi) Service observing boards
    (vii) Auxiliary service boards
    (viii) Traffic service positions
    (2) If switchboards as set forth in Sec.  36.123(a) are of the key 
pulsing type, the cost of the key pulsing senders, link and trunk finder 
equipment is included with the switchboards.
    (3) DSB boards include the associated DSB dial equipment, such as 
link and sender equipment.
    (4) Traffic service position systems include the common control and 
trunk equipment in addition to the associated groups of positions 
wherever located.
    (5) Effective July 1, 2001, through December 31, 2024, study areas 
subject to

[[Page 510]]

price cap regulation, pursuant to Sec.  61.41 of this chapter, shall 
assign the average balance of Account 2220, Operator Systems, to the 
categories/subcategories, as specified in paragraph (a)(1) of this 
section, based on the relative percentage assignment of the average 
balance of Account 2220 to these categories/subcategories during the 
twelve-month period ending December 31, 2000.
    (6) Effective July 1, 2001 through December 31, 2024, all study 
areas shall apportion the costs assigned to the categories/
subcategories, as specified in paragraph (a)(1) of this section, among 
the jurisdictions using the relative use measurements for the twelve-
month period ending December 31, 2000 for each of the categories/
subcategories specified in paragraphs (b) through (e) of this section.
    (b) The cost of the following operator systems equipment is 
apportioned among the operations on the basis of the relative number of 
weighted standard work seconds handled at the switchboards under 
consideration.
    (1) The following types of switchboards at toll centers are 
generally apportioned individually:
    (i) Separate toll boards. These usually include outward, through and 
inward positions in separate lines and associated inward toll 
switchboard positions in line.
    (ii) Switchboards handling both local and toll, either combined or 
having segregated local and toll positions in the same line.
    (iii) Switchboards handling both toll and DSA, either combined or 
having segregated toll and DSA positions in the same line.
    (iv) Traffic service positions, including separately located groups 
of these positions when associated with a common basic control unit.
    (2) The following types of switchboards at toll centers are 
apportioned individually, or by groups of comparable types of boards for 
each exchange:
    (i) Separate local manual boards. This includes the local positions 
of manual boards where inward toll positions are in the same line.
    (ii) Separate DSA boards.
    (iii) Separate DSB boards.
    (3) Tributary boards may be treated individually if warranted or 
they may be treated on a group basis.
    (c) Auxiliary service boards generally handle rate and route, 
information, and intercept service at individual or joint positions. The 
cost of these boards is apportioned as follows:
    (1) The cost of separate directory assistance boards is apportioned 
among the operations on the basis of the relative number of weighted 
standard work seconds handled at the boards under consideration. 
Directory assistance weighted standard work seconds are apportioned 
among the operations on the basis of the classification of these 
weighted standard work seconds as follows:
    (i) Directory assistance weighted standard work seconds first are 
classified between calls received over toll directory assistance trunks 
from operators or customers and all other directory assistance calls.
    (ii) The directory assistance weighted standard work seconds of each 
type further are classified separately among the operations on the basis 
of an analysis of a representative sample of directory assistance calls 
of each type with reference to the locations of the calling and called 
stations for each call.
    (2) The cost of separate intercept boards and automated intercept 
systems in the study area is apportioned among the operations on the 
basis of the relative number of subscriber line minutes of use.
    (3) The cost of separate rate and route boards is generally included 
with the cost of the toll boards served and is apportioned with those 
boards.
    (4) Where more than one auxiliary service is handled at an auxiliary 
board, the cost of the board is apportioned among the auxiliary services 
on the basis of the relative number of weighted standard work seconds 
for each service. The cost of that part of the board allocated to each 
auxiliary service is apportioned among the operations in the same manner 
as for a separate auxiliary board.
    (d) The cost of joint exchange and toll service observing boards is 
first apportioned between exchange and toll use on the basis of the 
relative number

[[Page 511]]

of exchange and toll service observing units at these boards. The cost 
of separate toll service observing boards and the toll portion of joint 
service observing boards is apportioned between state and interstate 
operations on the basis of the relative number of toll minutes of use 
associated with the toll messages originating in the offices observed.
    (e) Traffic Service Position System (TSPS) investments are 
apportioned as follows:
    (1) Operator position investments are apportioned on the basis of 
the relative weighted standard work seconds for the entire TSPS complex.
    (2) Remote trunk arrangement (RTA) investments are apportioned on 
the basis of the relative processor real time (i.e., actual seconds) 
required to process TSPS traffic originating from the end offices served 
by each RTA.
    (3) The remaining investments at the central control location, such 
as the stored program control and memory, is apportioned on the basis of 
the relative processor real time (i.e., actual seconds) for the entire

Sec.  36.151  General.

    (a) Cable and Wire Facilities, Account 2410, includes the following 
types of communications plant in service: Poles and antenna supporting 
structures, aerial cable, underground cable, buried cable, submarine 
cable, deep sea cable, intrabuilding network cable, aerial wire and 
conduit systems.
    (b) For separations purposes, it is necessary to analyze the cable 
and wire facilities classified in subordinate records in order to 
determine their assignment to the categories listed in the following 
paragraphs.
    (c) In the separation of the cost of cable and wire facilities among 
the operations, the first step is the assignment of the facilities to 
certain categories. The basic method of making this assignment is the 
identification of the facilities assignable to each category and the 
determination of the cost of the facilities so identified. Because of 
variations among companies in the character of the facilities and 
operating conditions, and in the accounting and engineering records 
maintained, the detailed methods followed, of necessity, will vary among 
the companies. The general principles to be followed, however, will be 
the same for all companies.
    (d) The second step is the apportionment of the cost of the 
facilities in each category among the operations through the application

    (a) C&WF are basically divided between exchange and interexchange. 
Exchange C&WF consists of the following categories:
    (1) Exchange Line C&WF Excluding Wideband--Category 1--This category 
includes C&W facilities between local central offices and subscriber 
premises used for message telephone, private line, local channels, and 
for circuits between control terminals and radio stations providing very 
high frequency maritime service or urban or highway mobile service.
    (2) Wideband and Exchange Trunk C&WF--Category 2--This category 
includes all wideband, including Exchange Line Wideband and C&WF between 
local central offices and Wideband facilities. It also includes C&WF 
between central offices or other switching points used by any common 
carrier for interlocal trunks wholly within an exchange or metropolitan 
service area, interlocal trunks with one or both terminals outside a 
metropolitan service area carrying some exchange traffic, toll 
connecting trunks, tandem trunks principally carrying exchange traffic, 
the exchange trunk portion of WATS access lines, the exchange trunk 
portion of private line local channels, and the exchange trunk portion 
of circuits between control terminals and radio stations providing very 
high frequency maritime service or urban or highway mobile service.

[[Page 518]]

    (3) The procedures for apportioning the cost of exchange cable and 
wire facilities among the operations are set forth in Sec. Sec.  36.154 
and 36.155.
    (b) Interexchange C&WF--Category 3--This category includes the C&WF 
used for message toll and toll private line services. It includes cable 
and wire facilities carrying intertoll circuits, tributary circuits, the 
interexchange channel portion of special service circuits, circuits 
between control terminals and radio stations used for overseas or 
coastal harbor service, interlocal trunks between offices in the 
different exchange or metropolitan service areas carrying only message 
toll traffic and certain tandem trunks which carry principally message 
toll traffic.
    (1) The procedures for apportioning the cost of interexchange cable 
and wire facilities among the operations are set forth in Sec.  36.156.
    (c) Host/Remote Message C&WF--Category 4--This category includes the 
cost of message host/remote location C&WF for which a message circuit 
switching function is performed at the host central office. It applies 
to C&WF between host offices and all remote locations. The procedures 
for apportioning the cost of these facilities among the operations are 
set forth in Sec.  36.157.
    (d) Effective July 1, 2001, through December 31, 2024, study areas 
subject to price cap regulation, pursuant to Sec.  61.41 of this 
chapter, shall assign the average balance of Account 2410 to the 
categories/subcategories, as specified in paragraph (a) through (c) of 
this section based on the relative percentage assignment of the average 
balance of Account 2410 to these categories/subcategories during the 
twelve-month period ending December 31, 2000.

Sec.  36.153  Assignment of Cable and Wire Facilities (C&WF) to categories.

    (a) Cable consists of: Aerial cable, underground cable, buried 
cable, submarine cable, deep sea cable and intrabuilding network cable. 
Where an entire cable or aerial wire is assignable to one category, its 
cost and quantity are, where practicable, directly assigned.
    (1) Cable. (i) There are two basic methods for assigning the cost of 
cable to the various categories. Both of them are on the basis of 
conductor cross section. The methods are as follows:
    (A) By section of cable, uniform as to makeup and relative use by 
categories. From an analysis of cable engineering and assignment 
records, determine in terms of equivalent gauge the number of pairs in 
use or reserved, for each category. The corresponding percentages of 
use, or reservation, are applied to the cost of the section of cable, 
i.e., sheath meters times unit cost per meter, to obtain the cost 
assignable to each category.
    (B) By using equivalent pair kilometers, i.e., pair kilometers 
expressed in terms of equivalent gauge. From an analysis of cable 
engineering and assignment records, determine the equivalent pair 
kilometers in use for each category by type of facility, e.g., quadded, 
paired. The equivalent pair kilometers are then divided by a cable fill 
factor to obtain the equivalent pair kilometers in plant. The total 
equivalent pair kilometers in plant assigned to each category is 
summarized by type of facility, e.g., quadded and paired, and priced at 
appropriate average unit costs per equivalent pair kilometer in plant. 
If desired, this study may be made in terms of circuit kilometers rather 
than physical pair kilometers, with average cost and fill data 
consistent with the basis of the facilities kilometer count.
    (ii) In the assignment of the cost of cable under the two basic 
methods described in Sec.  36.153(a)(1)(i) consideration is given to the 
following:
    (A) Method (A) described in Sec.  36.153(a)(1)(i)(A) will probably 
be found more desirable where there is a relatively small amount of 
cable of variable make-up and use by categories. Conversely, method (B) 
described in Sec.  36.153(a)(1)(i)(B) will probably be more desirable 
where there is a large amount of cable of variable make-up and use by 
categories. However, in some cases a combination of both methods may be 
desirable.

[[Page 519]]

    (B) It will be desirable in some cases to determine the amount 
assignable to a particular category by deducting from the total the sum 
of the amounts assigned to all other categories.
    (C) For use in the assignment of poles to categories, the equivalent 
sheath kilometers of aerial cable assigned to each category are 
determined. For convenience, these quantities are determined in 
connection with assignment of cable costs.
    (D) Where an entire cable is assignable to one category, its costs 
and quantity are, where practicable, directly assigned.
    (iii) For cables especially arranged for high-frequency transmission 
such as shielded, disc-insulated and coaxial, recognition is given to 
the additional costs which are charged to the high-frequency complement.
    (2) Cable Loading. (i) Methods for assigning the cost of loading 
coils, cases, etc., to categories are comparable with those used in 
assigning the associated cable to categories. Loading associated with 
cable which is directly assigned to a given category is also directly 
assigned. The remaining loading is assigned to categories in either of 
the following bases:
    (A) By an analysis of the use made of the loading facilities where a 
loading coil case includes coils assignable to more than one category, 
e.g., in the case of a single gauge uniformly loaded section, the 
percentage used in the related cable assignment are applicable, or
    (B) By pricing out each category by determining the pair meters of 
loaded pairs assigned to each category and multiplying by the unit cost 
per pair meter of loading by type.
    (3) Other Cable Plant. (i) In view of the small amounts involved, 
the cost of all protected terminals and gas pressure contactor terminals 
in the toll cable subaccounts is assigned to the appropriate 
Interexchange Cable & Wire Facilities categories. The cost of all other 
terminals in the exchange and toll cable subaccounts is assigned to 
Exchange Cable and Wire Facilities.
    (b) Aerial Wire. (1) The cost of wire accounted for as exchange is 
assigned to the appropriate Exchange Cable & Wire Facilities categories. 
The cost of wire accounted for as toll, which is used for exchange, is 
also assigned to the appropriate Exchange Cable & Wire Facilities 
categories. The cost of the remaining wire accounted for as toll is 
assigned to the appropriate Interexchange Cable & Wire Facilities 
categories as described in Sec.  36.156. For companies not maintaining 
exchange and toll subaccounts, it is necessary to review the plant 
records and identify wire plant by use. The cost of wire used for 
providing circuits directly assignable to a category is assigned to that 
category. The cost of wire used for providing circuit facilities jointly 
used for exchange and interexchange lines is assigned to categories on 
the basis of the relative number of circuit kilometers involved.
    (c) Poles and Antenna Supporting Structures. (1) In the assignment 
of these costs, anchors, guys, crossarms, antenna supporting structure, 
and right-of-way are included with the poles.
    (2) Poles. (i) The cost of poles is assigned to categories based on 
the ratio of the cost of poles to the total cost of aerial wire and 
aerial cable.
    (d) Conduit Systems. (1) The cost of conduit systems is assigned to 
categories on the basis of the assignment of the cost of underground 
cable.

Sec.  36.154  Exchange Line Cable and Wire Facilities (C&WF)-
-Category 1--apportionment procedures.

    (a) Exchange Line C&WF--Category 1. The first step in apportioning 
the cost of exchange line cable and wire facilities among the operations 
is the determination of an average cost per working loop. This average 
cost per working loop is determined by dividing the total cost of 
exchange line cable and wire Category 1 in the study area by the sum of 
the working loops described in subcategories listed below. The 
subcategories are:
    Subcategory 1.1--State Private Lines and State WATS Lines. This 
subcategory shall include all private lines and WATS lines carrying 
exclusively state traffic as well as private lines and WATS lines 
carrying both state and

[[Page 520]]

interstate traffic if the interstate traffic on the line involved 
constitutes ten percent or less of the total traffic on the line.
    Subcategory 1.2--Interstate private lines and interstate WATS lines. 
This subcategory shall include all private lines and WATS lines that 
carry exclusively interstate traffic as well as private lines and WATS 
lines carrying both state and interstate traffic if the interstate 
traffic on the line involved constitutes more than ten percent of the 
total traffic on the line.
    Subcategory 1.3--Subscriber or common lines that are jointly used 
for local exchange service and exchange access for state and interstate 
interexchange services.
    (b) The costs assigned to subcategories 1.1 and 1.2 shall be 
directly assigned to the appropriate jurisdiction.
    (c) Effective January 1, 1986, 25 percent of the costs assigned to 
subcategory 1.3 shall be allocated to the interstate jurisdiction.
    (d)-(f) [Reserved]
    (g) Effective July 1, 2001, through December 31, 2024, all study 
areas shall apportion Subcategory 1.3 Exchange Line C&WF among the

[83 FR 63587, Dec. 11, 2018]



Sec.  36.412  Apportionment procedures.

    (a) For apportionment purposes, the expenses in this account are 
segregated into two groups as follows: (1) Operating Federal, State and 
local income taxes and (2) all other operating taxes.
    (b) Operating Federal, State and local income taxes are apportioned 
among the operations on the basis of the approximate net taxable income 
(positive or negative) applicable to each of the operations. The 
approximate net taxable income from each of the operations is the 
summation of the following amounts apportioned to each operation by 
means of the procedures set forth in this Manual:
    (1) Operating revenues,
    (2) Less operating expenses,
    (3) Less operating taxes except the net income tax being apportioned 
and except any other tax not treated as a deductible item in the 
determination of taxable net income for this purpose.
    (4) Less operating fixed charges.
    (i) The amount of fixed charges attributable to the operations is 
obtained by subtracting the tax component (positive or negative) 
attributable to other than the operating fixed charges, i.e., fixed 
charges on non-operating investments are that proportion of total fixed 
charges which non-operating net investments are of total operating and 
non-operating net investments.
    (ii) Operating fixed charges including interest on Rural Telephone 
Bank Stock are apportioned among the operations on the basis of the 
separation of the cost of telephone plant less appropriate reserves.
    (c) Other operating taxes should be directly assigned to the 
appropriate jurisdiction where possible, e.g., Local Gross Receipts may 
be directly identified as applicable to one jurisdiction. Where direct 
assignment is not feasible, these expenses should be apportioned among 
the operations on the basis of the separation of the cost of 
Telecommunications Plant in Service--Account 2001.

                          Equal Access Expenses



Sec.  36.421  Equal access expenses.

    (a) Equal access expenses include only initial incremental pre-
subscription costs and other initial incremental expenditures related 
directly to the provision of equal access, that would not be required to 
upgrade the capabilities of the office involved absent the provision of 
equal access. Equal access expenses are limited to such expenditures for 
converting central offices that serve competitive interexchange carriers 
or where there has been a bona fide request for conversion to equal 
access.

[[Page 535]]

    (b) Equal access expenses are apportioned between the jurisdictions 
by first segregating them from all other expenses in the primary 
accounts and then allocating them on the same basis as equal access 
investment.
