[WT Docket No. 94-148, FCC 96-51]


Terrestrial Microwave Fixed Radio Services

AGENCY: Federal Communications Commission.

ACTION: Final rule.

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

SUMMARY: The Commission has adopted a Report and Order to establish 
regulations governing the Terrestrial Microwave Fixed Radio Services 
and implement section 403(j) of the Telecommunications Act of 1996. 
These amendments streamline the Commission's rules, expedite processing 
of authorizations for the Terrestrial Microwave Fixed Radio Services, 
and clarify rules concerning the Terrestrial Microwave Fixed Radio 
Services.

EFFECTIVE DATE: These regulations are effective August 1, 1996.

FOR FURTHER INFORMATION CONTACT: Robert James of the Wireless 
Telecommunications Bureau at (202) 418-0680.

SUPPLEMENTARY INFORMATION: This is a summary of the Commission's Report 
and Order, adopted February 8, 1996, and released February 29, 1996. 
The full text of this action is available for inspection and copying 
during normal business hours in the FCC Reference Center, Room 239, 
1919 M Street, NW., Washington, DC. The complete text may be purchased 
from the Commission's copy contractor, ITS, Inc., (202) 857-3800, 2100 
M Street, NW., Suite 140, Washington, DC 20037.

Summary of Report and Order

    1. In this action, the Commission created one comprehensive new 
rule part for the microwave services and eliminated undue regulatory 
burdens resulting in significant benefits for both the public and the 
Commission. We reorganized and amended parts 21 and 94 of the rules to 
establish a new part 101. We anticipate that the new consolidated part 
101 will result in a number of major benefits. First, the public will 
benefit from simplified and streamlined rules. Second, both the public 
and the Commission will benefit from reduced regulatory burdens. Third, 
the new rules will encourage more efficient use of microwave spectrum 
by permitting more intensive use of microwave equipment. Fourth, common 
technical standards for common carrier and private operational fixed 
microwave equipment will lead to economics of scale in microwave 
equipment production and lower equipment prices to licensees. The new 
consolidated part 101 will eliminate arbitrary distinction and further 
regulatory symmetry between common carrier and private operational 
fixed microwave services.
    2. Section 403(j) of the 1996 Telecommunications Act amends section 
309(b) of the Communications Act by removing the requirement that the 
Commission delay granting an application for a private fixed point-to-
point microwave station until thirty days after the Commission issues a 
public notice announcing that it has accepted the application for 
filing. This Report and Order deletes Sec. 1.962(a) of its rules, 47 
CFR 1.962(a), to reflect this statutory change.
    3. These new rules reflect a comprehensive restructuring in the 
regulatory requirements and policies of the fixed microwave services. 
The streamlined and simplified rules, reduce regulatory burdens, 
encourage more efficient use of the microwave spectrum, and foster 
economies of scale in microwave equipment production. These rules will 
allow licensees to compete more on price and quality of service rather 
than on regulatory gamesmanship.
    4. The rules are set forth below.
    5. This Report and Order is issued under the authority of sections 
4(i) and 303(r) of the Communications Act of 1934, as amended, 47 
U.S.C. 154(i) and 303(r).
    6. Need and purpose of this action. This Report and Order 
simplifies the rules for the common carrier and private operational 
fixed services, currently contained respectively in parts 21 and 94 of 
the Commission's rules, and consolidates those rules into a new part 
101. These new rules eliminate unnecessary information collection 
requirements, eliminate redundancy, remove obsolete language, and 
promote the public interest.
    7. Summary of issues raised by the public. Several commenters 
suggested modifications to some of the Commission's proposals. As a 
result of these comments, we have made modifications to the proposed 
rules as appropriate. The specific suggestions and modifications are 
discussed in the paragraphs above.
    8. Significant alternatives considered. The Notices of Proposed 
Rule Making in the two subject proceedings offered numerous proposals. 
The commenters overwhelmingly supported the majority of the proposed 
rule changes. Several commenters suggested modifications to some of the 
Commission's proposals. Many of the suggested modifications are 
incorporated in the final rules. The regulatory burdens which we have 
retained are necessary to fulfill our duties under the Communications 
Act of 1934, as amended. We will continue to examine alternatives in 
the future with the objective of eliminating unnecessary regulations 
and minimizing economic impact on small business entities.

located at fixed points. When service is provided on a common carrier 
basis, subscriber supplied information is transmitted to points 
designated by the subscriber. When service is provided on a non-common 
carrier basis, transmissions may include information originated by 
persons other than the licensee, licensee- manipulated information 
supplied by other persons, or information originated by the licensee. 
Point-to-point radio return links from a subscriber's location to a MDS 
operator's facilities may be authorized in the 18,580 through 18,820 
MHz and 18,920 through 19,160 MHz bands. Rules governing such operation

for private operational and common carrier fixed microwave operations 
that require transmitting facilities on land or in specified offshore 
coastal areas within the continental shelf.
    (b) The rules in this part are issued pursuant to the authority 
contained in

[[Page 26678]]

Titles I through III of the Communications Act of 1934, as amended, 
which vest authority in the Federal Communications Commission to 
regulate common carriers of interstate and foreign communications, to 
regulate radio transmissions and issue licenses for radio stations, and 
to regulate all interstate and foreign communications by wire and radio 
necessary to the accomplishment of the purposes of the Act.


Sec. 101.3  Definitions.

    As used in this part.
    Antenna power gain. The ratio of the maximum radiation intensity to 
that of an isotropic (omnidirectional) radiator in the far field of its 
main (forward direction) lobe.
    Antenna power input. The radio frequency peak or RMS power, as the 
case may be, supplied to the antenna from the antenna transmission line 
and its associated impedance matching network.
    Antenna structure. The antenna, its supporting structure and 
anything attached to it.
    Assigned frequency. The center of the frequency band assigned to a 
station.
    Assigned frequency bandwidth. The frequency band within which the 
emission of a station is authorized; the width of the band equals the 
necessary bandwidth plus twice the absolute value of the frequency 
tolerance.
    Authorized bandwidth. The maximum bandwidth authorized to be used 
by a station as specified in the station license. (See Sec. 2.202 of 
this chapter)
    Authorized frequency. The frequency, or frequency range, assigned

authorization.
    Authorized power. The maximum power a station is permitted to use. 
This power is specified by the Commission in the station's

    Automatic Transmitter Power Control (ATPC). ATPC is a feature of a 
digital microwave radio system that adjusts the transmitter output 
power. ATPC allows the transmitter to operate at less than maximum 
power for most of the time. In a radio employing ATPC, the transmit 
power is reduced during normal operation conditions. When the receiver 
detects a reduction in signal level, a control signal is sent to the 
far end transmitter, instructing it to increase the power output to 
compensate for the signal reduction. The power output is limited to the 
licensed (maximum) transmit power. Guidelines for use of ATPC are set 
forth in the TIA Telecommunications Systems Bulletin TSB 10, 
``Interference Criteria for Microwave Systems (TSB 10).''

to be renewed. Whenever a group of station licenses in the same radio 
service are to be renewed simultaneously, a single ``blanket'' 
application may be filed to cover the entire group if the application 
identifies each station by call sign and station location. Applicants 
should note also any special renewal requirements under the rules for 
each radio service. When a licensees submits a timely application for 
renewal of a station license, the existing license continues in effect 
until the Commission has rendered a decision on the renewal 
application.
    (d) Assignment of license. FCC Form 702 (``Application for Consent 
to Assignment of Radio Station Construction Authorization or License 
for Stations in Services Other than Broadcast'') must be submitted to 
assign voluntarily (as by, for example, contract or other agreement) or 
involuntarily (as by, for example, death, bankruptcy, or legal 
disability) the station authorization. In the case of involuntary 
assignment (or transfer of control) the application must be filed 
within 10 days of the event causing the assignment (or transfer of 
control). FCC Form 702 must also be used for non-substantial (pro 
forma) assignments. Whenever a group of station licenses in the same 
radio services are to be assigned to a single assignee, a single 
``blanket'' application may be filed to cover the entire group, if the 
application identifies each station by call sign and station location. 
Licensees who fail to consummate must modify their licenses to conform 
them to their initial state within 30 days of a failure to consummate.
    (e) Partial assignment of license. Authorization for assignment 
from one company to another of only a part or portions of the 
facilities (transmitters) authorized under an existing license (as 
distinguished from an assignment of the facilities in their entirety) 
may be granted upon application:
    (1) By the assignor on FCC Form 494 for deletion of the assigned 
facilities (no fee required); and
    (2) By the assignee on FCC Form 494 with a request for 
recertification in the name of the assignee for frequencies eliminated 
from assignor's license (fee required). In the event that consummation 
does not occur, FCC Form 494 must be submitted to return the assignor's 
license to its original condition.
    (f) Transfer of control of corporation holding a conditional 
license or license. FCC Form 704 (``Application for Consent to Transfer 
of Control'') must be submitted in order to voluntarily or 
involuntarily transfer control (de jure or de facto) of a corporation 
holding any conditional licenses or licenses. FCC Form 704 must also be 
used for non-substantial (pro forma) transfers of control. Licensees 
who fail to consummate must modify their licenses to conform them to 
their initial state within 30 days of a failure to consummate.


Sec. 101.17  [Reserved]


Sec. 101.19  General application requirements.

    (a) Each application for a license or for consent to assignment or 
transfer of control must:
    (1) Disclose fully the real party (or parties) in interest, 
including (as required) a complete disclosure of the identity and 
relationship of those persons or entities directly or indirectly owning 
or controlling (or both) the applicant;
    (2) Demonstrate the applicant's legal, technical, and other 
qualifications to be a licensee;
    (3) Submit the information required by the Commission's rules, 
requests, and application forms;
    (4) Be maintained by the applicant substantially accurate and 
complete in all significant respects in accordance with the provisions 
of Sec. 1.65 of this chapter; and
    (5) Show compliance with the special requirements applicable to 
each radio service and make all special showings that may be applicable 
(e.g., those required by Secs. 101.103(d), 101.701, and of this part, 
etc.).
    (b) In addition to the general application requirements of 
Secs. 101.19 and 101.21, applicants must submit any additional 
documents, exhibits, or signed written statements of fact:
    (1) As may be required by the other parts of the Commission's 
rules, and the other subparts of this part (particularly Subpart C and 
those subparts applicable to the specific radio service involved); and
    (2) As the Commission, at any time after the filing of an 
application and during the term of any authorization, may require from 
any applicant, permittee, or licensee to enable it to determine whether 
a radio authorization should be granted, denied, or revoked.
    (c) All applicants are required to indicate at the time their 
application is filed whether an authorization of the facilities is 
categorically excluded as defined by Sec. 1.1306 of this chapter. If 
answered affirmatively, an Environmental Assessment as described by 
Sec. 1.1311 of this chapter, need not be filed with the application.


Sec. 101.21  Technical content of applications.

    Applications must contain all technical information required by the 
application form and any additional information necessary to fully 
describe the proposed facilities and to demonstrate compliance with all 
technical requirements of the rules governing the radio service 
involved (see subparts C, F, G, I, and J, as appropriate). The 
following paragraphs describe a number of technical requirements.
    (a) Each application proposing a new or modified antenna structure 
for a station (including a receive-only or passive repeater) must 
indicate whether the owner has registered the structure with the 
Commission. Complete information as to rules concerning the 
registration, construction, marking and lighting of antenna structures 
is

[[Page 26683]]

contained in part 17 of this chapter. See also Sec. 101.121 if the 
structure is used by more than one station.
    (b) Each application for construction permit for a developmental 
authorization must be accompanied by pertinent supplemental information 
as required by Sec. 101.411 in addition to such information as may be 
specifically required by this section.
    (c) An applicant proposing construction of one or more new stations 
or modification of existing stations must submit the location and 
telephone number (if known) of the maintenance center for a fixed 
microwave system. In lieu of providing the location and telephone 
number of the maintenance center(s) on a case by case basis, a licensee 
may file a complete list for all operational stations with the 
Commission and the Engineer-In-Charge of the appropriate radio district 
on an annual basis or at more frequent intervals as necessary to keep 
the information current.
    (d) Each application in the Private Operational Fixed Point-to-
Point Microwave, Common Carrier Fixed Point-to-Point Microwave, Local 
Television Transmission, and Digital Electronic Message Services 
(excluding user stations) proposing a new or replacement antenna 
(excluding omnidirectional antennas) must include an antenna radiation 
pattern showing the antenna power gain distribution in the horizontal 
plane expressed in decibels, unless such pattern is known to be on file 
with the Commission in which case the applicant may reference in its 
application the FCC-ID number that indicates that the pattern is on 
file with the Commission.
    (e) Each application in the Private Operational Fixed Point-to-
Point Microwave Service and the Common Carrier Fixed Point-to-Point 
Microwave Service must include the following information:

Applicant's name and address.
Transmitting station name.
Transmitting station coordinates.
Frequencies and polarizations to be added, changed or deleted.
Transmitting equipment type, its stability, actual output power, 
emission designator, and type of modulation (loading).
Transmitting antenna type(s), model, gain, and, if required, a 
radiation pattern provided or certified by the manufacturer.
Transmitting antenna center line height(s) above ground level and 
ground elevation above mean sea level.
Receiving station name.
Receiving station coordinates.
Receiving antenna type(s), model, gain, and, if required, a 
radiation pattern provided or certified by the manufacturer.
Receiving antenna center line height(s) above ground level and 
ground elevation above mean sea level.
Path azimuth and distance.
Estimated transmitter transmission line loss expressed in dB.
Estimated receiver transmission line loss expressed in dB.

    Note: The position location of antenna sites shall be determined 
to an accuracy of no less than 1 second in the 
horizontal dimensions (latitude and longitude) and 1 
meter in the vertical dimension (ground elevation) with respect to 
the National Spacial Reference System.

    (f) All applicants for regular authorization must, before filing an 
application, amendments to a pending application, or modifications to a 
license, prior coordinate the proposed frequency usage with existing 
users in the area and other applicants with previously filed 
applications in accordance with the procedures in Sec. 101.103. In 
those frequency bands shared with the communication-satellite service, 
an applicant for a new station, for new points of communication, for 
the initial frequency assignment in a shared band for which 
coordination has not been previously effected, or for authority to 
modify the emission or radiation characteristics of an existing station 
in a manner that may increase the likelihood of harmful interference, 
must ascertain in advance whether the station(s) involved lie within 
the great circle coordination distance contours of an existing Earth 
station or one for which an application has been accepted for filing, 
and must coordinate his proposal with each such Earth station operator 
or applicant. For each potential interference path, the applicant must 
perform the computations required to determine that the expected level 
of interference to or from the terrestrial station does not exceed the 
maximum permissible interference power level in accordance with the 
technical standards and requirements of Secs. 25.251-25.256 of this 
chapter. 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 part 25 of this 
chapter, showing that harmful interference will not likely result from 
the proposed operation. (Technical characteristics of the Earth 
stations on file and coordination contour maps for those Earth stations 
will be kept on file for public inspection in the offices of the 
Commission's International Bureau in Washington, DC)


Sec. 101.23  Waiver of rules.

    Waivers of these rules may be granted upon application or on the 
Commission's own motion.
    A request for waiver shall contain a statement of reasons 
sufficient to justify a waiver. A waiver will not be granted except 
upon an affirmative showing that:
    (a) The underlying purpose of the rule will not be served, or would 
be frustrated, by its application in the particular case, and that 
grant of the waiver is otherwise in the public interest; or
    (b) The unique facts and circumstances of a particular case render 
application of the rule inequitable, unduly burdensome or otherwise 
contrary to the public interest. Applicants must also show the lack of 
a reasonable alternative.


Sec. 101.25  Inconsistent or conflicting applications.

    While an application is pending and undecided, no subsequent 
inconsistent or conflicting application may be filed by the same 
applicant, the applicant's successor or assignee, or on behalf or for 
the benefit of the same applicant, the applicant's successor or 
assignee.


Sec. 101.27  Repetitious applications.

    (a) Where an applicant has been afforded an opportunity for a 
hearing with respect to a particular application for a new station, or 
for an extension or enlargement of a service or facilities, and the 
Commission has, after hearing or default, denied the application or 
dismissed it with prejudice, the Commission will not consider a like 
application involving service of the same kind to the same area by the 
same applicant, or by the applicant's successor or assignee, or on 
behalf of or for the benefit of the original parties in interest, until 
after the lapse of 12 months from the effective date of the 
Commission's order. The Commission may, for good cause shown, waive the 
requirements of this section.
    (b) Where an appeal has been taken from the action of the 
Commission denying a particular application, another application for 
the same class of station and for the same area, in whole or in part, 
filed by the same applicant or by the applicant's successor or 
assignee, or on behalf or for the benefit of the original parties in 
interest, will not be considered until the final disposition of such 
appeal.


Sec. 101.29  Amendment of pending applications.

    (a) Any pending application may be amended as a matter of right if 
the

[[Page 26684]]

application has not been designated for hearing, or for comparative 
evaluation pursuant to Sec. 101.51, or for the random selection 
process, provided, however, that the amendments must comply with the 
provisions of Sec. 101.41 as appropriate.
    (b) Requests to amend an application designated for hearing or for 
comparative evaluation, or tentatively selected by the random selection 
process may be granted only if a written petition demonstrating good 
cause is submitted and properly served upon the parties of record.
    (c) The Commission will classify amendments on a case-by-case 
basis. Whenever previous amendments have been filed, the most recent 
amendment will be classified by reference to how the information in 
question stood as of the latest Public Notice issued which concerned 
the application. An amendment will be deemed to be a major amendment 
subject to Sec. 101.37 and Sec. 101.45 under any of the following 
circumstances:
    (1) If the amendment results in a substantial modification of the 
engineering proposal such as (but not necessarily limited to):
    (i) A change in, or an addition of a radio frequency channel;
    (ii) A change in polarization of the transmitted signal;
    (iii) An increase in the equivalent isotropically radiated power of 
three (3) dB or more;
    (iv) A change in type of transmitter emission or an increase in 
emission bandwidth of more than ten (10) percent;
    (v) A change in the geographic coordinates of a station's 
transmitting antenna of more than five (5) seconds of latitude or 
longitude, or both;
    (vi) A change of more than one (1) degree in the azimuth of the 
center of the main lobe of radiation of a point-to-point station's 
transmitting antenna (including any deflections by repeating devices);
    (vii) Any change which increases the antenna center line height by 
3.0 meters (ten (10) feet) or more;
    (viii) Any changes or combination of changes which would cause 
harmful electrical interference to an authorized facility or result in 
a mutually exclusive conflict with another pending application; or
    (ix) Any technical change that would increase the effective 
radiated power in any direction by more than one and one-half (1.5) dB 
in the Digital Electronic Message Service.
    (2) If the amendment would convert a proposal, such that it may 
have a significant impact upon the environment under Sec. 1.1307 of 
this chapter, which would require the submission of an environmental 
assessment, see Sec. 1.1311 of this chapter, and Commission 
environmental review, see Secs. 1.1308 and 1.1312 of this chapter.
    (3) If the amendment results in a substantial and material 
alteration of the proposed service.
    (4) If the amendment specifies a substantial change in beneficial 
ownership or control (de jure or de facto) of an applicant such that 
the change would require, in the case of an authorized station, the 
filing of a prior assignment or transfer of control application under 
section 310(d) of the Communications Act of 1934 (47 U.S.C. 310(d)). 
Such a change would not be considered major where the assignment or 
transfer of control is for legitimate business purposes other than the 
acquisition of applications.
    (5) If the amendment, or the cumulative effect of the amendment, is 
determined by the Commission otherwise to be substantial pursuant to 
section 309 of the Communications Act of 1934.
    (d) A pending application may be amended by a major amendment to 
reflect the relocation of a proposed station site and a new application 
will not be required if:
    (1) The geographic coordinates of the new station site are within 
32.2 kilometers of the coordinates of the original site; and
    (2) The relocated station would serve essentially the same purpose 
in the system as originally proposed.
    (e) The applicant must serve copies of any amendments or other 
written communications upon the following parties:
    (1) Any applicant whose application appears on its face to be 
mutually exclusive with the application being amended, including those 
applicants originally served under Sec. 101.509;
    (2) Any applicant whose application has been found by the 
Commission, as published in a public notice, to be mutually exclusive 
with the application being amended; and
    (3) Any party who has filed a petition to deny the application or 
other formal objection, when that petition or formal objection has not 
been resolved by the Commission.
    (f) The Commission may waive the service requirements of paragraph 
(e) of this section and prescribe such alternative procedures as may be 
appropriate under the circumstances to protect petitioners' interests 
and to avoid undue delay in a proceeding, if an applicant submits a 
request for waiver which demonstrates that the service requirement is 
unreasonably burdensome. Requests for waiver must be served on 
petitioners. Oppositions to the petition may be filed within five (5) 
days after the petition is filed and must be served on the applicant. 
Replies to oppositions will not be entertained.
    (g) Any amendment to an application must be signed and must be 
submitted in the same manner, and with the same number of copies, as 
was the original application. Amendments may be made in letter form if 
they comply in all other respects with the requirements of this 
chapter.


Sec. 101.31  Special temporary, temporary, and conditional 
authorizations.

    (a) Special temporary authorization. (1) In circumstances requiring 
immediate or temporary use of facilities, licensees subject to this 
part may request special temporary authority to install and/or operate 
new or modified equipment. Any such request may be submitted as an 
informal application in the manner set forth in Sec. 101.9 and must 
contain full particulars as to the proposed operation including all 
facts sufficient to justify the temporary authority sought and the 
public interest therein. No such request will be considered unless the 
request is received by the Commission at least 10 days prior to the 
date of proposed construction or operation or, where an extension is 
sought, expiration date of the existing temporary authorization.
    (2) Special temporary authorization may be granted upon written 
request in the following circumstances:
    (i) In emergency situations;
    (ii) To permit restoration or relocation of existing facilities to 
continue communication service;
    (iii) To conduct tests to determine necessary data for the 
preparation of an application for regular authorization;
    (iv) For a temporary, non-recurring service where a regular 
authorization is not appropriate;
    (v) In other situations involving circumstances which are of such 
extraordinary nature that delay in the institution of temporary 
operation would seriously prejudice the public interest.
    (3) The Commission may grant requests for special temporary 
authority without issuing the public notice provided for in Sec. 101.37 
for periods not exceeding 180 days, if there are extraordinary 
circumstances supporting the request and where delay in commencing 
temporary operation would seriously prejudice the public interest. 
Requests for special temporary authorization not involving 
extraordinary circumstances may be

[[Page 26685]]

granted without public notice for a period of 30 days where an 
application for regular operation is not contemplated or for 60 days 
pending or after the filing of an application for regular operation. 
Requests for special temporary authority are issued on a strictly 
secondary, non-interfering basis, and do not in any way affect the 
final disposition of any application or action pending before the 
Commission.
    (4) Extension of a special temporary authorization for a period of 
180 days may be granted, but the renewing applicant bears a heavy 
burden to show that extraordinary circumstances warrant such an 
extension.
    (5) Request for special temporary authorization must contain the 
following information:
    (i) Name, address, and citizenship status of the applicant;
    (ii) Need for special action, including a description of any 
emergency or damage to equipment;
    (iii) Type of operation to be conducted;
    (iv) Purpose of operation;
    (v) Time and date of operation desired;
    (vi) Class of station and nature of service;
    (vii) Location of station and points with which station will 
communicate;
    (viii) Equipment to be used, specifying manufacturer, model number, 
and number of units;
    (ix) Frequency(s) desired;
    (x) Azimuth and beamwidth of major lobe of transmitting antenna and 
ERP;
    (xi) Type of emission;
    (xii) Description of antenna to be used, including height; and
    (xiii) Certification that prior coordination is complete.
    (6) In cases of emergency found by the Commission, involving danger 
to life or property or due to damage of equipment, or during a national 
emergency proclaimed by the President or declared by the Congress or 
during the continuance of any war in which the United States is engaged 
and when such action is necessary for the national defense or safety or 
otherwise in furtherance of the war effort, or in cases of emergency 
where the Commission finds that it would not be feasible to secure 
renewal applications from existing licensees or otherwise to follow 
normal licensing procedure, the Commission will grant construction 
permits and station licenses, or modifications or renewals thereof, 
during the emergency found by the Commission or during the continuance 
of any such national emergency or war, as special temporary licenses, 
only for the period of emergency or war, requiring such action, without 
the filing of formal applications.
    (b) Temporary authorizations. (1) Authorizations may be issued upon 
proper application for rendition of temporary service to subscribers 
under the following conditions:
    (i) When a fixed station, authorized to operate at temporary 
locations, is to remain at a single location for more than 6 months, an 
application (FCC Form 402 or 494, as appropriate) for a station 
authorization designating that single location as the permanent 
location shall be filed at least 90 days prior to the expiration of the 
6-month period;
    (ii) The station shall be used only for rendition of communication 
service at a remote point where the provision of wire facilities is not 
practicable within the required time frame; and
    (iii) The antenna structure height employed at any location shall 
not exceed the criteria set forth in Sec. 17.7 of this chapter unless, 
in each instance, authorization for use of a specific maximum antenna 
structure height for each location has been obtained from the 
Commission prior to erection of the antenna. See Sec. 101.125.
    (2) Applications for authorizations to operate stations at 
temporary locations under the provisions of this section shall be made 
upon FCC Form 402 or 494, as appropriate. Blanket applications may be 
submitted for the required number of transmitters.
    (3) The licensee of stations which are authorized pursuant to the 
provisions of paragraph (b) of this section shall notify the Commission 
at least five (5) days prior to installation of the facilities, 
stating:
    (i) The call sign, manufacturer's name, type or model number, 
output power and specific location of the transmitter(s);
    (ii) The maintenance location for the transmitter;
    (iii) The location of the transmitting or receiving station with 
which it will communicate and the identity of the correspondent 
operating such facilities;
    (iv) The exact frequency or frequencies to be used;
    (v) The public interest, convenience and necessity to be served by 
operation of the proposed installation;
    (vi) The commencement and anticipated termination dates of 
operation from each location. In the event the actual termination date 
differs from the previous notification, written notice thereof promptly 
shall be given to the Commission;
    (vii) A notification shall include compliance with the provisions 
of
    Sec. 101.21(e) when operations are to be conducted in the area of 
other terrestrial microwave stations and with the provisions of 
Sec. 101.21(e) when operations are to be conducted within the 
coordination distance contours of a fixed earth station; and
    (viii) Where the notification contemplates initially a service 
which is to be rendered for a period longer than 90 days, the 
notification shall contain a showing as to why application should not 
be made for regular authorization.
    (4) Less than 5 days advance notice may be given when circumstances 
require shorter notice provided such notice is promptly given and the 
reasons in support of such shorter notice are stated.
    (5) A copy of the notification shall be kept with the station 
license.
    (c) Prior coordination. Stations authorized under this section may 
complete the prior coordination process orally and the period allowed 
for response to a coordination notification may be less than 30 days if 
the parties agree. The requirements under Sec. 101.103(d)(2)(i) for 
written documentation shall apply to such oral notice.
    (d) Certification. Any applicant under this section must submit a 
certification that neither the applicant nor any party to the applicant 
is subject to a denial of Federal benefits pursuant to section 5301 of 
the Anti-Drug Abuse Act of 1988, as required by Sec. 1.2002 of this 
chapter.
    (e) Conditional authorization. (1) An applicant for a new point-to-
point microwave radio station(s) or a modification of an existing 
station(s) in the 3,700-4,200; 5,925-6,425; 6,525-6,875; 10,550-10,680; 
10,700-11,700; 11,700-12,200; 12,200-12,700; 12,700-13,200; 13,200-
13,250; 17,700-19,700; and 21,200-23,600 MHz bands (see Sec. 101.147 
for specific service usage) may operate the proposed station(s) during 
the pendency of its applications(s) upon the filing of a properly 
completed formal application(s) that complies with subpart B of part 
101 if the applicant certifies that the following conditions are 
satisfied:
    (i) The frequency coordination procedures of Sec. 101.103 have been 
successfully completed;
    (ii) The antenna structure(s) 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

[[Page 26686]]

by the Federal Aviation Administration and cleared by the FCC;
    (iii) The grant of the application(s) does not require a waiver of 
the Commission's rules:
    (iv) The applicant has determined that the facility(ies) will not 
significantly affect the environment as defined in Sec. 1.1307 of this 
chapter;
    (v) The station site(s) does not lie within 56.3 kilometers of any 
international border or within a radio ``Quiet Zone'' identified in 
Sec. 101.123, or if operated on frequencies in the 17,700-19,700 MHz 
band, the station site(s) does not lie within the states of Colorado, 
Maryland and Virginia and the District of Columbia;
    (vi) The filed application(s) does not propose to operate in the 
10.6-10.68 GHz band, or in the 21.2-23.6 GHz band with an E.R.P. 
greater than 55 dBm pursuant to Sec. 101.147(s); and
    (vii) The filed application(s) is consistent with the proposal that 
was coordinated pursuant to Sec. 101.103.
    (2) Conditional authority ceases immediately if the application(s) 
is returned by the Commission because it is not acceptable for filing.
    (3) A conditional authorization pursuant to paragraphs (e)(1) and 
(e)(2) of this section is evidenced by retaining the original executed 
conditional licensing Certification Form with the station records. 
Conditional authorization does not prejudice any action the Commission 
may take on the subject application(s). 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).
    (4) The Certification Form, or a copy thereof, must be posted at 
each station operating pursuant to this section consistent with 
Sec. 101.215.


Sec. 101.33  Who may sign applications.

    See part 1 of this chapter (Secs. 1.743 and 1.913), for practices 
and procedures governing signatures on applications, amendments and 
related statements of fact.

Processing of Applications


Sec. 101.35  Preliminary processing of applications.

    (a) Applications received for filing are given a file number. The 
assignment of a file number to an application is for administrative 
convenience and does not indicate the acceptance of the application for 
filing and processing and does not preclude the subsequent return of 
the application.
    (b) Applications that are incomplete with respect to answers, 
supplementary statements, execution, or other matters of a formal 
character will be considered defective and may be returned to the 
applicant with a brief statement as to such defects. If an applicant is 
requested by the Commission to file any additional documents or 
information not included in the prescribed application form, failure to 
comply with such request will be deemed to render the application 
defective, and such application may be dismissed. Applications will 
also be deemed to be defective and may be returned to the applicant in 
the following cases:
    (1) Statutory disqualification of applicant;
    (2) Proposed use or purpose of station would be unlawful;
    (3) Requested frequency is not allocated for assignment for the 
service proposed;
    (4) The submitted filing fee (if required) is insufficient;
    (5) The application does not demonstrate compliance with the 
special requirements applicable to the radio service involved;
    (6) The applications does not include all necessary exhibits; or
    (7) The application fails to meet any other Commission 
requirements.
    (c) Any application that has been returned to the applicant for 
correction will be processed in original order of receipt when 
resubmitted if it is received within 60 days from the date on which it 
was returned to the applicant and the change does not involve a major 
amendment. If the application is not resubmitted within the prescribed 
time, it will be treated as a new application and considered at the 
time other applications received on the same date are considered.
    (d) Applications considered defective under paragraph (b) 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; or
    (2) The Commission, upon its own motion, waives (or allows an 
exception to), in whole or in part, any rule, regulation or 
requirement.


Sec. 101.37  Public notice period.

    (a) At regular intervals, the Commission will issue a public notice 
listing:
    (1) The acceptance for filing of common carrier applications and 
major amendments thereto;
    (2) Significant Commission actions concerning these applications;
    (3) The receipt of common carrier applications for minor 
modifications made pursuant to Sec. 101.59;
    (4) Information which the Commission in its discretion believes of 
public significance; and
    (5) Special environmental considerations as required by part 1 of 
this chapter.
    (b) A public notice will not normally be issued for any of the 
following applications:
    (1) For authorization of a minor technical change in the facilities 
of a proposed or authorized station where such a change would not be 
classified as a major amendment to a pending application, as defined by 
Sec. 101.29, or as a minor modification to a license pursuant to 
Sec. 101.59;
    (2) For temporary authorization pursuant to Sec. 101.31;
    (3) For an authorization under any of the proviso clauses of 
section 308(a) of the Communications Act of 1934 (47 U.S.C. 308(a));
    (4) For consent to an involuntary assignment or transfer of control 
of a radio authorization; or
    (5) For consent to a voluntary assignment or transfer of control of 
a radio authorization, where the assignment or transfer does not 
involve a substantial change in ownership or control.
    (c) Except as otherwise provided in this part (e.g., Sec. 101.59), 
no application that has appeared on public notice will be granted until 
the expiration of a period of thirty days following the issuance of the 
public notice listing the application, or any major amendment thereto, 
or until the expiration of a period of thirty days following the 
issuance of a public notice identifying the tentative selectee of a 
random selection process, whichever is later.
    (d) The listing of an application on public notice as accepted for 
filing does not indicate that the application has been found by the 
Commission to be acceptable for filing and does not preclude the 
subsequent return of the application.


Sec. 101.39  Dismissal and return of applications.

    (a) Except as provided under paragraph (c) of this section and 
under Sec. 101.41, any application may, upon written request, be 
dismissed without prejudice as a matter of right prior to the adoption 
date of any final Commission action or the application's designation 
for hearing or comparative evaluation.

[[Page 26687]]

    (b) A request to dismiss an application without prejudice will be 
considered after designation for hearing, after selection through the 
comparative evaluation procedure of Sec. 101.51, or after selection as 
a tentative selectee in a random selection proceeding, only if:
    (1) A written petition is submitted to the Commission and, in the 
case of applications designated for hearing or comparative evaluation, 
is properly served upon all parties of record;
    (2) The petition is submitted before the issuance date of a public 
notice of Commission action denying the application; and
    (3) The petition complies with the provision of Sec. 101.41 
(whenever applicable) and demonstrates good cause.
    (c) Except as provided under Sec. 101.41, an application designated 
for inclusion in the random selection process may be dismissed without 
prejudice as a matter of right if the applicant requests its dismissal 
at least 2 days prior to a random selection proceeding.
    (d) Dismissal for failure to prosecute or for failure to respond to 
official correspondence or requests for additional information within a 
specified time period will be without prejudice prior to its 
designation for hearing, or tentative selection by the random selection 
process. Dismissal may be with prejudice after selection of the 
comparative evaluation process, or after selection as a tentative 
selectee in a random selection proceeding.


Sec. 101.41  Ownership changes and agreements to amend or dismiss 
applications or pleadings.

    (a) Except as provided in paragraph (b) of this section, applicants 
or any other parties in interest to pending applications must comply 
with the provisions of this section whenever:
    (1) They participate in any agreement (or understanding) which 
involves any consideration promised or received, directly or 
indirectly, including any agreement (or understanding) for merger of 
interests or the reciprocal withdrawal of applications; and
    (2) The agreement (or understanding) may result in either:
    (i) A proposed substantial change in beneficial ownership or 
control (dejure or de facto) of an applicant such that the change would 
require, in the case of an authorized station, the filing of a prior 
assignment or transfer of control application under section 310(d) of 
the Communications Act of 1934 (47 U.S.C. 310(d)), or
    (ii) Proposed withdrawal, amendment or dismissal of any 
application(s), amendment(s), petition(s), pleading(s), or any 
combination thereof, which would thereby permit the grant without 
hearing, comparative evaluation under Sec. 101.51, or random selection 
of an application previously in contested status.
    (b) The provisions of this section will not be applicable to any 
engineering agreement (or understanding) that:
    (1) Resolves frequency conflicts with authorized stations or other 
pending applications without the creation of new or increased frequency 
conflicts; and
    (2) Does not involve any consideration promised or received, 
directly or indirectly (including any merger of interests or reciprocal 
withdrawal of applications), other than the mutual benefit of resolving 
the engineering conflict.
    (c) For any agreement subject to this section, the applicant of an 
application which would remain pending pursuant to such an agreement 
will be considered responsible for the compliance by all parties with 
the procedures of this section. Failure of the parties to comply with 
the procedures of this section will constitute a defect in those 
applications which are involved in the agreement and remain in a 
pending status.
    (d) The principals to any agreement or understanding subject to 
this section must comply with the standards of paragraph (e) of this 
section in accordance with the following procedure:
    (1) Within ten (10) days after entering into the agreement, the 
parties thereto must jointly notify the Commission in writing of the 
existence and general terms of such agreement, the identity of all of 
the participants and the applications involved;
    (2) Within thirty (30) days after entering into the agreement, the 
parties thereto must file any proposed application amendments, motions, 
or requests together with a copy of the agreement which clearly sets 
forth all terms and provisions, and such other facts and information as 
necessary to satisfy the standards of paragraph (e) of this section. 
Such submission must be accompanied by the certification by affidavit 
of each principal to the agreement declaring that the statements made 
are true, complete, and correct to the best of their knowledge and 
belief, and are made in good faith; and
    (3) The Commission may request any further information which in its 
judgment it believes is necessary for a determination under paragraph 
(e) of this section.
    (e) The Commission will grant an application (or applications) 
involved in the agreement (or understanding) only if it finds upon 
examination of the information submitted, and upon consideration of 
such other matters as may be officially noticed, that the agreement is 
consistent with the public interest, and the amount of any monetary 
consideration and the cash value of any other consideration promised or 
received is not in excess of those legitimate and prudent costs 
directly assignable to the engineering, preparation, filing and 
advocacy of the withdrawn, dismissed, or amended application(s), 
amendment(s), petition(s), pleading(s), or any combination thereof. 
Where such costs represent the applicant's in-house efforts, these 
costs may include only directly assignable costs and must exclude 
general overhead expenses. (The treatment to be accorded such 
consideration for interstate rate making purposes will be determined at 
such time as the question may arise in an appropriate rate proceeding.) 
An itemized accounting must be submitted to support the amount of 
consideration involved except where such consideration (including the 
fair market value of any non-cash consideration) promised or received 
does not exceed one thousand dollars ($1,000.00). Where consideration 
involves a sale of facilities or merger of interests, the accounting 
must clearly identify that portion of the consideration allocated for 
such facilities or interests and a detailed description thereof, 
including estimated fair market value. The Commission will not presume 
an agreement (or understanding) to be prima facie contrary to the 
public interest solely because it incorporates a mutual agreement to 
withdraw pending application(s), amendment(s), petition(s), 
pleading(s), or any combination thereof.


Sec. 101.43  Opposition to applications.

    (a) Any party in interest may file with the Commission a petition 
to deny any application for which public notice is required. All such 
petitions must:
    (1) Identify the application or applications including applicant's 
name, station location, Commission file numbers and radio service 
involved with which it is concerned;
    (2) Be filed in accordance with the pleading limitations, filing 
periods, and other applicable provisions of this part and part 1 of 
this chapter;
    (3) Contain specific allegations of fact (except for those of which 
official notice may be taken), supported by affidavit of a person or 
persons with personal knowledge thereof and be sufficient to make a 
prima facie showing that the petitioner is a party in interest and that 
a grant of the application would be

[[Page 26688]]

inconsistent with the public interest, convenience and necessity;
    (4) Be filed within thirty (30) days after the date of public 
notice announcing the acceptance for filing of such applications or 
major amendments thereto, or, identifying the tentative selectee of a 
random selection proceeding (unless the Commission otherwise extends 
the deadline); and
    (5) Contain a certificate of service showing that the applicant has 
been mailed a copy of the petition no later than the date on which the 
petition is filed with the Commission.
    (b) The applicant may file an opposition to any petition to deny 
and the petitioner may file a reply thereto in which allegations of 
fact or denials thereof must be supported by an affidavit of a person 
or persons with personal knowledge thereof and be clearly identified. 
The applicant must serve a copy of the opposition on the petitioner, 
and the petitioner must serve a copy of its reply on the applicant. The 
time for filing such oppositions and replies are provided in Sec. 1.45 
of this chapter.
    (c) Notwithstanding the provisions of paragraph (a) of this 
section, before Commission action on any application for an instrument 
of authorization, any person may file informal objections to the grant. 
The Commission will consider informal objections, but not necessarily 
discuss them in a written opinion, if the objection is filed at least 
one day prior to action on the application and the objection is signed 
by the submitting person with a disclosure of that person's interest. 
Such objections may be submitted in letter form. The limitation on 
pleadings and time for filing pleadings provided for in Sec. 1.45 of 
this chapter will not be applicable to any objections duly filed 
pursuant to this paragraph.
    (d) Petitions to deny not filed in accordance with paragraph (a) of 
this section will be treated as informal objections.


Sec. 101.45  Mutually exclusive applications.

    (a) The Commission will consider applications to be mutually 
exclusive if their conflicts are such that the grant of one application 
would effectively preclude by reason of harmful electrical 
interference, or other practical reason, the grant of one or more of 
the other applications. The Commission will presume ``harmful 
electrical interference'' exists when the levels of Sec. 101.105 are 
exceeded, or when there is a material impairment to service rendered to 
the public despite full cooperation in good faith by all applicants or 
parties to achieve reasonable technical adjustments which would avoid 
electrical conflict.
    (b) A common carrier application will be entitled to be included in 
a random selection process or to comparative consideration with one or 
more conflicting applications only if:
    (1) The application is mutually exclusive with the other 
application; and
    (2) The application is received by the Commission in a condition 
acceptable for filing by whichever ``cut-off'' date is earlier:
    (i) Sixty (60) days after the date of the public notice listing the 
first of the conflicting applications as accepted for filing; or
    (ii) One (1) business day preceding the day on which the Commission 
takes final action on the previously filed application (should the 
Commission act upon such application in the interval between thirty 
(30) and sixty (60) days after the date of its public notice).
    (c) Whenever three or more applications are mutually exclusive, but 
not uniformly so, the earliest filed application established the date 
prescribed in paragraph (b)(2) of this section, regardless of whether 
or not subsequently filed applications are directly mutually exclusive 
with the first filed application. (For example, applications A, B, and 
C are filed in that order. A and B are directly mutually exclusive, B 
and C are directly mutually exclusive. In order to be considered 
comparatively with B, C must be filed within the ``cut-off'' period 
established by A even though C is not directly mutually exclusive with 
A.)
    (d) Private operational fixed point-to-point microwave applications 
for authorization under this part will be entitled to be included in a 
random selection process or to comparative consideration with one or 
more conflicting applications in accordance with the provisions of 
Sec. 1.227(b)(4) of this chapter.
    (e) An application otherwise mutually exclusive with one or more 
previously filed applications, but filed after the appropriate date 
prescribed in paragraphs (b) or (d) of this section, will be returned 
without prejudice and will be eligible for refiling only after final 
action is taken by the Commission with respect to the previously filed 
application (or applications).
    (f) For the purposes of this section, any application (whether 
mutually exclusive or not) will be considered to be a newly filed 
application if it is amended by a major amendment (as defined by 
Sec. 101.29), except under any of the following circumstances:
    (1) The application has been designated for comparative hearing, or 
for comparative evaluation (pursuant to Sec. 101.51), and the 
Commission or the presiding officer accepts the amendment pursuant to 
Sec. 101.29(b);
    (2) The amendment resolves frequency conflicts with authorized 
stations or other pending applications which would otherwise require 
resolution by hearing, by comparative evaluation pursuant to 
Sec. 101.51, or by random selection pursuant to Sec. 101.49 provided 
that the amendment does not create new or additional frequency 
conflicts;
    (3) The amendment reflects only a change in ownership or control 
found by the Commission to be in the public interest, and for which a 
requested exemption from the ``cut-off'' requirements of this section 
is granted;
    (4) The amendment reflects only a change in ownership or control 
which results from an agreement under Sec. 101.41 whereby two or more 
applicants entitled to comparative consideration of their applications 
join in one (or more) of the existing applications and request 
dismissal of their other application (or applications) to avoid the 
delay and cost of comparative consideration;
    (5) The amendment corrects typographical, transcription, or similar 
clerical errors which are clearly demonstrated to be mistakes by 
reference to other parts of the application, and whose discovery does 
not create new or increased frequency conflicts; or
    (6) The amendment does not create new or increased frequency 
conflicts, and is demonstrably necessitated by events which the 
applicant could not have reasonably foreseen at the time of filing, 
such as, for example:
    (i) The loss of a transmitter or receiver site by condemnation, 
natural causes, or loss of lease or option;
    (ii) Obstruction of a proposed transmission path caused by the 
erection of a new building or other structure; or
    (iii) The discontinuance or substantial technological obsolescence 
of specified equipment, whenever the application has been pending 
before the Commission for two or more years from the date of its 
filing.
    (g) Applicants for the 932.5-935/941.5-944 MHz bands shall select a 
frequency pair. Applicants for these bands may select an unpaired 
frequency only upon a showing that spectrum efficiency will not be 
impaired and that unpaired spectrum is not available in other bands. 
During the initial filing window, frequency coordination is not

[[Page 26689]]

required, except that an application for a frequency in the 942-944 MHz 
band must be coordinated to ensure that it does not affect an existing 
broadcast auxiliary service licensee. After the initial filing window, 
an applicant must submit evidence that frequency coordination has been 
performed with all licensees affected by the application. All frequency 
coordination must be performed in accordance with Sec. 101.103. In the 
event of mutually exclusive applications occurring during the initial 
filing window for the 932.5-935/941.5-944 MHz bands, applicants shall 
be given the opportunity to resolve these situations by applying for an 
alternative frequency pair, if one is available. To the extent that 
there are no other available frequencies or to the extent that mutually 
exclusive applications remain after this process is concluded, 
lotteries shall be conducted for each frequency pair among all 
remaining mutually exclusive applications, assuming appropriate 
coordination with existing broadcast auxiliary stations can be 
concluded, where necessary. In the event of mutually exclusive 
applications being received for these bands on the same day after the 
initial filing window has closed and a subsequent filing window opened, 
lotteries shall be conducted for each frequency pair among all mutually 
exclusive applications.


Sec. 101.47  Consideration of applications.

    (a) Applications for an instrument of authorization will be granted 
if, upon examination of the application and upon consideration of such 
other matters as it may officially notice, the Commission finds that 
the grant will serve the public interest, convenience, and necessity.
    (b) The grant will be without a formal hearing if, upon 
consideration of the application, any pleadings of objections filed, or 
other matters which may be officially noticed, the Commission finds 
that:
    (1) The application is acceptable for filing, and is in accordance 
with the Commission's rules, regulations, and other requirements;
    (2) The application is not subject to comparative consideration 
(pursuant to Sec. 101.45) with another application (or applications), 
except where the competing applicants have chosen the comparative 
evaluation procedure of Sec. 101.51 and a grant is appropriate under 
that procedure;
    (3) A grant of the application would not cause harmful electrical 
interference to an authorized station;
    (4) There are no substantial and material questions of fact 
presented; and
    (5) The applicant is legally, technically, financially and 
otherwise qualified, and a grant of the application would serve the 
public interest.
    (c) Whenever the Commission, without a formal hearing, grants any 
application in part, or subject to any terms or conditions other than 
those normally applied to applications of the same type, it will inform 
the applicant of the reasons therefor, and the grant will be considered 
final unless the Commission revises its action (either by granting the 
application as originally requested, or by designating the application 
for a formal evidentiary hearing) in response to a petition for 
reconsideration that:
    (1) Is filed by the applicant within thirty (30) days from the date 
of the letter or order giving the reasons for the partial or 
conditioned grant;
    (2) Rejects the grant as made and explains the reasons why the 
application should be granted as originally requested; and
    (3) Returns the instrument of authorization.
    (d) The Commission will designate an application for a formal 
hearing, specifying with particularity the matters and things in issue, 
if, upon consideration of the application, any pleadings or objections 
filed, or other matters which may be officially noticed, the Commission 
determines that:
    (1) A substantial and material question of fact is presented;
    (2) The Commission is unable for any reason to make the findings 
specified in paragraph (a) of this section and the application is 
acceptable for filing, complete, and in accordance with the 
Commission's rules, regulations, and other requirements;
    (3) The application is entitled to comparative consideration (under 
Sec. 101.45) with another application (or applications); or
    (4) The application is entitled to comparative consideration 
(pursuant to Sec. 101.45) and the applicants have chosen the 
comparative evaluation procedure of Sec. 101.51 but the Commission 
deems such procedure to be inappropriate.
    (e) The Commission may grant, deny, or take other action with 
respect to an application designated for a formal hearing pursuant to 
paragraph (d) of this section or part 1 of this chapter.
    (f) Whenever the public interest would be served thereby the 
Commission may grant one or more mutually exclusive applications 
expressly conditioned upon final action on the applications, and then 
either conduct a random section process (in specified services under 
this rules part), designate all of the mutually exclusive applications 
for a formal evidentiary hearing or (whenever so requested) follow the 
comparative evaluation procedures of Sec. 101.51, as appropriate, if it 
appears:
    (1) That some or all of the applications were not filed in good 
faith, but were filed for the purpose of delaying or hindering the 
grant of another application;
    (2) That the public interest requires the prompt establishment of 
radio service in a particular community or area;
    (3) That a delay in making a grant to any applicant until after the 
conclusion of a hearing or a random selection proceeding on all 
applications might jeopardize the rights of the United States under the 
provision of an international agreement to the use of the frequency in 
question; or
    (4) That a grant of one application would be in the public interest 
in that it appears from an examination of the remaining applications 
that they cannot be granted because they are in violation of provisions 
of the Communications Act, other statutes, or of the provisions of this 
chapter.
    (g) Reconsideration or review of any final action taken by the 
Commission will be in accordance with subpart A of part 1 of this 
chapter.


Sec. 101.49  Grants by random selection.

    (a) If an application for an authorization in the Digital 
Electronic Message Service (DEMS) is mutually exclusive with another 
such application and satisfies the requirements of Sec. 101.45, the 
applicant may be included in the random selection process set forth in 
Secs. 1.821, 1.822 and 1.825 of this chapter.
    (b) Renewal applications will not be included in a random selection 
process.


Sec. 101.51  Comparative evaluation of mutually exclusive applications.

    (a) In order to expedite action on mutually exclusive applications 
in services under this rules part where the random selection process 
does not apply, the applicants may request the Commission to consider 
their applications without a formal hearing in accordance with the 
summary procedure outlined in paragraph (b) in this section if:
    (1) The applications are entitled to comparative consideration 
pursuant to Sec. 101.45;
    (2) The applications have not been designated for formal 
evidentiary hearing; and
    (3) The Commission determines, initially or at any time during the

[[Page 26690]]

procedure outlined in paragraph (b) of this section, that such 
procedure is appropriate, and that, from the information submitted and 
consideration of such other matters as may be officially noticed, there 
are no substantial and material questions of fact presented (other than 
those relating to the comparative merits of the applications) which 
would preclude a grant under paragraphs (a) and (b) of Sec. 101.47.
    (b) Provided that the conditions of paragraph (a) of this section 
are satisfied, applicants may request the Commission to act upon their 
mutually exclusive applications without a formal hearing pursuant to 
the summary procedure outlined below:
    (1) To initiate the procedure, each applicant will submit to the 
Commission a written statement containing:
    (i) A waiver of the applicant's right to a formal hearing;
    (ii) A request and agreement that, in order to avoid the delay and 
expense of a comparative formal hearing, the Commission should exercise 
its judgment to select from among the mutually exclusive applications 
that proposal (or proposals) which would best serve the public 
interest; and
    (iii) The signature of a principal (and the principal's attorney if 
represented).
    (2) After receipt of the written requests of all of the applicants 
the Commission (if it deems this procedure appropriate) will issue a 
notice designating the comparative criteria upon which the applications 
are to be evaluated and will request each applicant to submit, within a 
specified period of time, additional information concerning the 
applicant's proposal relative to the comparative criteria.
    (3) Within thirty (30) days following the due date for filing this 
information, the Commission will accept concise and factual argument on 
the competing proposals from the rival applicants, potential customers, 
and other knowledgeable parties in interest.
    (4) Within fifteen (15) days following the due date for the filing 
of comments, the Commission will accept concise and factual replies 
from the rival applicants.
    (5) From time to time during the course of this procedure the 
Commission may request additional information from the applicants and 
hold informal conferences at which all competing applicants will have 
the right to be represented.
    (6) Upon evaluation of the applications, the information submitted, 
and such other matters as may be officially noticed the Commission will 
issue a decision granting one (or more) of the proposals which it 
concludes would best serve the public interest, convenience and 
necessity. The decision will report briefly and concisely the reasons 
for the Commission's selection and will deny the other application(s). 
This decision will be considered final.

License Transfers, Modifications, Conditions and Forfeitures


Sec. 101.53  Assignment or transfer of station authorization.

    (a) No station license, or any rights thereunder, may be 
transferred, assigned, or disposed of in any manner, voluntarily or 
involuntarily, directly or indirectly, or by transfer of control of any 
corporation or any other entity holding any such license, to any person 
except upon application to the Commission and upon finding by the 
Commission that the public interest, convenience and necessity will be 
served thereby.
    (b) For purposes of this section, transfers of control requiring 
Commission approval must include any and all transactions that:
    (1) Change the party controlling the affairs of the licensee; or
    (2) Affect any change in a controlling interest in the ownership of 
the licensee, including changes in legal or equitable ownership.
    (c) Requests for transfer of control or assignment authority must 
be submitted on the application form prescribed by Sec. 101.13 or 
Sec. 101.15, and must be accompanied by the applicable showings 
required by Secs. 101.19, 101.21, and 101.55.
    (d) The Commission must be promptly notified in writing when a 
licensee is voluntarily or involuntarily placed in bankruptcy or 
receivership and when an individual licensee, a member of a partnership 
which is a licensee, or a person directly or indirectly in control of a 
corporation which is a licensee, dies or becomes legally disabled. 
Within thirty days after the occurrence of such bankruptcy, 
receivership, death or legal disability, an application of involuntary 
assignment of such license, or involuntary transfer of control of such 
corporation, must be filed with the Commission, requesting assignment 
or transfer to a successor legally qualified under the laws of the 
place having jurisdiction over the assets involved.
    (e) The assignor of a station licensed under this part may retain 
no right of reversion or reassignment of the license and may not 
reserve the right to use the facilities of the station for any period 
whatsoever. No assignment of license will be granted or authorized if 
there is a contract or understanding, express or implied, pursuant to 
which a right of reversion or reassignment of the license or right to 
use the facilities are retained as partial or full consideration for 
the assignment or transfer.
    (f) No special temporary authority, or any rights thereunder, may 
be assigned or otherwise disposed of, directly or indirectly, 
voluntarily or involuntarily, without prior Commission approval.


Sec. 101.55  Considerations involving transfer or assignment 
applications.

    (a) Licenses may not be assigned or transferred prior to the 
completion of construction of the facility. However, consent to the 
assignment or transfer of control of such a license may be given prior 
to the completion of construction where:
    (1) The assignment or transfer does not involve a substantial 
change in or ownership or control of the authorized facilities; or
    (2) The assignment or transfer of control is involuntary due to the 
licensee's bankruptcy, death, or legal disability.
    (b) The Commission will review a proposed transaction to determine 
if the circumstances indicate ``trafficking'' in licenses whenever 
applications (except those involving pro forma assignment or transfer 
of control) for consent to assignment of a license, or for transfer of 
control of a licensee, involve facilities:
    (1) Authorized following a comparative hearing and have been 
operated less than one year;
    (2) Involve facilities that have not been constructed; or
    (3) Involve facilities that were authorized following a random 
selection proceeding in which the successful applicant received 
preference and that have been operated for less than one year.
    (c) At its discretion, the Commission may require the submission of 
an affirmative, factual showing (supported by affidavits of a person or 
persons with personal knowledge thereof) to demonstrate that the 
proposed assignor or transferor has not acquired an authorization or 
operated a station for the principal purpose of profitable sale rather 
than public service. This showing may include, for example, a 
demonstration that the proposed assignment or transfer is due to 
changed circumstances (described in detail) affecting the licensee 
subsequent to the acquisition of the license, or that the proposed 
transfer of radio facilities is incidental to a sale of other 
facilities or merger of interests.

[[Page 26691]]

    (d) If a proposed transfer of radio facilities is incidental to a 
sale or other facilities or merger of interests, any showing requested 
under paragraph (a) of this section must include an additional exhibit 
that:
    (1) Discloses complete details as to the sale of facilities or 
merger of interests;
    (2) Segregates clearly by an itemized accounting, the amount of 
consideration involved in the sale of facilities or merger of 
interests; and
    (3) Demonstrates that the amount of consideration assignable to the 
facilities or business interests involved represents their fair market 
value at the time of the transaction.
    (e) For the purposes of this section, the one year period is 
calculated using the following dates (as appropriate):
    (1) The initial date of grant of the license, excluding subsequent 
modifications;
    (2) The date of consummation of an assignment or transfer, if the 
station is acquired as the result of an assignment of license, or 
transfer of control of corporate licensee; or
    (3) The median date of the applicable commencement dates 
(determined pursuant to paragraphs (d)(1) and (2) of this section) if 
the transaction involves a system (such as a Private Operational Fixed 
Point-to-Point Microwave system) of two or more stations. (The median 
date is that date so selected such that fifty percent of the 
commencement dates of the total number of stations, when arranged in 
chronological order, lie below it and fifty percent lie above it. When 
the number of stations is an even number, the median date will be a 
value half way between the two dates closest to the theoretical 
median).


Sec. 101.57  Modification of station license.

    (a) Except as provided in Sec. 101.59, no modification of a license 
issued pursuant to this part (or the facilities described thereunder) 
may be made except upon application to the Commission.
    (b) No application for modification to extend a license 
construction period will be granted for delays caused by lack of 
financing or for lack of site availability. Applications for time 
extensions for other reasons must include a verified statement from the 
applicant showing that the licensee has made diligent efforts to 
construct the facilities and:
    (1) That additional time is required due to circumstances beyond 
the applicant's control, in which case the applicant must describe such 
circumstances and must set forth with specificity and justify the 
precise extension period requested; or
    (2) That there are unique and overriding public interest concerns 
that justify such an extension, in which case the applicant must 
identify such interests and must set forth and justify a precise 
extension period.
    (c) Notwithstanding the provisions of paragraph (b) of this 
section, when a station license has been assigned or transferred 
pursuant to Sec. 101.53, any extension of time will be limited so that 
the time left to construct after Commission grant of the transfer or 
assignment will be no more than the time remaining for construction at 
the date of the filing of the application for transfer or assignment.
    (d) Modification of license is required for the following changes 
in authorized stations:
    (1) Any change in frequencies used;
    (2) Any change in antenna azimuth;
    (3) Any change in antenna beamwidth;
    (4) Any change in antenna or passive repeater location greater than 
1 second or which involves a requirement for special aeronautical 
study;
    (5) Any change in antenna polarization;
    (6) Any change in antenna height;
    (7) Any change in the size of passive reflectors or repeaters 
associated with the facilities of an authorized station;
    (8) Any increase in emission bandwidth beyond that authorized;
    (9) Any change in the type of emission;
    (10) Any change in authorized equivalent isotropically radiated 
power in excess of 3 dB (a 2-to-1 ratio); or
    (11) Substitution of equipment having a greater frequency 
tolerance.
    (e) When the name of the licensee is changed (without changes in 
the ownership, control, or corporate structure), or when the mailing 
address is changed (without changing the authorized location of the 
fixed station) a formal application for modification of license is not 
required. However, the licensee must notify the Commission within 
thirty days of the effective date of these changes. The notice, which 
may be in letter form, must contain the name and address of the 
licensee as they appear in the Commission's records, the new name or 
address, the call signs and classes of all radio stations authorized to 
the licensee under this part and the radio service in which each 
station is authorized. The notice must be sent to the Federal 
Communications Commission, Gettysburg, PA 17325 and a copy must be 
maintained with the license of each station until a new license is 
issued.


Sec. 101.59  Processing of applications for facility minor 
modifications.

    (a) Unless an applicant is notified to the contrary by the 
Commission, as of the twenty-first day following the date of public 
notice, any application that meets the requirements of paragraph (b) of 
this section and proposes only the change specified in paragraph (c) of 
this section will be deemed to have been authorized by the Commission.
    (b) An application may be considered under the procedures of this 
section only if:

60 day period does not exceed the appropriate values prescribed by 
paragraph (c) of this section; and
    (3) The Commission is notified of changes made to facilities by the 
submission of a completed FCC Form 494 within thirty days after the 
changes are made.
    (c) Modifications that may be made without prior authorization 
under paragraph (b) of this section are:
    (1) Change or modification of a transmitter, when:
    (i) The replacement or modified transmitter is type-accepted (or 
type-notified) for use under this part and is installed without 
modification from the type-accepted (or type notified) configuration;
    (ii) The type of modulation is not changed;
    (iii) The frequency stability is equal to or better than the 
previously authorized frequency stability; and
    (iv) The necessary bandwidth and the output power do not exceed the

    (8) Changes to the transmission line and other devices between the 
transmitter and the antenna when the effective radiated power of the 
station is not increased by more than one dB.
    (d) Licensees may notify the Commission of permissible changes or 
correct erroneous information on a license not involving a major change 
(i.e., a change that would be classified as a major amendment as 
defined by Sec. 101.29) without obtaining prior Commission approval by 
filing FCC Form 494.


Sec. 101.63  Period of construction; certification of completion of 
construction.

    (a) Each station authorized under this part must be in operation 
within 18 months from the initial date of grant. Modification of an 
operational station must be completed within 18 months of the date of 
grant of the applicable modification request.
    (b) Failure to timely begin operation means the authorization 
cancels automatically and must be returned to the Commission.
    (c) The frequencies associated with all point-to-multipoint 
authorizations which have cancelled automatically or otherwise been 
recovered by the Commission will again be made available for 
reassignment on a date and under terms set forth by Public Notice.
    (d) Requests for extension of time to be in operation may be 
granted upon a showing of good cause, setting forth in detail the 
applicant's reasons for failure to have the facility operating in the 
prescribed period. Such requests must be submitted no later than 30 
days prior to the end of the prescribed period to the Federal 
Communications Commission, Gettysburg, PA 17325-7245.
    (e) Construction of any station must be completed by the date 
specified in the license as the termination date of the construction 
period. Licensees who fail to complete construction must return their 
authorization for cancellation within 5 days after the expiration of 
the construction period specified on the license.


Sec. 101.65  Forfeiture and termination of station authorizations.

    (a) A license will be automatically forfeited in whole or in part 
without further notice to the licensee upon:
    (1) The expiration of the construction period specified therein, or 
after such additional time as may be authorized by the Commission;
    (2) The expiration of the license period specified therein, unless 
prior

[[Page 26693]]

thereto an application for renewal of such license has been filed with 
the Commission; or
    (3) The voluntary removal or alteration of the facilities, so as to 
render the station not operational for a period of 30 days or more.
    (b) A license forfeited in whole or in part under the provisions of 
paragraph (a)(1) or (a)(2) of this section may be reinstated if the 
Commission, in its discretion, determines that reinstatement would best 
serve the public interest, convenience and necessity. Petitions for 
reinstatement filed pursuant to this subsection will be considered only 
if:
    (1) The petition is filed within 30 days of the expiration date set 
forth in paragraph (a)(1) or (a)(2) of this section, whichever is 
applicable;
    (2) The petition explains the failure to timely file such 
notification or application as would have prevented automatic 
forfeiture; and
    (3) The petition sets forth with specificity the procedures which 
have been established to insure timely filings in the future.
    (c) A special temporary authorization will automatically terminate 
upon the expiration date specified therein, or upon failure to comply 
with any special terms or conditions set forth therein. Operation may 
be extended beyond such termination date only after application and 
upon specific authorization by the Commission.
    (d) If a station licensed under this part discontinues operation on 
a permanent basis, the licensee must forward the station license to the 
Federal Communications Commission, Gettysburg, Pennsylvania 17325, for 
cancellation. For purposes of this section, any station which has not 
operated for one year or more is considered to have been permanently 
discontinued. See Sec. 101.305 for additional rules regarding temporary 
and permanent discontinuation of service.


Sec. 101.67  License period.

    Licenses for stations authorized under this part will be issued for 
a period not to exceed 10 years. Unless otherwise specified by the 
Commission, the expiration of regular licenses shall be on the date 
(month and day) selected by licensees in the year of expiration.


Sec. 101.69  Transition of the 2.11-2.13, and 2.16-2.18 GHz bands from 
the Common Carrier Fixed Point-to-Point Microwave Services and the 
1.85-1.99, 2.13-2.15, and 2.18-2.20 GHz bands from the Private 
Operational Fixed Point-to-Point Microwave Service to emerging 
technologies.

    (a) Licensees proposing to implement services using emerging 
technologies (ET Licensees) may negotiate with Common Carrier and 
Private Operational Fixed Point-to-Point Microwave Service licensees 
(Existing Licensees) in these bands for the purpose of agreeing to 
terms under which the Existing Licensees would relocate their 
operations to other fixed microwave bands or to other media, or 
alternatively, would accept a sharing arrangement with the ET Licensee 
that may result in an otherwise impermissible level of interference to 
the existing licensee's operations. ET Licensees may also negotiate 
agreements for relocation of the Existing Licensees' facilities within 
the 2 GHz band in which all interested parties agree to the relocation 
of the Existing Licensee's facilities elsewhere within these bands. 
``All interested parties'' includes the incumbent licensee, the 
emerging technology provider or representative requesting and paying 
for the relocation, and any emerging technology licensee of the 
spectrum to which the incumbent's facilities are to be relocated.
    (b) Common Carrier and Private Operational Fixed Point-to-Point 
Microwave Service licensees, with the exception of public safety 
facilities defined in paragraph (f) of this section, in bands allocated 
for licensed emerging technology services will maintain primary status 
in these bands until two years after the Commission commences 
acceptance of applications for an emerging technology service (two-year 
voluntary negotiation period), and until one year after an emerging 
technology service licensee initiates negotiations for relocation of 
the fixed microwave licensee's operations (one-year mandatory 
negotiation period) or, in bands allocated for unlicensed emerging 
technology services, until one year after an emerging technology 
unlicensed equipment supplier or representative initiates negotiations 
for relocation of the fixed microwave licensee's operations (one-year 
mandatory negotiation period). When it is necessary for an emerging 
technology provider or representative of unlicensed device 
manufacturers to negotiate with a fixed microwave licensee with 
operations in spectrum adjacent to that of the emerging technology 
provider, the transition schedule of the entity requesting the move 
will apply. Public safety facilities defined in paragraph (f) of this 
section will maintain primary status in these bands until three years 
after the Commission commences acceptance of applications for an 
emerging technology service (three-year voluntary negotiation period), 
and until two years after an emerging technology service licensee or an 
emerging technology unlicensed equipment supplier or representative 
initiates negotiations for relocation of the fixed microwave licensee's 
operations (two-year mandatory negotiation period).
    (c) The Commission will amend the operation license of the Common 
Carrier and Private Operational Fixed Point-to-Point Microwave Service 
operator to secondary status only if the following requirements are 
met:
    (1) The service applicant, provider, licensee, or representative 
using an emerging technology guarantees payment of all relocation 
costs, including all engineering, equipment, site and FCC fees, as well 
as any reasonable, additional costs that the relocated fixed microwave 
licensee might incur as a result of operation in another fixed 
microwave band or migration to another medium;
    (2) The emerging technology service entity 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; and
    (3) The emerging technology service entity builds the replacement 
system and tests it for comparability with the existing 2 GHz system.
    (d) The 2 GHz microwave 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.
    (e) If within one year after the relocation to new facilities the 2 
GHz microwave licensee demonstrates that the new facilities are not 
comparable to the former facilities, the emerging technology service 
entity must remedy the defects or pay to relocate the microwave 
licensee back to its former or equivalent 2 GHz frequencies.
    (f) Public safety facilities subject to the three-year voluntary 
and two-year mandatory negotiation periods, are those that the majority 
of communications carried are used for police, fire, or emergency 
medical services operations involving safety of life and property. The 
facilities within this exception are those facilities

[[Page 26694]]

currently licensed on a primary basis pursuant to the eligibility 
requirements of Sec. 90.19 of this chapter, Police Radio Service; 
Sec. 90.21 of this chapter, Fire Radio Service; Sec. 90.27 of this 
chapter Emergency Medical Radio Service; and subpart C of part 90 of 
this chapter, Special Emergency Radio Services. Licensees of other part 
101 facilities licensed on a primary basis under the eligibility 
requirements of subparts B and C, part 90 of this chapter, are 
permitted to request similar treatment upon demonstrating that the 
majority of the communications carried on those facilities are used for 
operations involving safety of life and property.

(1)--Applications for frequencies in the 932.5-935/941.5-944 MHz bands may be filed initially during a one-week period to be announced by public notice.
  After these applications have been processed, the Commission will announce by public notice a filing date for remaining frequencies. From this filing 
  date forward, applications will be processed on a daily first-come, first-served basis.                                                               

Sec. 101.103  Frequency coordination procedures.

    (a) Assignment of frequencies will be made only in such a manner as 
to facilitate the rendition of communication service on an 
interference-free basis in each service area. Unless otherwise 
indicated, each frequency available for use by stations in these 
services will be assigned exclusively to a single applicant in any 
service area. All applicants for, and licensees of, stations in these 
services must cooperate in the selection and use of the frequencies 
assigned in order to minimize interference and thereby obtain the most 
effective use of the authorized facilities. In the event harmful 
interference occurs or appears likely to occur between two or more 
radio systems and such interference

[[Page 26695]]

cannot be resolved between the licensees thereof, the Commission may 
specify a time sharing arrangement for the stations involved or may, 
after notice and opportunity for hearing, require the licensees to make 
such changes in operating techniques or equipment as it may deem 
necessary to avoid such interference.
    (b) The provisions of this section do not apply to operations in 
the band 31.0 to 31.3 GHz. Operations in this band are unprotected and 
subject to harmful interference from other licensed operations in this 
band.
    (c) Frequency diversity transmission will not be authorized in 
these services in the absence of a factual showing that the required 
communications cannot practically be achieved by other means. Where 
frequency diversity is deemed to be justified on a protection channel 
basis, it will be limited to one protection channel for the bands 
3,700-4,200, 5925-6425, and 6525-6875 MHz, and a ratio of one 
protection channel for three working channels for the bands 10,550-
10,680 and 10,700-11,700 MHz. In the bands 3,700-4,200, 5,925-6,425, 
and 6525-6875 MHz, no frequency diversity protection channel will be 
authorized unless there is a minimum of three working channels, except 
that where a substantial showing is made that a total of three working 
channels will be required within three years, a protection channel may 
be authorized simultaneously with the first working channel. A 
protection channel authorized under such exception will be subject to 
termination if applications for the third working channel are not filed 
within three years of the grant date of the applications for the first 
working channel. Where equipment employing digital modulation 
techniques with cross-polarized operation on the same frequency is 
used, the protection channel authorized under the above conditions may 
be considered to consist of both polarizations of the protection 
frequency where such is shown to be necessary.
    (d) Frequency coordination. For each frequency authorized under 
this part, the following frequency usage coordination procedures will 
apply:
    (1) General requirements. Proposed frequency usage must be prior 
coordinated with existing licensees, permittees and applicants in the 
area, and other applicants with previously filed applications, whose 
facilities could affect or be affected by the new proposal in terms of 
frequency interference on active channels, applied-for channels, or 
channels coordinated for future growth. Coordination must be completed 
prior to filing an application for regular authorization, or an 
amendment to a pending application, or any major modification to a 
license. In coordinating frequency usage with stations in the fixed 
satellite service, applicants must also comply with the requirements of 
Sec. 101.21(f). In engineering a system or modification thereto, the 
applicant must, by appropriate studies and analyses, select sites, 
transmitters, antennas and frequencies that will avoid interference in 
excess of permissible levels to other users. All applicants and 
licensees 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, the party being 
coordinated with is not obligated to suggest changes or re-engineer a 
proposal in cases involving conflicts. Applicants should make every 
reasonable effort to avoid blocking the growth of systems as prior 
coordinated. The applicant must identify in the application all 
entities with which the technical proposal was coordinated. In the 
event that technical problems are not resolved, an explanation must be 
submitted with the application. 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 
interference in excess of permissible levels (such as the use of 
artificial site shielding) or would result in a reduction of quality or 
capacity of either system, the details thereof may be contained in the 
application.
    (2) Coordination procedure guidelines are as follows:
    (i) Coordination involves two separate elements: notification and 
response. Both or either may be oral or in written form. To be 
acceptable for filing, all applications and major technical amendments 
must certify that coordination, including response, has been completed. 
The names of the licensees, permittees and applicants with coordinated 
proposals, applicants, permittees, and licensees with which 
coordination was accomplished must be specified. If such notice and/or 
response is oral, the party providing such notice or response must 
supply written documentation of the communication upon request;
    (ii) Notification must include relevant technical details of the 
proposal. At minimum, this should include, as applicable, the 
following:

Applicant's name and address.
Transmitting station name.
Transmitting station coordinates.
Frequencies and polarizations to be added, changed or deleted.
Transmitting equipment type, its stability, actual output power, 
emission designator, and type of modulation (loading).
Transmitting antenna type(s), model, gain and, if required, a 
radiation pattern provided or certified by the manufacturer.
Transmitting antenna center line height(s) above ground level and 
ground elevation above mean sea level.
Receiving station name.
Receiving station coordinates.
Receiving antenna type(s), model, gain, and, if required, a 
radiation pattern provided or certified by the manufacturer.
Receiving antenna center line height(s) above ground level and 
ground elevation above mean sea level.
Path azimuth and distance.
Estimated transmitter transmission line loss expressed in dB.
Estimated receiver transmission line loss expressed in dB.

    Note: The position location of antenna sites shall be determined 
to an accuracy of no less than 1 second in the 
horizontal dimensions (latitude and longitude) and 1 
meter in the vertical dimension (ground elevation) with respect to 
the National Spacial Reference System.

    (iii) For transmitters employing digital modulation techniques, the 
notification should clearly identify the type of modulation. Upon 
request, additional details of the operating characteristics of the 
equipment must also be furnished;
    (iv) Response to notification should be made as quickly as 
possible, even if no technical problems are anticipated. Any response 
to notification indicating potential interference must specify the 
technical details and must be provided to the applicant, in writing, 
within the 30-day notification period. Every reasonable effort should 
be made by all applicants, permittees and licensees to eliminate all 
problems and conflicts. If no response to notification is received 
within 30 days, the applicant will be deemed to have made reasonable 
efforts to coordinate and may file its application without a response;
    (v) The 30-day notification period is calculated from the date of 
receipt by the applicant, permittee, or licensee being notified. If 
notification is by mail, this date may be ascertained by:
    (A) The return receipt on certified mail;
    (B) The enclosure of a card to be dated and returned by the 
recipient; or
    (C) A conservative estimate of the time required for the mail to 
reach its destination. In the last case, the estimated date when the 
30-day period would expire should be stated in the notification.
    (vi) An expedited prior coordination period (less than 30 days) may 
be requested when deemed necessary by a notifying party. The 
coordination notice should be identified as ``expedited'' and

[[Page 26696]]

the requested response date should be clearly indicated. However, 
circumstances preventing a timely response from the receiving party 
should be accommodated accordingly. It is the responsibility of the 
notifying party to receive written concurrence (or verbal, with written 
to follow) from affected parties or their coordination representatives.
    (vii) All technical problems that come to light during coordination 
must be resolved unless a statement is included with the application to 
the effect that the applicant is unable or unwilling to resolve the 
conflict and briefly the reason therefor;
    (viii) Where a number of technical changes become necessary for a 
system during the course of coordination, an attempt should be made to 
minimize the number of separate notifications for these changes. Where 
the changes are incorporated into a completely revised notice, the 
items that were changed from the previous notice should be identified. 
When changes are not numerous or complex, the party receiving the 
changed notification should make an effort to respond in less than 30 
days. When the notifying party believes a shorter response time is 
reasonable and appropriate, it may be helpful for that party to so 
indicate in the notice and perhaps suggest a response date;
    (ix) If, after coordination is successfully completed, it is 
determined that a subsequent change could have no impact on some 
parties receiving the original notification, these parties must be 
notified of the change and of the coordinator's opinion that no 
response is required;
    (x) Applicants, permittees and licensees should supply to all other 
applicants, permittees and licensees within their areas of operations, 
the name, address and telephone number of their coordination 
representatives. Upon request from coordinating applicants, permittees 
and licensees, data and information concerning existing or proposed 
facilities and future growth plans in the area of interest should be 
furnished unless such request is unreasonable or would impose a 
significant burden in compilation;
    (xi) Parties should keep other parties with whom they are 
coordinating advised of changes in plans for facilities previously 
coordinated. If applications have not been filed 6 months after 
coordination was initiated, parties may assume that such frequency use 
is no longer desired unless a second notification has been received 
within 10 days of the end of the 6 month period. Renewal notifications 
are to be sent to all originally notified parties, even if coordination 
has not been successfully completed with those parties; and
    (xii) Any frequency reserved by a licensee for future use in the 
bands subject to this part must be released for use by another 
licensee, permittee or applicant upon a showing by the latter that it 
requires an additional frequency and cannot coordinate one that is not 
reserved for future use.
    (e) Where frequency conflicts arise between co-pending applications 
in the Private Operational Fixed Point-to-Point Microwave, Common 
Carrier Fixed Point-to-Point Microwave and Local Television 
Transmission Services, it is the obligation of the later filing 
applicant to amend his application to remove the conflict, unless it 
can make a showing that the conflict cannot be reasonably eliminated. 
Where a frequency conflict is not resolved and no showing is submitted 
as to why the conflict cannot be resolved, the Commission may grant the 
first filed application and dismiss the later filed application(s) 
after giving the later filing applicant(s) 30 days to respond to the 
proposed action.
    (f) When the proposed facilities are to be operated in the band 
12,500-12,700 MHz, applications must also follow the procedures in 
Sec. 101.21 and the technical standards and requirements of part 25 of 
this chapter as regards licensees in the Communication-Satellite 
Service.


Sec. 101.105  Interference protection criteria.

    (a) The interference protection criteria for fixed stations subject 
to this part are as follows:
    (1) To long-haul analog systems, employing frequency modulated 
radio and frequency division multiplexing to provide multiple voice 
channels, the allowable interference level per exposure:
    (i) Due to co-channel sideband-to-sideband interference must not 
exceed 5 pwpO (Picowatts of absolute noise power psophometrically 
weighted (pwpO), appearing in an equivalent voice band channel of 300-
3400 Hz); or
    (ii) Due to co-channel carrier-beat interference must not exceed 50 
pwpO.
    (2) To short-haul analog systems employing frequency modulated 
radio and frequency division multiplexing to provide multiple voice 
channels, the allowable interference level per exposure:
    (i) Due to co-channel sideband-to-sideband interference must not 
exceed 25 pwpO except in the 952-960 MHz band interference into single 
link fixed relay and control stations must not exceed 250 pwpO per 
exposure; or
    (ii) Due to co-channel carrier-beat interference must not exceed 50 
pwpO except in the 952-960 MHz band interference into single link fixed 
relay and control stations must not exceed 1000 pwpO per exposure.
    (3) FM-TV. In analog systems employing frequency modulated radio 
that is modulated by a standard, television (visual) signal, the 
allowable interference level per exposure may not exceed the levels 
which would apply to long-haul or short-haul FM-FDM systems, as 
outlined in paragraphs (b) (1) and (2) of this section, having a 600-
1200 voice channel capacity.
    (b) In addition to the requirements of paragraph (a) of this 
section the adjacent channel interference protection criteria to be 
afforded, regardless of system length, or type of modulation, 
multiplexing, or frequency band, must be such that the interfering 
signal does not produce more than 1.0 dB degradation of the practical 
threshold of the protected receiver. The ``practical threshold'' of the 
protected receiver can be based upon the definition in TSB 10, 
referenced in paragraph (c) of this section, or upon alternative 
generally acceptable good engineering standards.
    (c) Applying the Criteria.
    (1) Guidelines for applying the interference protection criteria 
for fixed stations subject to this part are specified in the 
Telecommunications Industry Association's Telecommunications Systems 
Bulletin TSB 10, ``Interference Criteria for Microwave Systems'' (TSB 
10). Other procedures that follow generally acceptable good engineering 
practices are also acceptable to the Commission.
    (2) If TSB 10 guidelines cannot be used, the following interference 
protection criteria may be used by calculating the ratio in dB between 
the desired (carrier signal) and the undesired (interfering) signal (C/
I ratio) appearing at the input to the receiver under investigation 
(victim receiver): Except as provided in Sec. 101.147 where the 
applicants proposed facilities are of a type not included in paragraphs 
(a) and (b) of this section or where the development of the carrier-to-
interference (C/I) ratio is not covered by generally acceptable 
procedures, or where the applicant does not wish to develop the 
carrier-to-interference ratio, the applicant must, in the absence of 
criteria or a developed C/I ratio, employ the following C/I protection 
ratios:
    (i) Co-channel interference: Both sideband and carrier-beat, 
applicable to all bands; the existing or previously authorized system 
must be afforded a carrier to interfering signal protection ratio of at 
least 90 dB except in the 952-

[[Page 26697]]

960 MHz band where it must be 75 dB; or
    (ii) Adjacent channel interference: Applicable to all bands; the 
existing or previously authorized system must be afforded a carrier to 
interfering signal protection ratio of at least 56 dB.
    (3) Applicants for frequencies listed in Sec. 101.147(b)(1) must 
make the following showings that protection criteria have been met over 
the entire service area of existing systems. Such showings may be made 
by the applicant or may be satisfied by a statement from a frequency 
coordinator.
    (i) For multiple address stations in the 928-929/952-960 MHz bands, 
a statement that the proposed system complies with the following co-
channel separations from all existing stations and pending 
applications:

Fixed-to-fixed--145 km;
Fixed-to-mobile--113 km:
Mobile-to-mobile 81 km

    Note to (3)(i): Multiple address systems employing only remote 
stations will be treated as mobile for the purposes of determining 
the appropriate separation. For mobile operation, the mileage is 
measured from the reference point specified on the license 
application. For fixed operation on subfrequencies in accordance 
with Sec. 101.147 the mileage also is measured from the reference 
point specified on the license application;

    (ii) For multiple address stations in the 932-932.5/941-941.5 MHz 
bands, a statement that the proposed system complies with the following 
co-channel separation from all existing stations and pending 
applications:

Fixed-to-fixed--113 Km

    (iii) In cases where the geographic separation standard in 
paragraphs (c)(3)(i) and (c)(3)(ii) of this section are not followed, 
an engineering analysis must be submitted to show the coordination of 
the proposed assignment with existing systems located closer than those 
standards. The engineering analyses will include:
    (A) Specification of the interference criteria and system 
parameters used in the interference study;
    (B) Nominal service areas of each system included in the 
interference analysis.;
    (C) Modified service areas resulting from the proposed system. The 
propagation models used to establish the service boundary limits must 
be specified and any special terrain features considered in computing 
the interference impact should be described; and
    (D) A statement that all parties affected have agreed to the 
engineering analysis and will accept the calculated levels of 
interference.
    (4) Multiple address systems operating on subfrequencies in 
accordance with Sec. 101.147 that propose to operate master stations at 
unspecified locations must define the operating area by a radius about 
a geographical coordinate and describe how interference to co-channel 
users will be controlled.
    (5) Multiple address frequencies in the 956 MHz band may be 
assigned for use by mobile master stations on a primary basis. Multiple 
address frequencies in the 952 MHz band may be assigned for use by 
mobile master stations on a case-by-case basis. Mobile operation in the 
952 MHz band will be on a secondary basis to fixed operations.
    (6) Each application for new or modified nodal station on channels 
numbered 4A, 4B, 7, 9, and 19/20 in the 10.6 GHz band and all point-to-
multipoint channels in the 18 GHz band must demonstrate that all 
existing co-channel stations are at least 56 kilometers from the 
proposed nodal station site. Applicants for these channels must certify 
that all licensees and applicants for stations on the adjacent channels 
within 56 kilometers of the proposed nodal station have been notified 
of the proposed station and do not object. Alternatively, or if one of 
the affected adjacent channel interests does object, the applicant may 
show that all affected adjacent channel parties are provided a C/I 
protection ratio of 0 dB. An applicant proposing to operate at an AAT 
greater than 91 meters must reduce its EIRP in accordance with the 
following table; however, in no case may EIRP exceed 70 dBm on the 10.6 
GHz channels.

    (7) Each application for new or modified nodal station on channels 
numbered 21, 22, 23, and 24 in the 10.6 GHz band must include an 
analysis of the potential for harmful interference to all other 
licensed and previously applied for co-channel and adjacent channel 
station located within 80 kilometers of the location of the proposed 
station. The criteria contained in Sec. 101.103(d)(2) must be used in 
this analysis. Applicants must certify that copies of this analysis 
have been served on all parties which might reasonably be expected to 
receive interference above the levels set out in Sec. 101.103(d)(2) 
within 5 days of the date the subject application is filed with the 
Commission.
    (8) If the potential interference will exceed the prescribed 
limits, a statement shall be submitted with the application for new or 
modified stations to the effect that all parties have agreed to accept 
the higher level of interference.
    (d) Effective August 1, 1985, when a fixed station that conforms to 
the technical standards of this subpart (or, in the case of the 12,200-
12,700 MHz band, a direct broadcast satellite station) receives or will 
receive interference in excess of the levels specified in this section 
as a result of an existing licensee's use of non-conforming equipment 
authorized between July 20, 1961 and July 1, 1976, and the interference 
would not result if the interfering station's equipment complied with 
the current technical standards, the licensee of the non-conforming 
station must take whatever steps are necessary to correct the situation 
up to the point of installing equipment which fully conforms to the 
technical standards of this subpart. In such cases, if the engineering 
analysis demonstrates that:
    (1) The conforming station would receive interference from a non-
conforming station in excess of the levels specified in this section; 
and
    (2) The interference would be eliminated if the non-conforming 
equipment were replaced with equipment which complies with the 
standards of this subpart, the licensee (or prospective licensee) of 
the station which would receive interference must provide written 
notice of the potential interference to both the non-conforming 
licensee and the Commission's office in Gettysburg, PA. The non-
conforming licensee must make all required equipment changes within 180 
days from the date of official Commission notice informing the licensee 
that it must upgrade its equipment, unless an alternative solution has 
been agreed to by all parties involved in the interference situation. 
If a non-conforming licensee fails to make all required changes within 
the specified period of time, the Commission may require the licensee 
to suspend operation until the changes are completed.
    (e) Interference Dispute Resolution Procedures. Should a licensee 
licensed under this part receive harmful interference from another 
licensee licensed under this chapter, the parties involved shall comply 
with the dispute resolution procedures set forth herein:

[[Page 26698]]

    (1) The licensee experiencing the harmful interference shall notify 
the licensee believed to be causing the harmful interference and shall 
supply information describing its problem and supporting its claim;
    (2) Upon receipt of the harmful interference notice, the licensee 
alleged to be causing the harmful interference shall respond 
immediately and make every reasonable effort to identify and resolve 
the conflict; and
    (3) Licensees are encouraged to resolve the harmful interference 
prior to contacting the Commission.


Sec. 101.107  Frequency tolerance.

    (a) The carrier frequency of each transmitter authorized in these 
services must be maintained within the following percentage of the 
reference frequency except as otherwise provided in paragraph (b) of 
this section or in the applicable subpart of this part (unless 
otherwise specified in the instrument of station authorization the 
reference frequency will be deemed to be the assigned frequency):

------------------------------------------------------------------------
\1\ Applicable only to common carrier LTTS stations. Beginning Aug. 9,  
  1975, this tolerance will govern the marketing of LTTS equipment and  
  the issuance of all such authorizations for new radio equipment. Until
  that date new equipment may be authorized with a frequency tolerance  
  of .03 percent in the frequency range 2,200 to 10,500 MHz and .05     
  percent in the range 10,500 MHz to 12,200 MHz, and equipment so       
  authorized may continue to be used for its life provided that it does 
  not cause interference to the operation of any other licensee.        
\2\ Equipment authorized to be operated on frequencies between 890 and  
  940 MHz as of Oct. 15, 1956, must maintain a frequency tolerance      
  within 0.03 percent subject to the condition that no harmful          
  interference is caused to any other radio station.                    
\3\ See subpart G of this part for the stability requirements for       
  transmitters used in the Digital Electronic Message Service.          
\4\ Existing type accepted equipment with a frequency tolerance of 0.03% may be marketed until December 1, 1988. Equipment         
  installed and operated prior to December 1, 1988 may continue to      
  operate after that date with a minimum frequency tolerance of 0.03%. However, the replacement of equipment requires that the  
  0.003% tolerance be met.                                  
\5\ For remote stations with 12.5 KHz bandwidth, the tolerance is 0.00015%.                                                       
\6\ Applicable to private operational fixed point-to-point microwave    
  only. For exceptions see Sec.  101.147.                               
\7\ For private operational fixed point-to-point microwave systems, with
  a channel greater than or equal to 50 KHz bandwidth, 0.0005%; for multiple address master stations, regardless of    
  bandwidth, 0.00015%; for multiple address remote stations 
  with 12.5 KHz bandwidths, 0.00015%; for multiple address  
  remote stations with channels greater than 12.5 KHz bandwidth, 0.0005%.                                                        

    (b) Heterodyne microwave radio systems may be authorized at a 
somewhat less restrictive frequency tolerance (up to .01 percent) to 
compensate for frequency shift caused by numerous repeaters between 
base band signal insertion. Where such relaxation is sought, applicant 
must provide all calculations and indicate the desired tolerance over 
each path. In such instances the radio transmitters and receivers used 
must individually be capable of complying with the tolerance specified 
in paragraph (a) of this section. Heterodyne operation is restricted to 
channel bandwidth of 10 MHz or greater.
    (c) As an additional requirement in any band where the Commission 
makes assignments according to a specified channel plan, provisions 
must be made to prevent the emission included within the occupied 
bandwidth from radiating outside the assigned channel at a level 
greater than that specified in Sec. 101.111.


Sec. 101.109  Bandwidth.

    (a) Each authorization issued pursuant to these rules will show, as 
the emission designator, a symbol representing the class of emission 
which must be prefixed by a number specifying the necessary bandwidth. 
This figure does not necessarily indicate the bandwidth actually 
occupied by the emission at any instant. In those cases where part 2 of 
this chapter does not provide a formula for the computation of the 
necessary bandwidth, the occupied bandwidth may be used in the emission 
designator.
    (b) Stations in this service will be authorized any type of 
emission, method of modulation, and transmission characteristic, 
consistent with efficient use of the spectrum and good engineering 
practice, except that Type B, damped-wave emission will not be 
authorized.
    (c) The maximum bandwidth which will be authorized per frequency 
assigned is set out in the table that follows. Regardless of the 
maximum authorized bandwidth specified for each frequency band, the 
Commission reserves the right to issue a license for less than the 
maximum bandwidth if it

[[Page 26699]]

appears that a lesser bandwidth would be sufficient to support an 
applicant's intended communications.

    (a) 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 values specified below. 
In cases of harmful interference, the Commission may, after notice and 
opportunity for hearing, order a change in the effective radiated power 
of this station. Further, the output power of a transmitter on any 
authorized frequency in this service may not exceed the following:

  power in terms of the watts specified is the peak envelope power of   
  the emission measured at the associated antenna input port. The       
  operating power shall not exceed the authorized power by more than 10 
  percent of the authorized power in watts at any time.                 
\6\ Maximum power delivered to the antenna shall not exceed -3 dBW.

    (b) The power of transmitters that use Automatic Transmitter Power 
Control shall not exceed the power input or output specified in the 
instrument of station authorization. The power of non-ATPC transmitters 
shall be maintained as near as practicable to the power input or output 
specified in the instrument of station authorization.


Sec. 101.115  Directional antennas.

    (a) Unless otherwise authorized upon specific request by the 
applicant, each station authorized under the rules of this part 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. New Periscope antenna systems 
will not, under ordinary circumstances, be authorized.
    (b) Stations operating below 932.5 MHz that are required to use 
directional antennas must employ antennas meeting the standards 
indicated below. (Maximum beamwidth is for the major lobe of radiation 
at the half power points. Suppression is the minimum attenuation 
required for any secondary lobe signal and is referenced to the maximum 
signal in the main lobe.)

    (c) Fixed stations (other than temporary fixed stations and DEMS 
nodal stations) operating at 932.5 MHz or higher must employ 
transmitting and receiving antennas (excluding second receiving 
antennas for operations such as space diversity) meeting the 
appropriate performance Standard A indicated below, except that in 
areas not subjected to frequency congestion antennas meeting 
performance Standard B may be used subject to the

*\1\ DEMS User Station antennas in this band must meet performance Standard B and have a minimum antenna gain of 34 dBi. The maximum beamwidth          
  requirement does not apply to DEMS User Stations. DEMS Nodal Stations need not comply with these standards.                                           
\2\ The minimum front-to-back ratio must be 38 dBi.                                                                                                     
\3\ Mobile, except aeronautical mobile, stations need not comply with these standards.                                                                  
\4\ Except for antennas between 140 deg. and 180 deg. authorized or pending on January 1, 1989, in the band 10,550 to 10,565 MHz for which minimum      
  radiation to suppression to angle (in degrees) from centerline of main beam is 36 decibels.                                                           
\5\ These antenna standards apply to all point-to-point stations authorized after June 1, 1997. Existing licensees and pending applicants on that date  
  are grandfathered and need not comply with these standards.                                                                                           
\6\ These antenna standards apply to all point-to-point stations authorized on or before June 1, 1997.                                                  
\7\ These antenna standards apply only to DEMS User Stations licensed, in operation, or applied for prior to July 15, 1993.                             
\8\ Except for Multiple Address System frequencies listed in where omnidirectional antennas may be used.                                                
\9\ Antennas used at outlying stations as part of a central protection alarm system need conform to only the following 2 standards: (i) The minimum on- 
  beam forward gain must be at least 10 dBi; and (ii) the minimum front-to-back ratio must be at least 20 dB.                                           
\10\ Except as provided in Sec.  101.147(t). Note to paragraph (10): Stations must employ an antenna that meets the performance standards for Category  
  A, except that in areas not subject to frequency congestion, antennas meeting standards for Category B may be employed. Note, however, that the       
  Commission may require the use of high performance antennas where interference problems can be resolved by the use of such antennas.                  
\11\ Omnidirectional antennas may be authorized in the band 2150-2160 MHz.                                                                              
\12\ Except for temporary-fixed operations in the band 13200-13250 MHz with output powers less than 250 mW and as provided in Sec.  101.147(q).         

    (d) The Commission shall require the replacement of any antenna or 
periscope antenna system of a permanent fixed station operating at 
932.5 MHz or higher that does not meet performance Standard A specified 
in paragraph (c) of this section, at the expense of the licensee 
operating such antenna, upon a showing that said antenna causes or is 
likely to cause interference to (or receive interference from) any 
other authorized or applied for station whereas a higher performance 
antenna is not likely to involve such interference. Antenna performance 
is expected to meet the standards of paragraph (c) of this section for 
parallel polarization. For cases of potential interference, an antenna 
will

[[Page 26702]]

not be considered to meet Standard A unless the parallel polarization 
performance for the discrimination angle involved meets the 
requirements, even if the cross-polarization performance controls the 
interference.
    (e) In cases where passive reflectors are employed in conjunction 
with transmitting antenna systems, the foregoing paragraphs of this 
section also will be applicable. However, in such instances, the center 
of the major lobe of radiation from the antenna normally must be 
directed at the passive reflector, and the center of the major lobe of 
radiation from the passive reflector directed toward the receiving 
station with which it communicates.
    (f) Periscope antennas used at an electric power facility plant 
area will be excluded from the requirements of paragraph (c) of this 
section on a case-by-case basis where technical considerations or 
safety preclude the use of other types of antenna systems.
    (g) In the event harmful interference is caused to the operation of 
other stations, the Commission may, after notice and opportunity for 
hearing, order changes to be made in the height, orientation, gain and 
radiation pattern of the antenna system.


Sec. 101.117  Antenna polarization.

    Except as set forth herein, stations operating in the radio 
services included in this part are not limited as to the type of 
polarization of the radiated signal, provided, however, that in the 
event interference in excess of permissible levels is caused to the 
operation of other stations the Commission may, after notice and 
opportunity for hearing, order the licensee to change the polarization 
of the radiated signal. No change in polarization may be made without 
prior authorization from the Commission. Unless otherwise allowed, only 
linear polarization (horizontal or vertical) shall be used.


Sec. 101.119  Simultaneous use of common antenna structures.

    The simultaneous use of common antenna structures by more than one 
radio station, or by one of more domestic public radio stations and one 
or more stations of any other class or service, may be authorized: 
provided, however, that each licensee or user of any such structure is 
responsible for maintaining the structure, and for painting and 
illuminating the structure when obstruction marking is required by the 
Commission. (See Sec. 101.21(a).)


Sec. 101.121  Marking of antenna structures.

    The owner of each antenna structure required to be painted and/or 
illuminated under the provision of section 303(q) of the Communications 
Act of 1934, as amended, shall operate and maintain the antenna 
structure painting and lighting in accordance with part 17 of this 
chapter. In the event of default by the owner, each licensee or 
permittee shall be individually responsible for conforming to the 
requirements pertaining to antenna structure painting and lighting. For 
complete regulations relative to antenna marking requirements, see part 
17 of this chapter.


Sec. 101.123  Quiet zones.

    Quiet zones are those areas where it is necessary to restrict 
radiation so as to minimize possible impact on the operations of radio 
astronomy or other facilities that are highly sensitive to radio 
frequency interference.
    (a) In order to minimize possible harmful interference at the 
National Radio Astronomy Observatory site located at Green Bank, 
Pocohontas County, W. Va., and at the Naval Radio Research Observatory 
site at Sugar Grove, Pendleton County, W. Va., any applicant for a 
station authorization other than temporary-fixed seeking a station 
license for a new station or to modify an existing station in a manner 
which would change either the frequency, power, antenna height or 
directivity, or location of such a station within the area boarded by 
39 deg.15' N. on the north, 78 deg.30' W. on the east, 37 deg.30' N. on 
the south, and 80 deg.30' W. on the west must at the time of filing 
such application with the Commission, simultaneously notify the 
Director, National Radio Astronomy Observatory, Post Office Box No. 2, 
Green Bank, W. Va. 24944, in writing, of the technical particulars of 
the proposed station. Such notification must include the geographical 
coordinates of the antenna, antenna height, antenna directivity if any, 
proposed frequency, type of emission and power. In addition, the 
applicant must 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 twenty (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.
    (b) Protection for Table Mountain Radio Receiving Zone, Boulder 
County, Colorado. Applicants for a station authorization to operate in 
the vicinity of Boulder County, Colorado under this part are advised to 
give due consideration, prior to filing applications, to the need to 
protect the Table Mountain Radio Receiving Zone from harmful 
interference. These are the research laboratories of the Department of 
Commerce, Boulder County, Colorado. To prevent degradation of the 
present ambient radio signal level at the site, the Department of 
Commerce seeks to ensure that the field strengths of any radiated 
signals (excluding reflected signals) received on this 1800 acre site 
(in the vicinity of coordinates 40 deg.07'50'' N. Latitude, 
105 deg.14'40'' W. Longitude), resulting from new assignments or from 
the modification or relocation of existing facilities do not exceed 1 
mV/m in the authorized bandwidth of service. (A field strength of 1 mV/
m is equivalent to a power flux density of 85.8 dBW/M\2\ assuming a 
free-space characteristic impedance of 376.7 ohms.)
    (1) Advance consultation is recommended particularly for those 
applicants who have no reliable data which indicates whether the field 
strength or power flux density figures would be exceeded by their 
proposed radio facilities. In such instances, the following is a 
suggested guide for determining whether coordination is recommended:
    (i) All stations within 2.4 km;
    (ii) Stations within 4.8 km with 50 watts or more effective 
radiated power (ERP) in the primary plane of polarization in the 
azimuthal direction of the Table Mountain Receiving Zone;
    (iii) Stations within 16 km with 1 kW or more ERP in the primary 
plane of polarization in the azimuthal direction of the Table Mountain 
Receiving Zone; or
    (iv) Stations within 80 km with 25 kW or more ERP in the primary 
plane of polarization in the azimuthal direction of the Table Mountain 
Receiving Zone.
    (2) 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.
    (3) 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,

[[Page 26703]]

delivers a signal at the site in excess of the field strength specified 
herein.
    (c) Protection for Federal Communications Commission monitoring 
stations:
    (1) Applicants in the vicinity of an FCC monitoring station for a 
radio station authorization to operate new transmitting facilities or 
changed transmitting facilities which would increase the field strength 
produced over the monitoring station over that previously authorized 
are advised to give consideration, prior to filing applications, to the 
possible need to protect the FCC stations from harmful interference. 
Geographical coordinates of the facilities which require protection are 
listed in Sec. 0.121(c) of this chapter. Applications for stations 
(except mobile stations) which will produce on any frequency a direct 
wave fundamental field strength of greater than 10 mV/m in the 
authorized bandwidth of service (-65.8 dBW/m2 power flux density 
assuming a free space characteristic impedance of 120 ohms) at the 
referenced coordinates, may be examined to determine 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 indicated coordinates, a clause protecting the monitoring station 
may be added to the station authorization.
    (2) In the event that calculated value of expected field exceeds 10 
mV/m (-65.8 dBW/m2) 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. Prospective applicants may communicate 
with: Chief, Compliance and Information Bureau, Federal Communications 
Commission, Washington, DC 20554, Telephone (202) 418-1100.
    (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 2.4 kilometers;
    (ii) Stations within 4.8 kilometers with 50 watts or more average 
effective radiated power (ERP) in the primary plane of polarization in 
the azimuthal direction of the Monitoring Stations;
    (iii) Stations within 16 kilometers with 1 kW or more average ERP 
in the primary plane of polarization in the azimuthal direction of the 
Monitoring Station; or
    (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 (c)(2) and (c)(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.


Sec. 101.125  Temporary fixed antenna height restrictions.

    The overall antenna structure heights employed by mobile stations 
in the Local Television Transmission Service and by stations authorized 
to operate at temporary fixed locations may not exceed the height 
criteria set forth in Sec. 17.7 of this chapter, unless in each 
instance, authorization for use of a specific maximum antenna height 
(above ground and above mean sea level) for each location has been 
obtained from the Commission prior to erection of the antenna. Requests 
for such authorization must show the inclusive dates of the proposed 
operation. (Complete information as to rules concerning the 
construction, marking and lighting of antenna structures is contained 
in part 17 of this chapter.)


Sec. 101.127  Topographical data.

    Determining the location and height above sea level of the antenna 
site, the elevation or contour intervals must be taken from United 
States Geological Survey Topographic Quadrangle Maps, United States 
Army Corps of Engineers maps or Tennessee Valley Authority maps, 
whichever is the latest, for all areas for which such maps are 
available. If such maps are not published for the area in question, the 
next best topographic information should be used. Topographic data may 
sometimes be obtained from State and municipal agencies. Data from 
Sectional Aeronautical Charts (including bench marks) or railroad depot 
elevations and highway elevations from road maps may be used where no 
better information is available. In cases where limited topographic 
data is available, use may be made of an altimeter in a car driven 
along roads extending generally radially from the transmitter site. If 
it appears necessary, additional data may be requested. United States 
Geological Survey Topographic Quadrangle Maps may be obtained from the 
Department of the Interior, Geological Survey, Washington, DC 20242. 
Sectional Aeronautical Charts are available from the Department of 
Commerce, Coast and Geodetic Survey, Washington, DC 20230.


Sec. 101.129  Transmitter location.

    (a) The applicant must determine, prior to filing an application 
for a radio station authorization, that the antenna site specified 
therein is adequate to render the service proposed. In cases of 
questionable antenna locations, it is desirable to conduct propagation 
tests to indicate the field intensity which may be expected in the 
principal areas or at the fixed points of communication to be served, 
particularly where severe shadow problems may be expected. In 
considering applications proposing the use of such locations, the 
Commission may require site survey tests to be made pursuant to a 
developmental authorization in the particular service concerned. In 
such cases, propagation tests should be conducted in accordance with 
recognized engineering methods and should be made with a transmitting 
antenna simulating, as near as possible, the proposed antenna 
installation. Full data obtained from such surveys and its analysis, 
including a description of the methods used and the name, address and 
qualifications of the engineer making the survey, must be supplied to 
the Commission.
    (b) Antenna structures should be so located and constructed as to 
avoid making them hazardous to air navigation. (See part 17 of this 
chapter for provisions relating to antenna structures.) Such 
installation must be maintained in good structural condition together 
with any required painting or lighting.


Sec. 101.131  Transmitter construction and installation.

    (a) The equipment at the operating and transmitting positions must 
be so installed and protected that it is not accessible to, or capable 
of being operated by, persons other than those duly authorized by the 
licensee.
    (b) In any case where the maximum modulating frequency of a 
transmitter is prescribed by the Commission, the transmitter must be 
equipped with a low-pass or band-pass modulation filter

[[Page 26704]]

of suitable performance characteristics. In those cases where a 
modulation limiter is employed, the modulation filter must be installed 
between the transmitter stage in which limiting is effected and the 
modulated stage of the transmitter.
    (c) Each transmitter employed in these services must be equipped 
with an appropriately labeled pilot lamp or meter which will provide 
continuous visual indication at the transmitter when its control 
circuits have been placed in a condition to activate the transmitter. 
In addition, facilities must be provided at each transmitter to permit 
the transmitter to be turned on and off independently of any remote 
control circuits associated therewith.
    (d) At each transmitter control point the following facilities must 
be installed:
    (1) A carrier operated device which will provide continuous visual 
indication when the transmitter is radiating, or, in lieu thereof, a 
pilot lamp or meter which will provide continuous visual indication 
when the transmitter control circuits have been placed in a condition 
to activate the transmitter; and
    (2) Facilities which will permit the operator to turn transmitter 
carrier on and off at will.
    (e) Transmitter control circuits from any control point must be so 
installed that grounding or shorting any line in the control circuit 
will not cause the transmitter to radiate: provided, however, That this 
provision will not be applicable to control circuits of stations which 
normally operate with continuous radiation or to control circuits which 
are under the effective operational control of responsible operating 
personnel 24 hours per day.


Sec. 101.133  Limitations on use of transmitters.

    (a) Transmitters licensed for operation in Common Carrier services 
may be concurrently licensed or used for non-common carrier 
communication purposes. Mobile units may be concurrently licensed or 
used for non-common carrier communication purposes provided that the 
transmitter is type-accepted for use in each service.
    (b) Private operational fixed point-to-point microwave stations 
authorized in this service may communicate with associated operational-
fixed stations and fixed receivers and with units of associated 
stations in the mobile service licensed under Private Radio Service 
rule parts. In addition, intercommunication is permitted with other 
licensed stations and with U.S. Government stations in those cases 
which require cooperation or coordination of activities or when 
cooperative use arrangements in accordance with Sec. 101.135 are 
contemplated; provided, however, that where communication is desired 
with stations authorized to operate under the authority of a foreign 
jurisdiction, prior approval of this Commission must be obtained; And 
provided further, That the authority under which such other stations 
operate does not prohibit the intercommunication.
    (c) Two or more persons or governmental entities eligible for 
private operational fixed point-to-point microwave licenses may use the 
same transmitting equipment under the following terms and conditions:
    (1) Each licensee complies with the general operating requirements 
set out in this part;
    (2) Each licensee is eligible for the frequency(ies) on which the 
facility operates; and
    (3) Each licensee must have the ability to access the 
transmitter(s) that it is authorized to operate under the multiple 
licensing arrangement.


Sec. 101.135  Shared use of radio stations and the offering of private 
carrier service.

    Licensees of Private Operational Fixed Point-to-Point Microwave 
radio stations may share the use of their facilities on a non-profit 
basis or may offer service on a for-profit private carrier basis, 
subject to the following conditions and limitations:
    (a) Persons or governmental entities licensed to operate radio 
systems on any of the private radio frequencies set out in Sec. 101.101 
may share such systems with, or provide private carrier service to, any 
eligible for licensing under this part, regardless of individual 
eligibility restrictions, provided that the communications being 
carried are permissible under Sec. 101.603. In addition, persons or 
governmental entities licensed to operate low power systems under the 
provisions of Sec. 101.147(r)(10) may share such systems with, or 
provide private carrier services to, Federal Government entities, 
provided the communications carried are permissible under Sec. 101.603;
    (b) The licensee must maintain access to and control over all 
facilities authorized under its license;
    (c) All sharing and private carrier arrangements must be conducted 
pursuant to a written agreement to be kept as part of the station 
records; and
    (d) The licensee must keep an up-to-date list of system sharers and 
private carrier subscribers and the basis of their eligibility under 
this part. Such records must be kept current and must be made available 
upon request for inspection by the Commission.


Sec. 101.137  Interconnection of private operational fixed point-to-
point microwave stations.

    Private operational fixed point-to-point microwave stations may be 
interconnected with facilities of common carriers subject to applicable 
tariffs.


Sec. 101.139  Authorization of transmitters.

    (a) Except for transmitters used at developmental stations or for 
fixed point-to-point operation pursuant to subparts H and I of this 
part, each transmitter must be a type which has been type accepted by 
the Commission for use under the applicable rules of this part. 
Transmitters used in the private operational fixed and common carrier 
fixed point-to-point microwave services under subparts H and I of this 
part must be of a type that has been either notified or type accepted 
by the Commission (see Sec. 2.904(d) of this chapter). Effective March 
5, 1984, only grants of notification will be issued for transmitters 
used exclusively for fixed point-to-point operation. Transmitters 
designed for use in the 31.0 to 31.3 GHz band will be authorized under 
the notification procedure.
    (b) Any manufacturer of a transmitter to be produced for use under 
the rules of this part may request type acceptance or notification by 
following the applicable procedures set forth in part 2 of this 
chapter. Type accepted and notified transmitters are included in the 
Commission's Radio Equipment List. Copies of this list are available 
for inspection at the Commission's office in Washington, DC and at each 
of its field offices.
    (c) Type acceptance or notification for an individual transmitter 
may also be requested by an applicant for a station authorization, 
pursuant to the procedures set forth in part 2 of this chapter. An 
individual transmitter will not normally be included in the Radio 
Equipment List but will be enumerated on the station authorization.
    (d) A transmitter presently shown on an instrument of 
authorization, which operates on an assigned frequency in the 890-940 
MHz band and has not been type accepted, may continue to be used by the 
licensee without type acceptance provided such transmitter continues 
otherwise to comply with the applicable rules and regulations of the 
Commission.
    (e) Type acceptance or notification is not required for portable 
transmitters operating with peak output power not greater than 250 mW. 
If operation of

[[Page 26705]]

such equipment causes harmful interference the FCC may, at its 
discretion, require the licensee to take such corrective action as is 
necessary to eliminate the interference.
    (f) After July 15, 1996, the manufacture (except for export) or 
importation of equipment employing digital modulation techniques in the 
3700-4200, 5925-6425, 6525-6875, 10,550-10,680 and 10,700-11,700 MHz 
bands must meet the minimum payload capacity requirements of 
Sec. 101.141.


Sec. 101.141  Microwave modulation.

    (a) Microwave transmitters employing digital modulation techniques 
and operating below 19.7 GHz must, with appropriate multiplex 
equipment, comply with the following additional requirements:
    (1) The bit rate, in bits per second, must be equal to or greater 
than the bandwidth specified by the emission designator in Hertz (e.g., 
to be acceptable, equipment transmitting at a 20 Mb/s rate must not 
require a bandwidth of greater than 20 MHz), except the bandwidth used 
to calculate the minimum rate may not include any authorized guard 
band.

    Note to (a)(1): Systems authorized prior to December 1, 1988, 
may install equipment after that date with no minimum bit rate.

    (2) Equipment to be used for voice transmission placed in service, 
authorized, or applied for on or before June 1, 1997 in the 2110 to 
2130 and 2160 to 2180 MHz bands must be capable of satisfactory 
operation within the authorized bandwidth to encode at least 96 voice 
channels. Equipment placed in service, authorized, or applied for on or 
before June 1, 1997 in the 3700-4200, 5925-6425 (30 MHz bandwidth), and 
10,700-11,700 MHz (30 and 40 MHz bandwidths) bands must be capable of 
satisfactory operation within the authorized bandwidth to encode at 
least 1152 voice channels. These required loading levels may be reduced 
by a factor of 1/N provided that N transmitters may be operated 
satisfactorily, over the same radio path, within an authorized 
bandwidth less than, or equal to, the maximum authorizable bandwidth 
(e.g., the 1152 channel requirement may be reduced to 576 if two 
transmitters can be satisfactorily operated over the same path within 
the maximum bandwidth). Where type accepted equipment is designed to 
operate on the same frequency in a cross polarized configuration to 
meet the above capacity requirements, the Commission will require, at 
the time additional transmitters are authorized, that both 
polarizations of a frequency be used before a new frequency assignment 
is made, unless a single transmitter installation was found to be 
justified by the Commission at the time it authorized the first 
transmitter.
    (3) The following capacity and loading requirements must be met for 
equipment applied for, authorized, and placed in service after June 1, 
1997 in the 3700-4200 MHz (4 GHz), 5925-6425 and 6525-6875 MHz (6 GHz), 
10,550-10,680 MHz (10 GHz), and 10,700-11,700 MHz (11 GHz) bands:

\3\ This loading requirement must be met within 30 months of licensing. 
  If two transmitters simultaneously operate on the same frequency over 
  the same path, the requirement is reduced to 25 percent.              

    (4) If a transmitter is authorized to operate in a bandwidth that 
is not listed in paragraph (a)(3) of this section, it must meet the 
minimum payload capacity and traffic loading requirements of the next 
largest channel bandwidth listed in the table; e.g., if the authorized 
bandwidth is 3.5 MHz, the minimum payload capacity must be 12.3 Mbits/
s.
    (5) Transmitters carrying digital motion video motion material are 
exempt from the requirements specified in paragraphs (a)(2) and (a)(3) 
of this section, provided that at least 50 percent of the payload is 
digital video motion material and the minimum bit rate specified in 
paragraph (a)(1) of this section is met. In the 6, 10, and 11 GHz 
bands, concatenation of multiple contiguous channels is permitted for 
channels of equal bandwidth on center frequencies, provided no other 
channels are available and the minimum payload capacity requirements 
are met.
    (6) Digital systems using bandwidths of 10 MHz or larger will be 
considered 50 percent loaded when the following condition is met: at 
least 50 percent of their total DS-1 capacity is being used. A DS-1 
channel is being used when it has been connected to a DS-0/DS-1 
multiplexer. For non-DS-0 services, such as, but not limited to, video 
or broadband data transmission, the next largest DS-1 equivalent will 
be considered for the computation of a loading percentage.
    (7) For digital systems, minimum payload capacities shall be 
expressed in numbers of DS-1s, DS-3s or STS-1s. The payload capacity 
required by the Commission shall correspond to commercially available 
equipment.

[[Page 26706]]

    (b) For purposes of compliance with the emission limitation 
requirements of Sec. 101.111(a)(2) and the requirements of paragraph 
(a) of this section, digital modulation techniques are considered as 
being employed when digital modulation occupies 50 percent or more to 
the total peak frequency deviation of a transmitted radio frequency 
carrier. The total peak frequency deviation will be determined by 
adding the deviation produced by the digital modulation signal and the 
deviation produced by any frequency division multiplex (FDM) modulation 
used. The deviation (D) produced by the FDM signal must be determined 
in accordance with Sec. 2.202(f) of this chapter.
    (c) Analog Modulation. Except for video transmission, an 
application for an initial working channel for a given route will not 
be accepted for filing where the anticipated loading (within five years 
for voice, or other period subject to reasonable projection) is less 
than the minimum specified for the following frequency bands. Absent 
extraordinary circumstances, applications proposing additional 
frequencies over existing routes will not be granted unless it is shown 
that the traffic load will shortly exhaust the capacity of the existing 
equipment. Where no construction of radio facilities is requested, 
licensees must submit this evidence with their filing of any necessary 
authority required pursuant to section 214 of the Communications Act 
and part 63 of this chapter.

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

    (b) For paths shorter than those specified in the Table, the EIRP 
shall not exceed the value derived from the following equation:

EIRP = MAX EIRP--40*log(A/B) dBW

Where:
EIRP=Equivalent isotropically radiated power in dBW.
A=Minimum path length from the Table for the frequency band in 
kilometers.
B=The actual path length in kilometers.

    Note to paragraph (b): For transmitters using Automatic Transmit 
Power Control, EIRP that corresponds to the maximum transmitter 
power must satisfy this requirement.

    (c) Upon an appropriate technical showing, applicants and licensees 
unable to meet the minimum path length requirement may be granted an 
exception to these requirements.

    Note to paragraph (c): Links authorized prior to April 1, 1987, 
need not comply with this requirement.


Sec. 101.145  Interference to geostationary-satellites.

    These limitations are necessary to minimize the probability of 
harmful interference to reception in the bands 2655-2690 MHz, 5925-6875 
MHz, and 12.7-12.75 GHz on board geostationary-space stations in the 
fixed-satellite service.
    (a) Stations authorized prior to July 1, 1976 in the band 2655-2690 
MHz, which exceed the power levels in paragraphs (a) and (b) of this 
section are permitted to operate indefinitely, provided that the 
operations of such stations does not result in harmful interference to 
reception in these band on board geostationary space stations.
    (b) 2655 to 2690 MHz and 5925 to 6875 MHz. No directional 
transmitting antenna utilized by a fixed station operating in these 
bands may be aimed within 2 degrees of the geostationary-satellite 
orbit, taking into account atmospheric refraction. However, exception 
may be made in unusual circumstances upon a showing that there is no 
reasonable alternative to the transmission path proposed. If there is 
no evidence that such exception would cause possible harmful 
interference to an authorized satellite system, said transmission path 
may be authorized on waiver basis where the maximum value of the 
equivalent isotropically radiated power (EIRP) does not exceed:
    (1) +47 dBW for any antenna beam directed within 0.5 degrees of the 
stationary satellite orbit; or
    (2) +47 to +55 dBW, on a linear decibel scale (8 dB per degree) for 
any antenna beam directed between 0.5 degrees and 1.5 degrees of the 
stationary orbit.
    (c) 12.7 to 12.75 GHz. No directional transmitting antenna utilized 
by a fixed station operating in this band may be aimed within 1.5 
degrees of the geostationary-satellite orbit, taking into account 
atmospheric refraction. However, exception may be made in unusual 
circumstances upon a showing that there is no reasonable alternative to 
the transmission path proposed. If there is no evidence that such 
exception would cause possible harmful interference to an authorized 
satellite system, said transmission path may be authorized on waiver 
basis where the maximum value of the equivalent isotropically radiated 
power (EIRP) does not exceed +45 dBW for any antenna beam directed 
within 1.5 degrees of the stationary satellite orbit.

between a master station and remote stations. Each master station 
operating on these frequencies is required to serve a minimum of four 
separate active remote stations. Ancillary one-way communications on 
paired frequencies are permitted on a case-by-case basis. Ancillary 
communications between interrelated master stations are permitted on a 
secondary basis. The normal channel bandwidth assigned will be 12.5 
kHz. Upon adequate justification, however, channels with bandwidths up 
to 50 kHz may be authorized. Tables 2, 4, and 6 list frequencies with 
25 kHz bandwidth channels. When licensed for a larger bandwidth, the 
system still is required to use equipment that meets the 
0.00015 percent tolerance requirement. (See Sec. 101.107). 
Any bandwidth (12.5 kHz, 25 kHz or greater) authorized in accordance 
with this section may be subdivided into narrower bandwidths to create 
additional (or sub) frequencies without the need to specify each 
discrete frequency within the specific bandwidth. Equipment that is 
used to create additional frequencies by narrowing bandwidth (whether 
authorized for a 12.5 kHz, 25 kHz or greater bandwidth) will be 
required to meet, at a minimum, the 0.00015 percent 
tolerance requirement so that all subfrequencies will be within the 
emission mask. When using subfrequencies, licensees are subject to the 
construction requirement of one master and four remotes per authorized 
bandwidth (12.5 kHz, 25 kHz or greater. Systems licensed for 
frequencies in these MAS bands prior to August 1, 1975, may continue to 
operate as authorized until June 11, 1996, at which time they must 
comply with current MAS operations based on the 12.5 KHz channelization 
set forth in this

paragraph. Systems licensed between August 1, 1975, and January 1, 
1981, inclusive, are required to comply with the grandfathered 25 kHz 
standard bandwidth and channelization requirements set forth in this 
paragraph. Systems originally licensed after January 1, 1981, and on or 
before May 11, 1988, with bandwidths of 25 kHz and above, will be 
grandfathered indefinitely. (1) General Access Pool: Frequencies listed 
in this paragraph are available to all persons eligible under this part 
for use in multiple address radio systems. Except as noted, however, 
the frequencies may be used by eligibles in the Power Radio Service 
only if the frequencies in paragraph (b) (2) of this section are 
exhausted in the particular geographic area. The frequencies are also 
available for shared use by part 22 Public Land Mobile Service users if 
frequencies listed in Sec. 22.50(g) of this chapter are exhausted in 
the particular geographic area. Applications for use of these 
frequencies under part 22 of this chapter are subject to part 101 
requirements.

    (e) 2150-2160 MHz: Specific frequency of operation to be set forth 
in authorization. Omnidirectional transmission only may be authorized, 
subject to providing protection from harmful interference to previously 
authorized stations in this service and in other services sharing this 
band.
    (f) 2450-2500 MHz:
    (1) This band is shared with other communications services and is 
not subject to protection from interference from industrial, 
scientific, and medical devices operating on 2450 MHz.
    (2) Stations licensed in this band under this part prior to March 
1, 1996, are grandfathered and may continue their authorized 
operations. Stations licensed in the 2483.5-2500 MHz portion of the 
band as of July 25, 1985, or on a subsequent date as a result of 
submitting an application on or before July 25, 1985, are 
grandfathered, and may continue operations, subject only to license 
renewal, on a co-primary basis with the Radiodetermination Satellite 
Service.
    (3) 625 KHz bandwidth channels. The normal bandwidth authorized 
will be 625 KHz. Upon adequate justification, additional contiguous 
channels may be authorized to provide up to a 2500 KHz bandwidth.

    (p) 12,000-12700 MHz: The Commission has allocated the 12.2-12.7 
GHz band for use by the broadcasting-satellite service. Private 
operational fixed point-to-point microwave stations authorized after 
September 9, 1983, will be licensed on a noninterference basis and are 
required to make any and all adjustments necessary to prevent 
interference to operating domestic broadcasting-satellite systems. 
Notwithstanding any other provisions, no private operational fixed 
point-to-point microwave stations are permitted to cause interference 
to broadcasting-satellite stations of other countries operating in 
accordance with the Region 2 plan for the broadcasting-satellite 
service established at the 1983 WARC.
    (q) Special provisions for low power, limited coverage systems in 
the band segments 12.2 12.7 GHz. Notwithstanding any contrary 
provisions in this part the frequency pairs 12.220/12.460 GHz, 12.260/
12.500 GHz, 12.300/12.540 GHz and 12.340/12.580 GHz may be authorized 
for low power, limited coverage systems subject to the following 
provisions:
    (1) Maximum equivalent isotropically radiated power (EIRP) shall be 
55 dBm;
    (2) The rated transmitter output power shall not exceed 0.500 
watts;
    (3) Frequency tolerance shall be maintained to within 0.01 percent 
of the assigned frequency;
    (4) Maximum beamwidth not to exceed 4 degrees. However, the 
sidelobe suppression criteria contained in Sec. 101.115 of this part 
shall not apply, except that a minimum front-to-back ratio of 38 dB 
shall apply;
    (5) Upon showing of need, a maximum bandwidth of 12 MHz may be 
authorized per frequency assigned;
    (6) Radio systems authorized under the provisions of this section 
shall have no more than three hops in tandem, except upon showing of 
need, but in any event the maximum tandem length shall not exceed 40 km 
(25 miles);
    (7) Interfering signals at the receiver antenna terminals of 
stations authorized under this section shall not exceed -90 dBm and -70 
dBm respectively, for co-channel and adjacent channel interfering 
signals, and
    (8) Stations authorized under the provisions of this section shall 
provide the protection from interference specified in Sec. 101.105 to 
stations operating in accordance with the provisions of this part.
    (r) 17,700 to 19,700 MHz: Applicants may use either a two-way link 
or one frequency of a frequency pair for a one-way link and must 
coordinate proposed operations pursuant to the procedures required in 
Sec. 101.103. (Note, however, that stations authorized as of September 
9, 1983, to use frequencies in the band 17.7-19.7 GHz may, upon proper 
application, continue to be authorized for such operations.)

    Note to (u): These channels are assigned for use within a 
rectangular service area to be described in the application by the 
maximum and minimum latitudes and longitudes. Such service area must 
be as small as practical consistent with the local service 
requirements of the carrier. These frequency plans may be subdivided 
as desired by the licensee and used within the service area as 
desired without further authorization subject to the terms and 
conditions set forth in Sec. 101.149. These frequencies may be 
assigned only where it is shown that the applicant will have 
reasonable projected requirements for a multiplicity of service 
points or transmission paths within the area.
