                               EXPLANATION

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

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

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

LEGAL STATUS

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

HOW TO USE THE CODE OF FEDERAL REGULATIONS

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

EFFECTIVE AND EXPIRATION DATES

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

OMB CONTROL NUMBERS

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

[[Page vi]]

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

PAST PROVISIONS OF THE CODE

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

``[RESERVED]'' TERMINOLOGY

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

INCORPORATION BY REFERENCE

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

CFR INDEXES AND TABULAR GUIDES

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

[[Page vii]]

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

REPUBLICATION OF MATERIAL

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

    Distress signal. The distress signal is a digital selective call 
using an internationally recognized distress call format in the bands 
used for terrestrial communication or an internationally recognized 
distress message format, in which case it is relayed through space 
stations, which indicates that a person, ship, aircraft, or other 
vehicle is threatened by grave and imminent danger and requests 
immediate assistance.
    (1) In radiotelephony, the international distress signal consists of 
the enunciation of the word ``Mayday'', pronounced as the French 
expression ``m'aider''. In case of distress, transmission of this 
particular signal is intended to ensure recognition of a radiotelephone 
distress call by stations of any nationality.
    (2) For GMDSS, distress alerts result in an audible alarm and visual 
indication that a ship or person is threatened by grave and imminent 
danger and requests immediate assistance. These automatic systems 
contain sufficient information in the distress alert message to identify 
the vessel, prepare to assist and begin a search. However, except when 
transmitted via satellite EPIRB, the distress alert is just the initial 
call for help. Communication between the vessel or person in distress 
and the Rescue Coordination Center (RCC) or ship assisting should always 
follow.

technical characteristics.
    (10) Coastal Waters Local Channel. Same as (7) except for technical 
characteristics.
    (c) Technical characteristics. On the west coast, technical 
characteristics of public correspondence stations will be as follows:
    (1) Inland Waters Primary and Supplementary Channels. The effective 
radiated power (ERP) must not exceed 60 watts. Antenna height must not 
exceed 152 meters (500 feet) above mean sea level (AMSL) with the 
exceptions noted in paragraph (d)(5) of this section.
    (2) Inland Waters Local Channel. ERP must not exceed 8 watts with an 
antenna height of no more than 15 meters (50 feet) AMSL or the ERP must 
not exceed 2 watts with an antenna height of no more than 30 meters (100 
feet) AMSL.
    (3) Coastal Waters Primary and Supplementary Channels. ERP must not 
exceed 125 watts with no antenna restrictions.
    (4) Coastal Waters Local Channel. ERP must not exceed 10 watts with 
a maximum antenna height of 76 meters (250 feet) AMSL.
    (5) Harmful interference will be determined and resolved using the 
definition and procedures of the ITU Radio Regulations.
    (6) To keep the ERP and antenna elevations at a minimum and to limit 
coverage to the desired areas, an informal application may be filed for 
special temporary authority in accordance with Sec. Sec.  1.41 and 1.931 
of this chapter to conduct a field survey to obtain necessary data for 
informal application. Such data may accompany the application and be 
used in lieu of theoretical calculations as required in subpart P of 
this part. The Seattle FCC District Office must be notified in advance 
of scheduled tests.
    (d) Canada/U.S.A. channeling arrangement for West Coast VHF maritime 
mobile public correspondence. (1) The provisions of the Canada/U.S. 
channeling arrangement apply to waters of the State of Washington and of 
the Province of British Columbia within the coordination boundaries of 
``Arrangement A'' of the Canada/U.S.A. Frequency Coordination Agreement 
above 30 MHz. In addition, all inland waters as far south as Olympia are 
to be included. A map of these waters is contained in paragraph (d)(6) 
of this section, Figure 1.
    (2) The channeling arrangement applies to the following VHF public 
correspondence channels: Channels 24, 84, 25, 85, 26, 86, 27, 87 and 28.
    (3) Public correspondence stations may be established by either 
country in accordance with the provisions of the arrangements. However, 
there must be an exchange of information prior to the establishment of 
new stations or a change in technical parameters of existing stations. 
Any channel except that used as primary or supplementary channel in a 
given sector is available for use as a local channel in that sector. 
Local channels are not protected from interference caused by primary or 
supplementary channels in adjacent sectors if these stations are in 
compliance with this section.
    (4) Preliminary local Canadian/U.S. coordination is required for all 
applications at variance with this section. This coordination will be in 
accordance with the provisions of Arrangement ``A'' of the Canada/U.S. 
Frequency Coordination Agreement over 30 MHz.

[[Page 26]]

Stations at variance with the arrangement are not protected from 
interference and must not cause interference to existing or future 
stations which are in accordance with the agreement.
    (5) The agreed channeling arrangements for the west coast are as 
follows:

Sec.  80.60  Partitioned licenses and disaggregated spectrum.

    (a) Except as specified in Sec.  20.15(c) of this chapter with 
respect to commercial mobile radio service providers, charges must not 
be made for service of:
    (1) VHF Public Coast area licensees, see Sec.  80.371(c)(1)(ii), may 
partition their geographic service area or disaggregate their spectrum 
pursuant to the procedures set forth in this section.
    (2) AMTS geographic area licensees, see Sec.  80.385(a)(3), may 
partition their geographic service area or disaggregate their spectrum 
pursuant to the procedures set forth in this section. Site-based AMTS 
public coast station licensees may partition their license or 
disaggregate their spectrum pursuant to the procedures set forth in this 
section, provided that the partitionee or disaggregatee's predicted 38 
dBu signal level contour does not extend beyond the partitioner or 
disaggregator's predicted 38 dBu signal level contour. The predicted 38 
dBu signal level contours shall be calculated using the F(50, 50) field 
strength chart for Channels 7-13 in Sec.  73.699 (Fig. 10) of this 
chapter, with a 9 dB correction for antenna height differential.
    (3) Nationwide or multi-region LF, MF, and HF public coast station 
licensees, see Sec. Sec.  80.357(b)(1), 80.361(a), 80.363(a)(2), 
80.371(b), and 80.374, may partition their spectrum pursuant to the 
procedures set forth in this section, except that frequencies or 
frequency pairs licensed to more than one licensee as of March 13, 2002 
may be partitioned only by the earliest licensee, and only on the 
condition that the

[[Page 31]]

partitionee shall operate on a secondary, non-interference basis to 
stations licensed as of March 13, 2002 other than the earliest licensee. 
Coordination with government users is required for partitioning of 
spectrum the licensing of which is subject to coordination with 
government users.
    (b) Technical standards--(1) Partitioning. In the case of 
partitioning, all requests for authorization for partial assignment of a 
license must include, as an attachment, a description of the partitioned 
service area. The partitioned service area shall be defined by 
coordinate points at every 3 degrees along the partitioned service area 
unless an FCC-recognized service area is utilized (e.g., Metropolitan 
Service Area, Rural Service Area, or Economic Area) or county lines are 
used. The geographic coordinates must be specified in degrees, minutes, 
and seconds to the nearest second of latitude and longitude, and must be 
based upon the 1983 North American Datum (NAD83). In a case where an 
FCC-recognized service area or county lines are utilized, applicants 
need only list the specific area(s) (through use of FCC designations or 
county names) that constitute the partitioned area.
    (2) Disaggregation. VHF (156-162 MHz) spectrum may only be 
disaggregated according to frequency pairs. AMTS spectrum may be 
disaggregated in any amount.
    (3) Combined partitioning and disaggregation. The Commission will 
consider requests for partial assignment of licenses that propose 
combinations of partitioning and disaggregation.
    (c) License term. The license term for a partitioned license area 
and for disaggregated spectrum shall be the remainder of the original 
licensee's term as provided for in Sec.  80.25 of this part.
    (d) Partitioning and disaggregation construction requirements for 
site-based AMTS, and nationwide or multi-region LF, MF, and HF public 
coast. Parties seeking to acquire a partitioned license or disaggregated 
spectrum from a site-based AMTS, or nationwide or multi-region LF, MF, 
and HF public coast licensee will be required to construct and commence 
``service to subscribers'' in all facilities acquired through such 
transactions within the original construction deadline for each facility 
as set forth in Sec.  80.49. Failure to meet the individual construction 
deadline will result in the automatic termination of the facility's 
authorization.

such systems from offering the complete order of priority.

[68 FR 46960, Aug. 7, 2003]



Sec.  80.92  Prevention of interference.

    (a) The station operator must determine that the frequency is not in 
use by monitoring the frequency before transmitting, except for 
transmission of signals of distress.
    (b) When a radio communication causes interference to a 
communication which is already in progress, the interfering station must 
cease transmitting at the request of either party to the existing 
communication. As between nondistress traffic seeking to commence use of 
a frequency, the priority is established under Sec.  80.91.
    (c) Except in cases of distress, communications between ship 
stations or between ship and aircraft stations must not interfere with 
public coast stations. The ship or aircraft stations which cause 
interference must stop transmitting or change frequency upon the first 
request of the affected coast station.



Sec.  80.93  Hours of service.

    (a) All stations. All stations whose hours of service are not 
continuous must not suspend operation before having concluded all

Sec.  80.96  Maintenance tests.

    Stations are authorized to engage in test transmissions necessary 
for maintenance of the station. Test transmissions must conform to 
appropriate test operating procedures.



Sec.  80.97  Radiotelegraph operating procedures.

    This section applies to ships and coast stations authorized to 
transmit in the band 405-525 kHz.
    (a) Except for the transmission of distress or urgency signals, all 
transmissions must cease within the band 485-515 kHz during each 500 kHz 
silence period.
    (b) Stations transmitting telegraphy must use the service 
abbreviations (``Q'' code) listed in Appendix 14 to the Radio 
Regulations.
    (c) The call consists of:
    (1) The call sign of the station called, not more than twice; the 
word ``DE'' and the call sign of the calling station, not more than 
twice; if useful, the frequency on which the called station should 
reply; and the letter ``K''.
    (2) If the call is transmitted twice at an interval of not less than 
one minute, it must not be repeated until after an interval of three 
minutes.
    (d) The reply to calls consists of: The call sign of the calling 
station, not

assigned frequency. Emissions must not cause harmful interference. When 
radiation is necessary the radiotelegraph testing procedure described in 
this paragraph must be followed:
    (a) The operator must not interfere with transmissions in progress.
    (b) The operator must transmit ``IE'' (two dots, space, one dot) on 
the test frequency as a warning that test emissions are about to be 
made.
    (c) If any station transmits ``AS'' (wait), testing must be 
suspended. When transmission of ``IE'' is resumed and no response is 
heard, the test may proceed.
    (d) Test signals composed of a series of ``VVV'' having a duration 
of not more than ten seconds, followed by the call sign of the testing 
station will be transmitted. The call sign must be sent clearly at a 
speed of approximately 10 words per minute. This test transmission must 
not be repeated until a period of at least one minute has elapsed.

[69 FR 64671, Nov. 8, 2004]



Sec.  80.99  Radiotelegraph station identification.

    This section applies to coast, ship and survival craft stations 
authorized to transmit in the band 405-525 kHz.
    (a) The station transmitting radiotelegraph emissions must be 
identified by its call sign. The call sign must be transmitted with the 
telegraphy emission normally used by the station. The call sign must be 
transmitted at 20 minute intervals when transmission is sustained for 
more than 20 minutes. When a ship station is exchanging public 
correspondence communications, the identification may be deferred until 
completion of each communication with any other station.
    (b) The requirements of this section do not apply to survival craft 
stations when transmitting distress signals automatically or when 
operating on 121.500 MHz for radiobeacon purposes.
    (c) Emergency position indicating radiobeacon stations do not 
require identification.



Sec.  80.100  Morse code requirement.

    The code employed for telegraphy must be the Morse code specified in 
the Telegraph Regulations annexed to the International Telecommunication 
Convention. Pertinent extracts from the Telegraph Regulations are 
contained in the ``Manual for Use by the Maritime Mobile and Maritime 
Mobile-Satellite Services'' published by the International 
Telecommunication Union.



Sec.  80.101  Radiotelephone testing procedures.

    This section is applicable to all stations using telephony except 
where otherwise specified.
    (a) Station licensees must not cause harmful interference. When 
radiation is necessary or unavoidable, the testing procedure described 
below must be followed:
    (1) The operator must not interfere with transmissions in progress.
    (2) The testing station's call sign, followed by the word ``test'', 
must be announced on the radio-channel being used for the test.
    (3) If any station responds ``wait'', the test must be suspended for 
a minimum of 30 seconds, then repeat the call sign followed by the word 
``test'' and listen again for a response. To continue the test, the 
operator must use counts or phrases which do not conflict with normal 
operating signals, and must end with the station's call sign. Test 
signals must not exceed ten seconds, and must not be repeated until at 
least one minute has elapsed. On the frequency 2182 kHz or 156.800 MHz, 
the time between tests must be a minimum of five minutes.
    (b) Testing of transmitters must be confined to single frequency 
channels on working frequencies. However, 2182 kHz and 156.800 MHz may 
be used to contact ship or coast stations as appropriate when signal 
reports are necessary. Short tests on 4125 kHz are permitted by vessels 
equipped with MF/HF radios to evaluate the compatibility of the 
equipment for distress and safety purposes. U.S. Coast Guard stations 
may be contacted on 2182 kHz or 156.800

[[Page 38]]

MHz for test purposes only when tests are being conducted by Commission 
employees, when FCC-licensed technicians are conducting inspections on 
behalf of the Commission, when qualified technicians are installing or 
repairing radiotelephone equipment, or when qualified ship's personnel 
conduct an operational check requested by the U.S. Coast Guard. In these 
cases the test must be identified as ``FCC'' or ``technical.''
    (c) Survival craft transmitter tests must not be made within 
actuating range of automatic alarm receivers.

[51 FR 31213, Sept. 2, 1986, as amended at 63 FR 29659, June 1, 1998; 68 
FR 46961, Aug. 7, 2003]



Sec.  80.102  Radiotelephone station identification.

    This section applies to all stations using telephony which are 
subject to this part.
    (a) Except as provided in paragraphs (d) and (e) of this section, 
stations must give the call sign in English. Identification must be 
made:
    (1) At the beginning and end of each communication with any other 
station.
    (2) At 15 minute intervals when transmission is sustained for more 
than 15 minutes. When public correspondence is being exchanged with a 
ship or aircraft station, the identification may be deferred until the 
completion of the communications.
    (b) Private coast stations located at drawbridges and transmitting 
on the navigation frequency 156.650 MHz may identify by use of the name 
of the bridge in lieu of the call sign.
    (c) Ship stations transmitting on any authorized VHF bridge-to-
bridge channel may be identified by the name of the ship in lieu of the 
call sign.
    (d) Ship stations operating in a vessel traffic service system or on 
a waterway under the control of a U.S. Government agency or a foreign 
authoriy, when communicating with such an agency or authority may be 
identified by the name of the ship in lieu of the call sign, or as 
directed by the agency or foreign authority.
    (e) Voice traffic in the INMARSAT system is closed to other parties 
except the two stations involved and the identification is done 
automatically with the establishment of the call. Therefore, it is not 
necessary for these stations to identify themselves periodically during 
the communication. For terrestrial systems using DSC to establish 
radiotelephone communications, the identification is made at the 
beginning of the call. In these cases, both parties must identify 
themselves by ship name, call sign or MMSI at least once every 15 
minutes during radiotelephone communications.
    (f) VHF public coast stations licensed to serve a predetermined 
geographic service area are not required to provide station 
identification under this section. A site-based VHF public coast station 
may identify by means of the approximate geographic location of the 
station or the area it serves when it is the only VHF public coast 
station serving the location or there will be no conflict with the 
identification of any other station.

Sec.  80.103  Digital selective calling (DSC) operating procedures.

    (a) Operating procedures for the use of DSC equipment in the 
maritime mobile service are as contained in ITU-R M.541-9 (incorporated 
by reference, see Sec.  80.7), and subpart W of this part.
    (b) When using DSC techniques, coast stations and ship stations must 
use maritime mobile service identities (MMSI) assigned by the Commission 
or its designees.
    (c) DSC acknowledgment of DSC distress and safety calls must be made 
by designated coast stations and such acknowledgment must be in 
accordance with procedures contained in ITU-R M.541-9 (incorporated by 
reference, see Sec.  80.7). Nondesignated public and private coast 
stations must follow the guidance provided for ship stations in ITU-R 
M.541-9 (incorporated by reference, see Sec.  80.7), with respect to DSC 
``Acknowledgment of distress calls'' and ``Distress relays.'' (See 
subpart W of this part.)
    (d) Group calls to vessels under the common control of a single 
entity are authorized. A group call identity may be created from an MMSI 
ending in a zero, assigned to this single entity, by

[[Page 39]]

deleting the trailing zero and adding a leading zero to the identity.

Sec.  80.111  Radiotelephone operating procedures for coast stations.

    This section applies to all coast stations using telephony which are 
subject to this part.
    (a) Limitations on calling. (1) Except when transmitting a general 
call to all stations for announcing or preceding the transmission of 
distress, urgency, or safety messages, a coast station must call the 
particular station(s) with which it intends to communicate.
    (2) Coast stations must call ship stations by voice unless it is 
known that the particular ship station may be contacted by other means 
such as automatic actuation of a selective ringing or calling device.
    (3) Coast stations may be authorized emission for selective calling 
on each working frequency.
    (4) Calling a particular station must not continue for more than one 
minute in each instance. If the called station does not reply, that 
station must not again be called for two minutes. When a called station 
does not reply to a call sent three times at intervals of two minutes, 
the calling must cease for fifteen minutes. However, if harmful 
interference will not be caused to other communications in progress, the 
call may be repeated after three minutes.
    (5) A coast station must not attempt to communicate with a ship 
station that has specifically called another coast station until it 
becomes evident that the called station does not answer, or that 
communication between the ship station and the called station cannot be 
carried on because of unsatisfactory operating conditions.
    (6) Calls to establish communication must be initiated on an 
available common working frequency when such a frequency exists and it 
is known that the called ship maintains a simultaneous watch on the 
common working frequency and the appropriate calling frequency(ies).
    (b) Time limitation on calling frequency. Transmissions by coast 
stations on 2182 kHz or 156.800 MHz must be minimized and any one 
exchange of communications must not exceed one minute in duration.
    (c) Change to working frequency. After establishing communications 
with another station by call and reply on 2182 kHz or 156.800 MHz coast 
stations must change to an authorized working channel for the 
transmission of messages.
    (d) Use of busy signal. A coast station, when communicating with a 
ship station which transmits to the coast station on a radio channel 
which is a different channel from that used by the coast station for 
transmission, may transmit a ``busy'' signal whenever transmission from 
the ship station is being received. The characteristics of the ``busy'' 
signal are contained in Sec.  80.74.

the U.S. Government.



Sec.  80.115  Operational conditions for use of associated ship units.

    (a) Associated ship units may be operated under a ship station 
authorization. Use of an associated ship unit is restricted as follows;
    (1) It must only be operated on the safety and calling frequency 
156.800 MHz or 156.525 MHz or on commercial or noncommercial VHF 
intership frequencies appropriate to the class of ship station with 
which it is associated.
    (2) Except for safety purposes, it must only be used to communicate 
with the ship station with which it is associated or with associated 
ship units of the same ship station. Such associated ship units may be 
used from shore only adjacent to the waterway (such as on a dock or 
beach) where the ship is located. Communications from shore must relate 
to the operational

[[Page 41]]

and business needs of the ship including the transmission of safety 
information, and must be limited to the minimum practicable transmission 
time.
    (3) It must be equipped to transmit on the frequency 156.800 MHz or 
156.525 MHz and at least one appropriate intership frequency.
    (4) Calling must occur on the frequency 156.800 MHz or 156.525 MHz 
unless calling and working on an intership frequency has been 
prearranged.
    (5) Power is limited to one watt.
    (6) The station must be identified by the call sign of the ship 
station with which it is associated and an appropriate unit designator.
    (b) State or local government vehicles used to tow vessels involved 
in search and rescue operations are authorized to operate on maritime 
mobile frequencies as associated ship units. Such operations must be in 
accordance with paragraph (a) of this section, except that the

Sec.  80.116  Radiotelephone operating procedures for ship stations.

    (a) Calling coast stations. (1) Use by ship stations of the 
frequency 2182 kHz for calling coast stations and for replying to calls 
from coast stations is authorized. However, such calls and replies 
should be on the appropriate ship-shore working frequency.
    (2) Use by ship stations and marine utility stations of the 
frequency 156.800 MHz for calling coast stations and marine utility 
stations on shore, and for replying to calls from such stations, is 
authorized. However, such calls and replies should be made on the 
appropriate ship-shore working frequency.
    (b) Calling ship stations. (1) Except when other operating procedure 
is used to expedite safety communication, ship stations, before 
transmitting on the intership working frequencies 2003, 2142, 2638, 
2738, or 2830 kHz, must first establish communications with other ship 
stations by call and reply on 2182 kHz. Calls may be initiated on an 
intership working frequency when it is known that the called vessel 
maintains a simultaneous watch on the working frequency and on 2182 kHz.
    (2) Except when other operating procedures are used to expedite 
safety communications, the frequency 156.800 MHz must be used for call 
and reply by ship stations and marine utility stations before 
establishing communication on one of the intership working frequencies. 
Calls may be initiated on an intership working frequency when it is 
known that the called vessel maintains a simultaneous watch on the 
working frequency and on 156.800 MHz.
    (c) Change to working frequency. After establishing communication 
with another station by call and reply on 2182 kHz or 156.800 MHz 
stations on board ship must change to an authorized working frequency 
for the transmission of messages.
    (d) Limitations on calling. Calling a particular station must not 
continue for more than 30 seconds in each instance. If the called 
station does not reply, the station must not again be called until after 
an interval of 2 minutes. When a called station called does not reply to 
a call sent three times at intervals of 2 minutes, the calling must 
cease and must not be renewed until after an interval of 15 minutes; 
however, if there is no reason to believe that harmful interference will 
be caused to other communications in progress, the call sent three times 
at intervals of 2 minutes may be repeated after a pause of not less than 
3 minutes. In event of an emergency involving safety, the provisions of 
this paragraph do not apply.
    (e) Limitations on working. Any one exchange of communications 
between any two ship stations on 2003, 2142, 2638, 2738, or 2830 kHz or 
between a ship station and a private coast station on 2738 or 2830 kHz 
must not exceed 3 minutes after the stations have established contact. 
Subsequent to such exchange of communications, the same two stations 
must not again use 2003, 2142, 2638, 2738, or 2830 kHz for communication 
with each other until 10 minutes have elapsed.

[[Page 42]]

    (f) Transmission limitation on 2182 kHz and 156.800 MHz. To 
facilitate the reception of distress calls, all transmissions on 2182 
kHz and 156.800 MHz (channel 16) must be minimized and transmissions on 
156.800 MHz must not exceed 1 minute.
    (g) Limitations on commercial communication. On frequencies in the 
band 156-162 MHz, the exchange of commercial communication must be 
limited to the minimum practicable transmission time. In the conduct of 
ship-shore communication other than distress, stations on board ship 
must comply with instructions given by the private coast station or 
marine utility station on shore with which they are communicating.

Sec.  80.141  General provisions for ship stations.

    (a) Points of communication. Ship stations and marine utility 
stations on board ships are authorized to communicate with any station 
in the maritime mobile service.
    (b) Service requirements for all ship stations. (1) Each ship 
station must receive and acknowledge all communications which are 
addressed to the ship or to any person on board.
    (2) Every ship, on meeting with any direct danger to the navigation 
of other ships such as ice, a derelict vessel, a tropical storm, 
subfreezing air temperatures associated with gale force winds causing 
severe icing on superstructures, or winds of force 10 or above on the 
Beaufort scale for which no storm warning has been received, must 
transmit related information to ships in the vicinity and to the 
authorities on land unless such action has already been taken by another 
station. All such radio messages must be preceded by the safety signal.
    (3) A ship station may accept communications for retransmission to 
any other station in the maritime mobile service. Whenever such messages 
or communications have been received and acknowledged by a ship station 
for this purpose, that station must retransmit the message as soon as 
possible.
    (c) Service requirements for vessels. Each ship station provided for 
compliance with Part II of Title III of the Communications Act must 
provide a public correspondence service on voyages of more than 24 hours 
for any person who requests the service. Compulsory radiotelephone ships 
must provide this service for at least four hours daily. The hours must 
be prominently posted at the principal operating location of the 
station.
    (d) Operating conditions. Effective August 1, 1994, VHF hand-held, 
portable transmitters used while connected to an external power source 
or a ship antenna must be equipped with an automatic timing device that 
deactivates the transmitter and reverts the transmitter to the receive

licensed to operate in the band 1605-3500 kHz must be able to receive 
and transmit J3E emission on the frequency 2182 kHz. Ship stations are 
additionally authorized to receive and transmit H3E emission for 
communications with foreign coast stations and with vessels of foreign 
registry. If the station is used for other than safety communications, 
it must be capable also of receiving and transmitting the J3E emission 
on at least two other frequencies in that band. However, ship stations 
which operate exclusively on the Mississippi River and its connecting 
waterways, and on high frequency bands above 3500 kHz, need be equipped 
with 2182 kHz and one other frequency within the band 1605-3500 kHz.
    (b) Except as provided in paragraph (c) of this section, at least 
one VHF radiotelephone transmitter/receiver must be able to transmit and

    Each compulsory vessel, while underway, must maintain a watch for 
radiotelephone distress calls on 156.800 MHz whenever such station is 
not being used for exchanging communications. For GMDSS ships, 156.525 
MHz is the calling frequency for distress, safety, and general 
communications using digital selective calling and the watch on 156.800 
MHz is provided so that ships not fitted with DSC will be able to call 
GMDSS ships, thus providing a link between GMDSS and non-GMDSS compliant 
ships. The watch on 156.800 MHz is not required:
    (a) Where a ship station is operating only with handheld bridge-to-
bridge VHF radio equipment under Sec.  80.143(c) of this part; or
    (b) For vessels subject to the Bridge-to-Bridge Act and 
participating in a Vessel Traffic Service (VTS) system when the watch is 
maintained on both the bridge-to-bridge frequency and a separately 
assigned VTS frequency.

license, or the rules and regulations of the Federal Communications 
Commission must within 10 days from such receipt, send a written answer, 
in duplicate, to the office of the Commission originating the official 
notice. If an answer cannot be sent or an acknowledgment made within 
such 10-day period by reason of illness or other unavoidable 
circumstances, acknowledgment and answer must be made at the earliest 
practicable date with a satisfactory explanation of the delay. The 
answer to each notice must be complete in itself and must not be 
abbreviated by references to other communications or answers to other 
notices. The answer must contain a full explanation of the incident 
involved and must set forth the action taken to prevent a continuation 
or recurrence. If the notice relates to lack of attention to or improper 
operation of the station or to log or watch discrepancies, the answer 
must give the name and license number of the licensed operator on duty.
    (b) When an official notice of violation, impending violation, or 
discrepancy, pertaining to any provision of Part II of Title III of the 
Communications Act or the radio provisions of the Safety Convention, is 
served upon the master or person responsible for a vessel and any 
instructions appearing on such document issued by a representative of

    (a) Transmitters must meet the following modulation requirements:
    (1) When double sideband emission is used the peak modulation must 
be maintained between 75 and 100 percent;
    (2) When phase or frequency modulation is used in the 156-162 MHz 
band the peak modulation must be maintained between 75 and 100 percent. 
A frequency deviation of 5 kHz is defined as 100 
percent peak modulation; and
    (3) In single sideband operation the upper sideband must be 
transmitted. Single sideband transmitters must automatically limit the 
peak envelope power to their authorized operating power and meet the 
requirements in Sec.  80.207(c).
    (b) Radiotelephone transmitters using A3E, F3E and G3E emission must 
have a modulation limiter to prevent any modulation over 100 percent. 
This requirement does not apply to survival craft transmitters, to 
transmitters that do not require a license or to transmitters whose 
output power does not exceed 3 watts.
    (c) Coast station transmitters operated in the 72.0-73.0 MHz and 
75.4-76.0 MHz bands must be equipped with an audio low-pass filter. The 
filter must be installed between the modulation limiter and the 
modulated radio frequency stage. At frequencies between 3 kHz and 15 kHz 
it must have an attenuation greater than at 1 kHz by at least 
40log10 (f/3) dB where ``f'' is the frequency in kilohertz. 
At frequencies above 15 kHz the attenuation must be at least 28 dB 
greater than at 1 kHz.
    (d) Ship and coast station transmitters operating in the 156-162 MHz

greater than at 1 kHz by at least 60log10(f/3) dB where ``f'' 
is the audio frequency in kilohertz. At frequencies above 20 kHz the

159.480 MHz, 160.725 MHz, 160.785 MHz, 454.000 MHz and 459.000 MHz must 
employ a duty cycle with a maximum transmission period of 60 seconds 
followed by a minimum quiescent period four times the duration of the 
transmission period.
    (g) Radar stations operating in the bands above 2.4 GHz may use any 
type of modulation consistent with the bandwidth requirements in Sec.  
80.209(b).

9300-9500 MHz band must operate in a variable frequency mode and respond 
on their operating frequencies with a maximum error equivalent to 100 
meters. Additionally, their response must be encoded with a Morse 
character starting with a dash. The duration of a Morse dot is defined 
as equal to the width of a space and \1/3\ of the width of a Morse dash. 
The duration of the response code must not exceed 50 microseconds. The 
sensitivity of the stations must be adjustable so that received signals 
below -10 dBm at the antenna will not activate the transponder. Antenna 
polarization must be horizontal when operating in the 9300-9500 MHz band 
and either horizontal or both horizontal and vertical when operating in 
the 2900-3100 MHz band. Racons using frequency agile transmitting 
techniques must include circuitry designed to reduce interference caused 
by triggering from radar antenna sidelobes.
    (i) Variable frequency ship station transponders operating in the 
2900-3100 MHz or 9300-9500 MHz band that are not used for search and 
rescue purposes must meet the following requirements:
    (1) Non-selectable transponders must have the following 
characteristics:

[[Page 59]]

    (i) They must respond on all their frequencies with a maximum range 
error equivalent to 100 meters;
    (ii) They must use a Morse encoding of ``PS'' (dot-dash-dash-dot, 
dot-dot-dot), meaning ``You should not come any closer''. The width of a 
Morse dot is defined as equal to the width of a space and \1/3\ of the 
width of a Morse dash;
    (iii) When they employ swept frequency techniques they must not 
transmit on any frequency for more than 10 seconds in any 120 second 
period;
    (iv) Any range offset of their response must occur during their 
pause on the fixed frequency;
    (v) The duration of the response code must not exceed 50 
microseconds;

received signals below -10 dBm at the antenna input will not activate 
the transponder;
    (vii) Antenna polarization must be horizontal when operating in the 
9300-9500 MHz band and either horizontal or both horizontal and vertical 
when operating in the 2900-3100 MHz band.
    (viii) Transponders using frequency agile techniques must include 
circuitry designed to reduce interference caused by triggering from 
radar antenna sidelobes.
    (2) Selectable transponders must be authorized under part 5 of the

    (3) When located as described in paragraph (h)(2) of this section, 
the coast station (or stations affecting the same TV Grade B contour) 
will be authorized if the applicant's plan has limited the interference 
contour(s) to fewer than 100 residences or if the applicant:
    (i) Shows that the proposed site is the only suitable location 
(which, at the application stage, requires a showing that the proposed 
site is especially well-suited to provide the proposed service);

operation to TV reception within the Grade B contour that might develop 
within 90 days of the time it is notified in writing by the Commission. 
If this interference is not removed within the 90-day period, operation 
of the coast station must be discontinued. The licensee is expected to

earth station in any direction in the horizontal plane or in the 
direction of the space station must not exceed + 40 dB relative to one 
watt in any 4 kHz band in the main beam, except upon a satisfactory 
showing of need for greater power, in which case a maximum of + 55 dB 
relative to one watt may be authorized.
    (l) For operational fixed stations using frequencies in the 72-76 
MHz band and for other classes of stations operating above 162.025 MHz, 
the transmitter power must be specified in the station authorization. 
Frequencies in the 72-76 MHz band are listed in Sec.  80.381. The 
operational requirements for 72-76 MHz are contained in subpart L of 
this part.
    (m) For radiodetermination transmitters using A1D, A2D, F1D, F2D, 
G1D and G2D emissions on 154.585 MHz, 159.480 MHz, 160.725 MHz, 160.785

Sec.  80.291  Installation of direction finder.

    (a) The direction finder must be located to minimize interference 
from noise.
    (b) The direction finder antenna system must be erected so that the 
determination of bearings will not be hindered by the proximity of other 
antennas, cranes, wire halyards, or large metal objects.



Sec.  80.292  Contingent acceptance of direction finder calibration.

    When the required calibration can not be made before departure from 
a harbor or port for a voyage in the open sea, the direction finder may 
be tentatively approved on condition that the master certifies in 
writing that the direction finder will be calibrated by a competent 
technician.

Sec.  80.301  Watch requirements.

    (a) Each public coast station licensed to operate in the band 1605-
3500 kHz must monitor such frequency(s) as are used for working or, at 
the licensee's discretion, maintain a watch on 2182 kHz.
    (b) Except for distress, urgency or safety messages, coast stations 
must not transmit on 2182 kHz during the silence periods for three 
minutes twice each hour beginning at x h.00 and x h.30 Coordinated 
Universal Time (UTC).
    (c) Each public coast station must provide assistance for distress 
communications when requested by the Coast Guard.

[51 FR 31213, Sept. 2, 1986, as amended at 69 FR 64673, Nov. 8, 2004]



Sec.  80.302  Notice of discontinuance, reduction, or impairment of service 
involving a distress watch.

    (a) When changes occur in the operation of a public coast station 
which include discontinuance, relocation, reduction or suspension of a 
watch required to be maintained on 2182 kHz or 156.800 MHz, notification 
must be made by the licensee to the nearest district office of the U.S. 
Coast Guard as soon as practicable. The notification must include the 
estimated or known resumption time of the watch.

    (b) [Reserved]

[68 FR 46967, Aug. 7, 2003, as amended at 69 FR 64673, Nov. 8, 2004]



Sec.  80.303  Watch on 156.800 MHz (Channel 16).

    (a) During its hours of operation, each coast station operating in 
the 156-162 MHz band and serving rivers, bays and inland lakes except 
the Great Lakes, must maintain a safety watch on the frequency 156.800 
MHz except when transmitting on 156.800 MHz.
    (b) A coast station is exempt from compliance with the watch 
requirement when Federal, State, or Local Government stations maintain a 
watch on 156.800 MHz over 95% of the coast station's service area. Each 
licensee exempted by rule must notify the nearest district office of the 
U.S. Coast Guard at least thirty days prior to discontinuing the watch, 
or in the case of new stations, at least thirty days prior to commencing 
service. The Coast Guard may require any coast station to maintain the 
watch temporarily or permanently. The Coast Guard may also require any 
coast station to remain capable of either immediately resuming the watch 
or providing the Coast Guard direct dial-up access to the necessary 
156.800 MHz transceiver at no charge so that the Coast Guard can 
maintain the watch.
    (c) If the government station(s) providing the 156.800 MHz watch 
over the service area of an exempt station temporarily discontinues that 
watch, the exempt coast station upon receiving notice of this condition 
must maintain the watch on 156.800 HMz during the discontinuance. 
Automated maritime communications systems' compliance with this 
requirement is limited to the use of existing facilities.

[51 FR 31213, Sept. 2, 1986, as amended at 52 FR 35245, Sept. 18, 1987;

Sec.  80.304  Watch requirement during silence periods.

    Each ship station operating on telephony on frequencies in the band 
1605-3500 kHz must maintain a watch on the frequency 2182 kHz. This 
watch must be maintained at least twice each hour for 3 minutes 
commencing at x h.00 and x h.30 Coordinated Universal Time (UTC) using 
either a loudspeaker or headphone. Except for distress, urgency or 
safety messages, ship stations must not transmit during the silence 
periods on 2182 kHz.

[69 FR 64673, Nov. 8, 2004]



Sec.  80.305  Watch requirements of the Communications Act 
and the Safety Convention.

    (a) Each ship of the United States which is equipped with a 
radiotelegraph station for compliance with part II of title III of the 
Communications Act or chapter IV of the Safety Convention must:
    (1) If it is not carrying MF-DSC radio equipment, keep a continuous 
and efficient watch on the radiotelephone distress frequency 2182 kHz 
from the principal radio operating position or the room from which the 
vessel is normally steered while being navigated in the open sea outside 
a harbor or port.
    (2) Keep a continuous and efficient watch on the VHF distress 
frequency 156.800 MHz from the room from which the vessel is normally 
steered while in the open sea outside a harbor or port. The watch must 
be maintained by a designated member of the crew who may perform other 
duties, relating to the operation or navigation of the vessel, provided 
such other duties do not interfere with the effectiveness of the watch. 
Use of a properly adjusted squelch or brief interruptions due to other 
nearby VHF transmissions are not considered to adversely affect the 
continuity or efficiency of the required watch on the VHF distress 
frequency. This watch need not be maintained by vessels subject to the 
Bridge-to-Bridge Act and participating in a Vessel Traffic Services 
(VTS) system as required or recommended by the U.S. Coast Guard, when an 
efficient listening watch is maintained on both the bridge-to-bridge 
frequency and a separate assigned VTS frequency.
    (b) Each cargo ship of the United States which is equipped with a 
radiotelephone station for compliance with part II of title III of the 
Communications Act or chapter IV of the Safety Convention must while 
being navigated outside of a harbor or port:

[[Page 71]]

    (1) If it is not carrying MF-DSC radio equipment, keep a continuous 
watch on 2182 kHz in the room from which the vessel is normally steered 
while at sea, whenever such station is not being used for authorized 
traffic. Such watch must be maintained by at least one officer or 
crewmember who may perform other duties relating to the operation or 
navigation of the vessel, provided such other duties do not interfere 
with the watch.
    (2) Keep a continuous watch on 156.800 MHz from the room from which 
the vessel is normally steered. The watch must be maintained by a 
crewmember who may perform other duties, relating to the operation or 
navigation of the vessel, provided such other duties do not interfere 
with the watch. Use of properly adjusted squelch of brief interruptions 
due to other nearby VHF transmissions are not considered to adversely 
affect the watch. This watch need not be maintained by vessels subject 
to the Bridge-to-Bridge Act and participating in a Vessel Traffic 
Services (VTS) system when a watch is maintained on both the bridge-to-
bridge frequency and a VTS frequency.
    (c) Each vessel of the United States transporting more than six 
passengers for hire, which is equipped with a radiotelephone station for 
compliance with 47 U.S.C. 381-386 but which is not carrying MF-DSC radio 
equipment, must, while being navigated in the open sea or any tidewater 
within the jurisdiction of the United States adjacent or contiguous to 
the open sea, keep a continuous watch on 2182 kHz while the vessel is 
beyond VHF communication range of the nearest VHF coast station, 
whenever the radiotelephone station is not being used for authorized 
traffic. A VHF watch must be kept on 156.800 MHz whenever such station 
is not being used for authorized traffic. The VHF watch must be 
maintained at the vessel's steering station actually in use by the 
qualified operator as defined by Sec.  80.157 or by a crewmember who may 
perform other duties relating to the operation or navigation of the 
vessel, provided such other duties do not interfere with the watch. The 
use of a properly adjusted squelch is not considered to adversely affect 
the watch. The VHF watch need not be maintained by vessels subject to 
the Bridge-to-Bridge Act and participating in a Vessel Traffic Services 
(VTS) system when an efficient listening watch is maintained on both the 
bridge-to-bridge frequency and a VTS frequency.

2011]



Sec.  80.307  Compulsory use of radiotelegraph auto alarm.

    The radiotelegraph auto alarm required on a cargo ship subject to 
the radiotelegraph provisions of part II of title III of the 
Communications Act or the Safety Convention must be in operation, 
connected to the main antenna and adjusted for optimum efficiency at all 
times while the ship is being navigated in the open sea when a radio 
officer is not listening on the frequency 500 kHz, except under the 
circumstances as set forth in Sec.  80.306(b).



Sec.  80.308  Watch required by the Great Lakes Radio Agreement.

    (a) Each ship of the United States that is equipped with a 
radiotelephone station for compliance with the Great Lakes Radio 
Agreement must when underway keep a watch on:
    (1) 156.800 MHz on board a vessel 20 meters (65 feet) and over in 
length, a vessel engaged in towing (See Sec.  80.951(b)), or a vessel 
carrying more than 6 passengers for hire. This watch must be maintained 
whenever the station is not being used for authorized traffic. However, 
a watch on 156.800 MHz need not be maintained by a vessel maintaining a 
watch on the bridge-to-bridge frequency 156.650 MHz and participating in 
a Vessel Traffic Services (VTS) system and maintaining a watch on the 
specified VTS frequency.
    (2) 156.650 MHz on board a vessel 38 meters (124 feet) and over in 
length, a vessel engaged in towing (See Sec.  80.951(b)), or a vessel 
carrying more than six passengers for hire. This watch must be 
maintained continuously and effectively. Sequential monitoring is not 
sufficient. Portable VHF equipment may be used to meet this requirement. 
Vessels are exempted from this requirement while transiting the St. 
Lawrence Seaway and complying

[[Page 72]]

with the Joint Regulations of the St. Lawrence Seaway Authority and St. 
Lawrence Seaway Development Corporation between the lower exit of St. 
Lambert Lock at Montreal and Crossover Island, New York and in the 
Welland Canal and approaches between Calling in Point No. 15 and No. 16.
    (b) The watch must be maintained by the master, or person designated 
by the master, who may perform other duties provided they do not 
interfere with the effectiveness of the watch.

[53 FR 17052, May 13, 1988]



Sec.  80.309  Watch required by the Bridge-to-Bridge Act.

    In addition to the watch requirement contained in Sec.  80.148, all 
vessels subject to the Bridge-to-Bridge Act must keep a watch on the 
designated navigational frequency. The watch must be maintained by the 
master or person in charge of the vessel or the person designated by the 
master or person in charge to pilot or direct the movement of the 
vessel. The person standing watch may perform other duties provided such 
other duties do not interfere with the watch.

[51 FR 31213, Sept. 2, 1986, as amended at 57 FR 61012, Dec. 23, 1992]



Sec.  80.310  Watch required by voluntary vessels.

    Voluntary vessels not equipped with DSC must maintain a watch on 
2182 kHz and on 156.800 MHz (Channel 16) whenever the vessel is underway 
and the radio is not being used to communicate. Noncommercial vessels, 
such as recreational boats, may alternatively maintain a watch on 
156.450 MHz (Channel 9) in lieu of VHF Channel 16 for call and reply 
purposes. Voluntary vessels equipped with VHF-DSC equipment must 
maintain a watch on 2182 kHz and on either 156.525 MHz (Channel 70) or 
VHF Channel 16 aurally whenever the vessel is underway and the radio is 
not being used to communicate. Voluntary vessels equipped with MF-HF DSC 
equipment must have the radio turned on and set to an appropriate DSC 
distress calling channel or one of the radiotelephone distress channels 
whenever the vessel is underway and the radio is not being used to 
communicate. Voluntary vessels equipped with a GMDSS-approved Inmarsat 
system must have the unit turned on and set to receive calls whenever 
the vessel is underway and the radio is not being used to communicate.

[76 FR 67612, Nov. 2, 2011]

             Distress, Alarm, Urgency and Safety Procedures



Sec.  80.311  Authority for distress transmission.

    A mobile station in distress may use any means at its disposal to 
attract attention, make known its position, and obtain help. A distress 
call and message, however, must be transmitted only on the authority of 
the master or person responsible for the mobile station. No person shall 
knowingly transmit, or cause to be transmitted, any false or fraudulent 
signal of distress or related communication.



Sec.  80.312  Priority of distress transmissions.

    The distress call has absolute priority over all other 
transmissions. All stations which hear it must immediately cease any 
transmission capable of interfering with the distress traffic and must 
continue to listen on the frequency used for the emission of the 
distress call. This call must not be addressed to a particular station. 
Acknowledgement of receipt must not be given before the distress message 
which follows it is sent.



Sec.  80.313  Frequencies for use in distress.

    The frequencies specified in the bands below are for use by mobile 
stations in distress. The conventional emission is shown. When a ship 
station cannot transmit on the designated frequency or the conventional 
emission, it may use any available frequency or emission. Frequencies 
for distress and safety calling using digital selective calling 
techniques are listed in Sec.  80.359(b). Distress and safety NB-DP 
frequencies are indicated by footnote 2 in Sec.  80.361(b).

Aug. 7, 2003; 73 FR 4485, Jan. 25, 2008]



Sec.  80.314  Distress communications.

    (a) The international radiotelephone distress signal consists of the 
word MAYDAY, pronounced as the French expression ``m'aider''.
    (b) These distress signals indicate that a mobile station is 
threatened by grave and imminent danger and requests immediate 
assistance.
    (c) The radiotelephone distress call consists of:
    (1) The distress signal MAYDAY spoken three times;
    (2) The words THIS IS;
    (3) The call sign (or name, if no call sign assigned) of the mobile 
station in distress, spoken three times;
    (4) Particulars of the station's position;
    (5) The nature of the distress;
    (6) The kind of assistance desired; and
    (7) Any other information which might facilitate rescue, for 
example, the length, color, and type of vessel, or number of persons on 
board.
    (d) The procedures for canceling false distress alerts are contained 
in Sec.  80.335.

[51 FR 31213, Sept. 2, 1986, as amended at 68 FR 46968, Aug. 7, 2003; 73 
FR 4485, Jan. 25, 2008]



Sec.  80.317  Radiotelegraph and radiotelephone alarm signals.

    (a) The international radiotelegraph alarm signal consists of a 
series of twelve dashes sent in one minute, the duration of each dash 
being four seconds and the duration of the interval between consecutive 
dashes one second. The purpose of this special signal is the actuation 
of automatic devices giving the alarm to attract the attention of the 
operator when there is no listening watch on the distress frequency.
    (b) The international radiotelephone alarm signal consists of two 
substantially sinusoidal audio frequency tones transmitted alternately. 
One tone must have a frequency of 2200 Hertz and the other a frequency 
of 1300 Hertz, the duration of each tone being 250 milliseconds. When 
generated by automatic means, the radiotelephone alarm signal must be 
transmitted continuously for a period of at least 30 seconds, but not 
exceeding one minute; when generated by other means, the signal must be 
transmitted as continuously as practicable over a period of 
approximately one minute. The purpose of this special signal is to 
attract the attention of the person on watch or to actuate automatic 
devices giving the alarm.



Sec.  80.318  Use of alarm signals.

    (a) The radiotelegraph or radiotelephone alarm signal, as 
appropriate, must only be used to announce:
    (1) That a distress call or message is about to follow;
    (2) The transmission of an urgent cyclone warning. In this case the 
alarm signal may only be used by coast stations authorized by the 
Commission to do so; or
    (3) The loss of a person or persons overboard. In this case the 
alarm signal may only be used when the assistance of other ships is 
required and cannot be satisfactorily obtained by the use of the urgency 
signal only, but the alarm signal must not be repeated by other 
stations. The message must be preceded by the urgency signal.
    (b) In cases described in paragraphs (a)(2) and (3) of this section, 
the transmission of the warning or message by radiotelegraphy must not 
begin until two minutes after the end of the radiotelegraph alarm 
signal.



Sec.  80.319  Radiotelegraph distress call and message transmission procedure.

    (a) The radiotelegraph distress procedure consists of the following 
six steps: however, when time is vital, the first and second steps may 
be omitted. These two steps of the distress procedure may also be 
omitted in circumstances when transmission of the alarm signal is 
considered unnecessary:

[[Page 74]]

    (1) The radiotelegraph alarm signal;
    (2) The distress call and an interval of two minutes;
    (3) The distress call;
    (4) The distress message;
    (5) Two dashes of ten to fifteen seconds each;
    (6) The call sign of the mobile station in distress.
    (b) The radiotelegraph distress transmissions must be sent by means 
of the international Morse code at a speed not exceeding 16 words per 
minute nor less than 8 words per minute.
    (c) The distress message, preceded by the distress call, must be 
repeated at intervals until an answer is received. The radiotelegraph 
alarm signal may also be repeated, if necessary.
    (d) The transmissions under paragraphs (a) (5) and (6) of this 
section, which are to permit direction finding stations to determine the 
position of the station in distress, may be repeated at frequent 
intervals if necessary.
    (e) When the mobile station in distress receives no answer to a 
distress message transmitted on the distress frequency, the message may 
be repeated on any other available frequency on which attention might be 
attracted.

[51 FR 31213, Sept. 2, 1986, as amended at 69 FR 64674, Nov. 8, 2004]



Sec.  80.320  Radiotelephone distress call and message transmission procedure.

    (a) The radiotelephone distress procedure consists of:
    (1) The radiotelephone alarm signal (whenever possible);
    (2) The distress call;
    (3) The distress message.
    (b) The DSC distress procedure consists of:
    (1) Transmission by a mobile unit in distress;
    (2) Reception;
    (3) Acknowledgement of distress calls;
    (4) Distress relays.
    (c) Radiotelephone distress transmissions must be made slowly and 
distinctly, each word being clearly pronounced to facilitate 
transcription.
    (d) After the transmission by radiotelephony of its distress 
message, the mobile station may be requested to transmit suitable 
signals followed by its call sign or name, to permit direction-finding 
stations to determine its position. This request may be repeated at 
frequent intervals if necessary.
    (e) The distress message, preceded by the distress call, must be 
repeated at intervals until an answer is received. This repetition must 
be preceded by the radiotelephone alarm signal whenever possible.
    (f) When the mobile station in distress receives no answer to a 
distress message transmitted on the distress frequency, the message may 
be repeated on any other available frequency on which attention might be 
attracted.

[51 FR 31213, Sept. 2, 1986, as amended]



Sec.  80.321  Acknowledgement of receipt of distress message.

    (a) Stations of the maritime mobile service which receive a distress 
message from a mobile station which is beyond any possible doubt in 
their vicinity must immediately acknowledge receipt. However, in areas 
where reliable communication with one or more coast stations is 
practicable, ship stations may defer this acknowledgement for a short 
interval so that a coast station may acknowledge receipt.
    (b) Stations of the maritime mobile service which receive a distress 
message from a mobile station which beyond any possible doubt is not in 
their vicinity, must allow a short interval of time to elapse before 
acknowledging receipt of the message in order to permit stations nearer 
to the mobile station in distress to acknowledge receipt without 
interference.



Sec.  80.322  Form of acknowledgement.

    (a) The acknowledgement of receipt of a radiotelegraph distress 
message is transmitted in the following form:
    (1) The distress signal SOS;
    (2) The call sign of the station sending the distress message, sent 
three times;
    (3) The word DE;
    (4) The call sign of the station acknowledging receipt, sent three 
times;
    (5) The group RRR;
    (6) The message signal SOS.

[[Page 75]]

    (b) The acknowledgement of receipt of a radiotelephone distress 
message is transmitted in the following form:
    (1) The distress signal MAYDAY;
    (2) The call sign or other identification of the station sending the 
distress message, spoken three times;
    (3) The words THIS IS;
    (4) The call sign or other identification of the station 
acknowledging receipt, spoken three times;
    (5) The word RECEIVED;
    (6) The distress signal MAYDAY.



Sec.  80.323  Information furnished by an acknowledging station.

    (a) Every mobile station which acknowledges receipt of a distress 
message must on the order of the master or person responsible for the 
ship, aircraft, or other vehicle carrying such mobile station, transmit 
as soon as possible the following information in the order shown:
    (1) Its identifier;
    (2) Its position;
    (3) The speed at which it is proceeding towards, and the approximate 
time it will take to reach the mobile station in distress.
    (b) Before sending this message, the station must ensure that it 
will not interfere with the emissions of other stations better situated 
to render immediate assistance to the station in distress.



Sec.  80.324  Transmission of distress message by station 
not itself in distress.

    (a) A mobile station or a land station which learns that a mobile 
station is in distress must transmit a distress message in any of the 
following cases:
    (1) When the station in distress cannot transmit the distress 
message.
    (2) When the master or person responsible for the ship, aircraft, or 
other vehicle not in distress, or for the land station, believes that 
further help is necessary.
    (3) When, although not in a position to assist, it has heard a 
distress message which has not been acknowledged. When a mobile station 
transmits such a distress message, it must notify the authorities who 
may be able to assist.
    (b) Transmission must be made on the international distress 
frequencies or on any other available frequency on which attention might 
be attracted.
    (c) Transmission of the distress message must always be preceded by 
the call indicated below, which must itself be preceded whenever 
possible by the radiotelegraph or radiotelephone alarm signal. This call 
consists of:
    (1) When radiotelegraphy is used:
    (i) The signal DDD SOS SOS SOS DDD:
    (ii) The word DE;
    (iii) The call sign of the transmitting station, sent three times.
    (2) When radiotelephony is used:
    (i) The signal MAYDAY RELAY, spoken three times;
    (ii) The words THIS IS;
    (iii) The call sign or other identification of the transmitting 
station, spoken three times.
    (d) When the radiotelegraph alarm signal is used, an interval of two 
minutes must be allowed, whenever this is considered necessary, before 
the transmission of the call mentioned in paragraph (c)(1) of this 
section.



Sec.  80.325  Control of distress traffic.

    (a) Distress traffic consists of all messages relating to the 
immediate assistance required by the mobile station in distress. In 
distress traffic, the distress signal must be sent before the call and 
at the beginning of the preamble of any radiotelegram.
    (b) The control of distress traffic is the responsibility of the 
mobile station in distress or of the station which has sent the distress 
message. These stations may delegate the control of the distress traffic 
to another station.
    (c) The station in distress or the station in control of distress 
traffic may impose silence either on all stations of the mobile service 
in the area or on any station which interferes with the distress 
traffic. It must address these instructions ``to all stations'' or to 
one station only, according to circumstances. In either case, it must 
use one of the following signals which are reserved for use by the 
mobile station in distress and for the station controlling distress 
traffic:
    (1) In radiotelegraphy, the abbreviation QRT, followed by the 
distress signal SOS.

[[Page 76]]

    (2) In radiotelephony, the signal SEELONCE MAYDAY.
    (d) If essential, any station of the mobile service near the ship, 
aircraft, or other vehicle in distress may also impose silence. It must 
use for this purpose:
    (1) In radiotelegraphy, the abbreviation QRT, followed by the word 
DISTRESS and its own call sign;
    (2) In radiotelephony, the word SEELONCE, followed by the word 
DISTRESS and its own call sign or other identification.



Sec.  80.326  Notification of resumption of normal working.

    (a) When distress traffic has ceased, or when complete silence is no 
longer necessary on a frequency which has been used for distress 
traffic, the station which has controlled this traffic must transmit on 
that frequency a message addressed ``to all stations'' indicating that 
normal working may be resumed.
    (1) In radiotelegraphy, this message consists of:
    (i) The distress signal SOS;
    (ii) The call ``to all stations'' (CQ), sent three times;
    (iii) The word DE;
    (iv) The call sign of the station sending the message;
    (v) The time of handing in the message;
    (vi) The name and call sign of the mobile station which was in 
distress;
    (vii) The service abbreviation QUM.
    (2) In radiotelephony, this message consists of:
    (i) The distress signal MAYDAY;
    (ii) The call ``Hello all stations'', spoken three times;
    (iii) The words THIS IS;
    (iv) The call sign or other identification of the station sending 
the message;
    (v) The time of handing in of the message;
    (vi) The name and call sign of the mobile station which was in 
distress;
    (vii) The words SEELONCE FEENEE OR PRU-DONCE.
    (b) Until they receive the foregoing message indicating that normal 
or limited working may be resumed, all stations which are aware of the 
distress traffic, and which are not taking part in it, are forbidden to 
transmit on the frequencies on which the distress traffic is taking 
place.



Sec.  80.327  Urgency signals and messages.

    (a) The urgency signal indicates that the calling station has a very 
urgent message to transmit concerning the safety of a ship, aircraft, or 
other vehicle, or the safety of a person. The urgency signal must be 
sent only on the authority of the master or person responsible for the 
mobile station.
    (b) In radiotelegraphy, the urgency signal consists of three 
repetitions of the group XXX, sent with the individual letters of each 
group, and the successive groups clearly separated from each other. It 
must be transmitted before the call.
    (c) In radiotelephony, the urgency signal consists of three oral 
repetitions of the group of words PAN PAN transmitted before the call.
    (d) The urgency signal has priority over all other communications 
except distress. All mobile and land stations which hear it must not 
interfere with the transmission of the message which follows the urgency 
signal.
    (e) The urgency signal and call, and the message following it, must 
be sent on one of the international distress frequencies. Stations which 
cannot transmit on a distress frequency may use any other available 
frequency on which attention might be attracted.
    (f) Mobile stations which hear the urgency signal must continue to 
listen for at least three minutes. At the end of this period, if no 
urgency message has been heard, they may resume their normal service. 
However, land and mobile stations which are in communication on 
frequencies other than those used for the transmission of the urgency 
signal and of the call which follows it may continue their normal work 
without interruption provided the urgency message is not addressed ``to 
all stations''.
    (g) When the urgency signal has been sent before transmitting a 
message ``to all stations'' which calls for action by the stations 
receiving the message, the station responsible for its transmission must 
cancel it as soon as it knows that action is no longer necessary. This

[[Page 77]]

message of cancellation must likewise be addressed ``to all stations''.

73 FR 4485, Jan. 25, 2008]



Sec.  80.329  Safety signals and messages.

    (a) The safety signal indicates that the station is about to 
transmit a message concerning the safety of navigation or giving 
important meteorological warnings.
    (b) In radiotelegraphy, the safety signal consists of three 
repetitions of the group TTT, sent with the individual letters of each 
group, and the successive groups clearly separated from each other. It 
must be sent before the call.
    (c) In radiotelephony, the safety signal consists of the word 
SECURITE, pronounced as in French, spoken three times and transmitted 
before the call.
    (d) The safety signal and call must be sent on one of the 
international distress frequencies (2182 kHz or 156.8 MHz 
radiotelephone). Stations which cannot transmit on a distress frequency 
may use any other available frequency on which attention might be 
attracted.
    (e) The safety signal and call must be followed by the safety 
message. Where practicable, the safety message should be sent on a 
working frequency, and a suitable announcement to this effect must be 
made at the end of the call.
    (f) Messages about meteorological warnings, of cyclones, dangerous 
ice, dangerous wrecks, or any other imminent danger to marine navigation 
must be preceded by the safety signal.
    (g) Stations hearing the safety signal must not make any 
transmission likely to interfere with the message.

Sec.  80.331  Bridge-to-bridge communication procedure.

    (a) Vessels subject to the Bridge-to-Bridge Act transmitting on the 
designated navigational frequency must conduct communications in a 
format similar to those given below:
    (1) This is the (name of vessel). My position is (give readily 
identifiable position, course and speed) about to (describe contemplated 
action). Out.
    (2) Vessel off (give a readily identifiable position). This is (name 
of vessel) off (give a readily identifiable position). I plan to (give 
proposed course of action). Over.
    (3) (Coast station), this is (vessel's name) off (give readily 
identifiable position). I plan to (give proposed course of action). 
Over.
    (b) Vessels acknowledging receipt must answer ``(Name of vessel 
calling). This is (Name of vessel answering). Received your call,'' and 
follow with an indication of their intentions. Communications must 
terminate when each ship is satisfied that the other no longer poses a 
threat to its safety and is ended with ``Out''.
    (c) Use of power greater than 1 watt in a bridge-to-bridge station 
shall be limited to the following three situations:
    (1) Emergency.
    (2) Failure of the vessel being called to respond to a second call 
at low power.
    (3) A broadcast call as in paragraph (a)(1) of this section in a 
blind situation, e.g., rounding a bend in a river.



Sec.  80.332  Equipment to aid search and rescue operations.

    (a) Survival craft stations may transmit distress, urgency and 
safety signals, calls and messages.
    (b) EPIRB's may transmit only in accordance with the requirements of 
subparts V and X of this part.



Sec.  80.333  Stations in the maritime mobile-satellite service.

    The provisions of Sec. Sec.  80.311 and 80.324 apply to the 
operations of ship earth stations in the maritime mobile-satellite 
service.



Sec.  80.334  False distress alerts.

    A distress alert is false if it was transmitted without any 
indication that a mobile unit or person was in distress and required 
immediate assistance. Transmitting a false distress alert is prohibited 
and may be subject to the provisions of part 1, subpart A of this 
chapter if that alert:
    (a) Was transmitted intentionally;
    (b) Was not cancelled in accordance with Sec.  80.335;

[[Page 78]]

    (c) Could not be verified as a result of either the ship's failure 
to keep watch on appropriate frequencies in accordance with Sec.  
80.1123 or subpart G of this part, or its failure to respond to calls 
from the U.S. Coast Guard;
    (d) Was repeated; or
    (e) Was transmitted using a false identity.

[68 FR 46968, Aug. 7, 2003]



Sec.  80.335  Procedures for canceling false distress alerts.

    If a distress alert is inadvertently transmitted, the following 
steps shall be taken to cancel the distress alert.
    (a) VHF Digital Selective Calling.
    (1) Reset the equipment immediately;
    (2) Immediately cancel the distress alert orally over the telephony 
distress traffic channel associated with each DSC channel on which the 
distress alert was transmitted;
    (3) Set to Channel 16; and
    (4) Transmit a broadcast message to ``All stations'' giving the 
ship's name, call sign or registration number, and MMSI, and cancel the 
false distress alert.
    (b) MF Digital Selective Calling.
    (1) Reset the equipment immediately;
    (2) Immediately cancel the distress alert orally over the telephony 
distress traffic channel associated with each DSC channel on which the 
distress alert was transmitted; and
    (3) Tune for radiotelephony transmission on 2182 kHz; and
    (4) Transmit a broadcast message to ``All stations'' giving the 
ship's name, call sign or registration number, and MMSI, and cancel the 
false distress alert.
    (c) HF Digital Selective Calling;
    (1) Reset the equipment immediately;
    (2) Immediately cancel the distress alert orally over the telephony 
distress traffic channel associated with each DSC channel on which the 
distress alert was transmitted;
    (3) Tune for radiotelephony on the distress and safety frequency in 
each band in which a false distress alert was transmitted; and
    (4) Transmit a broadcast message to ``All stations'' giving the 
ship's name, call sign or registration number, and MMSI, and cancel the 
false distress alert frequency in each band in which a false distress 
alert was transmitted.
    (d) INMARSAT ship earth station. Immediately notify the appropriate 
rescue coordination center that the alert is cancelled by sending a 
distress priority message by way of the same land earth station through 
which the false distress alert was sent. Provide ship name, call sign or 
registration number, and INMARSAT identity with the cancelled alert 
message.
    (e) EPIRB. If for any reason an EPIRB is activated inadvertently, 
immediately contact the nearest U.S. Coast Guard unit or appropriate 
rescue coordination center by telephone, radio or ship earth station and 
cancel the distress alert.
    (f) General and other distress alerting systems. Notwithstanding 
paragraphs (a) through (e) of this section, ships may use additional 
appropriate means available to them to inform the nearest appropriate 
U.S. Coast Guard rescue coordination center that a false distress alert 
has been transmitted and should be cancelled.

Sec.  80.353  [Reserved]



Sec.  80.355  Distress, urgency, safety, call and reply Morse code frequencies.

    This section describes the distress, urgency, safety, call and reply 
carrier frequencies assignable to stations for Morse code 
radiotelegraphy.

[[Page 79]]

    (a) Frequencies in the 100-160 kHz band. The international calling 
frequency in the 100-160 kHz band is 143 kHz using A1A or J2A emission. 
When a ship station operating in the 100-160 kHz band desires to 
communicate with a coast station, it must call on the frequency 143 kHz 
unless the International List of Coast Stations provides otherwise. 
Coast stations must reply on their normal working frequency in this 
band. Only individual calls, replies to such calls, and transmission of 
signals preparatory to traffic may be transmitted on 143 kHz.
    (b) Frequencies in the 2000-27500 kHz band--(1) Ship station 
frequencies. The following table describes the calling frequencies in 
the 4000-27500 kHz band which are available for use by authorized ship 
stations equipped with crystal-controlled oscillators for A1A, J2A, J2B, 
or J2D radiotelegraphy. There are two series of frequencies for 
worldwide use and two series of frequencies for each geographic region. 
Ship stations with synthesized transmitters may operate on every full 
100 Hz increment in the 0.5 kHz channel for the frequencies listed, 
except for 100 Hz above and below those designated for worldwide use. 
During normal business hours when not communicating on other 
frequencies, all U.S. coast radiotelegraph stations must monitor the 
worldwide frequencies and the initial calling frequencies for the region 
in which it is located. The specific frequencies which must be monitored 
by a coast station will vary with propagation conditions. The calling 
frequencies which are routinely monitored by specific coast stations can 
be determined by reference to the ITU publication entitled ``List of 
Coast Stations.'' Initial calls by ship stations must be made on the 
appropriate initial calling frequency first. Calls on the worldwide 
frequencies may be made only after calls on the appropriate initial 
calling frequency are unsuccessful.

\1\ All frequencies in this table are shown in kilohertz. The use of frequencies in the 472-479 kHz band is restricted to public coast stations that
  were licensed on or before July 14, 2017.

    (2) Conditions of use. The following conditions are applicable to 
these frequencies:
    (i) Frequencies in the 100-160 kHz band are assignable to coast 
stations for high seas communications only;
    (ii) Frequencies above 5 MHz may be assigned primarily to stations 
serving the high seas and secondarily to stations serving inland waters 
of the United States, including the Great Lakes, under the condition 
that interference will not be caused to any coast station serving the 
high seas.
    (iii) The frequency 410 kHz may be used on a secondary basis for the 
transmission of radiodetermination information and for transmitting by 
radiotelegraph radiodetermination messages to direction-finding 
stations; and

Sec.  80.359  Frequencies for digital selective calling (DSC).

    (a) General purpose calling. The following table describes the 
calling frequencies for use by authorized ship and coast stations for 
general purpose DSC. There are three series of paried frequencies. One 
series is for worldwide use; the other two series are for regional use. 
The ``Series A'' designation includes coast stations along, and ship 
stations in, the Atlantic Ocean, the Gulf of Mexico, and the Caribbean 
Sea. The ``Series B'' designation includes stations in any remaining 
areas. Stations must initiate contact on the appropriate regional 
frequency depending upon the location of the called station and 
propagation conditions. Acknowledgement is made on the paired frequency. 
The worldwide frequencies may be used for international calling, if 
calls on the appropriate regional frequencies are unsuccessful, or the 
regional series does not contain the appropriate band (e.g., 2 MHz). 
During normal working hours, all public coast stations capable of DSC 
operations must monitor the worldwide and regional frequencies 
appropriate for its location. The specific frequencies to be monitored 
will vary with propagation conditions.

                             Radiotelephony



Sec.  80.365  Scope.

    The following sections describe the carrier frequencies and general 
conditions of use for the following types of radiotelephony:

    --Distress, urgency, safety, call and reply.
    --Working.
    --Public.
    --Private.



Sec.  80.367  General uses--radiotelephony.

    (a) Ship stations communicating with foreign coast stations may 
operate on any frequency designated by that coast station.
    (b) Radiotelephony stations communicating with a Government station 
may transmit on a Government frequency when authorized to do so by the 
Government station or agency if the emission, bandwidth and frequency 
tolerance of the maritime station are

[[Page 91]]

within the same limits as the Government station.
    (c) Frequencies assigned to Government radio stations are assignable 
to non-Government maritime stations for radiotelephony communications 
with other non-Government stations in connection with activities 
performed in coordination with or on behalf of the Government.
    (d) Frequencies in the 2000-27500 kHz band will be authorized only 
to ship stations that in addition are authorized to use frequencies in 
the 156-162 MHz band.
    (e) Frequencies in the 2000-2850 kHz band will be authorized to 
private coast stations that in addition are authorized to use 
frequencies in the 156-162 MHz band.
    (f) Ship and coast stations authorized to use frequencies in both 
the 2000-27500 kHz and 156-162 MHz bands must not use frequencies in the 
2000-27500 kHz band for communications with any other station which is 
within the VHF service range.
    (g) Coast and ship station radiotelephone working frequencies are 
available for DSC general purpose calling under the provisions of Sec.  
80.207(a).
    (h) Digital selective calling techniques are not authorized on the 
frequencies 2182 kHz or 156.800 MHz.



Sec.  80.369  Distress, urgency, safety, call and reply frequencies.

    This section describes the general uses and frequencies assignable 
to maritime stations for distress, urgency, safety, call and reply 
radiotelephony communications.
    (a) In the 1605-3500 kHz band, the frequency 2182 is an 
international radiotelephony distress, urgency and safety frequency for 
ship stations, public and private coast stations, and survival craft 
stations. It is also used for call and reply by ship stations on a 
primary basis and by public coast stations on a secondary basis. The 
carrier frequency 2191 kHz may be used as a supplementary calling 
frequency in areas of heavy usage of 2182 kHz. All stations must use J3E 
emission when operating on 2182 and 2191 kHz, except that:
    (1) H3E emission may be used on 2182 kHz for communications with 
foreign coast and ship stations; or,
    (2) A3E emission may be used on 2182 kHz by portable survival craft 
stations, or transmitters authorized for use prior to January 1, 1972. 
See Sec.  80.203(c).
    (b) The frequencies 4125.0 kHz, 6215 kHz, 8291 kHz, 12290 kHz, and 
16420 kHz may be used by coast and ship stations on a simplex basis for 
distress and safety communications. The frequency 4125.0 kHz may also be 
used for distress and safety communications between aircraft and 
maritime mobile stations.
    (c) The frequency 5167.5 kHz is available to any station for 
emergency communications in the State of Alaska. Peak envelope power of 
stations operating on this frequency must not exceed 150 watts. This 
frequency may also be used by Alaska private fixed stations for calling 
and listening, but only for establishing communication.
    (d) In the 4000-27500 kHz band, the following coast frequencies are 
available for assignment to public coast stations for call and reply 
communications. The paired ship frequencies are available for use by 
authorized ship stations.

indicated:
    (1) The frequencies 121.500 MHz and 123.100 MHz using A3E emission 
are available for scene of action search and rescue operations to ship, 
coast and aircraft stations. Communications in support of search and 
rescue operations must employ the frequency 121.500 MHz only when 
communications on 123.100

[[Page 92]]

MHz or other VHF frequencies is not practicable. Ship, coast and 
aircraft stations engaged in such communications on 121.500 MHz must 
shift to 123.100 MHz as soon as possible.
    (2) The frequency 156.525 MHz is available for intership, ship and 
coast general purpose, distress and safety DSC calls.
    (3) The frequency 156.800 MHz is the international radiotelephone 
distress, urgency, safety, call and reply frequency for ship, public and 
private coast stations. Stations operating on 156.800 MHz must be able 
to transmit and receive using G3E emission.
    (4) The frequency 156.450 MHz (channel 9) is available for 
intership, ship and coast station general purpose calling by 
noncommercial vessels, such as recreational boats. Distress, urgency and 
safety calls should initially be made on 156.800 MHz (channel 16) or, if 
equipped with DSC, on 156.525 MHz (channel 70).

\1\ Unlimited hours of use from December 15 to April 1 and day only from
  April 1 to December 15. Harmful interference must not be caused to any
  station in the Great Lakes region.
\2\ In the Great Lakes region 2206 kHz is not available for transmission
  to U.S. ships except in the case of distress. U.S. coast stations in
  the Great Lakes area may use 2514, 2550 and 2582 kHz on a shared basis
  with coast stations of Canada. Except in the case of distress, the
  frequency 2550 kHz must not be used for transmission to ship stations
  of Canada since the associated ship station transmit frequency 2158
  kHz is not available to Canadian ship stations for transmission and
  2582 kHz must not be used for public correspondence transmissions to
  U.S. ship stations since the associated ship transmit frequency 2206
  kHz is not available to U.S. ship stations for transmissions except in
  the case of distress.
\3\ Limited to a peak envelope power of 150 watts.
\4\ Harmful interference must not be caused to any coast station in the
  Caribbean region.
\5\ But see section 80.373(c)(3) of this chapter.

    (b) Working frequencies in the 4000-27500 kHz band. This paragraph 
describes the working carrier frequencies in the 4000-27500 kHz band. 
With respect to frequencies that are assignable in more than one 
geographical area, once the frequency is assigned to one licensee, any 
subsequent license will be authorized on a secondary, non-interference 
basis with respect to the incumbent license's existing operation. If the 
first licensee later seeks authorization to operate in an additional 
geographic area, such authorization will be on a secondary, non-
interference basis to other co-channel licensees.
    (1) The following table specifies the carrier frequencies available 
for assignment to public coast stations. The paired ship frequencies are 
available for use by authorized ship stations. The

[[Page 93]]

specific frequency assignment available to public coast stations for a 
particular geographic area is indicated by an ``x'' under the 
appropriate column. The allotment areas are in accordance with the 
``Standard Defined Areas'' as identified in the International Radio 
Regulations, Appendix 25 Planning System, and indicated in the preface 
to the International Frequency List (IFL).

    (2) The following table specifies the non-paired carrier frequencies 
that are available for assignment to public coast stations for simplex 
operations. These frequencies are available for use by authorized ship 
stations for transmissions to coast stations (simplex operations). 
Assignments on these frequencies must accept interference. They are 
shared with government users and are considered ``common use''

    (a) Special requirements for private coast stations. Assignment to 
private coast stations of radiotelephony frequencies in the 2000-27500 
kHz band are subject to the following:
    (1) Private coast stations must use J3E emission.
    (2) On 2182 kHz, private coast stations must be capable of receiving 
J3E and H3E emissions.
    (3) Except in the Mississippi River System and Great Lakes, private 
coast stations serving lakes or rivers are not authorized on the 2000-
2850 kHz band.
    (4) Private coast stations may use DSC for calling on their assigned 
frequencies in the 2000-27500 kHz band and on those frequencies in the 
156-162 MHz band which are allocated for maritime control, commercial 
and non-commercial communications.
    (b) Frequencies in the 2000-27500 kHz band for intership safety and 
other communications. This paragraph describes the geographic areas of 
operation and the frequencies and limitations in the band available for 
assignment for intership safety and operational simplex radiotelephone 
communications.
    (1) Frequencies avaiable.

\2\ Available on a secondary basis for intership communications by ships
  involved in non-commercial fishing.

    (2) Except for 2093.0 kHz and 2214.0 kHz the frequencies shown in 
paragraph (b)(1) of this section are authorized primarily for intership 
safety communications in the indicated geographic area.
    (3) Except for the frequencies 2093.0 kHz, 2214.0 kHz and 2670.0 
kHz, the frequencies shown in paragraph (b)(1) of this section may be 
used on a non-interference basis to safety communications, for 
operational communications and, in the case of commercial transport 
ships and ships of municipal and state governments, for business 
communications.
    (4) Ship stations may communicate with government coast stations on 
2003.0 kHz about passage of vessels. Interference must not be caused to 
communications on the St. Lawrence Seaway and on the St. Mary's River.
    (5) Ship stations may use 2670.0 kHz for communications with coast 
and ship stations of the U.S. Coast Guard. When a ship is not equipped 
to transmit on 2670.0 kHz or in the band 156-162 MHz the frequency 
2003.0 kHz may be used on the Great Lakes for communications must not 
cause harmful interference to intership safety, operational and business 
communications.

stations may be exchanged on 2738.0 kHz and 2830.0 kHz. The frequencies 
2214.0 kHz, 2738.0 kHz and 2830.0 kHz are assignable to private coast 
stations upon a showing that they need to communicate with commercial 
transport or Government ships. Private coast station applicants must 
show that public coast stations do not provide the required 
communications and harmful interference will not be caused to the 
intership use of these frequencies. The transmitter power must not 
exceed 150 watts. If 2214.0 kHz is authorized for ships, intership 
communication is also authorized. The geographic limitations to the 
frequencies 2738.0 kHz and 2830.0 kHz do not prohibit intership 
communication of less than 320 km (200 statute miles) when only one of 
the ship stations is within a permitted use geographic area.
    (7) Private aircraft stations may communicate with ship stations on 
2738.0 kHz and 2830.0 kHz if:
    (i) The communications are limited to business or operational needs

    (4) Channels in the 219-220 MHz band are also used on a secondary, 
non-interference basis by amateur stations participating in digital 
message forwarding systems. Amateur stations may not cause harmful 
interference to AMTS operations and must accept any harmful interference 
from AMTS operation. Amateur stations within 80 km (50 miles) of an AMTS 
coast station must obtain written approval from the AMTS licensee prior 
to operating in the 219-220 MHz band. Amateur stations within 640 km 
(398 miles) of an AMTS coast station must notify the AMTS licensee in 
writing at least 30 days prior to initiation of operations in the 219-
220 MHz band. All amateur stations must notify the American Radio Relay 
League in writing at least 30 days prior to initiation of operations in

[[Page 107]]

the 219-220 MHz band (ARRL, 225 Main St., Newington, CT 06111-1494).
    (b) Subject to the requirements of Sec.  1.924 of this chapter, 
Sec. Sec.  80.215(h), and 80.475(a), each AMTS geographic area licensee 
may place stations anywhere within its region without obtaining prior 
Commission approval provided:
    (1) The AMTS geographic area licensee must locate its stations at 
least 120 kilometers from the stations of co-channel site-based AMTS 
licensees. Shorter separations between such stations will be considered 
by the Commission on a case-by-case basis upon submission of a technical 
analysis indicating that at least 18 dB protection will be provided to a 
site-based licensee's predicted 38 dBu signal level contour. The site-
based licensee's predicted 38 dBu signal level contour shall be 
calculated using the F(50, 50) field strength chart for Channels 7-13 in 
Sec.  73.699 (Fig. 10) of this chapter, with a 9 dB correction for 
antenna height differential. The 18 dB protection to the site-based 
licensee's predicted 38 dBu signal level contour shall be calculated 
using the F(50, 10) field strength chart for Channels 7-13 in Sec.  
73.699 (Fig. 10a) of this chapter, with a 9 dB correction factor for 
antenna height differential.
    (2) The locations and/or technical parameters of the transmitters 
are such that individual coordination of the channel assignment(s) with 
a foreign administration, under applicable international agreements and 
rules in this part, is not required.
    (3) For any construction or alteration that would exceed the 
requirements of Sec.  17.7 of this chapter, licensees must notify the 
appropriate Regional Office of the Federal Aviation Administration (FAA 
Form 7460-1) and file a request for antenna height clearance and 
obstruction marking and lighting specifications (FCC Form 854) with the 
FCC, Attn: Information Processing Branch, 1270 Fairfield Rd., 
Gettysburg, PA 17325-7245.
    (4) The transmitters must not have a significant environmental 
effect as defined by Sec. Sec.  1.1301 through 1.1319 of this chapter.
    (c) Any recovered frequency blocks will revert automatically to the 
holder of the geographic area license within which such frequencies are 
included. Any frequency blocks recovered where there is no geographic 
area licensee will be retained by the Commission for future licensing.

    (2) 1.8 microvolts across 50 ohms.
    (3) + 17 dBu (decibels referred to 1 microvolt per meter).
    (4) 7 microvolts per meter.



Sec.  80.755  Applicability.

    Applications for maritime frequencies in the 156-162 MHz band must 
include a map showing the proposed service area contour. The service 
area contour must be computed in accordance with the following 
procedures.



Sec.  80.757  Topographical data.

    (a) In the preparation of profile graphs and in determining the 
location and height above sea level of the antenna site, the elevations 
or contour intervals must be taken from U.S. Geological Survey 
topographic quadrangle maps, U.S. Army Corps of Engineers maps or 
Tennessee Valley Authority maps, whichever is the latest, for all areas 
for which maps are available. If such maps are not published for the 
area in question, the next best topographic information must be used. 
The maps used must include the principal area to be served. U.S. 
Geological Survey topographic quadrangle maps may be obtained from the 
Eastern Distribution Branch, U.S. Geological Survey, 1200 South Eads 
Street, Arlington, VA 22202, for maps of areas east of the Mississippi 
River, including Minnesota, Puerto Rico, and the Virgin Islands, and 
from the Western Distribution Branch, U.S. Geological Survey, Federal 
Center, Denver CO 80225, for maps of areas west of the Mississippi 
River, including Alaska, Hawaii, Louisiana, Guam and American Samoa. 
Sectional aeronautical charts are available from the Distribution 
Division, National Ocean Service, Riverdale, MD 20840.
    (b) In lieu of maps, the average terrain elevation may be computer 
generated, using elevations from a 30 second point or better topographic 
data file such as those available for the U.S. Geological Survey's 
National Geographic Information Center or the National Oceanic and 
Atmospheric Administration's National Geophysical Data Center. In case 
of dispute maps will be used to determine the correct value.



Sec.  80.759  Average terrain elevation.

    (a)(1) Draw radials from the antenna site for each 45 degrees of 
azimuth starting with true north. Any such radial which extends entirely 
over land from the antenna site to the point of + 17 dBu field strength 
need not be drawn.
    (2) If the distance from the antenna site to the point of + 17 dBu 
field strength between any of the 45 degrees radials would be less than 
the distances calculated along these radials, an additional radial 
between such adjacent radials must be plotted and calculations made in 
each case. Each additional radial must be that radial along which it 
appears by inspection that transmission loss would be greatest.

[[Page 124]]

    (b) Draw a circle of 16 km (10 statute mile) radius using the 
antenna site as the center. Divide each radial into 320 meter (0.2 
statute mile) increments inside the circumference to the 3.2 km (2 
statute mile) point.
    (c) Calculate the height above sea level of each 320 meter (0.2 
statute mile) division by interpolating the contour intervals of the 
map, and record the value.
    (d) Average the values by adding them and dividing by the number of 
readings along each radial.
    (e) Calculate the height above average terrain by averaging the 
values calculated for each radial.

the other of the indicated types of units is required.
    (a) Graph 1. To convert effective radiated power in watts to dBk or 
to dBW, find the power in watts on the horizontal axis. Move vertically 
along the line representing the power to the diagonal line. Move 
horizontally from the diagonal to the right side to read dBW and to the 
left to read dBk.
    (b) Graph 2. To convert microvolts across 50 ohms to received power 
in dBW, find the signal in microvolts on the horizontal axis. Move 
vertically to the diagonal line, then move right horizontally to read 
dBW.

[GRAPHIC] [TIFF OMITTED] TC02AP91.004



Sec.  80.763  Effective antenna height.

    The effective height of the antenna is the vertical distance between 
the center of the radiating system above the mean sea level and the 
average terrain elevation.

[[Page 128]]



Sec.  80.765  Effective radiated power.

    Effective radiated power is used in computing the service area 
contour. The effective radiated power is derived from the transmitter 
output power, loss in the transmission system including duplexers, 
cavities, circulators, switches and filters, and the gain relative to a 
half-wave dipole of the antenna system.



Sec.  80.767  Propagation curve.

    The propagation graph, Sec.  80.767 Graph 1, must be used in 
computing the service area contour. The graph provides data for field 
strengths in dBu for an effective radiated power of 1 kW, over sea 
water, fresh water or land (smooth earth); transmitting antena heights 
of 4,800, 3,200, 1,600, 800, 400, 200, and 100 feet; based on a 
receiving antenna height of 9 meters (30 feet), for the 156-162 MHz 
band. The use of this is described in this section.
    (a) Calculate the effective radiated power of the coast station, Ps 
in dB referred to 1 kW (dBk), as follows:
[GRAPHIC] [TIFF OMITTED] TC02AP91.005

where,

Pt = Transmitter output power in dB referred to 1 kW: Transmitter output 
          power in watts is converted to dBk by Pt = 10 [log10 (Power in 
          watts)]-30. Also see Sec.  80.761 Graph 1 for a conversion 
          graph.
G = Antenna gain in dB referred to a standard half-wave dipole, in the 
          direction of each plotted radial, and
L = Line losses between the transmitter and the antenna, in dB.

    Notes: 1. To determine field strengths where the distance is known, 
for effective radiated powers other than 1kW (0 dBk): Enter the graph 
from the ``statute miles'' scale at the known distance, read up to 
intersection with the curve for the antenna height, read left to the 
``dBu for 1 kW radiated'' scale and note the referenced field strength 
(Fe). The value of the actual field strength (F) in dBu will be F = Fe + 
Ps where Ps is the effective radiated power calculated above.
    2. To determine distance, where the actual field strength is 
specified, for effective radiated powers other than 0 dBk: The value of 
the field referenced strength will be Fe = F-Ps in dBu. Enter the graph, 
from the ``dBu for 1 kW radiated'' scale at the corrected value of Fe, 
read right to intersection with the antenna height, read down to 
``statute miles'' scale.

    (b) Determine the antenna height. For antenna heights between the 
heights for which this graph is drawn, use linear interpolation; assume 
linear height-gain for antennas higher than 4,800 feet.
    (c) For receiver antenna heights lower than 9 meters (30 feet), 
assume that the field strength is the same as at 9 meters (30 feet).
    (d) Assume that propagation over fresh water or over land is the 
same as that over sea water.

Sec.  80.769  Shadow loss.

    Where the transmission path is obstructed the received signal must 
be adjusted to include shadow loss. Attenuation due to shadowing must be 
taken from Sec.  80.769 Graph 1, as follows:
    (a) Inspect the map(s) to determine if a hill(s) obstructs an 
imaginary line of

[[Page 130]]

sight (dashed line on illustrative profiles of Sec.  80.769 Graph 1 from 
the average terrain elevation at the coast station antenna to the water 
level at the ship location. If average terrain elevation exceeds the 
actual ground elevation at the antenna site, the latter elevation must 
be used as the average terrain elevation.
    (b) If a hill appears to obstruct the radio path, plot the antenna 
site elevation, the obstruction elevation and the height of the ship 
station on rectangular coordinate paper using elevation above mean sea 
level as the vertical scale and distance in statute miles as the 
horizontal scale. Then draw a straight line between the antenna and the 
ship.
    (c) If a hill obstructs the imaginary line of sight, determine its 
height (H) above the imaginary line and its distance (D) from either the 
coast or ship station, whichever is nearer, as illustrated by examples 
``A'' and ``B'' on Graph 1.
    (d) Read the shadow loss from this Graph 1 and subtract that loss 
from the computed received signal.
    (e) Where more than one hill obstructs the transmission path, 
determine the height and position of a single equivalent hill, as 
illustrated by example ``C'' on this graph. Read the shadow loss from 
this graph for the equivalent hill.

Sec.  80.771  Method of computing coverage.

    Compute the + 17 dBu contour as follows:
    (a) Determine the effective antenna height above mean sea level 
according to the procedures in Sec. Sec.  80.757-80.761.
    (b) Determine the effective radiated power according to Sec.  
80,765. Determine

[[Page 132]]

for each radial the distance from the antenna site to the + 17 dBu point 
of field strength using procedures of Sec. Sec.  80.765 and 80.767.
    (c) Plot on a suitable map each point of + 17 dBu field strength for 
all radials and draw the contour by connecting the adjacent points by a 
smooth curve.



Sec.  80.773  Co-channel interference protection.

    (a) Where a VHF public coast station geographic area licensee shares 
a frequency with an incumbent VHF public coast station licensee, the 
ratio of desired to undesired signal strengths must be at least 12 dB 
within the service area of the station.
    (b) Where a VHF public coast station geographic area licensee shares 
a frequency with an incumbent private land mobile radio licensee, the 
VHF public coast station geographic area licensee must provide at least 
10 dB protection to the PLMR incumbent's predicted 38 dBu signal level 
contour. The PLMR incumbent's predicted 38 dBu signal level contour is 
calculated using the F(50, 50) field strength chart for Channels 7-13 in 
Sec.  73.699 (Fig. 10a) of this chapter, with a 9 dB correction factor 
for antenna height differential, and is based on the licensee's 
authorized effective radiated power and antenna height-above-average-
terrain.
    (c) VHF public coast station geographic area licensees are 
prohibited from exceeding a field strength of + 5 dBu (decibels 
referenced to 1 microvolt per meter) at their service area boundaries, 
unless all the affected VHF public coast station geographic area 
licensees agree to the higher field strength.

notified.

[76 FR 67617, Nov. 2, 2011]

       Operating Procedures for Distress and Safety Communications



Sec.  80.1109  Distress, urgency, and safety communications.

    (a) Distress traffic consists of all messages relating to the 
immediate assistance required by the ship in distress, including search 
and rescue communications and on-scene communications. Distress traffic 
must as far as possible be on the frequencies contained in Sec.  
80.1077.
    (b) Urgency and safety communications include: navigational and 
meteorological warnings and urgent information; ship-to-ship safety 
navigation communications; ship reporting communications; support 
communications for search and rescue operations; other urgency and 
safety messages and communications relating to the navigation, movements 
and needs of ships and weather observation messages destined for an 
official meteorological service.
    (c) Intership navigation safety communications are those VHF 
radiotelephone communications conducted between ships for the purpose of 
contributing to the safe movement of ships. The frequency 156.650 MHz is 
used for intership navigation safety communications (see Sec.  80.1077).



Sec.  80.1111  Distress alerting.

    (a) The transmission of a distress alert indicates that a mobile 
unit or person is in distress and requires immediate assistance. The 
distress alert is a digital selective call using a distress call format 
in bands used for terrestrial radio communication or a distress message 
format, which is relayed through space stations.
    (b) The distress alert must be sent through a satellite either with 
absolute priority in general communication channels or on exclusive 
distress and safety frequencies or, alternatively, on the distress and 
safety frequencies in the MF, HF, and VHF bands using digital selective 
calling.
    (c) The distress alert must be sent only on the authority of the 
person responsible for the ship, aircraft or other vehicle carrying the 
mobile station or the mobile earth station.

[[Page 166]]

    (d) All stations which receive a distress alert transmitted by 
digital selective calling must immediately cease any transmission 
capable of interfering with distress traffic and must continue watch on 
the digital selective call distress calling channel until the call has 
been acknowledged to determine if a coast station acknowledges the call 
using digital selective calling. Additionally, the station receiving the 
distress alert must set watch on the associated distress traffic 
frequency for five minutes to determine if distress traffic takes place. 
The ship can acknowledge the call using voice or narrowband direct 
printing as appropriate on this channel to the ship or to the rescue 
authority.

[57 FR 9065, Mar. 16, 1992, as amended at 68 FR 46980, Aug. 7, 2003]



Sec.  80.1113  Transmission of a distress alert.

    (a) The distress alert must identify the station in distress and its 
position. The distress alert may also contain information regarding the 
nature of the distress, the type of assistance required, the course and 
speed of the mobile unit, the time that this information was recorded 
and any other information which might facilitate rescue.
    (b) The format of distress calls and distress messages must be in 
accordance with ITU-R M.493-13 and ITU-R M.541-9 (both incorporated by 
reference, see Sec.  80.7), as specified in Sec.  80.1101.
    (c) Ship-to-shore distress alerts are used to alert Rescue 
Coordination Centers via coast stations or coast earth stations that a 
ship is in distress. These alerts are based on the use of transmissions 
via satellites (from a ship earth station or a satellite EPIRB) and 
terrestrial services (from ship stations and EPIRBs).
    (d) Ship-to-ship distress alerts are used to alert other ships in 
the vicinity of the ship in distress and are based on the use of digital 
selective calling in the VHF and MF bands. The HF bands should not be 
used to notify ships in the vicinity unless no response is received 
within five minutes on VHF or MF.
    (e) Shore-to-ship distress alert relays are used by a station or 
Rescue Coordination Center to relay information about a ship in distress 
to, as appropriate, all ships, a selected group of ships, or a specific 
ship by satellite and/or terrestrial means. The distress alert relay 
must contain the identification of the mobile unit in distress, its 
position and all other information which might facilitate rescue.

[57 FR 9065, Mar. 16, 1992, as amended at 68 FR 46980, Aug. 7, 2003; 73 
FR 4491, Jan. 25, 2008; 76 FR 67617, Nov. 2, 2011]



Sec.  80.1114  False distress alerts.

    The provisions of Sec. Sec.  80.334 and 80.335 apply to false 
distress alerts.

[68 FR 46980, Aug. 7, 2003]



Sec.  80.1115  Transmission of a distress alert by a station 
not itself in distress.

    (a) A station in the mobile or mobile-satellite service which learns 
that a mobile unit is in distress must initiate and transmit a distress 
alert relay in any of the following cases:
    (1) When the mobile unit in distress is not itself in a position to 
transmit the distress alert; or
    (2) When the master or person responsible for the mobile unit not in 
distress or the person responsible for the land station determines that 
further help is necessary.
    (b) A station transmitting a distress alert relay in accordance with 
paragraph (a) of this section or Sec.  80.1121(c) must indicate that it 
is not itself in distress.



Sec.  80.1117  Procedure for receipt and acknowledgement of distress alerts.

    (a) Normally, distress calls received using digital selective 
calling are only acknowledged using a DSC acknowledgement by a coast 
station. Ships should delay any acknowledgement in order to give 
sufficient time for a coast station to acknowledge the call. In cases 
where no acknowledgement has been heard and no distress traffic has been 
heard, the ship should transmit a distress alert relay to the coast 
station. Upon advice from the Rescue Coordination Center, the ship may 
transmit a DSC acknowledgement call to stop it from being repeated. 
Acknowledgement by digital selective calling of

[[Page 167]]

receipt of a distress alert in the terrestrial services must comply with 
ITU-R M.541-9 (incorporated by reference, see Sec.  80.7).
    (b) Acknowledgement through a satellite of receipt of a distress 
alert from a ship earth station must be sent immediately (see Sec.  
80.1119).
    (c) Acknowledgement by radiotelephony of receipt of a distress alert 
from a ship station or a ship earth station must be given in the 
following form:
    (1) The distress signal MAYDAY;
    (2) The call sign or other identification of the station sending the 
distress message, spoken three times;
    (3) The words THIS IS (or DE spoken as DELTA ECHO in case of 
language difficulties);
    (4) The call sign or other identification of the station 
acknowledging receipt, spoken three times;
    (5) The word RECEIVED (or RRR spoken as ROMEO ROMEO ROMEO in case of 
language difficulties);
    (6) The distress signal MAYDAY.
    (d) The acknowledgement by direct-printing telegraphy of receipt of 
a distress alert from a ship station must be given in the following 
form:
    (1) The distress signal MAYDAY;
    (2) The call sign or other identification of the station sending the 
distress alert;
    (3) The word DE;
    (4) The call sign or other identification of the station 
acknowledging receipt of the distress alert;
    (5) The signal RRR;
    (6) The distress signal MAYDAY.
    (e) The acknowledgement by direct-printing telegraphy of receipt of 
a distress alert from a ship earth station must be given by the coast 
earth station receiving the distress alert by retransmitting the ship 
station identity of the ship transmitting the distress alert.

[57 FR 9065, Mar. 16, 1992, as amended at 68 FR 46980, Aug. 7, 2003; 73 
FR 4491, Jan. 25, 2008; 76 FR 67618, Nov. 2, 2011]



Sec.  80.1119  Receipt and acknowledgement of distress alerts 
by coast stations and coast earth stations.

    (a) Coast stations that receive a distress alert should defer 
acknowledgement for a short interval so that receipt may be acknowledged 
by a Rescue Coordination Center. Where an acknowledgement is not 
forthcoming within 3 minutes, the coast station in receipt of distress 
alerts must ensure that they are routed to a Rescue Coordination Center 
as soon as possible. Coast stations must provide assistance for distress 
communications when requested to do so by the U.S. Coast Guard. (This 
subpart does not specify any radio watches for coast stations.)
    (b) Coast earth stations in receipt of distress alerts must ensure 
that they are routed as soon as possible to a Rescue Coordination 
Center. Coast earth stations must relay, as soon as possible, an 
acknowledgement of a distress alert from a Rescue Coordination Center.
    (c) Certain messages must be carried without charge, regardless of 
the means by which they are transmitted:
    (1) Distress alert messages;
    (2) Search and rescue coordination messages;
    (3) Medical assistance messages where an imminent danger to life is 
present, or
    (4) Urgent meteorological or navigational danger messages passed in 
the ship-to-shore direction.



Sec.  80.1121  Receipt and acknowledgement of distress alerts by ship stations 
and ship earth stations.

    (a) Ship or ship earth stations that receive a distress alert must, 
as soon as possible, inform the master or person responsible for the 
ship of the contents of the distress alert.
    (b) For VHF and MF, ships in receipt of a distress alert shall not 
transmit a distress alert relay, but should listen on the distress 
traffic channel for 5 minutes and, if appropriate, acknowledge the alert 
by radiotelephony to the ship in distress and inform the coast station 
and/or Rescue Coordination Center. Distress alert relays to ``all 
ships'' on these bands may only be sent by a ship who has knowledge that 
another ship in distress is not itself able to transmit the distress 
alert, and the Master of the ship considers that further help is 
necessary.
    (c) For HF, ships in receipt of a distress alert shall listen on the 
distress

[[Page 168]]

traffic channel for 5 minutes. If no distress communications are heard 
and if the call is not acknowledged by a coast station, the ship shall 
transmit a distress relay on HF to the coast radio station and inform 
the Rescue Coordination Center. Distress alert relays to ``all Ships'' 
on HF may only be sent by a ship who has knowledge that another ship in 
distress is not itself able to transmit the distress alert, and the 
Master of the ship considers that further help is necessary.
    (d) In cases where distress alert continues to be received from the 
same source, the ship may, after consultation with the Rescue 
Coordination Center, transmit a DSC acknowledgment to terminate the 
call.
    (e) A ship station in receipt of a shore-to-ship distress alert 
relay (see Sec.  80.1113(e)) should establish communication as directed 
and render such assistance as required and appropriate.

[57 FR 9065, Mar. 16, 1992, as amended at 68 FR 46980, Aug. 7, 2003]



Sec.  80.1123  Watch requirements for ship stations.

    (a) While at sea, all ships must maintain a continuous watch:
    (1) On VHF DSC channel 70, if the ship is fitted with a VHF radio 
installation in accordance with Sec.  80.1085(a)(2);
    (2) On the distress and safety DSC frequency 2187.5 kHz, if the ship 
is fitted with an MF radio installation in accordance with Sec.  
80.1089(a)(2) or Sec.  80.1091(a)(3);
    (3) On the distress and safety DSC frequencies 2187.5 kHz and 8414.5 
kHz also on at least one of the distress and safety DSC frequencies 
4207.5 kHz, 6312 kHz, 12577 kHz, or 16804.5 kHz appropriate to the time 
of day and the geographical position of the ship, if the ship is fitted 
with an MF/HF radio installation in accordance with Sec.  
80.1091(a)(2)(ii) or Sec.  80.1093(a) of this part (this watch may be 
kept by means of a scanning receiver limited to six distress and safety 
DSC frequencies); and
    (4) For satellite shore-to-ship distress alert, if the ship is 
fitted with an INMARSAT ship earth station in accordance with Sec.  
80.1091(a)(1).
    (b) While at sea, all ships must maintain radio watches for 
broadcasts of maritime safety information on the appropriate frequency 
or frequencies on which such information is broadcast for the area in 
which the ship is navigating.
    (c) Every ship while at sea must maintain, when practicable, a 
continuous listening watch on VHF Channel 16. This watch must be kept at 
the position from which the ship is normally navigated or at a position 
which is continuously manned.
    (d) On receipt of a distress alert transmitted by use of digital 
selective calling techniques, ship stations must set watch on the 
radiotelephone distress and safety traffic frequency associated with the 
distress and safety calling frequency on which the distress alert was 
received.
    (e) Ship stations with narrow-band direct printing equipment must 
set watch on the narrow-band direct-printing frequency associated with 
the distress alert signal if it indicates that narrow-band direct-
printing is to be used for subsequent distress communications. If 
practicable, they should additionally set watch on the radiotelephone 
frequency associated with the distress alert frequency.

    (a) The distress signal consists of the word MAYDAY, pronounced in 
radiotelephony as the French expression ``M'aider''. For distress 
traffic by radiotelephony, when establishing communications, calls must 
be prefixed by the distress signal MAYDAY.
    (b) Error correction techniques, in accordance with ITU-R M.625-3 
(incorporated by reference, see Sec.  80.7), as specified in Sec.  
80.1101, must be used for distress traffic by direct-printing 
telegraphy. All messages must be preceded by at least one carriage 
return, a line feed signal, a letter shift signal and the distress 
signal MAYDAY.
    (c) Distress communications by direct-printing telegraphy should be 
in the ARQ mode when ships are communicating directly to the Coast Guard 
or other coast stations on channels which

[[Page 169]]

they normally guard. Other distress communications, including those on 
simplex channels provided for that purpose, should be in the broadcast 
forward error correction mode. The ARQ mode may subsequently be used 
when it is advantageous to do so.
    (d) The Rescue Coordination Center responsible for controlling a 
search and rescue operation will also coordinate the distress traffic 
relating to the incident or may appoint another station to do so.
    (e) The Rescue Coordination Center coordinating distress traffic, 
the unit coordinating search and rescue operations, or the coast station 
involved may impose silence on stations which interfere with that 
traffic. This instruction may be addressed to all stations or to one 
station only, according to circumstances. In either case, the following 
will be used:
    (1) In radiotelephony, the signal SEELONCE MAYDAY, pronounced as the 
French expression ``silence, m'aider'';
    (2) In narrow-band direct-printing telegraphy normally using 
forward-error correcting mode, the signal SILENCE MAYDAY. However, the 
ARQ mode may be used when it is advantageous to do so.
    (f) Until they receive the message indicating that normal working 
may be resumed (see paragraph (h) of this section), all stations which 
are aware of the distress traffic, and which are not taking part in it, 
and which are not in distress, are forbidden to transmit on the 
frequencies in which the distress traffic is taking place.
    (g) Stations following distress traffic that are able to continue 
normal service may do so when the distress traffic is well established 
and on condition that it observes the provisions of paragraph (f) of 
this section and that it does not interfere with distress traffic.
    (h) When distress traffic has ceased on frequencies which have been 
used for distress traffic, the Rescue Coordination Center controlling a 
search and rescue operation must initiate a message for transmission on 
these frequencies indicating that distress traffic has finished.
    (i) In radiotelephony, the message referred to in paragraph (h) of 
this section consists of:
    (1) The distress signal MAYDAY;
    (2) The call ``Hello all stations'' or CQ (spoken as CHARLIE QUEBEC) 
spoken three times;
    (3) The words THIS IS (or DE spoken as DELTA ECHO in the case of 
language difficulties);
    (4) The call sign or other identification of the station sending the 
message;
    (5) The time when the distress situation has ceased;
    (6) The name and call sign of the mobile station which was in 
distress;
    (7) The words SEELONCE FEENEE pronounced as the French words 
``silence fini''
    (j) In direct-printing telegraphy, the message referred to in 
paragraph (h) of this section consists of:
    (1) The distress signal MAYDAY;
    (2) The call CQ;
    (3) The word DE;
    (4) The call sign or other identification of the station sending the 
message;
    (5) The time when distress situation has ceased;
    (6) The name and call sign of the mobile station which was in 
distress; and
    (7) The words SILENCE FINI.

    (a) On-scene communications are those between mobile unit in 
distress and assisting mobile units, and between the mobile units and 
unit coordinating search and rescue operations.
    (b) Control of on-scene communications is the responsibility of the 
unit coordinating search and rescue operations. Simplex communications 
must be used so that all on-scene mobile stations may share relevant 
information concerning the distress incident. If direct-printing 
telegraphy is used, it must be in the forward error-correcting mode in 
accordance with ITU-R Recommendation M.625-3, with Annex, as specified 
in Sec.  80.1101.
    (c) The preferred frequencies in radiotelephony for on-scene 
communications are 156.8 MHz and 2182 kHz.

and all ground stations the attenuation must be at least 43 + 10 
log10pY dB.
    (e) When using frequency modulation or digital modulation for 
telemetry or telecommand in the 1435-1525 MHz, 2345-2395 MHz, or 5091-
5150 MHz band with an authorized bandwidth equal to or less than 1 MHz 
the emissions must be attenuated as follows:
    (1) On any frequency removed from the assigned frequency by more 
than 100 percent of the authorized bandwidth up to and including 100 
percent plus 0.5 MHz, the attenuation must be at least 60 dB, when 
measured in a 3.0 kHz bandwidth. This signal need not be attenuated more 
than 25 dB below 1 milliwatt.
    (2) On any frequency removed from the assigned frequency by more 
than 100 percent of the authorized bandwidth plus 0.5 MHz, the 
attenuation must be at least 55 + 10 log10 pY dB when 
measured in a 3.0 kHz bandwidth.
    (f) When using frequency modulation or digital modulation for 
telemetry or telecommand in the 1435-1525 MHz, 2345-2395 MHz, or 5091-
5150 MHz band with an authorized bandwidth greater than 1 MHz, the 
emissions must be attenuated as follows:
    (1) On any frequency removed from the assigned frequency by more 
than 50 percent of the authorized bandwidth plus 0.5 MHz up to and 
including 50 percent of the authorized bandwidth plus 1.0 MHz, the 
attenuation must be 60 dB, when measured in a 3.0 kHz bandwidth. The 
signal need not be attenuated more than 25 dB below 1 milliwatt.
    (2) On any frequency removed from the assigned frequency by more 
than 50 percent of the authorized bandwidth plus 1.0 MHz, the 
attenuation must be at least 55 + 10 log10 pY dB, when 
measured in a 3.0 kHz bandwidth.
    (g) The requirements of paragraphs (e) and (f) of this section apply 
to transmitters approved after January 1, 1977, and to all transmitters 
first installed after January 1, 1983.
    (h) For ELTs operating on 121.500 MHz, 243.000 MHz and 406.0-406.1 
MHz the mean power of any emission must be attenuated below the mean 
power of the transmitter (pY) as follows:
    (1) When the frequency is moved from the assigned frequency by more 
than 50 percent up to and including 100 percent of the authorized 
bandwidth the attenuation must be at least 25 dB;
    (2) When the frequency is removed from the assigned frequency by

    (i) In case of conflict with other provisions of Sec.  87.139, the 
provisions of this paragraph shall govern for aircraft earth stations. 
When using G1D, G1E, or G1W emissions in the 1646.5-1660.5 MHz frequency 
band, the emissions must be attenuated as shown below.
    (1) At rated output power, while transmitting a modulated single 
carrier, the composite spurious and noise output shall be attenuated by 
at least:

------------------------------------------------------------------------
              Frequency (MHz)                   Attenuation (dB) \1\

12000 to 18000............................  -70 dB/4 kHz
------------------------------------------------------------------------
\1\ These values are expressed in dB referenced to the carrier for the
  bandwidth indicated, and relative to the maximum emission envelope
  level, except where the attenuation is shown in dBW, the attenuation
  is expressed in terms of absolute power referenced to the bandwidth
  indicated.
\2\ Attenuation measured within the transmit band excludes the band
  35 kHz of the carrier frequency.
\3\ This level is not applicable for intermodulation products.

[[Page 192]]

 
\4\ The upper limit for the excess power for any narrow-band spurious
  emission (excluding intermodulation products within a 30 kHz
  measurement bandwidth) shall be 10 dB above the power limit in this
  table.

    (2) The transmitter emission limit is a function of the modulation 
type and symbol rate (SR). Symbol Rate is expressed in symbols per 
second.
    (3) While transmitting a single modulated signal at the rated output 
power of the transmitter, the emissions must be attenuated below the 
maximum emission level by at least:

------------------------------------------------------------------------
                                                             Attenuation
            Frequency Offset (normalized to SR)                  (dB)
------------------------------------------------------------------------
0.75 x SR............................            0
1.40 x SR............................           20
2.95 x SR............................           40
------------------------------------------------------------------------

Where:

SR = Symbol Rate,
SR = 1 x channel rate for BPSK,
SR = 0.5 x channel rate for QPSK.

    The mask shall be defined by drawing straight lines through the 
above points.
    (j) When using G7D for differential GPS in the 112-118 MHz band, the 
amount of power during transmission under all operating conditions when 
measured over a 25 kHz bandwidth centered on either of the second 
adjacent channels shall not exceed -25 dBm and shall decrease 5 dB per 
octave until -52 dBm.
    (k) For VHF aeronautical stations and aircraft stations operating 
with G1D or G7D emissions:
    (1) The amount of power measured across either first adjacent 25 kHz 
channel shall not exceed 2 dBm.

of power measured across either second adjacent channel shall be less 
than -25 dBm and the power measured in any other adjacent 25 kHz 
channels shall monotonically decrease at a rate of at least 5 dB per 
octave to a maximum value of -52 dBm. For stations first installed on or 
after January 1, 2002,

kHz channel shall be less than -28 dBm;
    (ii) The amount of power measured across either fourth adjacent 25 
kHz channel shall be less than -38 dBm; and
    (iii) From thereon the power measured in any other adjacent 25 kHz 
channel shall monotonically decrease at a rate of at least 5 dB per 
octave to a maximum value of -53 dBm.
    (3) The amount of power measured over a 16 kHz channel bandwidth 
centered on the first adjacent 25 kHz channel shall not exceed -18 dBm.
    (l)(1) For Universal Access Transceiver transmitters, the average 
emissions measured in a 100 kHz bandwidth must be attenuated below the 
maximum emission level contained within the authorized bandwidth by at 
least:

------------------------------------------------------------------------
                                                             Attenuation
                      Frequency (MHz)                           (dB)
------------------------------------------------------------------------
0.5.................................             0
1.0.................................            18
2.25................................            50

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

    (2) Universal Access Transceiver transmitters with an output power 
of 5 Watts or more must limit their emissions by at least 43 + 10 log 
(P) dB on any frequency removed from the assigned frequency by more than 
250% of the authorized bandwidth. Those emissions shall be measured with 
a bandwidth of 100 kHz. P in the above equation is the average 
transmitter power measured within the occupied bandwidth in Watts.
    (3) Universal Access Transceiver transmitters with less than 5 Watts 
of output power must limit their emissions by at least 40 dB relative to 
the carrier peak on any frequency removed from the assigned frequency by 
more than 250% of the authorized bandwidth. Those emissions shall be 
measured with a bandwidth of 100 kHz.
    (m) In the 1435-1452 MHz band, operators of aeronautical telemetry 
stations are encouraged to take all reasonable steps to ensure that 
unwanted emissions power does not exceed -28 dBW/27 MHz in the 1400-1427 
MHz band. Operators of aeronautical telemetry stations that do not meet 
this limit shall first attempt to operate in the 1452-1525 MHz band 
prior to operating in the 1435-1452 MHz band.

Sec.  87.141  Modulation requirements.

    (a) When A3E emission is used, the modulation percentage must not 
exceed 100 percent. This requirement does not apply to emergency locator 
transmitters or survival craft transmitters.
    (b) A double sideband full carrier amplitude modulated 
radiotelephone transmitter with rated carrier power output exceeding 10 
watts must be capable of automatically preventing modulation in excess 
of 100 percent.
    (c) If any licensed radiotelephone transmitter causes harmful 
interference to any authorized radio service because of excessive 
modulation, the Commission will require the use of the transmitter to be 
discontinued until it is rendered capable of automatically preventing 
modulation in excess of 100 percent.
    (d) Single sideband transmitters must be able to operate in the 
following modes:

------------------------------------------------------------------------
                                        Level N(dB) of the carrier with
             Carrier mode                respect to peak envelope power
------------------------------------------------------------------------
Full carrier (H3E)...................  ON-6.
Suppressed carrier (J3E).............  Aircraft stations N<-26;
                                       Aeronautical stations N<-40.
------------------------------------------------------------------------

    (e) Each frequency modulated transmitter operating in the band 72.0-
76.0 MHz must have a modulation limiter.
    (f) Each frequency modulated transmitter equipped with a modulation 
limiter must have a low pass filter between the modulation limiter and 
the modulated stage. At audio frequencies between 3 kHz and 15 kHz, the 
filter must have an attenuation greater than the attenuation at 1 kHz by 
at least 40 log10 (f/3) db where ``f'' is the frequency in 
kilohertz. Above 15 kHz, the attenuation must be at least 28 db greater 
than the attenuation at 1 kHz.
    (g) Except that symmetric side bands are not required, the 
modulation characteristics for ELTs must be in accordance with 
specifications contained in the Federal Aviation Administration (FAA) 
Technical Standard Order (TSO) Document TSO-C91a titled ``Emergency 
Locator Transmitter (ELT) Equipment'' dated April 29, 1985. TSO-C91a is 
incorporated by reference in accordance with 5 U.S.C. 552(a). TSO-C91a 
may be obtained from the Department of Transportation, Federal Aviation 
Administration, Office of Airworthiness, 800 Independence Avenue SW., 
Washington DC 20591.
    (h) ELTs must use A3X emission and may use A3E or NON emissions on 
an optional basis while transmitting. Each transmission of a synthesized 
or recorded voice message from an ELT must be preceded by the words 
``this is a recording''; transmission of A3E or NON emission must not 
exceed 90 seconds; and any transmission of A3E or NON emissions must be 
followed by at least three minutes of A3X emission.
    (i) ELTs manufactured on or after October 1, 1988, must have a 
clearly defined carrier frequency distinct from the modulation sidebands 
for the mandatory emission, A3X, and, if used, the A3E or NON emissions. 
On 121.500 MHz at least thirty per cent of the total power emitted 
during any transmission cycle with or without modulation must be 
contained within plus or minus 30 Hz of the carrier frequency. On 
243.000 MHz at least thirty percent of the total power emitted during 
any transmission cycle with or without modulation must be contained 
within plus or minus 60 Hz of the carrier frequency. Additionally, if 
the type of emission is changed during transmission, the carrier 
frequency must not shift more than plus or minus 30 Hz on 121.500 MHz 
and not more than plus or minus 60Hz on 243.000 MHz. The long term 
stability of the carrier frequency must comply with the requirements in 
Sec.  87.133 of this part.
    (j) Transmitters used at Aircraft earth stations must employ BPSK 
for transmission rates up to and including 2400 bits per second, and 
QPSK for higher rates.
    (k) Universal Access Transceiver transmitters must use F1D 
modulation without phase discontinuities.

Sec.  87.143  Transmitter control requirements.

    (a) Each transmitter must be installed so that it is not accessible 
to, or capable of being operated by persons other than those authorized 
by the licensee.

[[Page 194]]

    (b) Each station must be provided with a control point at the 
location of the transmitting equipment, unless otherwise specifically 
authorized. Except for aeronautical enroute stations governed by 
paragraph (e) of this section, a control point is the location at which 
the radio operator is stationed. It is the position at which the 
transmitter(s) can immediately be turned off.
    (c) Applicants for additional control points at aeronautical 
advisory (unicom) stations must specify the location of each proposed 
control point.
    (d) Except for aeronautical enroute stations governed by paragraph 
(f) of this section, the control point must have the following 
facilities installed:
    (1) A device that indicates when the transmitter is radiating or 
when the transmitter control circuits have been switched on. This 
requirement does not apply to aircraft stations;
    (2) Aurally monitoring of all transmissions originating at dispatch 
points;
    (3) A way to disconnect dispatch points from the transmitter; and
    (4) A way to turn off the transmitter.
    (e) A dispatch point is an operating position subordinate to the 
control point. Dispatch points may be installed without authorization 
from the Commission, and dispatch point operators are not required to be 
licensed.
    (f) In the aeronautical enroute service, the control point for an 
automatically controlled enroute station is the computer facility which 
controls the transmitter. Any computer controlled transmitter must be 
equipped to automatically shut down after 3 minutes of continuous 
transmission of an unmodulated carrier.



Sec.  87.145  Acceptability of transmitters for licensing.

    (a) Each transmitter must be certificated for use in these services, 
except as listed in paragraph (c) of this section. However, aircraft 
stations which transmit on maritime mobile frequencies must use 
transmitters certificated for use in ship stations in accordance with 
part 80 of this chapter. Certification under part 80 is not required for 
aircraft earth stations transmitting on maritime mobile-satellite 
frequencies. Such stations must be certificated under part 87.
    (b) Some radio equipment installed on air carrier aircraft must meet 
the requirements of the Commission and the requirements of the FAA. The 
FAA requirements may be obtained from the FAA, Aircraft Maintenance 
Division, 800 Independence Ave., SW., Washington, DC 20591.
    (c) The equipment listed below is exempted from certification. The 
operation of transmitters which have not been certificated must not 
result in harmful interference due to the failure of those transmitters 
to comply with technical standards of this subpart.
    (1) Flight test station transmitters for limited periods where 
justified.
    (2) U.S. Government transmitters furnished in the performance of a 
U.S. Government contract if the use of certificated equipment would 
increase the cost of the contract or if the transmitter will be 
incorporated in the finished product. However, such equipment must meet 
the technical standards contained in this subpart.
    (3) ELTs verified in accordance with Sec.  87.147(e).
    (4) Signal generators when used as radionavigation land test 
stations (MTF).
    (d) Aircraft earth stations must correct their transmit frequencies 
for Doppler effect relative to the satellite. The transmitted signal may 
not deviate more than 335 Hz from the desired transmit frequency. (This 
is a root sum square error which assumes zero error for the received 
ground earth station signal and includes the AES transmit/receive 
frequency reference error and the AES automatic frequency control 
residual errors.) The applicant must attest that the equipment provides 
adequate Doppler effect compensation and where applicable, that 
measurements have been made that demonstrate compliance. Submission of 
data demonstrating compliance is not required unless requested by the 
Commission.

Sec.  87.147  Authorization of equipment.

    (a) Certification may be requested by following the procedures in 
part 2 of this chapter. Aircraft transmitters

[[Page 195]]

must meet the requirements over an ambient temperature range of -20 
degrees to + 50 degrees Celsius.
    (b) ELTs manufactured after October 1, 1988, must meet the output 
power characteristics contained in Sec.  87.141(i). A report of the 
measurements must be submitted with each application for certification. 
ELTs that meet the output power characteristics of the section must have 
a permanent label prominently displayed on the outer casing state, 
``Meets FCC Rule for improved satellite detection.'' This label, 
however, must not be placed on the equipment without authorization to do 
so by the Commission. Application for such authorization may be made 
either by submission of a new application for certification accompanied 
by the required fee and all information and test data required by parts 
2 and 87 of this chapter or, for ELTs approved prior to October 1, 1988, 
a letter requesting such authorization, including appropriate test data 
and a showing that all units produced under the original equipment 
authorization comply with the requirements of this paragraph without 
change to the original circuitry.
    (c) An applicant for a station license may request certification for 
an individual transmitter by following the procedure in part 2 of this 
chapter. Such a transmitter will be individually certified and so noted 
on the station license.
    (d) An applicant for certification of equipment intended for 
transmission in any of the frequency bands listed in paragraph (d)(3) of 
this section must notify the FAA of the filing of a certification 
application. The letter of notification must be mailed to: FAA, Office 
of Spectrum Policy and Management, ASR-1, 800 Independence Ave., SW., 
Washington, DC 20591 prior to the filing of the application with the 
Commission.
    (1) The notification must describe the equipment, give the 
manufacturer's identification, antenna characteristics, rated output 
power, emission type and characteristics, the frequency or frequencies 
of operation, and essential receiver characteristics if protection is 
required.
    (2) The certification application must include a copy of the 
notification letter to the FAA. The Commission will not act until it 
receives the FAA's determination regarding whether it objects to the 
application for equipment authorization. The FAA should mail its 
determination to: Office of Engineering and Technology Laboratory, 
Authorization and Evaluation Division, 7435 Oakland Mills Rd., Columbia, 
MD 21046. The Commission will consider the FAA determination before 
taking final action on the application.
    (3) The frequency bands are as follows:

90-110 kHz
190-285 kHz
325-435 kHz

31.800 GHz to 33.400 GHz

    (e) Supplier's Declaration of Conformity for ELTs capable of 
operating on the frequency 406.0-406.1 MHz must include sufficient 
documentation to show that the ELT meets the requirements of Sec.  
87.199(a). A letter notifying the FAA of the ELT Supplier's Declaration 
of Conformity must be mailed to: FAA, Office of Spectrum Policy and 
Management, ASR-1, 800 Independence Avenue SW., Washington, DC 20591.
    Note 1 to paragraph (e): The verification procedure has been 
replaced by Supplier's Declaration of Conformity. Equipment previously 
authorized under subpart J of part 2 of this chapter may remain in use. 
See Sec.  2.950 of this chapter.
    (f) Certification may be requested for equipment that has the 
capability to transmit in the 138-144 MHz, 148-149.9 MHz, or 150.5-150.8 
MHz bands as well as frequency bands set forth in Sec.  87.173. The 
Commission will only certify this equipment for use in the bands 
regulated by this part.

    (b) The aircraft receiving antenna can be horizontally or vertically 
polarized. Due to the difference in the signal strength of horizontally 
and vertically polarized components of the broadcast signal, the total 
aircraft implementation loss is limited to 15 dB for horizontally 
polarized receiving antennas and 11 dB for vertically polarized 
receiving antennas.

    (d) Intermodulation immunity. The receiver shall meet the 
requirements specified in paragraph (a) of this section in the presence 
of interference from two-signal, third order intermodulation products of 
two VHF-FM broadcast signals having levels in accordance with the 
following:
    (1) 2N1 + N2 + 72 <=0 for VHF-FM sound 
broadcasting signals in the range 107.7-108 MHz; and
    (2) 2N1 + N2 + 3 (24 -20log delta f/0.4) <=0 
for VHF-FM sound broadcasting signals below 107.7 MHz, where the 
frequencies of the two VHF-FM sound broadcasting signals produce, within 
the receiver, a two signal, third-order intermodulation product on the 
desired VDB frequency.
    (3) In the formulas in paragraphs (d)(1) and (d)(2) of this section, 
N1 and N2 are the levels (dBm) of the two VHF FM 
sound broadcasting signals at the VHF data broadcast (VDB) receiver 
input. Neither level shall exceed the desensitization criteria set forth 
in paragraph (c) of this section. Delta f = 108.1 - f1, where f1 is the 
frequency of N1, the VHF FM sound broadcasting signal closer 
to 108.1 MHz.

           Subpart G_Aeronautical Advisory Stations (Unicoms)



Sec.  87.213  Scope of service.

    (a) An aeronautical advisory station (unicom) must provide service 
to any aircraft station upon request and without discrimination. A 
unicom must provide impartial information concerning available ground 
services.
    (b)(1) Unicom transmissions must be limited to the necessities of 
safe and expeditious operation of aircraft such as condition of runways, 
types of fuel available, wind conditions, weather information, 
dispatching, or other necessary information. At any airport at which a 
control tower, control tower remote communications outlet station (RCO) 
or FAA flight service station is located, unicoms must not transmit 
information pertaining to the conditions of runways, wind conditions, or 
weather information during the hours of operation of the control tower, 
RCO or FAA service station.
    (2) On a secondary basis, unicoms may transmit communications which 
pertain to the efficient portal-to-portal transit of an aircraft, such 
as requests for ground transportation, food or lodging.
    (3) Communications between unicoms and air carrier must be limited 
to the necessities of safety of life and property.
    (4) Unicoms may communicate with aeronautical utility stations and 
ground vehicles concerning runway conditions and safety hazards on the 
airport when neither a control tower nor FAA flight service station is 
in operation.
    (c) Unicoms must not be used for air traffic control (ATC) purposes 
other than to relay ATC information between the pilot and air traffic 
controller. Relaying of ATC information is limited to the following:
    (1) Revisions of proposed departure time;
    (2) Takeoff, arrival or flight plan cancellation time;
    (3) ATC clearances, provided a letter of agreement is obtained from 
the FAA by the licensee of the unicom.

[[Page 208]]



Sec.  87.215  Supplemental eligibility.

    (a) A unicom and any associated dispatch or control points must be 
located on the airport to be served.
    (b) Only one unicom will be authorized to operate at an airport 
which does not have a control tower, RCO or FAA flight service station 
that operates on the published common traffic advisory frequency. At any 
other airport, the one unicom limitation does not apply, and the airport 
operator and all aviation services organizations may be licensed to 
operate a unicom on the assigned frequency.
    (c) At an airport where only one unicom may be licensed, eligibility 
for new unicom licenses is restricted to State or local government 
entities, and to nongovernmental organizations (NGOs) that are 
authorized to apply for the license by a State or local government 
entity whose primary mission is the provision of public safety services. 
All applications submitted by NGOs must be accompanied by a new, written 
certification of support (for the NGO applicant to operate the applied 
for station) by the state or local government entity. Applications for a 
unicom license at the same airport, where only one unicom may be 
licensed, that are filed by two or more applicants meeting these 
eligibility criteria must be resolved through settlement or technical 
amendment.
    (d) At an airport where only one unicom may be licensed, the license 
may be assigned or transferred only to an entity meeting the 
requirements of paragraph (c) of this section.
    (e) An applicant for renewal of a unicom license shall be granted a 
presumptive renewal expectancy regardless of whether the applicant is 
eligible for a new unicom license under paragraph (c) of this section. 
Unless the renewal expectancy is defeated, applications that are 
mutually exclusive with the renewal application will not be accepted. 
The renewal expectancy may be defeated only upon a determination, 
following a hearing duly designated on the basis of a petition to deny 
or on the Commission's own motion, that the renewal applicant has not 
provided substantial service. For purposes of this paragraph, 
substantial service means service which is sound, favorable, and 
substantially above a level of mediocre service during the applicant's 
past license term. If the renewal expectancy is defeated, the renewal 
application will be dismissed unless the renewal applicant is eligible 
for a new unicom license pursuant to paragraph (c) of this section.
    (f) At an airport where only one unicom may be licensed, when the 
Commission believes that the unicom has been abandoned or has ceased 
operation, another unicom may be licensed on an interim basis pending 
final determination of the status of the original unicom. An applicant 
for an interim license must notify the present licensee and must comply 
with the notice requirements of paragraph (g) of this section.
    (g) An applicant for a unicom license, renewal or modification of 
frequency assignment at an airport which does not have a control tower, 
RCO or FAA flight service station must notify in writing the owner of 
the airport and all aviation service organizations located at the 
airport. The notice must include the applicant's name and address, the 
name of the airport and a statement that the applicant intends to file 
an application with the Commission for a unicom. The notice must be 
given within the ten days preceding the filing of the application with 
the Commission. Each applicant must certify upon application that either 
notice has been given and include the date of notification, or notice is 
not required because the applicant owns the airport and there are no 
organizations that should be notified.

Sec.  87.219  Automatic operations.

    (a) A station operator need not be present when an automated unicom 
is in operation.
    (b) Unicoms operating in an automated mode must comply with the 
requirements of paragraphs (1)-(5) of this section, in addition to the 
requirements applicable to non-automated unicom operations.
    (1) An automated unicom must transmit only in response to 
interrogating signals from aircraft, including but not limited to the 
brief keyed RF signals specified in Sec.  87.187(y).
    (2) An automated unicom must monitor the unicom frequency prior to 
transmission, and provide a brief delay between the aircraft's 
interrogating signal and the automatic unicom's response.
    (3) Automated advisory transmissions must be as brief as possible, 
and must never exceed one minute in length.
    (4) An automated unicom may not provide weather information at an 
airport that has an operational, FAA-certified, automatic weather 
facility, unless the unicom itself is certified by the FAA.
    (5) If weather information is provided by an automated unicom:
    (i) Weather sensors must be placed in order to adequately represent 
the weather conditions at the airport(s) to be served;
    (ii) The weather information must be proceeded by the word 
``advisory;''
    (iii) The phrase ``automated advisory'' must be included when the 
weather information was gathered by real-time sensors or within the last 
minute; and,
    (iv) The time and date of the last update must be included when the 
weather information was not gathered within the last minute.
    (c) Only one automated unicom may be operated at an uncontrolled 
airport. Prior to the operation of an automated unicom at an airport 
with more than one unicom licensee, all of the licensees at that airport 
must sign a letter of agreement stating which licensee(s) control the 
automated unicom operations, and, if control is to be shared among 
several operators, how that control will be divided or scheduled. The 
original or a copy of the letter of agreement must be kept with each 
licensees' station records. Within 90 days of the date upon which a new 
unicom operator is licensed at an airport where more than one unicom is 
authorized, and an automated unicom is being operated, an amended letter 
of agreement that includes the new licensee's signature must be signed 
or automated unicom operations must cease.

Sec.  87.237  Scope of service.

    (a) The communications of an aeronautical multicom station 
(multicom) must pertain to activities of a temporary, seasonal or 
emergency nature involving aircraft in flight. Communications are 
limited to directing or coordinating ground activities from the air or 
aerial activities from the ground. Air-to-air communications will be 
authorized if the communications are directly connected with the air-to-
ground or ground-to-air activities described above. Multicom 
communications must not include those air/ground communications provided 
for elsewhere in this part.
    (b) If there is not unicom and an applicant is unable to meet the 
requirements for a unicom license, the applicant will be eligible for a 
multicom license.
    (1) The multicom license becomes invalid when a unicom is 
established at the landing area.
    (2) Multicoms must not be used for ATC purposes other than the relay 
of ATC information between the pilot and air traffic controller. 
Relaying of ATC information is limited to the following:
    (i) Revisions of proposed departure time;

[[Page 210]]

    (ii) Takeoff, arrival flight plan cancellation time;
    (iii) ATC clearances, provided a letter of agreement is obtained 
from the FAA by the licensee of the multicom.
    (3) Communications by a multicom must be limited to the safe and 
expeditious operation of private aircraft, pertaining to the conditions 
of runways, types of fuel available, wind conditions, weather 
information, dispatching or other information. On a secondary basis, 
multicoms may transmit communictions which pertain to efficient portal-
to-portal transit of an aircraft such as requests for ground 
transportation, food or lodging.



Sec.  87.239  Supplemental eligibility.

    Each applicant for a multicom may be required to demonstrate why 
such a station is necessary, based on the scope of service defined 
above.

                      Aeronautical Enroute Stations



Sec.  87.261  Scope of service.

    (a) Aeronautical enroute stations provide operational control 
communications to aircraft along domestic or international air routes. 
Operational control communications include the safe, efficient and 
economical operation of aircraft, such as fuel, weather, position 
reports, aircraft performance, and essential services and supplies. 
Public correspondence is prohibited.
    (b) Service must be provided to any aircraft station licensee who 
makes cooperative arrangements for the operation, maintenance and 
liability of the stations which are to furnish enroute service. In 
emergency or distress situations service must be provided without prior 
arrangements.
    (c) Except in Alaska, only one aeronautical enroute station licensee 
will be authorized at any one location. In Alaska, only one aeronautical 
enroute station licensee in the domestic service and one aeronautical 
enroute station licensee in the international service will be authorized 
at any one location. (Because enroute stations may provide service over 
a large area containing a number of air routes or only provide 
communications in the local area of an airport, location here means the 
area which can be adequately served by the particular station.)
    (d) In Alaska, only stations which serve scheduled air carriers will 
be licensed to operate aeronautical enroute stations. Applicants must 
show that the station will provide communications only along routes 
served by scheduled air carriers.
    (e) Mobile units may be operated under an aeronautical enroute 
station authorization so long as the units are limited to use at an 
airport and are only used to communicate with aircraft on the ground or 
the associated aeronautical enroute station. Mobile units are further 
limited to operation on the VHF frequencies listed in 87.263(a)(1).
    (f) Mobile units licensed under paragraph (e) of this section shall 
not be operated on air traffic control frequencies, nor cause harmful 
interference to, communications on air traffic control frequencies.

Sec.  87.265  Administrative communications.

    Domestic VHF aeronautical enroute stations authorized to use A9W 
emission on any frequency listed in Sec.  87.263(a)(1) or Sec.  
87.263(a)(3) may transmit digital administrative communications on a 
secondary basis, in addition to the operational and control 
communications routinely permitted under Sec.  87.261(a) above. Such 
secondary administrative communications must directly relate to the 
business of a participating aircraft operator in providing travel and 
transportation services to the flying public or to the travel, 
transportation or scheduling activities of the aircraft operator itself. 
Stations transmitting administrative communications must provide 
absolute priority for operational control and other safety 
communications by means of an automatic priority control system.

Sec.  87.275  Scope of service.

    Aeronautical fixed stations provide non-public point-to-point 
communications service pertaining to safety, regularity and economy of 
flight. These stations must transmit, without discrimination, messages 
from aircraft which have entered into cooperative arrangements governing 
the operation and maintenance of such stations. Aeronautical fixed 
station licensees are required to transmit, without charge or 
discrimination, all emergency communications.



Sec.  87.277  Supplemental eligibility.

    Aeronautical fixed station licenses will only be issued to the 
licensees of associated aeronautical enroute stations. Aeronautical 
fixed station licenses will not be issued where adequate land line 
facilities are available.

safety of life and property. This subpart is consistent with the 
Aeronautical Emergency Communications System Plan for all Aviation 
Services licensees of the Commission which was developed pursuant to 
sections 1, 4(o), 301 and 303 of the Communications Act, and Executive 
Order 11490, as amended. This Plan provides for emergency communications 
to meet the requirements of the Plan for the Security Control of Air 
Traffic and Air Navigation Aids (SCATANA), Civil Reserve Air Fleet 
(CRAF), War Air Service Program (WASP) and, where applicable, State and 
Regional Disaster Airlift Planning (SARDA).



Sec.  87.395  Plan for the Security Control of Air Traffic 
and Air Navigation Aids (Short Title: SCATANA).

    (a) The Plan for the Security Control of Air Traffic and Air 
Navigation Aids (SCATANA) is promulgated in furtherance of the Federal 
Aviation Act of 1958, as amended, the Communications Act and Executive 
Order 11490, as amended. SCATANA defines the responsibilities of the 
Commission for the security control of non-Federal air navigation aids.
    (b) Under the responsibilities defined in SCATANA, an FCC Support 
Plan for the Security Control of Non-Federal Air Navigation Aids has 
been developed by the Commission. The FCC Support Plan defines 
responsibilities, procedures, and instructions in consonance with 
SCATANA which will effect control of non-Federal air navigation aids 
when SCATANA is implemented. It permits the use of such navigation aids 
by aircraft of military and civil agencies when SCATANA is implemented. 
The FCC Support Plan highlights those parts of SCATANA which deal 
specifically with non-Federal air navigation aids. SCATANA and the FCC 
Support Plan apply to radionavigation stations authorized by the 
Commission in the following manner:
    (1) All licensees are subject to restrictions imposed by appropriate 
military authorities pursuant to SCATANA and the FCC Support Plan when 
an Air Defense Emergency or Defense Emergency exists or is imminent. The 
restrictions will be imposed through FAA Air Route Traffic Control 
Centers (ARTCCs).
    (2) All licensees of aeronautical radionavigation (VOR/DME, ILS, 
MLS, LF and MF non-directional beacons) stations will comply with 
SCATANA implementation instructions from FAA ARTCCs as follows:
    (i) Shut down the above navigation aids as directed. These 
instructions will permit time to land or disperse airborne aircraft, and 
will permit extension of time when the air traffic situation dictates.
    (ii) Shut down as soon as possible stations which require more than 
five minutes control time, unless directed otherwise or unless such 
stations are essential for the handling of existing air traffic.
    (iii) Operate aeronautical radionavigation stations to ensure that 
required stations, as indicated in flight plans, will be available for 
authorized aircraft flights.
    (3) Licensees of aeronautical radionavigation stations will be 
notified of the reduction or removal of SCATANA restrictions by FAA 
ARTCCs when notice of the termination is issued.
    (4) Licensees of aeronautical radionavigation stations may 
voluntarily participate in SCATANA tests as requested by an ARTCC. 
SCATANA testing must not interrupt the normal service of non-Federal air 
navigation aids.



Sec.  87.397  Emergency operations.

    (a) The licensee of any land station in the Aviation services, 
during a local emergency involving the safety of life and property may 
communicate in a manner other than that specified in the license (See 
Sec.  87.395). Such emergency operations may include operation at other 
locations or with equipment not specified in the license or by 
unlicensed personnel provided that:
    (1) Such operations are under the control and supervision of the 
station licensee,
    (2) The emergency use is discontinued as soon as practicable upon 
termination of the emergency,
    (3) In no event shall any station transmit on frequencies other than 
or with power in excess of that specified in the license,

[[Page 221]]

    (4) The details of the emergency must be retained with the station 
license, and
    (5) At a controlled airport these communications must be coordinated 
with the FAA.
    (b) The unicom frequencies listed in subpart G may also be used for 
communications with private aircraft engaged in organized civil defense 
activities in preparation for, during an enemy attack or immediately 
after an enemy attack. When used for these purposes, unicoms may be 
moved from place to place or operated at unspecified locations, except 
at landing areas served by other unicoms or control towers.
    (c) In any case in which a license for unattended operation has been 
granted, the Commission may at any time, for national defense, modify 
the license.



                Subpart O_Airport Control Tower Stations



Sec.  87.417  Scope of service.

    (a) Airport control tower stations (control towers) and control 
tower remote communications outlet stations (RCOs) must limit their 
communications to the necessities of safe and expeditious operations of 
aircraft operating on or in the vicinity of the airport. Control towers 
and RCOs provide air traffic control services to aircraft landing, 
taking off and taxing on the airport as well as aircraft transiting the 
airport traffic area. Additionally, control towers and RCOs can provide 
air traffic control services to vehicles operating on airport movement 
areas (see subpart L of this part). Control towers and RCOs must serve 
all aircraft without discrimination. An RCO must be remotely operated 
from a control tower or other FAA control facility located at a nearby 
airport.
    (b) A control tower must maintain a continuous watch on the 
following frequencies during the hours of operation:

121.500 MHz
3023.0 kHz (Alaska only)
5680.0 kHz (Alaska only)

    The Commission may exempt from these watch requirements the licensee 
of an airport control tower station if a satisfactory showing has been 
made that such an exemption will not adversely affect life and property 
in the air.

and RCOs at special aeronautical events on the condition that no harmful 
interference is caused to search and rescue operations in the locale 
involved.
    (b) Frequencies in the bands 200.0-285.0 and 325.0-405.0 kHz will 
normally be assigned only to control towers and RCOs authorized to 
operate on at least one VHF frequency. The Commission may assign 
frequencies in these bands to entities that do not provide VHF service 
in cases where granting such an application will not adversely affect 
life and property in the air.
    (c) Frequencies listed in the introductory paragraph of this section 
are available to control towers and RCOs for communications with ground 
vehicles and aircraft on the ground. The antenna heights shall be 
restricted to the minimum necessary to achieve the required coverage. 
Channel spacing is 25 kHz.

Sec.  87.479  Harmful interference to radionavigation land stations.

    (a) Military or other Government stations have been authorized to 
establish wide-band systems using frequency-hopping spread spectrum 
techniques in the 960-1215 MHz band. Authorization for a Joint Tactical 
Information Distribution Systems (JTIDS) has been permitted on the basis 
of non-interference to the established aeronautical radionavigation 
service in this band. In order to accommodate the requirements for the 
system within the band, restrictions are imposed. Transmissions will be 
automatically prevented if:
    (1) The frequency-hopping mode fails to distribute the JTIDS 
spectrum uniformly across the band;
    (2) The radiated pulse varies from the specified width of 6.4 
microseconds 5%;
    (3) The energy radiated within 7 MHz of 1030 
and 1090 MHz exceeds a level of 60 dB below the peak of the JTIDS 
spectrum as measured in a 300 kHz bandwidth. The JTIDS will be 
prohibited from transmitting if the time slot duty factor exceeds a 20 
percent duty factor for any single user and a 40 percent composite duty 
factor for all JTIDS emitters in a geographic area.
    (b) If radionavigation systems operating in the 960-1215 MHz band 
experience interference or unexplained loss of equipment performance, 
the situation must be reported immediately to the nearest office of the 
FAA, the National Telecommunications and Information Administration, 
Washington, DC 20504, or the nearest Federal Communications Commission 
field office. The following information must be provided to the extent 
available:
    (1) Name, call sign and category of station experiencing the 
interference;
    (2) Date and time of occurrence;
    (3) Geographical location at time of occurrence;
    (4) Frequency interfered with;
    (5) Nature of interference; and
    (6) Other particulars.



Sec.  87.481  Unattended operation of domestic radiobeacon stations.

    (a) Radiobeacons may be licensed for unattended operation. An 
applicant must comply with the following:
    (1) The transmitter is crystal controlled and specifically designed 
for radiobeacon service and capable of transmitting by self-actuating 
means;
    (2) The emissions of the transmitter must be continuously monitored 
by a licensed operator, or by a direct positive automatic monitor, 
supplemented by aural monitoring at suitable intervals;
    (3) If as a result of aural monitoring it is determined that a 
deviation from the terms of the station license has occurred, the 
transmitters must be disabled immediately by a properly authorized 
person. If automatic monitoring is used, the monitor must insure that 
the operation of the transmitter meets the license terms or is disabled;
    (4) A properly authorized person must be able to reach the 
transmitter and disable it in a reasonable amount of time, so as not to 
adversely affect life or property in the air;
    (5) The equipment must be inspected at least every 180 days. Results 
of inspections must be kept in the station maintenance records;

Sec.  87.483  Audio visual warning systems.

    An audio visual warning system (AVWS) is a radar-based obstacle 
avoidance system. AVWS activates obstruction lighting and transmits VHF 
audible warnings to alert pilots of potential collisions with land-based 
obstructions. The AVWS operations are limited to locations where natural 
and man-made obstructions exist. The continuously operating radar 
calculates the location, direction and groundspeed of nearby aircraft 
that enter one of two warning zones reasonably established by the 
licensee. As aircraft enter the first warning zone, the AVWS activates 
obstruction lighting. If the aircraft continues toward the obstacle and 
enters the second warning zone, the VHF

[[Page 228]]

radio transmits an audible warning describing the obstacle.
    (a) Radiodetermination (radar) frequencies. Frequencies authorized 
under Sec.  87.475(b)(8) of this chapter are available for use by an 
AVWS. The frequency coordination requirements in Sec.  87.475(a) of this 
chapter apply.
    (b) VHF audible warning frequencies. Frequencies authorized under 
Sec.  87.187(j), Sec.  87.217(a), Sec.  87.241(b), and Sec.  87.323(b) 
(excluding 121.950 MHz) of this chapter are available for use by an 
AVWS. Multiple frequencies may be authorized for an individual station, 
depending on need and the use of frequencies assigned in the vicinity of 
a proposed AVWS facility. Use of these frequencies is subject to the 
following limitations:
    (1) The output power shall not exceed -3 dBm watts for each 
frequency authorized.
    (2) The antenna used in transmitting the audible warnings must be 
omnidirectional with a maximum gain equal to or lower than a half-wave 
centerfed dipole above 30 degrees elevation, and a maximum gain of + 5 
dBi from horizontal up to 30 degrees elevation.
    (3) The audible warning shall not exceed two seconds in duration. No 
more than six audible warnings may be transmitted in a single transmit 
cycle, which shall not exceed 12 seconds in duration. An interval of at 
least twenty seconds must occur between transmit cycles.

Subpart R [Reserved]



            Subpart S_Automatic Weather Stations (AWOS/ASOS)



Sec.  87.525  Scope of service.

    Automatic weather observation stations (AWOS) and automatic surface 
observation stations (ASOS) must provide up-to-date weather information 
including the time of the latest weather sequence, altimeter setting, 
wind speed and direction, dew point, temperature, visibility and other 
pertinent data needed at airports having neither a full-time control 
tower nor a full-time FAA Flight Service Station. When a licensee has 
entered into an agreement with the FAA, an AWOS or an ASOS may also 
operate as an automatic terminal information station (ATIS) during the 
control tower's operating hours.

[64 FR 27476, May 20, 1999]



Sec.  87.527  Supplemental eligibility.

    (a) Licenses will be granted only upon FAA approval.
    (b) Eligibility for an AWOS, an ASOS, or an ATIS is limited to the 
owner or operator of an airport or to a person who has entered into a 
written agreement with the owner or operator for exclusive rights to 
operate and maintain the station. Where applicable a copy of the 
agreement between the applicant and owner or operator of the airport 
must be submitted with an application.
    (c) Only one AWOS, ASOS, or ATIS will be licensed at an airport.

[53 FR 28940, Aug. 1, 1988, as amended at 64 FR 27476, May 20, 1999]



Sec.  87.529  Frequencies.

    Prior to submitting an application, each applicant must notify the 
applicable FAA Regional Frequency Management Office. Each application 
must be accompanied by a statement showing the name of the FAA Regional 
Office and date notified. The Commission will assign the frequency. 
Normally, frequencies available for air traffic control operations set 
forth in subpart E will be assigned to an AWOS, ASOS, or to an ATIS. 
When a licensee has entered into an agreement with the FAA to operate 
the same station as both an AWOS and as an ATIS, or as an ASOS and an 
ATIS, the same frequency will be used in both modes of operation.

Sec.  90.15  Scope.

    The Public Safety Radio Pool covers the licensing of the radio 
communications of governmental entities and the following category of 
activities: Medical services, rescue organizations, veterinarians, 
persons with disabilities, disaster relief organizations, school buses, 
beach patrols, establishments in isolated places, communications standby 
facilities, and emergency repair of public communications facilities. 
Entities not meeting these eligibility criteria may also be licensed in 
the Public Safety Radio Pool solely to provide service to eligibles on 
one-way paging-only frequencies below 800 MHz, i.e., those frequencies 
with the assignment limitations appearing at Sec.  90.20(d)(13) or 
(d)(60). Private carrier systems licensed on other channels prior to 
June 1, 1990, may continue to provide radio communications service to 
eligibles. Rules as to eligibility for licensing, frequencies available, 
permissible communications and classes and number of stations, and any 
special requirements are set forth in the following sections.



Sec.  90.16  Public Safety National Plan.

    The Commission has established a National Plan which specifies 
special policies and procedures governing the Public Safety Pool 
(formally Public Safety Radio Services and the Special Emergency Radio 
Service). The National Plan is contained in the Report and Order in 
General Docket No. 87-112. The principal spectrum resource for the 
National Plan is the 806-809 MHz and the 851-854 MHz bands at locations 
farther then 110 km (68.4 miles) from the U.S./Mexico border and 140 km 
(87 miles) from the U.S./Canadian border (``border regions''). In the 
border regions, the principal spectrum for the National Plan may be 
different. The National plan establishes planning regions covering all 
parts of the United States, Puerto Rico, and the U.S. Virgin Islands. No 
assignments will be made in the spectrum designated for the National 
Plan until a regional plan for the area has been accepted by the 
Commission.

Areas. (1) We define service areas in the marine VHF (156-162 MHz) band 
by forty-two geographic areas called VHF Public Coast

[[Page 270]]

Service Areas (VPCSAs). See Sec.  80.371(c)(1)(ii) of this chapter 
(Public correspondence frequencies). VPCSAs are based on, and composed 
of one or more of, the U.S. Department of Commerce's 172 Economic Areas 
(EAs). See 60 Fed Reg. 13114 (Mar. 10, 1995). Maps of the EAs and VPCSAs 
are available for inspection through the Federal Communications 
Commission's Reference Information Center. These maps and data are also 
available on the FCC website at https://www.fcc.gov/oet/info/maps/
areas/. We number public correspondence channels in the maritime VHF 
(156-162 MHz) band as channels 24 to 28 and channels 84 to 88. Each 
channel number represents a channel pair. See Sec.  80.371(c) of this 
chapter.
    (2) In VHF Public Coast Service Areas (VPCSAs) 10-42, the duplex 
channel pair 157.250 MHz/161.850 MHz (VHF Maritime Channel 25) is 
allocated for public safety use by entities eligible for licensing under 
paragraph (a) of this section, and is designated primarily for the 
purpose of interoperability communications. See 47 CFR 80.371(c)(1)(ii) 
for the definitions of VPCSAs.
    (i) The channel pair 157.250 MHz/161.850 MHz was formerly allocated 
and assigned (under Sec.  80.371(c) (1997) of this chapter) as a public 
correspondence working channel in the maritime VHF 156-162 MHz band, and 
was also shared (under former Sec.  90.283 (1997) of this chapter) with 
private land mobile stations, including grandfathered public safety 
licensees. Thus, there are grandfathered licensees nationwide (maritime 
and private land mobile radio stations, including by rule waiver) 
operating on this channel both inside and outside of VPCSAs 10-42.
    (ii) The channel pairs 157.225 MHz/161.825 MHz and 157.275 MHz/
161.875 MHz were formerly allocated and assigned under this section as 
public safety interoperability channels but were reallocated for 
assignment as VHF public coast station channels under Sec.  80.371(c) of 
this chapter. Public safety operations licensed on these channels as of 
March 2, 2009 or licensed pursuant to an application filed prior to 
September 19, 2008, may remain authorized to operate on the channels on 
a primary basis until March 2, 2024.
    (3) All applicants and licensees under this paragraph must comply 
with the relevant technical sections under this part unless otherwise 
stated in this paragraph (g) of this section using the following 
standards and procedures:
    (i) Provide evidence of frequency coordination in accordance with 
Sec.  90.175. Public safety coordinators except the Special Emergency 
Coordinator are certified to coordinate applications for the channel 
pair 157.250 MHz/161.850 MHz (i.e., letter symbol PX under paragraph 
(c)(2) of this section).
    (ii) Station power, as measured at the output terminals of the 
transmitter, must not exceed 50 Watts for base stations and 20 Watts for 
mobile stations, except in accordance with the provisions of paragraph 
(g)(3)(vi) of this section. Antenna height (HAAT) must not exceed 122 
meters (400 feet) for base stations and 4.5 meters (15 feet) for mobile 
stations, except in accordance with paragraph (g)(3)(vi) of this 
section. Antenna height (HAAT) must not exceed 122 meters (400 feet) for 
base stations and 4.5 meters (15 feet) for mobile stations, except in 
accordance with paragraph (g)(3)(vi) of this section. Such base and 
mobile channels shall not be operated on board aircraft in flight.
    (iii) Frequency protection must be provided to other stations in 
accordance with the following guidelines for each channel and for each 
area and adjacent area:
    (A) Protect coast stations licensed prior to July 6, 1998, by the 
required separations shown in Table C below.
    (B) Protect stations described in paragraph (g)(2)(i) of this 
section, by frequency coordination in accordance Sec.  90.175 of this 
part.
    (C) Protect public safety stations granted under paragraph (g) of 
this section by frequency coordination in accordance with Sec.  90.175 
of this part.
    (D) Where the Public safety designated channel is not a Public 
safety designated channel in an adjacent VPCSA: Applicants shall 
engineer base stations such that the maximum signal strength at the 
boundary of the adjacent VPCSA does not exceed 5dB[micro]V/m.
    (iv) The following table, along with the antenna height (HAAT) and 
power (ERP), must be used to determine the

[[Page 271]]

minimum separation required between proposed base stations and co-
channel public coast stations licensed prior to July 6, 1998 under part 
80 of this chapter. Applicants whose exact ERP or HAAT are not reflected 
in the table must use the next highest figure shown.

    (v) In the event of interference, the Commission may require, 
without a hearing, licensees of base stations authorized under this 
section that are located within 241 kilometers (150 miles) of a co-
channel public coast, I/LT, or grandfathered public safety station 
licensed prior to July 6, 1998, or an international border, to reduce 
power, decrease antenna height, and/or install directional antennas.
    Mobile stations must be operated only within radio range of their 
associated base station.
    (vi) Applicants seeking to be licensed for stations exceeding the 
power/antenna height limits of the table in paragraph (g)(3)(iv) of this 
section must request a waiver of that paragraph and must submit with 
their application an interference analysis, based upon an appropriate, 
generally-accepted terrain-based propagation model, that shows that co-
channel protected entities, described in paragraph (g)(3)(iii) of this 
section, would receive the same or greater interference protection than 
the relevant criteria outlined in paragraph (g)(3)(iii) of this section.
    (h) Spectrum leasing arrangements. Notwithstanding any other 
provisions of this section to the contrary, licensees in the Public 
Safety Radio Services (see part 90, subpart B) may enter into spectrum 
leasing arrangements (see part 1, subpart X of this chapter) with 
entities providing communications in support of public safety 
operations.
    (i) Nationwide interoperability channels. The nationwide 
interoperability and mutual aid channels are listed below for the VHF, 
(including 220-222 MHz), UHF, 700 MHz and 800 MHz bands. (See Sec. Sec.  
90.20(d)(80), 90.531(b)(1), 90.617(a)(1) and 90.720). Any Part 90 public 
safety eligible entity holding a Part 90 license may operate hand-held 
and vehicular mobile units on these channels without needing a separate 
authorization. Base stations or control stations operating on these 
channels must be licensed separately: Encryption may not be used on any 
of the interoperability or mutual aid calling channels.

Sec.  90.22  Paging operations.

    Unless specified elsewhere in this part, paging operations may be 
authorized in the Public Safety Pool on any frequency except those 
assigned under the provisions of Sec.  90.20(d)(78). Paging operations 
on frequencies subject to Sec.  90.20(d)(78) authorized before August 
17, 1974, may be continued only if they do not cause harmful 
interference to regular operations on the same frequencies. Such paging 
operations may be renewed indefinitely on a secondary basis to regular 
operations, except within 125 km (75 mi) of the following urbanized 
areas:

Census of Population, 1960, vol. 1, table 23, page 1-50, only by persons 
rendering a central station commercial protection service within the 
service area of the radio station using the frequency and may be used 
only for communications pertaining to safety of life and property, and 
for maintenance or testing of the protection facilities. Central station 
commercial protection service is defined as an electrical protection and 
supervisory service rendered to the public from and by a central station 
accepted and certified by one or more of the recognized rating agencies, 
or the Underwriters Laboratories' (UL), or Factory Mutual System. Other 
stations in the Industrial/Business Pool may be licensed on this 
frequency without the central station alarm frequency coordinator's 
concurrence only when all base, mobile relay and control stations are 
located at least 120 km (75 miles) from the city center or centers of 
the specified urban areas of 200,000 or more population. With respect to 
combination urbanized areas containing more than one city, 120 km (75 
mile) separation shall be maintained from each city center which is 
included in the urbanized area. The locations of centers of cities are 
determined from appendix, page 226, of the U.S. Commerce publication 
``Air Line Distance Between Cities in the United States.''
    (64) Persons who render a central station commercial protection 
service are authorized to operate fixed stations on this frequency for 
the transmission of tone or impulse signals on a co-primary basis to

operations in the 896-901/935-940 MHz band.
    (72) Assignment of frequencies above 928 MHz for operational-fixed 
stations is governed by part 101 of this chapter.
    (73) Frequencies in this band are available only for one-way paging 
operations in accordance with Sec.  90.494.
    (74) Available only on a shared basis with stations in other 
services, and subject to no protection from interference due to the 
operation of industrial, scientific, or medical (ISM) devices. In the 
band 2483.5-2500 MHz, no applications for new stations or modification 
to existing stations to increase the number of transmitters will be 
accepted. Existing licensees as of July 25, 1985, and licensees whose 
initial applications were filed on or before July 25, 1985, are 
grandfathered and their operations are on a co-primary basis with the 
mobile-satellite and radiodetermination-satellite services, and in the 
segment 2495-2500 MHz, their operations are also on a co-primary basis 
with part 27 fixed and mobile except aeronautical mobile service 
operations.

electric utility that generates, transmits, or distributes electrical 
energy for use by the general public or by the members of a cooperative 
organization may operate PLC systems and shall supply to a Federal 
Communications Commission/National Telecommunications and Information 
Administration recognized industry-operated entity, information on all 
existing, changes to existing, and proposed systems for inclusion in a 
data base. Such information shall include the frequency, power, location 
of transmitter(s), location of receivers and other technical and 
operational parameters, which would characterize the system's potential 
both to interfere with authorized radio users, and to receive harmful 
interference from these users. In an agreed upon format, the industry-
operated entity shall inform the FCC and the NTIA of these system 
characteristics prior to implementation of any proposed PLC system and 
shall provide monthly or periodic lists with supplements of PLC systems. 
The FCC and NTIA will supply appropriate application and licensing 
information to the notification activity regarding authorized radio 
stations operating in the band. PLC systems in this band operate on a 
non-interference basis to radio systems assigned frequencies by the NTIA 
or licensed by the FCC and are not protected from interference due to 
these radio operations.

licensee as a base station or as a fixed station at unspecified or 
temporary locations for indeterminate periods, such transmitters may be 
considered to comprise a single station intended to be operated at 
temporary locations.
    (2) The application must specify the general geographic area within 
which the operation will be confined. The area may be specified as a 
city, a county or counties, a state or states or other definable 
geographic area such as a specified radius around a particular city or 
known geographic site.
    (3) Applications for operation at temporary locations exceeding 180 
days must be accompanied by evidence of frequency coordination, except 
that applications for operation at temporary locations exceeding 180 
days by applicants using 220-222 MHz spectrum for geophysical telemetry 
operations need not be accompanied by evidence of frequency 
coordination.
    (b) When any unit or units of a base station or fixed station which 
are authorized for operation at temporary locations actually remain or 
are intended to remain at the same location for more than 1 year, an 
application for a separate authorization specifying the fixed location 
shall be made as soon as possible, but not later than 30 days after the 
expiration of the 1-year period.
    (c) The provisions of this section do not apply to the 4940-4990 MHz 
band.

Sec.  90.149  License term.

    (a) Except as provided in subpart R of this part, licenses for 
stations authorized under this part will be issued for a term not to 
exceed ten (10) years from the date of the original issuance or renewal.
    (b) Non-exclusive geographic area licenses for DSRCS Roadside Units 
(RSUs) under subpart M of this part in the 5895-5925 MHz band will be 
issued for a term not to exceed ten years from the date of original 
issuance or renewal. The registration dates of individual RSUs (see 
Sec.  90.375) will not change the overall renewal period of the single 
license.

Sec.  90.155  Time in which station must be placed in operation.

    (a) All stations authorized under this part, except as provided in 
Sec. Sec.  90.528, 90.529, 90.629, 90.631(f), 90.665, and 90.685 must be 
placed in operation within twelve (12) months from the date of grant or 
the authorization cancels

[[Page 318]]

automatically and must be returned to the Commission.
    (b) A local government entity in the Public Safety Pool, applying 
for any frequency in this part, may also seek extended implementation 
authorization pursuant to Sec.  90.629.
    (c) For purposes of this section, a base station is not considered 
to be placed in operation unless at least one associated mobile station 
is also placed in operation. See also Sec. Sec.  90.633(d) and 
90.631(f).
    (d) Multilateration LMS EA-licensees, authorized in accordance with 
Sec.  90.353, must construct and place in operation a sufficient number 
of base stations that utilize multilateration technology (see paragraph 
(e) of this section) to provide multilateration location service to one-
third of the EA's population within five years of initial license grant, 
and two-thirds of the population within ten years. Licensees may, in the 
alternative, provide substantial service to their licensed area within 
the appropriate five- and ten-year benchmarks. In demonstrating 
compliance with the construction and coverage requirements, the 
Commission will allow licensees to individually determine an appropriate 
field strength for reliable service, taking into account the 
technologies employed in their system design and other relevant 
technical factors. At the five- and ten-year benchmarks, licensees will 
be required to file a map and FCC Form 601 showing compliance with the 
coverage requirements (see Sec.  1.946 of this chapter).
    (e) A multilateration LMS station will be considered constructed and 
placed in operation if it is built in accordance with its authorized 
parameters and is regularly interacting with one or more other stations 
to provide location service, using multilateration technology, to one or 
more mobile units. Specifically, LMS multilateration stations will only 
be considered constructed and placed in operation if they are part of a 
system that can interrogate a mobile, receive the response at 3 or more 
sites, compute the location from the time of arrival of the responses 
and transmit the location either back to the mobile or to a subscriber's 
fixed site.
    (f) For purposes of this section, a station licensed to provide 
commercial mobile radio service is not considered to have commenced 
service unless it provides service to at least one unaffiliated party.
    (g) Application for extension of time to commence service may be 
made on FCC Form 601. Extensions of time must be filed prior to the 
expiration of the construction period. Extensions will be granted only 
if the licensee shows that the failure to commence service is due to 
causes beyond its control. No extensions will be granted for delays 
caused by lack of financing, lack of site availability, for the 
assignment or transfer of control of an authorization, or for failure to 
timely order equipment. If the licensee orders equipment within 90 days 
of the license grant, a presumption of due diligence is created.
    (h) An application for modification of an authorization (under 
construction) at the existing location does not extend the initial 
construction period. If additional time to commence service is required, 
a request for such additional time must be submitted on FCC Form 601, 
either separately or in conjunction with the submission of the FCC Form 
601 requesting modification.
    (i) DSRCS Roadside Units (RSUs) under subpart M of this part in the 
5895-5925 MHz band must be placed in operation within 12 months from the 
effective date of registration (see Sec.  90.375) or the authority to 
operate the RSUs cancels automatically (see Sec.  1.955 of this 
chapter). Such registration date(s) do not change the overall renewal 
period of the single license. Licensees must notify the Commission in 
accordance with Sec.  1.946 of this chapter when registered units are 
placed in operation within their construction period.

  Special Rules Governing Facilities Used To Provide Commercial Mobile 
                             Radio Services

    Source: 59 FR 59959, Nov. 21, 1994; 63 FR 68964, Dec. 14, 1998, 
unless otherwise noted.

    Note: The following rules (Sec. Sec.  90.165 through 90.169) govern 
applications, licensing, and operation of radio facilities in the 220-
222 MHz (subpart T), Business Radio (subpart D), 929-930 MHz Paging 
(subpart P), and Specialized Mobile Radio (subpart S) services that are 
used to provide commercial mobile radio services (see Sec. Sec.  20.3 
and 20.9 of this chapter). Compliance with the rules relating to 
applications and licensing of facilities on paging-only channels in the 
Business Radio Service (see Sec.  90.75(c)(10)) and 929-930 MHz paging 
channels (see Sec.  90.494(a),(b)) is not required prior to August 10, 
1996. Compliance with Sec.  90.168 is also not required prior to August 
10, 1996 for reclassified commercial mobile radio service providers who 
are to be regulated as private carriers until August 10, 1996 as 
provided in the Second Report and Order in GN Docket No. 93-252, 9 FCC 
Rcd 2348 (1994), paras. 280-284. The licensing and operation of radio 
facilities in the 220-222 MHz (subpart T), Business Radio (subpart D), 
929-930 MHz Paging (subpart P), and Specialized Mobile Radio (subpart S) 
services that are used to provide commercial mobile radio services are 
also subject to rules elsewhere in this part that apply generally to 
Private Land Mobile Radio Services. In the case of any conflict between 
rules set forth in Sec. Sec.  90.165 through 90.169 and other rules in 
this part, Sec. Sec.  90.165 through 90.169 apply. 14-23. New Sec. Sec.  
90.165 through 90.169 are added to subpart G to read as follows:



Sec.  90.165  Procedures for mutually exclusive applications.

    Mutually exclusive commercial mobile radio service applications are 
processed in accordance with part 1 of this chapter and with the rules 
in this section, except for mutually exclusive applications for licenses 
in the 220-222 MHz service and the 929-930 MHz Paging service, which are 
processed in accordance with the rules in subpart P and subpart T of 
this part.
    Two or more pending applications are mutually exclusive if the grant 
of one application would effectively preclude the grant of one or more 
of the others under Commission rules governing the services involved.
    (a) Separate applications. Any applicant that files an application 
knowing that it will be mutually exclusive with one or more applications 
should not include in the mutually exclusive application a request for 
other channels or facilities that would not, by themselves, render the 
application mutually exclusive with those other applications. Instead, 
the request for such other channels or facilities should be filed in a 
separate application.
    (b) Filing groups. Pending mutually exclusive applications are 
processed in filing groups. Mutually exclusive applications in a filing 
group are given concurrent consideration. The Commission may dismiss as 
defective (pursuant to Sec.  1.934 of this chapter) any mutually 
exclusive application(s) whose filing date is outside of the date range 
for inclusion in the filing group. The types of filing groups used in 
day-to-day application processing are specified in paragraph (c)(3) of 
this section. A filing group is one of the following types:
    (1) Same-day filing group. A same-day filing group comprises all 
mutually exclusive applications whose filing date is the same day, which 
is normally the filing date of the first-filed applications(s).

[[Page 321]]

    (2) Thirty-day notice and cut-off filing group. A 30-day notice and 
cut-off filing group comprises mutually exclusive applications whose 
filing date is no later than thirty (30) days after the date of the 
Public Notice listing the first-filed application(s) (according to the 
filing dates) as acceptable for filing.
    (3) Window filing group. A window filing group comprises mutually 
exclusive applications whose filing date is within an announced filing 
window. An announced filing window is a period of time between and 
including two specific dates, which are the first and last dates on 
which applications (or amendments) for a particular purpose may be 
accepted for filing. In the case of a one-day filing window, the two 
dates are the same. The dates are made known to the public in advance.
    (c) Procedures. Generally, the Commission may grant one application 
in a filing group of mutually exclusive applications and dismiss the 
other application(s) in the filing group that are excluded by the grant, 
pursuant to Sec.  1.935 of this chapter.
    (1) Selection methods. In selecting the application to grant, the 
Commission may use competitive bidding, random selection, or comparative 
hearings, depending on the type of applications involved.
    (2) Dismissal of applications. The Commission may dismiss any 
application in a filing group that is defective or otherwise subject to 
dismissal under Sec.  1.934 of this chapter, either before or after 
employing selection procedures.
    (3) Type of filing group used. Except as otherwise provided in this 
part, the type of filing group used in processing of two or more 
mutually exclusive applications depends on the purpose(s) of the 
applications.
    (i) If any mutually exclusive application filed on the earliest 
filing date is an application for modification and none of the mutually 
exclusive applications is a timely-filed application for renewal, a 
same-day filing group is used.
    (ii) If any mutually exclusive application filed on the earliest 
filing date is an application for modification, a same-day filing group 
is used.
    (4) Disposition. If there is only one application in any type of 
filing group, the Commission may grant that application and dismiss 
without prejudice any mutually exclusive applications not in the filing 
group. If there is more than one mutually exclusive application in a 
filing group, the Commission disposes of these applications as follows:
    (i) Applications in a 30-day notice and cut-off filing group.
    (A) If all of the mutually exclusive applications in a 30-day notice 
and cut-off filing group are applications for initial authorization, the 
Commission administers competitive bidding procedures in accordance with 
subpart Q of part 1 of this chapter. After such procedures, the 
application of the successful bidder may be granted and the other 
applications may be dismissed without prejudice.
    (B) If any of the mutually exclusive applications in a 30-day notice 
and cut-off filing group is an application for modification or an 
application for facilities, the Commission may attempt to resolve the 
mutual exclusivity by facilitating a settlement between the applicants. 
If a settlement is not reached within a reasonable time, the Commission 
may designate all applications in the filing group for comparative 
consideration in a hearing. In this event, the result of the hearing 
disposes all of the applications in the filing group.
    (ii) Applications in a same-day filing group. If there are two or 
more mutually exclusive applications in a same-day filing group, the 
Commission may attempt to resolve the mutual exclusivity by facilitating 
a settlement between the applicants. If a settlement is not reached 
within a reasonable time, the Commission may designate all applications 
in the filing group for comparative consideration in a hearing. In this 
event, the result of the hearing disposes all of the applications in the 
filing group.
    (iii) Applications in a window filing group. Applications in a 
window filing group are processed in accordance with the procedures for 
a 30-day notice and cut-off filing group in paragraph (c)(4)(ii) of this 
section.

[[Page 322]]

    (d) Terminology. For the purposes of this section, terms have the 
following meanings:
    (1) The ``filing date'' of an application is the date on which that 
application was received in a condition acceptable for filing or the 
date on which the most recently filed major amendment to that 
application was received, whichever is later, excluding major amendments 
in the following circumstances:
    (i) The major amendment reflects only a change in ownership or 
control found by the Commission to be in the public interest;
    (ii) The major amendment as received is defective or otherwise found 
unacceptable for filing; or
    (iii) The application being amended has been designated for hearing 
and the Commission or the presiding officer accepts the major amendment.
    (2) An ``application for initial authorization'' is:
    (i) Any application requesting an authorization for a new system or 
station;
    (ii) Any application requesting authorization for an existing 
station to operate on an additional channel, unless the additional 
channel is for paired two-way radiotelephone operation, is in the same 
frequency range as the existing channel(s), and will be operationally 
integrated with the existing channel(s) such as by trunking; or
    (iii) any application requesting authorization for a new transmitter 
at a location more than 2 kilometers (1.2 miles) from any existing 
transmitters of the applicant licensee on the requested channel or 
channel block.

employment opportunity program, indicating specific practices to be 
followed in order to assure equal employment opportunity on the basis of 
sex, race, color, religion, or national origin in such aspects of 
employment practices as regards recruitment, selection, training, 
placement, promotion, pay, working conditions, demotion, layoff, and 
termination. Any licensee having sixteen (16) or more full-time 
employees that changes its existing equal employment opportunity program 
shall file with the Commission, no later than May 31st thereafter, a 
revised statement reflecting the change(s).

    Note: Commercial mobile radio service licensees having sixteen (16) 
or more full-time employees that do not have a current EEO statement on 
file with the Commission as of

[[Page 324]]

January 2, 1995, must file the statement required by this paragraph no 
later than May 31, 1995.

    (c) Report of complaints filed against licensees. Each licensee, 
regardless of how many employees it has, shall submit an annual report 
to the Commission no later than May 31st of each year indicating whether 
any complaints regarding violations by the licensee or equal employment 
provisions of Federal, State, Territorial, or local law have been filed 
before anybody having competent jurisdiction.
    (1) The report should state the parties involved, the date filing, 
the courts or agencies before which the matters have been heard, the 
appropriate file number (if any), and the respective disposition or 
current status of any such complaints.
    (2) Any licensee who has filed such information with the EEOC may 
file a notification of such filing with the Commission in lieu of a 
report.
    (d) Complaints of violations of Equal Employment Programs. 
Complaints alleging employment discrimination against a common carrier 
licensee are considered by the Commission in the following manner:
    (1) If a complaint raising an issue of discrimination is received 
against a licensee who is within the jurisdiction of the EEOC, it is 
submitted to that agency. The Commission maintains a liaison with that 
agency that keeps the Commission informed of the disposition of 
complaints filed against common carrier licensees.
    (2) Complaints alleging employment discrimination against a common 
carrier licensee who does not fall under the jurisdiction of the EEOC 
but is covered by appropriate enforceable State law, to which penalties 
apply, may be submitted by the Commission to the respective State 
agency.
    (3) Complaints alleging employment discrimination against a common 
carrier licensee who does not fall under the jurisdiction of the EEOC or 
an appropriate State law, are accorded appropriate treatment by the 
Commission.
    (4) The Commission will consult with the EEOC on all matters 
relating to the evaluation and determination of compliance by the common 
carrier licensees with the principles of equal employment as set forth 
herein.
    (5) Complaints indicating a general pattern of disregard of equal 
employment practices which are received against a licensee that is 
required to file an employment report to the Commission under Sec.  
1.815(a) of this chapter are investigated by the Commission.
    (e) Commission records. A copy of every annual employment report, 
equal employment opportunity program statement, reports on complaints 
regarding violation of equal employment provisions of Federal, State, 
Territorial, or local law, and copies of all exhibits, letters, and 
other documents filed as part thereof, all amendments thereto, all 
correspondence between the licensee and the Commission pertaining to the 
reports after they have been filed and all documents incorporated 
therein by reference, are open for public inspection at the offices of 
the Commission.
    (f) Licensee records. Each licensee required to file annual 
employment reports (pursuant to Sec.  1.815(a) of this chapter), equal 
employment opportunity program statements, and annual reports on 
complaints regarding violations of equal employment provisions of 
Federal, State, Territorial, or local law shall maintain for public 
inspection a file containing a copy of each such report and copies of 
all exhibits, letters, and other documents filed as part thereto, all 
correspondence between the licensee and the Commission pertaining to the 
reports after they have been filed and all documents incorporated 
therein by reference. The documents must be retained for a period of two 
(2) years.



Sec.  90.169  Construction prior to grant of application.

    Applicants may construct facilities prior to grant of their 
applications, subject to the provisions of this section, but must not 
operate such facilities until the Commission grants an authorization. If 
the conditions stated in this section are not met, applicants must not 
begin to construct facilities.
    (a) When applicants may begin construction. An applicant may begin 
construction of a facility thirty-five (35) days after the date of the 
Public Notice

[[Page 325]]

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



       Subpart H_Policies Governing the Assignment of Frequencies



Sec.  90.171  Scope.

    This subpart contains detailed information concerning the policies 
under which the Commission assigns frequencies for the use of licensees 
under this part, frequency coordination procedures, and procedures under 
which licensees may cooperatively share radio facilities.



Sec.  90.173  Policies governing the assignment of frequencies.

    (a) Except as indicated in paragraph (j) of this section, the 
frequencies which ordinarily may be assigned to stations in the services 
governed by this part are listed in subparts B, C and F of this part. 
Except as otherwise specifically provided in this part, frequencies 
assigned to land mobile stations are available on a shared basis only 
and will not be assigned for the exclusive use of any licensee.
    (b) All applicants and licensees shall cooperate in the selection 
and use of frequencies in order to reduce interference and make the most 
effective use of the authorized facilities. Licensees of stations 
suffering or causing harmful interference are expected to cooperate and 
resolve this problem by mutually satisfactory arrangements. If the 
licensees are unable to do so, the Commission may impose restrictions 
including specifying the transmitter power, antenna height, or area or 
hours of operation of the stations concerned. Further the use of any 
frequency at a given geographical location may be denied when, in the 
judgment of the Commission, its use in that location is not in the 
public interest; the use of any frequency may be restricted as to 
specified geographical areas, maximum power, or such other operating 
conditions, contained in this part or in the station authorization.
    (c) Frequencies assigned to Federal Government radio stations by the 
National Telecommunications and Information Administration may be 
authorized under the provisions set forth in Sec.  2.102(c) of this 
chapter.
    (d) The radio facilities authorized under this part are intended for 
use in connection with and as an adjunct to

[[Page 326]]

the primary governmental or business activities of the licensee.
    (e) Persons requesting authority to operate in the band 25-50 MHz 
should recognize that this band is shared with various services in other 
countries and that harmful interference may be caused by the propagation 
of signals in this band from distant stations. No protection from such 
harmful interference generally can be expected.
    (f) Applications for stations in the 150-174 MHz and 421-512 MHz 
bands for operation on frequencies 15 kHz or less removed from existing 
stations in the same geographic area will be granted based upon a 
recommendation from the applicable frequency coordinator as specified in 
Sec. Sec.  90.20(c)(2) and 90.35(b)(2).
    (g) In the states of Alaska and Hawaii, and in areas outside the 
continental limits of the United States and the adjacent waters, the 
frequencies above 150.8 MHz which are listed elsewhere in this part as 
available for assignment to base stations or mobile stations in the 
Industrial/Business Pool are also available for assignment to 
operational fixed stations in the Industrial/Business Pool on a 
secondary basis.
    (h) In the Public Safety Pool, base stations may be authorized to 
operate on a secondary basis on frequencies below 450 MHz which are 
available to mobile stations.
    (i) In the 450-470 MHz band, the frequencies are ordinarily assigned 
in pairs, with the mobile station transmit frequency 5 MHz above the 
paired base station transmit frequency. In the 470-512 MHz band, the 
frequencies are ordinarily assigned in pairs with the mobile station 
transmit frequency 3 MHz above the paired base station transmit 
frequency. In the Industrial/Business Pool, in the 150 MHz band, the 
frequencies subject to Sec.  90.35(c)(6) may be assigned in pairs with 
the separation between base and mobile frequencies being 5.26 MHz. A 
mobile station may be assigned the frequency which would normally be 
assigned to a base station for single-frequency operation. However, this 
single-frequency operation may be subject to interference that would not 
occur to a two-frequency system.
    (j) Frequencies other than those listed in subparts B and C of this 
part may be assigned in the 150-174 MHz, 421-430 MHz, 450-470 MHz, and 
470-512 MHz bands, provided the following conditions are met:
    (1) Such applications must be accompanied by a showing of frequency 
coordination in accordance with the requirements of Sec.  90.175;
    (2) The frequencies must not be available in any other rule part of 
this chapter; and
    (3) The authorized bandwidth of any system operating in accordance 
with this paragraph must not overlap spectrum available in other rule 
parts of this chapter unless that spectrum is also allocated in part 90.
    (k) This paragraph is only applicable to entities with Finder's 
Preference requests pending before the Commission as of July 29, 1998. 
Notwithstanding any other provisions of this part, any eligible person 
shall be given a dispositive preference for a channel assignment on an 
exclusive basis in the 220-222 MHz, 470-512 MHz, and 800/900 MHz (except 
on frequencies designated exclusively for SMR service) bands by 
submitting information that leads to the recovery of channels in these 
bands. Recovery of such channels must result from information provided 
regarding the failure of existing licensees to comply with the 
provisions of Sec.  90.155, Sec.  90.157, Sec.  90.629, Sec.  90.631 (e) 
or (f), or Sec.  90.633 (c) or (d).
    (l) In the 150-174 MHz band, except where otherwise specifically 
provided, authorizations for frequencies that were available prior to 
August 18, 1995 will be granted with channel bandwidths of 25 kHz or 
less. Authorizations for all other frequencies in this band will be 
granted with channel bandwidths of 12.5 kHz or less (i.e., in the Public 
Safety Pool, frequencies subject to Sec. Sec.  90.20 (d)(27) and 
(d)(44), and in the Industrial/Business Pool, frequencies subject to 
Sec. Sec.  90.35 (c)(30) and (c)(33)).
    (m) In the 421-512 MHz band, except where otherwise specifically 
provided, authorizations for frequencies that were available prior to 
August 18, 1995 will be granted with channel

[[Page 327]]

bandwidths of 25 kHz or less. New authorizations for frequencies 12.5 
kHz removed from these frequencies will be made for channel bandwidths 
of 12.5 kHz or less (i.e., in the Public Safety Pool, frequencies 
subject to Sec.  90.20(d)(27) and in the Industrial/Business Pool, 
frequencies subject to Sec.  90.35(c)(30)). Authorizations for 
frequencies 6.25 kHz removed from these frequencies will be granted with 
channel bandwidths of 6.25 kHz or less (i.e., in the Public Safety Pool, 
frequencies subject to Sec.  90.20(d)(44), and in the Industrial/
Business Pool, frequencies subject to Sec.  90.35(c)(33)).
    (n) Any recovered channels in the 800 MHz SMR service will revert 
automatically to the holder of the EA license within which such channels 
are included. If there is no EA licensee for recovered channels, such 
channels will be retained by the Commission for future licensing.

Sec.  90.175  Frequency coordinator requirements.

    Except for applications listed in paragraph (j) of this section, 
each application for a new frequency assignment, for a change in 
existing facilities as listed in Sec.  90.135(a), or for operation at 
temporary locations in accordance with Sec.  90.137 must include a 
showing of frequency coordination as set forth further.
    (a) Frequency coordinators may request, and applicants are required 
to provide, all appropriate technical information, system requirements, 
and justification for requested station parameters when such information 
is necessary to identify and recommend the most appropriate frequency. 
Additionally, applicants bear the burden of proceeding and the burden of 
proof in requesting the Commission to overturn a coordinator's 
recommendation.
    (b) For frequencies between 25 and 470 MHz. (1) A statement is 
required from the applicable frequency coordinator as specified in 
Sec. Sec.  90.20(c)(2) and 90.35(b) recommending the most appropriate 
frequency. In addition, for frequencies to which Sec.  90.35(c)(63) or 
(66) is applicable, the written concurrence of the Commission-certified 
frequency coordinator for frequencies designated for central station 
alarm operations must be obtained. In addition, for frequencies above 
150 MHz, if the interference contour of a proposed station would overlap 
the service contour of a station on a frequency formerly shared prior to 
radio service consolidation by licensees in the Manufacturers Radio 
Service, the Forest Products Radio Service, the Power Radio Service, the 
Petroleum Radio Service, the Motor Carrier Radio Service, the Railroad 
Radio Service, the Telephone Maintenance Radio Service or the Automobile 
Emergency Radio Service, the written concurrence of the coordinator for 
the industry-specific service, or the written concurrence of the 
licensee itself, must be obtained. Requests for concurrence must be 
responded to within 20 days of receipt of the request. The written 
request for concurrence shall advise the receiving party of the maximum 
20 day response period. The coordinator's recommendation may include 
comments on technical factors such as power, antenna height and gain, 
terrain and other factors which may serve to minimize potential 
interference. In addition:
    (2) On frequencies designated for coordination or concurrence by a 
specific frequency coordinator as specified in Sec. Sec.  90.20(c)(3) 
and 90.35(b), and on frequencies designated for concurrence as specified 
in Sec.  90.35(c)(63) or (66), the applicable frequency coordinator 
shall provide a written supporting statement in instances in which 
coordination or concurrence is denied. The supporting statement shall 
contain sufficient detail to permit discernment of the technical basis 
for the denial of concurrence. Concurrence may be denied only when a 
grant of the underlying application would have a demonstrable, material, 
adverse effect on safety.
    (3) In instances in which a frequency coordinator determines that an 
applicant's requested frequency or the most

[[Page 328]]

appropriate frequency is one designated for coordination or concurrence 
by a specific frequency coordinator as specified in Sec.  90.20(c)(3) or 
Sec.  90.35(b), that frequency coordinator may forward the application 
directly to the appropriate frequency coordinator. A frequency 
coordinator may only forward an application as specified above if 
consent is received from the applicant.
    (4) For any application for mobile repeater station operations on 
frequencies denoted by both Sec.  90.20(d)(90) and (92), or by both 
Sec.  90.35(c)(93) and (95) the frequency coordinator responsible for 
the application must determine and disclose to the applicant the call 
signs and the service areas of all active co-channel incumbent remote 
control and telemetry stations inside the applicant's proposed area of 
operation by adding a special condition to the application, except when 
the applicant has obtained written concurrence from an affected 
incumbent licensee, or when the applicant and the incumbent licensee are 
the same entity.
    (c) For frequencies above 800 MHz: When frequencies are shared by 
more than one service, concurrence must be obtained from the other 
applicable certified coordinators.
    (d) For frequencies in the 450-470 MHz band: When used for secondary 
fixed operations, frequencies shall be assigned and coordinated pursuant 
to Sec.  90.261.
    (e) For frequencies between 470-512 MHz, 769-775/799-805 MHz, 806-
824/851-869 MHz and 896-901/935-940 MHz: A recommendation of the 
specific frequencies that are available for assignment in accordance 
with the loading standards and mileage separations applicable to the 
specific radio service, frequency pool, or category of user involved is 
required from an applicable frequency coordinator. In addition, a 
frequency coordinator must perform the contour overlap analysis detailed 
in Sec.  90.621(d) when coordinating applications for channels in the 
809-817 MHz/854-862 MHz band segment once interstitial 12.5 kHz 
bandwidth channels become available for licensing in a National Public 
Safety Planning Advisory Committee region.
    (f) For frequencies in the 929-930 MHz band listed in paragraph (b) 
of Sec.  90.494: A statement is required from the coordinator 
recommending the most appropriate frequency.
    (g) For frequencies between 1427-1432 MHz and 4940-4990 MHz: A 
statement is required as follows.
    (1) For frequencies between 1427-1432 MHz: A statement is required 
from the coordinator recommending the most appropriate frequency, 
operating power and area of operation in accordance with the 
requirements of Sec.  90.259(b).
    (2) For frequencies between 4940-4990 MHz: A statement is required 
from the nationwide band manager recommending the most appropriate 
channel(s), bandwidth, operating power, and any other technical 
parameter which promotes robust and efficient use of the band while 
minimizing interference based on the standard for harmful interference 
specified in Sec.  90.1211(a).
    (3) Compliance date. Paragraph (g)(2) of this section may contain 
information collection and/or recordkeeping requirements. Compliance 
with paragraph (g)(2) will not be required until this paragraph (g)(3) 
is removed or contains a compliance date, which will not occur until the 
date specified in a final rule published by the FCC announcing that the 
Office of Management and Budget has completed review of any information 
collection requirements associated with paragraph (g)(2) of this section 
or that they have determined such review is not required, which date 
shall be no earlier than February 28, 2024.
    (h) Any recommendation submitted in accordance with paragraphs (a), 
(c), (d), or (e) of this section is advisory in character and is not an 
assurance that the Commission will grant a license for operation on that 
frequency. Therefore, applicants are strongly advised not to purchase 
radio equipment operating on specific frequencies until a valid 
authorization has been obtained from the Commission.
    (i) Applications for facilities near the Canadian border north of 
line A or east of line C in Alaska may require coordination with the 
Canadian government. See Sec.  1.928 of this chapter.

Sec.  90.179  Shared use of radio stations.

    Licensees of radio stations authorized under this rule part may 
share the use of their facilities. A station is shared when persons not 
licensed for the station control the station for their own purposes 
pursuant to the licensee's authorization. Shared use of a radio station 
may be either on a non-profit cost shared basis or on a for-profit 
private carrier basis. Shared use of an authorized station is subject to 
the following conditions and limitations:
    (a) Persons may share a radio station only on frequencies for which 
they would be eligible for a separate authorization.
    (b) The licensee of the shared radio station is responsible for 
assuring that the authorized facility is used only by persons and only 
for purposes consistent with the requirements of this rule part.
    (c) Participants in the sharing arrangement may obtain a license for 
their own mobile units (including control points and/or control stations 
for control of the shared facility), or they may use mobile stations, 
and control stations or control points authorized to the licensee.
    (d) If the licensee shares the land station on a non-profit, cost 
shared basis to the licensee, this shared use must be pursuant to a 
written agreement between the licensee and each participant which sets 
out (1) the method of operation, (2) the components of the system which 
are covered by the sharing arrangements, (3) the method by which costs 
are to be apportioned, and (4) acknowledgement that all shared 
transmitter use must be subject to the licensee's control. These 
agreements

[[Page 331]]

must be kept as part of the station records.
    (e) If the land station which is being shared is interconnected with 
the public switched telephone network, the provisions of Sec.  90.477 et 
seq. apply.
    (f) Above 800 MHz, shared use on a for-profit private carrier basis 
is permitted only by SMR, Private Carrier Paging, LMS, and DSRCS 
licensees. See subparts M, P, and S of this part.
    (g) Notwithstanding paragraph (a) of this section, licensees 
authorized to operate radio systems on Public Safety Pool frequencies 
designated in Sec.  90.20 may share their facilities with Federal 
Government entities on a non-profit, cost-shared basis. Such a sharing 
arrangement is subject to the provisions of paragraphs (b), (d), and (e) 
of this section, and Sec.  2.103(c) of this chapter concerning 
operations in the 758-769 MHz and 788-799 MHz bands. State governments

Sec.  90.187  Trunking in the bands between 150 and 512 MHz.

    (a) Applicants for centralized and decentralized trunked systems 
operating on frequencies between 150 and 512 MHz (except 220-222 MHz) 
must indicate on their applications (radio service and class of station 
code, instructions for FCC Form 601) that their system will be trunked. 
Licensees of stations that are not trunked may trunk their systems only 
after modifying their license (see Sec.  1.927 of this chapter).
    (b) Except as provided in paragraphs (c) and (d) of this section, 
trunked systems operating under this section must employ equipment that 
prevents transmission on a trunked frequency if a signal from another 
system is present on that frequency. The level of monitoring must be 
sufficient to avoid harmful interference to other systems.
    (c) The monitoring requirement in paragraph (b) of this section does 
not apply to trunked systems operating in the 470-512 MHz band that meet 
the loading requirements of Sec.  90.313 and have exclusive use of their 
frequencies in their service area.
    (d) The monitoring requirement in paragraph (b) of this section does 
not

[[Page 332]]

apply if the application is accompanied by written consent from all 
affected licensees.
    (1) Affected licensees for the purposes of this section are 
licensees (and previously filed pending applicants) meeting both a 
spectral and a contour overlap as defined:
    (i) Spectral overlap. Licensees (and filers of previously filed 
pending applications) with an assigned (or proposed) frequency having a 
spectral separation from a frequency of the proposed centralized trunked 
station that does not exceed these values:

----------------------------------------------------------------------------------------------------------------
                                                             Incumbent authorized bandwidth
           Proposed station            -------------------------------------------------------------------------
                                                 25 kHz                  12.5 kHz                6.25 kHz

25 kHz................................  15.0 kHz                 15.0 kHz                 15.0 kHz
12.5 kHz..............................  15.0 kHz                 7.5 kHz                  7.5 kHz
6.25 kHz..............................  15.0 kHz                 7.5 kHz                  5.0 kHz
----------------------------------------------------------------------------------------------------------------
The left column is the authorized bandwidth requested for the proposed trunked station. The second row is the
  authorized bandwidth of the incumbent. The other cells in the table show the frequency range above and below
  the frequency of the proposed centralized trunked station that must be considered.

    (ii) Contour overlap. (A) Licensees (and filers of previously filed 
pending applications) with a service contour (37 dBu for stations in the 
150-174 MHz band, and 39 dBu for stations in the 421-512 MHz band) that 
is overlapped by the proposed centralized trunked station's interference 
contour (19 dBu for stations in the 150-174 MHz band, and 21 dBu for 
stations in the 421-512 MHz band). Contour calculations are required for 
base station facilities. Contour calculations are required for 
associated mobile stations only in the 150-174 MHz band, with the 
associated base station's service contour used as both the mobile 
station's service contour and its interference contour.
    (B) The calculation of service and interference contours shall be 
performed using generally accepted engineering practices and standards, 
including appropriate derating factors, agreed to by a consensus of all 
certified frequency coordinators. Frequency coordinators shall make this 
information available to the Commission upon request.
    (C) For purposes of this section, the authorized operating area of a 
station or proposed station with no associated base station shall be 
used as both the station's service contour and its interference contour.
    (D) After January 1, 2013, licensees with an authorized bandwidth 
exceeding 12.5 kHz will not be deemed affected licensees, unless the 
licensee meets the efficiency standard set forth in Sec.  90.203(j)(3) 
or the licensee was granted a waiver of Sec.  90.209(b).
    (2) The written consent from an affected licensee shall state all 
terms agreed to by the parties and shall be signed by the parties. The 
written consent shall be maintained by the operator of the centralized 
trunked station and be made available to the Commission upon request. An 
application for a centralized trunked station shall include either a 
certification from the applicant that written consent has been obtained 
from all affected licensees, or a certification from the frequency 
coordinator that there are no affected licensees.
    (3) In addition, the service contour for proposed centralized 
trunked stations on Industrial/Business Pool frequencies shall not be 
overlapped by an incumbent licensee's interference contour. An 
application filed for Public Safety Pool frequencies, see Sec.  90.20, 
for a proposed centralized trunked station in which the service contour 
of the proposed station is overlapped by the interference contour of the 
incumbent station(s) is allowed, but the applicant must accept any 
resultant interference.
    (e) The exclusive service area of a station that has been authorized 
for centralized trunked operation will be protected from proposed 
centralized trunked, decentralized trunked or conventional operations in 
accordance with the standards of paragraph (d) of this section.
    (f) Trunking of systems licensed on paging-only channels or licensed 
in the Radiolocation Service (subpart F) is not permitted.

[[Page 333]]

    (g) Channel limits. (1) No more than 10 channels for new centralized 
trunked operation in the Industrial/Business Pool may be applied for at 
a single transmitter location or at locations with overlapping service 
contours as specified in paragraph (d) of this section. Subsequent 
applications for centralized trunked operation are limited to no more 
than an additional 10 channels, and must be accompanied by a 
certification, submitted to the certified frequency coordinator 
coordinating the application, that all of the applicant's existing 
channels authorized for centralized trunked operation at that location 
or at locations with overlapping service contours have been constructed 
and placed in operation. Certified frequency coordinators are authorized 
to require documentation in support of the applicant's certification 
that existing channels have been constructed and placed in operation.
    (2) Applicants for Public Safety Pool channels may request more than 
10 centralized trunked channels at a single location or at locations 
with overlapping service contours if accompanied by a showing of 
sufficient need. The requirement for such a showing may be satisfied by 
submission of loading studies demonstrating that requested channels in 
excess of 10 will be loaded with 50 mobiles per channel within a five 
year period commencing with the grant of the application.
    (h) If a licensee authorized for centralized trunked operation 
discontinues trunked operation for a period of 30 consecutive days, the 
licensee, within 7 days thereafter, shall file a conforming application 
for modification of license with the Commission.

will be submitted to the frequency coordinator accompanied by a 
technical analysis, based upon generally accepted engineering practices 
and standards, that demonstrates that the requested station parameters 
will not produce a signal strength in excess of 37 dBu at any point 
along the edge of the requested service area. The coordinator may then 
recommend any ERP appropriate to meet this condition.
    (3) An applicant for a station with a service area radius greater 
than 40 km (25 mi) must justify the requested service area radius, which 
will be authorized only in accordance with table 1, note 4. For base 
stations with service areas greater than 80 km, all operations 80 km or 
less from the base station will be on a primary basis and all operations 
outside of 80 km from the base station will be on a secondary basis and 
will be entitled to no protection from primary operations.

Sec.  90.209  Bandwidth limitations.

    (a) Each authorization issued to a station licensed under this part 
will show an emission designator representing the class of emission 
authorized. The designator will be prefixed by a specified necessary 
bandwidth. This number does not necessarily indicate the bandwidth 
occupied by the emission at any instant. In those cases where Sec.  
2.202 of this chapter does not provide a formula for the computation of 
necessary bandwidth, the occupied bandwidth, as defined in part 2 of 
this chapter, may be used in lieu of the necessary bandwidth.

[[Page 340]]

    (b) The maximum authorized single channel bandwidth of emission 
corresponding to the type of emission specified in Sec.  90.207 is as 
follows:
    (1) For A1A or A1B emissions, the maximum authorized bandwidth is 
0.25 kHz. The maximum authorized bandwidth for type A3E emission is 8 
kHz.
    (2) For operations below 25 MHz utilizing J3E emission, the 
bandwidth occupied by the emission shall not exceed 3000 Hz. The 
assigned frequency will be specified in the authorization. The 
authorized carrier frequency will be 1400 Hz lower in frequency than the 
assigned frequency. Only upper sideband emission may be used. In the 
case of regularly available double sideband radiotelephone channels, an 
assigned frequency for J3E emissions is available either 1600 Hz below 
or 1400 Hz above the double sideband radiotelephone assigned frequency.
    (3) For all other types of emissions, the maximum authorized 
bandwidth shall not be more than that normally authorized for voice 
operations.
    (4) Where a frequency is assigned exclusively to a single licensee, 
more than a single emission may be used within the authorized bandwidth. 
In such cases, the frequency stability requirements of Sec.  90.213 must 
be met for each emission.
    (5) Unless specified elsewhere, channel spacings and bandwidths that 
will be authorized in the following frequency bands are given in the 
following table.

Sec.  90.210  Emission masks.

    Except as indicated elsewhere in this part, transmitters used in the 
radio services governed by this part must comply with the emission masks 
outlined in this section. Unless otherwise stated, per paragraphs 
(d)(4), (e)(4), and (o) of this section, measurements of emission power 
can be expressed in either peak or average values provided that emission 
powers are expressed with the same parameters used to specify the 
unmodulated transmitter carrier power. For transmitters that do not 
produce a full power unmodulated carrier, reference to the unmodulated 
transmitter carrier power refers to the total power contained in the 
channel bandwidth. Unless indicated elsewhere in this part, the table in 
this section specifies the emission masks for equipment operating under 
this part.
    (a) Emission Mask A. For transmitters utilizing J3E emission, the 
carrier must be at least 40 dB below the peak envelope power and the 
power of emissions must be reduced below the output power (P in watts) 
of the transmitter as follows:
    (1) On any frequency removed from the assigned frequency by more 
than 50 percent, but not more than 150 percent of the authorized 
bandwidth: At least 25 dB.
    (2) On any frequency removed from the assigned frequency by more 
than 150 percent, but not more than 250 percent of the authorized 
bandwidth: At least 35 dB.
    (3) On any frequency removed from the assigned frequency by more 
than 250 percent of the authorized bandwidth: At least 43 + 10 log P dB.
    (b) Emission Mask B. For transmitters that are equipped with an 
audio low-pass filter, the power of any emission must be attenuated 
below the unmodulated carrier power (P) as follows:
    (1) On any frequency removed from the assigned frequency by more 
than 50 percent, but not more than 100 percent of the authorized 
bandwidth: At least 25 dB.

[[Page 342]]

    (2) On any frequency removed from the assigned frequency by more 
than 100 percent, but not more than 250 percent of the authorized 
bandwidth: At least 35 dB.
    (3) On any frequency removed from the assigned frequency by more 
than 250 percent of the authorized bandwidth: At least 43 + 10 log (P) 
dB.
    (c) Emission Mask C. For transmitters that are not equipped with an 
audio low-pass filter, the power of any emission must be attenuated 
below the unmodulated carrier output power (P) as follows:
    (1) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in kHz) of more 
than 5 kHz, but not more than 10 kHz: At least 83 log (fd/5) 
dB;
    (2) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in kHz) of more 
than 10 kHz, but not more than 250 percent of the authorized bandwidth: 
At least 29 log (fd\2\/11) dB or 50 dB, whichever is the 
lesser attenuation;
    (3) On any frequency removed from the center of the authorized 
bandwidth by more than 250 percent of the authorized bandwidth: At least 
43 + 10 log (P) dB.
    (4) In the 1427-1432 MHz band, licensees are encouraged to take all 
reasonable steps to ensure that unwanted emissions power does not exceed 
the following levels in the 1400-1427 MHz band:
    (i) For stations of point-to-point systems in the fixed service: -45 
dBW/27 MHz.
    (ii) For stations in the mobile service: -60 dBW/27 MHz.
    (d) Emission Mask D--12.5 kHz channel bandwidth equipment. For 
transmitters designed to operate with a 12.5 kHz channel bandwidth, any 
emission must be attenuated below the power (P) of the highest emission 
contained within the authorized bandwidth as follows:
    (1) On any frequency from the center of the authorized bandwidth 
f0 to 5.625 kHz removed from f0: Zero dB.
    (2) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in kHz) of more 
than 5.625 kHz but no more than 12.5 kHz: At least 7.27(fd-
2.88 kHz) dB.
    (3) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in kHz) of more 
than 12.5 kHz: At least 50 + 10 log (P) dB or 70 dB, whichever is the 
lesser attenuation.
    (4) The reference level for showing compliance with the emission 
mask shall be established using a resolution bandwidth sufficiently wide 
(usually two or three times the channel bandwidth) to capture the true 
peak emission of the equipment under test. In order to show compliance 
with the emission mask up to and including 50 kHz removed from the edge 
of the authorized bandwidth, adjust the resolution bandwidth to 100 Hz 
with the measuring instrument in a peak hold mode. A sufficient number 
of sweeps must be measured to insure that the emission profile is 
developed. If video filtering is used, its bandwidth must not be less 
than the instrument resolution bandwidth. For emissions beyond 50 kHz 
from the edge of the authorized bandwidth, see paragraph (o) of this 
section. If it can be shown that use of the above instrumentation 
settings do not accurately represent the true interference potential of 
the equipment under test, an alternate procedure may be used provided 
prior Commission approval is obtained.
    (e) Emission Mask E--6.25 kHz or less channel bandwidth equipment. 
For transmitters designed to operate with a 6.25 kHz or less bandwidth, 
any emission must be attenuated below the power (P) of the highest 
emission contained within the authorized bandwidth as follows:
    (1) On any frequency from the center of the authorized bandwidth 
f0 to 3.0 kHz removed from f0: Zero dB.
    (2) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in kHz) of more 
than 3.0 kHz but no more than 4.6 kHz: At least 30 + 
16.67(fd-3 kHz) or 55 + 10 log (P) or 65 dB, whichever is the 
lesser attenuation.
    (3) On any frequency removed from the center of the authorized 
bandwidth by more than 4.6 kHz: At least 55 + 10 log (P) or 65 dB, 
whichever is the lesser attenuation.

    (4) The reference level for showing compliance with the emission 
mask shall be established using a resolution bandwidth sufficiently wide 
(usually two or three times the channel bandwidth) to capture the true 
peak emission of the equipment under test. In order to show compliance 
with the emission mask up to and including 50 kHz removed from the edge 
of the authorized bandwidth, adjust the resolution bandwidth to 100 Hz 
with the measuring instrument in a peak hold mode. A sufficient number 
of sweeps must be measured to insure that the emission profile is 
developed. If video filtering is used, its bandwidth must not be less 
than the instrument resolution bandwidth. For emissions beyond 50 kHz 
from the edge of the authorized bandwidth, see paragraph (o) of this 
section. If it can be shown that use of the above instrumentation 
settings do not accurately represent the true interference potential of 
the equipment under test, an alternate procedure may be used provided 
prior Commission approval is obtained.

transmitters authorized under subpart M to provide forward or reverse 
links in a multilateration system in the subbands 904-909.75 MHz, 
921.75-927.25 MHz and 919.75-921.75 MHz, and which transmit an emission 
occupying more than 50 kHz bandwidth: in any 100 kHz band, the center 
frequency of which is removed from the center of authorized sub-band(s) 
by more than 50 percent of the authorized bandwidth, the power of 
emissions shall be attenuated below the transmitter output power, as 
specified by the following equation, but in no case less than 31 dB:

A = 16 + 0.4 (D-50) + 10 log B (attenuation greater than 66 dB is not

(fd in kHz): at least 116 log ((fd + 10)/6.1) dB 
or 50 + 10 log (P) dB or 70 dB, whichever is the lesser attenuation.

    (3) Other transmitters. For all other transmitters authorized under

contained within the licensee's sub-band in accordance with the 
following schedule:
    (i) On any frequency within the authorized bandwidth: Zero dB.
    (ii) On any frequency outside the licensee's sub-band edges: 55 + 10

45% of the authorized bandwidth (BW): 0 dB.
    (2) On any frequency removed from the assigned frequency between 45-
50% of the authorized bandwidth: 219 log (% of (BW)/45) dB.

of the authorized bandwidth: 40 dB.
    (7) The zero dB reference is measured relative to the highest 
average power of the fundamental emission measured across the designated 
channel bandwidth using a resolution bandwidth of at least one percent 
of the occupied bandwidth of the fundamental emission and a video 
bandwidth of 30 kHz. The power spectral density is the power measured

based on the use of measurement instrumentation employing a resolution 
bandwidth of at least one percent of the occupied bandwidth.
    (m) Emission Mask M. For high power transmitters (greater that 20 
dBm) operating in the 4940-4990 MHz frequency band, the power spectral

average power of the fundamental emission measured across the designated 
channel bandwidth using a resolution bandwidth of at least one percent 
of the occupied bandwidth of the fundamental emission and a video 
bandwidth of 30 kHz. The power spectral density is the power measured 
within the resolution bandwidth of the measurement device divided by the 
resolution bandwidth of the measurement device. Emission levels are also 
based on the use of measurement instrumentation employing a resolution 
bandwidth of at least one percent of the occupied bandwidth.

    Note to paragraph (m): Low power devices may as an option, comply 
with paragraph (m).

    (n) Other frequency bands. Transmitters designed for operation under 
this part on frequencies other than listed in this section must meet the 
emission mask requirements of Emission Mask B. Equipment operating under 
this part on frequencies allocated to but shared with the Federal 
Government, must meet the applicable Federal Government technical 
standards.
    (o) Instrumentation. The reference level for showing compliance with 
the emission mask shall be established, except as indicated in 
Sec. Sec.  90.210 (d), (e), and (k), using standard engineering 
practices for the modulation characteristic used by the equipment under 
test. When measuring emissions in the 150-174 MHz and 421-512 MHz bands 
the following procedures will apply. A sufficient number of sweeps must 
be measured to insure that the emission profile is developed. If video 
filtering is used, its bandwidth must not be less than the instrument 
resolution bandwidth. For frequencies more than 50 kHz removed from the 
edge of the authorized bandwidth a resolution of at least 100 kHz must 
be used for frequencies below 1000 MHz. Above 1000 MHz the resolution 
bandwidth of the instrumentation must be at least 1 MHz. If it can be 
shown that use of the above instrumentation settings do not accurately 
represent the true interference potential of the equipment under test, 
then an

[[Page 346]]

alternate procedure may be used provided prior Commission approval is 
obtained.

Sec.  90.215  Transmitter measurements.

    (a) The licensee of each station shall employ a suitable procedure 
to determine that the carrier frequency of each transmitter authorized 
to operate with an output power in excess of two watts is maintained 
within the tolerence prescribed in Sec.  90.213. This determination 
shall be made, and the results entered in the station records in 
accordance with the following:
    (1) When the transmitter is initially installed;
    (2) When any change is made in the transmitter which may affect the 
carrier frequency or its stability.
    (b) The licensee of each station shall employ a suitable procedure 
to determine that each transmitter authorized to operate with an output 
power in excess of two watts does not exceed the maximum figure 
specified on the current station authorization. On authorizations 
stating only the input power to the final radiofrequency stage, the 
maximum permissible output power is 75 percent for frequencies below 25 
MHz and 60 percent of the input power for frequencies above 25 MHz. If a 
non-DC final radiofrequency stage is utilized, then the output power 
shall not exceed 75 percent of the input power. This determination shall 
be made, and the results thereof entered into the station records, in 
accordance with the following:
    (1) When the transmitter is initially installed;
    (2) When any change is made in the transmitter which may increase 
the transmitter power input.
    (c) The licensee of each station shall employ a suitable procedure 
to determine that the modulation of each transmitter, which is 
authorized to operate with an output power in excess of two watts, does 
not exceed the limits specified in this part. This determination shall 
be made and the following results entered in the station records, in 
accordance with the following:
    (1) When the transmitter is initially installed;
    (2) When any change is made in the transmitter which may affect the 
modulation characteristics.
    (d) The determinations required by paragraphs (a), (b), and (c) of 
this section may, at the opinion of the licensee, be made by a qualified 
engineering measurement service, in which case the required record 
entries shall show the name and address of the engineering measurement 
service as well as the name of the person making the measurements.
    (e) In the case of mobile transmitters, the determinations required 
by paragraphs (a) and (c) of this section may be made at a test or 
service bench: Provided, That the measurements are made under load 
conditions equivalent to actual operating conditions; and provided 
further, that after installation in the mobile unit the transmitter is 
given a routine check to determine that it is capable of being received 
satisfactorly by an appropriate receiver.



Sec.  90.217  Exemption from technical standards.

    Except as noted herein, transmitters used at stations licensed below 
800 MHz on any frequency listed in subparts B and C of this part or 
licensed on a business category channel above 800 MHz which have an 
output power not exceeding 120 milliwatts are exempt from the technical 
requirements set out in this subpart, but must instead comply with the 
following:
    (a) For equipment designed to operate with a 25 kHz channel 
bandwidth, the sum of the bandwidth occupied by the emitted signal plus 
the bandwidth required for frequency stability shall be adjusted so that 
any emission appearing on a frequency 40 kHz or more removed from the 
assigned frequency is attenuated at least 30 dB below the unmodulated 
carrier.
    (b) For equipment designed to operate with a 12.5 kHz channel 
bandwidth, the sum of the bandwidth occupied by the emitted signal plus 
the bandwidth required for frequency stability shall be adjusted so that 
any emission appearing on a frequency 25 kHz or more removed from the

Sec.  90.219  Use of signal boosters.

    This section contains technical and operational rules allowing the 
use of signal boosters in the Private Land Mobile Radio Services 
(PLMRS). Rules for signal booster operation in the Commercial Mobile 
Radio Services under part 90 are found in Sec.  20.21 of this chapter.
    (a) Definitions. The definitions in this paragraph apply only to the 
rules in this section.
    Class A signal booster. A signal booster designed to retransmit 
signals on one or more specific channels. A signal booster is deemed to 
be a Class A signal booster if none of its passbands exceed 75 kHz.
    Class B signal booster. A signal booster designed to retransmit any 
signals within a wide frequency band. A signal booster is deemed to be a 
Class B signal booster if it has a passband that exceeds 75 kHz.
    Coverage area of a PLMRS station. All locations within the normal 
reliable operating range (service contour) of a PLMRS station.
    Deploy a signal booster. Install and/or initially adjust a signal 
booster.
    Distributed Antenna System (DAS). A network of spatially separated 
antenna nodes connected to a common source via a transport medium that 
provides wireless service within a geographic area or structure.
    Operate a signal booster. Maintain operational control over, and 
responsibility for the proper functioning of, a signal booster.
    Signal booster. A device or system that automatically receives, 
amplifies, and retransmits signals from wireless stations into and out 
of building interiors, tunnels, shielded outdoor areas and other 
locations where these signals would otherwise be too weak for reliable 
communications. Signal booster systems may contain both Class A and 
Class B signal boosters as components.
    (b) Authority to operate. PLMRS licensees for stations operating on 
assigned channels higher than 150 MHz may operate signal boosters, 
limited to the service band for which they are authorized, as needed 
anywhere within the PLMRS stations' service contour, but may not extend 
the stations' service contour.
    (1) PLMRS licensees may also consent to operation of signal boosters 
by non-licensees (such as a building owner or a signal booster 
installation contractor) within their service contour and across their 
applicable frequencies, but must maintain a reasonable level of control 
over these operations in order to resolve interference problems.
    (i) Non-licensees seeking to operate signal boosters must obtain the 
express consent of the licensee(s) of the frequencies for which the 
device or system is intended to amplify. The consent must be maintained 
in a recordable format that can be presented to an FCC representative or 
other relevant licensee investigating interference.
    (ii) Consent is not required from third party (unintended) licensees 
whose signals are incidentally retransmitted. However, signal booster 
operation is on a non-interference basis and operations may be required 
to cease or alter the operating parameters due to a request from an FCC 
representative or a licensee's request to resolve interference.
    (2) [Reserved]
    (c) Licensee responsibility; interference. PLMRS licensees that 
operate signal boosters are responsible for their proper operation, and 
are responsible for correcting any harmful interference that signal 
booster operation may cause to other licensed communications services. 
Normal co-channel transmissions are not considered to be

[[Page 350]]

harmful interference. Licensees are required to resolve interference 
problems pursuant to Sec.  90.173(b). Licensees shall act in good faith 
regarding the operation of signal boosters and in the resolution of 
interference due to signal booster operation. Licensees who are unable 
to determine the location or cause of signal booster interference may 
seek assistance from the FCC to resolve such problems.
    (d) Deployment rules. Deployment of signal boosters must be carried 
out in accordance with the rules in this paragraph.
    (1) Signal boosters may be used to improve coverage in weak signal 
areas only.
    (2) Signal boosters must not be used to extend PLMRS stations' 
normal operating range.
    (3)(i) Except as set forth in paragraph (d)(3)(ii) of this section, 
signal boosters must be deployed such that the radiated power of each 
retransmitted channel, on the forward link and on the reverse link, does 
not exceed 5 Watts effective radiated power (ERP).
    (ii) Railroad licensees may operate Class A signal boosters 
transmitting on a single channel with up to 30 Watts ERP on frequencies 
452/457.9000 to 452/457.96875 MHz in areas where communication between 
the front and rear of trains is unsatisfactory due to distance or 
intervening terrain barriers.
    (4) Class B signal boosters may be deployed only at fixed locations; 
mobile operation of Class B signal boosters is prohibited after November 
1, 2014.
    (5) Class B signal booster installations must be registered in the 
FCC signal booster database that can be accessed at the following URL: 
www.fcc.gov/ signal-boosters/ registration.
    (6) Good engineering practice must be used in regard to the 
radiation of intermodulation products and noise, such that interference 
to licensed communications systems is avoided. In the event of harmful 
interference caused by any given deployment, the FCC may require 
additional attenuation or filtering of the emissions and/or noise from 
signal boosters or signal booster systems, as necessary to eliminate the 
interference.
    (i) In general, the ERP of intermodulation products should not 
exceed -30 dBm in 10 kHz measurement bandwidth.
    (ii) In general, the ERP of noise within the passband should not 
exceed -43 dBm in 10 kHz measurement bandwidth.
    (iii) In general, the ERP of noise on spectrum more than 1 MHz 
outside of the passband should not exceed -70 dBm in a 10 kHz 
measurement bandwidth.
    (7) Signal booster passbands are limited to the service band or 
bands for which the operator is authorized. In general, signal boosters 
should utilize the minimum passband that is sufficient to accomplish the 
purpose. Except for distributed antenna systems (DAS) installed in 
buildings, the passband of a Class B booster should not encompass both 
commercial services (such as ESMR and Cellular Radiotelephone) and part 
90 Land Mobile and Public Safety Services.
    (e) Device Specifications. In addition to the general rules for 
equipment certification in Sec.  90.203(a)(2) and part 2, subpart J of 
this chapter, a signal booster must also meet the rules in this 
paragraph.
    (1) The output power capability of a signal booster must be designed 
for deployments providing a radiated power not exceeding 5 Watts ERP for 
each retransmitted channel.
    (2) The noise figure of a signal booster must not exceed 9 dB in 
either direction.
    (3) Spurious emissions from a signal booster must not exceed -13 dBm 
within any 100 kHz measurement bandwidth.
    (4) A signal booster must be designed such that all signals that it 
retransmits meet the following requirements:
    (i) The signals are retransmitted on the same channels as received. 
Minor departures from the exact provider or reference frequencies of the 
input signals are allowed, provided that the retransmitted signals meet 
the requirements of Sec.  90.213.
    (ii) There is no change in the occupied bandwidth of the 
retransmitted signals.
    (iii) The retransmitted signals continue to meet the unwanted 
emissions limits of Sec.  90.210 applicable to the corresponding 
received signals (assuming

[[Page 351]]

that these received signals meet the applicable unwanted emissions 
limits by a reasonable margin).
    (5) On or after March 1, 2014, a signal booster must be labeled to 
indicate whether it is a Class A or Class B device, and the label must 
include the following advisory
    (1) In on-line point-of-sale marketing materials,
    (2) In any print or on-line owner's manual and installation 
instructions,
    (3) On the outside packaging of the device, and
    (4) On a label affixed to the device:
    ``WARNING. This is NOT a CONSUMER device. It is designed for 
installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an 
FCC LICENSE or express consent of an FCC Licensee to operate this 
device. You MUST register Class B signal boosters (as defined in 47 CFR 
90.219) online at www.fcc.gov/ signal-boosters/ registration. 
Unauthorized use may result in significant forfeiture penalties, 
including penalties in excess of $100,000 for each continuing 
violation.''

modified, or withdrawn by the Commission without prior notice or right 
to hearing if necessary to resolve interference conflicts, to implement 
agreements with foreign governments, or in other circumstances 
warranting such action.
    (5) The transmitting site of each Travelers' Information Station 
shall be restricted to the immediate vicinity of the following specified 
areas: Air, train, and bus transportation terminals, public parks and 
historical sites, bridges, tunnels, and any intersection of a Federal 
Interstate Highway with any other Interstate, Federal, State, or local 
highway.
    (6) A Travelers' Information Station shall normally be authorized to 
use a single transmitter. However, a system of stations, with each

device that will deactivate the station not more than 3 minutes after 
its activation by a mobile unit.
    (5) In the Industrial/Business Pool, on frequencies designated with 
an ``LR'' in the coordinator column of the frequency table in Sec.  
90.35(b)(3), each mobile relay station, regardless of the frequency or 
frequencies of the signal by which it is activated shall be so 
designated and installed that it will be deactivated automatically when 
its associated receiver or receivers are not receiving a signal on the 
frequency or frequencies which normally activate it.
    (6) Multiple mobile relay station radio systems shall use wireline 
or radio stations on fixed frequencies for any necessary interconnect 
circuits between the mobile relay stations.

Sec.  90.245  Fixed relay stations.

    Except where specifically provided for, fixed relay stations shall 
be authorized to operate only on frequencies available for use by 
operational fixed stations.



Sec.  90.247  Mobile repeater stations.

    A mobile station authorized to operate on a mobile service frequency 
above 25 MHz may be used as a mobile repeater to extend the 
communications range of hand-carried units subject to the following:
    (a) Mobile repeaters and/or associated hand-carried transmitters may 
be assigned separate base/mobile frequencies for this use in addition to 
the number of frequencies normally assignable to the licensee.
    (b)-(c) [Reserved]
    (d) In the Industrial/Business Pool, on frequencies designated with 
an ``LR'' in the coordinator column of the frequency table in Sec.  
90.35(b)(3), use of mobile repeaters is on a secondary basis to the 
stations of any other licensee. Hand carried units used in connection 
with mobile repeaters on frequencies designated with an ``LR'' in the 
coordinator column of the frequency table in Sec.  90.35(b)(3) may 
operate only above 150 MHz and are limited to a maximum output power of 
six watts. The frequency and maximum power shall be specified in the 
station authorization.
    (e) In the Industrial/Business Pool, on frequencies designated with 
an ``LR'' in the coordinator column of the frequency table in Sec.  
90.35(b)(3), the output power of a mobile repeater station, when 
transmitting as a repeater station on the frequency used for 
communication with its associated pack-carried or hand-carried units, 
shall not exceed 6 watts except when the same frequency is also used by 
the same station for direct communication with vehicular mobile units or 
with one or more base stations.
    (f) When automatically retransmitting messages originated by or 
destined for hand-carried units, each mobile station shall activate the 
mobile transmitter only with a continuous access signal, the absence of 
which will de-activate the mobile transmitter. The continuous access 
signal is not required when the mobile unit is equipped with a switch 
that activates the automatic mode of the mobile unit and an automatic 
time-delay device that de-activates the transmitter after any 
uninterrupted transmission period in excess of 3 minutes. For the 
purposes of this rule section the continuous access signal can be 
achieved by use of digital or analog methods.

sufficient to ensure that, at the carrier frequency employed, the sum of 
the authorized bandwidth plus the bandwidth required for frequency 
stability are confined within this band.
    (2) In the 216-220 MHz frequency band, transmitters shall employ a 
minimum frequency stability of 0.005 percent (50 parts per million). The 
carrier frequency shall be selected to ensure that the sum of the 
authorized bandwidth plus the bandwidth required for frequency stability 
are confined within this band.
    (3) The frequency stability standards shall be met over a 
temperature range of -30[deg] to + 50[deg] centigrade at normal supply 
voltage and for a variation in the primary supply voltage from 85% to 
115% of the rated supply voltage at a temperature of + 20 [deg]C. For 
battery operated equipment, the equipment tests shall be performed using 
a new battery.

at the option of the applicant, be assigned the frequency of the 
associated mobile station. In the Industrial/Business Pool, on 
frequencies designated with an ``LR'' in the coordinator column of the 
frequency table in Sec.  90.35(b)(3), such a control station may be 
assigned any mobile service station frequency available for assignment 
to mobile stations. Such operation is on a secondary basis to use of the 
frequency for regular mobile service communications.
    (3) Control and fixed stations in the Public Safety Pool may be 
authorized on a temporary basis to operate on frequencies available for 
base and mobile stations between 152 and 450 MHz, where there is an 
adequate showing that such operations cannot be conducted on frequencies 
allocated for assignment to operational fixed stations. Such operation 
will not be authorized initially or renewed for periods in excess of one 
year. Any such authorization shall be subject to immediate termination 
if harmful interference is caused to stations in the mobile service, or 
if the particular frequency is required for mobile service operations in 
the area concerned.
    (b) [Reserved]
    (c) A base station which is used intermittently as a control station 
for one or more associated mobile relay stations of the same licensee 
shall operate only on the mobile service frequency assigned to the 
associated mobile relay station when operating as a base station and on 
the mobile service frequency assigned to the associated mobile station 
when operating as a control station. Authority for such dual 
classification and use must be shown on the station authorization. When 
operating as a control station, the licensee must meet all control 
station requirements. In the Industrial/Business Pool, on frequencies

    (2) All authorizations are subject to the condition that no harmful 
interference will be caused to television reception on Channels 4 and 5.
    (3) The applicant must agree to eliminate any harmful interference 
caused by his operation to TV reception on either Channel 4 or 5 that 
might develop by whatever means are necessary. Such action must be taken 
within 90 days of notification by the Commission. If such interference 
is not eliminated within the 90-day period, operation of the fixed 
station will be discontinued.
    (4) Vertical polarization must be used.
    (5) Whenever it is proposed to locate a 72-76 MHz fixed station less 
than 128 km (80 mi.) but more than 16 km (10 mi.) from the site of a TV 
transmitter operating on either channel 4 or 5, or from the post office 
of a community in which such channels are assigned but not in operation, 
the fixed station shall be authorized only if there are fewer than 100 
family dwelling units (as defined by the U.S. Bureau of the Census), 
excluding units 112 or more km (70 mi.) distant from the TV antenna 
site, located within a circle centered at the location of the proposed 
fixed station. The radius shall be determined by use of the following 
chart entitled, ``Chart for Determining Radius From Fixed Station in 72-
76 MHz Band to Interference Contour Along Which 10 Percent of Service 
From Adjacent Channel Television Station Would Be Destroyed.'' Two 
charts are available, one for Channel 4, and one for Channel 5. The 
Commission may, however, in a particular case, authorize the location of 
a fixed station within a circle containing 100 or more family dwelling 
units upon a showing that:
    (i) The proposed site is the only suitable location.
    (ii) It is not feasible, technically or otherwise, to use other 
available frequencies.
    (iii) The applicant has a plan to control any interference that 
might develop to TV reception from his operations.
    (iv) The applicant is financially able and agrees to make such 
adjustments in the TV receivers affected as may be necessary to 
eliminate any interference caused by his operations.
    (v) All applications seeking authority to operate with a separation 
of less than 16 km (10 mi.) will be returned without action.
    (b) The following criteria governs the authorization and use of 
frequencies in the 72-76 MHz band by mobile stations in the Industrial/
Business Pool.
    (1) Mobile operation on frequencies in the 72-76 MHz band is subject 
to the condition that no interference is caused to the reception of 
television stations operating on Channel 4 or 5. Interference will be 
considered to occur whenever reception of a regularly used television 
signal is impaired by signals radiated by stations operating under these 
rules in the 72 to 76 MHz band regardless of the quality of such 
reception or the strength of the signal used. In order to minimize the 
hazard of such interference, it shall be the duty of the

[[Page 362]]

licensee to determine whether interference is being caused to television 
reception, wherever television receivers other than those under the 
control of the licensee, are located within 31 m. (100 ft.) of any point 
where the stations licensed under these rules may be operated. In any 
case, it shall be the responsibility of the licensee to correct, at its 
own expense, any such interference and if the interference cannot be 
eliminated by the application of suitable techniques, the operation of 
the offending transmitter shall be suspended. If the complainant refuses 
to permit the licensee to apply remedial techniques which demonstrably 
will eliminate the interference without impairment of the original 
reception, the licensee is absolved of further responsibility.
    (2) The maximum transmitter output power that will be authorized is 
1 watt; and each station authorized will be classified and licensed as a 
mobile station. Any units of such a station, however, may be used to 
provide the operational functions of a base or fixed station. The 
antennas of transmitters operating on these frequencies must be directly 
mounted or installed upon the transmitting unit: Except that when 
permanently installed aboard a vehicle, antenna and transmitter may be 
separated as required for convenience in mounting. Horizontal 
polarization will not be allowed; and the gain of antennas employed 
shall not exceed that of a halfwave dipole. The maximum bandwidth that 
will be authorized is 20 kHz. Tone control transmissions are permitted.
    (c) Radio remote control of models is permitted on frequencies 10 
kHz removed from these frequencies authorized for fixed and mobile 
operations in the 72-76 MHz band. Remote control operations are 
secondary to operation of fixed and mobile stations as provided for in 
this section.

Sec.  90.263  Substitution of frequencies below 25 MHz.

    Frequencies below 25 MHz when shown in the radio pool frequency 
listings under this part will be assigned to base or mobile stations 
only upon a satisfactory showing that, from a safety of life standpoint, 
frequencies above 25 MHz will not meet the operational requirements of 
the applicant. These frequencies are available for assignment in many 
areas; however, in individual cases such assignment may be impracticable 
due to conflicting frequency use authorized to stations in other 
services by this and other countries. In such cases, a substitute 
frequency, if found available, may be assigned from the following bands: 
1705-1750 kHz, 2107-2170 kHz, 2194-2495 kHz, 2506-2850 kHz, 3155-3400 
kHz, or 4438-4650 kHz. Since such assignments are in certain instances 
subject to additional technical and operation limitations, it is 
necessary that each application also include precise information 
concerning transmitter output power, type and directional 
characteristics, if any, of the antenna, and the minimum necessary hours 
of operation. (This section is not applicable to the Radiolocation 
Service, subpart F of this part.)

    (b) Only in the following circumstances will authority be extended 
to stations to operate on the frequencies between 2 and 10 MHz:
    (1) To provide communications circuits in emergency and/or disaster 
situations, where safety of life and property are concerned;

[[Page 368]]

    (2) To provide standby and/or backup communications circuits to 
regular domestic communications circuits which have been disrupted by 
disasters and/or emergencies.
    (c) The FCC will not accept responsibility for protection of the 
circuits from harmful interference caused by foreign operations.
    (d) In the event that a complaint of harmful interference resulting 
from operation of these circuits is received from a foreign source, the 
offending circuit(s) must cease operation on the particular frequency 
concerned immediately upon notification by the Commission.
    (e) In order to accomodate the situations described in paragraphs 
(c) and (d) of this section, the equipment shall be capable of 
transmitting and receiving on any frequency within the bands between 2 
and 10 MHz and capable of immediate change among the frequencies.
    (f) Only 2K80J3E, 100HA1A and those emission types listed in Sec.  
90.237(g) are permitted.
    (g) Applicants must fulfill eligibility requirements set out in 
Sec.  90.20(d)(6) and shall submit disaster communications plans 
pursuant to Sec.  90.129(m).
    (h) Training exercises which require use of these frequencies for 
more than seven hours a week, cumulative, are not authorized without 
prior written approval from the Commission.

Sec.  90.266  Long distance communications on frequencies below 25 MHz.

    (a) The use of any particular frequency between 2 and 25 MHz is 
limited to those frequencies falling within the bands allocated to the 
fixed and land mobile services as indicated in Sec.  2.106 of the 
Commission's Rules and Regulations.
    (b) Only in the following circumstances will authority be extended 
to stations to operate on the frequencies below 25 MHz:
    (1) To provide communications circuits to support operations which 
are highly important to the national interest and where other means of 
telecommunication are unavailable;
    (2) To provide standby and/or backup communications circuits to 
regular domestic communications circuits which have been disrupted by 
disasters and/or emergencies.
    (c) No protection is afforded to users of these frequencies from 
harmful interference caused by foreign operations.
    (d) In the event that a complaint of harmful interference resulting 
from operation of these circuits is received from a foreign source, the 
offending circuit(s) must cease operation on the particular frequency 
concerned immediately upon notification by the Commission.
    (e) In order to accommodate the situations described in paragraphs 
(c) and (d) of this section, the equipment shall be capable of 
transmitting and receiving on any frequency within the bands between 2 
and 25 MHz and capable of immediate change among the frequencies, 
provided, however, that this requirement does not apply to equipment 
manufactured prior to August 15, 1983.
    (f) Only 2K80J3E, 100HA1A, 100HA1B and those emission types listed 
in Sec.  90.237(g) are permitted.
    (g) Applicants must fulfill eligibility requirements set out in 
Sec.  90.35(c)(1) and submit communications plans pursuant to Sec.  
90.129(o).
    (h) Exercises or circuits tests which require use of these 
frequencies for more than seven hours per week cumulative are prohibited 
unless prior written approval is obtained from the Commission.

Sec.  90.267  Assignment and use of frequencies in the 450-470 MHz band 
for low power use.

    (a) The following frequencies between 450-470 MHz are designated for 
low-power use subject to the provisions of this section. For purposes of 
this section these frequencies are referred to as ``low power 
frequencies.'' Pairs are shown but single frequencies are available for 
simplex operations.
    (b) Group A1 Frequencies. The Industrial/Business Pool frequencies 
in Group A1 are available on a coordinated basis, pursuant to Sec. Sec.  
90.35(b)(2) and 90.175(b), as follows:
    (1) Group A1 frequencies are available for voice and non-voice 
operations on a co-primary basis. Base, mobile and operational fixed 
stations will be authorized on Group A1 frequencies. Fixed stations may 
be licensed as mobile.
    (2) Within 80 kilometers (50 miles) of the specified coordinates of 
the top 100 urban areas listed in Sec.  90.741 of this chapter (``80 km 
circles'') only low power operation will be authorized. The coordinates 
of an operational fixed

Sec.  90.279  Power limitations applicable to the 421-430 MHz band.

    (a) Base station authorizations in the 421-430 MHz band will be 
subject to Effective Radiated Power (ERP) and Effective Antenna Height 
(EAH) limitations as shown in the table below. ERP is defined as the 
product of the power supplied to the antenna and its gain relative to a 
half-wave dipole in a given direction. EAH is calculated by subtracting 
the Assumed Average Terrain Elevation (AATE) as listed in table 7 of 
Sec.  90.619 from the antenna height above mean sea level.

[69 FR 31907, June 8, 2004, as amended 72 FR 35196, June 27, 2007]



Sec.  90.305  Location of stations.

    (a) The transmitter site(s) for base station(s), including mobile 
relay stations, shall be located not more than 80 km. (50 mi.) from the 
geographic center of the urbanized area listed in Sec.  90.303.
    (b) Mobile units shall be operated within 48 km. (30 mi.) of their 
associated base station or stations. Such units may not be operated 
aboard aircraft in flight except as provided for in Sec.  90.315(i).
    (c) Control stations must be located within the area of operation of 
the mobile units.
    (d) Base and control stations shall be located a minimum of 1.6 km. 
(1 mi.) from local television stations operating on UHF TV channels 
separated by 2, 3, 4, 5, 7, and 8 TV channels from the television 
channel in which the base station will operate.



Sec.  90.307  Protection criteria.

    The tables and figures listed in Sec.  90.309 shall be used to 
determine the effective radiated power (ERP) and antenna height of the 
proposed land mobile base station and the ERP for the associated control 
station (control station antenna height shall not exceed 31

[[Page 383]]

meters (100 feet) above average terrain (AAT)).
    (a) Base stations operating on the frequencies available for land 
mobile use in any urbanized area and having an antenna height (AAT) less 
than 152 meters (500 feet) shall afford protection to co-channel and 
adjacent channel television stations in accordance with the values set 
out in tables A and E of Sec.  90.309, except for channel 15 in New 
York, NY, and Cleveland, OH, and channel 16 in Detroit, MI, where 
protection will be in accordance with the values set forth in tables B 
and E in 47 CFR 90.309.
    (b) For base stations having antenna heights between 152 and 914 
meters (500-3000 feet) above average terrain, the effective radiated 
power must be reduced below 1 kilowatt in accordance with the values 
shown in the power reduction graph in Figure A in Sec.  90.309, except 
for channel 15 in New York, NY, and Cleveland, OH, and channel 16 in 
Detroit, MI, where the effective radiated power must be reduced in 
accordance with Figure B in Sec.  90.309. For heights of more than 152 
meters (500 feet) above average terrain, the distance to the radio path 
horizon will be calculated assuming smooth earth. If the distance so 
determined equals or exceeds the distance to the Grade B contour of a 
co-channel TV station (Grade B contour defined in Sec.  73.683(a) of 
this chapter), an authorization will not be granted unless it can be 
shown that actual terrain considerations are such as to provide the 
desired protection at the Grade B contour, or that the effective 
radiated power will be further reduced so that, assuming free space 
attenuation, the desired protection at the Grade B contour will be 
achieved.
    (c) Mobile units and control stations operating on the frequencies 
available for land mobile use in any given urbanized area shall afford 
protection to co-channel and adjacent channel television stations in 
accordance with the values set forth in table C in Sec.  90.309 and 
paragraph (d) of this section except for channel 15 in New York, NY, and 
Cleveland, OH, and channel 16 in Detroit, MI, where protection will be 
in accordance with the values set forth in table D in Sec.  90.309 and 
paragraph (d) of this section.
    (d) The minimum distance between a land mobile base station which 
has associated mobile units and a protected adjacent channel television 
station is 145 km (90 miles).
    (e) The television stations to be protected (co-channel, adjacent 
channel, IM, and IF) in any given urbanized area, in accordance with the 
provisions of paragraphs (a), (b), (c), and (d) of this section, are 
identified in the Commission's publication ``TV stations to be 
considered in the preparation of Applications for Land Mobile Facilities 
in the Band 470-512 MHz.'' The publication is available at the offices 
of the Federal Communications Commission in Washington, DC or upon the 
request of interested persons.

[72 FR 35197, June 27, 2007]



Sec.  90.309  Tables and figures.

    (a) Directions for using the tables. (1) Using the method specified 
in Sec.  1.958 of this chapter, determine the distances between the 
proposed land mobile base station and the protected co-channel 
television station and between the proposed land mobile base station and 
the protected adjacent channel television station. If the exact mileage 
does not appear in table A for protected co-channel television stations 
(or table B for channel 15 in New York and Cleveland and channel 16 in 
Detroit) or table E for protected adjacent channel television stations, 
the next lower mileage separation figure is to be used.
    (2) Entering the proper table at the mileage figure found in 
paragraph (a)(1) of this section, find opposite, a selection of powers 
that may be used for antenna heights ranging from 15 m (50 ft) to 152.5 
m (500 ft) (AAT). If the exact antenna height proposed for the land 
mobile base station does not appear in the proper table, use the power 
figure beneath the next greater antenna height.
    (3) The lowest power found using the tables mentioned in paragraphs 
(a)(1) and (a)(2) of this section is the maximum power that may be 
employed by the proposed land mobile base station.
    (4) In determining the average elevation of the terrain, the 
elevations between 3.2 kilometers (2 miles) and 16

[[Page 384]]

kilometers (10 miles) from the antenna site are employed. Profile graphs 
shall be drawn for a minimum of eight radials beginning at the antenna 
site and extending 16 kilometers (10 miles). The radials should be drawn 
starting with true north. At least one radial should be constructed in 
the direction of the nearest co-channel and adjacent channel UHF 
television stations. The profile graph for each radial shall be plotted 
by contour intervals of from 12.2 meters (40 feet) to 30.5 meters (100 
feet) and, where the data permits, at least 50 points of elevation 
(generally uniformly spaced) should be used for each radial. For very 
rugged terrain, 61 meters (200 feet) to 122 meters (400 foot) contour 
intervals may be used. Where the terrain is uniform or gently sloping, 
the smallest contour interval indicated on the topographic chart may be 
used. The average elevation of the 12.8 kilometer (8 mile) distance 
between 3.2 kilometers (2 miles) and 16 kilometers (10 miles) from the 
antenna site should be determined from the profile graph for each 
radial. This may be obtained by averaging a large number of equally 
spaced points, by using a planimeter, or by obtaining the median 
elevation (that exceeded by 50 percent of the distance) in sectors and 
averaging those values. In the preparation of the profile graphs, the 
elevation or contour intervals may be taken from U.S. Geological Survey 
Topographic Maps, U.S. Army Corps of Engineers Maps, or Tennessee Valley 
Authority Maps. Maps with a scale of 1:250,000 or larger (such as 
1:24,000) shall be used. Digital Terrain Data Tapes, provided by the 
National Cartographic Institute, U.S. Geologic Survey, may be utilized 
in lieu of maps, but the number of data points must be equal to or 
exceed that specified above. If such maps are not published for the area 
in question, the next best topographic information should be used.
    (5) Applicants for base stations in the Miami, FL, urbanized area 
may, in lieu of calculating the height of average terrain, use 3 m (10 
ft) as the average terrain height.

    (b) Directions for Using the Figures. (1) Determine antenna height 
above average terrain. (According to Sec.  90.309(a)(4).)
    (2) Locate this value on the antenna height axis.
    (3) Determine the separation between the LM antenna site and the 
nearest protected co-channel TV station. (According to Sec.  73.611.)
    (4) Draw a vertical line to intersect the LM/TV separation curve at 
the distance determined in step 3 above. For distances not shown in the 
graph use linear interpolation.
    (5) From the intersection of the LM/TV separation curve draw a 
horizontal line to the power reduction scale.
    (6) The power reduction in dB determines the reduction below 1 kW 
that must be achieved.
    (7) See table F for dB/power equivalents.

Sec.  90.313  Frequency loading criteria.

    (a) Except as provided for in paragraph (b) of this section, the 
maximum channel loading on frequencies in the 470-512 MHz band is as 
follows:
    (1) 50 units for systems eligible in the Public Safety Pool (see 
Sec.  90.20(a)).
    (2) 90 units for systems eligible in the Industrial/Business Pool 
(see Sec.  90.35(a)).
    (b) If a licensee has exclusive use of a frequency, then the loading 
standards in paragraph (a) of this section, may be exceeded. If it is a 
shared channel, the loading standards can be exceeded upon submission of 
a signed statement by all those sharing the channel agreeing to the 
increase.
    (c) A unit is defined as a mobile transmitter-receiver. Loading 
standards will be applied in terms of the number of units actually in 
use or to be placed in use within 8 months following authorization. A 
licensee will be required to show that an assigned frequency pair is at 
full capacity before it may be assigned a second or additional frequency 
pair. Channel capacity may be reached either by the requirements of a 
single licensee or by several users sharing a channel. Until a channel 
is loaded to capacity it will be available for assignment to other users 
in the same area. A frequency pair may be reassigned at distances 64 km. 
(40 mi.), 32 km. (20 mi.) for Channel 15, Chicago; Channel 20, 
Philadelphia; and Channel 17, Washington, or more from the location of 
base stations authorized on that pair without reference to loading at 
the point of original installation. Following authorization, the 
licensee shall notify the Commission either during or at the close of 
the 8 month period of the number of units in operation. In the 
Industrial Radio Services, if the base station facility is to be used by 
more than a single licensee, the frequency assigned to it will not be 
reassigned for use by another facility within 64 km. (40 mi.) or 32 km. 
(20 mi.) where applicable for a period of 12 months, Provided, That the 
facility is constructed within 90 days from the date of the first grant, 
meets the loading standards to at least 50 percent within 9 months, and 
meets all loading standards within 12 months.

    Note: To determine the maximum permissible effective radiated power:
    (1) As specified in Sec.  73.611 determine the distance between the 
proposed station and the cochannel television station. If the exact 
distance does not appear in table 1 of this section, the next lower 
distance separation is to be used.

    (2) Opposite this distance figure ERPs are given that may be used 
for antenna heights of 30.5, 45 or 61 meters (100, 150 or 200 ft) ASL. 
If the exact antenna height is not shown, the ERP allowed will be that 
shown for the next higher antenna height.
    (e) Shore stations communicating point-to-point with offshore 
stations will be permitted at least the same ERP as the offshore 
station, but only in the direction of the offshore station. A 
directional antenna shall be used and the rearward radiated power from 
the antenna in a sector 22\1/2\[deg] from the line 
joining the shore antenna to the cochannel television station shall not 
exceed those shown in table 2 of this section.

    Note: As an example of the use of tables 1 and 2, assume an offshore 
station located 290 km (180 mi) from TV Channel 17 located in Bude, 
Miss. with an antenna height of 30.5 m (100 ft). Table 1 allows this 
station to operate with 250 W ERP. Now assume the shore station 
communicating with the offshore station is 48 km (30 mi) from the 
offshore station and 241 km (150 mi) from Bude, Miss. The shore station 
antenna height is 152.5 m (500 ft) above ground. The shore station will 
be allowed the same ERP as the offshore station (250 W) in the direction 
of the offshore station. Table 2 indicates that the effective radiated 
power in a sector <22\1/2\[deg] from 
the line joining the shore antenna to Bude, Miss. can only be 15 W. 
Consequently, a directional antenna must be used whose minimum front-to-
back ratio over this 45[deg] sector must be at least 12.2 dB. (250 W 
forward power to 15 W rearward power is a power ratio of 16.6 or 12.2 
dB).

    (f) To provide cochannel protection to television stations, no shore 
station will be allowed closer than 193 km miles) from the cochannel 
television station.
    (g) To provide adjacent channel protection to television stations, 
no shore or offshore station shall be allowed within 128 kilometers (80 
miles) of the adjacent channel television station.
    (h) Mobile stations shall not operate closer to shore than 6.4 km (4 
miles) beyond the three mile limit and shall not operate with an ERP in 
excess of 100

watts with 9.1 m (30 ft) maximum antenna height.
    (i) Mobile stations installed in aircraft shall operate 11 km (7 
miles) beyond the three mile limit and shall not operate with an ERP in 
excess of 1 watt or at heights in excess of 305 m (1000 feet) AMSL.
    (j)(1) The following frequency bands are available for assignment in 
all services for use in the Zones defined in paragraph (a) of this

Sec.  90.317  Fixed ancillary signaling and data transmissions.

    (a) Licensees of systems that have exclusive-use status in their 
respective geographic areas may engage in fixed ancillary signaling and 
data transmissions, subject to the following requirements:
    (1) All such ancillary operations must be on a secondary, non-
interference basis to the primary mobile operation of any other 
licensee.
    (2) The output power at the remote site shall not exceed 30 watts.
    (3) Any fixed transmitters will not count toward meeting the mobile 
loading requirements nor be considered in whole or in part as a 
justification for authorizing additional frequencies in the licensee's 
mobile system.
    (4) Automatic means must be provided to deactivate the remote 
transmitter in the event the carrier remains on for a period in excess 
of three minutes.
    (5) Operational fixed stations authorized pursuant to the provisions 
of this paragraph are exempt from the requirements of Sec. Sec.  90.425 
and 90.429.
    (6) If the system is licensed on 470-512 MHz conventional 
frequencies, and exclusivity has been achieved through the aggregate 
loading of more than a single co-channel licensee, then a licensee must 
obtain the concurrence of other co-channel licensees prior to commencing 
such ancillary operations.
    (b) Licensees of systems that do not have exclusive-use status in 
their respective geographic areas may conduct fixed ancillary signaling 
and data transmissions only in accordance with the provisions of Sec.  
90.235 of this part.

Monitoring Service (LMS) and Dedicated Short Range Communications 
Service (DSRCS). Rules as to eligibility for licensing, frequencies 
available, and any special requirements for

[[Page 393]]

services in the Intelligent Transportation Systems radio service are set 
forth in this subpart.

[64 FR 66410, Nov. 26, 1999]



Sec.  90.351  Location and Monitoring Service.

    These provisions authorize the licensing of systems in the Location 
and Monitoring Service (LMS). LMS systems utilize non-voice radio 
techniques to determine the location and status of mobile radio units. 
LMS licensees authorized to operate a system in the 902-928 MHz band may 
serve individuals, federal government agencies, and entities eligible 
for licensing in this part 90.
    (a) Each application to license an LMS system shall include the 
following supplemental information:
    (1) A detailed description of the manner in which the system will 
operate, including a map or diagram.
    (2) The necessary or occupied bandwidth of emission, whichever is 
greater.
    (3) The data transmission characteristics as follows:
    (i) The vehicle location update rates;
    (ii) Specific transmitter modulation techniques used;
    (iii) For codes and timing scheme: A table of bit sequences and 
their alphanumeric or indicator equivalents, and a statement of bit rise 
time, bit transmission rates, bit duration, and interval between bits;
    (iv) A statement of amplitude-versus-time of the interrogation and 
reply formats, and an example of a typical message transmission and any 
synchronizing pulses utilized.
    (4) A plan to show the implementation schedule during the initial 
license term.
    (b) LMS stations are exempted from the identification requirements 
of Sec.  90.425; however, the Commission may impose automatic station 
identification requirements when determined to be necessary for 
monitoring and enforcement purposes.



Sec.  90.353  LMS operations in the 902-928 MHz band.

    LMS systems may be authorized within the 902-928 MHz band, subject 
to the conditions in this section. LMS licensees are required to 
maintain whatever records are necessary to demonstrate compliance with 
these provisions and must make these records available to the Commission 
upon request:
    (a) LMS operations will not cause interference to and must tolerate 
interference from industrial, scientific, and medical (ISM) devices and 
radiolocation Government stations that operate in the 902-928 MHz band.
    (b) LMS systems are authorized to transmit status and instructional 
messages, either voice or non-voice, so long as they are related to the 
location or monitoring functions of the system.
    (c) LMS systems may utilize store and forward interconnection, where 
either transmissions from a vehicle or object being monitored are stored 
by the LMS provider for later transmission over the public switched 
network (PSN), or transmissions received by the LMS provider from the 
PSN are stored for later transmission to the vehicle or object being 
monitored. Real-time interconnection between vehicles or objects being 
monitored and the PSN will only be permitted to enable emergency 
communications related to a vehicle or a passenger in a vehicle. Such 
real-time, interconnected communications may only be sent to or received 
from a system dispatch point or entities eligible in the Public Safety 
or Special Emergency Radio Services. See subparts B and C of this part.
    (d) Multilateration LMS systems will be authorized on a primary 
basis within the bands 904-909.75 MHz and 921.75-927.25 MHz. 
Additionally, multilateration and non-multilateration systems will share 
the 919.75-921.75 MHz band on a co-equal basis. Licensing will be on the 
basis of Economic Areas (EAs) for multilateration systems, with one 
exclusive EA license being issued for each of these three sub-bands. 
Except as provided in paragraph (f) of this section, multilateration EA 
licensees may be authorized to operate on only one of the three 
multilateration bands within a given EA. Additionally, EA 
multilateration LMS licenses will be conditioned upon the licensee's 
ability to demonstrate through actual field tests that their systems do 
not cause

[[Page 394]]

unacceptable levels of interference to 47 CFR part 15 devices.
    (e) Multilateration EA-licensed systems and grandfathered automatic 
vehicle monitoring service (AVM) systems (see Sec.  90.363) are 
authorized on a shared basis and must cooperate in the selection and use 
of frequencies in accordance with Sec.  90.173(b).
    (f) Multilateration EA licensees may be authorized to operate on 
both the 919.75-921.75 MHz and 921.75-927.75 MHz bands within a given EA 
(see Sec.  90.209(b)(5)).
    (g) Multilateration LMS systems whose primary operations involve the 
provision of vehicle location services, may provide non-vehicular 
location services.
    (h) Non-multilateration stations are authorized to operate on a 
shared, non-exclusive basis in the 902-904 MHz and 909.75-921.75 MHz 
sub-bands. Non-multilateration systems and multilateration systems will 
share the 919.75-921.75 MHz band on a co-equal basis. Non-
multilateration LMS systems may not provide non-vehicular location 
services. The maximum antenna height above ground for non-
multilateration LMS systems is 15 meters.
    (i) Non-multilateration LMS licenses will be issued on a site-by-
site basis, except that municipalities or other governmental operatives 
may file jointly for a non-multilateration license covering a given U.S. 
Department of Commerce Bureau of Economic Analysis Economic Area (EA). 
Such an application must identify all planned sites. After receiving the 
license, the non-multilateration EA licensee must notify the Commission 
if sites are deleted or if new sites are added, before those sites may 
be put into operation.

Sec.  90.355  LMS operations below 512 MHz.

    Applications requiring not more than 25 kHz bandwidth per frequency 
in the 25-50 MHz, 150-170 MHz, and 450-512 MHz bands may use either 
base-mobile frequencies currently assigned the applicant, or be assigned 
base-mobile frequencies available in the service in which eligibility 
has been established, provided that:
    (a) For transmission between vehicles and base stations, each 
frequency in a single-frequency mode of operation will provide location 
data for approximately 200 vehicles, or both frequencies in a two-
frequency mode of operation will provide location data for approximately 
400 vehicles, except that for frequencies in the 450-512 MHz band that 
are assigned in pairs in accordance with the allocation plan for the 
band, the requirement is that location data be provided for 
approximately 200 vehicles for each frequency pair; and a showing is 
made that 50 percent of the vehicles will be in operation within the 
system by the end of the second year of the initial license term, and 70 
percent will be in operation within the system by the end of the initial 
license term; except that if these vehicle loading standards will not be 
met, frequencies will be assigned only on a secondary non-interference 
basis to any authorized radiotelephony operation.
    (b) The minimum separation between a proposed LMS station and the 
nearest co-channel base station of another licensee operating a voice 
system is 75 miles (120 km) for a single frequency mode of operation or 
35 miles (56 km) for a two-frequency mode of operation. Where the 
minimum mileage separation cannot be achieved, agreement to the use of 
F1D, F2D, G1D, G2D or P0N emission must be received from all existing 
co-channel licensees using voice emissions within the applicable mileage 
limits. If there is interference with voice operations and required 
agreement was not received, or operation was authorized on a secondary 
non-interference basis, the licensee of the LMS system is responsible 
for eliminating the interference.
    (c) Frequencies additional to any assigned under paragraph (a) of 
this section will not be assigned to the same licensee at any stations 
located within 64 km (40 miles) of any station in which the licensee 
holds an interest until each of such licensee's frequencies for LMS 
operation is shown to accommodate not less than 90 percent of the 
frequency loading requirements specified in paragraph (a) of this

    (b) Any entity meeting the eligibility requirements of Sec. Sec.  
90.33 or 90.35.

[69 FR 46443, Aug. 3, 2004]



Sec.  90.375  RSU license areas, communication zones and registrations

    (a) Roadside Units (RSUs) in the 5895-5925 MHz band are licensed on 
the basis of non-exclusive geographic areas. Governmental applicants 
will be issued a geographic area license based on the geo-political area 
encompassing the legal jurisdiction of the entity. All other applicants 
will be issued a geographic area license for their proposed area of 
operation based on county(s), state(s) or nationwide.
    (b) Applicants who are approved in accordance with FCC Form 601 will 
be granted non-exclusive licenses for all non-reserved DSRCS frequencies 
(see Sec.  90.377). Such licenses serve as a prerequisite of registering 
individual RSUs located within the licensed geographic area described in 
paragraph (a) of this section. Licensees must register each RSU in the 
Universal Licensing System (ULS) before operating such RSU. RSU 
registrations are subject, inter alia, to the requirements of Sec.  
1.923 of this chapter as applicable (antenna structure registration, 
environmental concerns, international coordination, and quiet zones). 
Additionally, RSUs at locations subject to NTIA coordination (see Sec.  
90.371(b)) may not begin operation until NTIA approval is received. 
Registrations are not effective until the Commission posts them on the 
ULS. It is the DSRCS licensee's responsibility to delete from the 
registration database any RSUs that have been discontinued.
    (c) Licensees must operate each RSU in accordance with the 
Commission's rules and the registration data posted on the ULS for such 
RSU. Licensees must register each RSU for the smallest communication 
zone needed for the intelligent transportation systems application using 
one of the following four communication zones:

Commission may impose restrictions including specifying the transmitter 
power, antenna height and direction, additional filtering, or area or 
hours of operation of the stations concerned. Further the use of any 
channel at a given geographical location may be denied when, in the 
judgment of the Commission, its use at that location is not in the 
public interest; use of any such channel may be restricted as to 
specified geographical areas, maximum power, or such other operating 
conditions, contained in this part or in the station authorization.
    (d) Safety/public safety priority. The following access priority 
governs all DSRCS operations:
    (1) Communications involving the safety of life have access priority 
over all other DSRCS communications;
    (2) Subject to a control channel priority system management strategy 
(see ASTM E2213-03 DSRC Standard at

[[Page 400]]

Sec.  4.1.1.2(4)), DSRCS communications involving public safety have 
access priority over all other DSRC communications not listed in 
paragraph (d)(1) of this section. Roadside Units (RSUs) operated by 
state or local governmental entities are presumptively engaged in public 
safety priority communications.
    (e) Non-priority communications. DSRCS communications not listed in 
paragraph (d) of this section, are non-priority communications. If a 
dispute arises concerning non-priority communications, the licensee of 
the later-registered RSU must accommodate the operation of the early 
registered RSU, i.e., interference protection rights are date-sensitive, 
based on the date that the RSU is first registered (see Sec.  90.375) 
and the later-registered RSU must modify its operations to resolve the 
dispute in accordance with paragraph (f) of this section.
    (f) Except as otherwise provided in the ASTM-DSRC Standard (see 
Sec.  90.379) for the purposes of paragraph (e) of this section, 
objectionable interference will be considered to exist when the 
Commission receives a complaint and the difference in signal strength 
between the earlier-registered RSU and the later-registered RSU 
(anywhere within the earlier-registered RSU's communication zone) is 18 
dB or less (co-channel). Later-registered RSUs causing objectionable 
interference must correct the interference immediately unless written 
consent is obtained from the licensee of the earlier-registered RSU.

Sec.  90.401  Scope.

    The subpart prescribes general operating requirements for stations 
licensed under this part. This includes station operating procedures, 
points of communication, permissible communications, methods of station 
identification, control requirements, and station record keeping 
requirements.



Sec.  90.403  General operating requirements.

    (a) Licensees of radio stations in the private land mobile radio 
services shall be directly responsible for the proper operation and use 
of each transmitter for which they are licensed. In this connection, 
licensees shall exercise such direction and control as is necessary to 
assure that all authorized facilities are employed:
    (1) Only for permissible purposes;
    (2) Only in a permissible manner; and
    (3) Only by persons with authority to use and operate such 
equipment.
    (b) In carrying out their responsibilities under Sec.  90.403(a), 
licensees shall be bound by the provisions of the Communications Act of 
1934, as amended, and by the rules and regulations of the Commission 
governing the radio service in which their facilities are licensed; and 
licensees may not, through written or oral agreements or otherwise, 
relieve themselves of any duty or obligation imposed upon them, by law, 
as licensees.
    (c) Except for stations that have been granted exclusive channels 
under this part and that are classified as commercial mobile radio 
service providers pursuant to part 20 of this chapter, each licensee 
must restrict all transmissions to the minimum practical transmission 
time and must employ an efficient operating procedure designed to 
maximize the utilization of the spectrum.
    (d) Communications involving the imminent safety-of-life or property 
are to be afforded priority by all licensees.
    (e) Licensees shall take reasonable precautions to avoid causing 
harmful interference. This includes monitoring the transmitting 
frequency for communications in progress and such other measures as may 
be necessary to minimize the potential for causing interference.
    (f) Stations licensed in this part shall not continuously radiate an 
unmodulated carrier except where required for tests as permitted in 
Sec.  90.405, except where specifically permitted by this part, where 
specifically authorized in the station authorization, or on an as needed 
basis in the Radiolocation Radio Service.
    (g) The radiations of the transmitter shall be suspended immediately 
upon detection or notification of a deviation from the technical 
requirements of the station authorization and until such deviation is 
corrected. For transmissions concerning the imminent safety-of-life or 
property, the transmissions shall be suspended as soon as the emergency 
is terminated.

following types of communication:
    (1) Any communication related directly to the imminent safety-of-
life or property;
    (2) Communications directly related and necessary to those 
activities which make the licensee eligible for the station license held 
under this part. In addition, when communication service is provided 
under the cooperative sharing provisions of Sec.  90.179, the licensee 
providing such service may transmit communications related to the 
activities for which the parties receiving the service would be eligible 
to be licensed.
    (3) Communications for testing purposes required for proper station 
and system maintenance. However, each licensee shall keep such tests to 
a minimum and shall employ every measure to avoid harmful interference.
    (b) The provisions contained in paragraph (a) of this section do not 
apply where a single base station licensee has been authorized to use a 
channel above 470 MHz on an exclusive basis, or to stations licensed 
under this part that are classified as CMRS providers under part 20 of 
this chapter.

other station licensed under this part, with U.S. Government stations, 
and with foreign stations, in connection with mutual activities, 
provided that where the communication involves foreign stations prior 
approval of the Commission must be obtained, and such communication must 
be permitted by the government that authorizes the foreign station. 
Communications by Public Safety Pool eligibles with foreign stations 
will be approved only to be conducted in accordance with Article 5 of 
the Inter-American Radio Agreement, Washington, DC, 1949, the provisions 
of which are set forth in Sec.  90.20(b).

[43 FR 54791, Nov. 22, 1978, as amended at 62 FR 18933, Apr. 17, 1997]



Sec.  90.419  Points of communication.

    Normally, operations licensed under this part are intended to 
provide intrastation mobile communications. For example, a base station 
is intended to communicate with its associated mobile stations and 
mobile stations are intended to communicate between associated mobile 
stations and associated base stations of the licensee. Accordingly, 
operations between base stations at fixed locations are permitted only 
in the following situations:
    (a) Base stations licensed under subpart T of this part and those in 
the Public Safety Pool that operate on frequencies below 450 MHz, may 
communicate on a secondary basis with other base stations, operational 
fixed stations, or fixed receivers authorized in these services or 
pools.
    (b) Base stations licensed on any frequency in the Industrial/
Business Pool and on base stations frequencies above 450 MHz in the 
Public Safety Pool may communicate on a secondary basis with other base 
stations, operational fixed stations, or fixed receivers authorized in 
these pools only when:
    (1) The messages to be transmitted are of immediate importance to 
mobile stations; or
    (2) Wireline communications facilities between such points are 
inoperative, economically impracticable, or unavailable from 
communications common carrier sources. Temporary unavailability due to a 
busy wireline

[[Page 403]]

circuit is not considered to be within the provisions of this paragraph.
    (c) Operational fixed stations may communicate with units of 
associated mobile stations only on a secondary basis.
    (d) Operational fixed stations licensed in the Industrial/Business 
Pool may communicate on a secondary basis with associated base stations 
licensed in these services when:
    (1) The messages to be transmitted are of immediate importance to 
mobile stations; or
    (2) Wireline communications facilities between such points are 
inoperative, economically impracticable, or unavailable from 
communications common carrier sources. Temporary unavailability due to a 
busy wireline circuit is not considered to be within the provisions of 
this paragraph.
    (e) Travelers' Information Stations are authorized to transmit 
certain information to members of the traveling public (see Sec.  
90.242).
    (f) CMRS licensees in the SMR categories of part 90, subpart S, CMRS 
providers authorized in the 220 MHz service of part 90, subpart T, CMRS 
paging operations as defined by part 90, subpart P and for-profit 
interconnected business radio services with eligibility defined by Sec.  
90.35 are permitted to utilize their assigned spectrum for fixed 
services on a co-primary basis with their mobile operations.

[61 FR 45356, Aug. 29, 1996, as amended at 62 FR 18933, Apr. 17, 1997; 
72 FR 35199, June 27, 2007]



Sec.  90.421  Operation of mobile station units not under the control 
of the licensee.

    Mobile stations, as defined in Sec.  90.7, include vehicular-mounted 
and hand-held units. Such units may be operated by persons other than 
the licensee, as provided for below, when necessary for the licensee to 
meet its requirements in connection with the activities for which it is 
licensed. If the number of such units, together with units operated by 
the licensee, exceeds the number of mobile units authorized to the 
licensee, license modification is required. The licensee is responsible 
for taking necessary precautions to prevent unauthorized operation of 
such units not under its control.
    (a) Public Safety Pool. (1) Mobile units licensed in the Public 
Safety Pool may be installed in any vehicle which in an emergency would 
require cooperation and coordination with the licensee, and in any 
vehicle used in the performance, under contract, of official activities 
of the licensee. This provision does not permit the installation of 
radio units in non-emergency vehicles that are not performing 
governmental functions under contract but with which the licensee might 
wish to communicate.
    (2) Mobile units licensed under Sec.  90.20(a)(2)(iii) may be 
installed in a vehicle or be hand-carried for use by any person with 
whom cooperation or coordinations is required for medical services 
activities.
    (3) On the Interoperability Channels in the 700 MHz Public Safety 
Band (See Sec.  90.531(b)(1)), hand-held and vehicular transmitters may 
be operated by any licensee holding a license in the 700 MHz Public 
Safety Band or by any licensee holding a license for any other public 
safety frequency pursuant to part 90 of the Commission's rules. 
Therefore, individual licenses are not required for hand-held and 
vehicular transmitters in the 700 MHz Band.
    (b) Industrial/Business Pool. Mobile units licensed in the 
Industrial/Business Pool may be installed in vehicles of persons 
furnishing under contract to the licensee and for the duration of the 
contract, a facility or service directly related to the activities of 
the licensee.
    (c) In addition to the requirements in paragraphs (a) and (b) of 
this section, frequencies assigned to licensees in the Private Land 
Mobile Radio Services may be installed in the facilities of those who 
assist the licensee in emergencies and with whom the licensee must 
communicate in situations involving imminent safety to life or property.

[65 FR 60877, Oct. 13, 2000, as amended at 66 FR 10635, Feb. 16, 2001]



Sec.  90.423  Operation on board aircraft.

    (a) Except as provided in paragraphs (b), (c), and (d) of this 
section, and except as may be provided in other sections of this part 
with respect to operation on specific frequencies, mobile

[[Page 404]]

stations first authorized after September 14, 1973, under this part may 
be operated aboard aircraft for air-to-mobile, air-to-base, air-to-air 
and air-to-ship communications subject to the following:
    (1) Operations are limited to aircraft that are regularly flown at 
altitudes below 1.6 km (1 mi) above the earth's surface;
    (2) Transmitters are to operate with an output power not to exceed 
ten watts;
    (3) Operations are secondary to land-based systems;
    (4) Such other conditions, including additional reductions of 
altitude and power limitations, as may be required to minimize the 
interference potential to land-based systems.
    (b) Exceptions to the altitude and power limitations set forth in 
paragraph (a) of this section may be authorized upon a showing of 
unusual operational requirements which justify departure from those 
standards, provided that the interference potential to regular land-
based operations would not be increased.
    (c) Mobile operations aboard aircraft in the services governed by 
this part, under licenses in effect September 14, 1973, may be continued 
without regard to provisions of paragraph (a) of this section, as 
follows:
    (1) Operations may be continued only for the balance of the term of 
such licenses if aircraft involved are regularly flown at altitudes 
greater than 1.6 km (1 mi) above the earth's surface.
    (2) Operations may be continued for one additional renewal license 
term if the aircraft involved are regularly flown at altitudes below 1.6 
km (1 mi) above the earth's surface.
    (d) Operation of radiolocation mobile stations may be authorized 
without regard to limitations and conditions set forth in paragraphs 
(a), (b), and (c) of this section.

[43 FR 54791, Nov. 22, 1978, as amended at 58 FR 44960, Aug. 25, 1993]



Sec.  90.425  Station identification.

    Stations licensed under this part shall transmit identification in 
accordance with the following provisions:
    (a) Identification procedure. Except as provided for in paragraphs 
(d) and (e) of this section, each station or system shall be identified 
by the transmission of the assigned call sign during each transmission 
or exchange of transmissions, or once each 15 minutes (30 minutes in the 
Public Safety Pool) during periods of continuous operation. The call 
sign shall be transmitted by voice in the English language or by 
International Morse Code in accordance with paragraph (b) of this 
section. If the station is employing either analog or digital voice 
scrambling, or non-voice emission, transmission of the required 
identification shall be in the unscrambled mode using A3E, F3E or G3E 
emission, or International Morse, with all encoding disabled. 
Permissible alternative identification procedures are as follows:
    (1) A mobile relay stations call sign may be used to identify the 
associated control and mobile stations, except in the Public Safety Pool 
where the stations operate on frequencies below 450 MHz. Alternatively, 
a base station (including a mobile relay station) which is controlled by 
radio may be identified by the transmission of the call sign of the 
station at which communications originate.
    (2) One or more fixed relay stations may be identified by the 
transmission of the call signs of the stations at which the 
communications originate.
    (3) When a mobile station transmits on a different frequency than 
its associated base station, the assigned call sign of either the mobile 
station or the base station may be transmitted. Further, a single mobile 
unit in the licensee's authorized geographic area of operation may 
transmit station identification on behalf of any other operating mobile 
units in the fleet.
    (4) Use of an identifier other than the assigned call sign. (i) In 
the Public Safety Pool, mobile units licensed to a governmental entity 
and which operate on frequencies above 30 MHz may use an identifier 
which contains, at a minimum, the name of the licensee if the licensee 
maintains at the station a list of the special identifiers to be used by 
the mobile units.
    (ii) In the Industrial/Business Pool, licensees may request the 
Commission's Wireless Telecommunications Bureau to approve the use of 
special

[[Page 405]]

mobile unit identifiers in lieu of the assigned call sign. Such 
requests, however, will not be granted where it appears that harmful 
interference to international operations may be caused by stations below 
50 MHz, or by stations operating in areas within 80 km (50 miles) of an 
international boundary, or where it appears that the proposed method of 
identification will not adequately distinguish the mobile units of the 
applicant from the mobile units of other licensees in the area.
    (iii) In the Industrial/Business Pool, railroad licensees (as 
defined in Sec.  90.7) may identify stations by the name of the railroad 
and the train number, caboose number, engine number, or the name of the 
fixed wayside station. If none of these forms is practicable, any 
similar name or number may be designated by the railroad concerned for 
use by its employees in the identification of fixed points or mobile 
units, provided that a list of such identifiers is maintained by the 
railroad. An abbreviated name or the initials of the railroad may be 
used where such are in general usage. In those areas where it is shown 
that no difficulty would be encountered in identifying the transmission 
of a particular station (as, for example, where stations of one licensee 
are located in a yard isolated from other radio installations), approval 
may be given to a request from the licensee for permission to omit the 
station identification.
    (5) Use of identifiers in addition to assigned call signs. Nothing 
in this section shall be construed as prohibiting the transmission of 
station or unit identifiers which may be necessary or desirable for 
system operation, provided that they are transmitted in addition to the 
assigned station call sign or other permissible form of identification.
    (b) Use of automatic Morse code identification equipment. 
Automatically activated equipment may be used to transmit station 
identification in International Morse Code pursuant to the following 
conditions:
    (1) The signal output of the automatic identification equipment 
shall be connected to the transmitter at the microphone input or any 
other manufacturer-provided signal input terminal and shall be adjusted 
to produce 40 percent 10 percent of the maximum 
permissible modulation or deviation level. This adjustment shall be 
performed when all other modulating signals are absent.
    (2) The Morse code transmission rate shall be maintained between 20 
and 25 words per minute.
    (3) The frequency of the keyed tone comprising the identification 
signal shall be 1200 800 Hz. A licensee may be 
required to change the frequency in order to prevent interference to the 
operations of another co-channel licensee.
    (4) Should activation of automatic Morse code identification 
equipment interrupt the communications of another co-channel licensee, 
the Commission may require the use of equipment which will delay 
automatic station identification until such co-channel communications 
are completed.
    (c) Special provisions for identification in the Radiolocation 
Service. (1) Stations in the Radiolocation Service are not required to 
identify except upon special instructions from the Commission or as 
required by paragraphs (c)(2) and (3) of this section.
    (2) Stations in the Radiolocation Service operating on frequencies 
above 3400 kHz that employ spread spectrum techniques shall transmit a 
two letter manufacturer's designator, authorized by the Commission on 
the station authorization, at the beginning and ending of each 
transmission and once every 15 minutes during periods of continuing 
operation. The designator shall be transmitted in International Morse 
Code at a speed not exceeding 25 words per minute, and the spread 
spectrum mode of operation shall be maintained while the designator is 
being transmitted. The identifying signal shall be clearly receivable in 
the demodulated audio of a narrow-band FM receiver.
    (3) Oceanographic radars operating in the bands shown in section 
90.103(b) shall transmit a station identification (call sign) on the 
assigned frequency, in international Morse code at a transmission rate 
in accordance with paragraph (b)(2) of this section at the end of each 
data acquisition cycle, but at an interval of no more than 20 minutes.

[[Page 406]]

    (d) General exemptions. A station need not transmit identification 
if:
    (1) It is a mobile station operating on the transmitting frequency 
of the associated base station.
    (2) It is a mobile station in the Public Safety Pool using F1E or 
G1E emission.
    (3) It is transmitting for telemetering purposes or for the 
activation of devices which are employed solely as a means of attracting 
attention, or for remote control purposes, or which is retransmitting by 
self-actuating means, a radio signal received from another radio station 
or stations.
    (4) It is any type of radiopositioning or radar station authorized 
in a service other than the Radiolocation Service.
    (5) It is used solely for automatic vehicle monitoring or location.
    (6) It is a paging station authorized in accordance with the 
provisions of Sec.  90.20(a)(2)(v).
    (7) It is a mobile station employing non-voice emissions and the 
associated base station identifies on behalf of the mobile unit(s).
    (8) It is a base or mobile station in the 220-222 MHz band 
authorized to operate on a nationwide basis in accordance with subpart T 
of this part.
    (9) It is a wireless microphone station operating in accordance with 
the provisions of Sec.  90.265(b).
    (10) It is a Roadside Unit in a DSRCS system.
    (e) Special provisions for stations licensed under this part that 
are classified as CMRS providers under part 20 of this chapter.
    (1) Station identification will not be required for 929-930 MHz 
nationwide paging licensees or MTA or EA-based SMR licensees. All other 
CMRS stations will be required to comply with the station identification 
requirements of this paragraph.
    (2) CMRS stations subject to a station identification requirement 
will be permitted to use a single call sign for commonly owned 
facilities that are operated as part of a single system. The call sign 
must be transmitted each hour within five minutes of the hour, or upon 
completion of the first transmission after the hour.
    (3) CMRS stations granted exclusive channels may transmit their call 
signs digitally. A licensee that identifies its call sign in this manner 
must provide the Commission, upon request, information sufficient to 
decode the digital transmission and ascertain the call sign transmitted.
    (f) Special provisions for stations licensed under this part that 
are not classified as CMRS providers under part 20 of this chapter.
    (1) Stations subject to a station identification requirement will be 
permitted to use a single call sign for commonly owned facilities that 
are operated as part of a single system.
    (2) Stations licensed on an exclusive basis in the bands between 150 
and 512 MHz that normally employ digital signals for the transmission of 
data, text, control codes, or digitized voice may be identified by 
digital transmission of the call sign. A licensee that identifies its 
call sign in this manner must provide the Commission, upon request, 
information sufficient to decode the digital transmission and ascertain 
the call sign transmitted.

Sec.  90.427  Precautions against unauthorized operation.

    (a) Each transmitter shall be so installed and protected that it is 
not accessible to or capable of operation by persons other than those 
duly authorized by and under the control of the licensee. Provisions of 
this part authorizing certain unlicensed persons to operate stations, or 
authorizing unattended operation of stations in certain circumstances, 
shall not be construed to change or diminish in any respect the 
responsibility of station licensees to maintain control over the 
stations licensed to them (including all transmitter units thereof), or 
for the proper functioning and operation of those stations and 
transmitter units in accordance with the terms of the licenses of those 
stations.
    (b) Except for frequencies used in accordance with Sec.  90.417, no

                      Subpart O_Transmitter Control



Sec.  90.460  Scope.

    This subpart sets forth the provisions relating to permissible 
methods of transmitter control and interconnection (see the definition 
in Sec.  90.7) of radio systems authorized under this part.

[44 FR 67124, Nov. 23, 1979, as amended at 62 FR 18934, Apr. 17, 1997]



Sec.  90.461  Direct and remote control of transmitters.

    (a) In general. Radio transmitters may be operated and controlled 
directly (as when the operating position for the transmitter and the 
transmitter being operated are at the same location), or remotely (as 
when the transmitter being operated and the position from which it is 
being operated are at different locations).
    (b) Control of transmitters at remote locations. Radio transmitters 
at remote locations may be operated and controlled through the use of 
wire line or radio links; or through dial-up circuits, as provided in 
paragraph (c) of this section. Such control links or circuits may be 
either those of the licensee or they may be provided by common carriers 
authorized by law to furnish such service.
    (c) Dial-up circuits. Dial-up circuits may be provided by wire line 
telephone companies under appropriate tariffs, and they may be used by 
licensees for purposes of transmitter control, provided:
    (1) The dial-up circuits serve only to link licensed transmitter 
control points and the transmitters being controlled.
    (2) The dial-up circuits are so designed that the transmitters being 
controlled cannot be operated from any fixed position other than the 
licensed control points for those transmitters.
    (3) Equipment used to provide the transmitter/dial-up-circuit 
interface is designed to preclude associated mobile units of the 
licensee from reaching any point(s) served by the wire line telephone 
facilities other than the control point(s) of the station(s) controlled.
    (4) Any direct electrical connection to the telephone network shall 
comply with applicable tariffs and with part 68 of the Commission's 
Rules (See Sec.  90.5(j)).
    (5) Interconnection, within the meaning of Sec. Sec.  90.7 and 
90.477 through 90.483, may not take place at a control point which 
connects to its associated transmitter(s) through dial-up circuits; nor 
may such dial-up transmitter control circuits be used in conjunction 
with (or shared by) interconnection equipment.

[43 FR 54791, Nov. 22, 1978, as amended at 44 FR 67124, Nov. 23, 1979; 
60 FR 50123, Sept. 28, 1995]



Sec.  90.463  Transmitter control points.

    (a) A control operator is required to be stationed at the operating 
position of a transmitter control point. A control operator is any 
person designated by the licensee to exercise supervision and control 
over the operation and use of the licensee's facilities. The control 
operator may be the licensee; or an employee of the licensee; or the 
agent of the licensee, appointed by the licensee to act as the control 
operator; or a third-party contractor, engaged by the licensee to serve 
as the control operator: Provided, however, In no case, through 
appointment or designation of any person to serve as control operator, 
may the licensee delegate any of the duties and responsibilities the 
licensee may have in his capacity as licensee.
    (b) Each station or licensed system of communication shall normally 
have a control point, or control points, at which the control operator 
or operators are stationed and at or from which the licensee may 
exercise supervision and control over the authorized facilities, as 
required by the provisions of Sec.  90.461. Provided, however, Control 
point requirements may vary from one system to another, depending upon 
the nature of the radio operation; the way

[[Page 410]]

and by whom the facilities are employed; and other factors, as set out 
in other rule sections under this subpart.
    (c) A transmitter control point may be located at a fixed position 
in a system of communication at or from which the control operator 
exercises supervision and control over the operation and use of the 
licensed facilities. Each fixed transmitter control point shall have 
equipment and facilities to permit the control operator:
    (1) To determine when the transmitter or transmitters controlled are 
either radiating ``RF'' energy, or when the transmitter circuits have 
been placed in a condition to produce such radiation. This may be 
accomplished either through the use of a carrier operated device which 
provides a visual indication when the transmitter(s) are radiating or a 
pilot lamp or meter which provides a visual indication when the 
transmitter circuits have been placed in a condition to produce 
radiation. Further, where a local transmitter is used to activate a 
remote transmitter or transmitters in the licensee's system of 
communication, a single pilot lamp or meter may be employed to indicate 
the activation of both the local and the remote transmitter(s).
    (2) To turn the carrier of the transmitter on and off at will, or to 
close the system down completely, when circumstances warrant such 
action.
    (d) The licensee's transmitting facilities may be operated from 
dispatch points, the fixed control point shall have equipment to permit 
the control operator to either disconnect the dispatch point circuits 
from the transmitter(s) or to render the transmitter(s) inoperative from 
any dispatch point being supervised.
    (e) Where the system is interconnected with public communication 
facilities, as provided at Sec. Sec.  90.477 through 90.483, and where 
those rules so require, the fixed control point shall be equipped to 
permit the control operator:
    (1) To monitor co-channel facilities of other licensees sharing an 
assigned channel or channels with the licensee in the licensee's area of 
operation; and,
    (2) To terminate any transmission(s) or communication(s) between 
points in the public communications system and the private 
communications system.
    (f) In urban areas, the location of fixed transmitter control points 
will be specified, ``same as transmitter,'' unless the control point is 
at a street address which is different from that of the transmitter(s) 
controlled. In rural areas, the location of fixed control points will be 
specified, ``same as transmitter,'' unless the control point is more 
than 152.5 m (500 ft) from the transmitter(s) controlled. In the latter 
case, the approximate location of the control point will be specified in 
distance and direction from the transmitter(s) controlled in terms of 
distance and geographical quadrant, respectively. It would be assumed 
that the location of a fixed control point is the same as the location 
of the transmitter(s) controlled, unless the applicant includes a 
request for a different location described in appropriate terms as 
indicated herein.
    (g) [Reserved]
    (h) Mobile transmitters shall be assumed to be under the immediate 
control of the mobile operator; provided, however, overall supervision 
and control of the operation and use of a communication system may be 
the responsibility of a fixed control point operator. In general, mobile 
transmitters shall be equipped to permit the operator to determine when 
they are radiating ``RF'' energy or when the transmitter circuits have 
been placed in a condition to produce such radiation. This may be 
accomplished either through the use of a carrier operated device or of a 
pilot lamp or meter which will provide a visual indication when the 
transmitter is radiating or has been placed in a condition to produce 
radiation provided, however, that hand-carried or pack-carried 
transmitters and transmitters installed on motorcycles need not be so 
equipped.

[[Page 411]]



Sec.  90.465  Control of systems of communication.

    (a) Depending on design considerations, control of a system of 
communication may be exercised in varying ways. In single frequency 
simplex, base/mobile operations, control may be exercised by the control 
operator at the fixed control point. In mobile relay systems, where 
there is an associated control point or control station, control may be 
exercised by the operator at the control point or control station. In 
mobile-only systems, control may be exercised by the mobile operator. In 
communication systems involving multiple base stations or fixed relays 
control of the system may result from a combination of factors and 
considerations, including control by a fixed control point operator at 
some point within the system of communication or control by the mobile 
station operator of the licensee.
    (b) In internal systems, as defined in Sec.  90.7, control may be 
maintained by conforming the system to the requirements of Sec. Sec.  
90.471 through 90.475.
    (c) In interconnected systems, as defined in Sec.  90.7, control may 
be maintained by conforming operation and system design to that 
permitted in Sec. Sec.  90.477 through 90.483.

[43 FR 54791, Nov. 22, 1978, as amended at 54 FR 39740, Sept. 28, 1989; 
72 FR 35199, June 27, 2007]



Sec.  90.467  Dispatch points.

    Dispatch points meeting the requirements of this section need not be 
specifically authorized; provided, however, that the licensee of any 
radio station operated from a dispatch point or points shall assume full 
responsibility for the use and operation of the authorized facilities in 
compliance with all applicable provisions of law or rule and shall 
comply with the policy:
    (a) A dispatch point may be linked to the transmitter(s) being 
operated by private or leased wire line of fixed radio circuits, 
provided the requirements of Sec.  90.463 are met.
    (b) No telephone position in the public, switched, telephone network 
will be treated as a dispatch point within the meaning or intent of this 
section.
    (c) Operation of transmitting facilities from dispatch points is 
permitted only when the control operator at a fixed control point in the 
system is on duty and at no other time.



Sec.  90.469  Unattended operation.

    (a) Subject to the provisions of Sec. Sec.  90.243, 90.245, and 
90.247, mobile relay, fixed relay, and mobile repeater stations are 
authorized for unattended operation; and the transmitter control point 
requirements set out at Sec. Sec.  90.463 through 90.465 shall not 
apply.
    (b) Self-activated transmitters may be authorized for unattended 
operation where they are activated by either electrical or mechanical 
devices, provided the licensee adopts reasonable means to guard against 
malfunctions and harmful interference to other users.

                  Internal Transmitter Control Systems



Sec.  90.471  Points of operation in internal transmitter control systems.

    The transmitting facilities of the licensee may be operated from 
fixed positions located on premises controlled by the licensee. The 
fixed position may be part of a private telephone exchange or it may be 
any position in a closed or limited access communications facility 
intended to be used by employees of the licensee for internal 
communications and transmitter control purposes. Operating positions in 
internal transmitter control systems are not synonymous with dispatch 
points (See Sec.  90.467) nor with telephone positions which are part of 
the public, switched telephone network; and the scheme of regulation is 
to be considered and treated as being different. See Sec. Sec.  90.485 
through 90.489.

[44 FR 67125, Nov. 23, 1979]



Sec.  90.473  Operation of internal transmitter control systems 
through licensed fixed control points.

    An internal transmitter control system may be operated under the 
control and supervision of a control operator stationed at a fixed 
control point in the system. In such a case, the control point must be 
equipped to permit the control operator to monitor all traffic to and 
from fixed positions and mobile stations or paging units of the 
licensee; and the system shall be so designed to

[[Page 412]]

permit the control operator to either disconnect any operating position 
in the internal system from the transmitter control circuit or to close 
the system down entirely at will.

[44 FR 67125, Nov. 23, 1979]



Sec.  90.475  Operation of internal transmitter control systems 
in specially equipped systems.

    (a) An internal transmitter control system need not be designed to 
meet the requirements of Sec.  90.473 if it meets the following 
requirements:
    (1) All operating positions must be located on premises controlled 
by the licensee.
    (2) An internal transmitter control system may be used in 
conjunction with other approved methods of transmitter control and 
interconnection so long as the internal transmitter control system, 
itself, is neither accessed from telephone positions in the public 
switched telephone network (PSTN), nor uses dial-up circuits in the 
PSTN. Licensees with complex communications systems involving fixed 
systems whose base stations are controlled by such systems may 
automatically access these base stations through the microwave or 
operational fixed systems from positions in the PSTN, so long as the 
base stations and mobile units meet the requirements of Sec.  90.483 and 
if a separate circuit is provided for each mode of transmitter operation 
(i.e., conventional, dial-up or Internet).
    (3) The system must be designed so that upon completion of a 
transmission, the base station transmitter(s) will close down 
automatically within 3 seconds.
    (4) To guard against malfunctions, the system must also be designed 
so that the base station(s) will be deactivated by an automatic timing 
device when a modulated signal is not transmitted for a period of three 
(3) consecutive minutes.
    (5) The system must include automatic monitoring equipment, 
installed at the base station transmitter site(s), which will prevent 
the activation of the system when signals of other co-channel stations 
are present.
    (b) [Reserved]

Sec.  90.477  Interconnected systems.

    (a) Applicants for new land stations to be interconnected with the 
public switched telephone network must indicate on their applications 
(class of station code) that their stations will be interconnected. 
Licensees of land stations that are not interconnected may interconnect 
their stations with the public switched telephone network only after 
modifying their license. See Sec.  1.929 of this chapter. In all cases a 
detailed description of how interconnection is accomplished must be 
maintained by licensees as part of their station records. See Sec.  
90.433 of this part.
    (b) In the frequency ranges 806-824 MHz, 851-869 MHz, 896-901 MHz, 
and 935-940 MHz, interconnection with the public switched telephone 
network is authorized under the following conditions:
    (1) Interconnected operation is on a secondary basis to dispatch 
operation.

[[Page 413]]

This restriction will not apply to trunked systems or on any channel 
assigned exclusively to one licensee.
    (2) Interconnection may be accomplished at any location through a 
separate or shared interconnection device. When land stations subject to 
this part are multiple licensed or shared by authorized users, 
arrangements for telephone service must be made with a duly authorized 
carrier by users, licensees, or their authorized agents on a non-profit 
cost sharing basis. When telephone service costs are shared, at least 
one licensee participating in the cost sharing arrangement must maintain 
cost sharing records and the costs must be distributed at least once a 
year. Licensees, users, or their authorized agents may also make joint 
use arrangements with a duly authorized carrier and arrange that each 
licensee or user pay the carrier directly for the licensee's or user's 
share of the joint use of the shared telephone service. A report of the 
cost distribution must be placed in the licensee's station records and 
made available to participants in the sharing and the Commission upon 
request. In all cases, arrangements with the duly authorized carrier 
must disclose the number of licensees and users and the nature of the 
use.
    (c) Interconnection of facilities in the Radiolocation Service 
(subpart F) will not be permitted.
    (d) In the frequency ranges below 800 MHz, interconnection with the 
public switched telephone network is authorized under the following 
conditions:
    (1) Interconnected operation is on a secondary basis to dispatch 
operation. This restriction will not apply to trunked systems or on any 
channel assigned exclusively to one licensee.
    (2) Interconnection may be accomplished at any location through a 
separate or shared interconnection device. When land stations subject to 
this part are multiple licensed or shared by authorized users, 
arrangements for telephone service must be made with a duly authorized 
carrier by users, licensees, or their authorized agents on a non-profit 
cost sharing basis. When telephone service costs are shared, at least 
one licensee participating in the cost sharing arrangement must maintain 
cost sharing records and the costs must be distributed at least once a 
year. Licensees, users, or their authorized agents may also make joint 
use arrangements with a duly authorized carrier and arrange that each 
licensee or user pay the carrier directly for the licensee's or user's 
share of the joint use of the shared telephone service. A report of the 
cost distribution must be placed in the licensee's station records and 
made available to participants in the sharing and the Commission upon 
request. In all cases, arrangements with the duly authorized carrier 
must disclose the number of licensees and users and the nature of the 
use.
    (3) For licensees in the Industrial/Business Pool and those 
licensees who establish eligibility pursuant to Sec.  90.20(a)(2) of 
this part, except for Sec. Sec.  90.20(a)(2)(i) and 90.20(a)(2)(ii) of 
this part and medical emergency systems in the 450-470 MHz band, 
interconnection will be permitted only where the base station site or 
sites proposed stations are located 120 km (75 mi.) or more from the 
designated centers of the urbanized areas listed below. If these 
licensees seek to connect within 120 km (75 mi.) of the 25 cities, they 
must obtain the consent of all co-channel licensees located both within 
120 km (75 mi.) of the center of the city; and within 120 km (75 mi.) of 
the interconnected base station transmitter. The consensual agreements 
among the co-channel licensees must specifically state the terms agreed 
upon and a statement must be submitted to the Commission indicating that 
all co-channel licensees have consented to the use of interconnection. 
If a licensee has agreed to the use of interconnection on the channel, 
but later decides against the use of interconnection, the licensee may 
request that the co-channel licensees reconsider the use of 
interconnection. If the licensee is unable to reach an agreement with 
co-channel licensees, the licensee may request that the Commission 
consider the matter and assign it to another channel. If a new licensee 
is assigned to a frequency where all the co-channel licensees have 
agreed to the use of interconnection and the new licensee does not 
agree, the new licensee may request that the co-channel licensees 
reconsider the use of interconnection. If the new licensee cannot

[[Page 414]]

reach an agreement with co-channel licensees it may request that the 
Commission reassign it to another channel.

Sec.  90.483  Permissible methods and requirements of interconnecting private 
and public systems of communications.

    Interconnection may be accomplished by commercial mobile service 
providers licensed under this part by any technically feasible means. 
Interconnection may be accomplished by private mobile service providers 
either manually or automatically under the supervision and control of a 
transmitter control operator at a fixed position in the authorized 
system of communications or it may be accomplished under the supervision 
and control of mobile operators, and is subject to the following 
provisions:
    (a) Where a system is interconnected manually at a fixed control 
point, the control point operator must maintain the capability to turn 
the carrier of the transmitter off or to de-activate the system 
completely when circumstances warrant such action.
    (b) When the system is interconnected automatically it may be 
supervised at the control point or in mobile units.
    (1) For control point supervision, the following is required:
    (i) The control point operator must maintain the capability to turn 
the carrier of the transmitter off or to de-activate the system 
completely when circumstances warrant such action.
    (ii) When a frequency is shared by more than one system, automatic 
monitoring equipment must be installed at the base station to prevent 
activation of the transmitter when signals of co-channel stations are 
present and activation would interfere with communications in progress. 
Licensees may operate without the monitoring equipment if they have 
obtained the consent of all co-channel licensees located within a 120 
kilometer (75 mile) radius of the interconnected base station 
transmitter. A statement must be submitted to the Commission indicating 
that all co-channel licensees have consented to operate without the 
monitoring equipment. If a licensee has agreed that the use of 
monitoring equipment is not necessary, but later decides that the 
monitoring equipment is necessary, the licensee may request that the co-
channel licensees reconsider the use of monitoring equipment. If the 
licensee cannot reach an agreement with co-channel licensees, the 
licensee may request that the Commission consider the matter and assign 
it to another channel. If a new licensee is assigned to a frequency 
where all the co-channel licensees have agreed that the use of 
monitoring equipment is not necessary, and the new licensee does

[[Page 415]]

not agree, the new licensee may request the co-channel licensees to 
reconsider the use of monitoring equipment. If the new licensee cannot 
reach an agreement with co-channel licensees, it should request a new 
channel from the Commission. Systems on frequencies above 800 MHz are 
exempt from this requirement.
    (2) For mobile unit supervision, the following is required:
    (i) When a frequency is shared by more than one system, automatic 
monitoring equipment must be installed at the base station to prevent 
activation of the transmitter when signals of co-channel stations are 
present and activation would interfere with communications in progress. 
Licensees may operate without this equipment if they have obtained the 
consent of all co-channel licensees located within a 120 kilometer (75 
mile) radius of the interconnected base station transmitter. A statement 
must be submitted to the Commission indicating that all co-channel 
licensees have consented to operate without the monitoring equipment. If 
a licensee has agreed that the use of monitoring equipment is not 
necessary, but later decides that the monitoring equipment is necessary, 
the licensee may request that the co-channel licensees reconsider the 
use of monitoring equipment. If the licensee cannot reach an agreement 
with co-channel licensees, the licensee may request that the Commission 
consider the matter and assign it to another channel. If a new licensee 
is assigned to a frequency where all the co-channel licensees have 
agreed that the use of monitoring equipment is not necessary, and the 
new licensee does not agree, the new licensee may request the co-channel 
licensees to reconsider the use of monitoring equipment. If the new 
licensee cannot reach an agreement with co-channel licensees, it should 
request a new channel from the Commission. Systems on frequencies above 
800 MHz are exempt from this requirement.
    (ii) Initial access points within the public switched telephone 
network must be limited to transmission of a 3-second tone, after which 
time the transmitter shall close down. No additional signals may be 
transmitted until acknowledgement from a mobile station of the licensee 
is received. Licensees are exempt from this requirement if they have 
obtained the consent of all co-channel licensees located within a 120 
kilometer (75 mile) radius of the interconnected base station 
transmitter. However, licensees may choose to set their own time 
limitations. A statement must be submitted to the Commission indicating 
that all co-channel licensees have consented to operate without the 
monitoring equipment. If a licensee has agreed that the use of 
monitoring equipment is not necessary, but later decides that the 
monitoring equipment is necessary, the licensee may request that the co-
channel licensees reconsider the use of monitoring equipment. If the 
licensee cannot reach an agreement with co-channel licensees, the 
licensee may request that the Commission consider the matter and assign 
it to another channel. If a new licensee is assigned to a frequency 
where all the co-channel licensees have agreed that the use of 
monitoring equipment is not necessary, and the new licensee does not 
agree, the new licensee may request the co-channel licensees to 
reconsider the use of monitoring equipment. If the new licensee cannot 
reach an agreement with co-channel licensees, it should request a new 
channel from the Commission. Systems on frequencies above 800 MHz are 
exempt from this requirement.
    (c) In single frequency systems, equipment must be installed at the 
base station which will limit any single transmission from within the 
public switched telephone network to 30 seconds duration and which in 
turn will activate the base station receiver to monitor the frequency 
for a period of not less than three (3) seconds. The mobile station must 
be capable of terminating the communications during the three (3) 
seconds. Licensees are exempt from this requirement if they have 
obtained the consent of all co-channel licensees located within a 120 km 
(75 mile) radius of the interconnected base station transmitter. 
However, licensees may choose to set their own time limitations. A 
statement must be submitted to the Commission indicating that all co-
channel licensees have consented to operate without the monitoring 
equipment. If a licensee has

[[Page 416]]

agreed that the use of monitoring equipment is not necessary, but later 
decides that the monitoring equipment is necessary, the licensee may 
request that the co-channel licensees reconsider the use of monitoring 
equipment. If the licensee cannot reach an agreement with co-channel 
licensees, the licensee may request that the Commission consider the 
matter and assign it another channel. If a new licensee is assigned to a 
frequency where all the co-channel licensees have agreed that the use of 
monitoring equipment. If the new licensee cannot reach an agreement with 
co-channel licensees, it should request a new channel from the 
Commission.
    (d) A timer must be installed at the base station transmitter which 
limits communications to three (3) minutes. After three (3) minutes, the 
system must close down, with all circuits between the base station and 
the public switch telephone network disconnected. This provision does 
not apply to systems which establish eligibility pursuant to Sec. Sec.  
90.20(a)(1)(i), 90.20(a)(1)(ii), and 90.20(a)(2), except Sec. Sec.  
90.20(a)(2)(i) and 90.20(a)(2)(ii), or who are Power, Petroleum, or 
Railroad licensees (as defined in Sec.  90.7), or to systems above 800 
MHz. All systems must be equipped with a timer that closes down the 
transmitter within three minutes of the last transmission. Licensees may 
operate without these requirements if they have obtained the consent of 
all co-channel licensees located within a 120 km (75 mile) radius of the 
interconnected base station transmitter. However, licensees may choose 
to set their own time limitations. A statement must be submitted to the 
Commission indicating that all co-channel licensees have consented to 
operate without the monitoring equipment. If a licensee has agreed that 
the use of monitoring equipment is not necessary, but later decides that 
the monitoring equipment is necessary, the licensee may request that the 
co-channel licensees reconsider the use of monitoring equipment. If the 
licensee cannot reach an agreement with co-channel licensees, the 
licensee may request that the Commission consider the matter and assign 
it to another channel. If a new licensee is assigned to a frequency 
where all the co-channel licensees have agreed that the use of 
monitoring equipment is not necessary, and the new licensee does not 
agree, the new licensee may request the co-channel licensees to 
reconsider the use of monitoring equipment. If the new licensee cannot 
reach an agreement with co-channel licensees, it should request a new 
channel from the Commission.

                       Subpart P_Paging Operations



Sec.  90.490  One-way paging operations in the private services.

    (a) Subject to specific prohibition or restriction by rule 
provisions governing the radio service in which a licensee's radio 
system is authorized, paging operations are permitted:
    (1) Where the signals and messages are transmitted by a control 
operator of the licensee stationed at a licensed control point in the 
licensee's system of communication.
    (2) Where the signals and messages are transmitted from an operating 
position within an internal system of communication which meets the 
tests of Sec. Sec.  90.471 through 90.475.
    (3) Where the signals and messages are transmitted from a dispatch 
point within the licensee's system of communication, as defined as Sec.  
90.7.
    (b) Systems employing dial-up circuits (Sec.  90.461(c)) may be used 
in one-way paging operations, but only where the paging signals are 
transmitted as provided at paragraph (a)(1) of this section.
    (c) Paging may be initiated directly from telephone positions in the 
public switched telephone network. When land stations are multiple 
licensed or otherwise shared by authorized users, arrangements for the 
telephone service must be made with a duly authorized carrier by users, 
licensees, or their authorized agents on a non-profit, cost-shared 
basis. When telephone service costs are shared, at least one licensee

[[Page 417]]

participating in the cost sharing arrangements must maintain cost 
sharing records and the costs must be distributed at least once a year. 
Licensees, users, or their authorized agents may also make joint use 
arrangements with a duly authorized carrier and arrange that each 
licensee or user pay the carrier directly for the licensee's or user's 
share of the joint use of the shared telephone service. A report of the 
cost distribution must be placed in the licensee's station records and 
made available to participants in the sharing arrangement and the 
Commission upon request. In all cases, arrangements with the duly 
authorized carrier must disclose the number of licensees and users and 
the nature of the use.

Sec.  90.525  Administration of interoperability channels.

    (a) States are responsible for administration of the 
Interoperability channels in the 769-775 MHz and 799-805 MHz frequency 
bands. Base and control stations must be licensed individually. A public 
safety entity meeting the requirements of Sec.  90.523 may operate 
mobile or portable units on the Interoperability channels in the 769-775 
MHz and 799-805 MHz frequency bands without a specific authorization 
from the Commission provided it holds a part 90 license. All persons 
operating mobile or portable units under this authority are responsible 
for compliance with part 90 of these rules and other applicable federal 
laws.
    (b) License applications for Interoperability channels in the 769-
775 MHz and 799-805 MHz frequency bands must be approved by a state-
level agency or organization responsible for administering state 
emergency communications. States may hold the licenses for 
Interoperability channels or approve other qualified entities to hold 
such licenses. States may delegate the approval process for 
interoperability channels to another entity, such as regional planning 
committees.

Sec.  90.527  Regional plan requirements.

    Each regional planning committee must submit a regional plan for 
approval by the Commission.
    (a) Common elements. Regional plans must incorporate the following 
common elements:
    (1) Identification of the document as the regional plan for the 
defined region with the names, business addresses, business telephone 
numbers, and organizational affiliations of the chairpersons and all 
members of the planning committee.
    (2) A summary of the major elements of the plan and an explanation 
of how all eligible entities within the region were given an opportunity 
to participate in the planning process and to have their positions heard 
and considered fairly.
    (3) A general description of how the spectrum would be allotted 
among the various eligible users within the region with an explanation 
of how the requirements of all eligible entities within the region were 
considered and, to the degree possible, met.
    (4) An explanation as to how needs were assigned priorities in areas 
where not all eligible entities could receive licenses.
    (5) An explanation of how the plan had been coordinated with 
adjacent regions.
    (6) A detailed description of how the plan put the spectrum to the 
best possible use by requiring system design with minimum coverage 
areas, by assigning frequencies so that maximum frequency reuse and 
offset channel use may be made, by using trunking, and by requiring 
small entities with minimal requirements to join together in using a 
single system where possible.
    (7) A detailed description of the future planning process, 
including, but not limited to, amendment process, meeting announcements, 
data base maintenance, and dispute resolution.
    (8) A certification by the regional planning chairperson that all 
planning committee meetings, including subcommittee or executive 
committee meetings, were open to the public.
    (b) Modification of regional plans. Regional plans may be modified 
by submitting a written request, signed by the regional planning 
committee, to the Chief, Public Safety and Homeland Security Bureau. The 
request must contain the full text of the modification. Modifications 
are considered either major or minor. Regional planning committees must 
certify that successful coordination with all adjacent regions has 
occurred for major modifications and that all such regions concur with 
the major modification. Unless requested otherwise by the regional 
planning committee, the Bureau will only place major modifications on 
public notice for comment.
    (1) Except as noted below, modifications changing the way channels 
are allocated, allotted or coordinated are considered major 
modifications.

[[Page 420]]

    (2) Modifications changing how channels are allotted are considered 
minor modifications only if:
    (i) The proposed channel change or channel addition involves a 
facility located more than seventy miles from the adjacent region 
border;
    (ii) The co-channel or adjacent channel interference contour of the 
facility changing or adding the channel does not intersect the border of 
an adjacent region, or
    (iii) The proposed channel change or channel addition has been 
coordinated in writing with any affected adjacent region.
    (3) Changes in membership or leadership of regional planning 
committees are considered minor modifications.

Sec.  90.529  State License.

    (a) Narrowband channels designated as state channels in Sec.  90.531 
are licensed to each state (as defined in Sec.  90.7) as follows:
    (1) Each state that chooses to take advantage of the spectrum 
designated as state channels must file an application for up to 2.4 
megahertz of this spectrum no later than December 31, 2001. For purposes 
of this section, the elected chief executive (Governor) of each state, 
or his or her designee, shall be deemed the person authorized to apply 
for the State License.
    (2) What ever part of this 2.4 megahertz that a state has not 
applied for by December 31, 2001, will revert to General Use and be 
administered by the relevant RPC (or RPCs in the instances of states 
that encompass multiple RPCs).
    (b) Each state license will be granted subject to the condition that 
the state certifies on or before each applicable benchmark date that it 
is:
    (1) Providing or prepared to provide ``substantial service'' to one-
third of their population or territory by June 13, 2014, i.e., within 
five years of the date that incumbent broadcasters are required to 
relocate to other portions of the spectrum;
    (2) Providing or prepared to provide ``substantial service'' to two-
thirds of their population or territory by June 13, 2019, i.e., within 
ten years of the date that incumbent broadcasters are required to 
relocate to other portions of the spectrum.
    (c) The Commission will deem a state ``prepared to provide 
substantial service'' if the licensee certifies that a radio system has 
been approved and funded for implementation by the deadline date. 
``Substantial service'' refers to the construction and operation of 700 
MHz facilities by public safety entities providing service which is 
sound, favorable , and substantially above a level of mediocre service 
which just might minimally warrant renewal.
    (d) If a state licensee fails to meet any condition of the grant the 
state license is modified automatically to the frequencies and 
geographic areas where the state certifies that it is providing 
substantial service.
    (e) Any recovered state license spectrum will revert to General Use. 
However, spectrum licensed to a state under a state license remains 
unavailable for reassignment to other applicants until the Commission's 
database reflects the parameters of the modified state license.

Sec.  90.537  Trunking requirement.

    (a) General use and State License channels. All fixed transmitter 
sites using six or more narrowband channels in the 769-775 MHz and 799-
805 MHz frequency bands must be trunked, except for those described in 
paragraph (b) of this section. This paragraph does not apply to 
Vehicular Repeater Systems (MO3) authorized on the General Use and State 
License channels listed in Sec.  90.531(b).
    (b) Interoperability and low power channels. Trunking is permitted 
only on Interoperability channels specified in Sec.  90.531(b)(1)(iii). 
Trunked use must be strictly on a secondary, non-interference basis to 
conventional operations. The licensee must monitor and immediately 
release these channels when they are needed for interoperability 
purposes. All systems using narrowband low power channels listed in 
Sec.  90.531(b)(3) and (4) are exempt from the trunking requirements 
described in paragraph (a) of this section.

section.
    (a) Mobile, portable and control transmitters must normally use 
automatic frequency control (AFC) to lock on to the base station signal.
    (b) The frequency stability of base transmitters operating in the 
narrowband segment must be 100 parts per billion or better.
    (c) The frequency stability of mobile, portable, and control 
transmitters operating in the narrowband segment must be 400 parts per 
billion or better when AFC is locked to the base station. When AFC is 
not locked to the base station, the frequency stability must be at least 
1.0 ppm for 6.25 kHz, 1.5 ppm for 12.5 kHz (2 channel aggregate), and 
2.5 ppm for 25 kHz (4 channel aggregate).
    (d) The frequency stability of base transmitters operating in the 
wideband segment must be 1 part per million or better.
    (e) The frequency stability of mobile, portable and control 
transmitters operating in the wideband segment must be 1.25 parts per 
million or better when AFC is locked to a base station, and 5 parts per 
million or better when AFC is not locked.

  band when measured at either the transmitting antenna input port or
  the output of the transmitter combining network. Consequently,
  licensees deploying these transmitters may need to use external
  filters to comply with the more restrictive ACP limit.

    (b) ACP measurement procedure. The following are the procedures for 
making the transmitter ACP measurements. For all measurements modulate 
the transmitter as it would be modulated in normal operating conditions. 
For time division multiple access (TDMA) systems, the measurements are 
to be made under TDMA operation only during time slots when the 
transmitter is active. All measurements are made at the transmitter's 
output port. If a transmitter has an integral antenna, a suitable power 
coupling device shall be used to couple the RF signal to the measurement 
instrument. The coupling device shall substantially maintain the proper 
transmitter load impedance. The ACP measurements may be made with a 
spectrum analyzer capable of making direct ACP measurements. 
``Measurement bandwidth'', as used for non-swept measurements, implies 
an instrument that measures the power in many narrow bandwidths

[[Page 428]]

equal to the nominal resolution bandwidth and integrates these powers to 
determine the total power in the specified measurement bandwidth.
    (1) Setting reference level. Set transmitter to maximum output 
power. Using a spectrum analyzer capable of ACP measurements, set the 
measurement bandwidth to the channel size. For example, for a 6.25 kHz 
transmitter set the measurement bandwidth to 6.25 kHz. Set the frequency 
offset of the measurement bandwidth to zero and adjust the center 
frequency of the instrument to the assigned center frequency to measure 
the average power level of the transmitter. Record this power level in 
dBm as the ``reference power level.''
    (2) Non-swept power measurement. Using a spectrum analyzer capable 
of ACP measurements, set the mesurement bandwidth and frequency offset 
from the assigned center frequency as shown in the tables in Sec.  
90.543 (a) above. Any value of resolution bandwidth may be used as long 
as it does not exceed 2 percent of the specified measurement bandwidth. 
Measure the power level in dBm. These measurements should be made at 
maximum power. Calculate ACP by substracting the reference power level 
measured in (b)(1) from the measurements made in this step. The absolute 
value of the calculated ACP must be greater than or equal to the 
absolute value of the ACP given in the table for each condition above.
    (3) Swept power measurement. Set a spectrum analyzer to 30 kHz 
resolution bandwidth, 1 MHz video bandwidth and average, sample, or RMS 
detection. Set the reference level of the spectrum analyzer to the RMS 
value of the transmitter power. Sweep above and below the carrier 
frequency to the limits defined in the tables. Calculate ACP by 
substracting the reference power level measured in (b)(1) from the 
measurements made in this step. The absolute value of the calculated ACP 
must be greater than or equal to the absolute value of the ACP given in 
the table for each condition above.
    (c) Out-of-band emission limit. On any frequency outside of the 
frequency ranges covered by the ACP tables in this section, the power of 
any emission must be reduced below the mean output power (P) by at least 
43 + 10log (P) dB measured in a 100 kHz bandwidth for frequencies less 
than 1 GHz, and in a 1 MHz bandwidth for frequencies greater than 1 GHz.
    (d) Authorized bandwidth. Provided that the ACP requirements of this 
section are met, applicants may request any authorized bandwidth that 
does not exceed the channel size.
    (e) For operations in the 758-768 MHz and the 788-798 MHz bands, the 
power of any emission outside the licensee's frequency band(s) of 
operation shall be attenuated below the transmitter power (P) within the 
licensed band(s) of operation, measured in watts, in accordance with the 
following:
    (1) On all frequencies between 769-775 MHz and 799-805 MHz, by a 
factor not less than 76 + 10 log (P) dB in a 6.25 kHz band segment, for 
base and fixed stations.
    (2) On all frequencies between 769-775 MHz and 799-805 MHz, by a 
factor not less than 65 + 10 log (P) dB in a 6.25 kHz band segment, for 
mobile and portable stations.
    (3) On any frequency between 775-788 MHz, above 805 MHz, and below 
758 MHz, by at least 43 + 10 log (P) dB.
    (4) Compliance with the provisions of paragraphs (e)(1) and (2) of 
this section is based on the use of measurement instrumentation such 
that the reading taken with any resolution bandwidth setting should be 
adjusted to indicate spectral energy in a 6.25 kHz segment.
    (5) Compliance with the provisions of paragraph (e)(3) of this 
section is based on the use of measurement instrumentation employing a 
resolution bandwidth of 100 kHz or greater. However, in the 100 kHz 
bands immediately outside and adjacent to the frequency block, a 
resolution bandwidth of 30 kHz may be employed.
    (f) For operations in the 758-775 MHz and 788-805 MHz bands, all 
emissions including harmonics in the band 1559-1610 MHz shall be limited 
to -70 dBW/MHz equivalent isotropically radiated power (EIRP) for 
wideband signals, and -80 dBW EIRP for discrete emissions of less than 
700 Hz bandwidth. For the purpose of equipment authorization, a 
transmitter shall be tested with an antenna that is representative of 
the type

[[Page 429]]

that will be used with the equipment in normal operation.
    (g) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.

    (c) Transceivers capable of operating on the narrowband 
Interoperability channels listed in Sec.  90.531(b)(1) shall not be 
marketed or sold unless the transceiver has previously been certified 
for interoperability by the Compliance Assessment Program (CAP) 
administered by the U.S. Department of Homeland Security; provided, 
however, that this requirement is suspended if the CAP is discontinued. 
Submission of a 700 MHz narrowband radio for certification will 
constitute a representation by the manufacturer that the radio will be 
shown, by testing, to be interoperable across vendors before it is 
marketed or sold. In the alternative, manufacturers may employ their own 
protocol for verifying compliance with Project 25 standards and 
determining that their product is interoperable among vendors. In the 
event that field experience reveals that a transceiver is not 
interoperable, the Commission may require the manufacturer thereof to 
provide evidence of compliance with this section.

Sec.  90.555  Information exchange.

    (a) Prior notification. Public safety licensees authorized to 
operate in the 758-775 MHz and 788-805 MHz bands may notify any licensee 
authorized to operate in the 746-757 MHz or 776-787 MHz bands that they 
wish to receive prior notification of the activation or modification of 
the licensee's base or fixed stations in their area. Thereafter, the 
746-757 MHz or 776-787 MHz band licensee must provide the following 
information to the public safety licensee at least 10 business days 
before a new base or fixed station is activated or an existing base or 
fixed station is modified:
    (1) Location;

[[Page 432]]

    (2) Effective radiated power;
    (3) Antenna height; and
    (4) Channels available for use.
    (b) Purpose of prior notification. The prior coordination of base or 
fixed stations is for informational purposes only. Public safety 
licensees are not afforded the right to accept or reject the activation 
of a proposed base or fixed station or to unilaterally require changes 
in its operating parameters. The principal purposes of notification are 
to:
    (1) Allow a public safety licensee to advise the 746-757 or 776-787 
MHz band licensee whether it believes a proposed base or fixed station 
will generate unacceptable interference;
    (2) Permit 746-757 and 776-787 MHz band licensees to make voluntary 
changes in base or fixed station parameters when a public safety 
licensee alerts them to possible interference; and,
    (3) Rapidly identify the source if interference is encountered when 
the base or fixed station is activated.
    (c) Public Safety Information Exchange. (1) Upon request by a 746-
757 or 776-787 MHz band licensee, public safety licensees authorized to 
operate radio systems in the 758-775 and 788-805 MHz bands shall provide 
the operating parameters of their radio system to the 746-757 or 776-787 
MHz band licensee.
    (2) Public safety licensees who perform the information exchange 
described in this section must notify the appropriate 746-757 or 776-787 
MHz band licensees prior to any technical changes to their radio system.

Sec.  90.557  Secondary fixed signaling operations.

    Trunked and conventional 700 MHz narrowband systems may conduct 
fixed ancillary signaling and data transmissions subject to the 
following requirements:
    (a) Operations are permitted only on:
    (1) Narrowband State License channels specified in Sec.  
90.531(b)(5), subject to the discretion of the relevant State licensee; 
and
    (2) Narrowband General Use channels specified in Sec.  90.531(b)(6), 
subject to the discretion of the regional planning committee.
    (b) All operations must be on a secondary, non-interference basis to 
the primary mobile operation of any other licensee.
    (c) The output power at the remote site must not exceed 30 watts.
    (d) Automatic means must be provided to deactivate the remote 
transmitter in the event the carrier remains on for a period in excess 
of three minutes.
    (e) Operational fixed stations authorized pursuant to this section 
are exempt from the requirements of Sec. Sec.  90.425, 90.429, and 
90.559.
    (f) Any operations undertaken in a shared use environment must be 
conducted pursuant to an agreement between the licensee and each 
participant, as set forth in Sec.  90.179.

Sec.  90.559  Station Identification.

    (a) Conventional systems of communication shall be identified in 
accordance with existing regulations governing such matters.
    (b) Trunked systems of communication, except as noted in paragraph 
(c) of this section, shall be identified through the use of an automatic 
device which transmits the call sign of the base station facility at 30 
minute intervals. Such station identification shall be made on the 
lowest frequency in the base station trunk group assigned the licensee. 
Should this frequency be in use at the time station identification is 
required, such identification may be made at the termination of the 
communication in progress on this frequency. Identification may be made 
by voice or International Morse Code. When the call sign is transmitted 
in International Morse Code, it must be at a rate of between 15 to 20 
words per minute and by means of tone modulation of the transmitter, the 
tone frequency being between 800 and 1000 hertz.
    (c) Stations operating in the 769-775/799-805 MHz band that are 
licensed on an exclusive basis, and normally employ digital signals for 
the transmission of data, text, control codes, or digitized voice may 
also be identified by digital transmission of the call sign.

[[Page 433]]

A licensee that identifies its station in this manner must provide the 
Commission, upon its request, information sufficient to decode the 
digital transmission and ascertain the call sign transmitted.

Sec.  90.609  Special limitations on amendment of applications for assignment 
or transfer of authorizations for radio systems above 800 MHz.

    (a) [Reserved]
    (b) A license to operate a conventional or trunked radio system may 
not be assigned or transferred prior to the completion of construction 
of the facility. However, the Commission may give its consent to the 
assignment or transfer of control of such a license prior to the 
completion of construction where:
    (1) The assignment or transfer does not involve a substantial change 
in ownership or control of the authorized radio facilities; or,
    (2) The assignment or transfer is involuntary due to the licensee's 
insolvency, bankruptcy, incapacity, or death.
    (c) Licensees of constructed systems in any category are permitted 
to make partial assignments of an authorized grant to an applicant 
proposing to create a new system or to an existing licensee that has 
loaded its system to 70 mobiles per channel and is expanding that 
system. An applicant authorized to expand an existing system or to 
create a new system with frequencies from any category obtained through 
partial assignment will receive the assignor's existing license 
expiration date and loading deadline for the frequencies that are 
assigned. A licensee that makes a partial assignment of a station's 
frequencies will not be authorized to obtain additional frequencies for 
that station for a period of one year from the date of the partial 
assignment.
    (d) A constructed system originally licensed in the General Category 
that is authorized to operate in the conventional mode may be combined 
with an existing SMR system above 800 MHz authorized to operate in the 
trunked mode by assignment of an authorized grant of the General 
Category station to the SMR station.

Channels numbered above 200 may only be used subject to the power flux
  density limits at or beyond the Mexico border as stated in paragraph
  (4) of this section.

    (3) The specific channels that are available for licensing in the 
band 896-901/935-940 MHz within the Mexico border region are subject to 
Effective Radiated Power (ERP) and Antenna Height limitations as 
indicated in Table 3 below.

    (4) All channels in the 896-901/935-940 MHz band are available for 
assignment to U.S. stations within the Mexico border region if the 
maximum power flux density (pfd) of the station's transmitted signal at 
any point at or beyond the border does not exceed -107 dB (W/m\2\). The 
spreading loss must be calculated using the free space formula taking 
into account any antenna discrimination in the direction of the border. 
Authorizations for stations using channels allotted to Mexico on a 
primary basis will be secondary to Mexican operations and conditioned to 
require that licensees take immediate action to eliminate any harmful 
interference resulting from the station's transmitted signal exceeding -
107 dB (W/m\2\).
    (c) Use of 800 MHz Band in Canada Border Region. All operations in 
the 806-824/851-869 MHz band within 140 km (87 miles) of the U.S./Canada 
border (``U.S./Canada border area'') shall be in accordance with 
international agreements between the U.S. and Canada.
    (1) The U.S./Canada border area is divided into the following 
geographical regions (``Canada Border Regions''). U.S. primary channels 
are shown in the table by region. The remaining channels are primary to 
Canada (``Canada Primary channels'').

immediate action to eliminate any harmful interference resulting from 
the station's transmitted signal exceeding -107 dBW/m\2\ at or beyond 
the U.S./Canada border.
    (4) Except as specified in Sec.  90.616, channel assignments for 
stations to be located in the geographical area in Region 1 enclosed by 
the United States-Canada border, the meridian 71[deg] W and the line 
beginning at the intersection of 44[deg]25[min] N, 71[deg] W, then 
running by great circle arc to the intersection of 45[deg] N, 70[deg] W, 
then North along meridian 70[deg] W to the intersection of 
45[deg]45[min] N, then running West along 45[deg]45[min] N to the 
intersection of the United States-Canada border, will be only for 
channels 121 through 160, inclusive, and will be limited to assignments 
with 11 kHz or less necessary bandwidth. Coordination with Canada will 
be required for these channels.
    (5) Except as specified in Sec.  90.616, channel assignments for 
stations to be located in the geographical area in Region 3 enclosed by 
the meridian of 81[deg] W longitude, the arc of a circle of 100 km 
radius centered at 42[deg]39[min]30[sec] N latitude and 81[deg] W 
longitude at the northern shore of Lake Erie and drawn clockwise from 
the southerly intersection with 80[deg]30[min] W longitude to intersect 
the United States-Canada border West of 81[deg] W, and the United 
States-Canada border, will be only for channels 121 through 230, 
inclusive, and will be limited to assignments with 11 kHz or less 
necessary bandwidth. Coordination with Canada will be required for these 
channels. U.S. stations must protect Canadian stations operating on 
channels 121 through 230 within an area of 30 km radius from the center 
city coordinates (referenced to North American Datum 1983 (NAD83)) of 
London, Ontario (42[deg]59[min]00.1[sec] N, 81[deg]13[min]59.5[sec] W).
    (6) Additional channels available: Except as specified in Sec.  
90.616, the channels listed in table 28 are available for assignment in 
Regions 1-6 if the maximum power flux density (PFD) of the station's 
transmitted signal does not exceed the limits specified in tables 29 and

Sec.  90.621  Selection and assignment of frequencies.

    (a) Applicants for frequencies in the Public Safety and Business/
Industrial/Land Transportation Categories must specify on the 
application the frequencies on which the proposed system will operate 
pursuant to a recommendation by the applicable frequency coordinator. 
Applicants for frequencies in the SMR Category must request specific 
frequencies by including in their applications the frequencies 
requested.
    (1) For trunked systems, the assignment of frequencies will be made 
in accordance with applicable loading criteria and in accordance with 
the following:
    (i) Channels will be chosen and assigned in accordance with 
Sec. Sec.  90.615, 90.617, or 90.619.
    (ii) A mobile station is authorized to transmit on any frequency 
assigned to its associated base station.
    (iii) There are no limitations on the number of frequencies that may 
be trunked. Authorizations for non-SMR stations may be granted for up to 
20 trunked frequency pairs at a time in accordance with the frequencies 
listed in Sec. Sec.  90.615, 90.617, and 90.619.
    (2) For conventional systems the assignment of frequencies will be 
made in accordance with applicable loading criteria. Accordingly, 
depending upon the number of mobile units to be served, an applicant may 
either be required to share a channel, or, if an applicant shows a 
sufficient number of mobile units to warrant the assignment of one or 
more channels for its exclusive use, it may be licensed to use such 
channel or channels on an unshared basis in the area of operation 
specified in its application.
    (i) Channels will be chosen and assigned in accordance with 
Sec. Sec.  90.615, 90.617, or 90.619.
    (ii) A mobile station is authorized to transmit on any frequency 
assigned to its associated base station.
    (b) Stations authorized on frequencies listed in this subpart, 
except for those stations authorized pursuant to paragraph (g) of this 
section and EA-based and MTA-based SMR systems, will be assigned co-
channel frequencies solely on the basis of distance between fixed 
stations. In addition, contour overlap as detailed in paragraph (d) of 
this section will be the basis for geographic separation between fixed 
stations operating on adjacent-channel frequencies in the 809-817 MHz/
854-862 MHz sub-band, except where such fixed stations meet the distance 
separation criteria set out in this paragraph (b).
    (1) Except as indicated in paragraph (b)(4) of this section, no 
station in

[[Page 466]]

Channel Blocks A through V shall be less than 169 km (105 mi) distant 
from a co-channel station that has been granted channel exclusivity and 
authorized 1 kW ERP on any of the following mountaintop sites: Santiago 
Peak, Sierra Peak, Mount Lukens, Mount Wilson (California). Except as 
indicated in paragraph (b)(4) of this section, no incumbent licensee in 
Channel Blocks F1 through V that has received the consent of all 
affected parties or a certified frequency coordinator to utilize an 18 
dB[micro]V/m signal strength interference contour shall be less than 229 
km (142 mi) distant from a co-channel station that has been granted 
channel exclusivity and authorized 1 kW ERP on any of the following 
mountaintop sites: Santiago Peak, Sierra Peak, Mount Lukens, Mount 
Wilson (California).
    (2) The separation between co-channel stations that have been 
granted exclusivity and that are located at high sites in California 
north of 35[deg] N Latitude and west of 118[deg] W Longitude shall be 
determined as follows:
    (i) Required co-channel separations between common antenna sites are 
given by table 1. A channel group assigned to a station on a site listed 
in the vertical column may not be re-assigned to a station on a site 
listed in the horizontal column if there is an ``X'' in the box created 
by the intersection of the vertical and horizontal lines. The geographic 
coordinates listed in the table represent an average for each particular 
site; all locations within 1.6 km (1 mi) of the coordinates will be 
considered to be at that site.
    (ii) Required co-channel separations involving antenna sites not 
listed in table 1 shall be determined by Commission staff on a case by 
case basis. The interference potential of proposed assignments will be 
evaluated considering parameters such as antenna height, effective 
radiated power, terrain irregularities, and market conditions.

    (3) Except as indicated in paragraph (b)(4) of this section, 
stations in Channel Blocks A through V that have been granted channel 
exclusivity and are located in the State of Washington at the locations 
listed in the table below shall be separated from co-channel stations by 
a minimum of 169 km (105 mi). Except as indicated in paragraph (b)(4) of 
this section, incumbent licensees in Channel Blocks F1 through V that 
have received the consent of all affected parties or a certified 
frequency coordinator to utilize an 18 dB[micro]V/m signal strength 
interference contour, have been granted channel exclusivity and are 
located in the State of Washington at the locations listed in the table 
below shall be separated from co-channel stations by a minimum of 229 km 
(142 mi). Locations within one mile of the geographical coordinates 
listed in the table below will be considered to be at that site.

    (4) Upon an applicant's specific request to the Commission or a 
frequency coordinator, co-channel stations may be separated by less than 
113 km (70 mi) by meeting certain transmitter ERP and antenna height 
criteria. The following table indicates separations assignable to such 
co-channel stations for various transmitter power and antenna height 
combinations. The minimum separation permitted is 88 km (55 mi). 
Applicants will provide the Commission with a statement that the 
application is submitted for consideration under the table, a list of 
all co-channel stations within 113 km (70 mi), and the DHAATs and ERPs 
for these stations and the applicant's proposed station. Applicants 
seeking to be licensed for stations located at distances less than those 
prescribed in the table are required to secure a waiver and must submit 
with the application, in addition to the above, an interference 
analysis, based upon any of the generally-accepted terrain-based 
propagation models, that shows that co-channel stations would receive 
the same or greater interference protection than provided in the table. 
Requests for separations less than 88 km (55 mi) must also include an 
analysis of interference potential from mobile transmitters to existing 
co-channel base station receivers. Applicants seeking a waiver must 
submit with their application a certificate of service indicating that 
concurrent with the submission of the application to the Commission or a 
coordinator, all co-channel licensees within the applicable area were 
served with a copy of the application and all attachments thereto. 
Licensees thus served may file an opposition to the application within 
30 days from the date the application is filed with the Commission.
    (i) The directional height of the antenna above average terrain 
(DHAAT) is calculated from the average of the antenna heights above 
average terrain from 3 to 16 km (2 to 10 mi) from the proposed site 
along a radial extending in the direction of the existing station and 
the radials 15 degrees to either side of that radial.
    (ii) Except for the sites listed in paragraphs (b)(1), (b)(2), and 
(b)(3) of this section, additional co-channel distance separation must 
be afforded to an existing station from an applicant wishing to locate a 
station less than 113 km (70 mi) from a co-channel station, where either 
the applicant's or the existing station is located at sites with DHAATs 
of 458 m (1500 ft) and above. The separation between short-spaced co-
channel stations shall be determined as follows:
    (A) Calculate the DHAAT in each direction between every existing co-
channel station with 113 km (70 mi) and the proposed station.
    (B) In the table, locate the approximate ERP and DHAAT values for 
the proposed and existing stations.
    (C) When DHAAT values are greater than 458 m (1500 ft), use the 
required separation for 305 m (1000 ft) and add 1.6 km (1 mi) for every 
30.5 km (100 ft), or increment thereof, of DHAAT above 458 m (1500 ft) 
to the distance indicated in the table. If both the proposed existing 
stations have DHAATs of 458 m (1500 ft) or more, the additional distance 
is separately determined for each station and the combined distance is 
added to the distance obtained from the table. Protection to existing 
stations will be afforded only up to 113 km (70 mi).

\1\ Separations for stations on Santiago Peak, Sierra Peak, Mount
  Lukens, and Mount Wilson (CA) and the locations in the State of
  Washington listed in paragraph (b)(3) of this section are 56 km (35
  mi) greater than those listed in the table above. In the event of
  conflict between this table and the table of additional California
  high elevation sites shown in paragraph (b)(2) of this section, the
  latter will apply.
\2\ Distances shown are derived from the R-6602 curves and are based
  upon a non-overlap of the 22 dBu (F50,10) interference contour of the
  proposed station with the 40 dBu (F50,50) contour of the existing
  station(s). No consideration is given to the 40 dBu service contour of
  the proposed station and the 22 dBu contour of the existing
  station(s). The minimum separation of stations will be 88 km (55 mi).
\3\ All existing stations are assumed to operate with 1000 watts ERP.
  When the ERP and/or DHAAT of a proposed station or the DHAAT of an
  existing station is not indicated in the table, the next higher
  value(s) must be used.

    (5) The separation between co-channel systems may be less than the 
separations defined above if an applicant submits with its application 
letters of concurrence indicating that the applicant and each co-channel 
licensee within the specified separation agree to accept any 
interference resulting from the reduced separation between their 
systems. Each letter from a co-channel licensee must certify that the 
system of the concurring licensee is constructed and fully operational. 
The applicant must also submit with its application a certificate of 
service indicating that all concurring co-channel licensees have been 
served with an actual copy of the application.
    (6) A station located closer than the distances provided in this 
section to a co-channel station that was authorized as short-spaced 
under paragraph (b)(4) of this section shall be permitted to modify its 
facilities as long as the station does not extend its 22 dBu contour 
beyond its maximum 22 dBu contour (i.e., the 22 dBu contour calculated 
using the station's maximum power and antenna height at its original 
location) in the direction of the short-spaced station.
    (7) Offset frequencies in the 811-821/856-866 MHz band for use only 
within U.S./Mexico border area, as designated in Sec.  90.619(a), shall 
be considered co-channel with non-offset frequencies in this band as 
designated in Sec.  90.613. New applications for frequencies in this 
band for stations adjacent to the U.S./Mexico border area must comply 
with the co-channel separation provisions of this section.
    (c) Conventional systems authorized on frequencies in the Public 
Safety (except for those systems that have participated in a formal 
regional planning process as described in Sec.  90.16) and Business/
Industrial/Land Transportation categories which have not met the loading 
levels necessary for channel exclusivity will not be afforded co-channel 
protection.
    (d) Geographic separation between fixed stations operating on 
adjacent channels in the 809-817/854-862 MHz Mid-Band segment must be 
based on lack of contour overlap as detailed in paragraphs (d)(1) 
through (4), unless the co-channel distance separation criteria in 
paragraph (b) of this section are met.
    (1) Forward contour analysis. An applicant seeking to license a 
fixed station on a channel in the 809-817 MHz/854-862 MHz band segment 
will only be granted if the applicant's proposed interference contour 
creates no overlap with the 40 dBu F(50,50) contour of an incumbent 
operating a fixed station on an upper- or lower-adjacent channel. The 
applicant's interference contour is determined using the dBu level 
listed in the appropriate table in paragraph (d)(3) of

[[Page 470]]

this section. For this analysis the applicant shall plot the 
interference contour of its proposed fixed station at its proposed ERP 
but assume that any adjacent-channel incumbent licensee is operating at 
the maximum permitted ERP for the licensed antenna height.
    (2) Reciprocal contour analysis. In addition to the contour analysis 
described in paragraph (d)(1) of this section, any applicant seeking to 
license a fixed station on a channel in the 809-817 MHz/854-862 MHz band 
segment must also pass a reciprocal contour analysis. Under the 
reciprocal analysis, the interference contour, F(50,10) of an incumbent 
operating a fixed station on an upper- or lower-adjacent channel must 
create no contour overlap with the proposed 40 dBu F(50,50) contour of 
the applicant's fixed station. The incumbent's interference contour is 
determined using the dBu level listed in the appropriate table in 
paragraph (d)(3) of this section. For this analysis the applicant shall 
plot the coverage contour of its fixed station, F(50,50), at its 
proposed ERP and antenna height above average terrain but plot the 
interference contour, F(50,10), of any adjacent-channel incumbent 
licensee at its maximum permitted ERP for the licensed antenna height.
    (3) Contour matrix. Interference contour levels for the contour 
analysis described in paragraphs (d)(1) and (2) of this section are 
determined using Table 4 or Table 5 to this paragraph (d)(3). Table 4 is 
used to determine the interference contour F(50,10) level of a fixed 
station operating on a 12.5 kilohertz bandwidth channel while Table 5 is 
used to determine the interference contour F(50,10) level of a fixed 
station operating on a 25 kilohertz bandwidth channel. The dBu level of 
the interference contour is determined by cross-referencing the 
modulation type of the station operating on the 25 kilohertz bandwidth 
channel with the modulation type of the station operating on the 12.5 
kilohertz bandwidth channel.

    (4) Letters of concurrence. Applicants may submit applications which 
cause overlap under the forward contour analysis described in paragraph 
(d)(1) of this section provided the applicant includes a letter of 
concurrence from each incumbent that receives contour overlap. In the 
letter of concurrence, the incumbent operator must agree to accept any 
interference that occurs as a result of the contour overlap. Applicants 
may also submit applications which receive contour overlap under the 
reciprocal analysis described in paragraph (d)(2) of this section 
provided the applicant includes a letter of concurrence from each 
incumbent that causes contour overlap. In this case, the incumbent 
operator must state in its letter of concurrence that it does not object 
to the applicant receiving contour overlap from the incumbent's 
facility.
    (e) Frequencies in the 809-817/854-862 MHz bands listed as available 
for eligibles in the Public Safety and Business/

[[Page 474]]

Industrial/Land Transportation Categories are available for inter-
category sharing under the following conditions:
    (1) Channels in the Public Safety and Business/Industrial/Land 
Transportation categories will be available to eligible applicants in 
those categories only if there are no frequencies in their own category 
and no public safety systems are authorized on those channels under 
consideration to be shared.
    (2) Notwithstanding paragraph (e)(5) of this section, licensees of 
channels in the Business/Industrial/Land Transportation category may 
request a modification of the license, see Sec.  1.947 of this chapter, 
to authorize use of the channels for commercial operation. The licensee 
may also, at the same time or thereafter, seek authorization to transfer 
or assign the license, see Sec.  1.948 of this chapter, to any person 
eligible for licensing in the General or SMR categories. Applications 
submitted pursuant to this paragraph must be filed in accordance with 
the rules governing other applications for commercial channels, and will 
be processed in accordance with those rules. Grant of requests submitted 
pursuant to this paragraph is subject to the following conditions:
    (i) A licensee that modifies its license to authorize commercial 
operations will not be authorized to obtain additional 800 MHz Business/
Industrial/Land Transportation category channels for sites located 
within 113 km (70 mi.) of the station for which the license was 
modified, for a period of one year from the date the license is 
modified. This provision applies to the licensee, its controlling 
interests and their affiliates, as defined in Sec.  1.2110 of this 
chapter.
    (ii) With respect to licenses the initial application for which was 
filed on or after November 9, 2000, requests submitted pursuant to 
paragraph (e)(2) of this section may not be filed until five years after 
the date of the initial license grant. In the case of a license that is 
modified on or after November 9, 2000 to add 800 MHz Business/
Industrial/Land Transportation frequencies or to add or relocate base 
stations that expand the licensee's interference contour, requests 
submitted pursuant to paragraph (e)(2) of this section for these 
frequencies or base stations may not be filed until five years after 
such modification.
    (iii) Requests submitted pursuant to paragraph (e)(2) of this 
section must include a certification that written notice of the 
modification application has been provided to all Public Safety 
licensees, see Sec.  90.20(a), with base stations within 113 km (70 mi.) 
of the site of the channel(s) for which authorization for commercial use 
is sought that operate within 25 kHz of the center of those channel(s). 
If, pursuant to paragraph (e)(2) of this section, modification and 
assignment or transfer applications are filed at different times, the 
written notice required by this paragraph must be provided each time.
    (iv) The applicant must certify that it will take reasonable 
precautions to avoid causing harmful interference to Public Safety 
licensees, see Sec.  90.20(a), and to take such action as may be 
necessary to eliminate interference to such licensees caused by its 
operations. (When an assignment or transfer application is filed 
pursuant to paragraph (e)(2) of this section, this representation is 
required only of the assignee or transferee.) Licensees of stations 
suffering or causing harmful interference are expected to cooperate and 
resolve this problem by mutually satisfactory arrangements. If the 
licensees are unable to do so, the Commission may impose restrictions 
including specifying the transmitter power, antenna height, or area or 
hours of operation.
    (3) Licensees granted authorizations pursuant to paragraph (e)(2) of 
this section may at any time request modification of the license to 
authorize use of the channels consistent with the rules governing the 
category to which they are allocated, provided that the licensee meets 
the applicable eligibility requirements.
    (4) [Reserved]
    (5) The frequency coordinator must certify that frequencies are not 
available in the applicant's own category, and coordination is required 
from the applicable out-of-category coordinator.
    (6) The out-of-category licensee must operate by the rules 
applicable to the category to which the frequency is allocated.

[[Page 475]]

    (f) Licensees of channels in the Business/Industrial/Land 
Transportation Categories in the 896-901/935-940 MHz bands may request a 
modification of the license, see Sec.  1.947 of this chapter, to 
authorize use of the channels for commercial operation. The licensee may 
also, at the same time, or thereafter, seek authorization to transfer or 
assign the license, see Sec.  1.948 of this chapter, to any person 
eligible for licensing in the General or SMR categories. Applications 
submitted pursuant to this paragraph must be filed in accordance with 
the rules governing other applications for commercial channels, and will 
be processed in accordance with those rules.
    (g) Applications for Public Safety systems (both trunked and 
conventional) in the 806-809/851-854 MHz bands will be assigned and 
protected based on the criteria established in the appropriate regional 
plan. See Sec.  90.16 and the Report and Order in General Docket 87-112.

Sec.  90.623  Limitations on the number of frequencies assignable 
for conventional systems.

    (a) The maximum number of frequency pairs that may be assigned to a 
licensee for operation in the conventional mode in a given area is five 
(5).
    (b) Where an applicant proposes to operate a conventional radio 
system to provide facilities for the use of a single person or entity 
eligible under subparts B or C of this part, the applicant may be 
assigned only the number of frequency pairs justified on the basis of 
the requirement of the proposed single user of the system.
    (c) No non-SMR licensee will be authorized an additional frequency 
pair for a conventional system within 64 kilometers (40 miles) of an 
existing conventional system, except where:
    (1) The additional frequency pair will be used to provide radio 
facilities to a

[[Page 476]]

single entity and the additional frequency pair is justified on the 
basis of the requirements of the proposed single user; or,
    (2) The licensee's existing frequency pair(s) is loaded to 
prescribed levels.
    (d) No licensee will be authorized frequencies for a conventional 
system if that licensee is operating an unloaded trunked system or has 
an application pending for a trunked system to serve multiple 
subscribers within 64 km (40 miles) of the requested conventional 
system.

Sec.  90.625  Other criteria to be applied in assigning channels for use 
in conventional systems of communication.

    (a) Where an applicant certifies on its application that a channel 
will be loaded to 70 mobile stations, that channel will be made 
available to that applicant for its exclusive use in the area in which 
it proposes to operate. If the showing made justifies the assignment of 
more than one channel to the applicant, additional frequencies will be 
authorized.
    (b) Where an applicant proposes to furnish service to eligibles 
under subparts B or C of this part on a commercial basis using a 
conventional system of communication, the applicant will be considered 
on the same basis as that of an applicant for private or shared 
communication facilities.
    (c) No person authorized to operate any radio facility under the 
provisions of this subpart shall have a right to protest proposals on 
grounds other than violation of or inconsistency with the provisions of 
this subpart. All grants are made subject to this condition and to the 
other conditions and standards set out in this subpart.

Sec.  90.629  Extended implementation period.

    Applicants requesting frequencies for either trunked or conventional 
operations may be authorized a period of up to five (5) years for 
constructing and placing a system in operation in accordance with the 
following:
    (a) The applicant must justify an extended implementation period. 
The justification must describe the proposed system, state the amount of 
time necessary to construct and place the system in operation, identify 
the number of base stations to be constructed and placed in operation 
during each year of the extended construction period, and show that:
    (1) The proposed system will require longer than twelve (12) months 
to construct and place in operation because of its purpose, size, or 
complexity; or
    (2) The proposed system is to be part of a coordinated or integrated 
wide-area system which will require more than twelve (12) months to 
plan, approve, fund, purchase, construct, and place in operation; or

[[Page 477]]

    (3) The applicant is required by law to follow a multi-year cycle 
for planning, approval, funding, and purchasing the proposed system.
    (b) Where an applicant is required by law to follow a multi-year 
cycle for planning, approval, funding and purchasing a proposed system, 
the applicant must indicate whether funding approval has been obtained 
and if not, when such funding approval is expected.
    (c) Authorizations under this section are conditioned upon the 
licensee constructing and placing its system in operation within the 
authorized implementation period and in accordance with an approved 
implementation plan of up to five years. Licensees must notify the 
Commission annually, using FCC Form 601, that they are in compliance 
with their yearly station construction commitments, but may request 
amendment to these commitments at the time they file their annual 
certification. If the Commission approves the requested amendments to a 
licensee's implementation commitments, the licensee's extended 
implementation authority will remain in effect. If, however, the 
Commission concludes, at this or any other time, that a licensee has 
failed to meet its commitments, the Commission will terminate authority 
for the extended implementation period. When the Commission terminates 
an extended implementation authority, the affected licensee will be 
given six months from the date of termination to complete system 
construction. At the end of any licensee's extended implementation 
period, authorizations for all stations not constructed and placed in 
operation will be cancelled. Trunked systems granted an extended 
implementation period must comply with the channel loading requirements 
of section 90.631(b). Conventional channels not loaded to 70 mobile 
units may be subject to shared use by the addition of other licensees.
    (d) [Reserved]
    (e) As of March 18, 1996, Specialized Mobile Radio systems are not 
eligible for extended implementation periods under this section. 
Additionally, all 800 MHz SMR licensees that are operating under 
extended implementation authority as of March 18, 1996 must, by May 16, 
1996, demonstrate that continuing to allow them to have an extended 
period of time to construct their facilities is warranted and furthers 
the public interest. If a licensee's extended implementation authority 
showing is approved by the Bureau, such licensee will be afforded an 
extended implementation of two years or the remainder of its current 
extended implementation period, whichever is shorter. Upon the 
termination of this period, the authorizations for those facilities that 
remain unconstructed will terminate automatically. If a licensee with a 
current extended implementation period fails to submit the showing 
mentioned above within the designated timeframe or submits an 
insufficient or incomplete showing, such licensee will have six months 
from the last day on which it could timely file such a showing or from 
the disapproval of its request to construct the remaining facilities 
covered under its implementation plan to construct any unconstructed 
facilities for which it is authorized. The authorizations for those 
facilities remaining unconstructed after this six-month period will 
terminate automatically.
    (f) Pursuant to Sec.  90.155(b), the provisions of this section 
shall apply to local government entities applying for any frequency in 
the Public Safety Pool.

[58 FR 34379, June 25, 1993, as amended at 61 FR 6157, Feb. 16, 1996; 63 
FR 68969, Dec. 14, 1998; 65 FR 60877, Oct. 13, 2000; 69 FR 67489, Nov. 
22, 2004]



Sec.  90.631  Trunked systems loading, construction 
and authorization requirements.

    (a) Non-SMR trunked systems will be authorized on the basis of a 
loading criteria of one hundred (100) mobile stations per channel. For 
purposes of determining compliance with trunked system loading 
requirements under this subpart, the term ``mobile station'' includes 
vehicular and portable mobile units and control stations.
    (b) Each applicant for a non-SMR trunked system must certify that a 
minimum of seventy (70) mobiles for each channel authorized will be 
placed into operation within five (5) years of the initial license 
grant.

[[Page 478]]

    (c) Except for SMR applicants and as provided in paragraph (d) of 
this section, an applicant seeking to expand a trunked system by 
requesting additional channels from the Commission, or through 
intercategory sharing, or through an assignment, must have a loading 
level of seventy (70) mobiles per channel on the existing system that is 
the subject of the expansion request.
    (d) In rural areas, a licensee of a trunked system may request to 
increase its system capacity by five more channels than it has 
constructed without meeting the loading requirements specified in 
paragraphs (b) and (c) of this section. A rural area is defined for 
purposes of this section as being beyond a 100-mile radius of the 
following designated centers of the following urban areas: New York, NY; 
Los Angeles, CA; Chicago, IL; Philadelphia, PA; San Francisco, CA; 
Detroit, MI; Boston, MA; Houston, TX; Washington, DC; Dallas-Fort Worth, 
TX; Miami, FL; Cleveland, OH; St. Louis, MO; Atlanta, GA; Pittsburgh, 
PA; Baltimore, MD; Minneapolis-St. Paul, MN; Seattle, WA; San Diego, CA; 
and Tampa-St.Petersburg, FL. The coordinates for the centers of these 
areas are those referenced in Sec.  90.741, except that the coordinates 
(referenced to North American Datum 1983 (NAD83)) for Tampa-St. 
Petersburg are latitude 28[deg]00[min]1.1[sec] N, longitude 
82[deg]26[min]59.3[sec] W.
    (e) Except as provided in Sec.  90.629, licensees of trunked 
facilities must complete construction within one year.
    (f) If a station is not placed in permanent operation, in accordance 
with the technical parameters of the station authorization, within one 
year, except as provided in Sec.  90.629, its license cancels 
automatically. For purposes of this section, a base station is not 
considered to be placed in operation unless at least two associated 
mobile stations, or one control station and one mobile station, are also 
placed in operation.
    (g) Wide area systems may be authorized to persons eligible for 
licensing under subparts B or C of this part upon an appropriate showing 
of need. Remote or satellite stations of wide area systems in the Public 
Safety, Special Emergency, Telephone Maintenance, and Power Radio 
Services may be authorized on a primary basis if such stations are the 
first to be authorized in their area of operation on the frequency or 
group of frequencies. Remote or satellite stations of wide area systems 
in all other services will be authorized only on a secondary, non-
interference basis to cochannel licensees. To determine system loading, 
the total number of mobile units and control stations operating in the 
wide-area system shall be counted with respect to the total number of 
base station frequencies assigned to the system.
    (h) Regional, statewide, or ribbon configuration systems may be 
authorized to persons eligible for licensing under subparts B or C of 
this part upon an appropriate showing of need. In a ribbon, regional or 
statewide system, a mobile station will be counted for channel loading 
purposes only for the base station facility in the geographic area in 
which it primarily operates. If this cannot be determined, it will be 
counted fractionally over the number of base station facilities with 
which it communicates regularly.

    Editorial Note: For Federal Register citations affecting Sec.  
90.631, see the List of CFR Sections Affected, which appears in the 
Finding Aids section of the printed volume and at www.govinfo.gov.



Sec.  90.633  Conventional systems loading requirements.

    (a) Non-SMR conventional systems of communication will be authorized 
on the basis of a minimum loading criteria of seventy (70) mobile 
stations for each channel authorized.
    (b) A channel will not be assigned to additional licensees when it 
is loaded to 70 mobile stations. Where a licensee does not load a 
channel to 70 mobiles the channel will be available for assignment to 
other licensees. All authorizations for conventional systems are issued 
subject to this potential channel sharing condition.
    (c) Except as provided in Sec.  90.629 of this part, licensees of 
conventional systems must place their authorized stations in operation 
not later than one year after the date of grant of the system license.

[[Page 479]]

    (d) If a station is not placed in operation within one year, except 
as provided in Section 90.629 of this part, the license cancels 
automatically. For purposes of this section, a base station is not 
considered to be in operation unless at least one associated mobile 
station is also in operation.
    (e) A non-SMR licensee may apply for additional frequency pairs if 
its authorized conventional channel(s) is loaded to seventy (70) 
mobiles. Applications may be considered for additional channels in areas 
where spectrum is still available and not applied for, even if the 
already authorized channel(s) is not loaded to 70 mobile units, upon an 
appropriate demonstration of need.
    (f) Wide area systems may be authorized to persons eligible for 
licensing under subparts B or C of this part upon an appropriate showing 
of need. For loading purposes, if the total number of mobile stations 
justifies the total number of authorized based frequencies in a given 
area, the system will be construed to be loaded.
    (g) Regional, statewide, or ribbon configuration systems may be 
authorized to persons eligible for licensing under subparts B or C of 
this part upon an appropriate showing of need. In a ribbon, regional or 
statewide system, a mobile station will be counted for channel loading 
purposes only for the base station facility in the geographic area in 
which it primarily operates. If this cannot be determined, it will be 
counted fractionally over the number of base station facilities with 
which it communicates regularly.

Sec.  90.637  Restrictions on operational fixed stations.

    (a) Except for control stations, operational fixed operations will 
not be authorized in the 806-824 MHz, 851-869 MHz, 896-901 MHz, or 935-
940 MHz bands. This does not preclude secondary fixed tone signaling and 
alarm operations authorized in Sec.  90.235 or in paragraph (c) of this 
section.
    (b) Control stations associated with one or more mobile relay 
stations will be authorized only on the assigned frequency of the 
associated mobile station. Use of a mobile service frequency by a 
control station of a mobile relay system is subject to the condition 
that harmful interference shall not be caused to stations of licensees 
authorized to use the frequency for mobile service communications.
    (c) Trunked and conventional systems that have exclusive-use status 
in their respective geographic areas may conduct fixed ancillary 
signaling and

[[Page 480]]

data transmissions subject to the following requirements:
    (1) All operations must be on a secondary, non-interference basis to 
the primary mobile operation of any other licensee.
    (2) The output power at the remote site must not exceed 30 watts.
    (3) Any fixed transmitters will not count toward meeting the mobile 
loading requirements nor be considered in whole or in part as a 
justification for authorizing additional frequencies in the licensee's 
mobile system.
    (4) Automatic means must be provided to deactivate the remote 
transmitter in the event the carrier remains on for a period in excess 
of three minutes.
    (5) Operational fixed stations authorized pursuant to the provisions 
of paragraphs (c) and (d) of this section are exempt from the 
requirements of Sec. Sec.  90.425 and 90.429.
    (d) Conventional systems that do not have exclusive-use status in 
their respective geographic areas may conduct fixed ancillary signaling 
and data transmissions only in accordance with all the provisions of 
Sec.  90.235.

Sec.  90.645  Permissible operations.

    Conventional and trunked radio systems may be used:
    (a) Only for purposes expressly allowed under this part.
    (b) Only persons who are eligible for facilities, either under this 
subpart or in the radio service included under subparts B or C of this 
part.
    (c) Except for licensees classified as CMRS providers under part 20 
of this chapter, only for the transmission of messages or signals 
permitted in the services is which the participants are eligible.
    (d) For digital or analog transmissions.
    (e) An SMRS licensee or a licensee who has been authorized a 
channel(s) on an exclusive basis, may use the system for the 
transmission of any base/mobile message, page or signal permitted in the 
service in which the participants are eligible.
    (f) Where the channel(s) is assigned to an SMRS licensee or 
exclusively to a single licensee, or where all users of a system agree, 
more than a single emission may be utilized within the authorized 
bandwidth. In such cases, the frequency stability requirements of Sec.  
90.213 shall not apply, but out-of-band emission limits of Sec.  90.209 
shall be met.
    (g) Up to five (5) contiguous 809-816/854-861 band channels as 
listed in Sec. Sec.  90.615, 90.617, and 90.619 may be authorized after 
justification for systems requiring more than the normal single channel 
bandwidth. If necessary, licensees may trade channels amongst themselves 
in order to obtain contiguous frequencies. Notification of such proposed 
exchanges shall be made to the appropriate frequency coordinator(s) and 
to the Commission by filing an application for license modification.
    (h) Up to 10 contiguous 896-901/935-940 MHz band channels as listed 
in Sec.  90.617 may be combined for systems requiring more than the 
normal single channel bandwidth. If necessary, licensees may trade 
channels amongst themselves in order to obtain contiguous frequencies. 
Notification of such proposed exchanges shall be made to the appropriate 
frequency coordinator(s) and to the Commission by filing an application 
for license modification.
    (i) Paging operations may be utilized on multiple licensed 
facilities (community repeaters) only when all licensees of the facility 
agree to such use.

Sec.  90.647  Station identification.

    (a) Conventional systems of communication shall be identified in 
accordance with existing regulations governing such matters.
    (b) Trunked systems of communication, except as noted in paragraph 
(c) of this section, shall be identified through the use of an automatic 
device which transmits the call sign of the base station facility at 30 
minute intervals. Such station identification shall

[[Page 481]]

be made on the lowest frequency in the base station trunk group assigned 
the licensee. Should this frequency be in use at the time station 
identification is required, such identification may be made at the 
termination of the communication in progress on this frequency. 
Identification may be made by voice or International Morse Code. When 
the call sign is transmitted in International Morse Code, it must be at 
a rate of between 15 to 20 words per minute and by means of tone 
modulation of the transmitter, the tone frequency being between 800 and 
1000 hertz.
    (c) Stations operating in either the 806-824/851-869 MHz or 896-901/
935-940 MHz bands that are licensed on an exclusive basis, and normally 
employ digital signals for the transmission of data, text, control 
codes, or digitized voice may also be identified by digital transmission 
of the call sign. A licensee that identifies its station in this manner 
must provide the Commission, upon its request, information sufficient to 
decode the digital transmission and ascertain the call sign transmitted.
    (d) Notwithstanding the requirements set forth in this paragraph, 
systems operated by geographic area CMRS licensees are subject only to 
the station identification requirements of Sec.  90.425(e).

Sec.  90.651  Supplemental reports required of licensees authorized 
under this subpart.

    Licensees of conventional systems must notify the Commission in 
accordance with Sec.  1.946 of this chapter of the number of mobile 
units placed in operation within their construction period.

[63 FR 68970, Dec. 14, 1998]

    Editorial Note: At 63 FR 10397, Mar. 4, 1999, Sec.  90.651 was 
amended by revising paragraph (c), effective Apr. 5, 1999. However, 
Sec.  90.651, as revised at 63 FR 68970, Dec. 14, 1998, effective Feb. 
12, 1999, did not contain paragraph (c), and the amendment could not be 
incorporated.



Sec.  90.655  Special licensing requirements for Specialized 
Mobile Radio systems.

    End users of conventional or trunked Specialized Mobile Radio 
systems that have control stations that require FAA clearance, as 
specified in Sec. Sec.  17.7 through 17.17 of this chapter, or that may 
have a significant environmental effect, as defined by Sec.  1.1307, or 
that are located in a ``quiet zone'', as defined by Sec.  1.924 of this 
chapter must be individually licensed for such control stations prior to 
construction or operation. All other end users' operations will be 
within the scope of the base station licensee. All end users, however, 
continue to be responsible to comply with 47 CFR part 90 and other 
federal laws.

[57 FR 40850, Sept. 8, 1992, as amended at 63 FR 68970, Dec. 14, 1998]



Sec.  90.656  Responsibilities of base station licensees of Specialized 
Mobile Radio systems.

    (a) The licensees of base stations that provide Specialized Mobile 
Radio service on a commercial basis of the use of individuals, Federal 
government agencies, or persons eligible for licensing under either 
subparts B or C of this part will be responsible for exercising 
effective operational control over all mobile and control stations that 
communicate with the base station. The base station licensee will be 
responsible for assuring that its system is operated in compliance with 
all applicable rules and regulations.
    (b) Customers that operate mobile units on a particular Specialized 
Mobile Radio system will be licensed to that system. A customer that 
operates temporarily on more than one system will be deemed, when 
communicating with the other system, to be temporarily licensed to the 
other system and for that temporary period, the licensee of the other 
system will assume the same licensee responsibility for the customer's 
mobile station(s) as if the customer's stations were licensed to that 
other system.

Policies Governing the Licensing and Use of MTA-Based SMR Systems in the 
                        896-901/935-940 MHz Band



Sec.  90.661  MTA-based SMR service areas.

    MTA licenses for SMR spectrum blocks in the 896-901/935-940 MHz band 
listed in table 4B of Sec.  90.617(d) are available in 51 Major Trading 
Areas (MTAs) as defined in Sec.  90.7. Within these MTAs, licenses will 
be authorized in ten channel blocks as specified in table 4B of Sec.  
90.617(d) through the competitive bidding procedures described in 
subpart U of this part.

[60 FR 21991, May 4, 1995]



Sec.  90.663  MTA-based SMR system operations.

    (a) MTA-based licensees authorized in the 896-901/935-940 MHz band 
pursuant to Sec.  90.661 may construct and operate base stations using 
any frequency identified in their spectrum block anywhere within their 
authorized MTA, provided that:
    (1) The MTA licensee affords protection, in accordance with Sec.  
90.621(b), to all sites for which applications were filed on or prior to 
August 9, 1994.
    (2) The MTA licensee complies with any rules and international 
agreements that restrict use of frequencies identified in their spectrum 
block, including the provisions of Sec.  90.619 relating to U.S./
Canadian and U.S./Mexican border areas.
    (3) The MTA licensee limits its field strength at any location on 
the border of the MTA service area in accordance with Sec.  90.671 and 
masks its emissions in accordance with Sec.  90.669.
    (b) In the event that the authorization for a previously authorized 
co-channel station within the MTA licensee's authorized spectrum block 
is terminated or revoked, the MTA licensee's co-channel obligations to 
such station will cease upon deletion of the facility from the 
Commission's licensing record. The MTA licensee then will be able to 
construct and operate base stations using such frequency.

[60 FR 21991, May 4, 1995]



Sec.  90.665  Authorization, construction and implementation of MTA licenses.

    (a) MTA licenses in the 896-901/935-940 MHz band will be issued for 
a term not to exceed ten years.
    (b) MTA licensees in the 896-901/935-940 MHz band will be permitted 
five years to construct their stations. This five-year period will 
commence with the issuance of the MTA-wide authorization and will apply 
to all of the licensee's stations within the MTA spectrum block, 
including any stations that may have been subject to an earlier 
construction deadline arising from a pre-existing authorization.
    (c) Each MTA licensee in the 896-901/935-940 MHz band must, three 
years from the date of license grant, construct and place into operation 
a sufficient number of base stations to provide coverage to at least 
one-third of the population of the MTA; further, each MTA licensee must 
provide coverage to at least two-thirds of the population of the MTA 
five years from the date of license grant. Alternatively, an MTA 
licensee must demonstrate, through a showing to the Commission five 
years from the date of license grant, that it is providing substantial 
service. An MTA licensee must, three years from license grant, either 
show that the \1/3\ population coverage standard has been satisfied, or 
provide written notification that it has elected to show substantial 
service to the MTA five years from license grant. In addition, as part 
of the election to provide a substantial service showing, each MTA 
licensee must, three years from license grant, indicate how it expects 
to demonstrate substantial service at five years. The MTA licensee must 
meet the population coverage benchmarks regardless of the extent to 
which incumbent licensees are present within the MTA block.
    (d) MTA licensees who fail to meet the coverage requirements imposed 
at either the third or fifth years of their license term, or to make a 
convincing showing of substantial service, will forfeit the portion of 
the MTA license

[[Page 483]]

that exceeds licensed facilities constructed and operating on the date 
of the MTA license grant.

[60 FR 21991, May 4, 1995, as amended at 60 FR 48918, Sept. 21, 1995; 60 
FR 61487, Nov. 30, 1995; 64 FR 39942, July 23, 1999]



Sec.  90.667  Grandfathering provisions for incumbent licensees.

    (a) These provisions apply to all 900 MHz SMR licensees who obtained 
licenses or filed applications for secondary sites on or before August 
9, 1994 (``incumbent licensees''), as well as to all 900 MHz SMR 
licensees who obtained authorizations pursuant to Sec.  90.173(k). An 
incumbent licensee's service area shall be defined by its originally-
licensed 40 dBu field strength contour. Incumbent licensees are 
permitted to add new or modify transmit sites in this existing service 
area without prior notification to the Commission so long as their 
original 40 dBu field strength contour is not expanded.
    (b) Incumbent licensees operating at multiple sites may, after grant 
of MTA licenses has been completed, exchange multiple site licenses for 
a single license, authorizing operations throughout the contiguous and 
overlapping 40 dBu field strength contours of the multiple sites. 
Incumbents exercising this license exchange option must submit specific 
information for each of their external base sites after the close of the 
900 MHz SMR auction.
    (c) Applications in the 900 MHz SMR service for secondary sites 
filed after August 9, 1994 shall be authorized on a secondary, non-
interference basis to MTA licensee operations. No secondary sites shall 
be granted on this basis in an MTA once the MTA licensee has been 
selected.

[60 FR 48918, Sept. 21, 1995]



Sec.  90.669  Emission limits.

    (a) On any frequency in an MTA licensee's spectrum block that is 
adjacent to a non-MTA frequency, the power of any emission shall be 
attenuated below the transmitter power (P) by at least 43 plus 10 
log10(P) decibels or 80 decibels, whichever is the lesser 
attenuation.

    Note: The measurements of emission power can be expressed in peak or 
average values, provided they are expressed in the same parameters as 
the transmitter power.

    (b) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.

[60 FR 21992, May 4, 1995]



Sec.  90.671  Field strength limits.

    The predicted or measured field strength at any location on the 
border of the MTA service area for MTA licensees shall not exceed 40 
dBuV/m unless all bordering MTA licensees agree to a higher field 
strength. MTA licensees are also required to coordinate their frequency 
usage with so-channel adjacent MTA licensees and all other affected 
parties. To the extent that a single entity obtains licenses for 
adjacent MTAs on the same channel block, it will not be required to 
coordinate its operations in this manner. In the event that this 
standard conflicts with the MTA licensee's obligation to provide co-
channel protection to incumbent licensees under Sec.  90.621(b), the 
requirements of Sec.  90.621(b) shall prevail.

[60 FR 21992, May 4, 1995]

            Procedures and Process--Unacceptable Interference



Sec.  90.672  Unacceptable interference to non-cellular 800 MHz licensees 
from 800 MHz cellular systems or part 22 Cellular Radiotelephone systems, 
and within the 900 MHz narrowband segments, and to narrowband 900 MHz 
licensees from 900 MHz broadband licensees.

    (a) Definition. Except as provided in 47 CFR 90.617(k), unacceptable 
interference to non-cellular licensees in the 800 MHz band from 800 MHz 
cellular systems or part 22 of this chapter, Cellular Radiotelephone 
systems; unacceptable interference within the 900 MHz narrowband 
segment; and unacceptable interference to narrowband 900 MHz licensees 
from 900 MHz broadband licensees, will be deemed to occur when the below 
conditions are met:
    (1) A transceiver at a site at which interference is encountered:

[[Page 484]]

    (i) Is in good repair and operating condition, and is receiving:
    (A) From the 800 MHz band, a median desired signal strength of -104 
dBm or higher if operating in the 800 MHz band, or a median desired 
signal strength of -88 dBm if operating in the 900 MHz narrowband 
segment, as measured at the R.F. input of the receiver of a mobile unit; 
or
    (B) From the 800 MHz band, a median desired signal strength of -101 
dBm or higher if operating in the 800 MHz band, or a median desired 
signal strength of -85 dBm if operating in the 900 MHz narrowband 
segment; or, as measured at the R.F. input of the receiver of a portable 
i.e., hand-held unit;
    (C) From the 900 MHz broadband segment, a median desired signal 
strength of -104 dBm or higher if operating in the 900 MHz narrowband 
segment, as measured at the R.F. input of the receiver of a mobile unit; 
or
    (D) From the 900 MHz broadband segment, median desired signal 
strength of -101 dBm or higher if operating in the 900 MHz narrowband 
segment, as measured at the R.F. input of the receiver of a portable, 
i.e., hand-held unit; and either
    (ii) Is a voice transceiver:
    (A) With manufacturer published performance specifications for the 
receiver section of the transceiver equal to, or exceeding, the minimum 
standards set out in paragraph (b) of this section, and;
    (B) Receiving an undesired signal or signals which cause the 
measured Carrier to Noise plus Interference (C/(I + N)) ratio of the 
receiver section of said transceiver to be less than 20 dB if operating 
in the 800 MHz band, or less than 17 dB if operating in the 900 MHz 
narrowband segment, or;
    (iii) Is a non-voice transceiver receiving an undesired signal or 
signals which cause the measured bit error rate (BER) (or some 
comparable specification) of the receiver section of said transceiver to 
be more than the value reasonably designated by the manufacturer.
    (2) Provided, however, that if the receiver section of the mobile or 
portable voice transceiver does not conform to the standards set out in 
paragraph (b) of this section, then that transceiver shall be deemed 
subject to unacceptable interference only at sites where the median 
desired signal satisfies the applicable threshold measured signal power 
in paragraph (a)(1)(i) of this section after an upward adjustment to 
account for the difference in receiver section performance. The upward 
adjustment shall be equal to the increase in the desired signal required 
to restore the receiver section of the subject transceiver to the 20 dB 
C/(I + N) ratio of paragraph (a)(1)(ii)(B) of this section. The adjusted 
threshold levels shall then define the minimum measured signal power(s) 
in lieu of paragraph (a)(1)(i) of this section at which the licensee 
using such non-compliant transceiver is entitled to interference 
protection.
    (b) Minimum receiver requirements. Voice transceivers capable of 
operating in the 806-824 MHz portion of the 800 MHz band, or in the 900 
MHz narrowband segment, shall have the following minimum performance 
specifications in order for the system in which such transceivers are 
used to claim entitlement to full protection against unacceptable 
interference. (See paragraph (a)(2) of this section.)
    (1) Voice units intended for mobile use: 75 dB intermodulation 
rejection ratio; 75 dB adjacent channel rejection ratio; -116 dBm 
reference sensitivity.
    (2) Voice units intended for portable use: 70 dB intermodulation 
rejection ratio; 70 dB adjacent channel rejection ratio; -116 dBm 
reference sensitivity.
    (3) Voice units intended for mobile or portable use in the 900 MHz 
narrowband segment: 60 dB intermodulation rejection ratio; 60 dB 
adjacent channel rejection ratio; -116 dBm reference sensitivity.

[85 FR 43141, July 15, 2020]



Sec.  90.673  Obligation to abate unacceptable interference.

    (a) Strict Responsibility. Any licensee who, knowingly or 
unknowingly, directly or indirectly, causes or contributes to causing 
unacceptable interference to a non-cellular licensee in the 800 MHz 
band, as defined in this chapter, shall be strictly accountable to abate 
the interference, with full cooperation and utmost diligence, in the 
shortest time practicable. Interfering

[[Page 485]]

licensees shall consider all feasible interference abatement measures, 
including, but not limited to, the remedies specified in the 
interference resolution procedures set forth in this chapter. This 
strict responsibility obligation applies to all forms of interference, 
including out-of-band emissions and intermodulation.
    (b) Joint and Several Responsibility. If two or more licensees 
knowingly or unknowingly, directly or indirectly, cause or contribute to 
causing unacceptable interference to a non-cellular licensee in the 800 
MHz band, as defined in this chapter, such licensees shall be jointly 
and severally responsible for abating interference, with full 
cooperation and utmost diligence, in the shortest practicable time. This 
joint and several responsibility rule requires interfering licensees to 
consider all feasible interference abatement measures, including, but 
not limited to, the remedies specified in the interference resolution 
procedures set forth in this chapter. This joint and several 
responsibility rule applies to all forms of interference, including out-
of-band emissions and intermodulation.
    (1) This joint and several responsibility rule requires interfering 
licensees to consider all feasible interference abatement measures, 
including, but not limited to, the remedies specified in the 
interference resolution procedures set forth in Sec.  90.674(c). This 
joint and several responsibility rule applies to all forms of 
interference, including out-of-band emissions and intermodulation.
    (2) Any licensee that can show that its signal does not directly or 
indirectly, cause or contribute to causing unacceptable interference to 
a non-cellular licensee in the 800 MHz band, as defined in this chapter, 
shall not be held responsible for resolving unacceptable interference. 
Notwithstanding, any licensee that receives an interference complaint 
from a public safety/CII licensee shall respond to such complaint 
consistent with the interference resolution procedures set forth in this 
chapter.

[69 FR 67849, Nov. 22, 2004]



Sec.  90.674  Interference resolution procedures.

    (a) Initial Notification. Any non-cellular licensee operating in the 
806-824/851-869 MHz band who reasonably believes it is receiving 
unacceptable interference, as described in Sec.  90.672, shall provide 
an initial notification of the interference incident. This initial 
notification of an interference incident shall be sent to all part 22 of 
this chapter Cellular Radiotelephone licensees and ESMR licensees who 
operate cellular base stations (``cell sites'') within 1,524 meters 
(5,000 feet) of the interference incident.
    (1) The initial notification of interference shall include the 
following information on interference:
    (i) The specific geographical location where the interference 
occurs, and the time or times at which the interference occurred or is 
occurring;
    (ii) A description of its scope and severity, including its source, 
if known;
    (iii) The relevant Commission licensing information of the party 
suffering the interference; and
    (iv) A single point of contact for the party suffering the 
interference.
    (2) ESMR licensees, in conjunction with part 22 Cellular 
Radiotelephone licensees, shall establish an electronic means of 
receiving the initial notification described in paragraph (a)(1) of this 
section. The electronic system must be designed so that all appropriate 
800 MHz ESMR and part 22 Cellular Radiotelephone licensees can be 
contacted about the interference incident with a single notification. 
The electronic system for receipt of initial notification of 
interference complaints must be operating no later than February 22, 
2005.
    (3) ESMR licensees must respond to the initial notification 
described in paragraph (a)(1) of this section, as soon as possible and 
no later than 24 hours of receipt of notification from a public safety/
CII licensee. This response time may be extended to 48 hours after 
receipt from other non-cellular licensees provided affected 
communications on these systems are not safety related.
    (b) Interference analysis. ESMR licensees--who receive an initial 
notification described in paragraph (a) of this section--shall perform a 
timely analysis

[[Page 486]]

of the interference to identify the possible source. Immediate on-site 
visits may be conducted when necessary to complete timely analysis. 
Interference analysis must be completed and corrective action initiated 
within 48 hours of the initial complaint from a public safety/CII 
licensee. This response time may be extended to 96 hours after the 
initial complaint from other non-cellular licensees provided affected 
communications on these systems are not safety related. Corrective 
action may be delayed if the affected licensee agrees in writing (which 
may be, but is not required to be, recorded via e-mail or other 
electronic means) to a longer period.
    (c) Mitigation Steps. (1) All 800 MHz cellular system licensees and 
part 22 of this chapter Cellular Radiotelephone licensees who are 
responsible for causing unacceptable interference shall take all 
affirmative measures to resolve such interference. 800 MHz cellular 
system licensees found to contribute to harmful interference, as defined 
in Sec.  90.672, shall resolve such interference in the shortest time 
practicable. 800 MHz cellular system licensees and part 22 of this 
chapter Cellular Radiotelephone licensees must provide all necessary 
test apparatus and technical personnel skilled in the operation of such 
equipment as may be necessary to determine the most appropriate means of 
timely eliminating the interference. However, the means whereby 
interference is abated or the cell parameters that may need to be 
adjusted is left to the discretion of involved 800 MHz cellular system 
licensees and/or part 22 of this chapter Cellular Radiotelephone 
licensees, whose affirmative measures may include, but not be limited 
to, the following techniques:
    (i) Increasing the desired power of the public safety signal;
    (ii) Decreasing the power of the ESMR and/or part 22 Cellular 
Radiotelephone signal;
    (iii) Modifying the ESMR and/or part 22 Cellular Radiotelephone 
systems antenna height;
    (iv) Modifying the ESMR and/or part 22 Cellular Radiotelephone 
system antenna characteristics;
    (v) Incorporating filters into ESMR and/or part 22 Cellular 
Radiotelephone system transmission equipment;
    (vi) Permanently changing ESMR and/or part 22 Cellular 
Radiotelephone system frequencies; and
    (vii) Supplying interference-resistant receivers to the affected 
public safety licensee(s). If this technique is used, in all 
circumstances, the ESMR and/or part 22 Cellular Radiotelephone licensees 
shall be responsible for all costs thereof.
    (2) Whenever short-term interference abatement measures prove 
inadequate, the affected licensee shall, consistent with but not 
compromising safety, make all necessary concessions to accepting 
interference until a longer-term remedy can be implemented.
    (3) Discontinuing operations when clear and imminent danger exists. 
When a public safety licensee determines that a continuing presence of 
interference constitutes a clear and imminent danger to life or 
property, the licensee causing the interference must discontinue the 
associated operation immediately, until a remedy can be identified and 
applied. The determination that a continuing presence exists that 
constitutes a clear and imminent danger to life or property, must be 
made by written statement that:
    (i) Is in the form of a declaration, notarized affidavit, or 
statement under penalty or perjury, from an officer or executive of the 
affected public safety licensee;
    (ii) Thoroughly describes the basis of the claim of clear and 
imminent danger;
    (iii) Was formulated on the basis of either personal knowledge or 
belief after due diligence;
    (iv) Is not proffered by a contractor or other third party; and
    (v) Has been approved by the Chief of the Public Safety and Homeland 
Security Bureau or other designated Commission official. Prior to the 
authorized official making a determination that a clear and imminent 
danger exists, the associated written statement must be served by hand-
delivery or receipted fax on the applicable offending licensee, with a 
copy transmitted by the fastest available means to the

[[Page 487]]

Washington, DC office of the Commission's Public Safety and Homeland 
Security Bureau.

[69 FR 67849, Nov. 22, 2004, as amended at 70 FR 76711, Dec. 28, 2005; 
71 FR 69038, Nov. 29, 2006]



Sec.  90.675  Information exchange.

    (a) Prior coordination. Public safety/CII licensees may notify an 
ESMR or part 22 Cellular Radiotelephone licensee that they wish to 
receive prior notification of the activation or modification of ESMR or 
part 22 Cellular Radiotelephone cell sites in their area. Thereafter, 
the ESMR or part 22 Cellular Radiotelephone licensee must provide the 
following information to the public safety/CII licensee at least 10 
business days before a new cell site is activated or an existing cell 
site is modified:
    (1) Location;
    (2) Effective radiated power;
    (3) Antenna height;
    (4) Channels available for use.
    (b) Purpose of prior coordination. The coordination of cell sites is 
for informational purposes only: public safety/CII licensees are not 
afforded the right to accept or reject the activation of a proposed cell 
or to unilaterally require changes in its operating parameters. The 
principal purposes of notification are to:
    (1) Allow a public safety/CII licensee to advise the ESMR or part 22 
Cellular Radiotelephone licensee whether it believes a proposed cell 
will generate unacceptable interference;
    (2) Permit ESMR or part 22 Cellular Radiotelephone licensees to make 
voluntary changes in cell parameters when a public safety licensee 
alerts them to possible interference; and
    (3) Rapidly identify the source if interference is encountered when 
the cell is activated.
    (c) Public safety information exchange. (1) Upon request by an ESMR 
or part 22 Cellular Radiotelephone licensee, public safety/CII licensees 
who operate radio systems in the 806-824/851-869 MHz shall provide the

Sec.  90.683  EA-based SMR system operations.

    (a) EA-based licensees authorized in the 809-824/854-869 MHz band 
pursuant to Sec.  90.681 of this part may construct and operate base 
stations using any of the base station frequencies identified in their 
spectrum block anywhere within their authorized EA, provided that:
    (1) The EA licensee affords protection, in accordance with Sec.  
90.621(b), to all previously authorized co-channel stations that are not 
associated with another EA license;
    (2) The EA licensee complies with any rules and international 
agreements that restrict use of frequencies identified in their spectrum 
block, including the provisions of Sec.  90.619 relating to U.S./
Canadian and U.S./Mexican border areas;
    (3) The EA licensee limits the field strength of its base stations 
at any location on the border of the EA service area in accordance with 
Sec.  90.689;
    (4) Upon request by an incumbent licensee or the Commission, the EA 
licensees shall furnish the technical parameters, location and 
coordinates of the completion of the addition, removal, relocation or 
modification of any of its facilities within the EA. The EA licensee 
must provide such information within ten (10) days of receiving a 
written request.
    (5) For any construction or alteration that would exceed the 
requirements of Sec.  17.7 of this chapter, licensees

    (6) Any additional transmitters placed in operation must not have a 
significant environmental effect as defined by Sec. Sec.  1.1301 through 
1.1319 of this chapter.
    (b) In the event that the authorization for a previously authorized 
co-channel station within the EA licensee's spectrum block is terminated 
or revoked, the EA licensee's co-channel obligations to such station 
will cease upon deletion of the facility from the Commission's official 
licensing records, and the EA licensee then will be able to construct 
and operate without regard to that previous authorization.

Sec.  90.685  Authorization, construction and implementation of EA licenses.

    (a) EA licenses in the 809-824/854-869 MHz band will be issued for a 
term not to exceed ten years.
    (b) EA licensees in the 809-824/854-869 MHz band must, within three 
years of the grant of their initial license, construct and place into 
operation a sufficient number of base stations to provide coverage to at 
least one-third of the population of its EA-based service area. Further, 
each EA licensee must provide coverage to at least two-thirds of the 
population of the EA-based service area within five years of the grant 
of their initial license. EA-based licensees may, in the alternative, 
provide substantial service to their markets within five years of the 
grant of their initial license. Substantial service shall be defined as: 
``Service which is sound, favorable, and substantially above a level of 
mediocre service.''
    (c) Channel use requirement. In addition to the population coverage 
requirements described in this section, we will require EA licensees in 
Channel blocks A, B and C in the 816-821/861-866 MHz band to construct 
50 percent of the total channels included in their spectrum block in at 
least one location in their respective EA-based service area within 
three years of initial license grant and to retain such channel usage 
for the remainder of the construction period.
    (d) An EA licensee's failure to meet the population coverage 
requirements of paragraphs (b) and (c) of this section, will result in 
forfeiture of the entire EA license. Forfeiture of the EA license, 
however, would not result in the loss of any constructed facilities 
authorized to the licensee prior to the date of the commencement of the 
auction for the EA licenses.
    (e) EA licensees operating on channels listed in Sec.  90.614(b) and 
(c) must implement an Enhanced Specialized Mobile Radio (ESMR) system--
as defined in Sec.  90.7--on their EA license and any associated site-
based licenses prior to the expiration date of the EA license. EA 
licensees operating on these channels shall follow the construction 
notification procedures set forth in Sec.  1.946(d) of this chapter. 
Failure to implement an ESMR system on their EA and site-based licenses 
before the expiration date of the EA license will result in termination 
of the EA license and any associated site-based licenses pursuant to 
Sec.  1.946(c) of this chapter.

Sec.  90.687  Special provisions regarding assignments and transfers 
of authorizations for incumbent SMR licensees in the 809-824/854-869 MHz band.

    An SMR license initially authorized on any of the channels listed in 
Tables 4 and 5 of Sec.  90.617 may transfer or assign its channel(s) to 
another entity subject to the provisions of Sec.  1.948 of this chapter 
and Sec.  90.609(b). If the proposed transferee or assignee is the EA 
licensee for the spectrum block to which the channel is allocated, such 
transfer or assignment presumptively will be deemed to be in the public 
interest. However, such presumption will be rebuttable.

Sec.  90.689  Field strength limits.

    (a) For purposes of implementing Sec. Sec.  90.689 through 90.699, 
predicted 36 and 40 dB[micro]V/m contours shall be calculated using 
Figure 10 of Sec.  73.699 of this chapter with a correction factor of -9 
dB, and predicted 18 and 22 dB[micro]V/m contours shall be calculated 
using Figure 10a of Sec.  73.699 of this chapter with a correction 
factor of -9 dB.
    (b) The predicted or measured field strength at any location on the 
border of the EA-based service area for EA licensees must not exceed 40 
dBuV/m unless all bordering EA licensees agree to a higher field 
strength. In the event that this standard conflicts with the EA 
licensee's obligation to provide co-channel protection to incumbent 
licensees pursuant to Sec.  90.621(b), the requirements of Sec.  
90.621(b) shall prevail.

Sec.  90.691  Emission mask requirements for EA-based systems.

    (a) Out-of-band emission requirement shall apply only to the 
``outer'' channels included in an EA license and to spectrum adjacent to 
interior channels used by incumbent licensees. The emission limits are 
as follows:
    (1) For any frequency removed from the EA licensee's frequency block 
by up to and including 37.5 kHz, the power of any emission shall be 
attenuated below the transmitter power (P) in watts by at least 116 
Log10(f/6.1) decibels or 50 + 10 Log10(P) decibels 
or 80 decibels, whichever is the lesser attenuation, where f is the 
frequency removed from the center of the outer channel in the block in 
kilohertz and where f is greater than 12.5 kHz.
    (2) For any frequency removed from the EA licensee's frequency block 
greater than 37.5 kHz, the power of any emission shall be attenuated 
below the transmitter power (P) in watts by at least 43 + 
10Log10(P) decibels or 80 decibels, whichever is the lesser 
attenuation, where f is the frequency removed from the center of the 
outer channel in the block in kilohertz and where f is greater than 37.5 
kHz.
    (b) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.



Sec.  90.693  Grandfathering provisions for incumbent licensees.

    (a) General provisions. These provisions apply to ``incumbent 
licensees,'' all 800 MHz licensees authorized in the 809-821/854-866 MHz 
band who obtained licenses or filed applications on or before December 
15, 1995.
    (b) Spectrum blocks A through V. An incumbent licensee's service 
area shall be defined by its originally licensed 40 dB[mu]V/m field 
strength contour and its interference contour shall be defined as its 
originally-licensed 22 dB[mu]V/m field strength contour. The 
``originally-licensed'' contour shall be calculated using the maximum 
ERP and the actual height of the antenna above average terrain (HAAT) 
along each radial. Incumbent licensees are permitted to add, remove or 
modify transmitter sites within their original 22 dB[mu]V/m field 
strength contour without prior notification to the Commission so long as 
their original 22 dB[mu]V/m field strength contour is not expanded. 
Incumbent licensee protection extends only to its 40 dB[mu]V/m signal 
strength contour. Pursuant to the minor modification notification 
procedures set forth in 1.947(b), the incumbent licensee must notify the 
Commission within 30 days of any change in technical parameters for 
stations that are authorized under a waiver of 90.621(b)(4), or that are 
authorized under 90.621(b)(5).
    (c) Special provisions for spectrum blocks F1 through V. Incumbent 
licensees that have received the consent of all affected parties or a 
certified frequency coordinator to utilize an 18 dB[mu]V/m signal 
strength interference contour shall have their service area defined by 
their originally-licensed 36 dB[mu]V/m field strength contour and their 
interference contour shall be defined as their originally-licensed 18 
dB[mu]V/m field strength contour. The ``originally-licensed'' contour 
shall be calculated using the maximum ERP and the actual HAAT along each 
radial. Incumbent licensees seeking to utilize an 18 dB[mu]V/m signal 
strength interference contour shall first seek to

[[Page 490]]

obtain the consent of affected co-channel incumbents. When the consent 
of a co-channel licensee is withheld, an incumbent licensee may submit 
to any certified frequency coordinator an engineering study showing that 
interference will not occur, together with proof that the incumbent 
licensee has sought consent. Incumbent licensees are permitted to add, 
remove or modify transmitter sites within their original 18 dB[mu]V/m 
field strength contour without prior notification to the Commission so 
long as their original 18 dB[mu]V/m field strength contour is not 
expanded. Incumbent licensee protection extends only to its 36 dB[mu]V/m 
signal strength contour. Pursuant to the minor modification notification 
procedures set forth in 1.947(b), the incumbent licensee must notify the 
Commission within 30 days of any change in technical parameters for 
stations that are authorized under a waiver of 90.621(b)(4), or that are 
authorized under 90.621(b)(5).
    (d) Consolidated license--(1) Spectrum blocks A through V. Incumbent 
licensees operating at multiple sites may, after grant of EA licenses 
has been completed, exchange multiple site licenses for a single 
license, authorizing operations throughout the contiguous and 
overlapping 40 dB[micro]V/m field strength contours of the multiple 
sites. Incumbents exercising this license exchange option must submit 
specific information on Form 601 for each of their external base sites 
after the close of the 800 MHz SMR auction. The incumbent's geographic 
license area is defined by the contiguous and overlapping 22 dB[micro]V/
m contours of its constructed and operational external base stations and 
interior sites that are constructed within the construction period 
applicable to the incumbent. Once the geographic license is issued, 
facilities that are added within an incumbent's existing footprint and 
that are not subject to prior approval by the Commission will not be 
subject to construction requirements.
    (2) Special Provisions for Spectrum Blocks F1 through V. Incumbent 
licensees that have received the consent of all affected parties or a 
certified frequency coordinator to utilize an 18 dB[micro]V/m signal 
strength interference contour operating at multiple sites may, after 
grant of EA licenses has been completed, exchange multiple site licenses 
for a single license. This single site license will authorize operations 
throughout the contiguous and overlapping 36 dB[micro]V/m field strength 
contours of the multiple sites. Incumbents exercising this license 
exchange option must submit specific information on Form 601 for each of 
their external base sites after the close of the 800 SMR auction. The 
incumbent's geographic license area is defined by the contiguous and 
overlapping 18 dB[micro]V/m contours of its constructed and operational 
external base stations and interior sites that are constructed within 
the construction period applicable to the incumbent. Once the geographic 
license is issued, facilities that are added within an incumbent's 
existing footprint and that are not subject to prior approval by the 
Commission will not be subject to construction requirements.

Sec.  90.699  Transition of the upper 200 channels in the 800 MHz band 
to EA licensing.

    In order to facilitate provision of service throughout an EA, an EA 
licensee may relocate incumbent licensees in its EA by providing 
``comparable facilities'' on other frequencies in the 800 MHz band. Such 
relocation is subject to the following provisions:
    (a)-(c) [Reserved]
    (d) Comparable facilities. The replacement system provided to an 
incumbent during an involuntary relocation must be at least equivalent 
to the existing 800 MHz system with respect to the following four 
factors:
    (1) System. System is defined functionally from the end user's point 
of view (i.e., a system is comprised of base station facilities that 
operate on an integrated basis to provide service to a common end user, 
and all mobile units associated with those base stations). A system may 
include multiple-licensed facilities that share a common switch or are 
otherwise operated as a unitary system, provided that the end user has 
the ability to access all such facilities.

[[Page 491]]

A system may cover more than one EA if its existing geographic coverage 
extends beyond the EA borders.
    (2) Capacity. To meet the comparable facilities requirement, an EA 
licensee must relocate the incumbent to facilities that provide 
equivalent channel capacity. We define channel capacity as the same 
number of channels with the same bandwidth that is currently available 
to the end user. For example, if an incumbent's system consists of five 
50 kHz (two 25 kHz paired frequencies) channels, the replacement system 
must also have five 50 kHz channels. If a different channel 
configuration is used, it must have the same overall capacity as the 
original configuration. Comparable channel capacity requires equivalent 
signaling capability, baud rate, and access time. In addition, the 
geographic coverage of the channels must be coextensive with that of the 
original system.
    (3) Quality of service. Comparable facilities must provide the same 
quality of service as the facilities being replaced. Quality of service 
is defined to mean that the end user enjoys the same level of 
interference protection on the new system as on the old system. In 
addition, where voice service is provided, the voice quality on the new 
system must be equal to the current system. Finally, reliability of 
service is considered to be integral to defining quality of service. 
Reliability is the degree to which information is transferred accurately 
within the system. Reliability is a function of equipment failures 
(e.g., transmitters, feed lines, antennas, receivers, battery back-up 
power, etc.) and the availability of the frequency channel due to 
propagation characteristics (e.g., frequency, terrain, atmospheric 
conditions, radio-frequency noise, etc.) For digital data systems, this 
will be measured by the percent of time the bit error rate exceeds the 
desired value. For analog or digital voice transmissions, this will be 
measured by the percent of time that audio signal quality meets an 
established threshold. If analog voice system is replaced with a digital 
voice system the resulting frequency response, harmonic distortion, 
signal-to-noise ratio, and reliability will be considered.
    (4) Operating costs. Operating costs are those costs that affect the 
delivery of services to the end user. If the EA licensee provides 
facilities that entail higher operating cost than the incumbent's 
previous system, and the cost increase is a direct result of the 
relocation, the EA licensee must compensate the incumbent for the 
difference. Costs associated with the relocation process can fall into 
several categories. First, the incumbent must be compensated for any 
increased recurring costs associated with the replacement facilitates 
(e.g., additional rental payments, increased utility fees). Second, 
increased maintenance costs must be taken into consideration when 
determining whether operating costs are comparable. For example, 
maintenance costs associated with analog systems may be higher than the 
costs of digital equipment because manufacturers are producing mostly 
digital equipment and analog replacement parts can be difficult to find. 
An EA licensee's obligation to pay increased operating costs will end 
five years after relocation has occurred.

Sec.  90.711  Processing of Phase II applications.

    (a) Phase II applications for authorizations on Channels 166 through 
170 and Channels 181 through 185 will be processed on a first-come, 
first-served basis. When multiple applications are filed on the same day 
for these frequencies in the same geographic area, and insufficient 
frequencies are available to grant all applications (i.e., if all 
applications were granted, violation of the station separation 
provisions of Sec.  90.723(k) of this part would result), these 
applications will be considered mutually exclusive.
    (1) All applications will first be considered to determine whether 
they are substantially complete and acceptable for filing. If so, they 
will be assigned a file number and put in pending status. If not, they 
will be dismissed.
    (2) Except as otherwise provided in this section, all applications 
in pending status will be processed in the order in which they are 
received, determined by the date on which the application was received 
by the Commission in its Gettysburg, Pennsylvania office (or the address 
set forth at Sec.  1.1102 of this chapter for applications requiring the 
fees established by part 1, subpart G of this chapter).
    (3) Each application that is accepted for filing will then be 
reviewed to determine whether it can be granted. Frequencies will be 
assigned by the Commission pursuant to the provisions of Sec.  90.723.
    (4) An application which is dismissed will lose its place in the 
processing line.
    (b) All applications for Channels 161 through 165 that comply with 
the applicable rules of this part shall be granted. Licensees operating 
on such channels shall cooperate in the selection and use of frequencies 
and resolve any instances of interference in accordance with the 
provisions of Sec.  90.173.
    (c) Phase II applications for authorization on all non-Government 
channels other than Channels 161 through 170 and 181 through 185 shall 
be processed in accordance with the provisions of subpart W of this 
part.

    (c) An applicant relying on personal or internal resources for the 
showing required in paragraph (b) of this section must submit 
independently audited financial statements certified within one year of 
the date of the application showing net current assets sufficient to 
meet estimated construction and operating costs. An applicant must also 
submit an unaudited balance sheet, current within 60 days of the date of 
submission, that clearly shows the continued availability of sufficient 
net current assets to construct and operate the proposed system, and a 
certification by the applicant or an officer of the applicant 
organization attesting to the validity of the balance sheet.
    (d) An applicant submitting evidence of a firm financial commitment 
for the showing required in paragraph (b) of this section must obtain 
the commitment from a bona fide commercially acceptable source, e.g., a 
state or federally chartered bank or savings and loan institution, other 
recognized financial institution, the financial arm of a capital 
equipment supplier, or an investment banking house. If the lender is not 
a state or federally chartered bank or savings and loan institution, 
other recognized financial institution, the financial arm of a capital 
equipment supplier, or an investment banking house, the lender must also 
demonstrate that it has funds available to cover the total commitments 
it has made. The lender's commitment shall contain a statement that the 
lender:
    (1) Has examined the financial condition of the applicant including 
an audited financial statement, and has determined that the applicant is 
creditworthy;
    (2) Has examined the financial viability of the proposed system for 
which the applicant intends to use the commitment; and
    (3) Is willing, if the applicant is seeking a Phase I, commercial 
nationwide license, to provide a sum to the applicant sufficient to 
cover the realistic and prudent estimated costs of construction of 40 
percent of the system and operation of the system for the first four 
years of the license term.
    (e) A Phase II applicant for authorization in a geographic area for 
Channels 166 through 170 in the public safety/mutual aid category may 
not have any interest in another pending application in the same 
geographic area for Channels 166 through 170 in the public safety/mutual 
aid category, and a Phase II applicant for authorization in a geographic 
area for channels in the emergency medical category may not have any 
interest in another pending application in the same geographic area for 
channels in the emergency medical category.

the emission limits in Sec.  90.210(f) must be met only at the outermost 
edges of the contiguous channels. Transmitters shall be tested to 
confirm compliance with this requirement with the transmission located 
as close to the band edges as permitted by the design of the 
transmitter. The frequency stability requirements in Sec.  90.213 shall 
apply only to the outermost of the contiguous channels authorized to the 
licensee. However, the frequency stability employed for transmissions 
operating inside the outermost contiguous channels must be such that the 
emission limits in Sec.  90.210(f) are met over the temperature and 
voltage variations prescribed in Sec.  2.995 of this chapter.
    (f) A Phase I non-nationwide licensee operating a paging base 
station, or a fixed station transmitting on frequencies in the 220-221 
MHz band, may only operate such stations at the coordinates of the 
licensee's authorized land mobile base station.
    (g) The transmissions of a Phase I non-nationwide licensee's paging 
base station, or fixed station transmitting on frequencies in the 220-
221 MHz band, must meet the requirements of Sec. Sec.  90.723(d), (g), 
(h), and (k), and 90.729, and such a station must operate at the 
effective radiated power and antenna height-above-average-terrain 
prescribed in the licensee's land mobile base station authorization.
    (h) Licensees using 220-222 MHz spectrum for geophysical telemetry 
operations are authorized to operate fixed stations on a secondary, non-
interference basis to licensees operating in the 220-222 MHz band on a 
primary basis under the conditions that such licensees:
    (1) Provide notification of their operations to co-channel non-
nationwide Phase I licensees with an authorized base station, or fixed 
station transmitting on frequencies in the 220-221 MHz band, located 
within 45 km of the secondary licensee's station, to co-channel, Phase 
II EA or Regional licensee authorized to operate in the EA or REAG in 
which the secondary licensee's station is located, and to co-channel 
Phase I or Phase II nationwide licensees;
    (2) Operate only at temporary locations in accordance with the 
provisions of Sec.  1.931 of this chapter;
    (3) Not transmit at a power level greater than one watt ERP;

[[Page 503]]

    (4) Not transmit from an antenna higher than 2 meters (6.6 feet) 
above ground; and
    (5) Not operate on Channels 111 through 120, 161 through 170, or 181 
through 185.
    (i) All licensees constructing and operating base stations or fixed 
stations on frequencies in the 220-222 MHz band must:
    (1) Comply with any rules and international agreements that restrict 
use of their authorized frequencies, including the provisions of Sec.  
90.715 relating to U.S./Mexican border areas;
    (2) Comply with the provisions of Sec.  17.6 of this chapter with 
regard to antenna structures; and
    (3) Comply with the provisions of Sec. Sec.  1.1301 through 1.1319 
of this chapter with regard to actions that may or will have a 
significant impact on the quality of the human environment.

Sec.  90.735  Station identification.

    (a) Except for nationwide systems authorized in the 220-222 MHz 
band, station identification is required pursuant to Sec.  90.425 of 
this part.
    (b) Trunked systems shall employ an automatic device to transmit the 
call sign of the base station at 30 minute intervals. The identification 
shall be made on the lowest frequency in the base station trunked group 
assigned to the licensee. If this frequency is in use at the time 
identification is required, the identification may be made at the 
termination of the communication in progress on this frequency.
    (c) Station identification may be by voice or International Morse 
Code. If the call sign is transmitted in International Morse Code, it 
must be at a rate of between 15 to 20 words per minute, and by means of 
tone modulation of the transmitter, with the tone frequency being 
between 800 and 1000 hertz.
    (d) Digital transmissions may also be identified by digital 
transmission of the station call sign. A licensee that identifies its 
station in this manner must provide the Commission, upon its request, 
information (such as digital codes and algorithms) sufficient to 
decipher the data transmission to ascertain the call sign transmitted.

Sec.  90.739  Number of systems authorized in a geographical area.

    There is no limit on the number of licenses that may be authorized 
to a single licensee.

Sec.  90.741  Urban areas for Phase I nationwide systems.

    Licensees of Phase I nationwide systems must construct base 
stations, or fixed stations transmitting on frequencies in the 220-221 
MHz band, in a minimum of 28 of the urban areas listed in the following 
Table within ten years of initial license grant. A base station, or 
fixed station, is considered to be within one of the listed urban areas 
if it is within 60 kilometers (37.3 miles) of the specified coordinates 
(coordinates are referenced to North American Datum 1983 (NAD83)).

chapter. Licensees must demonstrate, in their application, that:
    (a) They have provided ``substantial'' service during their past 
license term. ``Substantial'' service is defined in this rule as service 
that is sound, favorable, and substantially above a level of mediocre 
service that just might minimally warrant renewal; and
    (b) They have substantially complied with applicable FCC rules, 
policies, and the Communications Act of 1934, as amended.

Sec.  90.745  Phase I licensee service areas.

    (a) A Phase I licensee's service area shall be defined by the 
predicted 38 dBu service contour of its authorized base station or fixed 
station transmitting on frequencies in the 220-221 MHz band at its 
initially authorized location or at the location authorized in 
accordance with Sec. Sec.  90.751, 90.753, 90.755 and 90.757 if the 
licensee has sought modification of its license to relocate its 
initially authorized base station. The Phase I licensee's predicted 38 
dBu service contour is calculated using the F(50,50) field strength 
chart for Channels 7-13 in Sec.  73.699 (Fig. 10) of this chapter, with 
a 9 dB correction factor for antenna height differential, and is based 
on the authorized effective radiated power (ERP) and antenna height-
above-average-terrain of the licensee's base station or fixed station. 
Phase I licensees are permitted to add, remove, or modify transmitter 
sites within their existing service area without prior notification to 
the Commission so long as their predicted 38 dBu service contour is not 
expanded. The incumbent licensee must, however, notify the Commission 
within 30 days of the completion of any changes in technical parameters 
or additional stations constructed through a minor modification of its 
license. Such notification must be made by submitting the appropriate 
FCC form and must include the appropriate filing fee, if any. These 
minor modification applications are not subject to public notice and 
petition to deny requirements or mutually exclusive applications.
    (b) Phase I licensees holding authorizations for service areas that 
are contiguous and overlapping may exchange these authorizations for a 
single license, authorizing operations throughout the contiguous and 
overlapping service areas. Phase I licensees exercising this license 
exchange option must submit specific information for

[[Page 506]]

each of their external base station sites.

Sec.  90.751  Minor modifications of Phase I, non-nationwide licenses.

    Phase I non-nationwide licensees will be given an opportunity to 
seek modification of their license to relocate their initially 
authorized base station, i.e., locate their base station at a site other 
than its initially authorized location. The conditions under which 
modifications will be granted and the procedures for applying for 
license modifications are described in Sec. Sec.  90.753, 90.757 and 
1.929 of this chapter. For CMRS licensees, these modifications will be 
treated as minor modifications in accordance with Sec.  1.929 of this 
chapter.

[63 FR 68973, Dec. 14, 1998]



Sec.  90.753  Conditions of license modification.

    (a) Except as provided in paragraphs (b), and (c) of this section, a 
Phase I non nationwide licensee may modify its authorization to relocate 
its authorized base station up to one-half the distance over 120 km 
toward any co-channel licensee's initially authorized base station, to a 
maximum distance of 8 km.
    (b) A Phase I non-nationwide licensee with an authorized base 
station located outside a Designated Filing Area (DFA) (see Public 
Notice, DA 86-173, 52 FR 1302 (January 12, 1987)) may modify its 
authorization to relocate its authorized base station up to one-half the 
distance over 120 km toward any co-channel licensee's initially 
authorized base station, to a maximum distance of 25 km, so long as the 
base station is relocated no more than 8 km inside of any DFA (i.e., no 
more than 8 km from the nearest DFA boundary line).
    (c) A Phase I non-nationwide licensee that has been granted Special 
Temporary Authority (STA) to operate at an alternative base station 
location may modify its authorization to seek permanent authorization at 
that location, regardless of whether locating the station at the STA 
site is in strict conformance with the provisions of paragraphs (a) and 
(b) of this section, if the licensee certifies that such a modification 
is in conformance with Sec. Sec.  90.723 and 90.729 and:
    (1) It has constructed its base station and has placed it in 
operation, or commenced service, at the STA site on or before January 
26, 1996; or
    (2) It has taken delivery of its base station transceiver on or 
before January 26, 1996.
    (d) The application for a Phase I non-nationwide licensee proposing 
a base station modification resulting in less than 120 km separation 
from a co-channel licensee's initially authorized base station will be 
accepted by the Commission only with the consent of that co-channel 
licensee, as evidenced in a statement submitted concurrently with the 
licensee's application submission on FCC Form 601.
    (e) The application of a Phase I non-nationwide licensee proposing a 
base station modification resulting in at least a 120 km separation from 
each co-channel licensee's initially authorized base station but more 
than one-half the distance over 120 km toward any co-channel licensee's 
initially authorized base station will be accepted by the Commission 
only with the consent of that co-channel licensee, as evidenced in a 
statement submitted concurrently with the licensee's submission on FCC 
Form 601.

Sec.  90.757  Construction requirements.

    (a) Except as provided in paragraph (b) of this section, a Phase I 
non-nationwide licensee that is granted modification of its 
authorization to relocate its base station must construct its base 
station and place it in operation, or commence service, on all 
authorized channels on or before August 15, 1996, or within 12 months of 
initial grant date, whichever is later. The authorization of a licensee 
that does not construct its base station and place it in operation, or 
commence service, by this date, cancels automatically and must be 
returned to the Commission.
    (b) A Phase I non-nationwide licensee with a base station authorized 
at a location north of Line A must construct its base station and place 
it in operation, or commence service, on all authorized channels within 
12 months of

[[Page 507]]

initial grant date, or within 12 months of the date of the release of 
the terms of an agreement between the United States and Canadian 
governments on the sharing of 220-222 MHz spectrum between the two 
countries, whichever is later. The authorization of a licensee that does 
not construct its base station and place it in operation, or commence 
service, by this date, cancels automatically and must be returned to the 
Commission.

    (a) A nationwide licensee authorized pursuant to Sec.  90.717(a) may 
construct and operate any number of land mobile or paging base stations, 
or fixed stations, anywhere in the Nation, and transmit on any of its 
authorized channels, provided that the licensee complies with the 
requirements of Sec.  90.733(i).
    (b) An EA or Regional licensee authorized pursuant to Sec.  90.761 
may construct and operate any number of land mobile or paging base 
stations, or fixed stations, anywhere within its authorized EA or REAG, 
and transmit on any of its authorized channels, provided that:
    (1) The licensee affords protection to all authorized co-channel 
Phase I non-nationwide base stations as follows:
    (i) The EA or Regional licensee must locate its land mobile or 
paging base stations, or fixed stations transmitting on base station 
transmit frequencies, at least 120 km from the land mobile or paging 
base stations, or fixed stations transmitting on base station transmit 
frequencies, of co-channel Phase I licensees, except that separations of 
less than 120 km shall be considered on a case-by-case basis upon 
submission by the EA or Regional licensee of:
    (A) A technical analysis demonstrating at least 10 dB protection to 
the predicted 38 dBu service contour of the co-channel Phase I licensee, 
i.e., demonstrating that the predicted 28 dBu interfering contour of the 
EA or Regional licensee's base station or fixed station does not overlap 
the predicted 38 dBu service contour of the co-channel Phase I 
licensee's base station or fixed station; or
    (B) A written letter from the co-channel Phase I licensee consenting 
to a separation of less than 120 km, or to less than 10 dB protection to 
the predicted 38 dBu service contour of the licensee's base station or 
fixed station.
    (ii) The Phase I licensee's predicted 38 dBu service contour 
referred to in paragraph (a)(1)(i) of this section is calculated using 
the F(50,50) field strength chart for Channels 7-13 in Sec.  73.699 
(Fig. 10) of this chapter, with a 9 dB correction factor for antenna 
height differential, and is based on the licensee's authorized effective 
radiated power and antenna height-above-average-terrain. The EA or 
Regional licensee's predicted 28 dBu interfering contour referred to in 
paragraph (a)(1)(i) of this section is calculated using the F(50,10) 
field strength chart for Channels 7-13 in Sec.  73.699 (Fig. 10a) of 
this chapter, with a 9 dB correction factor for antenna height 
differential.
    (2) The licensee complies with the requirements of Sec.  90.733(i).
    (3) The licensee limits the field strength of its base stations, or 
fixed stations operating on base station transmit frequencies, in 
accordance with the provisions of Sec.  90.771.
    (4) Upon request by a licensee or the Commission, an EA or regional 
licensee shall furnish the technical parameters, location and 
coordinates of the completion of the addition, removal, relocation or 
modification of any of its facilities within the EA or region. The EA or 
regional licensee must provide such information within

[[Page 508]]

ten (10) days of receiving written notification.
    (c) In the event that the authorization for a co-channel Phase I 
base station, or fixed station transmitting on base station transmit 
frequencies, within an EA or Regional licensee's border is terminated or 
revoked, the EA or Regional licensee's channel obligations to such 
stations will cease upon deletion of the facility from the Commission's 
official licensing records, and the EA or Regional licensee then will be 
able to construct and operate without regard to the previous 
authorization.

Sec.  90.812  [Reserved]



Sec.  90.813  Partitioned licenses and disaggregated spectrum.

    (a) Eligibility. Parties seeking approval for partitioning and 
disaggregation shall request an authorization for partial assignment of 
a license pursuant to Sec.  1.948 of this chapter.
    (b) Technical standards--(1) Partitioning. In the case of 
partitioning, requests for authorization for partial assignment of a 
license must include, as attachments, a description of the partitioned 
service area and a calculation of the population of the partitioned 
service area and the licensed geographic service area. The partitioned 
service area shall be defined by coordinate points at every 3 degrees 
along the partitioned service area unless an FCC recognized service area 
is utilized (i.e., Major Trading Area, Basic Trading Area, Metropolitan 
Service Area, Rural Service Area or Economic Area) or county lines are 
followed. The geographic coordinates must be specified in degrees, 
minutes, and seconds to the nearest second of latitude and longitude and 
must be based upon the 1927 North American Datum (NAD27). Applicants may 
supply geographical coordinates based on 1983 North American Datum 
(NAD83) in addition to those required (NAD27). In the case where an FCC 
recognized service area or county lines are utilized, applicants need 
only list the specific area(s) (through use of FCC designations or 
county names) that constitute the partitioned area.
    (2) Disaggregation. Spectrum may be disaggregated in any amount.
    (3) Combined partitioning and disaggregation. The Commission will 
consider requests for partial assignment of licenses that propose 
combinations of partitioning and disaggregation.
    (c) Installment payments--(1) Apportioning the balance on 
installment payment plans. When a winning bidder elects to pay for its 
license through an installment payment plan pursuant to Sec.  90.812, 
and partitions its licensed area or disaggregates spectrum to another 
party, the outstanding balance owed by the licensee on its installment 
payment plan (including accrued and unpaid interest) shall be 
apportioned between the licensee and partitionee or disaggregatee. Both 
parties will be responsible for paying their proportionate share of the 
outstanding balance to the U.S. Treasury. In the case of partitioning, 
the balance shall be apportioned based upon the ratio of the population 
of the partitioned area to the population of the entire original license 
area calculated based upon the most recent census data. In the case of 
disaggregation, the balance shall be apportioned based upon the ratio of 
the amount of spectrum disaggregated to the amount of spectrum allocated 
to the licensed area.
    (2) Parties not qualified for installment payment plans. (i) The 
partitionee or disaggregatee shall, as a condition of the approval of 
the partial assignment application, pay its entire pro rata amount 
within 30 days of Public Notice conditionally granting the partial 
assignment application. Failure to meet this condition will result in a 
rescission of the grant of the partial assignment application.
    (ii) The licensee shall be permitted to continue to pay its pro rata 
share of the outstanding balance and shall receive new financing 
documents (promissory note, security agreement) with a revised payment 
obligation, based on the remaining amount of time on the original 
installment payment schedule. These financing documents will replace the 
licensee's existing financing documents which shall be marked 
``superseded'' and returned to the licensee upon receipt of the new 
financing documents. The original interest rate, established pursuant to 
Sec.  1.2110(g)(3)(i) of this chapter at the time of the grant of the 
initial license in the market, shall continue to be applied to the 
licensee's portion of the remaining government obligation. The 
Commission will require, as a further condition to approval of the 
partial assignment application, that the licensee execute and return to 
the U.S. Treasury the new financing documents within 30 days of

[[Page 511]]

the Public Notice conditionally granting the partial assignment 
application. Failure to meet this condition will result in the automatic 
cancellation of the grant of the partial assignment application.
    (iii) A default on the licensee's payment obligation will only 
affect the licensee's portion of the market.
    (3) Parties qualified for installment payment plans. (i) Where both 
parties to a partitioning or disaggregation agreement qualify for 
installment payments, the partitionee or disaggregatee will be permitted 
to make installment payments on its portion of the remaining government 
obligation, as calculated according to paragraph (d)(1) of this section.
    (ii) Each party will be required, as a condition to approval of the 
partial assignment application, to execute separate financing documents 
(promissory note, security agreement) agreeing to pay their pro rata 
portion of the balance due (including accrued and unpaid interest) based 
upon the installment payment terms for which they qualify under the 
rules. The financing documents must be returned to the U.S. Treasury 
within thirty (30) days of the Public Notice conditionally granting the 
partial assignment application. Failure by either party to meet this 
condition will result in the automatic cancellation of the grant of the 
partial assignment application. The interest rate, established pursuant 
to Sec.  1.2110(g)(3)(i) of this chapter at the time of the grant of the 
initial license in the market, shall continue to be applied to both 
parties' portion of the balance due. Each party will receive a license 
for their portion of the partitioned market or disaggregated spectrum.
    (iii) A default on an obligation will only affect that portion of 
the market area held by the defaulting party.
    (iv) Partitionees and disaggregatees that qualify for installment 
payment plans may elect to pay some of their pro rata portion of the 
balance due in a lump sum payment to the U.S. Treasury and to pay the 
remaining portion of the balance due pursuant to an installment payment 
plan.
    (d) License term. The license term for a partitioned license area 
and for disaggregated spectrum shall be the remainder of the original 
licensee's license term as provided for in Sec.  90.665(a).

    (2) High power devices are also limited to a peak power spectral 
density of 21 dBm per one MHz. High power devices using channel 
bandwidths other than those listed above are permitted; however, they 
are limited to peak power spectral density of 21 dBm/MHz. If 
transmitting antennas of directional gain greater than 9 dBi are used, 
both the maximum conducted output power and the peak power spectral 
density should be reduced by the amount in decibels that the directional 
gain of the antenna exceeds 9 dBi. However, high power point-to-point 
and point-to-multipoint operations (both fixed and temporary-fixed rapid 
deployment) may employ transmitting antennas with directional gain up to 
26 dBi without any corresponding reduction in the maximum conducted 
output power or spectral density. Corresponding reduction in the maximum 
conducted output power and peak power spectral density should be the 
amount in decibels that the directional gain of the antenna exceeds 26 
dBi.
    (b) Low power devices are also limited to a peak power spectral 
density of 8 dBm per one MHz. Low power devices using channel bandwidths 
other than those listed above are permitted; however, they are limited 
to a peak power spectral density of 8 dBm/MHz. If transmitting antennas 
of directional gain greater than 9 dBi are used, both the maximum 
conducted output power and the peak power spectral density should be 
reduced by the amount in decibels that the directional gain of the 
antenna exceeds 9 dBi.

[[Page 519]]

    (c) The maximum conducted output power is measured as a conducted 
emission over any interval of continuous transmission using 
instrumentation calibrated in terms of an RMS-equivalent voltage. If the 
device cannot be connected directly, alternative techniques acceptable 
to the Commission may be used. The measurement results shall be properly 
adjusted for any instrument limitations, such as detector response 
times, limited resolution bandwidth capability when compared to the 
emission bandwidth, sensitivity, etc., so as to obtain a true maximum 
conducted output power measurement conforming to the definitions in this 
paragraph for the emission in question.
    (d) The peak power spectral density is measured as conducted 
emission by direct connection of a calibrated test instrument to the 
equipment under test. If the device cannot be connected directly, 
alternative techniques acceptable to the Commission may be used. 
Measurements are made over a bandwidth of one MHz or the 26 dB emission 
bandwidth of the device, whichever is less. A resolution bandwidth less 
than the measurement bandwidth can be used, provided that the measured 
power is integrated to show total power over the measurement bandwidth. 
If the resolution bandwidth is approximately equal to the measurement 
bandwidth, and much less than the emission bandwidth of the equipment 
under test, the measured results shall be corrected to account for any 
difference between the resolution bandwidth of the test instrument and 
its actual noise bandwidth.
    (e) The ratio of the peak excursion of the modulation envelope 
(measured using a peak hold function) to the maximum conducted output 
power shall not exceed 13 dB across any 1 MHz bandwidth or the emission 
bandwidth whichever is less.
    (f) The transmitting power of permanent fixed point-to-point and 
point-to-multipoint stations operating in the 4940-4990 MHz band must 
not exceed the maximum limits in this paragraph (f). Moreover, 
applicants should request no more power than necessary for a particular 
use.
    (1) The maximum equivalent isotropically radiated power (EIRP), as 
referenced to an isotropic radiator, must not exceed 55 dBW (85 dBm).
    (2) For path lengths shorter than 17 kilometers, the EIRP shall not 
exceed the value derived from the following equation: New EIRP limit = 
55 dBW--40*log(17/B) dBW, where B = the actual path length in 
kilometers.

     Subpart Z_Wireless Broadband Services in the 3650	3700 MHz Band

    Source: 70 FR 24726, May 11, 2005, unless otherwise noted.



Sec.  90.1301  Scope.

    This subpart sets out the regulations governing wireless operations 
in the 3650-3700 MHz band. It includes licensing requirements, and 
specific operational and technical standards for wireless operations in 
this band. The rules in this subpart are to be read in conjunction with 
the applicable requirements contained elsewhere in the Commission's 
rules; however, in case of conflict, the provisions of this subpart 
shall govern with respect to licensing and operation in this band.



Sec.  90.1303  Eligibility.

    Any entity, other than those precluded by section 310 of the 
Communications Act of 1934, as amended, 47 U.S.C. 310, is eligible to 
hold a license under this part.



Sec.  90.1305  Permissible operations.

    Use of the 3650-3700 MHz band must be consistent with the 
allocations for this band as set forth in part 2 of the

[[Page 520]]

Commission's Rules. All stations operating in this band must employ a 
contention-based protocol (as defined in Sec.  90.7).



Sec.  90.1307  Licensing.

    (a) The 3650-3700 MHz band is licensed on the basis of non-exclusive 
nationwide licenses. Non-exclusive nationwide licenses will serve as a 
prerequisite for registering individual fixed and base stations. A 
licensee cannot operate a fixed or base station before registering it 
under its license and licensees must delete registrations for unused 
fixed and base stations.
    (b) The Commission shall issue no new licenses or license renewals 
under this section after April 17, 2015, except as specified in 
paragraph (c) of this section.
    (c) If a license issued under this Section expires between April 17, 
2015 and April 17, 2020, the licensee may request a one-time renewal and 
the Commission may renew that license for a term ending no later than 
April 17, 2020.
    (d) Licenses that were issued after January 8, 2013 will be afforded 
protection from harmful interference from Citizens Broadband Radio 
Service users pursuant to Sec.  90.1338 until April 17, 2020 regardless 
of their expiration date.

[80 FR 36222, June 23, 2015]



Sec.  90.1309  Regulatory status.

    Licensees are permitted to provide services on a non-common carrier 
and/or on a common carrier basis. A licensee may render any kind of 
communications service consistent with the regulatory status in its 
license and with the Commission's rules applicable to that service.



Sec.  90.1311  License term.

    The license term is ten years, except as set forth in Sec.  90.1307, 
beginning on the date of the initial authorization (non-exclusive 
nationwide license) grant. Registering fixed and base stations will not 
change the overall renewal period of the license.

[80 FR 36222, June 23, 2015]



Sec.  90.1312  Assignment and transfer.

    Licensees may assign or transfer their non-exclusive nationwide 
licenses, and any fixed or base stations registered under those licenses 
will remain associated with those licenses.



Sec.  90.1319  Policies governing the use of the 3650-3700 MHz band.

    (a) Channels in this band are available on a shared basis only and 
will not be assigned for the exclusive use of any licensee.
    (b) Any base, fixed, or mobile station operating in the band must 
employ a contention-based protocol.
    (c) Equipment incorporating an unrestricted contention-based 
protocol (i.e. one capable of avoiding co-frequency interference with 
devices using all other types of contention-based protocols) may operate 
throughout the 50 megahertz of this frequency band. Equipment 
incorporating a restricted contention-based protocol (i.e. one that does 
not qualify as unrestricted) may operate in, and shall only tune over, 
the lower 25 megahertz of this frequency band.
    (d) All applicants and licensees shall cooperate in the selection 
and use of frequencies in the 3650-3700 MHz band in order to minimize 
the potential for interference and make the most effective use of the 
authorized facilities. A database identifying the locations of 
registered stations will be available at http://wireless.fcc.gov/uls. 
Licensees should examine this database before seeking station 
authorization, and make every effort to ensure that their fixed and base 
stations operate at a location, and with technical parameters, that will 
minimize the potential to cause and receive interference. Licensees of 
stations suffering or causing harmful interference are expected to 
cooperate and resolve this problem by mutually satisfactory 
arrangements.

[72 FR 40722, July 25, 2007]



Sec.  90.1321  Power and antenna limits.

    (a) Base and fixed stations are limited to 25 watts/25 MHz 
equivalent isotropically radiated power (EIRP). In any event, the peak 
EIRP power density shall not exceed 1 Watt in any one-megahertz slice of 
spectrum.
    (b) In addition to the provisions in paragraph (a) of this section, 
transmitters operating in the 3650-3700 MHz band that emit multiple 
directional

[[Page 521]]

beams, simultaneously or sequentially, for the purpose of directing 
signals to individual receivers or to groups of receivers provided the 
emissions comply with the following:
    (1) Different information must be transmitted to each receiver.
    (2) If the transmitter employs an antenna system that emits multiple 
directional beams but does not emit multiple directional beams 
simultaneously, the total output power conducted to the array or arrays 
that comprise the device, i.e., the sum of the power supplied to all 
antennas, antenna elements, staves, etc. and summed across all carriers 
or frequency channels, shall not exceed the limit specified in paragraph 
(a) of this section, as applicable. The directional antenna gain shall 
be computed as follows:
    (i) The directional gain, in dBi, shall be calculated as the sum of 
10 log (number of array elements or staves) plus the directional gain, 
in dBi, of the individual element or stave having the highest gain.
    (ii) A lower value for the directional gain than that calculated in 
paragraph (b)(2)(i) of this section will be accepted if sufficient 
evidence is presented, e.g., due to shading of the array or coherence 
loss in the beam-forming.
    (3) If a transmitter employs an antenna that operates simultaneously 
on multiple directional beams using the same or different frequency 
channels and if transmitted beams overlap, the power shall be reduced to 
ensure that the aggregate power from the overlapping beams does not 
exceed the limit specified in paragraph (b)(2) of this section. In 
addition, the aggregate power transmitted simultaneously on all beams 
shall not exceed the limit specified in paragraph (b)(2) of this section 
by more than 8 dB.
    (4) Transmitters that emit a single directional beam shall operate 
under the provisions of paragraph (b)(2) of this section.
    (c) Mobile and portable stations are limited to 1 watt/25 MHz EIRP. 
In any event, the peak EIRP density shall not exceed 40 milliwatts in 
any one-megahertz slice of spectrum.



Sec.  90.1323  Emission limits.

    (a) The power of any emission outside a licensee's frequency band(s) 
of operation shall be attenuated below the transmitter power (P) within 
the licensed band(s) of operation, measured in watts, by at least 43 + 
10 log (P) dB. Compliance with this provision is based on the use of 
measurement instrumentation employing a resolution bandwidth of 1 MHz or 
less, but at least one percent of the emission bandwidth of the 
fundamental emission of the transmitter, provided the measured energy is 
integrated over a 1 MHz bandwidth.
    (b) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.



Sec.  90.1331  Restrictions on the operation of base and fixed stations.

    (a)(1) Except as provided in paragraph (a)(2) of this section, base 
and fixed stations may not be located within 150 km of any grandfathered 
satellite earth station operating in the 3650-3700 MHz band. The 
coordinates of these stations are available at http://www.fcc.gov/ ib/
sd/ 3650/.
    (2) Base and fixed stations may be located within 150 km of a 
grandfathered satellite earth station provided that the licensee of the 
satellite earth station and the 3650-3700 MHz licensee mutually agree on 
such operation.
    (3) Any negotiations to enable base or fixed station operations 
closer than 150 km to grandfathered satellite earth stations must be 
conducted in good faith by all parties.
    (b)(1) Except as specified in paragraph (b)(2) of this section, base 
and fixed stations may not be located within 80 km of the following 
Federal Government radiolocation facilities:

St. Inigoes, MD--38[deg] 10[min] N., 76[deg], 23[min] W
Pensacola, FL--30[deg] 21[min] 28[sec] N., 87[deg], 16[min] 26[sec] W
Pascagoula, MS--30[deg] 22[min] N, 88[deg] 29[min]

    Note to paragraph (b)(1): Licensees installing equipment in the 
3650-3700 MHz band should determine if there are any nearby Federal 
Government radar systems that could affect their operations. Information 
regarding the location and operational characteristics of the radar 
systems operating adjacent to this band are provided in NTIA TR-99-361.


[[Page 522]]


    (2) Requests for base or fixed station locations closer than 80 km 
to the Federal Government radiolocation facilities listed in paragraph 
(b)(1) of this section will only be approved upon successful 
coordination by the Commission with NTIA through the Frequency 
Assignment Subcommittee of the Interdepartmental Radio Advisory 
Committee.

[70 FR 24726, May 11, 2005, as amended at 77 FR 76248, Dec. 27, 2012; 80 
FR 36222, June 23, 2015]



Sec.  90.1333  Restrictions on the operation of mobile and portable stations.

    (a) Mobile and portable stations may operate only if they can 
positively receive and decode an enabling signal transmitted by a base 
station.
    (b) Any mobile/portable stations may communicate with any other 
mobile/portable stations so long as each mobile/portable can positively 
receive and decode an enabling signal transmitted by a base station.
    (c) Airborne operations by mobile/portable stations is prohibited.



Sec.  90.1335  RF safety.

    Licensees in the 3650-3700 MHz band are subject to the exposure 
requirements found in Sec.  1.1307(b), 2.1091 and 2.1093 of our Rules.



Sec.  90.1337  Operation near Canadian and Mexican borders.

    (a) Fixed devices generally must be located at least 8 kilometers 
from the U.S./Canada or U.S./Mexico border if the antenna of that device 
looks within the 160[deg] sector away from the border. Fixed devices 
must be located at least 56 kilometers from each border if the antenna 
looks within the 200[deg] sector towards the border.
    (b) Fixed devices may be located nearer to the U.S./Canada or U.S./
Mexico border than specified in paragraph (a) of this section only if 
the Commission is able to coordinate such use with Canada or Mexico, as 
appropriate.
    (c) Licensees must comply with the requirements of current and 
future agreements with Canada and Mexico regarding operation in U.S./
Canada and U.S./Mexico border areas.



Sec.  90.1338  Grandfathered operation and transition to Citizens 
Broadband Radio Service.

    (a) Fixed and base station registrations filed in ULS on or before 
April 17, 2015 that are constructed, in service, and fully compliant 
with the rules in part 90, subpart Z as of April 17, 2016 will be 
afforded protection from harmful interference caused by Citizens 
Broadband Radio Service users until the end of their license term (with 
one exception that fixed and base stations registered under licenses 
issued after January 8, 2013 will only be afforded protection until 
April 17, 2020), consistent with Sec.  90.1307. Protection criteria for 
such registered base stations are described in Sec.  96.21of this 
chapter. Registrations originally filed after April 17, 2015 will only 
be afforded protection from harmful interference under this section 
within the licensee's Grandfathered Wireless Protection Zone, as defined 
in Sec. Sec.  96.3 and 96.21 of this chapter.
    (b) Existing licensees as of April 17, 2015 may add new mobile or 
portable stations (as defined in Sec.  90.1333) and/or add new 
subscriber units that operate above the power limit defined in Sec.  
90.1333, only if they can positively receive and decode an enabling 
signal from a base station. Such units will be afforded protection 
within the licensee's Grandfathered Wireless Protection Zone (as defined 
in Sec. Sec.  96.3 and 96.21 of this chapter) until April 17, 2020 or 
until the end of their license term, whichever is later (with one

disaggregates spectrum to another party (partitionee or disaggregatee) 
that would not qualify for an installment payment plan, or elects not to 
pay for its share of the license through installment payments, the 
outstanding principal balance owed by the partitionor or disaggregator 
shall be apportioned according to Sec.  1.2111(e)(3) of this chapter. 
The partitionor or disaggregator is responsible for accrued and unpaid 
interest through and including the consummation date.
    (ii) The partitionee or disaggregatee shall, as a condition of the 
approval of the partial assignment application, pay its entire pro rata 
amount of the outstanding principal balance on or before the 
consummation date. Failure to meet this condition will result in 
cancellation of the grant of the partial assignment application.
    (iii) The partitionor or disaggregator shall be permitted to 
continue to pay its pro rata share of the outstanding balance and, if 
applicable, shall receive loan documents evidencing the partitioning and 
disaggregation. The original interest rate, established pursuant to 
Sec.  1.2110(g)(3)(i) of this chapter at the time of the grant of the 
initial license in the market, shall continue to be applied to the 
partitionor's or disaggregator's portion of the remaining government 
obligation.
    (iv) A default on the partitionor's or disaggregator's payment 
obligation will affect only the partitionor's or disaggregator's portion 
of the market.
    (2) Parties qualified for installment payment plans. (i) Where both 
parties to a partitioning or disaggregation agreement qualify for 
installment payments, the partitionee or disaggregatee will be permitted 
to make installment payments on its portion of the remaining government 
obligation.
    (ii) Each party may be required, as a condition to approval of the 
partial assignment application, to execute loan documents agreeing to 
pay its pro rata portion of the outstanding principal balance due, as 
apportioned according to Sec.  1.2111(e)(3) of this chapter, based upon 
the installment payment terms for which it qualifies under the rules. 
Failure by either party to meet this condition will result in the 
automatic cancellation of the grant of the partial assignment 
application. The interest rate, established pursuant to Sec.  
1.2110(f)(3)(i) of this chapter at the time of the grant of the initial 
license in the market, shall continue to be applied to both parties' 
portion of the balance due. Each party will receive a license for its 
portion of the partitioned market.
    (iii) A default on an obligation will affect only that portion of 
the market area held by the defaulting party.

Sec.  95.1931  Service requirements.

    Subject to the initial construction requirements of Sec.  95.1933 of 
this subpart, each 218-219 MHz Service system license must demonstrate 
that it provides substantial service within the service area. 
Substantial service is defined as a service that is sound, favorable, 
and substantially above a level of service which might minimally warrant 
renewal.



Sec.  95.1933  Construction requirements.

    (a) Each 218-219 MHz Service licensee must make a showing of 
``substantial service'' within ten years of the license grant. Until 
January 1, 2023, ``substantial service'' assessment will be made at 
renewal pursuant to the provisions and procedures contained in Sec.  
1.949 of this chapter.
    (b) Until January 1, 2023, each 218-219 MHz Service licensee must 
file a report to be submitted to inform the Commission of the service 
status of its system. The report must be labeled as an exhibit to the 
renewal application. At minimum, the report must include:
    (1) A description of its current service in terms of geographic 
coverage and population served;

[[Page 558]]

    (2) An explanation of its record of expansion, including a timetable 
of new construction to meet changes in demand for service;
    (3) A description of its investments in its 218-219 MHz Service 
systems;
    (4) A list, including addresses, of all component CTSs constructed; 
and
    (5) Copies of all FCC orders finding the licensee to have violated 
the Communications Act or any FCC rule or policy; and a list of any 
pending proceedings that relate to any matter described in this 
paragraph.
    (c) Failure to demonstrate that substantial service is being 
provided in the service area will result in forfeiture of the license, 
and will result in the licensee's ineligibility to apply for 218-219 MHz 
Service licenses for three years from the date the Commission takes 
final action affirming that the 218-219 MHz Service license has been 
canceled pursuant to Sec.  95.1913 of this part.

Sec.  95.1955  Transmitter effective radiated power limitation.

    The effective radiated power (ERP) of each CTS and RTU shall be 
limited to the minimum necessary for successful communications. No CTS 
or fixed RTU may transmit with an ERP exceeding 20 Watts. No mobile RTU 
may transmit with an ERP exceeding 4 Watts.



Sec.  95.1957  Emission standards.

    (a) All transmissions by each CTS and by each RTU shall use an 
emission type that complies with the following standard for unnecessary 
radiation.
    (b) All spurious and out-of-band emissions shall be attenuated:
    (1) Zero dB on any frequency within the authorized frequency 
segment.
    (2) At least 28 dB on any frequency removed from the midpoint of the 
assigned frequency segment by more than 250 kHz up to and including 750 
kHz;
    (3) At least 35 dB on any frequency removed from the midpoint of the 
assigned frequency segment by more than 750 kHz up to and including 1250 
kHz;
    (4) At least 43 plus 10 log (base 10) (mean power in Watts) dB on 
any frequency removed from the midpoint of the assigned frequency 
segment by more than 1250 kHz.
    (c) When testing for certification, all measurements of unnecessary 
radiation are performed using a carrier frequency as close to the edge 
of the authorized frequency segment as the transmitter is designed to be 
capable of operating.
    (d) The reference bandwidth of the instrumentation used to measure 
the emission power shall be 100 Hz for measuring emissions up to and 
including 250 kHz from the edge of the authorized frequency segment, and 
10 kHz for measuring emissions more than 250 kHz from the edge of the 
authorized frequency segment. If a video filter is used, its bandwidth 
shall not be less than the reference bandwidth. The power level of the 
highest emission within the frequency segment, to which the attenuation 
is referenced, shall be remeasured for each change in reference 
bandwidth.



Sec.  95.1959  Antennas.

    (a) The overall height from ground to topmost tip of the CTS antenna 
shall

[[Page 559]]

not exceed the height necessary to assure adequate service. Certain CTS 
antennas must be individually licensed to the 218-219 MHz System 
licensee (see Sec.  95.1911(b) of this part). CTS antennas must also 
meet the requirements in Sec.  95.317 regarding menaces to air 
navigation. See 47 CFR 95.317 and consult part 17 of the FCC's Rules for 
more information (47 CFR part 17).

6.1 m (20 feet) above ground or above an existing man-made structure 
(other than an antenna structure). Connectors that are used to connect 
RTUs to an external antenna shall not be of the types generally known as 
``F-type'' or ``BNC type.'' Use of an external antenna is subject to 
Sec.  95.1961.



Sec.  95.1961  Interference.

    (a) When a 218-219 MHz Service system suffers harmful interference 
within its service area or causes harmful interference to another 218-
219 MHz Service system, the licensees of both systems must cooperate and 
resolve the problem by mutually satisfactory arrangements. If the 
licensees are unable to do so, the Commission may impose restrictions 
including, but not limited to, specifying the transmitter power, antenna 
height or area, duty cycle, or hours of operation for the stations 
concerned.
    (b) The use of any frequency segment (or portion thereof) at a given 
geographical location may be denied when, in the judgment of the 
Commission, its use in that location is not in the public interest; the 
use of a frequency segment (or portion thereof) specified for the 218-
219 MHz Service system may be restricted as to specified geographical 
areas, maximum power, or other operating conditions.
    (c) A 218-219 MHz Service licensee must provide a copy of the plan 
required by Sec.  95.1915 (a) of this part to every TV Channel 13 
station whose Grade B predicted contour overlaps the licensed service 
area for the 218-219 MHz Service system. The 218-219 MHz Service 
licensee must send the plan to the TV Channel 13 licensee(s) within 10 
days from the date the 218-219 MHz Service licensee submits the plan to 
the Commission, and the 218-219 MHz Service licensee must send updates 
to this plan to the TV Channel 13 licensee(s) within 10 days from the 
date that such updates are filed with the Commission pursuant to Sec.  
95.1915.
    (d) Each 218-219 MHz Service system licensee must provide upon 
request, and install free of charge, an interference reduction device to 
any household within a TV Channel 13 station Grade B predicted contour 
that experiences interference due to a component CTS or RTU.
    (e) Each 218-219 MHz Service system licensee must investigate and 
eliminate harmful interference to television broadcasting and reception, 
from its component CTSs and RTSs, within 30 days of the time it is 
notified in writing, by either an affected television station, an 
affected viewer, or the Commission, of an interference complaint. Should 
the licensee fail to eliminate the interference within the 30-day 
period, the CTS(s) or RTU(s) causing the problem(s) must discontinue 
operation.
    (f) The boundary of the 218-219 MHz Service system, as defined in 
its authorization, is the limit of interference protection for that 218-
219 MHz Service system.

hospitals and other establishments, both Federal and non-Federal, that 
offer services, facilities and beds for use beyond a 24 hour period in 
rendering medical treatment.



Sec.  95.2509  MBAN registration and frequency coordination.

    Operation of Medical Body Area Network (MBAN) devices is subject to 
the frequency coordination procedures in this section.
    (a) The FCC will designate a frequency coordinator(s) to manage the 
operation of medical body area networks by eligible health care 
facilities.
    (b) The frequency coordinator shall perform the following functions:
    (1) Register health care facilities that operate MBAN transmitters, 
maintain a database of these MBAN transmitter locations and operational 
parameters, and provide the FCC with information contained in the 
database upon request;
    (2) Determine if an MBAN is within line-of-sight of an Aeronautical 
Mobile Telemetry (AMT) receive facility in the 2360-2390 MHz band and 
coordinate MBAN operations with the designated AMT frequency 
coordinator, as specified in Sec.  87.305 of this chapter;
    (3) Notify a registered health care facility when an MBAN has to 
change frequency within the 2360-2390 MHz band or to cease operating in 
the band, consistent with a coordination agreement between the MBAN and 
AMT frequency coordinators;
    (4) Develop procedures to ensure that registered health care 
facilities operate an MBAN consistent with the coordination requirements 
under this section; and,
    (5) Identify the MBAN that is the source of interference in response 
to a complaint from the AMT coordinator and notify the health care 
facility of alternative frequencies available for MBAN use or to cease 
operation consistent with the rules.
    (c) Registration. Prior to operating MBAN devices that are capable 
of operation in the 2360-2390 MHz band, a health care facility must 
register with a frequency coordinator designated under Sec.  95.2509. 
Operation of MBAN devices in the 2360-2390 MHz band is prohibited prior 
to the MBAN coordinator notifying the health care facility that 
registration and coordination (to the extent coordination is required 
under paragraph (e) of this section) is complete. The registration must 
include the following information:
    (1) Specific frequencies or frequency range(s) within the 2360-2390 
MHz band to be used, and the capabilities of the MBAN equipment to use 
the 2390-2400 MHz band;
    (2) Equivalent isotropically radiated power;
    (3) Number of MedRadio programmer/control transmitters in use at the 
health care facility as of the date of registration, including 
manufacturer name(s) and model number(s) and FCC identification 
number(s);
    (4) Legal name of the health care facility;
    (5) Location of MedRadio programmer/control transmitters (e.g., 
geographic coordinates, street address, building);
    (6) Point of contact for the health care facility (e.g., name, 
title, office address, phone number, fax number, email address); and,
    (7) In the event that an MBAN has to cease operating in all or a 
portion of the 2360-2390 MHz band due to interference under Sec.  
95.2525 or changes in coordination under paragraph (e) of this section, 
a point of contact (including contractors) for the health care facility 
that is responsible for ensuring that this change is effected whenever 
it is required (e.g., name, title, office address, phone number, fax 
number, email address). The health care facility also must state 
whether, in such cases, its MBAN operation is capable of defaulting to 
the 2390-2400 MHz band and

[[Page 571]]

that it is responsible for ceasing MBAN operations in the 2360-2390 MHz 
band or defaulting traffic to other hospital systems.
    (d) Notification. A health care facility shall notify the MBAN 
frequency coordinator whenever an MBAN programmer/control transmitter in 
the 2360-2390 MHz band is permanently taken out of service, unless it is 
replaced with transmitter(s) using the same technical characteristics as 
those reported on the health care facility's registration, which will 
cover the replacement transmitter(s). A health care facility shall keep 
the information contained in each registration current and shall notify 
the MBAN frequency coordinator of any material change to the MBAN's 
location or operating parameters. In the event that the health care 
facility proposes to change the MBAN's location or operating parameters, 
the MBAN coordinator must first evaluate the proposed changes and comply 
with paragraph (e) of this section as appropriate before the health care 
facility may operate the MBAN in the 2360-2390 MHz band under changed 
operating parameters.
    (e) Coordination procedures. The MBAN coordinator will determine if 
an MBAN is within the line-of-sight of an AMT receive facility in the 
2360-2390 MHz band and notify the health care facility when it may begin 
MBAN operations under the applicable procedures below.
    (1) If the MBAN is beyond the line-of-sight of an AMT receive 
facility, it may operate without prior coordination with the AMT 
coordinator, provided that the MBAN coordinator provides the AMT 
coordinator with the MBAN registration information and the AMT frequency 
coordinator concurs that the MBAN is beyond the line-of-sight prior to 
the MBAN beginning operations in the band.
    (2) If the MBAN is within line-of-sight of an AMT receive facility, 
the MBAN frequency coordinator shall achieve a mutually satisfactory 
coordination agreement with the AMT frequency coordinator prior to the 
MBAN beginning operations in the band. Such coordination agreement shall 
provide protection to AMT receive stations consistent with International 
Telecommunication Union (ITU) Recommendation ITU-R M.1459, ``Protection 
criteria for telemetry systems in the aeronautical mobile service and 
mitigation techniques to facilitate sharing with geostationary 
broadcasting-satellite and mobile-satellite services in the frequency 
bands 1 452-1 525 and 2 310-2 360 MHz,'' May 2000, as adjusted using 
generally accepted engineering practices and standards that are mutually 
agreeable to both coordinators to take into account the local conditions 
and operating characteristics of the applicable AMT and MBAN facilities, 
and shall specify when the device shall limit its transmissions to 
segments of the 2360-2390 MHz band or must cease operation in the band.

``Generally accepted engineering practices and standards'' include, but 
are not limited to, engineering analyses and measurement data as well as 
limiting MBAN operations in the band by time or frequency.
    (3) If an AMT operator plans to operate a receive site not 
previously analyzed by the MBAN coordinator to determine line-of-sight 
to an MBAN facility, the AMT operator shall consider using locations 
that are beyond the line-of-sight of a registered health care facility. 
If the AMT operator determines that non-line-of-sight locations

[[Page 572]]

are not practical for its purposes, the AMT coordinator shall notify the 
MBAN coordinator upon no less than 7 days notice that the registered 
health care facility must cease MBAN operations in the 2360-2390 MHz 
band, unless the parties can achieve a mutually satisfactory 
coordination agreement under paragraph (e)(2) of this section.
    (f) Coordinator functions. The MBAN frequency coordinator shall:
    (1) Provide registration and coordination of MBAN operations to all 
eligible health care facilities on a non-discriminatory basis;
    (2) Provide MBAN registration and coordination services on a not-
for-profit basis;

Sec.  95.2559  MedRadio channel access requirements.

    To reduce interference and make the most effective use of the 
MedRadio frequency bands, MedRadio transmitter types must be designed to 
operate in accordance with the rules in this section.
    (a) Frequency monitoring in the 401-406 MHz band. Except as provided 
in paragraph (b) of this section, all MedRadio programmer/control 
transmitters operating in the 401-406 MHz band must operate under the 
control of a monitoring system that incorporates a mechanism for 
monitoring the channel or channels that the MedRadio system devices 
intend to occupy. The monitoring system antenna shall be the antenna 
normally used by the programmer/control transmitter for a MedRadio 
communications session. Before the monitoring system of a programmer/
control transmitter initiates a MedRadio communications session, the 
following access criteria must be met:
    (1) The monitoring system bandwidth, measured at its 20 dB down 
points, must be equal to or greater than the MedRadio emission bandwidth 
of the intended transmission.
    (2) Within 5 seconds prior to initiating a MedRadio communications 
session, circuitry associated with a MedRadio programmer/control 
transmitter must monitor the channel or channels the system devices 
intend to occupy for a minimum of 10 milliseconds per channel.
    (3) The monitoring threshold power level, PMT, in dBm, is 
calculated using the following formula.

PMT = 10 log B-150 (dBm/Hz) + G


Where:
    (i) B is the MedRadio emission bandwidth in Hertz of the MedRadio 
communications session transmitter having the widest emission; and,
    (ii) G is the MedRadio programmer/control transmitter monitoring 
system antenna gain, in decibels, relative to the gain of an isotropic 
antenna (dBi).
    (4) For the purposes of showing compliance with the above 
provisions, the above calculated threshold power level must be increased 
or decreased by an amount equal to the monitoring system antenna gain 
above or below the gain of an isotropic antenna, respectively.
    (5) If no signal above the monitoring threshold power level is 
detected in a MedRadio channel, the MedRadio programmer/control 
transmitter may initiate on that channel a MedRadio communications 
session involving transmissions to and from a medical implant or medical 
body-worn device. The MedRadio communications session may continue as 
long as any silent period between consecutive data transmission bursts 
does not exceed 5 seconds. If no channel meeting the requirements in 
paragraphs (a)(3) and (4) of this section is available, MedRadio 
transmitters that are capable of operating on multiple channels may 
transmit on the alternate channel accessible by the device with the 
lowest monitored ambient power level.
    (6) When a channel is selected prior to a MedRadio communications 
session, it is permissible to select an alternate channel for use if 
communications are interrupted, provided that the alternate channel 
selected is the next best choice using the criteria specified in 
paragraphs (a)(1) through (5) of this section. The alternate channel may 
be accessed in the event a communications session is interrupted by 
interference. The following criteria must be met:
    (i) Before transmitting on the alternate channel, the channel must 
be monitored for a period of at least 10 milliseconds.
    (ii) The detected power level during this 10 millisecond or greater 
monitoring period must be no higher than 6 dB above the power level 
detected when the channel was chosen as the alternate channel.
    (iii) In the event that this alternate channel provision is not used 
by the

[[Page 575]]

MedRadio system, or if the criteria in paragraphs (i) and (ii) of this 
section are not met, a channel must be selected using the access 
criteria specified in paragraphs (a)(1) through (5) of this section.
    (7) Except as provided in paragraph (b) of this section, MedRadio 
transmitters that operate on a single channel and thus do not have the 
capability of operating on alternate channels may not transmit unless no 
signal on the single channel of operation exceeds the monitoring 
threshold power level.
    (b) Exceptions to frequency monitoring in the 401-406 MHz band. 
MedRadio devices or communications sessions that meet any one of the 
following criteria are not required to be operated in accordance with 
the access rules set forth in paragraph (a) of this section:
    (1) MedRadio communications sessions that are initiated by a medical 
implant event.
    (2) MedRadio devices operating in either the 401-401.85 MHz or 405-
406 MHz bands, provided that the transmit power is not greater than 250 
nanowatts EIRP and the duty cycle for such transmissions does not exceed 
0.1%, based on the total transmission time during a one-hour interval, 
and a maximum of 100 transmissions per hour.
    (3) MedRadio devices operating in the 401.85-402 MHz band, provided 
that the transmit power is not greater than 25 microwatts EIRP and the 
duty cycle for such transmissions does not exceed 0.1%, based on the 
total transmission time during a one-hour interval, and a maximum of 100 
transmissions per hour.
    (4) MedRadio devices operating with a total emission bandwidth not 
exceeding 300 kHz, centered at 403.65 MHz, provided that the transmit 
power is not greater than 100 nanowatts EIRP and the duty cycle for such 
transmissions does not exceed 0.01%, based on the total transmission 
time during a one-hour interval and a maximum of 10 transmissions per 
hour.
    (c) Shared access. The provisions of this section shall not be used 
to extend the range of spectrum occupied over space or time for the 
purpose of denying fair access to spectrum for other MedRadio systems.
    (d) Frequency monitoring in the 413-419 MHz, 426-432 MHz, 438-444 
MHz, and 451-457 MHz bands. MedRadio programmer/control transmitters 
must incorporate a mechanism for monitoring the authorized bandwidth of 
the frequency band that the MedRadio transmitters intend to occupy. The 
monitoring system antenna shall be the same antenna used by the 
programmer/control transmitter for a communications session.
    (1) The MedRadio programmer/control transmitter shall be capable of 
monitoring any occupied frequency band at least once every second and 
monitoring alternate frequency bands within two seconds prior to 
executing a change to an alternate frequency band.
    (2) The MedRadio programmer/control transmitter shall move to 
another authorized frequency band within one second of detecting a 
persistent (i.e., lasting more than 50 milliseconds) signal level 
greater than -60 dBm as received by a 0 dBi gain antenna in any 12.5 kHz 
bandwidth within the authorized bandwidth.
    (3) The MedRadio programmer/control transmitter shall be capable of 
monitoring the authorized bandwidth of the occupied frequency band to 
determine whether either direction of the communications link is 
becoming degraded to the extent that communications is likely to be lost 
for more than 45 milliseconds. Upon making such a determination the 
MedRadio programmer/control transmitter shall move to another authorized 
frequency band.
    (e) System shutdown. MedRadio transmitters shall incorporate a 
programmable means to implement a system shutdown process in the event 
of communication failure, on command from the MedRadio programmer/
control transmitter, or when no authorized alternate frequency band is 
available. The shutdown process shall commence within 45 milliseconds 
after loss of the communication link or receipt of the shutdown command 
from the MedRadio programmer/control transmitter. This requirement does 
not apply to MedRadio operations in the 401-406 MHz band.
    (f) Requirements for MBANs. A MedRadio programmer/control 
transmitter and its associated medical body-

[[Page 576]]

worn transmitters shall not commence operating in, and shall 
automatically cease operating in, the 2360-2390 MHz band if the 
programmer/control transmitter does not receive, in accordance with the 
protocols specified by the manufacturer, a control message permitting 
such operation. Medical body-worn transmitters shall cease operating in 
2360-2390 MHz if they lose communication with their associated 
programmer/control transmitter. Additionally, a MedRadio programmer/
control transmitter and its associated medical body-worn transmitters 
operating in the 2360-2390 MHz band shall comply with a control message 
that notifies the devices to limit transmissions to segments of the 
2360-2390 MHz band or to cease operation in the band.

than 150 kHz away from the center frequency of the MedRadio channel the 
transmission is intended to occupy;
    (2) 20 dB, on any frequency between 401.750 MHz and 402.000 MHz, and 
on any frequency between 405 MHz and 405.250 MHz.

sensors and radar systems operating in the 76-81 GHz band: 1000 pW/cm\2\ 
at a distance of 3 meters from the exterior surface of the radiating 
structure.
    (3) For field disturbance sensors and radar systems operating in the 
76-81 GHz band, the spectrum shall be investigated up to 231.0 GHz.
    (b) Fundamental emissions must be contained within the frequency 
bands specified in this section during all conditions of operation. 
Equipment is presumed to operate over the temperature range -20 to +50 
degrees Celsius with an input voltage variation of 85% to 115% of rated 
input voltage, unless justification is presented to demonstrate 
otherwise.

FR 25315, May 1, 2020]



Sec.  96.25  Priority access licenses.

    (a) Priority Access Licensees must operate CBSDs consistent with the 
technical rules and interference protection requirements set forth in 
this part.
    (b) PALs have the following parameters:
    (1) Geography: Each PAL consists of a single License Area.
    (i) Contiguous geographic areas: An SAS must assign geographically 
contiguous PALs held by the same Priority Access Licensee to the same 
channels in each geographic area, to the extent feasible. The SAS may 
temporarily reassign individual PALs held by the same Priority Access 
Licensee to different channels, so that geographical contiguity is 
temporarily not maintained, to the extent necessary to protect Incumbent 
Users or if necessary to perform its required functions under subpart F 
of this part.
    (ii) [Reserved]
    (2) Channels: Each PAL consists of a 10 megahertz channel within the 
frequency range set forth in Sec.  96.11. Channels must be assigned by 
the SAS. Priority Access Licensees may request a particular channel or 
frequency range from the SAS but will not be guaranteed a particular 
assignment.
    (i) Contiguous channels: An SAS must assign multiple channels held 
by the same Priority Access Licensee to contiguous channels in the same 
License Area, to the extent feasible. The SAS may temporarily reassign 
individual PALs to non-contiguous channels to the extent necessary to 
protect Incumbent Users or if necessary to perform its required 
functions under subpart F of this part.
    (ii) [Reserved]
    (3) License term. Each PAL has a ten-year license term. Licensees 
must file a renewal application in accordance with the provisions of 
Sec.  1.949 of this chapter.
    (4) Performance requirement. Priority Access Licensees must provide 
substantial service in their license area by the end of the initial 
license term. ``Substantial'' service is defined as service which is 
sound, favorable, and substantially above the level of mediocre service 
which might minimally warrant renewal. Failure by any licensee to meet 
this requirement will result in forfeiture of the license without 
further Commission action, and the licensee will be ineligible to regain 
it. Licensees shall demonstrate compliance with the performance 
requirement by filing a construction notification with the Commission in 
accordance with the provisions set forth in Sec.  1.946(d) of this 
chapter. The licensee must certify whether it has met the performance 
requirement, and file supporting documentation, including description 
and demonstration of the bona fide service provided, electronic maps 
accurately depicting the boundaries of the license area and where in the 
license area the licensee provides service that meets the performance 
requirement, supporting technical documentation, any population-related 
assumptions or data used in determining the population covered by a 
service to the extent any were relied upon, and any other information 
the Wireless Telecommunications Bureau may prescribe by public notice. A 
licensee's showing of substantial service may not rely on service 
coverage outside of the PAL Protection Areas of registered CBSDs or on 
deployments that are not reflected in SAS records of CBSD registrations.
    (i) Safe harbor for mobile or point-to-multipoint service. A 
Priority Access Licensee providing a mobile service or point-to-
multipoint service may demonstrate substantial service by showing that 
it provides signal coverage and offers service, either to customers or 
for internal use, over at least 50 percent of the population in the 
license area.
    (ii) Safe harbor for fixed point-to-point service. A Priority Access 
Licensee providing a fixed point-to-point service may demonstrate 
substantial service by showing that it has constructed and operates at 
least four links, either to customers or for internal use, in license 
areas with 134,000 population or less and in license areas with greater 
population, a minimum number of

[[Page 601]]

links equal to the population of the license area divided by 33,500 and 
rounded up to the nearest whole number. To satisfy this provision, such

shall not be considered in use and will be excluded from the calculation 
of the PAL Protection Area until such time as contact with the SAS is 
re-established.
    (2) The default protection contour will be determined by the SAS as 
a -96 dBm/10 MHz contour around each CBSD. The default protection 
contour will be calculated based on information included in the CBSD 
registration and shall be determined and enforced consistently across 
all SASs.
    (i) The default protection contour is the outer limit of the PAL 
Protection Area for any CBSD but a Priority Access Licensee may choose 
to self-report protection contours smaller than the default protection 
contour to the SAS.
    (ii) If the PAL Protection Areas for multiple CBSDs operated by the 
same Priority Access Licensees overlap, the SAS shall combine the PAL 
Protection Areas for such CBSDs into a single protection area.
    (3) The PAL Protection Area may not extend beyond the boundaries of 
the Priority Access Licensee's Service Area.

    (a) Geo-location and reporting capability. (1) All CBSDs must be 
able to determine their geographic coordinates (referenced to the North 
American Datum of 1983 (NAD83)) to an accuracy of 50 meters horizontal and 3 meters 
of elevation. Such geographic coordinates shall be reported to an SAS at 
the time of first activation from a power-off condition.

[[Page 603]]

    (2) For professionally installed CBSDs, geographic coordinates to 
the same accuracy specified in paragraph (a)(1) of this section may be 
determined and reported to the SAS as part of the installation and 
registration process. Geographic coordinates must be determined and 
reported each time the CBSD is moved to a new location.
    (3) A non-professionally installed CBSD must check its location and 
report to the SAS any location changes exceeding 50 meters horizontal 
and 3 meters elevation from its last reported 
location within 60 seconds of such location change.
    (b) Operability. All CBSDs must be capable of two-way operation on 
any authorized frequency assigned by an SAS. Equipment deployed by 
Grandfathered Wireless Broadband Licensees during their license term 
will be exempt from this requirement.
    (c) Registration with SAS. A CBSD must register with and be 
authorized by an SAS prior to its initial service transmission. The CBSD 
must provide the SAS upon its registration with its geographic location, 
antenna height above ground level (in meters), CBSD class (Category A/
Category B), requested authorization status (Priority Access or General 
Authorized Access), FCC identification number, call sign, user contact 
information, air interface technology, unique manufacturer's serial 
number, sensing capabilities (if supported), and additional information 
on its deployment profile required by Sec. Sec.  96.43 and 96.45. If any 
of this information changes, the CBSD shall update the SAS within 60 
seconds of such change, except as otherwise set forth in this section. 
All information provided by the CBSD to the SAS must be true, complete, 
correct, and made in good faith.

authorized by an SAS, consistent with its FCC equipment authorization, 
and within geographic areas permitted by an SAS on the channels or 
frequencies authorized by an SAS.
    (2) A CBSD must receive and comply with any incoming commands from 
its associated SAS about any changes to power limits and frequency 
assignments. A CBSD must cease transmission, move to another frequency 
range, or change its power level within 60 seconds as instructed by an 
SAS.
    (d) Signal Level Reporting. A CBSD must report to an SAS regarding 
received signal strength in its occupied frequencies and adjacent 
frequencies, received packet error rates or other common standard 
metrics of interference for itself and associated End User Devices as 
directed by an SAS.
    (e) Frequency reporting. If directed by the SAS, a CBSD that 
receives a range of available frequencies or channels from an SAS must 
promptly report to the SAS which of the available channels or 
frequencies it will utilize.
    (f) Security. CBSDs shall incorporate security measures sufficient 
to ensure that they are capable of communicating only with SASs operated 
by approved SAS Administrators, and that communications between CBSDs 
and SASs, between individual CBSDs, and between CBSDs and End User 
Devices are secure to prevent corruption or unauthorized interception of 
data.
    (1) For purposes of obtaining operational limits and frequency 
availabilities and their updates, CBSDs shall only contact SASs operated 
by SAS Administrators approved by the Commission in accordance with 
subpart F of this part.
    (2) All communications between CBSDs and SASs must be transmitted 
using secure methods that protect the systems from corruption or 
unauthorized modification of the data.
    (3) Communications between a CBSD and its associated End User 
Devices for purposes of obtaining operational power, location, and 
frequency assignments shall employ secure methods that protect the 
system from corruption or unauthorized modification of the data.
    (g) Device security. All CBSDs and End User Devices must contain 
security features sufficient to protect against modification of software 
and firmware by unauthorized parties. Applications for certification of 
CBSDs and End User Devices must include an operational description of 
the technologies and measures that are incorporated in the device to 
comply with

[[Page 604]]

the security requirements of this section. In addition, applications for 
certification of CBSDs and End User Devices must identify at least one 
of the SAS databases operated by an approved SAS Administrator that the 
device will access for channel/frequency availability and affirm that 
the device will conform to the communications security methods used by 
such databases.
    (h) Airborne operations. Airborne operations by CBSDs and End User 
Devices are prohibited.



Sec.  96.41  General radio requirements.

    The requirements in this section apply to CBSDs and their associated 
End User Devices, unless otherwise specified.

[GRAPHIC] [TIFF OMITTED] TR07DE18.009

    (i) Except as otherwise specified in paragraph (e)(2) of this 
section, for channel and frequency assignments made by the SAS to CBSDs, 
the conducted power of any CBSD emission outside the fundamental 
emission bandwidth as specified in paragraph (e)(3) of this section 
(whether the emission is inside or outside of the authorized band) shall 
not exceed -13 dBm/MHz within 0-10 megahertz above the upper SAS-
assigned channel edge and within 0-10 megahertz below the lower SAS-
assigned channel edge. At all frequencies greater than 10 megahertz 
above the upper SAS assigned channel edge and less than 10 MHz below the 
lower SAS assigned channel edge, the conducted power of any CBSD 
emission shall not exceed -25 dBm/MHz. The upper and lower SAS assigned 
channel edges are the upper and lower limits of any channel assigned to 
a CBSD by an SAS, or in the case of multiple contiguous channels, the 
upper and lower limits of the combined contiguous channels.
    (ii) Except as otherwise specified in paragraph (e)(2) of this 
section, for channel and frequency assignments made by a CBSD to End 
User Devices, the conducted power of any End User Device emission 
outside the fundamental emission (whether in or outside of the 
authorized band) shall not exceed -13 dBm/MHz within 0 to B megahertz 
(where B is the bandwidth in megahertz of the assigned channel or 
multiple contiguous channels of the End User Device) above the upper 
CBSD-assigned channel edge and within 0 to B megahertz below the lower 
CBSD-assigned channel edge. At all frequencies greater than B megahertz 
above the upper CBSD assigned channel edge and less than B megahertz 
below the lower CBSD-assigned channel edge, the conducted power of any 
End User Device emission shall not exceed -25 dBm/MHz. Notwithstanding 
the emission limits in this paragraph, the Adjacent Channel Leakage 
Ratio for End User Devices shall be at least 30 dB.
    (2) Additional protection levels. Notwithstanding paragraph (e)(1) 
of this section, for CBSDs and End User Devices, the conducted power of 
emissions below 3540 MHz or above 3710 MHz shall not exceed -25 dBm/MHz, 
and the conducted power of emissions below 3530 MHz or above 3720 MHz 
shall not exceed -40dBm/MHz.
    (3) Measurement procedure. (i) Compliance with this provision is 
based on the use of measurement instrumentation employing a resolution 
bandwidth of 1 megahertz or greater. However, in the 1

[[Page 606]]

megahertz bands immediately outside and adjacent to the licensee's 
authorized frequency channel, a resolution bandwidth of no less than one 
percent of the fundamental emission bandwidth may be employed. A 
narrower resolution bandwidth is permitted in all cases to improve 
measurement accuracy provided the measured power is integrated over the 
full reference bandwidth (i.e., 1 MHz or 1 percent of emission 
bandwidth, as specified). The fundamental emission bandwidth is defined 
as the width of the signal between two points, one below the carrier 
center frequency and one above the carrier center frequency, outside of 
which all emissions are attenuated at least 26 dB below the transmitter 
power.
    (ii) When measuring unwanted emissions to demonstrate compliance 
with the limits, the CBSD and End User Device nominal carrier frequency/
channel shall be adjusted as close to the licensee's authorized 
frequency block edges, both upper and lower, as the design permits.
    (iii) Compliance with emission limits shall be demonstrated using 
either average (RMS)-detected or peak-detected power measurement 
techniques.
    (4) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in this section.
    (f) Reception limits. Priority Access Licensees must accept adjacent 
channel and in-band blocking interference (emissions from other 
authorized Priority Access or GAA CBSDs transmitting between 3550 and 
3700 MHz) up to a power spectral density level not to exceed -40 dBm in 
any direction with greater than 99% probability when integrated over a 
10 megahertz reference bandwidth, with the measurement antenna placed at 
a height of 1.5 meters above ground level, unless the affected Priority 
Access Licensees agree to an alternative limit and communicates that to 
the SAS.

    Note to paragraph (f): Citizens Broadband Radio Service users should 
be aware that there are Federal Government radar systems in the band and 
adjacent bands that could adversely affect their operations.

    (g) Power measurement. The peak-to-average power ratio (PAPR) of any 
CBSD transmitter output power must not exceed 13 dB. PAPR measurements 
should be made using either an instrument with complementary cumulative 
distribution function (CCDF) capabilities or another Commission approved 
procedure. The measurement must be performed using a signal 
corresponding to the highest PAPR expected during periods of continuous 
transmission.

    (c) The station must not constitute a hazard to the safety of life 
or property. For a station aboard an aircraft, the apparatus shall not 
be operated while the aircraft is operating under Instrument Flight 
Rules, as defined by the FAA, unless the station has been found to 
comply with all applicable FAA Rules.



Sec.  97.13  Restrictions on station location.

    (a) Before placing an amateur station on land of environmental 
importance or that is significant in American history, architecture or 
culture, the licensee may be required to take certain actions prescribed 
by Sec. Sec.  1.1305-1.1319 of this chapter.
    (b) A station within 1600 m (1 mile) of an FCC monitoring facility 
must protect that facility from harmful interference. Failure to do so 
could result in imposition of operating restrictions upon the amateur 
station pursuant to Sec.  97.121. Geographical coordinates of the 
facilities that require protection are listed in Sec.  0.121(c) of this 
chapter.
    (c) Before causing or allowing an amateur station to transmit from 
any place where the operation of the station could cause human exposure 
to RF electromagnetic field levels in excess of those allowed under 
Sec.  1.1310 of this chapter, the licensee is required to take certain 
actions.
    (1) The licensee shall ensure compliance with the Commission's radio 
frequency exposure requirements in Sec. Sec.  1.1307(b), 2.1091, and 
2.1093 of this chapter, where applicable. In lieu of evaluation with the 
general population/uncontrolled exposure limits, amateur licensees may 
evaluate their operation with respect to members of his or her immediate 
household using the occupational/controlled exposure limits in Sec.  
1.1310, provided appropriate training and information has been accessed 
by the amateur licensee and members of his/her household. RF exposure of 
other nearby persons who are not members of the amateur licensee's 
household must be evaluated with respect to the general population/
uncontrolled exposure limits. Appropriate methodologies and guidance for 
evaluating amateur radio service operation is described in the Office of 
Engineering and Technology (OET) Bulletin 65, Supplement B.
    (2) If the routine environmental evaluation indicates that the RF 
electromagnetic fields could exceed the limits contained in Sec.  1.1310 
of this chapter in accessible areas, the licensee must take action to 
prevent human exposure to such RF electromagnetic fields. Further 
information on evaluating compliance with these limits can be found in 
the FCC's OET Bulletin Number 65, ``Evaluating Compliance with FCC

[[Page 618]]

Guidelines for Human Exposure to Radiofrequency Electromagnetic 
Fields.''

airport must notify the Federal Aviation Administration and register 
with the Commission as required by part 17 of this chapter.
    (b) Except as otherwise provided herein, a station antenna structure 
may be erected at heights and dimensions sufficient to accommodate 
amateur service communications. (State and local regulation of a station 
antenna structure must not preclude amateur service communications. 
Rather, it must reasonably accommodate such communications and must 
constitute the minimum practicable regulation to accomplish the state or 
local authority's legitimate purpose. See PRB-1, 101 FCC 2d 952 (1985) 
for details.)
    (c) Antennas used to transmit in the 2200 m and 630 m bands must not 
exceed 60 meters in height above ground level.

Sec.  97.17  Application for new license grant.

    (a) Any qualified person is eligible to apply for a new operator/
primary station, club station or military recreation station license 
grant. No new license grant will be issued for a Novice or Advanced 
Class operator/primary station.
    (b) Each application for a new amateur service license grant must be 
filed with the FCC as follows:
    (1) Each candidate for an amateur radio operator license which 
requires the applicant to pass one or more examination elements must 
present the administering VEs with all information required by the rules 
prior to the examination. The VEs may collect all necessary information 
in any manner of their choosing, including creating their own forms.
    (2) For a new club or military recreation station license grant, 
each applicant must present all information required by the rules to an 
amateur radio organization having tax-exempt status under section 
501(c)(3) of the Internal Revenue Code of 1986 that provides voluntary, 
uncompensated and unreimbursed services in providing club and military 
recreation station call signs (``Club Station Call Sign Administrator'') 
who must submit the information to the FCC in an electronic batch file. 
The Club Station Call Sign Administrator may collect the information 
required by these rules in any manner of their choosing, including 
creating their own forms. The Club Station Call Sign Administrator must 
retain the applicants information for at least 15 months and make it 
available to the FCC upon request. The FCC will issue public 
announcements listing the qualified organizations that have completed a 
pilot autogrant batch filing project and are authorized to serve as a 
Club Station Call Sign Administrator.
    (c) No person shall obtain or attempt to obtain, or assist another 
person to obtain or attempt to obtain, an amateur service license grant 
by fraudulent means.
    (d) One unique call sign will be shown on the license grant of each 
new primary, club and military recreation station. The call sign will be 
selected by the sequential call sign system. Effective February 14, 
2011, no club station license grants will be issued to a licensee who is 
shown as the license trustee on an existing club station license grant.

Sec.  97.19  Application for a vanity call sign.

    (a) The person named in an operator/primary station license grant or 
in a club station license grant is eligible to make application for 
modification of the license grant, or the renewal thereof, to show a 
call sign selected by the vanity call sign system. Effective February 
14, 2011, the person named in a

[[Page 619]]

club station license grant that shows on the license a call sign that 
was selected by a trustee is not eligible for an additional vanity call 
sign. (The person named in a club station license grant that shows on 
the license a call sign that was selected by a trustee is eligible for a 
vanity call sign for his or her operator/primary station license grant 
on the same basis as any other person who holds an operator/primary 
station license grant.) Military recreation stations are not eligible 
for a vanity call sign.
    (b) Each application for a modification of an operator/primary or 
club station license grant, or the renewal thereof, to show a call sign 
selected by the vanity call sign system must be filed in accordance with 
Sec.  1.913 of this chapter.
    (c) Unassigned call signs are available to the vanity call sign 
system with the following exceptions:
    (1) A call sign shown on an expired license grant is not available 
to the vanity call sign system for 2 years following the expiration of 
the license.
    (2) A call sign shown on a surrendered or canceled license grant 
(except for a license grant that is canceled pursuant to Sec.  97.31) is 
not available to the vanity call sign system for 2 years following the 
date such action is taken. (The availability of a call sign shown on a 
license canceled pursuant to Sec.  97.31 is governed by paragraph (c)(3) 
of this section.)
    (i) This 2-year period does not apply to any license grant pursuant 
to paragraph (c)(3)(i), (ii), or (iii) of this section that is 
surrendered, canceled, revoked, voided, or set aside because the grantee 
acknowledged or the Commission determined that the grantee was not 
eligible for the exception. In such a case, the call sign is not 
available to the vanity call sign system for 30 days following the date 
such action is taken, or for the period for which the call sign would 
not have been available to the vanity call sign system pursuant to 
paragraphs (c)(2) or (3) of this section but for the intervening grant 
to the ineligible applicant, whichever is later.
    (ii) An applicant to whose operator/primary station license grant, 
or club station license grant for which the applicant is the trustee, 
the call sign was previously assigned is exempt from the 2-year period 
set forth in paragraph (c)(2) of this section.
    (3) A call sign shown on a license canceled pursuant to Sec.  97.31 
of this part is not available to the vanity call sign system for 2 years 
following the person's death, or for 2 years following the expiration of 
the license grant, whichever is sooner. If, however, a license is 
canceled more than 2 years after the licensee's death (or within 30 days 
before the second anniversary of the licensee's death), the call sign is 
not available to the vanity call sign system for 30 days following the 
date such action is taken. The following applicants are exempt from this 
2-year period:
    (i) An applicant to whose operator/primary station license grant, or 
club station license grant for which the applicant is the trustee, the 
call sign was previously assigned; or
    (ii) An applicant who is the spouse, child, grandchild, stepchild, 
parent, grandparent, stepparent, brother, sister, stepbrother, 
stepsister, aunt, uncle, niece, nephew, or in-law of the person now 
deceased or of any other deceased former holder of the call sign, 
provided that the vanity call sign requested by the applicant is from 
the group of call signs corresponding to the same or lower class of 
operator license held by the applicant as designated in the sequential 
call sign system; or
    (iii) An applicant who is a club station license trustee acting with 
a written statement of consent signed by either the licensee ante mortem 
but who is now deceased, or by at least one relative as listed in 
paragraph (c)(3)(ii) of this section, of the person now deceased or of 
any other deceased former holder of the call sign, provided that the 
deceased former holder was a member of the club during his or her life.
    (d) The vanity call sign requested by an applicant must be selected 
from the group of call signs corresponding to the same or lower class of 
operator license held by the applicant as designated in the sequential 
call sign system.
    (1) The applicant must request that the call sign shown on the 
license grant be vacated and provide a list of

[[Page 620]]

up to 25 call signs in order of preference. In the event that the 
Commission receives more than one application requesting a vanity call 
sign from an applicant on the same receipt day, the Commission will 
process only the first such application entered into the Universal 
Licensing System. Subsequent vanity call sign applications from that 
applicant with the same receipt date will not be accepted.
    (2) The first assignable call sign from the applicant's list will be 
shown on the license grant. When none of those call signs are 
assignable, the call sign vacated by the applicant will be shown on the 
license grant.
    (3) Vanity call signs will be selected from those call signs 
assignable at the time the application is processed by the FCC.
    (4) A call sign designated under the sequential call sign system for 
Alaska, Hawaii, Caribbean Insular Areas, and Pacific Insular areas will 
be assigned only to a primary or club station whose licensee's mailing 
address is in the corresponding state, commonwealth, or island. This 
limitation does not apply to an applicant for the call sign as the 
spouse, child, grandchild, stepchild, parent, grandparent, stepparent, 
brother, sister, stepbrother, stepsister, aunt, uncle, niece, nephew, or 
in-law, of the former holder now deceased.

    (iii) For a club station or military recreation station license 
grant showing a call sign obtained through the sequential call sign 
system, and for a club station license grant showing a call sign 
obtained through the vanity call sign system but whose grantee does not 
want to have the vanity call sign reassigned to the station, the 
application must be presented in document form to a Club Station Call 
Sign Administrator who must submit the information thereon to the FCC in 
an electronic batch file. The replacement call sign will be selected by 
the sequential call sign system. The Club Station Call Sign 
Administrator must retain the collected information for at least 15 
months and make it available to the FCC upon request.
    (b) A person whose amateur station license grant has expired may 
apply to the FCC for renewal of the license grant for another term 
during a 2 year filing grace period. The application must be received at 
the address specified above prior to the end of the grace period. Unless 
and until the license grant is renewed, no privileges in this part are 
conferred.
    (c) Except as provided in paragraph (a)(3) of this section, a call 
sign obtained under the sequential or vanity call sign system will be 
reassigned to the station upon renewal or modification of a station 
license.

provisions of the Communications Act of 1934, as amended, or of any 
treaty ratified by the United States.
    (b) When the FCC makes such a determination, it will issue an order 
of modification. The order will not become final until the licensee is 
notified in writing of the proposed action and the grounds and reasons 
therefor. The licensee will be given reasonable opportunity of no less 
than 30 days to protest the modification; except that, where safety of 
life or property is involved, a shorter period of notice may be 
provided. Any protest by a licensee of an FCC order of modification will 
be handled in accordance with the provisions of 47 U.S.C. 316.

                  Subpart B_Station Operation Standards



Sec.  97.101  General standards.

    (a) In all respects not specifically covered by FCC Rules each 
amateur station must be operated in accordance with good engineering and 
good amateur practice.
    (b) Each station licensee and each control operator must cooperate 
in selecting transmitting channels and in making the most effective use 
of the amateur service frequencies. No frequency will be assigned for 
the exclusive use of any station.

give priority to stations providing emergency communications, except to 
stations transmitting communications for training drills and tests in 
RACES.
    (d) No amateur operator shall willfully or maliciously interfere 
with or cause interference to any radio communication or signal.



Sec.  97.103  Station licensee responsibilities.

    (a) The station licensee is responsible for the proper operation of 
the station in accordance with the FCC Rules. When the control operator 
is a different amateur operator than the station licensee, both persons 
are equally responsible for proper operation of the station.
    (b) The station licensee must designate the station control 
operator. The FCC will presume that the station licensee is also the 
control operator, unless documentation to the contrary is in the station 
records.
    (c) The station licensee must make the station and the station 
records available for inspection upon request by an FCC representative.

[54 FR 25857, June 20, 1989, as amended at 71 FR 66462, Nov. 15, 2006;

Sec.  97.105  Control operator duties.

    (a) The control operator must ensure the immediate proper operation 
of the station, regardless of the type of control.
    (b) A station may only be operated in the manner and to the extent 
permitted by the privileges authorized for the class of operator license 
held by the control operator.



Sec.  97.107  Reciprocal operating authority.

    A non-citizen of the United States (``alien'') holding an amateur 
service authorization granted by the alien's government is authorized to 
be the control operator of an amateur station located at places where 
the amateur service is regulated by the FCC, provided there is in effect 
a multilateral or bilateral reciprocal operating arrangement, to which 
the United States and the alien's government are parties, for amateur 
service operation on a reciprocal basis. The FCC will issue public 
announcements listing the countries with which the United States has 
such an arrangement. No citizen of the United States or person holding 
an FCC amateur operator/primary station license grant is eligible for 
the reciprocal operating authority granted by this section. The 
privileges granted to a control operator under this authorization are:
    (a) For an amateur service license granted by the Government of 
Canada:
    (1) The terms of the Convention Between the United States and Canada 
(TIAS No. 2508) Relating to the Operation by Citizens of Either Country 
of Certain Radio Equipment or Stations in the Other Country;
    (2) The operating terms and conditions of the amateur service 
license issued by the Government of Canada; and
    (3) The applicable rules of this part, but not to exceed the control 
operator

[[Page 623]]

privileges of an FCC-granted Amateur Extra Class operator license.
    (b) For an amateur service license granted by any country, other 
than Canada, with which the United States has a multilateral or 
bilateral agreement:

service and to remarks of a personal character.

[71 FR 25982, May 3, 2006]



Sec.  97.119  Station identification.

    (a) Each amateur station, except a space station or telecommand 
station, must transmit its assigned call sign on its transmitting 
channel at the end of each communication, and at least every 10 minutes 
during a communication, for the purpose of clearly making the source of 
the transmissions from the station known to those receiving the 
transmissions. No station may transmit unidentified communications or 
signals, or transmit as the station call sign, any call sign not 
authorized to the station.
    (b) The call sign must be transmitted with an emission authorized 
for the transmitting channel in one of the following ways:
    (1) By a CW emission. When keyed by an automatic device used only 
for identification, the speed must not exceed 20 words per minute;
    (2) By a phone emission in the English language. Use of a phonetic 
alphabet as an aid for correct station identification is encouraged;
    (3) By a RTTY emission using a specified digital code when all or 
part of the communications are transmitted by a RTTY or data emission;
    (4) By an image emission conforming to the applicable transmission 
standards, either color or monochrome, of Sec.  73.682(a) of the FCC 
Rules when all or part of the communications are transmitted in the same 
image emission
    (c) One or more indicators may be included with the call sign. Each 
indicator must be separated from the call sign by the slant mark (/) or 
by any suitable word that denotes the slant mark. If an indicator is 
self-assigned, it must be included before, after, or both before and 
after, the call sign. No self-assigned indicator may conflict with any 
other indicator specified by the FCC Rules or with any prefix assigned 
to another country.
    (d) When transmitting in conjunction with an event of special 
significance, a station may substitute for its assigned call sign a 
special event call sign as shown for that station for that period

[[Page 626]]

of time on the common data base coordinated, maintained and disseminated 
by the special event call sign data base coordinators. Additionally, the 
station must transmit its assigned call sign at least once per hour 
during such transmissions.
    (e) When the operator license class held by the control operator 
exceeds that of the station licensee, an indicator consisting of the 
call sign assigned to the control operator's station must be included 
after the call sign.
    (f) When the control operator is a person who is exercising the 
rights and privileges authorized by Sec.  97.9(b) of this part, an 
indicator must be included after the call sign as follows:
    (1) For a control operator who has requested a license modification 
from Novice Class to Technical Class: KT;
    (2) For a control operator who has requested a license modification 
from Novice or Technician to General Class: AG;
    (3) For a control operator who has requested a license modification 
from Novice, Technician, General, or Advanced Class to Amateur Extra 
Class: AE.
    (g) When the station is transmitting under the authority of Sec.  
97.107 of this part, an indicator consisting of the appropriate letter-
numeral designating the station location must be included before the 
call sign that was issued to the station by the country granting the 
license. For an amateur service license granted by the Government of 
Canada, however, the indicator must be included after the call sign. At 
least once during each intercommunication, the identification 
announcement must include the geographical location as nearly as 
possible by city and state, commonwealth or possession.

    (g) The license grantee of each space station must make the 
following written notifications to the Space Bureau, FCC, Washington, DC 
20554.
    (1) A pre-space notification within 30 days after the date of launch 
vehicle determination, but no later than 90 days before integration of 
the space station into the launch vehicle. The notification must be in 
accordance with the provisions of Articles 9 and 11 of the International 
Telecommunication Union (ITU) Radio Regulations and must specify the 
information required by Appendix 4 and Resolution No. 642 of the ITU 
Radio Regulations. The notification must also include a description of 
the design and operational strategies that the space station will use to 
mitigate orbital debris, including the following information:
    (i) A statement that the space station operator has assessed and 
limited the amount of debris released in a planned manner during normal 
operations. Where applicable, this statement must include an orbital 
debris mitigation disclosure for any separate deployment devices, 
distinct from the space station launch vehicle, that may become a source 
of orbital debris;
    (ii) A statement indicating whether the space station operator has 
assessed and limited the probability that the space station(s) will 
become a source of debris by collision with small debris or meteoroids 
that would cause loss of control and prevent disposal. The statement 
must indicate whether this

[[Page 629]]

probability for an individual space station is 0.01 (1 in 100) or less, 
as calculated using the NASA Debris Assessment Software or a higher 
fidelity assessment tool;
    (iii) A statement that the space station operator has assessed and 
limited the probability, during and after completion of mission 
operations, of accidental explosions or of release of liquids that will 
persist in droplet form. This statement must include a demonstration 
that debris generation will not result from the conversion of energy 
sources on board the spacecraft into energy that fragments the 
spacecraft. Energy sources include chemical, pressure, and kinetic 
energy. This demonstration should address whether stored energy will be 
removed at the spacecraft's end of life, by depleting residual fuel and 
leaving all fuel line valves open, venting any pressurized system, 
leaving all batteries in a permanent discharge state, and removing any 
remaining source of stored energy, or through other equivalent 
procedures specifically disclosed in the application;
    (iv) A statement that the space station operator has assessed and 
limited the probability of the space station(s) becoming a source of 
debris by collisions with large debris or other operational space 
stations.
    (A) Where the application is for an NGSO space station or system, 
the following information must also be included:
    (1) A demonstration that the space station operator has assessed and 
limited the probability of collision between any space station of the 
system and other large objects (10 cm or larger in diameter) during the 
total orbital lifetime of the space station, including any de-orbit 
phases, to less than 0.001 (1 in 1,000). The probability shall be 
calculated using the NASA Debris Assessment Software or a higher 
fidelity assessment tool. The collision risk may be assumed zero for a 
space station during any period in which the space station will be 
maneuvered effectively to avoid colliding with large objects.
    (2) The statement must identify characteristics of the space 
station(s)' orbits that may present a collision risk, including any 
planned and/or operational space stations in those orbits, and indicate 
what steps, if any, have been taken to coordinate with the other 
spacecraft or system, or what other measures the operator plans to use 
to avoid collision.
    (3) If at any time during the space station(s)' mission or de-orbit 
phase the space station(s) will transit through the orbits used by any 
inhabitable spacecraft, including the International Space Station, the 
statement must describe the design and operational strategies, if any, 
that will be used to minimize the risk of collision and avoid posing any 
operational constraints to the inhabitable spacecraft.
    (4) The statement must disclose the accuracy, if any, with which 
orbital parameters will be maintained, including apogee, perigee, 
inclination, and the right ascension of the ascending node(s). In the 
event that a system is not be maintained to specific orbital tolerances, 
e.g., its propulsion system will not be used for orbital maintenance, 
that fact should be included in the debris mitigation disclosure. Such 
systems must also indicate the anticipated evolution over time of the 
orbit of the proposed satellite or satellites. All systems must describe 
the extent of satellite maneuverability, whether or not the space 
station design includes a propulsion system.
    (5) The space station operator must certify that upon receipt of a 
space situational awareness conjunction warning, the operator will 
review and take all possible steps to assess the collision risk, and 
will mitigate the collision risk if necessary. As appropriate, steps to 
assess and mitigate the collision risk should include, but are not 
limited to: Contacting the operator of any active spacecraft involved in 
such a warning; sharing ephemeris data and other appropriate operational 
information with any such operator; and modifying space station attitude 
and/or operations.
    (B) Where a space station requests the assignment of a geostationary 
orbit location, it must assess whether there are any known satellites 
located at, or reasonably expected to be located at, the requested 
orbital location, or assigned in the vicinity of that location, such 
that the station keeping

[[Page 630]]

volumes of the respective satellites might overlap or touch. If so, the 
statement must include a statement as to the identities of those parties 
and the measures that will be taken to prevent collisions.
    (v) A statement addressing the trackability of the space station(s). 
Space station(s) operating in low-Earth orbit will be presumed trackable 
if each individual space station is 10 cm or larger in its smallest 
dimension, exclusive of deployable components. Where the application is 
for an NGSO space station or system, the statement shall also disclose 
the following:
    (A) How the operator plans to identify the space station(s) 
following deployment and whether space station tracking will be active 
or passive;
    (B) Whether, prior to deployment, the space station(s) will be 
registered with the 18th Space Control Squadron or successor entity; and
    (C) The extent to which the space station operator plans to share 
information regarding initial deployment, ephemeris, and/or planned 
maneuvers with the 18th Space Control Squadron or successor entity, 
other entities that engage in space situational awareness or space 
traffic management functions, and/or other operators.
    (vi) A statement disclosing planned proximity operations, if any, 
and addressing debris generation that will or may result from the 
proposed operations, including any planned release of debris, the risk 
of accidental explosions, the risk of accidental collision, and measures 
taken to mitigate those risks.
    (vii) A statement detailing the disposal plans for the space 
station, including the quantity of fuel--if any--that will be reserved 
for disposal maneuvers. In addition, the following specific provisions 
apply:
    (A) For geostationary orbit space stations, the statement must 
disclose the altitude selected for a disposal orbit and the calculations 
that are used in deriving the disposal altitude.
    (B) For space stations terminating operations in an orbit in or 
passing through the low-Earth orbit region below 2,000 km altitude, the 
statement must disclose whether the spacecraft will be disposed of 
either through atmospheric re-entry, specifying if direct retrieval of 
the spacecraft will be used. The statement must also disclose the 
expected time in orbit for the space station following the completion of 
the mission.
    (C) For space stations not covered by either paragraph 
(g)(1)(vii)(A) or (B) of this section, the statement must indicate 
whether disposal will involve use of a storage orbit or long-term 
atmospheric re-entry and rationale for the selected disposal plan.
    (D) For all NGSO space stations under paragraph (g)(1)(vii)(B) or 
(C) of this section, the following additional specific provisions apply:
    (1) The statement must include a demonstration that the probability 
of success of the chosen disposal method will be 0.9 or greater for any 
individual space station. For space station systems consisting of 
multiple space stations, the demonstration should include additional 
information regarding efforts to achieve a higher probability of 
success, with a goal, for large systems, of a probability of success for 
any individual space station of 0.99 or better. For space stations under 
paragraph (g)(1)(vii)(B) of this section that will be terminating 
operations in or passing through low-Earth orbit, successful disposal is 
defined as atmospheric re-entry of the spacecraft within 25 years or 
less following completion of the mission. For space stations under 
paragraph (g)(1)(vii)(C) of this section, successful disposal will be 
assessed on a case-by-case basis.
    (2) If planned disposal is by atmospheric re-entry, the statement 
must also include:
    (i) A disclosure indicating whether the atmospheric re-entry will be 
an uncontrolled re-entry or a controlled targeted reentry.
    (ii) An assessment as to whether portions of any individual 
spacecraft will survive atmospheric re-entry and impact the surface of 
the Earth with a kinetic energy in excess of 15 joules, and 
demonstration that the calculated casualty risk for an individual 
spacecraft using the NASA Debris Assessment Software or a higher 
fidelity assessment tool is less than 0.0001 (1 in 10,000).

Sec.  97.303  Frequency sharing requirements.

    The following paragraphs summarize the frequency sharing 
requirements that apply to amateur stations transmitting in the 
frequency bands specified in Sec.  97.301 of this part. Each frequency 
band allocated to the amateur service is designated as either a 
secondary service or a primary service. A station in a secondary service 
must not cause harmful interference to, and must accept interference 
from, stations in a primary service.
    (a) Where, in adjacent ITU Regions or sub-Regions, a band of 
frequencies is allocated to different services of the same category 
(i.e., primary or secondary services), the basic principle is the 
equality of right to operate. Accordingly, stations of each service in 
one Region or sub-Region must operate so as not to cause harmful 
interference to any service of the same or higher category in the other 
Regions or sub-Regions.
    (b) Amateur stations transmitting in the 70 cm band, the 33 cm band, 
the 23 cm band, the 5 cm band, the 3 cm band, or the 24.05-24.25 GHz 
segment must not cause harmful interference to, and must accept 
interference from, stations authorized by the United States Government 
in the radiolocation service.
    (c) Amateur stations transmitting in the 76-81 GHz segment, the 136-
141 GHz segment, or the 241-248 GHz segment must not cause harmful 
interference to, and must accept interference from, stations authorized 
by the United States Government, the FCC, or other nations in the 
radiolocation service.
    (d) Amateur stations transmitting in the 430-450 MHz segment, the 23 
cm band, the 3.3-3.4 GHz segment, the 5.65-5.85 GHz segment, the 13 cm 
band, or the 24.05-24.25 GHz segment, must not cause harmful 
interference to, and must accept interference from, stations authorized 
by other nations in the radiolocation service.
    (e) Amateur stations receiving in the 33 cm band, the 2400-2450 MHz 
segment, the 5.725-5.875 GHz segment, the 1.2 cm band, the 2.5 mm band, 
or the 244-246 GHz segment must accept interference from industrial, 
scientific, and medical (ISM) equipment.
    (f) Amateur stations transmitting in the following segments must not 
cause harmful interference to radio astronomy stations: 76-81 GHz, 136-
141 GHz, 241-248 GHz, 275-323 GHz, 327-371 GHz, 388-424 GHz, 426-442 
GHz, 453-510 GHz, 623-711 GHz, 795-909 GHz, or 926-945 GHz. In addition, 
amateur stations transmitting in the following segments must not cause 
harmful interference to stations in the Earth exploration-satellite 
service (passive) or the space research service (passive): 275-286 GHz, 
296-306 GHz, 313-356 GHz, 361-365 GHz, 369-392 GHz, 397-399 GHz, 409-411 
GHz, 416-434 GHz, 439-467 GHz, 477-502 GHz, 523-527 GHz, 538-581 GHz, 
611-630 GHz, 634-654 GHz, 657-692 GHz, 713-718 GHz, 729-733 GHz, 750-754 
GHz, 771-776 GHz, 823-846 GHz, 850-854 GHz, 857-862 GHz, 866-882 GHz, 
905-928 GHz, 951-956 GHz, 968-973 GHz and 985-990 GHz.
    (g) In the 2200 m and 630 m bands:
    (1) Amateur stations in the 135.7-137.8 kHz (2200 m) and 472-479 kHz

[[Page 637]]

bands shall only operate at fixed locations. Amateur stations shall not 
operate within a horizontal distance of one kilometer from a 
transmission line that conducts a power line carrier (PLC) signal in the 
135.7-137.8 kHz or 472-479 kHz bands. Horizontal distance is measured 
from the station's antenna to the closest point on the transmission 
line.
    (2) Prior to commencement of operations in the 135.7-137.8 kHz (2200 
m) and/or 472-479 kHz (630 m) bands, amateur operators shall notify the 
Utilities Telecom Council (UTC) of their intent to operate by submitting 
their call signs, intended band or bands of operation, and the 
coordinates of their antenna's fixed location. Amateur stations will be 
permitted to commence operations after the 30-day period unless UTC 
notifies the station that its fixed location is located within one 
kilometer of PLC systems operating in the same or overlapping 
frequencies.
    (3) Amateur stations in the 135.7-137.8 kHz (2200 m) band shall not 
cause harmful interference to, and shall accept interference from:
    (i) Stations authorized by the United States Government in the fixed 
and maritime mobile services;
    (ii) Stations authorized by other nations in the fixed, maritime 
mobile, and radionavigation service.
    (4) Amateur stations in the 472-479 kHz (630 m) band shall not cause

    (ii) Stations authorized by other nations in the maritime mobile and 
aeronautical radionavigation services.
    (5) Amateur stations causing harmful interference shall take all 
necessary measures to eliminate such interference--including temporary 
or permanent termination of transmissions.
    (h) 60 m band: (1) In the 5330.5-5406.4 kHz band (60 m band), 
amateur stations may transmit only on the five center frequencies 
specified in the table below. In order to meet this requirement, control 
operators of stations transmitting phone, data, and RTTY emissions 
(emission designators 2K80J3E, 2K80J2D, and 60H0J2B, respectively) may 
set the carrier frequency 1.5 kHz below the center frequency as 
specified in the table below. For CW emissions (emission designator 
150HA1A), the carrier frequency is set to the center frequency. Amateur 
operators shall ensure that their emissions do not occupy more than 2.8 
kHz centered on each of these center frequencies.

§ 97.307  Emission standards.

    (a) No amateur station transmission shall occupy more bandwidth than 
necessary for the information rate and emission type being transmitted, 
in accordance with good amateur practice.
    (b) Emissions resulting from modulation must be confined to the band 
or segment available to the control operator. Emissions outside the 
necessary bandwidth must not cause splatter or keyclick interference to 
operations on adjacent frequencies.
    (c) All spurious emissions from a station transmitter must be 
reduced to the greatest extent practicable. If any spurious emission, 
including chassis or power line radiation, causes harmful interference 
to the reception of another radio station, the licensee of the 
interfering amateur station is required to take steps to eliminate the 
interference, in accordance with good engineering practice.
    (d) For transmitters installed after January 1, 2003, the mean power 
of any spurious emission from a station transmitter or external RF power 
amplifier transmitting on a frequency below 30 MHz must be at least 43 
dB below the mean power of the fundamental emission. For transmitters 
installed on or before January 1, 2003, the mean power of any spurious 
emission from a station transmitter or external RF power amplifier 
transmitting on a frequency below 30 MHz must not exceed 50 mW and must 
be at least 40 dB below the mean power of the fundamental emission. For 
a transmitter of mean power less than 5 W installed on or before January 
1, 2003, the attenuation must be at least 30 dB. A transmitter built 
before April 15, 1977, or first marketed before January 1, 1978, is 
exempt from this requirement.
    (e) The mean power of any spurious emission from a station 
transmitter or external RF power amplifier transmitting on a frequency 
between 30-225 MHz must be at least 60 dB below the mean power of the 
fundamental. For a transmitter having a mean power of 25 W or less, the 
mean power of any spurious emission supplied to the antenna transmission 
line must not exceed 25 [micro]W and must be at least 40 dB below the 
mean power of the fundamental emission, but

[[Page 641]]

need not be reduced below the power of 10 [micro]W. A transmitter built 
before April 15, 1977, or first marketed before January 1, 1978, is 
exempt from this requirement.
    (f) The following standards and limitations apply to transmissions 
on the frequencies specified in Sec.  97.305(c) of this part.
    (1) No angle-modulated emission may have a modulation index greater 
than 1 at the highest modulation frequency.
    (2) No non-phone emission shall exceed the bandwidth of a 
communications quality phone emission of the same modulation type. The 
total bandwidth of an independent sideband emission (having B as the 
first symbol), or a multiplexed image and phone emission, shall not 
exceed that of a communications quality A3E emission.
    (3) Only a RTTY or data emission using a specified digital code 
listed in Sec.  97.309(a) of this part may be transmitted. The symbol 
rate must not exceed 300 bauds, or for frequency-shift keying, the 
frequency shift between mark and space must not exceed 1 kHz.
    (4) Only a RTTY or data emission using a specified digital code 
listed in Sec.  97.309(a) of this part may be transmitted. The symbol 
rate must not exceed 1200 bauds, or for frequency-shift keying, the 
frequency shift between mark and space must not exceed 1 kHz.
    (5) A RTTY, data or multiplexed emission using a specified digital 
code listed in Sec.  97.309(a) of this part may be transmitted. The 
symbol rate must not exceed 19.6 kilobauds. A RTTY, data or multiplexed 
emission using an unspecified digital code under the limitations listed 
in Sec.  97.309(b) of this part also may be transmitted. The authorized 
bandwidth is 20 kHz.
    (6) A RTTY, data or multiplexed emission using a specified digital 
code listed in Sec.  97.309(a) of this part may be transmitted. The 
symbol rate must not exceed 56 kilobauds. A RTTY, data or multiplexed 
emission using an unspecified digital code under the limitations listed 
in Sec.  97.309(b) of this part also may be transmitted. The authorized 
bandwidth is 100 kHz.
    (7) A RTTY, data or multiplexed emission using a specified digital 
code listed in Sec.  97.309(a) of this part or an unspecified digital 
code under the limitations listed in Sec.  97.309(b) of this part may be 
transmitted.
    (8) A RTTY or data emission having designators with A, B, C, D, E, 
F, G, H, J or R as the first symbol; 1, 2, 7, 9 or X as the second 
symbol; and D or W as the third symbol is also authorized.
    (9) A station having a control operator holding a Novice or 
Technician Class operator license may only transmit a CW emission using 
the international Morse code.
    (10) A station having a control operator holding a Novice Class 
operator license or a Technician Class operator license may only 
transmit a CW emission using the international Morse code or phone 
emissions J3E and R3E.
    (11) Phone and image emissions may be transmitted only by stations 
located in ITU Regions 1 and 3, and by stations located within ITU 
Region 2 that are west of 130[deg] West longitude or south of 20[deg] 
North latitude.
    (12) Emission F8E may be transmitted.
    (13) A data emission using an unspecified digital code under the 
limitations listed in Sec.  97.309(b) also may be transmitted. The 
authorized bandwidth is 100 kHz.
    (14) In the 60 m band:
    (i) A station may transmit only phone, RTTY, data, and CW emissions 
using the emission designators and any additional restrictions that are 
specified in the table below (except that the use of a narrower 
necessary bandwidth is permitted):

Sec.  97.309  RTTY and data emission codes.

    (a) Where authorized by Sec. Sec.  97.305(c) and 97.307(f) of the 
part, an amateur station may transmit a RTTY or data emission using the 
following specified digital codes:
    (1) The 5-unit, start-stop, International Telegraph Alphabet No. 2, 
code defined in ITU-T Recommendation F.1, Division C (commonly known as 
``Baudot'').
    (2) The 7-unit code specified in ITU-R Recommendations M.476-5 and 
M.625-3 (commonly known as ``AMTOR'').
    (3) The 7-unit, International Alphabet No. 5, code defined in IT--T 
Recommendation T.50 (commonly known as ``ASCII'').
    (4) An amateur station transmitting a RTTY or data emission using a 
digital code specified in this paragraph may use any technique whose 
technical characteristics have been documented publicly, such as CLOVER, 
G-TOR, or PacTOR, for the purpose of facilitating communications.
    (b) Where authorized by Sec. Sec.  97.305(c) and 97.307(f), a 
station may transmit a RTTY or data emission using an unspecified 
digital code, except to a station in a country with which the United 
States does not have an agreement permitting the code to be used. RTTY 
and data emissions using unspecified digital codes must not be 
transmitted for the purpose of obscuring the meaning of any 
communication. When deemed necessary by a Regional Director to assure 
compliance with the FCC Rules, a station must:
    (1) Cease the transmission using the unspecified digital code;
    (2) Restrict transmissions of any digital code to the extent 
instructed;
    (3) Maintain a record, convertible to the original information, of 
all digital communications transmitted.

Sec.  97.311  SS emission types.

    (a) SS emission transmissions by an amateur station are authorized 
only for communications between points within areas where the amateur 
service is regulated by the FCC and between an area where the amateur 
service is regulated by the FCC and an amateur station in another 
country that permits such communications. SS emission transmissions must 
not be used for the purpose of obscuring the meaning of any 
communication.
    (b) A station transmitting SS emissions must not cause harmful 
interference to stations employing other authorized emissions, and must 
accept all interference caused by stations employing other authorized 
emissions.
    (c) When deemed necessary by a Regional Director to assure 
compliance with this part, a station licensee must:
    (1) Cease SS emission transmissions;
    (2) Restrict SS emission transmissions to the extent instructed; and
    (3) Maintain a record, convertible to the original information 
(voice, text, image, etc.) of all spread spectrum communications

Sec.  97.313  Transmitter power standards.

    (a) An amateur station must use the minimum transmitter power 
necessary to carry out the desired communications.
    (b) No station may transmit with a transmitter power exceeding 1.5 
kW PEP.
    (c) No station may transmit with a transmitter power output 
exceeding 200 W PEP:
    (1) On the 10.10-10.15 MHz segment;

[[Page 643]]

    (2) On the 3.525-3.60 MHz, 7.025-7.125 MHz, 21.025-21.20 MHz, and 
28.0-28.5 MHz segment when the control operator is a Novice Class 
operator or a Technician Class operator; or
    (3) The 7.050-7.075 MHz segment when the station is within ITU 
Regions 1 or 3.
    (d) No station may transmit with a transmitter power exceeding 25 W 
PEP on the VHF 1.25 m band when the control operator is a Novice 
operator.
    (e) No station may transmit with a transmitter power exceeding 5 W 
PEP on the UHF 23 cm band when the control operator is a Novice 
operator.
    (f) No station may transmit with a transmitter power exceeding 50 W 
PEP on the UHF 70 cm band from an area specified in paragraph (a) of 
footnote US270 in Sec.  2.106, unless expressly authorized by the FCC 
after mutual agreement, on a case-by-case basis, between the Regional 
Director of the applicable field facility and the military area 
frequency coordinator at the applicable military base. An Earth station 
or telecommand station, however, may transmit on the 435-438 MHz segment 
with a maximum of 611 W effective radiated power (1 kW equivalent 
isotropically radiated power) without the authorization otherwise 
required. The transmitting antenna elevation angle between the lower 
half-power (-3 dB relative to the peak or antenna bore sight) point and 
the horizon must always be greater than 10[deg].
    (g) No station may transmit with a transmitter power exceeding 50 W 
PEP on the 33 cm band from within 241 km of the boundaries of the White 
Sands Missile Range. Its boundaries are those portions of Texas and New 
Mexico bounded on the south by latitude 31[deg]41[min] North, on the 
east by longitude 104[deg]11[min] West, on the north by latitude 
34[deg]30[min] North, and on the west by longitude 107[deg]30[min] West.
    (h) No station may transmit with a transmitter power exceeding 50 W 
PEP on the 219-220 MHz segment of the 1.25 m band.
    (i) No station may transmit with an effective radiated power (ERP) 
exceeding 100 W PEP on the 60 m band. For the purpose of computing ERP, 
the transmitter PEP will be multiplied by the antenna gain relative to a 
half-wave dipole antenna. A half-wave dipole antenna will be presumed to 
have a gain of 1 (0 dBd). Licensees using other antennas must maintain 
in their station records either the antenna manufacturer's data on the 
antenna gain or calculations of the antenna gain.
    (j) No station may transmit with a transmitter output exceeding 10 W 
PEP when the station is transmitting a SS emission type.
    (k) No station may transmit in the 135.7-137.8 kHz (2200 m) band 
with a transmitter power exceeding 1.5 kW PEP or a radiated power 
exceeding 1 W EIRP.
    (l) No station may transmit in the 472-479 kHz (630 m) band with a 
transmitter power exceeding 500 W PEP or a radiated power exceeding 5 W 
EIRP, except that in Alaska, stations located within 800 kilometers of 
the Russian Federation may not transmit with a radiated power exceeding 
1 W EIRP.

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).''

Sec.  101.21  Technical content of applications.

    Applications, except FCC Form 175, 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, J, and L 
of this part, as appropriate). The following paragraphs describe a 
number of technical requirements.
    (a)-(d) [Reserved]
    (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, its stability, effective isotropic radiated 
power, emission designator, and type of modulation (digital).
Transmitting antenna(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(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.

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, major 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

[[Page 659]]

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 Sec.  25.251 
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 
Space Bureau in Washington, DC.)
    (g) Each application in the Local Multipoint Distribution Service 
and 24 GHz Service must contain all technical information required by 
FCC Form 601 and any other applicable form or associated Public Notices

Sec.  101.31  Temporary and conditional authorizations.

    (a) Operation at temporary locations. (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 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 601. Blanket applications may be submitted for the required number 
of transmitters. An application for authority to operate a fixed station 
at temporary locations must specify the precise geographic area within 
which the operation will be confined. The area specified must be defined 
as a radius of operation about a specific coordinate (latitude/
longitude), or as a county, or as a State. Exception to this specific 
requirement may be made for exceptionally large areas, such as the 
continental United States. Sufficient data must be submitted to show the 
need for the proposed area of operation.
    (3) Operations in the 17.8-19.7 GHz band for any services and in the 
17.7-17.8 GHz band for MVPD operations are prohibited in the areas 
defined in Sec.  1.924 of this chapter. Operations proposed in the areas

                       Processing of Applications



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, except in the Local Multipoint 
Distribution Service and in the 24 GHz Service, will be entitled 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 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 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.  1.929 of this 
chapter), 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 of this part), and 
the Commission or the presiding officer accepts the amendment pursuant 
to Sec.  1.927 of this chapter;

[[Page 662]]

    (2) The amendment resolves frequency conflicts with authorized 
stations or other pending applications which would otherwise require 
resolution by hearing or by comparative evaluation pursuant to Sec.  
101.51 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.  1.935 of this chapter 
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 
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.  101.51  Comparative evaluation of mutually exclusive applications.

    (a) In order to expedite action on mutually exclusive applications 
in services under this rules part where neither competitive bidding nor 
the random selection processes 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

[[Page 663]]

    (3) The Commission determines, initially or at any time during the 
procedure outline 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 Sec.  1.915 of this chapter.
    (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.  101.55  Considerations involving transfer or assignment applications.

    (a) Except as provided for in paragraph (d) of this section, 
licenses not authorized pursuant to competitive bidding procedures may 
not be assigned or transferred prior to the completion of construction 
of the facility.
    (b) [Reserved]
    (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.
    (d) If a proposed transfer of radio facilities is incidental to a 
sale or other facilities or merger of interests, the showing specified 
under paragraph (c)

[[Page 664]]

of this section shall be submitted and 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.

Sec.  101.61  Certain modifications not requiring prior authorization 
in the Local Multipoint Distribution Service and 24 GHz Service

    In the Local Multipoint Distribution Service (LMDS) licensees may 
add, remove, or relocate facilities within the area authorized by the 
license without prior authorization. Upon request by an incumbent 
licensee or the Commission, an LMDS licensee shall furnish the technical 
parameters, location and coordinates of the completion of the addition, 
removal, relocation or modification of any of its facilities within the 
BTA. The LMDS licensee must provide such information within ten (10) 
days of receiving a written request. This section also applies to 24 GHz 
licensees that are licensed according to Economic Areas.

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

    (a) Each Station, except in Multichannel Video Distribution and Data 
Service, Local Multipoint Distribution Service, and the 24 GHz Service, 
authorized under this part must be in operation within 18 months from 
the initial date of grant.
    (b) For the 70 GHz, 80 GHz, and 90 GHz bands, the 12-month 
construction period will commence on the date of each registration of 
each individual link; adding links will not change the overall renewal 
period of the license.
    (c) Failure to timely begin operation means the authorization 
cancels automatically.
    (d) 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. See 
Sec.  101.1331(d) for treatment of MAS incumbent site-by-site licenses 
recovered in EAs.
    (e) Requests for extension of time may be granted upon a showing of 
good cause pursuant to Sec.  1.946(e) of this chapter.
    (f) Construction of any authorized facility or frequency must be 
completed by the date specified in the license as pursuant to Sec.  
1.946 of this chapter.
    (g) MVPD licensees which have both analog and digital emissions 
designators specified on the license and which already have, or may 
transition from analog to digital operations, or a combination of both, 
meet their completion of construction requirements and do not 
automatically surrender their license provided they are using either set 
of emissions. If the licensee has completed the transition to digital, 
the license can remove the unused analog emission designators the next 
time a modification or renewal application is filed.

Sec.  101.64  Service areas.

    Service areas for 38.6-40.0 GHz service are Economic Areas (EAs) as 
defined below. EAs are delineated by the Regional Economic Analysis 
Division, Bureau of Economic Analysis, U.S. Department of Commerce. The 
Commerce Department organizes the 50 States and the District of Columbia 
into 172 EAs. Additionally, there are four EA-like areas: Guam and 
Northern Mariana Islands; Puerto Rico and the U.S.

[[Page 665]]

Virgin Islands; American Samoa and the Gulf of Mexico. A total of 175 
authorizations (excluding the Gulf of Mexico EA-like area) will be 
issued for each channel block in the 39 GHz band.

Sec.  101.65  Termination of station authorizations.

    In addition to the provisions of Sec.  1.953 of this chapter, a 
site-based license will be automatically terminated in whole or in part 
without further notice to the licensee upon the voluntary removal or 
alteration of the facilities, so as to render the station not 
operational for a period of 30 days or more. A licensee is subject to 
this provision commencing on the date it is required to be providing 
service or operating under Sec.  101.63. This provision is inapplicable 
to blanket authorizations to operate fixed stations at temporary 
locations pursuant to the provisions of Sec.  101.31(a)(2). See Sec.  
101.305 for additional rules regarding temporary and permanent 
discontinuation of service.

    Effective Date Note: At 82 FR 41549, Sept. 1, 2017, Sec.  101.65 was 
revised. This section contains information collection and recordkeeping 
requirements and will not become effective until approval has been given 
by the Office of Management and Budget.



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.

Policies Governing Microwave Relocation From the 1850-1990 and 2110-2200 
                                MHz Bands



Sec.  101.69  Transition of the 1850-1990 MHz, 2110-2150 MHz, 
and 2160-2200 MHz bands from the fixed microwave services to personal 
communications services and emerging technologies.

    Fixed Microwave Services (FMS) in the 1850-1990 MHz, 2110-2150 MHz, 
and 2160-2200 MHz bands have been allocated for use by emerging 
technology (ET) services, including Personal Communications Services 
(PCS), Advanced Wireless Services (AWS), and Mobile Satellite Services 
(MSS). The rules in this section provide for a transition period during 
which ET licensees may relocate existing FMS licensees using these 
frequencies to other media or other fixed channels, including those in 
other microwave bands.
    (a) ET licensees may negotiate with FMS licensees authorized to use 
frequencies in the 1850-1990 MHz, 2110-2150 MHz, and 2160-2200 MHz 
bands, for the purpose of agreeing to terms under which the FMS 
licensees would:
    (1) Relocate their operations to other fixed microwave bands or 
other media; or alternatively
    (2) Accept a sharing arrangement with the ET licensee that may 
result in an otherwise impermissible level of interference to the FMS 
operations.
    (b)-(c) [Reserved]
    (d) Relocation of FMS licensees in the 2110-2150 and 2160-2200 MHz 
band will be subject to mandatory negotiations only. Except as provided 
in paragraph (e) of this section, mandatory negotiation periods are 
defined as follows:
    (1) Non-public safety incumbents will have a two-year mandatory 
negotiation period; and
    (2) Public safety incumbents will have a three-year mandatory 
negotiation period.
    (e) Relocation of FMS licensees by Mobile-Satellite Service (MSS) 
licensees will be subject to mandatory negotiations only.
    (1) The mandatory negotiation period for non-public safety 
incumbents will end December 8, 2004.
    (2) The mandatory negotiation period for public safety incumbents 
will end December 8, 2005.
    (f) AWS licensees operating in the 1910-1920 MHz and 2175-2180 MHz 
bands will follow the requirements and procedures set forth in ET Docket 
No. 00-258 and WT Docket No. 04-356.
    (g) If no agreement is reached during the mandatory negotiation 
period, an ET licensee may initiate involuntary relocation procedures. 
Under involuntary relocation, the incumbent is required to relocate, 
provided that the

[[Page 666]]

ET licensee meets the conditions of Sec.  101.75.

Sec.  101.71  [Reserved]



Sec.  101.73  Mandatory negotiations.

    (a) A mandatory negotiation period may be initiated at the option of 
the ET licensee. Relocation of FMS licensees by Mobile Satellite Service 
(MSS) operators and AWS licensees in the 2110-2150 MHz and 2160-2200 MHz 
bands will be subject to mandatory negotiations only.
    (b) Once mandatory negotiations have begun, an FMS licensee may not 
refuse to negotiate and all parties are required to negotiate in good 
faith. Good faith requires each party to provide information to the 
other that is reasonably necessary to facilitate the relocation process. 
In evaluating claims that a party has not negotiated in good faith, the 
FCC will consider, inter alia, the following factors:
    (1) Whether the ET licensee has made a bona fide offer to relocate 
the FMS licensee to comparable facilities in accordance with Section 
101.75(b);
    (2) If the FMS licensee has demanded a premium, the type of premium 
requested (e.g., whether the premium is directly related to relocation, 
such as system-wide relocations and analog-to-digital conversions, 
versus other types of premiums), and whether the value of the premium as 
compared to the cost of providing comparable facilities is 
disproportionate (i.e., whether there is a lack of proportion or 
relation between the two);
    (3) What steps the parties have taken to determine the actual cost 
of relocation to comparable facilities;
    (4) Whether either party has withheld information requested by the 
other party that is necessary to estimate relocation costs or to 
facilitate the relocation process.
    (c) Any party alleging a violation of our good faith requirement 
must attach an independent estimate of the relocation costs in question 
to any documentation filed with the Commission in support of its claim. 
An independent cost estimate must include a specification for the 
comparable facility and a statement of the costs associated with 
providing that facility to the incumbent licensee.
    (d) Provisions for Relocation of Fixed Microwave Licensees in the 
2110-2150 and 2160-2200 MHz bands. A separate mandatory negotiation 
period will commence for each FMS licensee when an ET licensee informs 
that FMS licensee in writing of its desire to negotiate. Mandatory 
negotiations will be conducted with the goal of providing the FMS 
licensee with comparable facilities defined as facilities possessing the 
following characteristics:
    (1) Throughput. Communications throughput is the amount of 
information transferred within a system in a given amount of time. If 
analog facilities are being replaced with analog, comparable facilities 
provide an equivalent number of 4 kHz voice channels. If digital 
facilities are being replaced with digital, comparable facilities 
provide equivalent data loading bits per second (bps).
    (2) Reliability. System reliability is the degree to which 
information is transferred accurately within a system. Comparable 
facilities provide reliability equal to the overall reliability of the 
FMS system. For digital systems, reliability is measured by the percent 
of time the bit error rate (BER) exceeds a desired value, and for analog 
or digital voice transmission, it is measured by the percent of time 
that audio signal quality meets an established threshold. If an analog 
system is replaced with a digital system, only the resulting frequency 
response, harmonic distortion, signal-to-noise and its reliability will 
be considered in determining comparable reliability.
    (3) Operating Costs. Operating costs are the cost to operate and 
maintain the FMS system. ET licensees would compensate FMS licensees for 
any increased recurring costs associated with the replacement facilities 
(e.g., additional rental payments, and increased utility fees) for five 
years after relocation. ET licensees could satisfy this obligation by 
making a lump-sum payment based on present value using current interest 
rates. Additionally, the

[[Page 667]]

maintenance costs to the FMS licensee would be equivalent to the 2 GHz 
system in order for the replacement system to be comparable.

Sec.  101.75  Involuntary relocation procedures.

    (a) If no agreement is reached during the mandatory negotiation 
period, an ET licensee may initiate involuntary relocation procedures 
under the Commission's rules. ET licensees are obligated to pay to 
relocated only the specific microwave links to which their systems pose 
an interference problem. Under involuntary relocation, the FMS licensee 
is required to relocate, provided that the ET licensee:
    (1) Guarantees payment of relocation costs, including all 
engineering, equipment, site and FCC fees, as well as any legitimate and 
prudent transaction expenses incurred by the FMS licensee that are 
directly attributable to an involuntary relocation, subject to a cap of 
two percent of the hard costs involved. Hard costs are defined as the 
actual costs associated with providing a replacement system, such as 
equipment and engineering expenses. ET licensees are not required to pay 
FMS licensees for internal resources devoted to the relocation process. 
ET licensees are not required to pay for transaction costs incurred by 
FMS licensees during the voluntary or mandatory periods once the 
involuntary period is initiated, or for fees that cannot be legitimately 
tied to the provision of comparable facilities;
    (2) 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) Builds the replacement system and tests it for comparability 
with the existing 2 GHz system.
    (b) Comparable facilities. The replacement system provided to an 
incumbent during an involuntary relocation must be at least equivalent 
to the existing FMS system with respect to the following three factors:
    (1) Throughput. Communications throughput is the amount of 
information transferred within a system in a given amount of time. If 
analog facilities are being replaced with analog, the ET licensee is 
required to provide the FMS licensee with an equivalent number of 4 kHz 
voice channels. If digital facilities are being replaced with digital, 
the ET licensee must provide the FMS licensee with equivalent data 
loading bits per second (bps). ET licensees must provide FMS licensees 
with enough throughput to satisfy the FMS licensee's system use at the 
time of relocation, not match the total capacity of the FMS system.
    (2) Reliability. System reliability is the degree to which 
information is transferred accurately within a system. ET licensees must 
provide FMS licensees with reliability equal to the overall reliability 
of their system. For digital data systems, reliability is measured by 
the percent of time the bit error rate (BER) exceeds a desired value, 
and for analog or digital voice transmissions, it is measured by the 
percent of time that audio signal quality meets an established 
threshold. If an analog voice system is replaced with a digital voice 
system, only the resulting frequency response, harmonic distortion, 
signal-to-noise ratio and its reliability will be considered in 
determining comparable reliability.
    (3) Operating costs. Operating costs are the cost to operate and 
maintain the FMS system. ET licensees must compensate FMS licensees for 
any increased recurring costs associated with the replacement facilities 
(e.g., additional rental payments, increased utility fees) for five 
years after relocation. ET licensees may satisfy this obligation by 
making a lump-sum payment based on present value using current interest 
rates. Additionally, the maintenance costs to the FMS licensee must be 
equivalent to the 2 GHz system in order for the replacement system to be 
considered comparable.

[[Page 668]]

    (c) The FMS 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.
    (d) Twelve-month trial period. If, within one year after the 
relocation to new facilities, the FMS licensee demonstrates that the new 
facilities are not comparable to the former facilities, the ET licensee 
must remedy the defects or pay to relocate the microwave licensee to one 
of the following: its former or equivalent 2 GHz channels, another 
comparable frequency band, a land-line system, or any other facility 
that satisfies the requirements specified in paragraph (b) of this 
section. This trial period commences on the date that the FMS licensee 
begins full operation of the replacement link. If the FMS licensee has 
retained its 2 GHz authorization during the trial period, it must return 
the license to the Commission at the end of the twelve months. FMS 
licensees relocated from the 2110-2150 and 2160-2200 MHz bands may not 
be returned to their former 2 GHz channels. All other remedies specified 
in paragraph (d) are available to FMS licensees relocated from the 2110-
2150 MHz and 2160-2200 MHz bands, and may be invoked whenever the FMS 
licensee demonstrates that its replacement facility is not comparable, 
subject to no time limit.

Sec.  101.77  Public safety licensees in the 1850-1990 MHz, 2110-2150 MHz, 
and 2160-2200 MHz bands.

    (a) In order for public safety licensees to qualify for a three year 
mandatory negotiation period as defined in Sec.  101.69(d)(2), the 
department head responsible for system oversight must certify to the ET 
licensee requesting relocation that:
    (1) The agency is a Police licensee, a Fire Licensee, or an 
Emergency Medical Licensee as defined in Sec.  90.7 of this chapter, or 
meets the eligibility requirements of Sec.  90.20(a)(2) of this chapter, 
except for Sec.  90.20(a)(2)(ii) of this chapter, or that it is a 
licensee of other part 101 facilities licensed on a primary basis under 
the eligibility requirements of part 90, subpart B of this chapter; and
    (2) The majority of communications carried on the facilities at 
issue involve safety of life and property.
    (b) A public safety licensee must provide certification within 
thirty (30) days of a request from a ET licensee, or the ET licensee may 
presume that special treatment is inapplicable. If a public safety 
licensee falsely certifies to an ET licensee that it qualifies for the 
extended time periods, this licensee will be in violation of the 
Commission's rules and will subject to appropriate penalties, as well as 
immediately subject to the non-public safety time periods.

Sec.  101.79  Sunset provisions for licensees in the 1850-1990 MHz, 
2110-2150 MHz, and 2160-2200 MHz bands.

    (a) FMS licensees will maintain primary status in the 1850-1990 MHz, 
2110-2150 MHz, and 2160-2200 MHz bands unless and until an ET licensee 
requires use of the spectrum. ET licensees are not required to pay 
relocation costs after the relocation rules sunset. Once the relocation 
rules sunset, an ET licensee may require the incumbent to cease 
operations, provided that the ET licensee intends to turn on a system 
within interference range of the incumbent, as determined by TIA TSB 10-
F (for terrestrial-to-terrestrial situations) or TIA TSB 86 (for MSS 
satellite-to-terrestrial situations) or any standard successor. ET 
licensee notification to the affected FMS licensee must be in writing 
and must provide the incumbent with no less than six months to vacate 
the spectrum. After the six-month notice period has expired, the FMS 
licensee must turn its license back into the Commission, unless the 
parties have entered into an agreement which allows the FMS licensee to 
continue to operate on a mutually agreed upon basis. The date that the 
relocation rules sunset is determined as follows:
    (1) For the 2110-2150 MHz and 2160-2175 MHz and 2175-2180 MHz bands, 
ten

[[Page 669]]

years after the first ET license is issued in the respective band; and
    (2) For the 2180-2200 MHz band, for MSS/ATC December 8, 2013 (i.e., 
ten years after the mandatory negotiation period begins for MSS/ATC 
operators in the service), and for ET licensees authorized under part 27 
ten years after the first part 27 license is issued in the band. To the 
extent that an MSS operator is also an ET licensee authorized under part 
27, the part 27 sunset applies to its relocation and cost sharing 
obligations should the two sets of obligations conflict.
    (b) If the parties cannot agree on a schedule or an alternative 
arrangement, requests for extension will be accepted and reviewed on a 
case-by-case basis. The Commission will grant such extensions only if 
the incumbent can demonstrate that:
    (1) It cannot relocate within the six-month period (e.g., because no 
alternative spectrum or other reasonable option is available), and;
    (2) The public interest would be harmed if the incumbent is forced 
to terminate operations (e.g., if public safety communications services 
would be disrupted).

Sec.  101.81  Future licensing in the 1850-1990 MHz, 2110-2150 MHz, 
and 2160-2200 MHz bands.

    After April 25, 1996, all major modifications and extensions to 
existing FMS systems in the 1850-1990 MHz, 2110-2150 MHz, and 2160-2200 
MHz bands will be authorized on a secondary basis to ET systems. All 
other modifications will render the modified FMS license secondary to ET 
operations, unless the incumbent affirmatively justifies primary status 
and the incumbent FMS licensee establishes that the modification would 
not add to the relocation costs of ET licensees. Incumbent FMS licensees 
will maintain primary status for the following technical changes:
    (a) Decreases in power;
    (b) Minor changes (increases or decreases) in antenna height;
    (c) Minor location changes (up to two seconds);
    (d) Any data correction which does not involve a change in the 
location of an existing facility;
    (e) Reductions in authorized bandwidth;
    (f) Minor changes (increases or decreases) in structure height;
    (g) Changes (increases or decreases) in ground elevation that do not

Sec.  101.82  Reimbursement and relocation expenses in the 2110-2150 MHz 
and 2160-2200 MHz bands.

    (a) Reimbursement and relocation expenses for the 2110-2130 MHz and 
2160-2200 MHz bands are addressed in Sec. Sec.  27.1160-27.1174.
    (b) Cost-sharing obligations between AWS and MSS (space-to-Earth 
downlink). Whenever an ET licensee (AWS or Mobile Satellite Service for 
space-to-Earth downlink in the 2130-2150 or 2180-2200 MHz bands) 
relocates an incumbent paired microwave link with one path in the 2130-
2150 MHz band and the paired path in the 2180-2200 MHz band, the 
relocator is entitled to reimbursement of 50 percent of its relocation 
costs (see paragraph (e)) of this section from any other AWS licensee or 
MSS space-to-Earth downlink operator which would have been required to 
relocate the same fixed microwave link as set forth in paragraphs (c) 
and (d) of this section.
    (c) Cost-sharing obligations for MSS (space-to-Earth downlinks). For 
an MSS space-to-Earth downlink, the cost-sharing obligation is based on 
the interference criteria for relocation, i.e., TIA TSB 86 or any 
standard successor, relative to the relocated microwave link. 
Subsequently entering MSS space-to-Earth downlink operators must 
reimburse AWS or MSS space-to-Earth relocators (see paragraph (e)) of 
this section before the later entrant may begin operations in these 
bands, unless the later entrant can demonstrate that it would not have 
interfered with the microwave link in question.
    (d) Cost-sharing obligations among terrestrial stations. For 
terrestrial stations

[[Page 670]]

(AWS), cost-sharing obligations are governed by Sec. Sec.  27.1160 
through 27.1174 of this chapter; provided, however, that MSS operators 
are not obligated to reimburse voluntarily relocating FMS incumbents in 
the 2180-2200 MHz band. (AWS reimbursement and cost-sharing obligations 
relative to voluntarily relocating FMS incumbents are governed by Sec.  
27.1166 of this chapter).
    (e) The total costs of which 50 percent is to be reimbursed will not 
exceed $250,000 per paired fixed microwave link relocated, with an 
additional $150,000 permitted if a new or modified tower is required.

    Source: 65 FR 54173, Sept. 7, 2000, unless otherwise noted.



Sec.  101.83  Modification of station license.

    Permissible changes in equipment operating in the band 18.3-19.3 
GHz: Notwithstanding other provisions of this section, stations that 
remain co-primary under the provisions of Sec.  101.147(r) may not make 
modifications to their systems that increase interference to satellite 
earth stations, or result in a facility that would be more costly to 
relocate.

[68 FR 16968, Apr. 8, 2003]



Sec.  101.85  Transition of the 18.3-19.3 GHz band from the terrestrial 
fixed services to the fixed-satellite service (FSS).

    Fixed services (FS) frequencies in the 18.3-19.3 GHz bands listed in 
Sec. Sec.  21.901(e), 74.502(c), 74.602(g), and 78.18(a)(4) and Sec.  
101.147(a) and (r) of this chapter have been allocated for use by the 
fixed-satellite service (FSS). The rules in this section provide for a 
transition period during which FSS licensees may relocate existing FS 
licensees using these frequencies to other frequency bands, media or 
facilities.
    (a) FSS licensees may negotiate with FS licensees authorized to use 
frequencies in the 18.3-19.30 GHz bands for the purpose of agreeing to 
terms under which the FS licensees would:
    (1) Relocate their operations to other frequency bands, media or 
facilities; or alternatively
    (2) Accept a sharing arrangement with the FSS licensee that may 
result in an otherwise impermissible level of interference to the FSS 
operations.
    (b)(1) FS operations in the 18.3-18.58 GHz band that remain co-
primary under the provisions of Sec. Sec.  21.901(e), 74.502(c), 
74.602(d), 78.18(a)(4) and 101.147(r) of this chapter will continue to 
be co-primary with the FSS users of this spectrum until November 19, 
2012 or until the relocation of the fixed service operations, whichever 
occurs sooner.
    (2) FS operations in the 18.58-19.3 GHz band that remain co-primary 
under the provisions of Sec. Sec.  21.901(e), 74.502(c), 74.602(d), 
78.18(a)(4) and 101.147(r) of this chapter will continue to be co-
primary with the FSS users of this spectrum until June 8, 2010 or until 
the relocation of the fixed service operations, whichever occurs sooner, 
except for operations in the band 19.26-19.3 GHz and low power systems 
operating pursuant to Sec.  101.47(r)(10), which shall operate on a co-
primary basis until October 31, 2011.
    (3) If no agreement is reached during the negotiations pursuant to 
Sec.  101.85(a), an FSS licensee may initiate relocation procedures. 
Under the relocation procedures, the incumbent is required to relocate, 
provided that the FSS licensee meets the conditions of Sec.  101.91.
    (c) Negotiation periods are defined as follows:
    (1) Non-public safety incumbents will have a two-year negotiation 
period.
    (2) Public safety incumbents will have a three-year negotiation 
period.

[65 FR 54173, Sept. 7, 2000, as amended at 66 FR 63516, Dec. 7, 2001; 68 
FR 16968, Apr. 8, 2003]



Sec.  101.89  Negotiations.

    (a) The negotiation is triggered by the fixed-satellite service 
(FSS) licensee, who must contact the fixed services (FS) licensee and 
request that negotiations begin.

[[Page 671]]

    (b) Once negotiations have begun, an FS licensee may not refuse to 
negotiate and all parties are required to negotiate in good faith. Good 
faith requires each party to provide information to the other that is 
reasonably necessary to facilitate the relocation process. In evaluating 
claims that a party has not negotiated in good faith, the FCC will 
consider, inter alia, the following factors:
    (1) Whether the FSS licensee has made a bona fide offer to relocate 
the FS licensee to comparable facilities in accordance with Sec.  
101.91(b);
    (2) If the FS licensee has demanded a premium, the type of premium 
requested (e.g., whether the premium is directly related to relocation, 
such as system-wide relocations and analog-to-digital conversions, 
versus other types of premiums), and whether the value of the premium as 
compared to the cost of providing comparable facilities is 
disproportionate (i.e., whether there is a lack of proportion or 
relation between the two);
    (3) What steps the parties have taken to determine the actual cost 
of relocation to comparable facilities;
    (4) Whether either party has withheld information requested by the 
other party that is necessary to estimate relocation costs or to 
facilitate the relocation process.
    (c) Any party alleging a violation of our good faith requirement 
must attach an independent estimate of the relocation costs in question 
to any documentation filed with the Commission in support of its claim. 
An independent cost estimate must include a specification for the 
comparable facility and a statement of the costs associated with 
providing that facility to the incumbent licensee.
    (d) Negotiations will commence when the FSS licensee informs the FS 
licensee in writing of its desire to negotiate. Negotiations will be 
conducted with the goal of providing the FS licensee with comparable 
facilities, defined as facilities possessing the following 
characteristics:
    (1) Throughput. Communications throughput is the amount of 
information transferred within a system in a given amount of time. If 
analog facilities are being replaced with analog, the FSS licensee is 
required to provide the FS licensee with an equivalent number of 4 kHz 
voice channels. If digital facilities are being replaced with digital, 
the FSS licensee must provide the FS licensee with equivalent data 
loading bits per second (bps). FSS licensees must provide FS licensees 
with enough throughput to satisfy the FS licensee's system use at the 
time of relocation, not match the total capacity of the FS system.
    (2) Reliability. System reliability is the degree to which 
information is transferred accurately within a system. FSS licensees 
must provide FS licensees with reliability equal to the overall 
reliability of their system. For digital data systems, reliability is 
measured by the percent of time the bit error rate (BER) exceeds a 
desired value, and for analog or digital voice transmissions, it is 
measured by the percent of time that audio signal quality meets an 
established threshold. If an analog voice system is replaced with a 
digital voice system, only the resulting frequency response, harmonic 
distortion, signal-to-noise ratio and its reliability will be considered 
in determining comparable reliability.
    (3) Operating costs. Operating costs are the cost to operate and 
maintain the FS system. FSS licensees must compensate FS licensees for 
any increased recurring costs associated with the replacement facilities 
(e.g., additional rental payments, increased utility fees) for five 
years after relocation. FSS licensees may satisfy this obligation by 
making a lump-sum payment based on present value using current interest 
rates. Additionally, the maintenance costs to the FS licensee must be 
equivalent to the 18 GHz system in order for the replacement system to 
be considered comparable.



Sec.  101.91  Involuntary relocation procedures.

    (a) If no agreement is reached during the negotiations period, an 
FSS licensee may initiate relocation procedures under the Commission's 
rules. FSS licensees are obligated to pay to relocate only the specific 
microwave

[[Page 672]]

links from which their systems may receive interference. Under these 
procedures, the FS licensee is required to relocate, provided that the 
FSS licensee:
    (1) Guarantees payment of relocation costs, including all 
engineering, equipment, site and FCC fees, as well as any legitimate and 
prudent transaction expenses incurred by the FS licensee that are 
directly attributable to the relocation, subject to a cap of two percent 
of the hard costs involved. Hard costs are defined as the actual costs 
associated with providing a replacement system, such as equipment and 
engineering expenses. FSS licensees are not required to pay FS licensees 
for internal resources devoted to the relocation process. FSS licensees 
are not required to pay for transaction costs incurred by FS licensees 
during the negotiations once the negotiation is initiated, or for fees 
that cannot be legitimately tied to the provision of comparable 
facilities;
    (2) Completes all activities necessary for implementing the 
replacement facilities, including engineering and cost analysis of the 
relocation procedure and, if radio facilities are used, identifying and 
obtaining, on the incumbents' behalf, new microwave frequencies and 
frequency coordination; and
    (3) Builds the replacement system and tests it for comparability 
with the existing 18 GHz system.
    (b) Comparable facilities. The replacement system provided to an 
incumbent during a relocation must be at least equivalent to the 
existing FS system with respect to the following three factors:
    (1) Throughput. Communications throughput is the amount of 
information transferred within a system in a given amount of time. If 
analog facilities are being replaced with analog, the FSS licensee is 
required to provide the FS licensee with an equivalent number of 4 kHz 
voice channels. If digital facilities are being replaced with digital, 
the FSS licensee must provide the FS licensee with equivalent data 
loading bits per second (bps). FSS licensees must provide FS licensees 
with enough throughput to satisfy the FS licensee's system use at the 
time of relocation, not match the total capacity of the FS system.
    (2) Reliability. System reliability is the degree to which 
information is transferred accurately within a system. FSS licensees 
must provide FS licensees with reliability equal to the overall 
reliability of their system. For digital data systems, reliability is 
measured by the percent of time the bit error rate (BER) exceeds a 
desired value, and for analog or digital voice transmissions, it is 
measured by the percent of time that audio signal quality meets an 
established threshold. If an analog voice system is replaced with a 
digital voice system, only the resulting frequency response, harmonic 
distortion, signal-to-noise ratio and its reliability will be considered 
in determining comparable reliability.
    (3) Operating costs. Operating costs are the cost to operate and 
maintain the FS system. FSS licensees must compensate FS licensees for 
any increased recurring costs associated with the replacement facilities 
(e.g., additional rental payments, increased utility fees) for five 
years after relocation. FSS licensees may satisfy this obligation by 
making a lump-sum payment based on present value using current interest 
rates. Additionally, the maintenance costs to the FS licensee must be 
equivalent to the 18 GHz system in order for the replacement system to 
be considered comparable.
    (c) The FS 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. The 
FS licensee may take up to 12 months to make such adjustments and 
perform such testing.
    (d) If the FS licensee demonstrates to the Commission that the new 
facilities are not comparable to the former facilities, the Commission 
may require the FSS licensee to further modify or replace the FS 
licensee's equipment.

[65 FR 54173, Sept. 7, 2000, as amended at 66 FR 63516, Dec. 7, 2001]



Sec.  101.95  Sunset provisions for licensees in the 18.30-19.30 GHz band.

    (a) FSS licensees are not required to pay relocation costs after the 
relocation rules sunset (see Sec. Sec.  74.502(c), 74.602(g), and 
78.18(a)(4) of this chapter,

[[Page 673]]

and 101.147 (a) and (r)). Once the relocation rules sunset, an FSS 
licensee may require the incumbent to cease operations, provided that 
the FSS licensee intends to turn on a system within interference range 
of the incumbent, as determined by TIA Bulletin 10-F or any standard 
successor. FSS licensee notification to the affected FS licensee must be 
in writing and must provide the incumbent with no less than six months 
to vacate the spectrum. After the six-month notice period has expired, 
the FS licensee must turn its license back into the Commission, unless 
the parties have entered into an agreement which allows the FS licensee 
to continue to operate on a mutually agreed upon basis.
    (b) If the parties cannot agree on a schedule or an alternative 
arrangement, requests for extension will be accepted and reviewed on a 
case-by-case basis. The Commission will grant such extensions only if 
the incumbent can demonstrate that:
    (1) It cannot relocate within the six-month period (e.g., because no 
alternative spectrum or other reasonable option is available); and
    (2) The public interest would be harmed if the incumbent is forced 
to terminate operations (e.g., if public safety communications services 
would be disrupted).



Sec.  101.97  Future licensing in the 18.30-19.30 GHz band.

    (a) All major modifications and extensions to existing FS systems in 
the 18.3-18.58 band after November 19, 2002, or in the 18.58-19.30 band 
after June 8, 2000 (with the exception of certain low power operations 
authorized under Sec.  101.147(r)(10)) will be authorized on a secondary 
basis to FSS systems. All other modifications will render the modified 
FS license secondary to FSS operations, unless the incumbent 
affirmatively justifies primary status and the incumbent FS licensee 
establishes that the modification would not add to the relocation costs 
for FSS licensees. Incumbent FS licensees will maintain primary status 
for the following technical changes:
    (1) Decreases in power;
    (2) Minor changes (increases or decreases) in antenna height;
    (3) Minor location changes (up to two seconds);
    (4) Any data correction which does not involve a change in the 
location of an existing facility;
    (5) Reductions in authorized bandwidth;
    (6) Minor changes (increases or decreases) in structure height;
    (7) Changes (increases or decreases) in ground elevation that do not 
affect centerline height;
    (8) Minor equipment changes.
    (9) Changes in ownership or control.
    (b) The provisions of Sec.  101.83 are applicable, notwithstanding 
any other provisions of this section.

(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.
(2) Frequencies in this band are shared with stations in the fixed satellite service outside the contiguous United States. Applications for new
  permanent or temporary facilities in these bands will not be accepted for locations in the contiguous United States. Licensees, as of April 19, 2018,
  of existing permanent and temporary point-to-point Fixed Service links in the contiguous United States have until December 5, 2023, to self-relocate
  their point-to-point links out of the 3,700-4,200 MHz band. Such licensees may seek reimbursement of their reasonable costs based on the ``comparable
  facilities'' standard used for the transition of microwave links out of other bands, see Sec.   101.73(d) of this chapter (defining comparable
  facilities as facilities possessing certain characteristics in terms of throughput, reliability and operating costs) subject to the demonstration

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

[[Page 675]]

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 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)(1) Operations in the bands 31,000-31,075 MHz and 31,225-31,300 
MHz licensed prior to March 11, 1997, were licensed on an unprotected 
basis and are subject to harmful interference from similarly licensed 
operations in that band.
    (i) Operations licensed in the Local Mulitpoint Distribution Service 
and those operations licensed prior to March 11, 1997, except in the 
Local Television Transmission Service, operating in these bands are 
equally protected against harmful interference from each other.
    (ii) In the case of operations licensed prior to March 11, 1997, 
except in the Local Television Transmission Service, that are licensed 
on a point-to-radius basis, LMDS licensees shall be subject to the 
protection requirement established in this section in the case of 
existing links operated by such licensees, and in the case of links 
added by such licensees in the future in accordance with the terms of 
their point-to-radius licenses.
    (iii) An LMDS licensee may not initiate operations within the point-
to-radius area licensed to an operator (other than an operator in the 
Local Television Transmission Service) prior to March 11, 1997, even if 
such operator has not initiated operations to the fullest extent of the 
license. An LMDS licensee, however, may initiate operations at the 
border of such operator's license area without prior coordination if the 
LMDS licensee's operations would not cause harmful interference to the 
other operator's existing operations.
    (iv) An operator (other than an operator in the Local Television 
Transmission Service) licensed on a point-to-radius basis prior to March 
11, 1997, may add additional stations within its license area. Such 
operator shall coordinate with any affected LMDS licensee if its new 
operations might cause harmful interference to the existing operations 
of such LMDS licensee.
    (v) Operations licensed prior to March 11, 1997, on a point-to-point 
basis may not be extended or otherwise modified through the addition of 
point-to-point links. Such operations shall be limited to the use of 
frequency pairs licensed as of March 11, 1997. Operations licensed in 
the Local Television Transmission Service as of March 11, 1997, may 
continue to operate, but such operators may not expand existing 
operations nor initiate new operations.
    (2) Operations in the 31,075-31,225 MHz band licensed prior to March 
11, 1997, shall receive no protection against harmful interference from 
authorized operations in the Local Multipoint Distribution Service in 
that band.
    (3) Non-LMDS operations in the entire 31,000-31,300 MHz band 
licensed after March 11, 1997, based on applications refiled no later 
than June 26, 1998 are unprotected with respect to each other and 
subject to harmful interference from each other.
    (i) Such operations and any operations licensed prior to March 11, 
1997, in the band are unprotected with respect to each other and subject 
to harmful interference from each other.
    (ii) Such operations are licensed on a secondary basis to LMDS 
operations licensed in the band, may not cause interference to LMDS 
operations, and are not protected from interference from LMDS 
operations.
    (iii) Such operations licensed on a point-to-point basis may not be 
extended or otherwise modified through the addition of point-to-point 
links. Such operations licensed on a point-to-radius basis may add 
additional stations within the licensed area.
    (c) Frequency diversity transmission will not be authorized in these 
services

[[Page 676]]

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 a major 
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 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.

[[Page 677]]

    Frequencies and polarizations to be added, changed or deleted.
    Transmitting equipment type, its stability, actual output power, 
emission designator, and type of modulation(s) (loading). Notification 
shall indicate if modulations lower than the values listed in the table 
to Sec.  101.141(a)(3) of the Commission's rules will be used.
    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.
    For a system utilizing ATPC, maximum transmit power, coordinated 
transmit power, and nominal transmit power.

    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 Spatial 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 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

[[Page 678]]

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)(1) Coordination and information sharing between MVDDS and NGSO 
FSS licensees in the 12.2 GHz to 12.7 GHz band. Prior to the 
construction or addition of an MVDDS transmitting antenna in this 
frequency band, the MVDDS licensee shall provide notice of intent to 
construct the proposed antenna site to NGSO FSS licensees operating in 
the 12.2-12.7 GHz frequency band and maintain an Internet web site of 
all existing transmitting sites and transmitting antennas that are 
scheduled for operation within one year including the ``in service'' 
dates. In addition to the location of a proposed new transmitting 
antenna, MVDDS licensees shall provide to the NGSO FSS licensees a 
technical description of the operating characteristics of the proposed 
transmission facility. At a minimum, the following information must be 
included in each notification:
    (i) Name of MVDDS licensee;
    (ii) Geographic location (including NAD83 coordinates) of proposed 
MVDDS transmitting antenna;
    (iii) Maximum EIRP per 24 MHz;
    (iv) Height above average terrain of the transmitting antenna;
    (v) Type of antenna to be utilized;
    (vi) Main beam azimuth and altitude orientation for the proposed 
transmitting antenna;
    (vii) Theoretically modeled antenna radiation pattern;
    (viii) Type(s) of emissions, and;
    (ix) Description of the proposed service area.
    (2) If the proposed MVDDS antenna site does not meet the minimum 
spacing requirements on the date of original notification or on 
subsequent annual anniversary dates of non-operation as set forth in 
Sec.  101.129, then the MVDDS licensee shall not construct the proposed 
transmission facility unless all NGSO FSS licensees having active 
subscribers within the minimum separation distance agree to a shorter 
spacing. Nothing in this section shall

[[Page 679]]

preclude MVDDS and NGSO FSS licensees from agreeing to accept the siting 
of new MVDDS transmitting antennas that do no meet the minimum distance 
set forth in Sec.  101.129. Incumbent point-to-point licensees' (those 
not licensed as MVDDS) facilities are to be operated in the band 12,200-
12,700 MHz following the procedures, technical standards, and 
requirements of Sec.  101.105 in order to protect stations providing 
Direct Broadcast Satellite Service.
    (g) Licensees operating in Basic Trading Areas authorized in the 
Local Multipoint Distribution Service. (1) When the transmitting 
facilities in a Basic Trading Area (BTA) are to be operated in the bands 
29,100-29,250 MHz and 31,000-31,300 MHz and the facilities are located 
within 20 kilometers of the boundaries of a BTA, each licensee must 
complete the frequency coordination process of paragraph (d)(2) of this 
section with respect to neighboring BTA licensees that may be affected 
by its operations prior to initiating service. In addition, all licensed 
transmitting facilities operating in the bands 31,000-31,075 MHz and 
31,225-31,300 MHz and located within 20 kilometers of neighboring 
facilities must complete the frequency coordination process of paragraph 
(d)(2) of this section with respect to such authorized operations before 
initiating service.
    (2) 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, either 
electronically or in writing, within the 30-day notification period. 
Every reasonable effort should be made by all licensees to eliminate all 
problems and conflicts. If no response to notification is received 
within 30 days, the licensee will be deemed to have made reasonable 
efforts to coordinate and commence operation without a response. The 
beginning of the 30-day period is determined pursuant to paragraph 
(d)(2)(v) of this section.
    (h) Special requirements for operations in the band 29,100-29,250 
MHz. (1)(i) Local Multipoint Distribution Service (LMDS) receive 
stations operating on frequencies in the 29,100-29,250 MHz band within a 
radius of 75 nautical miles of the geographic coordinates provided by a 
non-GSO-MSS licensee pursuant to Sec.  101.113(c)(2) or (c)(3)(i) (the 
``feeder link earth station complex protection zone'') shall accept any 
interference caused to them by such earth station complexes and shall 
not claim protection from such earth station complexes.
    (ii) LMDS licensees operating on frequencies in the 29,100-29,250 
MHz band outside a feeder link earth station complex protection zone 
shall cooperate fully and make reasonable efforts to resolve technical 
problems with the non-GSO MSS licensee to the extent that transmissions 
from the non-GSO MSS operator's feeder link earth station complex 
interfere with an LMDS receive station.
    (2) No more than 15 days after the release of a public notice 
announcing the commencement of LMDS auctions, feeder link earth station 
complexes to be licensed pursuant to Sec.  25.257 of this chapter shall 
be specified by a set of geographic coordinates in accordance with the 
following requirements: no feeder link earth station complex may be 
located in the top eight (8) metropolitan statistical areas (MSAs), 
ranked by population, as defined by the Office of Management and Budget 
as of June 1993, using estimated populations as of December 1992; two 
(2) complexes may be located in MSAs 9 through 25, one of which must be 
Phoenix, AZ (for a complex at Chandler, AZ); two (2) complexes may be 
located in MSAs 26 to 50; three (3) complexes may be located in MSAs 51 
to 100, one of which must be Honolulu, Hawaii (for a complex at Waimea); 
and the three (3) remaining complexes must be located at least 75 
nautical miles from the borders of the 100 largest MSAs or in any MSA 
not included in the 100 largest MSAs. Any location allotted for one 
range of MSAs may be taken from an MSA below that range.
    (3)(i) Any non-GSO MSS licensee may at any time specify sets of 
geographic coordinates for feeder link earth station complexes with each 
earth station contained therein to be located at least 75 nautical miles 
from the border of the 100 largest MSAs.

[[Page 680]]

    (ii) For purposes of paragraph (h)(3)(i) of this section, non-GSO 
MSS feeder link earth station complexes shall be entitled to 
accommodation only if the affected non-GSO MSS licensee preapplies to 
the Commission for a feeder link earth station complex or certifies to 
the Commission within sixty days of receiving a copy of an LMDS 
application that it intends to file an application for a feeder link 
earth station complex within six months of the date of receipt of the 
LMDS application.
    (iii) If said non-GSO MSS licensee application is filed later than 
six months after certification of the Commission, the LMDS and non-GSO 
MSS entities shall still cooperate fully and make reasonable efforts to 
resolve technical problems, but the LMDS licensee shall not be obligated 
to re-engineer its proposal or make changes to its system.
    (4) LMDS licensees or applicants proposing to operate hub stations 
on frequencies in the 29,100-29,250 MHz band at locations outside of the 
100 largest MSAs or within a distance of 150 nautical miles from a set 
of geographic coordinates specified under paragraphs (h)(2) or (h)(3)(i) 
of this section shall serve copies of their applications on all non-GSO 
MSS applicants, permittees or licensees meeting the criteria specified 
in Sec.  25.257(a). Non-GSO MSS licensees or applicants shall serve 
copies of their feeder link earth station applications, after the LMDS 
auction, on any LMDS applicant or licensee within a distance of 150 
nautical miles from the geographic coordinates that it specified under 
Sec.  101.113(c)(2) or (c)(3)(i). Any necessary coordination shall 
commence upon notification by the party receiving an application to the 
party who filed the application. The results of any such coordination 
shall be reported to the Commission within sixty days. The non-GSO MSS 
earth station licensee shall also provide all such LMDS licensees with a 
copy of its channel plan.

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.
    (4) 12.2-12.7 GHz band. (i) To accommodate co-primary NGSO FSS earth 
stations in the 12.2-12.7 GHz band, the PFD of an MVDDS transmitting 
system must not exceed -135 dBW/m\2\ in any 4 kHz band at a reference 
point at the surface of the earth at a distance greater than 3 
kilometers from the MVDDS transmitting antenna.
    (ii) To accommodate co-primary Direct Broadcast Satellite Service 
earth stations, an MVDDS transmitting system must not exceed the EPFD 
levels specified in paragraph (a)(4)(ii)(B) of

[[Page 681]]

this section at any DBS subscriber location in accordance with the 
procedures listed in Sec.  101.1440 of this part.
    (A) Definition of equivalent power flux density: The equivalent 
power flux density (EPFD) is the power flux density produced at a direct 
broadcast service (DBS) receive earth station, taking into account 
shielding effects and the off-axis discrimination of the receiving 
antenna assumed to be pointing at the appropriate DBS satellite(s) from 
the transmitting antenna of a multichannel video distribution and data 
service (MVDDS) transmit station. The EPFD in dBW/m\2\ in the reference 
bandwidth is calculated using the following formula:
[GRAPHIC] [TIFF OMITTED] TR07JN04.000

Where:

Pout = Total output power of the MVDDS transmitter (watts) 
          into antenna
Gm ([thetas]m,[phis]m = Gain of the MVDDS antenna 
          in the direction of the DBS earth station
Ge ([thetas]e,[phis]e = Gain of the 
          earth station in the direction of the MVDDS antenna
I = Interference scaling factor for the earth station (1 dB for MVDDS 
          transmitters employing the modulation discussed in Section 
          3.1.5 of the MITRE Report (i.e., a QPSK modulated signal 
          passed through a square-root raised cosine filter). For other 
          modulation and filtering schemes, the interference scaling 
          factor can be measured using the procedures described in 
          Appendix A of the MITRE Report available at http://
          www.fcc.gov/oet/ info/mitrereport/ mitrereport_4_01.pdf).
Ge, max = Maximum gain of the DBS earth station
d = the distance between the MVDDS transmitting antenna and the DBS 
          earth station (meters)

    (B) Regional equivalent power flux density levels:
    (1) -168.4 dBW/m\2\/4kHz in the Eastern region consisting of the 
District of Columbia and the following states: Maine, New Hampshire, 
Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, 
Pennsylvania, Delaware, Maryland, Virginia, West Virginia, Kentucky, 
Tennessee, North Carolina, South Carolina, Georgia, Alabama, 
Mississippi, Louisiana, and Florida;
    (2) -169.8 dBW/m\2\/4kHz in the Midwestern region consisting of the 
following states: Ohio, Michigan, Indiana, Wisconsin, Illinois, 
Minnesota, Iowa, Missouri, Arkansas, South Dakota, Nebraska, Kansas, 
Oklahoma, and Texas;
    (3) -171.0 dBW/m\2\/4kHz in the Southwestern region consisting of 
the following states: Wyoming, Colorado, New Mexico, Utah, Arizona, 
Nevada, and California (south of 37[deg] North Latitude);
    (4) -172.1 dBW/m\2\/4kHz in the Northwestern region consisting of 
the following states: Washington, Oregon, California (north of 37[deg] 
North Latitude), Idaho, Montana, North Dakota, Alaska, and Hawaii.
    (iii) Except for public safety entities, harmful interference 
protection from MVDDS stations to incumbent point-to-point 12 GHz fixed 
stations is not required. Incumbent point-to-point private operational 
fixed 12 GHz stations, except for public safety entities, are required 
to protect MVDDS stations under the process described in Sec.  
101.103(d) of this part.
    (5) 71,000-76,000 MHz; 81,000-86,000 MHz. In these bands the 
following interference criteria shall apply:
    (i) For receivers employing digital modulation: based upon 
manufacturer data and following TSB 10-F or other generally acceptable 
good engineering practice, for each potential case of interference a 
threshold-to-interference ratio (T/I) shall be determined that would 
cause 1.0 dB of degradation to the static threshold of the protected 
receiver. For the range of carrier power levels (C) between the clear-
air (unfaded) value and the fully-faded static threshold value, in no 
case shall interference cause C/I to be less than the T/I so determined 
unless it can be

[[Page 682]]

shown that the availability of the affected receiver would still be 
acceptable despite the interference.
    (ii) For receivers employing analog modulation: manufacturer data or 
industry criteria will specify a baseband signal-to-noise requirement 
(S/N) of the receiver that will result in acceptable signal quality for 
continuous operation. Following TSB 10-F or other generally acceptable 
good engineering practice, for each potential case of interference a C/I 
objective shall be calculated to ensure that this S/N will not be 
degraded by more than 1.0 dB. For the range of carrier power levels (C) 
between the clear-air (unfaded) value and the fully-faded threshold 
value, in no case shall interference cause the C/I to be less than the 
objective so determined unless it can be shown that the signal quality 
and availability of the affected receiver would still be acceptable 
despite the interference.
    (6) 92,000-94,000 MHz; 94,100-95,000 MHz. In these bands prior links 
shall be protected to a threshold-to-interference ratio (T/I) level of 
1.0 dB of degradation to the static threshold of the protected receiver. 
Any new link shall not decrease a previous link's desired-to-undesired 
(D/U) signal ratio below a minimum of 36 dB, unless the earlier link's 
licensee agrees to accept a lower D/U.
    (7) All stations operating under this part must protect the radio 
quiet zones as required by Sec.  1.924 of this chapter. Stations 
authorized by competitive bidding are cautioned that they must receive 
the appropriate approvals directly from the relevant quiet zone entity 
prior to operating.
    (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 
applicant's 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 side band 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 952-960 MHz band where it must be 75dB, and 
in the 71,000-76,000 MHz and 81,000-86,000 MHz bands where the criteria 
in paragraph (a)(5) of this section applies, and in the 92,000-94,000 
MHz and 94,100-95,000 MHz bands, where the criteria in paragraph (a)(6) 
of this section applies; 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, except in the 
71,000-76,000 MHz and 81,000-86,000 MHz bands where the criteria in 
paragraph (a)(5) of this section applies, and in the 92,000-94,000 MHz 
and 94,100-95,000 MHz bands, where the criteria in paragraph (a)(6) of 
this section applies.
    (3) Applicants for frequencies listed in Sec.  101.147(b)(1) through 
(4) must make the following showings that protection

[[Page 683]]

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 site-based multiple address stations in the 928-929/952-960 
MHz and the 932-932.5/941-941.5 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 paragraph (c)(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) In cases where the geographic separation standard in paragraph 
(c)(3)(i) of this section is 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.
    (iii) MAS EA licensees shall provide protection in accordance with 
Sec.  101.1333.
    (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 956.25-956.45 MHz bands may 
be assigned for use by mobile master stations on a primary basis. 
Multiple address frequencies in the 941.0-941.5 MHz bands that are 
licensed on a site-by-site basis and the 952 MHz bands may be assigned 
for use by primary mobile master stations on a case-by-case basis if the 
956.25-956.45 MHz frequencies are unavailable. Multiple address mobile 
(master and remote) operation is permitted on frequencies licensed by 
geographic area subject to the interference protection criteria set 
forth in Sec.  101.1333, i.e., adjacent channel site-based licensees and 
co-channel operations in adjacent EAs. Mobile operation in the 959.85-
960 MHz band is not permitted.
    (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 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:

------------------------------------------------------------------------
                         AAT (meters)                           EIRP dBm

Above 300....................................................       + 38
251 to 300...................................................         41
201 to 250...................................................         43
151 to 200...................................................         49
101 to 150...................................................         55
100 and below................................................         85
------------------------------------------------------------------------

    (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

[[Page 684]]

all other licensed and previously applied for co-channel and adjacent 
channel stations 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, for an incumbent non-MVDDS station or 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:
    (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

------------------------------------------------------------------------
\1\Applicable only to common carrier LTTS stations. Tolerance for 2450-
  2500 MHz is 0.005%. 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% in the frequency
  range 2,200 to 10,500 MHz and .05% 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. Beginning March 1, 2005, new LTTS operators will not
  be licensed and existing LTTS licensees will not be renewed in the
  11.7-12.2 GHz band.
\2\ See subpart G of this part for the stability requirements for
  transmitters used in the Digital Electronic Message Service.
\3\ 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 current tolerance be met.
\4\ Applicable to private operational fixed point-to-point microwave and
  stations providing MVDDS.
\5\ 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%.
\6\ For stations authorized prior to March 11, 1997, transmitter
  tolerance shall not exceed 0.03%.
\7\ The frequency tolerance for stations authorized on or before April
  1, 2005 is 0.03%. Existing licensees and pending applicants on that
  date may continue to operate after that date with a frequency
  tolerance of 0.03%, provided that it does not cause harmful
  interference to the operation of any other licensee. For analog
  systems, if the channel bandwidth is greater than 30 MHz up to 50 MHz,
  the frequency tolerance standard will be 0.03%; if the channel
  bandwidth is 30 MHz or less, then the frequency tolerance standard
  will be 0.003%. This analog standard is conditional provided that
  harmful interference is not caused to digital stations operating
  within the 0.001% tolerance standards. If harmful interference is
  caused to stations operating with the more stringent standard, the
  onus shall be on the operators with the less stringent parameters to
  develop an engineering solution to the problem. For exceptions, see
  Sec.   101.147 and Sec.   101.507.
\8\ Equipment authorized to be operated in the 71,000-76,000 MHz, 81,000-
  86,000 MHz, 92,000-94,000 MHz and 94,100-95,000 MHz bands is exempt
  from the frequency tolerance requirement noted in the table of
  paragraph (a) of this section.

    (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

[[Page 686]]

frequency band, the Commission reserves the right to issue a license for 
less than the maximum bandwidth if it appears that a lesser bandwidth 
would be sufficient to support an applicant's intended communications.

\1\ The maximum bandwidth that will be authorized for each particular
  frequency in this band is detailed in the appropriate frequency table
  in Sec.   101.147. If contiguous channels are aggregated in the 928-
  928.85/952-952.85/956.25-956.45 MHz, the 928.85-929/959.85-960 MHz, or
  the 932-932.5/941-941.5 MHz bands, then the bandwidth may exceed that
  which is listed in the table.
\2\ 1250 KHz, 1875 KHz, or 2500 KHz on a case-by-case basis.
\3\ To be specified in authorization. For the band 92 to 95 GHz, maximum
  bandwidth is licensed in one segment of 2 GHz from 92-94 GHz and one
  0.9 GHz segment from 94.1 to 95 GHz, or the total of the loaded band
  if smaller than the assigned bandwidth.
\4\ For exceptions, see Sec.   101.147(s).
\5\ A 12.5 kHz bandwidth applies only to frequencies listed in Sec.
  101.147(b)(1) through (4).
\6\ For frequencies listed in Sec.   101.147(b)(1) through (4),
  consideration will be given on a case-by-case basis to authorizing
  bandwidths up to 50 kHz.
\7\ For channel block assignments in the 24,250-25,250 MHz band, the
  authorized bandwidth is equivalent to an unpaired channel block
  assignment or to either half of a symmetrical paired channel block
  assignment. When adjacent channels are aggregated, equipment is
  permitted to operate over the full channel block aggregation without
  restriction.
Note to footnote 7: Unwanted emissions shall be suppressed at the
  aggregate channel block edges based on the same roll-off rate as is
  specified for a single channel block in Sec.   101.111(a)(1) or in
  Sec.   101.111(a)(2)(ii) and (iii) as appropriate.
\8\ For incumbent private operational fixed point-to-point stations in
  this band (those not licensed as MVDDS), the maximum bandwidth shall
  be 20 MHz.

Sec.  101.111  Emission limitations.

    (a) The mean power of emissions must be attenuated below the mean 
output power of the transmitter in accordance with the following 
schedule:
    (1) When using transmissions other than those employing digital 
modulation techniques:
    (i) On any frequency removed from the assigned frequency by more 
than 50 percent up to and including 100 percent of the authorized 
bandwidth: At least 25 decibels;
    (ii) On any frequency removed from the assigned frequency by more 
than 100 percent up to and including 250 percent of the authorized 
bandwidth: At least 35 decibels;
    (iii) On any frequency removed from the assigned frequency by more 
than 250 percent of the authorized bandwidth: At least 43 + 10 
Log10 (mean output power in watts) decibels, or 80 decibels, 
whichever is the lesser attenuation.
    (2) When using transmissions employing digital modulation techniques 
(see Sec.  101.141(b)) in situations not covered in this section:
    (i) For operating frequencies below 15 GHz, in any 4 KHz band, the 
center frequency of which is removed from the assigned frequency by more 
than 50 percent up to and including 250 percent of the authorized 
bandwidth: As specified by the following equation but in no event less 
than 50 decibels:

A = 35 + 0.8(P -50) + 10 Log10 B. (Attenuation greater than 80 decibels 
or to an absolute power of less than -13 dBm/1MHz is not required.) 
where:


[[Page 687]]


A = Attenuation (in decibels) below the mean output power level.
P = Percent removed from the center frequency of the transmitter 
          bandwidth.
B = Authorized bandwidth in MHz.

    Note: MVDDS operations in the 12.2-12.7 GHz band shall use 24 
megahertz for the value of B in the emission mask equation set forth in 
this section. The emission mask limitation shall only apply at the 12.2-
12.7 GHz band edges and does not restrict MVDDS channelization bandwidth 
within the band.

    (ii) For operating frequencies above 15 GHz, in any 1 MHz band, the 
center frequency of which is removed from the assigned frequency by more 
than 50 percent up to and including 250 percent of the authorized 
bandwidth: As specified by the following equation but in no event less 
than 11 decibels:

A = 11 + 0.4(P-50) + 10 Log10 B. (Attenuation greater than 56 
decibels or to an absolute power of less than -13 dBm/1MHz is not 
required.)

    (iii) In any 1 MHz band, the center frequency of which is removed 
from the assigned frequency by more than 250 percent of the authorized 
bandwidth: At least 43 + 10 Log10 (the mean output power in 
watts) decibels, or 80 decibels, whichever is the lesser attenuation. 
The authorized bandwidth includes the nominal radio frequency bandwidth 
of an individual transmitter/modulator in block-assigned bands. 
Equipment licensed prior to April 1, 2005 shall only be required to meet 
this standard in any 4 kHz band.
    (iv) The emission mask for LMDS and the 24 GHz Service shall use the 
equation in paragraph (a)(2)(ii) of this section and apply it only to 
the band edge of each block of spectrum, but not to subchannels 
established by licensees. The value of P in the equation is the 
percentage removed from the carrier frequency and assumes that the 
carrier frequency is the center of the actual bandwidth used. The 
emission mask can be satisfied by locating a carrier of the subchannel 
sufficiently far from the channel edges so that the emission levels of 
the mask are satisfied. The LMDS or 24 GHz emission mask shall use a 
value B (bandwidth) of 40 MHz, for all cases even in the case where a 
narrower subchannel is used (for instance the actual bandwidth is 10 
MHz) and the mean output power used in the calculation is the sum of the 
output power of a fully populated channel. For block assigned channels, 
the out-of-band emission limits apply only outside the assigned band of 
operation and not within the band.
    (v) The emission mask for the 71-76 GHz, 81-86 GHz, 92-94 GHz, and 
94.1-95 GHz bands used in the equation in paragraph (a)(2)(ii) of this 
section applies only to the edge of each channel, but not to sub-
channels established by licensees. The value of P in the equation is for 
the percentage removed from the carrier frequency and assumes that the 
carrier frequency is the center of the actual bandwidth used. The value 
of B will always be 500 MHz. In the case where a narrower sub-channel is 
used within the assigned bandwidth, such sub-carrier will be located 
sufficiently far from the channel edges to satisfy the emission levels 
of the mask. The mean output power used in the calculation is the sum of 
the output power of a fully populated channel.
    (3) For Digital Termination System channels used in the Digital 
Electronic Message Service (DEMS) operating in the 10,550-10,680 MHz 
band:
    (i) In any 4 KHz band, the center frequency of which is removed from 
the edge of the DEMS channel by up to and including 1.125 times the DEMS 
subchannel bandwidth: As specified by the following equation may in no 
event be less than 50 + 10 log10 N decibels:

A = 50 + 0.0333(F - 0.5B) + 10 log10 N decibels

Where:

A = Attenuation (in decibels) below means output power level contained 
          within the DEMS channel for a given polarization.
B = Bandwidth of DEMS channel (in KHz).
F = Absolute value of the difference between the center frequency of the 
          4 KHz band measured and the center frequency of the DEMS 
          channel (in KHz).
N = Number of active subchannels of the given polarization within the 
          DEMS channel.

    (ii) In any 4 KHz band within the authorized DEMS band the center 
frequency of which is removed from the center frequency of the DEMS 
channel by more than the sum of 50% of the DEMS channel bandwidth plus 
1.125 times the subchannel bandwidth: As

[[Page 688]]

specified by the following equation but in no event less than 80 
decibels:

A = 80 + 10 log10 N decibels

    (iii) In any 4 KHz band the center frequency of which is outside the 
authorized DEMS band: At least 43 + 10 log10 (mean output 
power in watts) decibels.
    (4) For DEMS channels in the 17,700-19,700 MHz band:
    (i) In any 4 KHz band, the center frequency of which is removed from 
the frequency of the center of the DEMS channel by more than 50 percent 
of the DEMS channel bandwidth up to and including 50 percent plus 500 
KHz: As specified by the following equation but in no event be less than 
50 + 10 log10 N decibels:

A = 50 + 0.06(F -0.5B) + 10 log10 N decibels

Where:

A = Attenuation (in decibels) below means output power level contained 
          within the DEMS channel for a given polarization.
B = Bandwidth of DEMS channel (in KHz).
F = Absolute value of the difference between the center frequency of the 
          4 KHz band measured and the center frequency of the DEMS 
          channel (in KHz).
N = Number of active subchannels of the given polarization within the 
          DEMS channel.

    (ii) In any 4 KHz band within the authorized DEMS band, the center 
frequency of which is removed from the center frequency of the DEMS 
channel by more than the sum of 50 percent of the channel bandwidth plus 
500 KHz: As specified by the following equation but in no event less 
than 80 decibels:

A = 80 + 10 log10 N decibels

    (iii) In any 4 KHz band the center frequency of which is outside the 
authorized Digital Message Service band: At least 43 + 10 
log10 (mean output power in watts) decibels.
    (5) When using transmissions employing digital modulation techniques 
on the 900 MHz multiple address frequencies with a 12.5 KHz bandwidth, 
the power of any emission must be attenuated below the unmodulated 
carrier power of the transmitter (P) in accordance with the following 
schedule:
    (i) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in KHz) of more than 2.5 KHz 
up to and including 6.25 KHz: At least 53 log10 (fd/2.5) 
decibels;
    (ii) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in KHz) of more than 6.25 KHz 
up to and including 9.5 KHz: At least 103 log10 (fd/3.9) 
decibels;
    (iii) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in KHz) of more than 9.5 KHz

decibels; and
    (iv) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency greater than 15 KHz: At least 50 
plus 10 log10(P) or 70 decibels, whichever is the lesser 
attenuation.
    (6) When using transmissions employing digital modulation techniques 
on the 900 MHz multiple address frequencies with a bandwidth greater 
than 12.5 KHz, the power of any emission must be attenuated below the 
unmodulated carrier power of the transmitter (P) in accordance with the 
following schedule:
    (i) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in KHz) of more than 5 KHz up 
to and including 10 KHz: At least 83 log10 (fd/5) decibels;
    (ii) On any frequency removed from the center of the authorized 
bandwidth by a displacement frequency (fd in KHz) of more than 10 KHz up 
to and including 250 percent of the authorized bandwidth: At least 116 
log10 (fd/6.1) decibels or 50 plus 10 log10 (P) or 
70 decibels, whichever is the lesser attenuation; and
    (iii) On any frequency removed from the center of the authorized 
bandwidth by more that 250 percent of the authorized bandwidth: At least 
43 plus 10 log10 (output power in watts) decibels or 80 
decibels, whichever is the lesser attenuation.
    (b) When an emission outside of the authorized bandwidth causes 
harmful interference, the Commission may, at its discretion, require 
greater attenuation than specified in paragraph (a) of this section.

[[Page 689]]

    (c) The emission of an unmodulated carrier is prohibited except for 
test purposes as required for proper station and system maintenance.
    (d) Interference to passive sensors. These limitations are necessary 
to minimize the probability of harmful interference to reception in the 
10.6-10.68 GHz and 31-31.3 GHz bands onboard space stations in the Earth 
exploration-satellite service (passive).
    (1) 10.6-10.68 GHz. (i) Fixed stations are restricted to point-to-
point operations, with each station supplying not more than -3 dBW of 
transmitter power to the antenna, producing not more than 40 dBW of 
EIRP, and radiating at an antenna main beam elevation angle of 20[deg] 
or less. Licensees holding a valid authorization on August 6, 2015 to 
operate in this band may continue to operate as authorized, subject to 
proper license renewal. Licensees are urged to:
    (A) Limit the maximum transmitter power supplied to the antenna to -
15 dBW; and
    (B) Employ automatic transmitter power control (ATPC).
    (ii) The maximum transmitter power supplied to the antenna of 
stations using ATPC may be increased by a value corresponding to the 
ATPC range, up to a maximum of -3 dBW.
    (2) 31-31.3 GHz. For fixed stations authorized after August 6, 2018, 
the unwanted emissions power in any 100 MHz of the 31.3-31.5 GHz band 
shall be limited to -38 dBW (-38 dBW/100 MHz), as measured at the input 
to the antenna.

Sec.  101.113  Transmitter power limitations.

    (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:

  units that are part of a multiple address central station projection
  system are authorized a maximum of 2 watts.
\3\ When an omnidirectional antenna is authorized in the 2150-2160 MHz
  band, the maximum power shall be 60 dBm.
\4\ Also see Sec.   101.145.

[[Page 690]]

 
\5\ The output power of a DEMS System nodal transmitter shall not exceed
  0.5 watt per 250 kHz. The output power of a DEMS System user
  transmitter shall not exceed 0.04 watt per 250 kHz. The transmitter
  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. Frequencies from
  10,600-10,680 MHz are subject to footnote US265 in the Table of
  Frequency Allocations in Sec.   2.106 of the Commission's Rules.
  Stations authorized prior to April 1, 2003 to exceed the 40 dBW limit
  may continue to operate at their authorized output power level
  indefinitely, provided that neither end point of the relevant link is
  relocated.
\6\ Maximum power delivered to the antenna shall not exceed -3 dBw.
\7\ See Sec.   101.113(c).

specified in the instrument of station authorization.
    (c)(1) Transmitter power limitations. Point-to-point stations in the 
29.1-29.25 GHz band for the LMDS backbone between LMDS hubs shall be 
limited to a maximum allowable e.i.r.p. density per carrier of 23 dBW/
MHz in any one megahertz in clear air, and may exceed this limit by

the extent that the link is impaired.
    (2) Hub transmitter EIRP spectral area, density limit. LMDS 
applicants shall demonstrate that, under clear air operating conditions, 
the maximum aggregate of LMDS transmitting hub stations in a Basic 
Trading Area in the 29.1-29.25 GHz band will not transmit a co-frequency 
hub-to-subscriber e.i.r.p. spectral area density in any azimuthal 
direction in excess of X dBW/(MHz-km \2\) when averaged over any 4.375

that, under clear air operating conditions, the maximum aggregate of 
LMDS transmitting hub stations in a Basic Trading Area in the 29.1-29.25

spectral area density in any azimuthal direction in excess of X dBW/
(MHz-km\2\) when averaged over any 4.375 MHz band where X is defined in 
Table 2. Individual hub stations may exceed their clear air e.i.r.p.s by 
employment of adaptive power control in cases where link propagation 
attenuation exceeds the clear air value and only to the extent that the

          is the hub e.i.r.p. area density at the horizon used in 
          Section 101.113c(2). The nominal antenna pattern will be used 
          for elevation angles between 0[deg] and 8[deg], and average 
          levels will be used for angles beyond 8[deg], where average 
          levels will be calculated by sampling the antenna patterns in 
          each 1[deg] interval between 8[deg] and 9015, dividing by 83.

    (ii) LMDS system licensees in two or more BTAs may individually or 
collectively deviate from the spectral area density computed above by 
averaging the power over any 200 km by 400 km area, provided that the 
aggregate interference to the satellite receiver is no greater than if 
the spectral area density were as specified in Table 1. A showing to the 
Commission comparing both methods of computation is required and copies 
shall be served on any affected non-GSO MSS providers.
    (4) Power reduction techniques. LMDS hub transmitters shall employ 
methods to reduce average power levels received by non-geostationary 
mobile satellite receivers, to the extent necessary to comply with 
paragraphs (c)(1) and (c)(2) of this section, by employing the methods 
set forth below:
    (i) Alternate polarizations. LMDS hub transmitters in the LMDS 
service area may employ both vertical and horizontal linear 
polarizations such that 50 percent (plus or minus 10 percent) of the hub 
transmitters shall employ vertical polarization and 50 percent (plus or 
minus 10 percent) shall employ horizontal polarization.
    (ii) Frequency interleaving. LMDS hub transmitters in the LMDS 
service area may employ frequency interleaving such that 50 percent 
(plus or minus 10 percent) of the hub transmitters shall employ channel 
center frequencies which are different by one-half the channel bandwidth 
of the other 50 percent (plus or minus 10 percent) of the hub 
transmitters.
    (iii) Alternative methods. As alternatives to paragraphs (c)(4)(i) 
and (c)(4)(ii) of this section, LMDS operators may employ such other 
methods as may be shown to achieve equivalent reductions in average 
power density received by non-GSO MSS satellite receivers.

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) 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 subject 
to frequency congestion, antennas meeting performance Standard B may be 
used, subject to the requirements set forth in paragraph (d) of this 
section. For frequencies with a Standard B1 and a Standard B2, in order 
to comply with Standard B an antenna must fully meet either Standard B1 
or Standard B2. Licensees shall comply

with the antenna standards table shown in this paragraph in the 
following manner:
    (1) With either the maximum beamwidth to 3 dB points requirement or 
with the minimum antenna gain requirement; and
    (2) With the minimum radiation suppression to angle requirement.

--------------------------------------------------------------------------------------------------------------------------------------------------------
\1\ If a licensee chooses to show compliance using maximum beamwidth to 3 dB points, the beamwidth limit shall apply in both the azimuth and the
  elevation planes.
\2\ Except for Multiple Address System frequencies listed in Sec.  Sec.   101.147(b)(1) through (b)(4), where omnidirectional antennas may be used.
\3\ 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

[[Page 693]]

 
(ii) The minimum front-to-back ratio must be at least 20 dB.
\4\ Omnidirectional antennas may be authorized in the band 2150-2160 MHz.
\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\ For stations authorized or pending on April 1, 2003, the minimum radiation suppression for Category B is 35dB in the 10,550-10,680 MHz band and 36
  dB in the 21,200-23,600 MHz band for discrimination angles from 100[deg] to 180[deg].
\8\ These antenna standards apply only to DEMS User Stations licensed, in operation, or applied for prior to July 15, 1993.
\9\ 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), and
  except for antennas in the MVDDS service in the band 12.2-12.7 GHz.
\10\ 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. Stations authorized to operate in the
  24,250-25,250 MHz band do not have to meet these standards, however, the Commission may require the use of higher performance antennas where
  interference problems can be resolved by the use of such antennas.
\11\ Except as provided in Sec.   101.147(s).
\12\ The minimum front-to-back ratio shall be 38 dBi.
\13\ Mobile, except aeronautical mobile, stations need not comply with these standards.
\14\ Antenna gain less than 50 dBi (but greater than or equal to 43 dBi) is permitted only with a proportional reduction in maximum authorized EIRP in a
  ratio of 2 dB of power per 1 dB of gain, so that the maximum allowable EIRP (in dBW) for antennas of less than 50 dBi gain becomes + 55-2(50-G), where
  G is the antenna gain in dBi. In addition, antennas in these bands must meet two additional standards for minimum radiation suppression: At angles
  between 1.2 and 5 degrees from the centerline of the main beam, co-polar discrimination must be G-28, where G is the antenna gain in dBi; and at
  angles of less than 5 degrees from the centerline of main beam, cross-polar discrimination must be at least 25 dB.

    (c) 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 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.
    (d) 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.
    (e) 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.
    (f) In the 10,700-11,700 MHz band, a fixed station may employ 
transmitting and receiving antennas meeting performance standard B in 
any area. If a Fixed Service or Fixed Satellite Service licensee or 
applicant makes a showing that it is likely to receive interference from 
such fixed station and that such interference would not exist if the 
fixed station used an antenna meeting performance standard A, the fixed 
station licensee must modify its use. Specifically, the fixed station 
licensee must either substitute an antenna meeting performance standard 
A or operate its system with an EIRP reduced so as not to radiate, in 
the direction of the other licensee, an EIRP in excess of that which 
would be radiated by a station using a Category A antenna and operating 
with the maximum EIRP allowed by the rules. A licensee or prior 
applicant using an antenna that does not meet performance Standard A may 
object to a prior coordination notice based on interference only if such 
interference would be predicted to exist if the licensee or prior 
applicant used an antenna meeting performance standard A.
    (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 that may be employed. However, in the event 
interference in excess of permissible levels is caused to the operation 
of other stations as a result of employing other than linear 
polarization, the Commission may order a licensee to change its system 
polarization to mitigate the interference. No change in polarization may 
be made without prior authorization from the Commission. Unless 
otherwise allowed, only linear polarization (horizontal and vertical) 
shall be used. For LMDS systems, unless otherwise authorized, system 
operators are permitted to use any polarization within its service area, 
but only vertical and/or horizontal polarization for antennas located 
within 20 kilometers of the outermost edge of their service area.

[68 FR 4957, Jan. 31, 2003]



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.  101.125  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.  101.129  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 an experimental license 
under part 5 of this chapter. 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) In the 12.2-12.7 GHz band, licensees must not locate MVDDS 
transmitting antennas within 10 km of any qualifying NGSO FSS receiver 
unless mutual agreement is obtained between the MVDDS and NGSO FSS 
licensees. Such agreements must be retained by the licensees and made 
available for inspection by interested parties upon request.
    (1) A qualifying NGSO FSS receiver, for the purposes of this 
section, is deemed to be one that is in regular use by an NGSO FSS 
subscriber for normal reception purposes in the 12.2-12.7 GHz band and 
not one for monitoring or

[[Page 695]]

testing purposes. In addition, qualifying receivers must either be in 
operation on the date or already be under construction and then 
operating within thirty days of the date that the MVDDS licensee 
notifies the NGSO FSS licensee of its intent to construct a new MVDDS 
transmitting antenna at a specified location.
    (2) Except as provided in paragraph (b)(3) of this section, the 10 
kilometer spacing requirement for each MVDDS transmitting antenna site 
shall not apply with respect to NGSO FSS receivers that might be 
installed or become operational (except for those under construction and 
operating within thirty days as specified in paragraph (b)(1) of this 
section) subsequent to the original date that the MVDDS licensee 
provided notice of its intention to construct a given transmission 
facility.
    (3) In the event that a proposed MVDDS transmitting antenna for 
which notice has been duly given to the NGSO FSS licensees has not been 
placed in normal operation within one calendar year of the date of 
notice, then the MVDDS licensee loses the benefit of the original 
notice. Upon such anniversary, the MVDDS licensee must re-determine 
compliance with the minimum 10 kilometer spacing requirement based upon 
locations of qualifying NGSO FSS receivers on that anniversary date. A 
new determination of compliance with the spacing requirement shall be 
made for each succeeding anniversary of non-operation for each proposed 
MVDDS transmission site or additional antenna. This provision 
contemplates that failure to commence normal operation at a given MVDDS 
transmitting antenna site within one year of the date of NGSO FSS 
notification may require successive relocations of the proposed 
transmitter site in order to meet the minimum spacing distance as 
determined on each anniversary of non-operation.

FR 43038, June 26, 2002; 78 FR 25176, Apr. 29, 2013]



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 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

[[Page 696]]

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 
certificated 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.
    (d) LMDS subscriber transmissions. LMDS licensees shall not operate 
transmitters from subscriber locations in the 29.1-29.25 GHz band.
    (e) Existing private operational fixed wireless licensees applying 
to become common carrier wireless licensees shall comply with all 
provisions of the Communications Act and the Commission's rules. 
Applicants must take all required filings, including FCC Form 601, and 
receive all necessary Commission approval prior to operating as a common 
carrier wireless licensee. The regulatory fee associated with FCC 
wireless application Form 601 is waived for applicants who are existing 
private operational fixed licensees seeking common carrier status, 
provided that such licensees have also complied with all other 
discontinuance requirements of Title II of the Act. Applicants are 
responsible for all other Commission regulatory fees.

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 pursuant to subpart H of this part 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 entity for licensing 
under this part, regardless of individual eligibility restrictions, 
provided that the communications being 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.
    (e) Applicants licensed in the MAS frequencies after June 2, 2000, 
shall not provide service to others on a for-profit private carrier 
basis in the 928-928.85/

[[Page 697]]

952-952.85/956.25-956.45 MHz bands and the 932.25-932.5/941.25-941.5 MHz 
bands.

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) Unless specified otherwise, transmitters used in the private 
operational fixed and common carrier fixed point-to-point microwave and 
point-to-multipoint services under this part must be a type that has 
been approved for compliance under Supplier's Declaration of Conformity.
    Note 1 to paragraph (a): The verification procedure has been 
replaced by Supplier's Declaration of Conformity. Equipment previously 
authorized under subpart J of part 2 of this chapter may remain in use. 
See Sec.  2.950 of this chapter.
    (b) Any transmitter to be produced for use under the rules of this 
part may be approved under the equipment authorization procedures set 
forth in part 2 of this chapter.
    (c) Certification 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.
    (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 received a grant of certification, may continue to be used by the 
licensee without certification provided such transmitter continues 
otherwise to comply with the applicable requirements of this chapter.
    (e) Certification or Supplier's Declaration of Conformity is not 
required for portable transmitters operating with peak output power not 
greater than 250 mW. If operation of 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 manufacturer (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.
    (g) After April 1, 2005, the manufacture (except for export) or 
importation of equipment for operation in the 21,200-23,600 MHz band 
must meet:
    (1) The 0.001% frequency tolerance requirement for digital systems 
in Sec.  101.107(a) or the 0.03-0.003% frequency tolerance for analog 
systems; and
    (2) For equipment employing digital modulation techniques, the 
minimum bit rate requirements of Sec.  101.141(a).
    (h) 71,000-76,000 MHz; 81,000-86,000 MHz. For equipment employing 
digital modulation techniques, the minimum bit rate requirement is 0.125 
bit per second per Hz.
    (i) 92,000-94,000 MHz; 94,100-95,000 MHz. For equipment employing 
digital modulation techniques, the minimum bit rate requirement is 1.0 
bit per second per Hz.

2005; 82 FR 50838, Nov. 2, 2017]



Sec.  101.141  Microwave modulation.

    (a) Microwave transmitters employing digital modulation techniques 
and operating below 25.25 GHz (except for MVDDS stations in the 12,200-
12,700 MHz band) 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.
    (i) Stations authorized prior to December 1, 1988 may install 
equipment after that date with no minimum bit rate. Equipment applied 
for or authorized prior to April 1, 2005 in the 21.2-23.6

[[Page 698]]

GHz band may be installed with no minimum bit rate.
    (ii) However, any digital equipment applied for after April 1, 2005 
and equipment replacing existing equipment in the 21.2-23.6 GHz band 
must meet the bit rate standard.
    (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 certificated 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)(i) Except as noted in paragraph (a)(7) of this section, the 
payload capacity of equipment shall meet the following minimum 
efficiency standards:

----------------------------------------------------------------------------------------------------------------
                                                                Emission bandwidth 5 MHz and <=20   Emission bandwidth 20 MHz
----------------------------------------------------------------------------------------------------------------
3,700-10,550 MHz.....................  2.4 bits/second/Hertz..  4.4 bits/second/Hertz..  4.4 bits/second/Hertz.
10,550-13,250 MHz....................  2.4 bits/second/Hertz..  4.4 bits/second/Hertz..  3.0 bits/second/Hertz.

    (ii) Traffic loading payload shall exceed 50 percent of payload 
capacity within 30 months of licensing. During anomalous signal fading, 
licensees subject to the capacity and loading requirements may adjust to 
a modulation specified in their authorization if such modulation is 
necessary to allow licensees to maintain communications, even if the 
modulation will not comply with the capacity and loading requirements 
specified in this paragraph. Links that must comply with the capacity 
and loading requirements that use equipment capable of adjusting 
modulation must be designed using generally accepted multipath fading 
and rain fading models to meet the specified capacity and loading 
requirements at least 99.95% of the time, in the aggregate of both 
directions in a two-way link.
    (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 at least 50 percent of their total 
capacity is being used. For purposes of this subsection, a Fixed Service 
channel is being used if

[[Page 699]]

it is attached to a communications system that is capable of providing 
data to it at a rate that is sufficient to occupy at least 50 percent of 
the payload capacity of the Fixed Service channel, after header 
compression is applied.
    (7) Equipment placed in service after June 1, 1997 and prior to 
October 5, 2012 may comply with the provisions of Sec.  101.141(a)(3) in 
effect as of the date the equipment was placed in service.
    (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.

Sec.  101.143  Minimum path length requirements.

    (a) The distance between end points of a fixed link in the private 
operational fixed point-to-point and the common carrier fixed point-to-
point microwave services must equal or exceed the value set forth in the 
table below or the EIRP must be reduced in accordance with the equation 
set forth below:

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

    (b) For paths shorter than those specified in the table in paragraph 
(a) of this section, the EIRP shall not exceed the value derived from 
the following equation:

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

Where: EIRP = The new maximum EIRP (equivalent isotropically radiated 
          power) in dBW. MAXEIRP = Maximum EIRP as set forth in the 
          Table in Section 101.113(a).
A = Minimum path length from the Table above for the frequency band in 
          kilometers.
B = The actual path length in kilometers.

    Note to paragraph (b): For transmitters using Automatic Transmitter 
Power Control, EIRP corresponds to the maximum transmitter power 
available, not the coordinated transmit power or the nominal transmit 
power.

    (c) Upon an appropriate technical showing, applicants and licensees 
unable to meet the minimum path length

[[Page 700]]

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, 5925-7075 
MHz, and 12.7-13.25 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 (b) and (c) of this 
section are permitted to operate indefinitely, provided that the 
operation of such stations does not result in harmful interference to 
reception in these bands on board geostationary space stations.
    (b) 2655 to 2690 MHz and 5925 to 7075 MHz. No directional 
transmitting antenna utilized by a fixed station operating in these 
bands with EIRP greater than 35 dBW 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 13.25 GHz. No directional transmitting antenna utilized 
by a fixed station operating in this band with EIRP greater than 45 dBW 
may be aimed within 1.5 degrees of the geostationary-satellite orbit, 
taking into account atmospheric refraction.
    (d) Methods for calculating the azimuths to be avoided may be found

site-by-site basis.
    (28) Licensees that obtain authorizations in the 928/952/956 MHz MAS 
bands subsequent to July 1, 1999 are limited to private internal 
services, as defined in Sec.  101.1305. Incumbent operations in the 928/
952/956 MHz MAS bands, as defined in Sec.  101.1331(a), are subject to 
grandfather rights pursuant to Sec.  101.1331. The 928.85-929.0 MHz and 
959.85-960.0 MHz bands are licensed on a geographic area basis with no 
eligibility restrictions. The 928.0-928.85 MHz band paired with the 
952.0-952.85 MHz band, in addition to unpaired frequencies in the 
956.25-956.45 MHz band, are licensed on a site-by-site basis and used 
for terrestrial point-to-point and point-to-multipoint fixed and limited 
mobile operations. The 928.85-929.0 MHz band paired with the 959.85-
960.0 MHz band is licensed by Economic Area and used for terrestrial 
point-to-point and point-to-multipoint fixed operations.
    (29) Frequencies in this band are shared with stations in the 
Multipoint Distribution Service (part 21). These frequencies may be used 
for the transmission of the licensee's products and information 
services, excluding video entertainment material to the licensee's 
customers.
    (30) The frequency band 18,580-19,300 GHz is not available for new 
licensees after June 8, 2000, except for low power indoor stations in 
the band 18,820-18,870 MHz and 19,160-19,210 MHz.
    (31) This frequency band can be used for Multichannel Video 
Distribution and Data Service (MVDDS) shared with Direct Broadcast 
Satellite (DBS) Services on a co-primary non-harmful interference basis 
and on a co-primary basis with NGSO FSS satellite earth stations. 
Incumbent private operational fixed point-to-point licensees can also 
use these frequencies on a site by site basis.
    (32) Frequencies in this band are shared with stations in the fixed-
satellite service, subject to the conditions specified in footnote 15 of 
Sec.  25.202(a)(1) of this chapter, see 47 CFR 47 25.202(a)(1) n.16.
    (33) The coordination of a new 30 megahertz link in the 6,525-6,875 
MHz band should be attempted only if it cannot be accommodated in the 
5,925-6,425 MHz band.
    (34) In the bands 6,875-7,125 MHz and 12,700-13,150 MHz, links shall 
not intersect with the service areas of television pickup stations.

    (b) Frequencies normally available for assignment in this service 
are set forth with applicable limitations in the following tables: 928-
960 MHz Multiple address system (MAS) frequencies are available for the 
point-to-multipoint and point-to-point transmission of a licensee's 
products or services, excluding video entertainment material, to a 
licensee's customer or for its own internal communications. The paired 
frequencies listed in this section are used for two-way communications 
between a master station and 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. EA licensees, however, may combine contiguous channels 
without limit or justification. Site-based licensees may combine 
contiguous channels up to 50 kHz, and more than 50 kHz only upon a 
showing of adequate justification. 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

[[Page 703]]

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. 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

    (p) 12,200 to 13,150 MHz--(1) 12,000-12,700 MHz. The Commission has 
allocated the 12.2-12.7 GHz band for use by the Direct Broadcast 
Satellite Service (DBS), the Multichannel Video Distribution and Data 
Service (MVDDS), and the Non-Geostationary Satellite Orbit Fixed 
Satellite Service (NGSO FSS). MVDDS shall be licensed on a non-harmful 
interference co-primary basis to existing DBS operations and on a co-
primary basis with NGSO FSS stations in this band. MVDDS use can be on a 
common carrier and/or non-common carrier basis and can use channels of 
any desired bandwidth up to the maximum of 500 MHz provided the EIRP 
does not exceed 14 dBm per 24 megahertz. Private operational fixed 
point-to-point microwave stations authorized after September 9, 1983, 
are licensed on a non-harmful interference basis to DBS and are required 
to make

[[Page 716]]

any and all adjustments necessary to prevent harmful interference to 
operating domestic DBS receivers. Incumbent public safety licensees 
shall be afforded protection from MVDDS and NGSO FSS licensees, however 
all other private operational fixed licensees shall be secondary to DBS, 
MVDDS and NGSO FSS licensees. As of May 23, 2002, the Commission no 
longer accepts applications for new licenses for point-to-point private 
operational fixed stations in this band, however, incumbent licensees 
and previously filed applicants may file applications for minor 
modifications and amendments (as defined in Sec.  1.929 of this chapter) 
thereto, renewals, transfer of control, or assignment of license. 
Notwithstanding any other provisions, no private operational fixed 
point-to-point microwave stations are permitted to cause harmful 
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 incumbent low power, limited coverage 
systems in the band segments 12.2-12.7 GHz.
    (1) As of May 23, 2002, the Commission no longer accepts 
applications for new stations in this service and incumbent stations may 
remain in service provided they do not cause harmful interference to any 
other primary services licensed in this band as described in paragraph 
(p) of this section. However, incumbent licensees and previously filed 
applicants may file applications for minor modifications and amendments 
(as defined in Sec.  1.929 of this chapter) thereto, renewals, transfer 
of control, or assignment of license.
    (2) Prior to December 8, 2000, 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, were authorized for 
low power, limited coverage systems subject to the following provisions:
    (i) Maximum equivalent isotropically radiated power (EIRP) shall be 
55 dBm;
    (ii) The rated transmitter output power shall not exceed 0.5 watts;
    (iii) Frequency tolerance shall be maintained to within 0.01 percent 
of the assigned frequency;
    (iv) Maximum beamwidth shall not exceed 4 degrees. However, the 
sidelobe suppression criteria contained in Sec.  101.115 shall not 
apply, except that a minimum front-to-back ratio of 38 dB shall apply;
    (v) Upon showing of need, a maximum bandwidth of 12 MHz may be 
authorized per frequency assigned;
    (vi) 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);
    (vii) 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
    (viii) 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 and 24,250 to 25,250 MHz: Operation of stations 
using frequencies in these bands is permitted to the extent specified in 
this paragraph. Until November 19, 2012, stations operating in the band 
18.3-18.58 GHz that were licensed or had applications pending before the 
Commission as of November 19, 2002 shall operate on a shared co-primary 
basis with other services under parts 21, 25, 74, and 78 of this 
chapter. Until October 31, 2011, operations in the band 19.26-19.3 GHz 
and low power systems operating pursuant to paragraph (r)(10) of this 
section shall operate on a co-primary basis. Until June 8, 2010, 
stations operating in the band 18.58-18.8 GHz that were licensed or had 
applications pending before the Commission as of June 8, 2000 may 
continue those operations on a shared co-primary basis with other 
services under parts 21, 25, 74, and 78 of this chapter. Until June 8, 
2010, stations operating in the band 18.8-19.3 GHz that were licensed or 
had applications pending before the Commission as of September 18, 1998 
may continue those operations on a shared co-primary basis with other 
services under parts 21, 25, 74, and 78 of this chapter. After November 
19, 2012, stations operating in the band 18.3-18.58 GHz are not entitled 
to protection from fixed-satellite service operations and must not cause 
unacceptable interference to fixed-satellite service station operations. 
After June

[[Page 718]]

8, 2010, operations in the 18.58-19.30 GHz band are not entitled to 
protection from fixed-satellite service operations and must not cause 
unacceptable interference to fixed-satellite service station operations. 
After November 19, 2002, no applications for new stations for 47 CFR 
part 101 licenses will be accepted in the 18.3-18.58 GHz band. After 
June 8, 2000, no applications for new stations for 47 CFR part 101 
licenses will be accepted in the 18.58-19.3 GHz band. Licensees, except 
24 GHz band licensees, 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 of this 
subpart. (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, consistent 
with the above conditions related to the 18.58-19.3 GHz band.) 
Applicants for one-way spectrum from 17.7-18.58 GHz for multichannel 
video programming distribution are governed by paragraph (r)(6) of this 
section. Licensees are also allowed to use one-way (unpaired) channels 
in the 17.7-17.74 GHz sub-band to pair with other channels in the FS 
portions of the 18 GHz band where, for example, the return pair is 
already in use and therefore blocked or in TDD systems. Stations used 
for MVPD operations in the 17.7-17.8 GHz band must coordinate with the 
Federal Government before operating in the zones specified in Sec.  
1.924(e) of this chapter.

    (13) The following frequencies on channels 35-39 are available for 
point-to-multipoint systems and are available by geographic area 
licensing in the 24 GHz Service to be used as the licensee desires. The 
24 GHz spectrum can be aggregated or disaggregated and does not have to 
be used in the transmit/receive manner shown except to comply with 
international agreements along the U.S. borders. Channels 35 through 39 
are licensed in the 24 GHz Service by Economic Areas for any digital 
fixed service. Channels may be used at either nodal or subscriber 
station locations for transmit or receive but must be coordinated with 
adjacent channel and adjacent area users in accordance with the 
provisions of Sec.  101.509 of this subpart. Stations also must comply 
with international coordination agreements.

    (14) Special provision for low power systems in the 17,700-19,700 
MHz band: Notwithstanding other provisions in 47 CFR part 101 and except 
for specified areas around Washington, DC, and Denver, Colorado, 
licensees of point-to-multipoint channel pairs 25-29 identified in 
paragraph (r)(13) of this section may continue to operate in accordance 
with the requirements of Sec.  101.85 and may operate multiple low power 
transmitting devices within a defined service area. Operations are 
prohibited within 55 km when used outdoor and within 20 km when used 
indoor of the

[[Page 722]]

coordinates 38 deg.48[min] N/76 deg.52[min] W (Washington, DC area) and 
39 deg.43[min] N/104 deg.46[min] W (Denver, Colorado area). The service 
area will be a 28 kilometer omni directional radius originating from 
specified center reference coordinates. The specified center coordinates 
must be no closer than 56 kilometers from any co-channel nodal station 
or the specified center coordinates of another co-channel system. 
Applicants/licensees do not need to specify the location of each 
individual transmitting device operating within their defined service 
areas. Such operations are subject to the following requirements on the 
low power transmitting devices:
    (i) Power must not exceed one watt EIRP and 100 milliwatts 
transmitter output power;
    (ii) A frequency tolerance of 0.001% must be maintained; and
    (iii) The mean power of emissions shall be attenuated in accordance 
with the following schedule:
    (A) In any 4 kHz band, the center frequency of which is removed from 
the center frequency of the assigned channel by more than 50 percent of 
the channel bandwidth and is within the bands 18,820-18,870 MHz or 
19,160-19,210 MHz:

A = 35 + .003 (F-0.5B) dB


or,

80 dB (whichever is the lesser attenuation).

Where:

A = Attenuation (in decibels) below output power level contained within 
          the channel for a given polarization.
B = Bandwidth of channel in kHz.
F = Absolute value of the difference between the center frequency of the 
          4 kHz band measured at the center frequency of the channel in 
          kHz.

    (B) In any 4 kHz band the center frequency of which is outside the 
bands 18.820-18.870 GHz: At least 43 + 10 log P (mean output power in 
watts) decibels.
    (iv) Low power stations authorized in the band 18.8-19.3 GHz after 
June 8, 2000, are restricted to indoor use only. No new licenses will be 
authorized for applications received after April 1, 2002.
    (s) 21,200 to 23,600 MHz: 50 MHz authorized bandwidth.

\1\ Alternate channels. These channels are set aside for narrow
  bandwidth systems and should be used only if all other channels are
  blocked.
\2\ These frequencies may be assigned to low power systems, as defined
  in paragraph (8) of this section.

    (8) Special provisions for low power, limited coverage systems in 
the 21.8-22.0 GHz and 23.0-23.2 GHz band segments. Notwithstanding any 
contrary provisions in this part, the frequency band segment 21.8-22.0 
GHz paired with the frequency band segment 23.0-23.2 GHz may be 
authorized for low power, limited coverage systems subject to the 
following provisions:
    (i) The maximum EIRP shall be 55 dBm and the rated transmitter 
output power shall not exceed 0.100 Watts;
    (ii) In the band segments from 21.8-22.0 GHz and 23.0-23.2 GHz, the 
frequency tolerance for stations authorized on or before April 1, 2005 
is 0.05%. Existing licensees and pending applicants on that date may 
continue to operate after that date with a frequency tolerance of 0.05%, 
provided that it does not cause harmful interference to the operation of 
any other licensee. The frequency tolerance of Sec.  101.107(a) shall 
apply to stations applied for after April 1, 2005;
    (iii) The maximum beamwidth shall not exceed 4 degrees;
    (iv) 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;
    (v) Upon showing of need, a maximum bandwidth of 50 MHz may be 
authorized per frequency assigned;
    (vi) Radio systems authorized under the provisions of this section 
shall have no more than five hops in tandem, except upon showing of 
need, but in any event the maximum tandem length shall not exceed 40 km 
(25 miles);
    (vii) Interfering signals at the antenna terminals of station 
authorized under this section shall not exceed -90 dBm and -70 dBm 
respectively, for co-channel and adjacent channel interfering signals; 
and
    (viii) 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.
    (t) 29,100-29,250; 31,000-31,300 MHz. These frequencies are 
available for LMDS systems. Each assignment will be made on a BTA 
service area basis, and the assigned spectrum may be subdivided as 
desired by the licensee.

[[Page 726]]

    (u) 31,000-31,300 MHz. Stations licensed in this band prior to March 
11, 1997, may continue their authorized operations, subject to license 
renewal, on the condition that harmful interference will not be caused 
to LMDS operations licensed in this band after June 30, 1997. Non-LMDS 
stations licensed after March 11, 1997, based on applications refiled no 
later than June 26, 1998 are unprotected and subject to harmful 
interference from each other and from stations licensed prior to March 
11, 1997, and are licensed on a secondary basis to LMDS. In the sub-
bands 31,000-31,075 MHz and 31,225-31,300 MHz, stations initially 
licensed prior to March 11, 1997, except in LTTS, and LMDS operations 
authorized after June 30, 1997, are equally protected against harmful 
interference from each other in accordance with the provisions of Sec.  
101.103(b). For stations, except in LTTS, permitted to relocate to these 
sub-bands, the following paired frequencies are available:

    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.
    (v) [Reserved]
    (w) Fixed systems licensed, in operation, or applied for in the 
3,700-4,200, 5925-6425, 6,525-6,875, 10,550-10,680, and 10,700-11,700 
MHz bands prior to July 15, 1993, are permitted to use channel plans in 
effect prior to that date, including adding channels under those plans.
    (x) Operations on other than the listed frequencies may be 
authorized where it is shown that the objectives or requirements of the 
interference criteria prescribed in Sec.  101.105 could not otherwise be 
met to resolve the interference problems.
    (y) Special requirements for operations in the band 29.1-29.25 GHz. 
(1)(i) LMDS receive stations operating on frequencies in the 29.1-29.25 
GHz band within a radius of 75 nautical miles of the geographic 
coordinates provided by a non-GSO MSS licensee pursuant to paragraphs 
(c)(2) or (c)(3)(i) of this section (the ``feeder link earth station 
complex protection zone'') shall accept any interference caused to them 
by such earth station complexes and shall not claim protection from such 
earth station complexes.
    (ii) LMDS licensees operating on frequencies in the 29.1-29.25 GHz 
band outside a feeder link earth station complex protection zone shall 
cooperate fully and make reasonable efforts to resolve technical 
problems with the non-GSO MSS licensee to the extent that transmissions 
from the non-GSO MSS operator's feeder link earth station complex 
interfere with an LMDS receive station.
    (2) No more than 15 days after the release of a public notice 
announcing the commencement of LMDS auctions, feeder link earth station 
complexes to be licensed pursuant to Section 25.257 shall be specified 
by a set of geographic coordinates in accordance with the following 
requirements: no feeder link earth station complex may be located in the 
top eight (8) metropolitan statistical areas (``MSAs''), ranked by 
population, as defined by the Office of Management and Budget as of June 
1993, using estimated populations as of December 1992; two (2) complexes 
may be located in MSAs 9 through 25, one of which must be Phoenix, AZ 
(for a complex at Chandler, AZ); two (2) complexes may be located in 
MSAs 26 to 50; three (3) complexes may be located in MSAs 51 to 100, one 
of which must be Honolulu, Hawaii (for a complex at Waimea); and the 
three (3) remaining complexes must be located at least 75 nautical miles 
from the borders of the

[[Page 727]]

100 largest MSAs or in any MSA not included in the 100 largest MSAs. Any 
location allotted for one range of MSAs may be taken from an MSA below 
that range.
    (3)(i) Any non-GSO MSS licensee may at any time specify sets of 
geographic coordinates for feeder link earth station complexes with each 
earth station contained therein to be located at least 75 nautical miles 
from the borders of the 100 largest MSAs.
    (ii) For purposes of paragraph (c)(3)(i) of this section, non-GSO 
MSS feeder link earth station complexes shall be entitled to 
accommodation only if the affected non-GSO MSS licensee preapplies to 
the Commission for a feeder link earth station complex or certifies to 
the Commission within sixty days of receiving a copy of an LMDS 
application that it intends to file an application for a feeder link 
earth station complex within six months of the date of receipt of the 
LMDS application.
    (iii) If said non-GSO MSS licensee application is filed later than 
six months after certification to the Commission, the LMDS and non-GSO 
MSS entities shall still cooperate fully and make reasonable efforts to 
resolve technical problems, but the LMDS licensee shall not be obligated 
to re-engineer its proposal or make changes to its system.
    (4) LMDS licensees or applicants proposing to operate hub stations 
on frequencies in the 29.1-29.25 GHz band at locations outside of the 
100 largest MSAs or within a distance of 150 nautical miles from a set 
of geographic coordinates specified under paragraph (c)(2) or (c)(3)(i) 
of this section shall serve copies of their applications on all non-GSO 
MSS applicants, permitees or licensees meeting the criteria specified in 
Sec.  25.257(a). Non-GSO MSS licensees or applicants shall serve copies 
of their feeder link earth station applications, after the LMDS auction, 
on any LMDS applicant or licensee within a distance of 150 nautical 
miles from the geographic coordinates that it specified under paragraph 
(c)(2) or (c)(3)(i) of this section. Any necessary coordination shall 
commence upon notification by the party receiving an application to the 
party who filed the application. The results of any such coordination 
shall be reported to the Commission within sixty days. The non-GSO MSS 
earth station licensee shall also provide all such LMDS licensees with a 
copy of its channel plan.
    (z) 71,000-76,000 MHz; 81,000-86,000 MHz; 92,000-94,000 MHz; 94,100-
95,000 MHz. (1) Those applicants who are approved in accordance with FCC 
Form 601 will each be granted a single, non-exclusive nationwide 
license. Site-by-site registration is on a first-come, first-served 
basis. Registration will be in the Universal Licensing System until the 
Wireless Telecommunications Bureau announces by public notice, the 
implementation of a third-party database. See 47 CFR 101.1523. Links may 
not operate until NTIA approval is received. Licensees may use these 
bands for any point-to-point non-broadcast service.
    (2) Prior links shall be protected using the interference protection 
criteria set forth in section 101.105. For transmitters employing 
digital modulation techniques and operating in the 71,000-76,000 MHz or 
81,000-86,000 MHz bands, the licensee must construct a system that meets 
a minimum bit rate of 0.125 bits per second per Hertz of bandwidth. For 
transmitters that operate in the 92,000-94,000 MHz or 94,100-95,000 MHz 
bands, licensees must construct a system that meets a minimum bit rate 
of 1.0 bit per second per Hertz of bandwidth. If it is determined that a 
licensee has not met these loading requirements, then the database will 
be modified to limit coordination rights to the spectrum that is loaded 
and the licensee will lose protection rights on spectrum that has not 
been loaded.

for each authorized frequency that the booster is designed to amplify.
    (c) Class A narrowband boosters must meet the out-of-band emission 
limits of Sec.  101.111 for each narrowband channel that the booster is 
designed to amplify. Class B broadband signal boosters must meet the 
emission limits of Sec.  101.111 for frequencies outside of the 
booster's design passband.
    (d) Class B broadband signal boosters are permitted to be used only 
in confined or indoor areas such as buildings, tunnels, underground 
areas, etc., or remote areas, i.e., areas where there is little or no 
risk of interference to other users.
    (e) The licensee is given authority to operate signal boosters 
without separate authorization from the Commission. Certificated 
equipment must be employed and the licensee must ensure that all 
applicable rule requirements are met.
    (f) Licensees employing either Class A narrowband or Class B 
broadband signal boosters as defined in Sec.  101.3 are responsible for 
correcting any harmful interference that the equipment may cause to 
other systems.

connection with the preparation for the national defense. Every such 
carrier rendering any such free service must make and file, in 
duplicate, with the Commission, on or before the 31st of July and on or 
before the 31st day of January in each year, reports covering the 
periods of 6 months ending on the 30th of June and the 31st of December, 
respectively, next prior to said dates. These reports must show the 
names of the agencies to which free service was rendered pursuant to 
this rule, the general character of the communications handled for each 
agency, and the charges in dollars which would have accrued to the 
carrier for such service rendered to each agency if charges for such 
communications had been collected at the published tariff rates.



Sec.  101.303  Answers to notices of violation.

    Any person receiving official notice of a violation of the terms of 
the Communications Act of 1934, as amended, any other Federal statute or 
Executive Order pertaining to radio or wire communications or any 
international radio or wire communications treaty or convention, or 
regulations annexed thereto to which the United States is a party, or 
the rules and regulations of the Federal Communications Commission, 
must, within 10 days from such receipt, send a written answer to the 
office of the Commission originating the official notice. If an answer 
cannot be sent or an acknowledgment made within such 10-day period by 
reason of illness or other unavoidable circumstances, acknowledgment and 
answer must be made at the earliest practicable date with a satisfactory 
explanation of the delay. The answer to each notice must be complete in 
itself and may not be abbreviated by reference to other communications 
or answers to other notices. If the notice relates to some violation 
that may be due to the physical or electrical characteristics of 
transmitting apparatus, the answer must state fully what steps have been 
taken to prevent future violations, and, if any new apparatus is to be 
installed, the date such apparatus was ordered, the name of the 
manufacturer, and promised date of delivery. If the installation of such 
apparatus requires a construction permit, the file number of the 
application must be given or, if a file number has not been assigned by 
the Commission, such identification as will permit ready reference 
thereto. If the notice of violation relates to inadequate maintenance 
resulting in improper operation of the transmitter, the name and license 
number of the operator performing the maintenance must be given. If the 
notice of violation relates to some lack of attention to, or improper 
operation of, the transmitter by other employees, the reply must 
enumerate the steps taken to prevent a recurrence of such lack of 
attention or improper operation.



Sec.  101.305  Discontinuance, reduction or impairment of service.

    (a) If the public communication service provided by a station in the 
Common Carrier Radio Services, the Local Multipoint Distribution Service 
or 24 GHz Service is involuntarily discontinued, reduced or impaired for 
a period exceeding 48 hours, the station licensee must promptly notify 
the Commission. In every such case, the licensee must furnish full 
particulars as to the reasons for such discontinuance,

[[Page 731]]

reduction or impairment of service, including a statement as to when 
normal service is expected to be resumed. When normal service is 
resumed, prompt notification thereof must be given Commission.
    (b) No station licensee subject to title II of the Communications 
Act of 1934, as amended, may voluntarily discontinue, reduce or impair 
public communication service to a community or part of a community 
without obtaining prior authorization from the Commission pursuant to 
the procedures set forth in part 63 of this chapter. In the event that 
permanent discontinuance of service is authorized by the Commission, the 
station license is terminated; except that station licenses in the Local 
Multipoint Distribution Service and 24 GHz Service are not terminated if 
the discontinuance is a result of a change of status by the licensee 
from common carrier to non-common carrier pursuant to Sec.  1.929 of 
this chapter.
    (c) Any licensee not subject to title II of the Communications Act 
of 1934, as amended, who voluntarily discontinues, reduces or impairs 
public communication service to a community or a part of a community 
must notify the Commission within 7 days thereof. In the event of 
permanent discontinuance of service, the station license is 
automatically terminated; except that station licenses in the Local 
Multipoint Distribution Service and 24 GHz Service are not terminated if 
the discontinuance is a result of a change of status by the licensee 
from non-common carrier to common carrier pursuant to Sec.  1.929 of 
this chapter.
    (d) If any common carrier radio frequency should not be used to 
render any service as authorized during a consecutive period of twelve 
months at any time after construction is completed under circumstances 
that do not fall within the provisions of paragraph (a), (b), or (c) of 
this section, or, if removal of equipment or facilities has rendered the 
station not operational, the licensee must, within thirty days of the 
end of such period of nonuse:
    (1) Cancel the station license (or licenses); or
    (2) File an application for modification of the license (or 
licenses) to delete the unused frequency (or frequencies); or
    (3) Request waiver of this rule and demonstrate either that the 
frequency will be used (as evidenced by appropriate requests for 
service, etc.) within six months of the end of the initial period of 
nonuse, or that the frequency will be converted to allow rendition of 
other authorized public services within one year of the end of the 
initial period of nonuse by the filing of appropriate applications 
within six months of the end of the period of nonuse.

[68 FR 4961, Jan. 31, 2003]



Sec.  101.509  Interference protection criteria.

    (a) As a condition for use of frequencies in this service each 
licensee is required to:
    (1) Engineer the system to be reasonably compatible with adjacent 
and co-channel operations in the same or adjacent areas on all 
frequencies; and
    (2) Cooperate fully and in good faith to resolve whatever potential 
interference and transmission security problems may be present in 
adjacent and co-channel operations.
    (b) All harmful interference to other users of co-channel and 
adjacent channel use in the same or adjacent geographical area are 
prohibited. In areas where Economic Areas are in close proximity, 
careful consideration should be given to minimum power requirements and 
to the location, height, and radiation pattern of the transmitting and 
receiving antennas. Licensees are expected to cooperate fully in 
attempting to resolve problems of potential interference before bringing 
the matter to the attention of the Commission.
    (c) Licensee shall coordinate their facilities whenever the 
facilities have optical line-of-sight into other licensees' areas or are 
within the same geographic area. Licensees are encouraged to develop 
operational agreements with relevant licensees in the same or adjacent 
areas. Incumbent SMSA licensee(s) shall retain exclusive rights to its 
channel(s) within its SMSA and must be protected.
    (d) Licensees shall comply with the appropriate coordination 
agreements between the United States and Canada and the United States 
and Mexico concerning cross-border sharing and use of the 24 GHz bands 
which may require using channels pairs in accordance with the table in 
Sec.  101.147(r)(9).
    (e) The Commission recommends that coordination is not necessary if 
the power flux density (pfd) at the boundary of the relevant adjacent 
area is lower than -114 dBW/m\2\ in any 1 MHz. This value can be changed 
and agreed upon by both coordinating parties. Licensees should be able 
to deploy with a pfd up to -94 dBW/m\2\ in any 1 MHz at the boundary of 
the relevant adjacent area without negatively affecting the successful 
operations of the adjacent area licensee.

Sec.  101.1331  Treatment of incumbents.

    (a) Any MAS station licensed by the Commission prior to July 1, 1999 
in the 928.0-928.85 MHz/952.0-952.85 MHz/956.25-956.45 MHz and 928.85-
929.0 MHz/959.85-960.0 MHz bands, as well as assignments or transfers of 
such stations approved by the Commission and consummated as of January 
19, 2000, shall be considered incumbent.
    (b) Incumbent operators in the 928.0-928.85 MHz/952.0-952.85 MHz/
956.25-956.45 MHz bands are grandfathered as of January 19, 2000, and 
may continue to operate and expand their systems pursuant to the 
interference protection and co-channel spacing criteria contained in 
Sec.  101.105.
    (1) MAS operators are prohibited from acquiring additional 
frequencies in the 928.0-928.85 MHz/952.0-952.85 MHz/956.25-956.45 MHz 
bands and the 932.25625-932.49375 MHz/941.25625-941.49375 MHz bands for 
the purpose of expanding private carrier service and from changing the 
use of their frequencies in any manner that is inconsistent with this 
part. Refer to Sec.  101.147 for designated uses.
    (2) Incumbent operators in the 928.0-928.85 MHz/952.0-952.85 MHz/
956.25-956.45 MHz bands will include incumbents as defined in Sec.  
101.1331(a), as well as, their transferees and/or assignees and the 
successors of the transferees and/or assignees and retain their 
grandfathered status, provided that the use of the MAS frequencies 
remains unchanged from that of the transferor and/or assignor of the 
license.
    (c) Incumbent operators in the 928.85-929.0/959.85-960.0 MHz bands 
are grandfathered as of January 19, 2000, and may expand their systems 
provided that the signal level of the additional transmitter(s) does not 
increase the composite contour that occurs at a 40.2 kilometer (25-mile) 
radius from the center of each master station transmitter site. 
Incumbent operators and geographic area licensees may negotiate 
alternative criteria.
    (d) The frequencies associated with incumbent authorizations in the 
928/959 MHz bands that have cancelled automatically or otherwise been 
recovered by the Commission will automatically revert to the applicable 
EA licensee.
    (e) The frequencies associated with incumbent authorizations in the 
928/952/956 MHz bands that have cancelled automatically will revert to 
the Commission.

Sec.  101.1333  Interference protection criteria.

    (a) Frequency coordination. All EA licensees are required to 
coordinate their frequency usage with co-channel adjacent area licensees 
and all other affected parties.
    (b) EA licensees are prohibited from exceeding a signal strength of 
40 dB[micro]V/m at their service area boundaries, unless a higher signal 
strength is agreed to by all affected co-channel, adjacent area 
licensees.
    (c) EA licensees are prohibited from exceeding a signal strength of 
40 dB[micro]V/m at incumbent licensees' 40.2 kilometer (25-mile) radius 
composite contour specified in Sec.  101.1331(c).
    (d) In general, licensees shall comply with the appropriate 
coordination agreements between the United States and Canada and the 
United States and

[[Page 748]]

Mexico concerning cross-border sharing and use of the applicable MAS 
frequencies.
    (1) Canada--932.0-932.25 MHz and 941.0-941.25 MHz. (i) Within Lines 
A, B, C, and D, as defined in Sec.  1.928(e) of this chapter, along the 
U.S./Canada border, U.S. stations operating in the 932.0-932.25 MHz and 
941.0-941.25 MHz bands are on a secondary basis and may operate provided 
that they shall not transmit a power flux density (PFD) at the border 
greater than -100 dBW/m\2\ nor -94 dBW/m\2\, respectively. The U.S. has 
full use of the frequencies in these regions up to the border in the 
bands 932.25-932.50 MHz and 941.25-941.50 MHz, and Canadian stations may 
operate on a secondary basis provided they do not exceed the respective 
PFDs shown above. PFD can be determined using the following formula: PFD 
(dBW/m\2\) = 10 log [EIRP/4[pi](D\2\], where EIRP is in watts, D is in 
meters, and the power is relative to an isotropic radiator. The 
technical parameters are also limited by tables 1 and 2:

    Note to Table 2: This information is from the Arrangement between 
the Federal Communications Commission and the National 
Telecommunications and Information Administration of the United States 
of America, and Industry Canada concerning the use of the bands 932 to 
935 MHz and 941 to 944 MHz along the United States-Canada border signed 
in 1994. This agreement also lists grandfathered stations that must be 
protected.

    (2) Canada--928-929 MHz and 952-960 MHz. Between Lines A and B and 
between Lines C and D, as defined in Sec.  1.928(e) of this chapter, 
along the U.S./Canada border, U.S. stations operating in the 928.50-
928.75 MHz and 952.50-952.75 MHz bands are on an unprotected basis and 
may operate provided that they shall not transmit a power flux density 
(PFD) at or beyond the border greater than -100 dBW/m\2\. The U.S. has 
full use of the frequencies in these regions up to the border in the 
bands 928.25-928.50 MHz and 952.25-952.50 MHz, and Canadian stations may 
operate on an unprotected basis provided they do not exceed the PFD 
above. Frequencies in the bands 928.00-928.25 MHz, 928.75-929.00 MHz, 
952.00-952.25 MHz, and 952.75-952.85 MHz are available for use on a 
coordinated, first-in-time, shared basis subject to protecting 
grandfathered stations. New stations must provide a minimum of 145 km 
(90 miles) separation or alternatively limit the actual PFD of the 
proposed station to -100 dBW/m\2\, at the existing co-channel master 
stations of the other country, or as mutually agreed upon on a case-by-
case basis. Coordination is not required if the PFD at the border is 
lower than -100 dBW/m\2\. The technical criteria are also limited by the 
following:

Maximum EIRP for master stations in the MHz band: 1000 watts (30 dBW) 
    952-953
Maximum EIRP for fixed remote stations or stations in the 928-929 MHz 
    band: 50 watts (17 dBW) master
Maximum EIRP for mobile master stations: 25 watts (14 dBW)
Maximum antenna height above average master or control stations: 152 m 
    at 1000 watts terrain for EIRP, power derated in accordance with the 
    following table:

Concerning the Use of the Bands 928 to 929 MHz and 952 to 953 MHz along 
the United States-Canada Border signed in 1991. This agreement also 
lists grandfathered stations that must be protected.

    (3) Mexico. Within 113 kilometers of the U.S./Mexico border, U.S. 
stations operating in the 932.0-932.25 MHz and 941.0-941.25 MHz bands 
are on a secondary basis (non-interference to Mexican primary licensees) 
and may operate provided that they shall not transmit a power flux 
density (PFD) at or beyond the border greater than -100 dBW/m\2\. Upon 
notification from the Commission, U.S. licensees must take proper 
measures to eliminate any harmful interference caused to Mexican primary 
assignments. The U.S. has full use of the frequencies in these regions 
up to the border in the bands 932.25-932.50 MHz and 941.25-941.50 MHz, 
and Mexican stations may operate on a secondary basis (non-interference 
to U.S. primary licensees) provided they do not exceed the PFD shown 
above. Stations using the 932-932.5 MHz band shall be limited to the 
maximum effective isotropic radiated power of 50 watts (17 dBW). 
Stations using the 941-941.5 MHz band shall meet the limits in the

Subpart P_Multichannel Video Distribution and Data Service Rules for the 
                           12.2	12.7 GHz Band

    Source: 69 FR 31746, June 7, 2004, unless otherwise noted.



Sec.  101.1401  Service areas.

    Multichannel Video Distribution and Data Service (MVDDS) is licensed 
on the basis of Designated Market Areas (DMAs). The 214 DMA service 
areas are based on the 210 Designated Market Areas delineated by Nielsen 
Media Research and published in its publication entitled U.S. Television 
Household Estimates, September 2002, plus four FCC-defined DMA-like 
service areas.
    (a) Alaska--Balance of State (all geographic areas of Alaska not 
included in Nielsen's three DMAs for the state: Anchorage, Fairbanks, 
and Juneau);
    (b) Guam and the Northern Mariana Islands;
    (c) Puerto Rico and the United States Virgin Islands; and
    (d) American Samoa.



Sec.  101.1403  Broadcast carriage requirements.

    MVDDS licensees are not required to provide all local television 
channels to subscribers within its area and thus are not required to 
comply with the must-carry rules, nor the local signal carriage 
requirements of the Rural Local Broadcast Signal Act. See Multichannel 
Video and Cable Television Service Rules, Subpart D (Carriage of 
Television Broadcast Signals), 47 CFR 76.51-76.70. If an MVDDS licensee 
meets the statutory definition of Multiple Video Programming Distributor 
(MVPD), the retransmission consent requirement of section 325(b)(1) of 
the Communications Act of 1934, as amended (47 U.S.C. 325(b)(1)) shall 
apply to that MVDDS licensee. Any MVDDS licensee that is an MVPD must 
obtain the prior express authority of a broadcast station before 
retransmitting that station's signal,

[[Page 750]]

subject to the exceptions contained in section 325(b)(2) of the 
Communications Act of 1934, as amended (47 U.S.C. 325(b)(2)). Network 
nonduplication, syndicated exclusivity, sports blackout, and leased 
access rules shall not be imposed on MVDDS licensees.



Sec.  101.1405  Channeling plan.

    Each license shall have one spectrum block of 500 megahertz per 
geographic area that can be divided into any size channels. 
Disaggregation is not allowed.



Sec.  101.1407  Permissible operations for MVDDS.

    MVDDS licensees must use spectrum in the 12.2-12.7 GHz band for any 
digital fixed non-broadcast service (broadcast services are intended for 
reception of the general public and not on a subscribership basis) 
including one-way direct-to-home/office wireless service. Mobile and 
aeronautical services are not authorized. Two-way services may be 
provided by using other spectrum or media for the return or upstream 
path.



Sec.  101.1409  Treatment of incumbent licensees.

    Terrestrial private operational fixed point-to-point licensees in 
the 12.2-12.7 GHz band which were licensed prior to MVDDS or NGSO FSS 
satellite stations are incumbent point-to-point stations and are not 
entitled to protection from harmful interference caused by later MVDDS 
or NGSO FSS entrants in the 12.2-12.7 GHz band, except for public safety 
stations which must be protected. MVDDS and NGSO FSS operators have the 
responsibility of resolving any harmful interference problems that their 
operations may cause to these public safety incumbent point-to-point 
operations in the 12.2-12.7 GHz band. Incumbent public safety 
terrestrial point-to-point licensees may only make minor changes to 
their stations without losing this protection. This does not relieve 
current point-to-point licensees of their obligation to protect BSS 
operations in the subject frequency band. All point-to-point 
applications, including low-power operations, for new licenses, major 
amendments to pending applications, or major modifications to existing 
licenses for the 12.2-12.7 GHz band are no longer accepted except for 
renewals and changes in ownership. See Sec.  1.929 of this chapter for 
definitions of major and minor changes.



Sec.  101.1411  Regulatory status and eligibility.

    (a) MVDDS licensees are permitted to provide one-way video 
programming and data services on a non-common carrier and/or on a common 
carrier basis. MVDDS is not required to be treated as a common carrier 
service unless it is providing non-Internet voice and data services 
through the public switched network.
    (b) MVDDS licensees in the 12.2-12.7 GHz band are subject to the 
requirements set forth in Sec.  101.7.
    (c) Any entity, other than one precluded by Sec. Sec.  101.7 and 
101.1412, is eligible for authorization to provide MVDDS under this 
part. Authorization will be granted upon proper application filing in 
accordance with the Commission's rules.



Sec.  101.1412  MVDDS eligibility restrictions for cable operators.

    (a) Eligibility for MVDDS license. No cable operator, nor any entity 
owning an attributable interest in a cable operator, shall have an 
attributable interest in an MVDDS license if such cable operator's 
service area significantly overlaps the MVDDS license area, as 
``significantly overlaps'' is defined in paragraph (e) of this section.
    (b) Definition of cable operator. For the purposes of paragraph (a) 
of this section, the term ``cable operator'' means a company that is 
franchised to provide cable service, as defined in 47 CFR 76.5(ff) of 
this chapter, in all or part of the MVDDS license area.
    (c) For the purpose of this section, the term ``MVPD household'' 
refers to a household that subscribes to one or more Multichannel Video 
Program Distributors (MVPDs), as defined in 47 CFR 76.1000(e) of this 
chapter.
    (d) Waiver of restriction. Upon completion of the initial award of 
an MVDDS license, a cable operator may petition for a waiver of the 
restriction on eligibility based upon a showing

[[Page 751]]

that changed circumstances or new evidence indicate that no significant 
likelihood of substantial competitive harm will result from the operator 
retaining an attributable interest in the MVDDS license.
    (e) Significant overlap with service area. For purposes of paragraph 
(a) of this section, significant overlap occurs when a cable operator's 
subscribers in the MVDDS license area make up thirty-five percent or 
more of the MVPD households in that MVDDS license area.
    (f) Definition of attributable interest. For purposes of paragraph 
(a) of this section, an entity shall be considered to have an 
attributable interest in a cable operator or MVDDS licensee pursuant to 
the following criteria:
    (1) A controlling interest shall constitute an attributable 
interest. Controlling interest means majority voting equity ownership, 
any general partnership interest, or any means of actual working control 
(including negative control) over the operation of the entity, in 
whatever manner exercised.
    (2) Any general partnership interest in a partnership;
    (3) Partnership and similar ownership interests (including limited 
partnership interests) amounting to 20 percent or more of the total 
partnership interests, calculated according to both the percentage of 
equity paid in and the percentage of distribution of profits and losses;
    (4) Any stock interest amounting to 20 percent or more of the 
outstanding voting stock of an entity;
    (5) Any voting or non-voting stock interest, amounting to 20 percent 
or more of the total outstanding stock of an entity;
    (6) Stock interests held in trust that exceed the limit set forth in 
paragraph (f) of this section shall constitute an attributable interest 
of any person who holds or shares the power to vote such stock, of any 
person who has the sole power to sell such stock, and, in the case of 
stock held in trust, of any person who has the right to revoke the trust 
at will or to replace the trustee at will. If the trustee has a 
familial, personal, or extra-trust business relationship to the grantor 
or the beneficiary, the stock interests held in trust shall constitute 
an attributable interest of such grantor or beneficiary, as appropriate.
    (7) Debt and interests such as warrants and convertible debentures, 
options, or other interests (except non-voting stock) with rights of 
conversion to voting interests shall not constitute attributable 
interests unless and until conversion is effected.
    (8) An interest in a Limited Liability Company (LLC) or Registered 
Limited Liability Partnership (RLLP) amounting to 20 percent or more, 
shall constitute an attributable interest of each such limited partner.
    (9) Officers and directors of a cable operator, an MVDDS licensee, 
or an entity that controls such cable operator or MVDDS licensee, shall 
be considered to have an attributable interest in such cable operator or 
MVDDS licensee.
    (10) Ownership interests that are held indirectly by any party 
through one or more intervening corporations or other entities shall be 
determined by successive multiplication of the ownership percentages for 
each link in the vertical ownership chain and application of the 
relevant attribution benchmark to the resulting product, except that, if 
the ownership for any interest in any link in the chain exceeds 50 
percent or represents actual control, it shall be treated as if it were 
a 100 percent interest.
    (11) Any person who manages the operations of a cable operator or an 
MVDDS licensee pursuant to a management agreement shall be considered to 
have an attributable interest in such cable operator or MVDDS licensee, 
if such person or its affiliate has authority to make decisions or 
otherwise engage in practices or activities that determine, or 
significantly influence:
    (i) The nature or types of services offered by such entity;
    (ii) The terms upon which such services are offered; or
    (iii) The prices charged for such services.
    (12) Any person or its affiliate who enters into a joint marketing 
arrangement with a cable operator, an MVDDS licensee, or an affiliate of 
such entity, shall be considered to have an attributable interest in 
such cable operator, MVDDS licensee, or affiliate, if such

[[Page 752]]

person or its affiliate has authority to make decisions or otherwise 
engage in practices or activities that determine:
    (i) The nature or types of services offered by such entity;
    (ii) The terms upon which such services are offered; or
    (iii) The prices charged for such services.
    (g) Divestiture. Any cable operator, or any entity owning an 
attributable interest in a cable operator, that would otherwise be 
barred from acquiring an attributable interest in an MVDDS license by 
the eligibility restriction in paragraph (a) of this section, may be a 
party to an MVDDS application (i.e., have an attributable interest in 
the applicant), and such applicant will be eligible for an MVDDS 
license, pursuant to the divestiture procedures set forth in paragraphs 
(g)(1) through (g)(6) of this section.
    (1) Divestiture shall be limited to the following prescribed means:
    (i) An MVDDS applicant holding an attributable interest in a cable 
operator may divest such interest in the cable company.
    (ii) Other MVDDS applicants disqualified under paragraph (a) of this 
section, will be permitted to:
    (A) Partition and divest that portion of the existing service area 
that causes it to exceed the overlap restriction in paragraph (a) of 
this section, subject to applicable regulations of state and local 
governments; or
    (B) Partition and divest that portion of the MVDDS geographic 
service area that exceeds the overlap restriction in paragraph (a) of 
this section.
    (iii) Divestiture may be to an interim trustee if a buyer has not 
been secured in the required period of time, as long as the MVDDS 
applicant has no interest in or control of the trustee and the trustee 
may dispose of the license as it sees fit.
    (2) The MVDDS applicant shall certify as an exhibit to its short 
form application that it and all parties to the application will come 
into compliance with paragraph (a) of this section.
    (3) If such MVDDS applicant is a successful bidder in an auction, it 
must submit with its long-form application a signed statement describing 
its efforts to date and future plans to come into compliance with the 
eligibility restrictions in paragraph (a) of this section.
    (4) If such an MVDDS applicant is otherwise qualified, its 
application will be granted subject to a condition that the applicant 
shall come into compliance with the eligibility restrictions in 
paragraph (a) within ninety (90) days of final grant of such MVDDS 
license.
    (5) An MVDDS applicant will be considered to have come into 
compliance with paragraph (a) of this section if:
    (i) In the case of the divestiture of a portion of an MVDDS license 
service area, it has successfully completed the assignment or transfer 
of control of the requisite portion of the MVDDS geographic service 
area.
    (ii) In all other cases, it has submitted to the Commission a signed 
certification that it has come into compliance with paragraph (a) of 
this section by the following means, identified in such certification:
    (A) By divestiture of a disqualifying interest in a cable operator, 
identified in terms of the interest owned, the owner of such interest 
(and, if such owner is not the applicant itself, the relationship of the 
owner to the applicant), the name of the party to whom such interest has 
been divested, and the date such divestiture was executed; or
    (B) By divestiture of the requisite portion of the cable operator's 
existing service area, identified in terms of the name of the party to 
whom such interest has been divested, the date such divestiture was 
executed, the name of any regulatory agency that must approve such 
divestiture, and the date on which an application was filed for this 
purpose with the regulatory agency.
    (6) If no such certification or application is tendered to the 
Commission within ninety (90) days of final grant of the initial 
license, the Commission may cancel or rescind the license automatically, 
shall retain all monies paid to the Commission, and, based on the facts 
presented, shall take any other action it may deem appropriate.

    Note to Sec.  101.1412: Waivers of Sec.  101.1412(f) may be granted 
upon an affirmative showing:
    (a) That the interest holder has less than a fifty percent voting 
interest in the licensee and there is an unaffiliated single holder of a 
fifty percent or greater voting interest;

[[Page 753]]

    (b) That the interest holder is not likely to affect the local 
market in an anticompetitive manner;
    (c) That the interest holder is not involved in the operations of 
the licensee and does not have the ability to influence the licensee on 
a regular basis; and
    (d) That grant of a waiver is in the public interest because the 
benefits to the public of common ownership outweigh any potential 
anticompetitive harm to the market.

[69 FR 31746, June 7, 2004, as amended at 69 FR 59146, Oct. 4, 2004]



Sec.  101.1413  License term and construction requirements.

    (a) The MVDDS license term is ten years, beginning on the date of 
the initial authorization grant.
    (b) As a construction requirement, MVDDS licensees must make a 
showing of substantial service at the end of five years into the license 
period and ten years into the license period. The substantial service 
requirement is defined as a service that is sound, favorable, and 
substantially above a level of mediocre service which might minimally 
warrant renewal. At the end of five years into the license term and ten 
years into the license period, the Commission will consider factors such 
as:
    (1) Whether the licensee's operations service niche markets or focus 
on serving populations outside of areas serviced by other MVDDS 
licensees;
    (2) Whether the licensee's operations serve populations with limited 
access to telecommunications services; and
    (3) A demonstration of service to a significant portion of the 
population or land area of the licensed area.
    (c) The renewal application of an MVDDS licensee is governed by 
Sec.  1.949 of this chapter.

[69 FR 31746, June 7, 2004, as amended at 82 FR 41549, Sept. 1, 2017]



Sec.  101.1415  Partitioning and disaggregation.

    (a) MVDDS licensees are permitted to partition licensed geographic 
areas along county borders (Parishes in Louisiana or Territories in 
Alaska). Disaggregation will not be permitted by MVDDS licensees in the 
12.2-12.7 GHz band. ``Partitioning'' is the assignment of geographic 
portions of a license along geopolitical or other boundaries. 
``Disaggregation'' is the assignment of discrete portions or ``blocks'' 
of spectrum licensed to a geographic licensee or qualifying entity.
    (b) Eligibility. (1) Parties seeking approval for partitioning shall 
request from the Commission an authorization for partial assignment of a 
license pursuant to Sec.  1.948 of this chapter.
    (2) MVDDS licensees may apply to the Commission to partition their 
licensed geographic service areas to eligible entities and are free to 
partition their licensed spectrum at any time following the grant of a 
license.
    (3) Any existing frequency coordination agreements shall convey with 
the assignment of the geographic area or spectrum, and shall remain in 
effect for the term of the agreement unless new agreements are reached.
    (c) Technical standards. (1) Partitioning. In the case of 
partitioning, applicants and licensees must file FCC Form 603 pursuant 
to Sec.  1.948 of this chapter and list the partitioned service area on 
a schedule to the application.
    (2) The geographic coordinates must be specified in degrees, 
minutes, and seconds to the nearest second of latitude and longitude and 
must be based upon the 1983 North American Datum (NAD83).
    (d) Unjust enrichment. 12 GHz licensees that received a bidding 
credit and partition their licenses to entities not meeting the 
eligibility standards for such a bidding credit, will be subject to the 
provisions concerning unjust enrichment as set forth in Sec.  1.2111 of 
this chapter.
    (e) License term. The MVDDS license term is ten years, beginning on 
the date of the initial authorization grant. The license term for a 
partitioned license area shall be the remainder of the original 
licensee's license term as provided for in Sec.  101.1413.

[69 FR 31746, June 7, 2004, as amended at 82 FR 41549, Sept. 1, 2017]



Sec.  101.1417  Annual report.

    Each MVDDS licensee shall file with the Broadband Division of the 
Wireless Telecommunications Bureau of the Commission two copies of a 
report by March 1 of each year for the preceding calendar year. This 
report must include the following:
    (a) Name and address of licensee;

[[Page 754]]

    (b) Station(s) call letters and primary geographic service area(s); 
and
    (c) The following statistical information for the licensee's station 
(and each channel thereof):
    (1) The total number of separate subscribers served during the 
calendar year;
    (2) The total hours of transmission service rendered during the 
calendar year to all subscribers;
    (3) The total hours of transmission service rendered during the 
calendar year involving the transmission of local broadcast signals; and
    (4) A list of each period of time during the calendar year in which 
the station rendered no service as authorized, if the time period was a 
consecutive period longer than 48 hours.



Sec.  101.1421  Coordination of adjacent area MVDDS stations.

    (a) MVDDS licensees in the 12.2-12.7 GHz band are required to 
develop sharing and protection agreements based on the design and 
architecture of their systems, in order to ensure that no harmful 
interference occurs between adjacent geographical area licensees. MVDDS 
licensees shall:
    (1) Engineer systems to be reasonably compatible with adjacent and 
co-channel operations in the adjacent areas on all its frequencies; and
    (2) Cooperate fully and in good faith to resolve interference and 
transmission problems that are present on adjacent and co-channel 
operations in adjacent areas.
    (b) Harmful interference to public safety stations, co-channel MVDDS 
stations operating in adjacent geographic areas, and stations operating 
on adjacent channels to MVDDS stations is prohibited. In areas where the 
DMAs are in close proximity, careful consideration should be given to 
power requirements and to the location, height, and radiation pattern of 
the transmitting and receiving antennas. Licensees are expected to 
cooperate fully in attempting to resolve problems of potential 
interference before bringing the matter to the attention of the 
Commission.
    (c) Licensees shall coordinate their facilities whenever the 
facilities have optical line-of-sight into other licensees' areas or are 
within the same geographic area. Licensees are encouraged to develop 
operational agreements with relevant licensees in the adjacent 
geographic areas. Incumbent public safety POFS licensee(s) shall retain 
exclusive rights to its channel(s) within the relevant geographical 
areas and must be protected in accordance with the procedures in Sec.  
101.103. A list of public safety incumbents is attached as Appendix I to 
the Memorandum Opinion and Order and Second Report and Order, Docket 98-
206, released May 23, 2002. Please check with the Commission for any 
updates to that list.



Sec.  101.1423  Canadian and Mexican coordination.

    Pursuant to Sec.  2.301 of this chapter, MVDDS systems in the United 
States within 56 km (35 miles) of the Canadian and Mexican border will 
be granted conditional licenses, until final international agreements 
are approved. These systems may not cause harmful interference to 
stations in Canada or Mexico. MVDDS stations must comply with the 
procedures outlined under Sec. Sec.  101.147(p) and 1.928(f)(1) and 
(f)(2) of this chapter until final international agreements concerning 
MVDDS are signed. Section 1.928(f) of this chapter states that 
transmitting antennas can be located as close as five miles (eight 
kilometers) of the border if they point within a sector of 160 degrees 
away from the border, and as close as thirty-five miles (fifty-six km) 
of the border if they point within a sector of 200 degrees toward the 
border without coordination with Canada. MVDDS licensees shall apply 
this method near the Canadian and Mexican borders. No stations are 
allowed within 5 miles of the borders.



Sec.  101.1425  RF exposure.

    MVDDS stations in the 12.2-12.7 GHz frequency band shall ensure 
compliance with the Commission's radio frequency exposure requirements 
in Sec.  1.1307(b) of this chapter. An Environmental Assessment may be 
required if RF radiation from the proposed facilities would, in 
combination with radiation from other sources, cause RF power density or 
field strength in an accessible area to exceed the applicable

[[Page 755]]

limits specified in Sec.  1.1310 of this chapter.

[85 FR 18151, Apr. 1, 2020]



Sec.  101.1427  MVDDS licenses subject to competitive bidding.

    Mutually exclusive initial applications for MVDDS licenses in the 
12.2-12.7 GHz band are subject to competitive bidding. The general 
competitive bidding procedures set forth in part 1, subpart Q of this 
chapter will apply unless otherwise provided in this subpart.



Sec.  101.1429  Designated entities.

    (a) Eligibility for small business provisions. (1) A very small 
business is an entity that, together with its controlling interests and 
affiliates, has average annual gross revenues not exceeding $3 million 
for the preceding three years.
    (2) A small business is an entity that, together with its 
controlling interests and affiliates, has average annual gross revenues 
not exceeding $15 million for the preceding three years.
    (3) An entrepreneur is an entity that, together with its controlling 
interests and affiliates, has average annual gross revenues not 
exceeding $40 million for the preceding three years.
    (b) Bidding credits. A winning bidder that qualifies as a very small 
business, as defined in this section, or a consortium of very small 
businesses may use the bidding credit specified in Sec.  1.2110(f)(2)(i) 
of this chapter. A winning bidder that qualifies as a small business, as 
defined in this section, or a consortium of small businesses may use the 
bidding credit specified in Sec.  1.2110(f)(2)(ii) of this chapter. A 
winning bidder that qualifies as an entrepreneur, as defined in this 
section, or a consortium of entrepreneurs may use the bidding credit 
specified in Sec.  1.2110(f)(2)(iii) of this chapter.



Sec.  101.1440  MVDDS protection of DBS.

    (a) An MVDDS licensee shall not begin operation unless it can ensure 
that the EPFD from its transmitting antenna at all DBS customers of 
record locations is below the values listed for the appropriate region 
in Sec.  101.105(a)(4)(ii). Alternatively, MVDDS licensees may obtain a 
signed written agreement from DBS customers of record stating that they 
are aware of and agree to their DBS system receiving MVDDS signal levels 
in excess of the appropriate EPFD limits specified in Sec.  
101.105(a)(4)(ii). DBS customers of record are those who had their DBS 
receive antennas installed prior to or within the 30 day period after 
notification to the DBS operator by the MVDDS licensee of the proposed 
MVDDS transmitting antenna site.
    (b) MVDDS licensees are required to conduct a survey of the area 
around its proposed transmitting antenna site to determine the location 
of all DBS customers of record that may potentially be affected by the 
introduction of its MVDDS service. The MVDDS licensee must assess 
whether the signal levels from its system, under its deployment plans, 
would exceed the appropriate EPFD levels in Sec.  101.105(a)(4)(ii) at 
any DBS customer of record location. Using EPFD calculations, terrain 
and building structure characteristics, and the survey results, an MVDDS 
licensee must make a determination of whether its signal level(s) will 
exceed the EPFD limit at any DBS customer of record sites. To assist in 
making this determination, the MVDDS provider can use the EPFD contour 
model developed by the Commission and described in Appendix J of the 
Memorandum Opinion and Order and Second Report and Order, ET Docket 98-
206 or on the OET website at http://www.fcc.gov/ oet/dockets/et98-206.
    (c) If the MVDDS licensee determines that its signal level will 
exceed the EPFD limit at any DBS customer site, it shall take whatever 
steps are necessary, up to and including finding a new transmit site, to 
ensure that the EPFD limit will not be exceeded at any DBS customer 
location.
    (d) Coordination between MVDDS and DBS licensees. (1) At least 90 
days prior to the planned date of MVDDS commencement of operations, the 
MVDDS licensee shall provide the following information to the DBS 
licensee(s):
    (i) Geographic location (including NAD 83 coordinates) of its 
proposed station location;
    (ii) Maximum EIRP of each transmitting antenna system;
    (iii) Height above ground level for each transmitting antenna;

[[Page 756]]

    (iv) Antenna type along with main beam azimuth and altitude 
orientation information, and description of the antenna radiation 
pattern;
    (v) Description of the proposed service area; and
    (vi) Survey results along with a technical description of how it 
determined compliance with the appropriate EPFD level at all DBS 
subscriber locations.
    (2) No later than forty-five days after receipt of the MVDDS system 
information in paragraph (d)(1) of this section, the DBS licensee(s) 
shall provide the MVDDS licensee with a list of only those new DBS 
customer locations that have been installed in the 30-day period 
following the MVDDS notification and that the DBS licensee believes may 
receive harmful interference or where the prescribed EPFD limits may be 
exceeded. In addition, the DBS licensee(s) could indicate agreement with 
the MVDDS licensee's technical assessment, or identify DBS customer 
locations that the MVDDS licensee failed to consider or DBS customer 
locations where they believe the MVDDS licensee erred in its analysis 
and could exceed the prescribed EPFD limit.
    (3) Prior to commencement of operation, the MVDDS licensee must take 
into account any new DBS customers or other relevant information 
provided by DBS licensees in response to the notification in paragraph 
(d)(1) of this section.
    (e) Beginning thirty days after the DBS licensees are notified of a 
potential MVDDS site in paragraph (d)(1) of this section, the DBS 
licensees are responsible for providing information they deem necessary 
for those entities who install all future DBS receive antennas on its 
system to take into account the presence of MVDDS operations so that 
these DBS receive antennas can be located in such a way as to avoid the 
MVDDS signal. These later installed DBS receive antennas shall have no 
further rights of complaint against the notified MVDDS transmitting 
antenna(s).
    (f) In the event of either an increase in the EPFD contour in any 
direction or a major modification as defined in Sec.  1.929 of this 
chapter, such as the addition of an antenna, to an MVDDS station, the 
procedures of paragraphs (d) and (e) of this section and rights of 
complaint begin anew. Exceptions to this are renewal, transfer of 
control, and assignment of license applications.
    (g) Interference complaints. The MVDDS licensee must satisfy all 
complaints of interference to DBS customers of record which are received 
during a one year period after commencement of operation of the 
transmitting facility. Specifically, the MVDDS licensee must correct 
interference caused to a DBS customer of record or cease operation if it 
is demonstrated that the DBS customer is receiving harmful interference 
from the MVDDS system or that the MVDDS signal exceeds the permitted 
EPFD level at the DBS customer location.



    Subpart Q_Service and Technical Rules for the 70/80/90 GHz Bands

Sec.  101.1501  Service areas.

    The 70/80/90 GHz bands are licensed on the basis of non-exclusive 
nationwide licenses. There is no limit to the number of non-exclusive 
nationwide licenses that may be granted for these bands, and these 
licenses will serve as a prerequisite for registering individual links.



Sec.  101.1505  Segmentation plan.

    (a) An entity may request any portion of the 71-76 GHz and 81-86 GHz 
bands, up to 5 gigahertz in each segment for a total of 10 gigahertz. 
Licensees are also permitted to register smaller segments.
    (b) The 92-95 GHz band is divided into three segments: 92.0-94.0 GHz 
and 94.1-95.0 GHz for non-government and government users, and 94.0-94.1 
GHz for Federal Government use. Pairing is allowed and segments may be 
aggregated without limit. The bands in paragraph (a) of this section can 
be included for a possible 12.9 gigahertz maximum aggregation. Licensees 
are also permitted to register smaller segments than provided here.

[70 FR 29998, May 25, 2005]

[[Page 757]]



Sec.  101.1507  Permissible operations.

    Licensees may use the 70 GHz, 80 GHz and 90 GHz bands for any point-
to-point, non-broadcast service. The segments may be unpaired or paired, 
but paring will be permitted only in a standardized manner (e.g., 71-
72.25 GHz may be paired only with 81-82.25 GHz, and so on). The segments 
may be aggregated without limit.



Sec.  101.1511  Regulatory status and eligibility.

    (a) Licensees are permitted to provide services on a non-common 
carrier and/or on a common carrier basis.
    (b) Licensees are subject to the requirements set forth in Sec.  
101.7.
    (c) Any entity, other than one precluded by Sec.  101.7, is eligible 
for authorization to provide service under this part. Authorization will 
be granted upon proper application filing and link coordination in 
accordance with the Commission's rules.



Sec.  101.1513  License term.

    The license term is ten years, beginning on the date of the initial 
authorization (nationwide license) grant. Registering links will not 
change the overall renewal period of the license.

[70 FR 29998, May 25, 2005]



Sec.  101.1523  Sharing and coordination among non-government licensees 
and between non-government and government services.

    (a) Registration of each link in the 71-76 GHz, 81-86 GHz, and 92-95 
GHz bands will be in the Universal Licensing System until the Wireless 
Telecommunications Bureau announces by public notice the implementation 
of a third-party database.
    (b) The licensee or applicant shall:
    (1) Complete coordination with Federal Government links according to 
the coordination standards and procedures adopted in Report and Order, 
FCC 03-248, and as further detailed in subsequent implementation public 
notices issued consistent with that order;
    (2) Provide an electronic copy of an interference analysis to the 
third-party database manager which demonstrates that the potential for 
harmful interference to or from all previously registered non-government 
links has been analyzed according to the standards of section 101.105 
and generally accepted good engineering practice, and that the proposed 
non-government link will neither cause harmful interference to, nor 
receive harmful interference from, any previously registered non-
government link; and
    (3) Provide upon request any information related to the interference 
analysis and the corresponding link. The third-party database managers 
shall receive and retain the interference analyses electronically and 
make them available to the public. Protection of individual links 
against harmful interference from other links shall be granted to first-
in-time registered links. Successful completion of coordination via the 
NTIA automated mechanism shall constitute successful non-Federal 
Government to Federal Government coordination for that individual link.
    (c) In addition, the following types of non-Federal Government links 
require the filing with the Commission an FCC Form 601 for each link for 
the purpose of coordination and registration, in addition to registering 
each link in the third-party database:
    (1) Facilities requiring the submission of an Environmental 
Assessment,
    (2) Facilities requiring international coordination, and
    (3) Operation in quiet zones.
    (d) The Commission believes the licensee is in the best position to 
determine the nature of its operations and whether those operations 
impact these settings, and is required to submit to a database manager, 
as part of the registration package, documentation that an FCC Form 601 
has been filed.

of the Nation's telecommunications resources during crises and 
emergencies is set forth in Executive Order 12472. The following parts 
of this chapter address specific responsibilities with respect to 
management of telecommunications resources and related procedures which 
bear upon provision, restoration and continuity of telecommunications 
services during crises and emergencies. In doing so, the chapter 
encompasses both national security and emergency preparedness 
activities, consistent with Executive Order 12472. This concept of 
national security and emergency preparedness telecommunications services 
(as defined in Sec.  201.2(g)) includes crises that do not necessarily 
entail serious degradation of, or serious threats to, national security. 
It therefore is a broader concept than the term ``national security 
emergency preparedness activities'' in Executive Order 12656, which 
concerns only national security emergencies, and preparedness activities 
necessarily related to such emergencies.



Sec.  201.1  Authority.

    (a) Authorities and responsibilities related to and bearing upon 
national security and emergency preparedness telecommunications matters 
are set forth in:
    (1) Section 706 of the Communications Act of 1934 (48 Stat. 1104, 47 
U.S.C. 606), as amended.

the Executive Agent, the NCS Committee of Principals and the Manager. 
The NCS Committee of Principals consists of representatives from those 
Federal departments, agencies or entities, designated by the President, 
which lease or own telecommunications facilities or services of 
significance to national security and emergency preparedness, and, to 
the extent permitted by law, other Executive entities which bear policy, 
regulatory or enforcement responsibilities of importance to national 
security and emergency preparedness telecommunications capabilities. The 
NCS is a confederative arrangement in which member Federal agencies 
participate with their owned and leased telecommunications assets to 
provide necessary communications services for the Federal Government, 
under all conditions, including nuclear war.
    (e) National Coordinating Center (NCC) refers to the joint industry-
government telecommunications entity established by the NCS pursuant to 
Executive Order 12472 to assist in the initiation, coordination, 
restoration and reconstitution of national security and emergency 
preparedness telecommunications services or facilities under all 
conditions of crisis or emergency.
    (f) National priorities means those essential actions and activities 
in which the government and the private sector must become engaged in 
the interests of national survival and recovery.
    (g) National security and emergency preparedness (NS/EP) 
telecommunications services, or NS/EP services, means those 
telecommunication services which are used to maintain a state of 
readiness or to respond to and manage any event or crisis (local, 
national, or international) which causes or could cause injury or harm 
to the population, damage to or loss of property, or degrades or 
threatens the NS/EP posture of the United States.
    (h) NS/EP treatment refers to the provisioning of a 
telecommunications service before others based on the provisioning 
priority level assigned by the Executive Office of the President.
    (i) National Telecommunications Management Structure (NTMS) means a 
survivable and enduring management structure which will support the 
exercise of the war power functions of the President under section 706 
of the Communications Act of 1934 (47 U.S.C. 606), as amended.
    (j) Private sector means those sectors of non-government entities 
that are users of telecommunications services.
    (k) Telecommunications means any transmission, emission, or 
reception of signs, signals, writing, images, graphics, and sounds or 
intelligence of any nature by wire, radio, optical, or other 
electromagnetic systems.
    (l) Telecommunications resources include telecommunications 
personnel, equipment, material, facilities, systems, and services, 
public and private, wheresoever located within the jurisdiction of the 
United States.
    (m) Wartime emergency means a crisis or event which permits the 
exercise of the war power functions of the President under section 706 
of the Communications Act of 1934 (47 U.S.C. 606), as amended.



Sec.  201.3  Policy.

    (a) The Federal Government is responsible for resources 
mobilization, including determination of the need for and the extent of 
mobilization necessary in all crises and emergencies, wartime and non-
wartime.
    (b) The President has limited non-wartime NS/EP telecommunications 
functions, and wartime NS/EP functions under the Communications Act of 
1934 (as amended), which have been delegated to Federal agencies under 
Executive Order 12472. Federal, State, and local governments share the 
responsibility for conservation of the Nation's telecommunications 
resources.
    (1) The achievement of survival and recovery during a crisis or 
emergency would establish an unavoidable interdependence between and 
among Federal, State, and local authorities; therefore, there should be 
no barriers between Federal and State levels of authorities and between 
State and local

[[Page 763]]

levels of authorities which would impede, obstruct, or otherwise hinder 
effective conservation and equitable allocation of telecommunications 
resources and services to the needs of the Nation.
    (2) The Federal Government will rely upon State governments and 
their telecommunications management organizations for management or 
control of intrastate carrier services and continuity of 
interconnectivity with interstate carriers to assure that national 
objectives and priorities are properly served. Applicable regulations of 
the Federal Communications Commission govern the extent of the 
allocation of responsibility between Federal and State authorities for 
the management of NS/EP intrastate carrier services and the 
interconnectivity of intrastate services for NS/EP telecommunications 
functions.
    (c) A system of telecommunications service priorities will be 
established which facilitates the provisioning and early restoration of 
services considered vital to national interests during those events or 
crises which warrant NS/EP treatment.
    (d) The President is authorized during, or in anticipation of, an 
emergency or major disaster (as defined in the Disaster Relief Act of 
19/4) to establish temporary telecommunications systems and to make such 
telecommunications available to State and local government officials and 
such other persons as deemed appropriate (42 U.S.C. 5185).
    (e) The President also is authorized, during war, when necessary in 
the interest of national defense and security, to direct or establish 
priorities for essential communications with any commercial or 
governmental carrier and to prevent obstruction of telecommunications. 
The President may also suspend or amend rules and regulations, close 
stations and facilities, and authorize U.S. government use and control 
of telecommunications resources with regard to:
    (1) Radio communications (during war, or Presidentially declared 
threat of war, public peril, disaster or national emergency or a need to 
preserve the neutrality of the U.S.) and
    (2) Wire communications (during war or threat of war).
    (f) During an attack on the United States by an aggressor nation, 
and in an immediate postattack period, all decisions regarding the use 
of telecommunications resources will be directed to the objective of 
national survival and recovery. In order to achieve this objective, 
postattack resources will be assigned to activities concerned with the 
maintenance and saving of lives, immediate military defense and 
response, and economic activities essential to continued economic 
survival and recovery.
    (g) The Director of the Office of Science and Technology Policy will 
serve as the central authority to control, coordinate, and direct the 
activities of the Nation's telecommunications facilities, systems, and 
services during periods of wartime emergency as determined under section 
706 of the Communications Act of 1934 (47 U.S.C. 606), as amended.
    (h) Telecommunications resources of the Federal Government will be 
employed, as required, to best serve the continuity of government and 
national interests.
    (i) Federal agencies will, in the development of emergency 
operational plans, minimize, to the extent feasible, dependence upon 
telecommunications services for continuity of essential operations.

Sec.  202.0  Objectives.

    (a) During, or in anticipation of, a non-wartime emergency or 
natural disaster, a telecommunications capacity must exist to provide 
temporary telecommunications service to State and local government 
officials and other persons deemed appropriate by the President.
    (b) In the event of a general war and attack upon the Nation, a 
national telecommunications capability must exist that will support 
telecommunications requirements with respect to national security, 
survival and recovery. The development of survivable telecommunications 
to support essential functions (including an emergency broadcasting 
system), and technical compatibility of signaling methods, transmission 
modes, switching facilities, and terminal devices to permit exchange of 
communications over the surviving media of all systems, government or 
commercial, are crucial elements of such a national capability. In 
addition, a survivable national telecommunications management structure 
is necessary to manage initiation, coordination and restoration of 
telecommunications services. The management structure must include the 
following:
    (1) Legal authority for telecommunications management.
    (2) A control mechanism to manage the initiation, coordination and 
restoration of telecommunications services.
    (3) Procedures to ensure timely damage assessment and allocation of 
residual resources and controlled restoration of services based on 
national policy/direction.
    (4) The capability to execute a telecommunications recovery plan 
based on national policy/guidance.
    (c) Notwithstanding any provision regarding NS/EP Planning and 
Execution, nothing in this part shall be deemed to affect the 
authorities or responsibilities of the Director of the Office of 
Management and Budget, or any Office or official thereof; or reassign 
any function assigned any agency under the Federal Property and 
Administrative Services Act of 1949, as amended, or under any other law, 
or any function vested by law in the Federal Communications Commission.



Sec.  202.1  Policies.

    (a) The telecommunications resources of the Nation will be available 
for government use during crises and emergencies, wartime and non-
wartime, and to satisfy the needs of the public welfare and safety.
    (b) The National Plan for Telecommunications Support in Non-Wartime 
Emergencies provides procedures for planning and using National 
telecommunications assets and resources in support of non-wartime 
emergencies, including those covered by the Disaster Relief Act of 1974, 
in Presidentially declared Emergencies and Major Disasters, 
Extraordinary Situations, and other emergencies.
    (c) An NS/EP Telecommunications Service Priority (TSP) System will 
provide procedures to authorize priority treatment for the provisioning 
and restoration of NS/EP telecommunications services for wartime and 
non-wartime emergencies.
    (d) In wartime emergencies, facilities management will remain 
decentralized to the extent feasible to assure continued flexibility of 
operational response to critical needs, subject to the management 
direction and overriding authority of those officials delegated to act 
for and with the consent of the central point of authority within the 
Federal Government.
    (1) Federally owned, leased, and/or operated telecommunications 
facilities, systems, and networks will be managed during such an 
emergency by the agency normally controlling the facility, system, or 
network except that all operations will be subject to the management 
direction and authority of the officials delegated overall management 
responsibility for Federal Government systems.
    (2) Facilities other than those of the Federal Government, with the 
exception of radio stations in the Aviation Services and certain classes 
of radio stations in the Maritime Services, will be managed by the 
authorized common carrier or other person owning and operating such 
facilities subject to Federal Communications Commission

[[Page 765]]

(FCC) guidance and direction or in accordance with State or local plans 
if not subject to FCC jurisdiction.
    (3) Radio stations in the Aviation Services and those aboard vessels 
in the Maritime Service will be subject to the control of the Secretary 
of Defense during a national emergency.
    (e) The Director of the Office of Science and Technology Policy is 
the single point of authority within the Federal Government for the 
wartime emergency functions under section 706 of the Communications Act 
(47 U.S.C. 606) with respect to the allocation and use of surviving 
resources in support of national objectives enunciated by the President. 
Authority may be redelegated as necessary and when it can be exercised 
within boundaries established by Presidential authority.
    (f) Radio frequency utilization during a wartime emergency will be 
in accordance with authorizations, assignments, and mobilization plans 
in existence at the onset of the emergency. Subject to the overriding 
control of the Director, OSTP, under the President's War Emergency 
Powers, spectrum management regarding the authorization and assignment 
of radio frequencies will be made by the National Telecommunications and 
Information Administration (NTLA) for the Federal Government, and the 
Director, OSTP, through the FCC, for all other entities subject to the 
Commission's jurisdiction. Radio stations are subject to closure if 
considered a threat to national security.
    (g) Section 706 of the Communications Act of 1934, as amended, 
confers authority to the President in the matter of suspension of all 
rules and regulations pertaining to the use and operation of 
telecommunications facilities, public or private during wartime 
emergencies.



Sec.  202.2  Criteria and guidance.

    NS/EP planning in government and industry with respect to effective 
conservation and use of surviving telecommunications resources in a 
disaster, emergency or postattack period must provide for orderly and 
uninhibited restoration of services by the carriers and authoritative 
control of services allocation which will assure that priority will be 
afforded the most critical needs of government and the private sector 
with respect to these objectives.
    (a) The preservation of the integrity of characteristics and 
capabilities of the Nation's telecommunications systems and networks 
during wartime or non-wartime emergencies is of the utmost importance. 
This can best be accomplished by centralized policy development, 
planning, and broad direction. Detailed operations management will 
remain decentralized in order to retain flexibility in the use of 
individual systems in responding to the needs of national security, 
survival and recovery. Each Federal agency responsible for 
telecommunications systems operations, and the carriers, are responsible 
for planning with respect to emergency operations. Guidance in this 
matter has been issued from a number of sources and contained in:
    (1) Annex C-XI (Telecommunications), Federal Emergency Plan D 
(Classified).
    (2) National Plan for Telecommunications Support in Non-wartime 
Emergencies.
    (3) The National Communications System Management Plan for Annex

C-XI (Telecommunications) Federal Emergency Plan D (Classified).
    (b) The continuity of essential communications services will be 
maintained through the use of controls and operational procedures to 
assure that priority is given to vital services. NS/EP 
telecommunications services entail policies, procedures and 
responsibilities as described in parts 211 and 213 of this chapter.
    (c) The Nation's telecommunications systems facilities are 
vulnerable to physical and radiological damage. Planning factors with 
respect to the resumption of services in a disaster or postattack period 
must consider the probable loss of facilities which formerly provided 
direct and/or alternate intercity services among surviving population 
centers. Since surviving areas and population centers would serve as the 
sources of support to crippled areas of the Nation, the resumption of 
services between and among surviving metropolitan areas will be a high 
priority with the carriers.

    (b) Non-wartime emergency functions. (1) The National Security 
Advisor shall:
    (i) Advise and assist the President in coordinating the development 
of policy, plans, programs and standards within the Federal Government 
for the identification, allocation and use of the Nation's 
telecommunications resources by the Federal Government, and by State and 
local governments, private industry and volunteer organizations, upon 
request, to the extent practicable and otherwise consistent with the 
law, during those crises or emergencies in which the exercise of the 
President's war power functions is not required or permitted by law.
    (ii) Provide policy oversight and direction of the activities of the 
NCS.
    (2) The Director of the Office of Science and Technology Policy 
shall:
    (i) Provide information, advice, guidance and assistance, as

estimates by participating agencies.
    (d) Performance of essential government and public services during a 
national emergency, as defined in section 706 of the Communications Act 
(47 U.S.C. 606), as amended, will require a means for communications 
between government and the private sector, communications essential to 
operations of elements of the national economy, and communications for 
national defense and civil defense purposes. The needs of the private 
sector and those of government should be properly coordinated to ensure 
that responses to each of these communities of interest, government and 
private sector, are appropriately balanced. For this reason, with regard 
to wartime emergency functions, the Director, Office of Science and 
Technology Policy (OSTP), has delegated the responsibility for the 
private sector to the Chairman, Federal Communications Commission (FCC), 
and responsibility for the needs of government to the Executive Agent, 
National Communications System (NCS). A parity of level of authority of 
these officials is established. They will coordinate and negotiate 
telecommunications conflicts with respect to the allocation and use of 
the Nation's telecommunications resources, reporting to the Director on

seq., March 29, 1978.

    Source: 43 FR 50431, Oct. 30, 1978, unless otherwise noted.



Sec.  211.0  Purpose.

    This part establishes policies and procedures under which government 
and private entities will be furnished restoration priorities to insure 
that leased intercity private line telecommunications services vital to 
the national interest will be maintained during the continuance of a war 
in which the United States engaged. It supersedes the Director of 
Telecommunications Management Order of January 15, 1967 (32 FR 791, 47 
CFR part 201), which is hereby canceled. To assure the effective ability 
to implement its provisions, and also in order that government and 
industry resources may be used effectively under all conditions ranging 
from national emergencies to international crises, including nuclear 
attack, a single set of rules and procedures is essential, and they must 
be applied on a day-to-day basis so that the priorities they establish 
can be implemented at once when the occasion arises. As provided for in 
part 18 of Executive Order 11490, as amended (3 CFR, 1966-1970 Comp., p. 
820), policies, plans, and procedures developed pursuant to the 
Executive order shall be in consonance with the plans and policies 
contained in this part.



Sec.  211.1  Authority.

    (a) Authority to direct priorities for the restoration of 
communications services in national emergencies is vested in the 
President, including authority conferred by section 103 of the National 
Security Act of 1947, as amended (50 U.S.C. 404), section 101 of the 
Defense Production Act of 1950, as amended (50 U.S.C. App. 2070), 
section 201 of the Federal Civil Defense Act of 1950, as amended (50 
U.S.C. App. 2281), section 1 of Reorganization Plan No. 1 of 1958, as 
amended (3 CFR, 1954-1958 Comp., p. 447), and section 606 of the Federal 
Communications Act of 1934, as amended. (47 U.S.C. 606).
    (b) Authority to develop plans policies, and procedures for the 
establishment of such restoration priorities has been delegated to the 
National Security Council, by Executive Orders 11051, 11490, and by the 
President's Memorandum of August 21, 1963 (28 FR 9413, 3 CFR part 858 
(1959-63 comp.)), all as

[[Page 771]]

amended by Executive Order 12046, (FR 43, 13349 et seq.).



Sec.  211.2  Definitions.

    The following definitions apply herein--
    (a) Communications common carrier or carrier means any person gaged 
in communications common carriage for hire, in intrastate, interstate, 
or international telecommunications.
    (b) Circuit means a carrier's specific designation of the overall 
facilities provided between, and including, terminals for furnishing 
service. When service involves network switching, circuit includes those 
circuits between subscriber premises and switching centers (access 
lines) and those between switching centers (trunks).
    (c) Station means transmitting or receiving equipment or combination 
transmitting and receiving equipment, at any location, or any premise, 
connected for private line service.
    (d) Private line service means leased intercity private line service 
provided by carriers for intercity domestic and international 
communications over integrated communications pathways, and includes 
interchange facilities, local channels, and station equipment which may 
be integral components of such communications service.
    (e) Restoration means the recommencement of service by patching, 
rerouting, substitution of component parts, and other means, as 
determined necessary by a carrier.
    (f) Government means Federal, foreign, State, county, municipal, and 
other local government agencies. Specific qualifications will be 
supplied whenever reference to a particular level of government is 
intended, e.g., Federal Government, State government. Foreign Government 
includes coalitions of governments secured by treaty, including NATO, 
SEATO, OAS, UN, and associations of governments or government agencies, 
including the Pan American Union, International Postal Union, and 
International Monetary Fund. Quasi-government includes eleemosynary 
relief organizations, such as the Red Cross organizations.
    (g) National Communications System (NCS) means that system 
established by the President's Memorandum of August 21, 1963, 
``Establishment of a National Communications System'' (28 FR 9413, 3 
CFR, 1959-1963 Comp., p. 858).
    (h) Executive Agent means the Executive Agent of the National 
Communications System.
    (i) Commission means the Federal Communications Commission.



Sec.  211.3  Scope and coverage.

    (a) The priority system and procedures established by this part are 
applicable to:
    (1) U.S. domestic leased intercity private line services, including 
private line switched network services;
    (2) U.S. international leased private line services to the point of 
foreign entry;
    (3) Foreign extensions of U.S. international leased private line 
services to the extent possible through agreement between U.S. carriers 
and foreign correspondents;
    (4) International leased private line services terminating in or 
transiting the United States;
    (5) Federal Government-owned and leased circuits.
    (b) The priority system and procedures established by this part are 
not applicable to operational circuits or order wires of the carriers 
needed for circuit reactivation and maintenance purposes, which shall 
have priority of restoration over all other circuits and shall be exempt 
from interruption for the purpose of restoring priority services.



Sec.  211.4  Policy.

    During the continuance of a war in which the United States is 
engaged and when the provisions of this part are invoked, all 
communications common carriers shall comply with the following 
principles insofar as possible:
    (a) Whenever necessary to maintain or restore a service having a 
designated priority, services having lower priority, lower subpriority, 
or no priority, will be interrupted in the reverse order of priority 
starting with nonpriority services.
    (b) When services are interrupted to restore priority services, 
carriers will endeavor if feasible to notify users of the reason for the 
preemption.

[[Page 772]]

    (c) When public correspondence circuits are needed to satisfy 
requirements for priority services, idle circuits will be selected 
first. A minimum number of public correspondence circuits shall at all 
times be kept available so as to provide for the transmission of 
precedence-type messages and calls.
    (d) Communications common carriers will not interrupt conversations 
having priority classification except insofar as necessary to restore 
services of higher priority.
    (e) It is recognized that as a practical matter in providing for the 
maintenance or restoration of a priority service or services operating 
within a multiple circuit-type facility (such as a carrier band, cable, 
or multiplex system), lower priority, lower subpriority, or nonpriority 
services on paralleled channels within a band or system may be restored 
concurrently with higher priority services. Such reactivation shall not, 
however, interfere with the expedited restoration of other priority 
services.
    (f) The Executive Agent is authorized to instruct the carriers on 
the percentage of government-switched network intermachine trunks to be 
restored to provide capacity for priority access line traffic.
    (g) The carriers are authorized to honor NCS-certified priorities 
from other authorized carriers for leased facilities.
    (h) The carriers are authorized to honor restoration priorities 
certified by the Executive Agent.
    (i) To ensure the effectiveness of the system of restoration 
priorities established by this part it is essential that rigorous 
standards be applied. Users are requested and directed to examine their 
private line service requirements in light of the criteria specified in 
this part and with regard to the availability of alternate 
communications facilities such as public correspondence message 
services, and Government-owned emergency communications systems.



Sec.  211.5  Priorities.

    There are hereby established four levels of restoration priority. 
Within each level, subpriorities may be established by the Executive 
Agent, with the concurrence of the National Security Council, for both 
government and nongovernment services. The subpriorities categories 
currently in use, which have been established by the Executive Agent 
will remain in effect until modified. Compatibility of subcategories 
applicable to government and nongovernment users is essential to achieve 
the objective of a single restoration priority system.
    (a) Priority 1. Priority 1 shall be the highest level of restoration 
priority, and shall be afforded only to Federal and Foreign Government 
private line services, and to Industrial/Commercial services which are 
designated for prearranged voluntary participation with the Federal 
Government in a national emergency. Circuit requirements in this level 
of priority shall be limited to those esential to national survival if 
nuclear attack occurs for:
    (1) Obtaining or disseminating critical intelligence concerning the 
attack, or immediately necessary to maintain the internal security of 
the United States;
    (2) Conducting diplomatic negotiations critical to the arresting or 
limiting of hostilities;
    (3) Executing military command and control functions essential to 
defense and retaliation;
    (4) Giving warning to the U.S. population;
    (5) Maintaining federal Government functions essential to national 
survival under nuclear attack conditions.
    (b) Priority 2. Priority 2 shall be the second highest level of 
restoration priority, and shall be afforded only to Federal and Foreign 
Government private line services, and to Industrial/Commercial services 
which are designated for prearranged voluntary participation with the 
Federal Government in a national emergency. Circuit requirements in this 
level shall be limited to those essential, at a time when nuclear attack 
threatens, to maintain an optimum defense posture and to give civil 
alert to the U.S. population. These are circuit requirements whose 
unavailability would present serious dangers:
    (1) Reducing significantly the preparedness of U.S. defense and 
retalitory forces;

[[Page 773]]

    (2) Affecting adversely the ability of the United States to conduct 
critical preattack diplomatic negotiations to reduce or limit the threat 
of war;
    (3) Interfering with the effectual direction of the U.S. population 
in the interest of civil defense and survival;
    (4) Weakening U.S. capability to accomplish critical national 
internal security functions;
    (5) Inhibiting the provision of essential Federal Government 
functions necessary to meet a preattack situation.
    (c) Priority 3. Priority 3 shall be the third highest level of 
restoration priority and shall be afforded to government, quais-
government, and Industrial/Commercial private line services: Provided, 
however, That Priority 3 will be afforded circuits serving Industrial/
Commercial, State, county, municipal, and quasi-state and local 
government agencies only where, during an emergency, at least one 
station in the circuit (or in connected circuits if switched service is 
involved) will be manned continually, or where such circuits are 
automated and will be under constant surveillance from a remote 
location. Circuit requirements in this level shall be limited to those 
necessary for U.S. military defense and diplomacy, for law and order, 
and for national health and safety in a national emergency involving 
heightened possibility of hostilities. These are curcuit requirements 
needed to:
    (1) Insure performance of critical logistic functions, public 
utility services, and administrative-military support functions;
    (2) Inform key diplomatic posts of the situation and of U.S. 
intentions;
    (3) Secure and disseminate urgent intelligence;
    (4) Distribute essential food and other supplies critical to health;
    (5) Provide for critical damage control functions;
    (6) Provide for hospitalization;
    (7) Continue critical Government functions;
    (8) Provide transportation for the foregoing activities.
    (d) Priority 4. Priority shall be the fourth highest restoration 
priority and shall be afforded to government, quasi-government, and 
Industrial/Commercial private line services: Provided, however, That 
Priority 4 will be afforded circuits serving Industrial/Commercial, 
State, county, municipal, and quasi-state and local government agencies 
only where, during an emergency, at least one station in the circuit (or 
in connected circuits if switched service is involved) will be manned 
continually, or where such circuits are automated and will be under 
constant surveillance from a remote location. Circuit requirements in 
this level shall be limited to those necessary for the maintenance of 
the public welfare and the national economy in a situation short of 
nuclear attack, or during reconstitution after attack. These include 
circuit requirements needed to continue the more important financial, 
economic, health, and safety activities of the Nation.



Sec.  211.6  Submission and processing of restoration priority requests.

    (a) Except as otherwise provided below, all requests for restoration 
priority assignments will be submitted to the Executive Agent in the 
format prescribed by him for processing and certification.
    (b) Priority 3 and 4 applications from county and municipal 
governments, quasi-state and local government agencies and private 
entities shall be forwarded to the Federal Communications Commission for 
its approval and for certification to the carriers. These submissions 
will be in the form prescribed by the Commission.
    (c) Industrial/Commercial entities designated for prearranged 
voluntary participation with the Federal Government in a national 
emergency should submit separate applications to the Commission when 
requesting the assignment of priorities in category 1 or 2. Such 
assignments will require the approval of the National Security Council 
in order to continue to be effective during a war emergency. In all 
cases the justification for restoration priorities will contain a 
validation statement from the Government agency with whom participation 
is prearranged.
    (d) Requests for restoration priority assignments made by Foreign 
Government agencies, except for NATO, NATO national military authority, 
and such

[[Page 774]]

other requests as the Executive Agent may be designated, will be 
submitted to the Department of State for initial evaluation and review. 
The Department will forward to the Executive Agent for processing and 
approval such of these requests as it finds acceptable.
    (e) Requests for restoration priority assignments made by NATO, NATO 
national military authority, and such other requests as the Executive 
Agent may designate, will be forwarded through established Allied Long 
Lines Agency (ALLA) channels to the Secretary of Defense. The Secretary 
will forward to the Executive Agent for processing and approval such of 
these requests as he finds acceptable pursuant to approved NATO/U.S. 
procedures.
    (f) Requests for temporary upgrading of restoration priority 
assignments occasioned by special critical conditions, including natural 
disasters, heightened diplomatic and political tenseness, and tracking 
and control of manned space operations, may be submitted to the 
Executive Agent together with such information as he may require for 
expedited processing decision.
    (g) All assignments, denials and changes of restoration priorities 
and subpriorities are subject to review and modification by the National 
Security Council.
    (h) When requesting service from the carriers the user must include 
the certified restoration priority on the service authorization.



Sec.  211.7  Obligation of carriers.

    (a) During the continuance of a war in which the United States is 
engaged, and when the provisions of this part are invoked, all carriers 
shall accord restoration priority assignments certified pursuant to this 
part priority over all other circuits.
    (b) To promote the national interest and defense preparedness, 
carriers shall:
    (1) Maintain such records of restoration priority assignments 
certified pursuant to this part as may be necessary to enable prompt 
implementation;
    (2) Enter into agreements, to the extent possible, with their 
foreign correspondents to effect restoration of the foreign portion of 
leased international services in accordance with this part;
    (3) Notify the Executive Agent of foreign correspondent procedures 
affecting Federal Government services that are not reasonably consistent 
with the priority requirements of this part.

    Source: 43 FR 50434, Oct. 30, 1978, unless otherwise noted.



Sec.  213.0  Authority.

    (a) The voice and message precedence procedures for departments and 
agencies of the Federal Government prescribed by this part are 
prescribed pursuant to Executive Order No. 12046 (43 FR 13349 et seq.) 
and the President's memorandum of August 21, 1963, which established the 
National Communications System (28 FR 9413; 3 CFR, 1959-1963 Comp., p. 
858).
    (b) The procedures applicable to communications common carriers and 
non-Federal Government users prescribed by this part are prescribed by 
authority conferred upon the President by subsection 606(a) of the 
Communications Act of 1934, as amended, and delegated to the National 
Security Council by Executive Order 12046. That authority under section 
606(a) may be exercised only during the continuance of a war in which 
the United States is engaged.



Sec.  213.1  Background and purpose.

    (a) The National Security Council and the Federal Communications 
Commission have agreed upon a precedence system for the expeditious 
handling of messages and calls transmitted over Government and public 
correspondence facilities in all types of situations from peacetime to 
massive nuclear attack. Effectuation of that system requires that the 
Director issue a circular and

[[Page 776]]

that the Commission concurrently issue an order prescribing the 
standards, procedures, policies, and regulations that together, 
constitute this single integrated precedence system.
    (b) In conformity with that agreement the National Security Council 
is issuing this circular the purpose of which is to prescribe, on behalf 
of the President, that part of those standards, procedures, policies, 
and regulations which are within the cognizance of the NSC. No 
significance should be attached to the fact that slightly different 
terms are used in their circular from those used in the companion order 
of the FCC. Those differences result from differences in terms in the 
basic legal authorities of the director and the Commission rather than 
from an intent to denote a distinction in purpose or effect.



Sec.  213.2  Scope.

    The precedence system contained herein is applicable to:
    (a) Users of Government service facilities, whether owned or leased.
    (b) Users of public correspondence service facilities of the 
communication common carriers, to U.S. domestic and international 
communication common carriers, and to the extent possible by agreement 
between the latter and their foreign correspondents.



Sec.  213.3  Cancellation.

    This circular cancels:
    (a) Attachments A and B to Annex 3 of DMO 3000.1, dated November 8, 
1963 (28 FR 12273).
    (b) That portion of the memorandum of the Special Assistant to the 
President for Telecommunications, dated August 27, 1964, pertaining to 
message precedences.



Sec.  213.4  Definitions.

    As used herein:
    (a) Public correspondence services means those services offered to 
the general public for communications between all points served by a 
carrier or by interconnected carriers on a nonexclusive message by 
message or call by call basis, as differentiated from leased private 
line services.
    (b) The term precedence means the order in which messages and calls 
are processed. Transmission of information and call completion is 
therefore to be accomplished in the order required by the precedence 
designator. Any such properly categorized communications precede 
noncategorized communications.
    (c) The term Government where used alone means Federal, foreign, 
State, county, or municipal government agencies. Specific reference will 
be made whenever it is intended to apply to less than the whole, e.g., 
State Government, Federal Government, etc.
    (d) The term Foreign Government includes those foreign diplomatic 
and consular establishments and those coalitions or associations of 
governments such as NATO, SEATO, OAS, UN, and associations of 
governments or governmental agencies such as Pan American Union, 
International Postal Union, International Monetary Fund, and similar 
organizations.
    (e) The term message means a written or other form of record 
communication prepared for transmission and delivery at the destination.
    (f) The term call means a request from a user for a connection to 
another station whether for telephone or record communication.



Sec.  213.5  Precedence designators.

    (a) The following precedence designators are available for 
Government and public correspondence users:

------------------------------------------------------------------------
                                                  Domestic public
            Federal Government                   correspondence and
                                           international telephone calls
------------------------------------------------------------------------
Flash....................................  Flash emergency.
Immediate................................  Immediate emergency.
Priority.................................  Priority emergency.
Routine..................................  (No domestic equivalent.)
------------------------------------------------------------------------

    (b) Government and non-Government users of public correspondence 
services will handle their international messages in accordance with 
current ITU Telegraph Regulations. Government users should note that, 
generally, the only precedence designator available for their use for 
international messages sent over public correspondence circuits if Etat 
Priorite. The ITU Regulations do not contain precedence designators 
which equate to Flash, Immediate, or Priority. Accordingly, Government 
messages whether Flash, Immediate, or Priority precedence when

[[Page 777]]

sent over international public correspondence circuits will be handled 
as Etat Priorite messages. Thus, Priority messages will receive the same 
treatment in transmission and processing as Immediate or Flash messages. 
Conversely, Etat Priorite messages received in the United States shall 
be transmitted and processed in the order of receipt, to the extent 
possible. The precedence designator available for non-Government users 
of public correspondence services is Urgent. The Urgent designator is 
limited for use only during wartime conditions, as declared pursuant to 
section 606 of the Communications Act of 1934.
    (c) Domestic and International U.S. common carriers, insofar as 
practicable by agreement with their foreign correspondents, shall 
endeavor to arrange the proper level of precedence handling of 
international messages and calls originating, terminating in, or 
transiting the United States: Provided, however, That insofar as 
international messages are concerned the level of precedence shall be 
consistent with the International Telecommunication Conventions and 
regulations thereunder.
    (d) The Government designators shall be used throughout the Federal 
Government. All messages and telephone calls sent via public 
correspondence services shall use domestic or international public 
correspondence des ignators as appropriate. Thus, the responsibility is 
on Government and public correspondence users to recognize and use the 
appropriate designators when using public correspondence services.
    (e) On international telephone calls the carrier's operator will 
convert to the appropriate international designator.



Sec.  213.6  Criteria.

    (a) Flash, Flash Emergency. (1) This is the highest order of 
precedence and shall be strictly limited to Federal and Foreign 
Government agencies.
    (2) Flash, or Flash Emergency telephone calls or messages shall be 
handled in the order received and ahead of all calls or messages except 
as indicated for international messages in ITU Regulations. When 
necessary to obtain a circuit for a Flash, or Flash Emergency call any 
call in progress of a lesser precedence will be interrupted, if 
feasible. Any message of a lesser precedence in the process of 
transmission will be halted, if feasible, to clear the channel for the 
Flash or Flash Emergency transmission. Flash or Flash Emergency 
precedence shall be reserved for calls and messages having an immediate 
bearing on:
    (i) Command and control of military forces essential to defense and 
retaliation.
    (ii) Critical intelligence essential to national survival.
    (iii) Conduct of diplomatic negotiations critical to the arresting 
or limiting of hostilities.
    (iv) Dissemination of critical civil alert information essential to 
national survival.
    (v) Continuity of Federal governmental functions essential to 
national survival.
    (vi) Fulfillment of critical U.S. internal security functions 
essential to national survival.
    (vii) Catastrophic events of national or international significance, 
such as Presidential Action Notices essential to national survival 
during attack or preattack conditions.
    (b) Immediate, Immediate Emergency, Urgent. Immediate, Immediate 
Emergency, or Urgent telephone calls or messages shall be handled as 
fast as possible and ahead of all other calls or messages except those 
having a higher precedence. Any message or call of a lower precedence in 
the process of transmission will be halted, if feasible, to clear the 
channel for this transmission. It will be reserved generally for calls 
or messages pertaining to:
    (1) Situations which gravely affect the security of national and 
allied forces.
    (2) Reconstitution of forces in a post attack period.
    (3) Intelligence essential to national security.
    (4) Conduct of diplomatic negotiations to reduce or limit the threat 
of war.
    (5) Implementation of Federal Government actions essential to 
national survival.

[[Page 778]]

    (6) Situations which gravely affect the internal security of the 
United States.
    (7) Civil defense actions concerning direction of our population and 
its survival.
    (8) Disasters or events of extensive seriousness having an immediate 
and detrimental effect on the welfare of the population.
    (9) Vital information having an immediate effect on aircraft, 
spacecraft, or missile operations.
    (c) Priority, Priority Emergency, Urgent. Priority, Priority 
Emergency, or Urgent messages and calls shall take precedence over 
messages or calls designated Routine, or in the case of common carriers, 
over all nonprecedence traffic. Priority, Priority Emergency, or Urgent 
precedence is generally reserved for calls or messages which require 
expeditious action. Examples are calls or messages pertaining to:
    (1) Information on locations where attack is impending or where fire 
or air support will soon be placed.
    (2) Air-ground integrated operations.
    (3) Important intelligence.
    (4) Important diplomatic information.
    (5) Important information concerning the launch, operation, or 
recovery of spacecraft or missiles.
    (6) Movement of naval, air, and ground forces.
    (7) Coordination between governmental agencies concerning the 
performance of emergency preparedness functions.
    (8) Major civil aircraft accidents.
    (9) Maintaining the public health, safety, and the welfare of our 
population.
    (10) Critical logistic functions, provisions of critical public 
utility services, and administrative military support functions.
    (11) Distributing essential food and supplies critical to health.
    (12) Accomplishing tasks necessary to insure critical damage control 
functions.
    (13) Preparations for adequate hospitalization.
    (14) Continuity of critical Government functions.
    (15) Arranging minimum transportation for accomplishing the 
aforesaid functions.
    (16) Continuing or reestablishing our more important financial, 
economic, health, and safety activities. Producing, procuring, and 
distributing food materials and supplies which are considered necessary 
to the immediate support of a war effort, the national defense, or for 
expediting the means of meeting the effects of natural disas ters.
    (17) Prompt delivery of information by press representatives to news 
media organizations and newspapers covering news of national or 
widespread disasters.
    (d) Routine; no domestic equivalent. Routine precedence designation 
applies to those normal day-to-day communications which require rapid 
transmission by telephone or message, but do not require urgent or 
preferential handling.



Sec.  213.7  Policies.

    (a) Calls and messages in each precedence classification above shall 
have no precedence over others within the same classification, except 
where, within the same classification, they cannot be handled 
simultaneously. Then, they shall be handled in the order of their 
receipt.
    (b) Individuals whose requirements qualify them to use the 
precedence system share the responsibility for insuring its 
effectiveness. Users must familiarize themselves with the purposes to be 
served by the use of each precedence designator. It must be remembered 
that the entire system will operate successfully only if the use of the 
precedence designator is limited strictly to the intended purposes. Each 
user must consider whether each message or call requires any special 
precedence and exercise care not to specify a higher precedence than 
circumstances require.
    (c) For public correspondence message services, the domestic or 
international precedence designators shall be shown in full by the 
sender as the first word preceding the name of the addressee.
    (d) For public correspondence call services, the user should first 
attempt to complete the call in the normal

[[Page 779]]

manner. In the event the user is unable to complete the call and the 
type of communication falls within one of the precedence categories 
listed herein the call should be filed with an operator for completion 
and the user must specify the required precedence handling by stating 
that this is a Flash Emergency, Immediate Emergency, or Priority 
Emergency call, whichever the case may be.
    (e) Any apparent misuse of precedence indicators by non-Federal 
Government activities brought to the attention of the communication 
common carriers shall be referred to the FCC on and after-the-fact 
basis.
    (f) Any apparent misuse by Federal Government activities brought to 
the attention of the communication common carriers shall be referred to 
the Executive Agent, National Communications System. The Executive Agent 
will refer any matter which cannot be resolved with the cognizant 
Government activity to the National Security Council, for decision.
    (g) It is essential to provide public message and call capability 
for the transmission of military, governmental, and essential non-
Government precedence messages and calls. Private line services for 
military, governmental, and other essential users are protected under a 
Priority System for Intercity Private Line Services promulgated by the 
FCC (FCC Order 67-51) and the National Security Council. However, during 
national emergencies, military, governmental, and other essential users 
will have additional requirements for prompt completion of precedence 
traffic over public correspondence communication common carrier 
facilities. Therefore, notwithstanding the provisions of the above-
described Priority System for Intercity Private Line Services, 
communication common carriers shall have available a minimum number of 
public correspondence circuits at all times so as to provide for the 
transmission of precedence type messages and calls. Normally, the 
communication common carriers shall use their judgment in determining 
this number of circuits required for public correspondence precedence 
traffic. However, the authority is reserved to the National Security 
Council or the Federal Communications Commission, as appropriate to the 
time and situation, to revise the decisions of the carriers respecting 
the allocation of circuits, and to resolve any questions which are 
referred to them by the carriers or the users.



Sec.  213.8  Implementation.

    Federal departments and agencies are authorized to issue such 
additional orders as are necessary to effect implementation of this 
circular.

215.2 Assignment of responsibilities.

    Authority: 84 Stat. 2083, and E.O. 12472, April 3, 1984 (49 FR 13471 
et seq.).

    Source: 55 FR 51063, Dec. 11, 1990, unless otherwise noted.



Sec.  215.0  Purpose and authority.

    The purpose of this part is to designate a focal point within the 
Federal Government for electromagnetic pulse (EMP) information 
concerning telecommunications. It is issued pursuant to the authority of 
Reorganization Plan No. 1 of 1977, 42 FR 56101, 91 Stat. 1633, as 
amended (5 U.S.C. appendix), Executive Order 12472, (49 FR 13471; 3 CFR, 
1984 Comp., p. 193), ``Assignment of National Security and Emergency 
Preparedness Telecommunications, April 3, 1984 and Executive Order 
12046, 43 FR 13349, ``Relating to the Transfer of Telecommunications 
Functions,'' May 27, 1978, as amended by Executive Order 12472.



Sec.  215.1  Background.

    (a) The nuclear electromagnetic pulse (EMP) is part of the complex 
environment produced by nuclear explosions. It consists of transient 
voltages and currents which can cause malfunctioning and serious damage 
to electrical and electronic equipment.
    (b) The Defense Nuclear Agency (DNA) is the overall technical 
coordinator for the Army, Navy, Air Force, and DOE laboratories on 
matters concerning nuclear weapons, nuclear weapons effects, and nuclear 
weapons testing. It acts as the focal point between the service 
laboratories and other agencies. The National Communications System 
(NCS), with the Defense Communications Agency (DCA), maintains a data 
base for telecommunications. DCA also provides the primary capability 
for the NCS to conduct telecommunications survivability studies for 
civil and military departments and agencies.
    (c) In order to disseminate among affected Federal agencies 
information concerning the telecommunications effects of EMP and 
available protective measures, and in order to avoid duplication of 
research efforts, it is desirable to designate a focal point within the 
Federal Government for telecommunications EMP matters.



Sec.  215.2  Assignment of responsibilities.

    The Executive Agent, NCS, shall be the focal point within the 
Federal Government for all EMP technical data and studies concerning 
telecommunications. It shall provide such data and the results of such 
studies to all appropriate agencies requesting them. It shall coordinate 
and approve EMP telecommunications tests and studies, and shall keep the 
National Security Advisor informed regarding such tests and studies 
being conducted and planned.

    B. Model NLP MOA

    Director, Office of Management and Budget.

    Dated: November 17, 1987.

 Appendix B--Model National Level NSEP Telecommunications Program (NLP) 
                  Funding Memorandum of Agreement (MOA)

    1. Purpose: This Memorandum of Agreement (MOA) defines the 
relationship between and responsibilities of the (name of NCS member 
organization) and the Office of the Manager, NCS (OMNCS), with respect 
to the financial management of national level national security 
emergency preparedness (NSEP) telecommunications programs approved by 
the Executive Office of the President (EOP) in the National Level NSEP 
Telecommunications Program (NLP).
    2. Scope: This MOA is limited to the implementation and recurring 
costs of approved national level NSEP telecommunications programs, 
including termination liability costs, if applicable. Development costs 
will be funded by the Department of Defense.
    3. Background: In April 1984, Executive Order No. 12472, 
``Assignment of National Security and Emergency Preparedness 
Telecommunications Functions,'' established a framework for the funding 
of NSEP telecommunications initiatives by the NCS, providing for:
    a. The prescription, by the Office of Management and Budget (OMB) in 
consultation with the National Security Council (NSC) and the NCS, of 
general guidelines and procedures for reviewing the financing of the NCS 
within the budgetary process, and for the preparation of budget 
estimates by participating agencies.
    b. The determination, by the NSC, the Office of Science and 
Technology Policy (OSTP), and OMB in consultation with the Executive 
Agent, NCS, and the NCS Committee of Principals (COP), of what 
constitutes NSEP telecommunications requirements, and
    c. The determination, by Federal departments and agencies, of their 
NSEP telecommunications requirements and the provision, after 
consultation with the Office of Management and Budget (OMB), of 
resources to support their respective requirements for NSEP 
telecommunications.
    To implement the provisions of Executive Order No. 12472, the 
President directed in National Security Decision Directive (NSDD) 201, 
that ``implementation and recurring costs for national level NSEP 
telecommunications programs (i.e., those which benefit multiple Federal 
departments, agencies or entities) shall be shared on a pro rata basis 
determined by each organization's share of NSEP telecommunications 
requirements.'' The Director, OMB, subsequently instructed the NCS 
member organizations to work with the Manager, NCS, to develop the 
necessary agreements for the payment of member funds to the Office of 
the Manager, NCS (OMNCS).
    4.0 Responsibilities
    4.1 The Office of the Manager, NCS, shall:
    a. Serve as the Office of Primary Responsibility for the financial 
and program management of approved national level NSEP 
telecommunications programs.

[[Page 791]]

    b. Upon approval of national level NSEP telecommunications programs 
and receipt of funding guidance from the EOP, prepare an Interagency 
Funding Agreement necessary to effect the payment of (name of NCS member 
organization) funds to the Manager, NCS. This agreement shall be 
executed by August 31 each year.
    c. Prepare and provide vouchers for transfers between appropriations 
and/or funds (Standard Form 1080) for (name of NCS member organization)
    d. Provide technical, programmatic, and financial management support 
for individual national level NSEP telecommunications programs, 
including the maintenance of financial records and accounting system and 
the update of program plans.
    e. Report quarterly to the NCS COP on the programmatic and financial 
status of approved national level NSEP telecommunications programs.
    f. Advise the (name of NCS member organization) of any significant 
programmatic or financial adjustments/modifications.
    4.2 The (name of NCS member organization) will:
    a. Incorporate its respective funding share of approved national 
level NSEP telecommunications programs in its annual budget submission.
    b. Execute with the Manager, NCS, by August 31 each year the 
Interagency Funding Agreement required for the transfer, payment and/or 
reimbursement of funds for the NLP.
    c. Upon receipt of appropriations (or Continuing Resolution(s)) for 
each applicable fiscal year and subject to OMB apportionment of those 
funds, effect the payment of funds to the Manager, NCS, in accordance 
with Standard Form 1080.
    5.0 Implementation: This MOA is effective upon the date of the 
latest signature. This MOA is subject to periodic review and update as 
circumstances warrant and will terminate upon the mutual agreement of 
the parties. Compliance with this MOA is subject to the authorization 
and appropriation of funds by the Congress.

Change 1, May 30, 1978; are hereby superseded by, and cancelled under 
the authority of this directive on its effective date.
    6. Definitions. See appendix.
    7. Scope of the NSEP TSP System.
    a. Domestic NSEP Services. The NSEP TSP System and procedures 
established in 47 CFR part 64 and in this directive authorize priority 
treatment to the following domestic telecommunication services 
(including portions of U.S. international telecommunication services 
provided by U.S. vendors) for which provisioning or restoration priority 
levels are requested, assigned, and approved in accordance with this 
directive and any implementing manuals:
    (1) Common carrier services which are:
    (a) Interstate or foreign telecommunication services.
    (b) Intrastate telecommunication services inseparable from 
interstate or foreign telecommunications services, and intrastate 
telecommunication services to which priority levels are assigned 
pursuant to paragraph 13 of this directive.
    (Note: Initially, the NSEP TSP System's applicability to public 
switched services is limited to (a) provisioning of such services (e.g., 
business, centrex, cellular, foreign exchange, Wide Area Telephone 
Service (WATS) and other services that the selected vendor is able to 
provision), and (b) restoration of services that the selected vendor is 
able to restore.)
    (2) Services which are provided by government and/or non-common 
carriers and are interconnected to common carrier services assigned a 
priority level pursuant to paragraph 13 of this directive.
    b. Control Services and Orderwires. The NSEP TSP System and 
procedures implemented in this directive are not applicable to authorize 
priority treatment to control services or orderwires owned by a service 
vendor and needed for provisioning, restoration, or maintenance of other 
services owned by that vendor. Such control services and orderwires 
shall have priority of provisioning and restoration over all other 
telecommunication services (including NSEP services) and shall be exempt 
from preemption. However, the NSEP TSP System and procedures implemented 
in this directive are applicable to control services or orderwires 
leased by a service vendor or user from another service vendor.
    c. Other Services. The NSEP TSP System may apply, at the discretion 
of and upon special arrangements by the entities involved, to authorize 
priority treatment to the following telecommunication services:
    (1) Government or non-common carrier services which are not 
connected to common carrier provided services assigned a priority level 
pursuant to paragraph 13 of this directive.
    (2) Portions of U.S. international services which are provided by 
foreign correspondents. (Subject to pertinent law, including references 
4a, 4c, and 4f, U.S. telecommunication service vendors are encouraged to 
ensure that relevant operating arrangements are consistent to the 
maximum extent practicable with the NSEP TSP System. If such agreements 
do not exist, U.S. telecommunication service vendors should handle 
service provisioning and/or restoration in accordance with any system 
acceptable to their foreign correspondents which allows provisioning and 
restoration in the manner most comparable to the procedures established 
in this directive.) In addition, the U.S. government, acting through the 
Department of State, may enter into the following types of agreements to 
ensure that priority provisioning and restoration procedures consistent 
with those governing domestic services within the NSEP TSP System are in 
place: (a) Bilateral agreements for reciprocal priority treatment for 
critical foreign government telecommunication services in the U.S., and 
(b) multilateral agreements within such international telecommunication 
organizations as the North Atlantic Treaty Organization's Allied Long 
Lines Agency or Civil Communications Planning Committee, which have or 
are conducive to having a provisioning and restoration priority system.
    d. Subpriority and Precedence Systems. Service users may implement 
subpriority and/or precedence systems that are consistent, and do not 
conflict with, the NSEP TSP System.
    8. Policy. The NSEP TSP System is the regulatory, administrative, 
and operational system authorizing and providing for priority treatment 
(i.e., provisioning, and restoration) of NSEP telecommunication services

[[Page 793]]

(see definition in appendix). As such, it establishes the framework for 
NSEP telecommunication service vendors to provision, restore, or 
otherwise act on a priority basis to ensure effective NSEP 
telecommunication services. The NSEP TSP System allows the assignment of 
priority levels to any NSEP service across three time periods, or stress 
conditions: Peacetime/Crisis/Mobilization, Attack/War, and Post-Attack/
Recovery. All requests for priority level assignments will be processed 
through the Manager, NCS. Although priority levels normally will be 
assigned by the Manager, NCS, and retained by service vendors, only for 
the current time period, they may also be preassigned for the other two 
time periods at the request of service users who are able to identify 
and justify, in advance, their wartime or post-attack NSEP 
telecommunication requirements. Absent such preassigned priority levels 
for the Attack/War and Post-Attack/Recovery periods, priority level 
assignments for the Peacetime/Crisis/Mobilization period will remain in 
effect. At all times, priority level assignments will be subject to 
revision by the Federal Communications Commission (FCC); or, on an 
interim basis, the Director, Office of Science and Technology Policy 
(OSTP); and the Manager, NCS, based upon changing NSEP needs. No other 
system of telecommunication service priorities which conflicts with the 
NSEP TSP System is authorized.
    9. Legal Basis for the NSEP TSP System. The laws and regulations 
authorizing the NSEP TSP System are those cited above in paragraphs 3 
and 4.
    a. Communications Act. Sections 1, 4(i), and 201 thru 205 of the 
Communications Act of 1934 (47 U.S.C., 151, 154(i), and 201 thru 205) 
grant to the FCC the authority over assignment and approval of 
priorities for provisioning and restoration of common carrier-provided 
telecommunication services. Under section 706 of the Communications Act, 
this authority may be superseded, and expanded to include privately 
owned telecommunication services, by the war emergency powers of the 
President of the United States.
    b. Executive Order No. 12472. In Executive Order No. 12472, the 
President tasked the NCS to assist the Director, OSTP, in the exercise 
of the President's war emergency powers. Executive Order No. 12472 also 
directs the Manager, NCS, to assist the Director, OSTP, in executing 
those functions by developing plans and procedures for the management, 
allocation and use (including the establishment of priorities and 
preferences) of federally owned or leased telecommunication assets.
    c. Federal Rules. The FCC and Executive Office of the President 
(EOP) have used their respective authorizations to develop and establish 
the NSEP TSP System as the one uniform system of priorities for the 
provisioning and restoration of NSEP telecommunication services, both 
before and after invocation of the section 706 Presidential war 
emergency powers. The Federal rules governing the NSEP TSP System have 
been promulgated by the FCC and OSTP (on behalf of the EOP) in title 47 
of the Code of Federal Regulations. In those rules, the FCC has 
requested the EOP to administer the NSEP TSP System before the 
invocation of section 706 of the Communications Act, Presidential war 
emergency powers. In this directive, the EOP assigns to the Manager, 
NCS, both this administrative authority to administer the NSEP TSP 
System before, and the President's statutory authority to administer the 
NSEP TSP System after, the invocation of the section 706 Presidential 
war emergency powers.
    d. Defense Production Act. The Defense Production Act of 1950 
authorizes the President to require the priority performance of 
contracts and orders necessary to promote national defense. It also 
authorizes the President to allocate materials and facilities as 
necessary to promote national defense. Pursuant to the Defense 
Production Act, regulations promulgated by the Department of Commerce in 
the Defense Priorities and Allocations System (DPAS) permit the 
assignment of ``priority ratings'' to equipment associated with NSEP 
telecommunication services warranting priority treatment, if they 
support authorized programs under Schedule I of the DPAS.
    e. Contracts. NSEP telecommunication service users may also employ 
contractual mechanisms to obtain the priority provisioning or 
restoration of service, including customer premises equipment and 
wiring. However, any such contractual arrangements must be consistent 
with NSEP TSP System rules and regulations, including any priority order 
of provisioning and restoration assigned in accordance with the NSEP TSP 
System.
    10. Responsibilities.
    a. Federal Communications Commission. As authorized by the 
Communications Act the FCC will:
    (1) Provide regulatory oversight of implementation of the NSEP TSP 
System.
    (2) Enforce NSEP TSP System rules and regulations which are 
contained in 47, CFR, part 64.
    (3) Act as final authority for approval, revision, or disapproval of 
priority actions by the Manager, NCS, and adjudicate disputes regarding 
either priority actions or denials of requests for priority actions by 
the Manager, NCS, until superseded by the President's war emergency 
powers under section 706 of the Communications Act.
    (4) Function (on a discretionary basis) as a sponsoring Federal 
organization. (See paragraph 10d below.)

[[Page 794]]

    b. Director, Office of Science and Technology Policy. The Director, 
OSTP, EOP, will:
    (1) During exercise of the President's war emergency powers under 
section 706 of the Communications Act, act as the final approval 
authority for priority actions or denials of requests for priority 
actions, adjudicating any disputes.
    (2) Provide oversight of Executive branch activities associated with 
the NSEP TSP System, including assignment of priority levels for 
telecommunications service provisioning and restoration across all time 
periods.
    (3) Function (on a discretionary basis) as a sponsoring Federal 
organization. (See paragraph 10d below.)
    c. Manager, NCS. The Manager, NCS, will:
    (1) Implement the NSEP TSP System under the oversight of the FCC and 
Director, OSTP, in consultation with the NCS Committee of Principals.
    (2) Administer the NSEP TSP System, which includes:
    (a) Receiving, processing, and evaluating requests for priority 
actions from service users, or sponsoring Federal government 
organizations on behalf of service users (e.g., Departments of State or

Agency on behalf of state and local governments, and any Federal 
organization on behalf of private industry entities). Action on such 
requests will be completed within 30 days of receipt.
    (b) Assigning, revising, revalidating, or revoking priority levels 
as necessary or upon request of service users concerned, and denying 
requests for priority actions as necessary, using paragraph 16 of this 
directive. Under circumstances short of exercise of Presidential war 
emergency powers under section 706 of the Communications Act and time 
permitting, coordinate such changes in priority level assignments in 
advance with requesting and/or affected parties. Action on such requests 
will be completed within 30 days of receipt.
    (c) Maintaining data on priority level assignments.
    (d) Periodically forwarding to the FCC and Director, OSTP, lists of 
priority actions for review and approval.
    (e) Periodically initiating reconciliation.

NSEP service requirement was adequately handled; and whether any 
additional charges were incurred. These reports will be due by April 
30th for the preceding July through December and by October 31st for the 
preceding January through June time periods.
    (3) Function (on a discretionary basis) as a sponsoring Federal 
organization. (See paragraph 10d below.)
    d. Sponsoring Federal Organizations. Sponsoring Federal 
organizations will:
    (1) Review and decide whether to sponsor private industry (including 
telecommunication service vendors) requests for priority actions. 
Federal organizations will forward sponsored requests with 
recommendations for disposition to the Manager, NCS. Recommendations 
will be based on paragraph 16 of this directive.
    (2) Forward notification of priority actions or denials of requests 
for priority actions to the requesting private industry entities, for 
disposition.
    (3) Cooperate with the Manager, NCS, during reconciliation,

Manager, NCS. Recommendations will be based on paragraph 16 of this 
directive. This does not preclude public and private power utility 
companies from obtaining sponsorship elsewhere.
    (2) Forward notification of priority actions or denials of requests 
for priority actions to the requesting public and private power utility 
companies for disposition.
    g. Federal Emergency Management Agency. The Federal Emergency 
Management Agency will, in addition to the responsibilities listed in

    h. Federal Organizations. Federal organizations will:
    (1) Ensure that NSEP TSP System users within each organization 
comply with their obligations under the NSEP TSP System.
    (2) Provision and restore government-provided services (which are 
interconnected with commercially provided services assigned a priority 
level pursuant to paragraph 13 of this directive) in accordance with 
NSEP TSP System rules and regulations. (See paragraph 7a(2) of this 
directive.)
    (3) Function (on a discretionary basis) as sponsoring Federal 
organizations for private sector service users (e.g., government 
contractors).
    (4) Cooperate with the Manager, NCS, during reconciliation, 
revalidation, and audits.
    i. Service Users. Service users, or entities acting on their behalf, 
will:
    (1) Identify services requiring priority level assignments and

directive and any supplemental NCS issuances.
    (2) Justify and revalidate all priority level assignments at least 
every three years.
    (3) For services assigned priority levels, ensure (through 
contractual means or otherwise) availability of customer premises 
equipment and wiring necessary for end-to-end service operation by the 
service due date, and continued operation; and, for such services in the 
Emergency NSEP category, by the time that vendors are prepared to 
provide the services. Additionally, designate the organization

request for priority action and apprise the Manager, NCS.
    (8) Upon termination of services that are assigned priority levels, 
or circumstances warranting revisions in priority level assignment 
(e.g., expansion of service), request and justify revocation or 
revision.
    (9) When NSEP treatment is invoked under paragraph 13c of this 
directive, within 90 days following provisioning of the service 
involved, forward to the Manager, NCS complete information identifying 
the time and event associated with the invocation and regarding whether 
the NSEP service requirement was adequately handled and whether any 
additional charges were incurred.
    (10) Cooperate with the Manager, NCS, during reconciliation, 
revalidation, and audits.
    j. Service Vendors. Service vendors will comply with the provisions 
of 47 CFR part 64. When those provisions are superseded by the 
President's war emergency powers under section 706 of the Communications 
Act, vendors will continue to comply with 47 CFR part 64, subject to 
further direction by Director, OSTP.
    11. Preemption of Existing Services. When necessary to provision or 
restore NSEP services, service vendors may preempt services they provide 
as specified below. ``User,'' as used in this section, means any user of 
a telecommunications service, to include both NSEP and non-NSEP 
services. Prior consent by a preempted user is not required.
    a. The sequence in which existing services may be preempted to 
provision NSEP services assigned a provisioning priority level ``E'' or 
restore NSEP services assigned a restoration priority level from ``1'' 
through ``5'':

[[Page 796]]

    (1) Non-NSEP services: If suitable spare services are not available, 
then, based on the considerations in 47 CFR part 64 and the service 
vendor's best judgement, non-NSEP services will be preempted. After 
ensuring a sufficient number of public switched services will remain 
available for public use, based on the service vendor's best judgement, 
such services may be used to satisfy a requirement for provisioning or 
restoring NSEP services.
    (2) NSEP Services: If no suitable spare or non-NSEP services are 
available, then existing NSEP services may be preempted to provision or 
restore NSEP services with higher priority level assignments. When this 
is necessary, NSEP services will be selected for preemption in the 
inverse order of priority level assignment.
    (3) Service vendors who are preempting services will ensure their 
best effort to notify the service user of the preempted service and 
state the reason for and estimated duration of the preemption.
    b. Service vendors may, based on their best judgement, determine the 
sequence in which existing services may be preempted to provision NSEP 
services assigned a provisioning priority of ``1'' through ``5.'' 
Preemption is not subject to the consent of the user whose service will 
be preempted.
    12. Requests for Priority Actions. All service users are required to 
submit requests for priority actions through the Manager, NCS, in the 
format and following the procedures prescribed by the Manager.
    13. Assignment, Approval, Use, and Invocation of Priority Levels.
    a. Assignment and Approval of Priority Levels and Priority Actions.
    (1) Priority level assignments or other priority actions will be 
based upon section 16, NSEP TSP System Categories, Criteria, and 
Priority Levels, of this directive. A priority level assignment or other 
priority action made by the Manager, NCS, will serve as the 
recommendation of the Director, OSTP (on behalf of the EOP) to the FCC. 
If the Director, OSTP does not approve the priority level assignment or 
other priority action made by the Manager, NCS, then the Director can 
direct the Manager, NCS, to revise or revoke the priority level 
assignment or other priority action.
    (2) Until the President's war emergency powers under Section 706 of 
the Communications Act are invoked, priority level assignments or other 
priority actions must be approved by the FCC. (If the FCC does not 
approve the priority level assignment or other priority action, then it 
can direct the Manager, NCS, to revise or revoke the priority level 
assignment or other priority action.) However, the FCC has instructed 
service vendors to implement any priority level assignments or other 
priority actions that are pending FCC approval.
    (3) After invocation of the President's war emergency powers, the 
requirement for FCC approval of priority level assignments or other 
priority actions may be superseded by other procedures issued by the 
Director, OSTP.
    b. Use of Priority Level Assignments.
    (1) All provisioning and restoration priority level assignments for 
services in the Emergency NSEP category will be included in initial 
service orders to vendors. Provision priority level assignments for 
Essential NSEP services, however, will not usually be included in 
initial service orders to vendors. NSEP treatment for Essential NSEP 
services will be invoked and provisioning priority level assignments 
will be conveyed to service vendors only if the vendors cannot meet 
needed service dates through the normal provisioning process.
    (2) Any revision or revocation of either provisioning or restoration 
priority level assignments will also be transmitted to vendors.
    (3) Service vendors shall accept priority levels and/or revisions 
only after assignment by the Manager, NCS. (Note: Service vendors acting 
as prime contractors for NSEP services will accept assigned NSEP 
priority levels only when they are accompanied by the Manager, NCS 
designated service identification (i.e., TSP Authorization Code). 
However, service vendors are authorized to accept priority levels and/or 
revisions from users and contracting activities before assignment by the 
Manager, NCS when service vendors, users, and contracting activities are 
unable to communicate with either the FCC, Director, OSTP, or the 
Manager, NCS. Processing of Emergency NSEP service requests will not be 
delayed for verification purposes.
    c. Invocation of NSEP Treatment. To invoke NSEP treatment for the 
priority provisioning of an NSEP telecommunications service, an 
authorized Federal official either within, or acting on behalf of, the 
service user's organization must make a written or oral declaration to 
concerned service vendor(s) and the Manager, NCS, that NSEP treatment is 
being invoked. Authorized Federal officials include the head or director 
of a Federal agency, commander of a unified/specified military command, 
chief of a military service, or commander of a major military command; 
the delegates of any of the foregoing; or any other officials as 
specified in supplemental procedures issued by the Manager, NCS. The 
authority to invoke NSEP treatment may be delegated only to a general or 
flag officer of a military service, civilian employee of equivalent 
grade (e.g., Senior Executive Service member), Federal Coordinating 
Officer or Federal Emergency Communications Coordinator/Manager, or any 
other such officials specified in supplemental procedures issued by the 
EOP. Delegates must be designated as such in writing,

[[Page 797]]

and written or oral invocations must be accomplished, in accordance with 
supplemental procedures issued by the Manager, NCS.
    14. Resubmission of Circuits Presently Assigned Restoration 
Priorities. All circuits assigned restoration priorities must be 
reviewed for eligibility for initial restoration priority level 
assignment under the provisions of this directive. Circuits assigned 
restoration priorities, and for which restoration priority level 
assignments are requested under paragraph 12 of this directive, will be 
resubmitted to the Manager, NCS. To resubmit such circuits, service 
users will comply with applicable provisions of paragraphs 10i and 13 of 
this directive.
    15. Appeal. Service users or sponsoring Federal organizations may 
appeal any priority level assignment, denial, revision, revocation, 
approval, or disapproval to the Manager, NCS within 30 days of 
notification to the service user. The appellant must use the form or 
format required by the Manager, NCS and must serve the FCC with a copy 
of its appeal. The Manager, NCS will act on the appeal within 90 days of 
receipt. Service users and sponsoring Federal organizations may only 
then appeal directly to the FCC. Such FCC appeal must be filed within 30 
days of notification of the Manager, NCS' decision on appeal. 
Additionally, the Manager, NCS may appeal any FCC revisions, approvals 
or disapprovals to the FCC. All appeals to the FCC must be submitted 
using the form or format required. The party filing its appeal with the 
FCC must include factual details supporting its claim and must serve a 
copy on the Manager, NCS and any other party directly involved. Such 
party may file a response within 20 days, and replies may be filed 
within 10 days thereafter. The Commission will not issue public notices 
of such submissions. The Commission will provide notice of its decision 
to the parties of record. Any appeals to the Manager, NCS that include a 
claim of new information that has not been presented before for 
consideration may be submitted at any time.
    16. NSEP TSP System Categories, Criteria, and Priority Levels.
    a. General. NSEP TSP System categories and criteria, and permissible 
priority level assignments, are defined and explained below.
    (1) The Essential NSEP category has four subcategories (i.e., 
National Security Leadership; National Security Posture and U.S. 
Population Attack Warning; Public Health, Safety, and Maintenance of Law 
and Order; and Public Welfare and Maintenance of National Economic 
Posture). Each subcategory has its own criteria. Criteria are also shown 
for the Emergency NSEP category, which has no subcategories.
    (2) Priority levels of ``1,'' ``2,'' ``3,'' ``4,'' and ``5'' may be 
assigned for provisioning and/or restoration of Essential NSEP 
telecommunication services. However, for Emergency NSEP 
telecommunication services, a priority level ``E'' is assigned for 
provisioning. A restoration priority level from ``1'' through ``5'' may 
be assigned if an Emergency NSEP service also qualifies for such a 
restoration priority level under the Essential NSEP category.
    (3) The NSEP TSP System allows the assignment of priority levels to 
any NSEP telecommunications service across three time periods, or stress 
conditions: Peacetime/Crisis/Mobilization, Attack/War, and Post-Attack/
Recovery. Priority levels will normally be assigned only for the first 
time period. These assigned priority levels will apply through the onset 
of any attack, but it is expected that they would later be revised by 
surviving authorized telecommunication resource managers within the 
Executive Office of the President based upon specific facts and 
circumstances arising during the Attack/War and Post-Attack/Recovery 
time periods.
    (4) Service users may, for their own internal use, assign 
subpriorities to their services assigned priority levels. Receipt of and 
response to any such subpriorities is optional for service vendors.
    (5) The following paragraphs provide a detailed explanation of the 
categories, subcategories, criteria, and priority level assignments, 
beginning with the Emergency NSEP category.
    b. Emergency NSEP. Telecommunication services in the Emergency NSEP 
category are those new services so critical as to be required to be 
provisioned at the earliest possible time, without regard to the costs 
of obtaining them.
    (1) Criteria. To qualify under the Emergency NSEP category, the 
service must meet the criteria of directly supporting or resulting from 
at least one of the following NSEP functions:
    (a) Federal government activity responding to a Presidentially 
declared disaster or emergency as defined in the Disaster Relief Act (42 
U.S.C. 5122).
    (b) State or local government activity responding to a 
Presidentially, state, or locally declared disaster or emergency.
    (c) Response to a state of crisis declared by the National Command 
Authorities (e.g., exercise of presidential war emergency powers under 
Section 706 of the Communications Act, supra).
    (d) Efforts to protect endangered U.S. personnel or property.
    (e) Response to an enemy or terrorist action, civil disturbance, 
natural disaster, or any other unpredictable occurrence that has damaged 
facilities whose uninterrupted operation is critical to NSEP or the 
management of other ongoing crises.

[[Page 798]]

    (f) Certification by the head or director of a Federal agency, 
commander of a unified/specified command, chief of a military service, 
or commander of a major military command, that the telecommunications 
service is so critical to protection of life and property or to NSEP 
that it must be provided immediately.
    (g) A request from an official authorized pursuant to the Foreign 
Intelligence Surveillance Act (50 U.S.C. 1801 et seq. and 18 U.S.C. 
2511, 2518, 2519).
    (2) Priority Level Assignment.
    (a) Services qualifying under the Emergency NSEP category are 
assigned priority level ``E'' for provisioning.
    (b) After 30 days, assignments of provisioning priority level ``E'' 
for Emergency NSEP services are automatically revoked unless extended 
for another 30-day period. A notice of any such revocation will be sent 
to service vendors.
    (c) For restoration, Emergency NSEP services may be assigned 
priority levels under the provisions applicable to Essential NSEP 
services (see paragraph 16.c.). Emergency NSEP services not otherwise 
qualifying for restoration priority level assignment as Essential NSEP 
may be assigned a restoration priority level ``5'' for a 30-day period. 
Such 30-day restoration priority level assignments will be revoked 
automatically unless extended for another 30-day period. A notice of any 
such revocation will be sent to service vendors.
    c. Essential NSEP. Telecommunication services in the Essential NSEP 
category are those required to be provisioned by due dates specified by 
service users, or restored promptly, normally without regard to 
associated overtime or expediting costs. They may be assigned priority 
levels of ``1,'' ``2,'' ``3,'' ``4,'' or ``5'' for both provisioning and 
restoration, depending upon the nature and urgency of the supported 
function, the impact of a lack of service or service interruption upon 
the supported function, and, for priority access to public switched 
services, the user's level of responsibility. Priority level assignments 
will be valid for no more than three years unless revalidated. To be 
categorized as Essential NSEP, a telecommunications service must qualify 
under one of the four subcategories described below: National Security 
Leadership; National Security Posture and U.S. Population Attack 
Warning; Public Health, Safety, and Maintenance of Law and Order; or 
Public Welfare and Maintenance of the National Economic Posture. (Note: 
Under emergency circumstances, Essential NSEP telecommunication services 
may be recategorized as Emergency NSEP and assigned a priority level 
``E'' for provisioning.)
    (1) National Security Leadership. This subcategory will be strictly 
limited to only those telecommunication services essential to national 
survival if nuclear attack threatens or occurs, and critical orderwire 
and control services necessary to ensure the rapid and efficient 
provisioning or restoration of other NSEP telecommunication services. 
Services in this subcategory are those for which a service interruption 
of even a few minutes would have serious adverse impact upon the 
supported NSEP function.
    (a) Criteria. To qualify under this subcategory, a service must be 
at least one of the following:
    (i) Critical orderwire, or control service, supporting other NSEP 
functions.
    (ii) Presidential communications service critical to continuity of 
government and national leadership during crisis situations.
    (iii) National Command Authority communications service for military 
command and control critical to National survival.
    (iv) Intelligence communications service critical to warning of 
potentially catastrophic attack.
    (v) Communications service supporting the conduct of diplomatic 
negotiations critical to arresting or limiting hostilities.
    (b) Priority Level Assignment. Services under this subcategory will 
normally be assigned, during Peacetime/Crisis/Mobilization, priority 
level ``1'' for provisioning and restoration.
    (2) National Security Posture and U.S. Population Attack Warning. 
This subcategory covers those minimum additional telecommunication 
services essential to maintaining an optimum defense, diplomatic, or 
continuity-of-government posture before, during, and after crisis 
situations. Such situations are those ranging from national emergencies 
to international crises, including nuclear attack. Services in this 
subcategory are those for which a service interruption ranging from a 
few minutes to one day would have serious adverse impact upon the 
supported NSEP function.
    (a) Criteria. To qualify under this subcategory, a service must 
support at least one of the following NSEP functions:
    (i) Threat assessment and attack warning.
    (ii) Conduct of diplomacy.
    (iii) Collection, processing, and dissemination of intelligence.
    (iv) Command and control of military forces.
    (v) Military mobilization.
    (vi) Continuity of Federal government before, during, and after 
crisis situations.
    (vii) Continuity of state and local government functions supporting 
the Federal government during and after national emergencies.
    (viii) Recovery of critical national functions after crisis 
situations.
    (ix) National space operations.
    (b) Priority Level Assignment. Services under this subcategory will 
normally be assigned, during Peacetime/Crisis/Mobilization,

[[Page 799]]

priority levels ``2,'' ``3,'' ``4,'' or ``5'' for provisioning and 
restoration.
    (3) Public Health, Safety, and Maintenance of Law and Order. This 
subcategory covers the minimum number of telecommunication services 
necessary for giving civil alert to the U.S. population and maintaining 
law and order and the health and safety of the U.S. population in times 
of any national, regional, or serious local emergency. These services 
are those for which a service interruption ranging from a few minutes to 
one day would have serious adverse impact upon the supported NSEP 
functions.
    (a) Criteria. To qualify under this subcategory, a service must 
support at least one of the following NSEP functions:
    (i) Population warning (other than attack warning).
    (ii) Law enforcement.
    (iii) Continuity of critical state and local government functions 
(other than support of the Federal government during and after national 
emergencies).
    (iv) Hospitals and distribution of medical supplies.
    (v) Critical logistic functions and public utility services.
    (vi) Civil air traffic control.
    (vii) Military assistance to civil authorities.
    (viii) Defense and protection of critical industrial facilities.
    (ix) Critical weather services.
    (x) Transportation to accomplish the foregoing NSEP functions.
    (b) Priority Level Assignment. Services under this subcategory will 
normally be assigned, during Peacetime/Crisis/Mobilization, priority 
levels ``3,'' ``4,'' or ``5'' for provisioning and restoration.
    (4) Public Welfare and Maintenance of National Economic Posture. 
This subcategory covers the minimum number of telecommunication services 
necessary for maintaining the public welfare and national economic 
posture during any national or regional emergency. These services are 
those for which a service interruption ranging from a few minutes to one 
day would have serious adverse impact upon the supported NSEP function.
    (a) Criteria. To qualify under this subcategory, a service must 
support at least one of the following NSEP functions:
    (i) Distribution of food and other essential supplies.
    (ii) Maintenance of national monetary, credit, and financial 
systems.
    (iii) Maintenance of price, wage, rent, and salary stabilization, 
and consumer rationing programs.
    (iv) Control of production and distribution of strategic materials 
and energy supplies.
    (v) Prevention and control of environmental hazards or damage.
    (vii) Transportation to accomplish the foregoing NSEP functions.
    (b) Priority Level Assignment. Services under this subcategory will 
normally be assigned, during Peacetime/Crisis/Mobilization, priority 
levels ``4'' or ``5'' for provisioning and restoration.
    d. Limitations. Priority levels will be assigned only to the minimum 
number of telecommunication services required to support an NSEP 
function. Priority levels will not normally be assigned to back-up 
services on a continuing basis, absent additional justification (e.g., a 
service user specifies a requirement for physically diverse routing or 
contracts for additional continuity-of-service features). The Executive 
Office of the President may also establish limitations upon the relative 
numbers of services which may be assigned any restoration priority 
level. These limitations will not take precedence over laws or executive 
orders. Such limitations shall not be exceeded absent waiver by the 
Executive Office of the President.
    e. Non-NSEP Services. Telecommunication services in the non-NSEP 
category will be those which do not meet the criteria for either 
Emergency NSEP or Essential NSEP.
    17. Authorizing Provision. NCS manuals implementing this directive 
are authorized.
    18. Effective Date. This directive is effective immediately.
    19. Expiration. This directive is in effect until superseded or 
cancelled.

Telecommunications Operations--Shared Resources (SHARES) High Frequency 
                           (HF) Radio Program

September 30, 1988.

    1. Purpose. This directive establishes National Communications 
System (NCS) policies pertaining to operation and use of the Shared 
Resources (SHARES) High Frequency (HF) Radio Program.
    2. Applicability. This directive is binding upon NCS and other 
Executive entities who voluntarily elect to participate in the SHARES HF 
Radio Program.
    3. Authority. This directive is issued under the authority of 
Executive Order No. 12472, ``Assignment of National Security and 
Emergency Preparedness Telecommunications Functions,'' April 3, 1984, 49 
FR 13471 (1984); and NCS Directive 1-1, ``National Communications System 
(NCS) Issuance System,'' November 30, 1987.
    4. References.
    a. Executive Order (E.0.) No. 12472, ``Assignment of National 
Security and Emergency Preparedness Telecommunications Functions,'' 
April 3, 1984, 49 FR 13471 (1984).
    b. National Telecommunications & Information Administration (NTIA), 
``Manual of Regulations and Procedures for Federal Radio Frequency 
Management,'' May, 1986 Edition as revised May, 1987 or current edition/
revision.
    5. General.
    a. E.O. No. 12472 established national policy guidance in support of 
National Security Emergency Preparedness (NSEP) objectives. Executive 
Order No. 12472 mandates that action be taken to ``. . . ensure that a 
national telecommunications infrastructure is developed . . .''. 
Consistent with the Executive Order, functionally similar government 
telecommunications networks should be designed to interchange traffic in 
support of national leadership requirements.
    b. The SHARES HF Radio Program will provide a backup capability to 
exchange critical information among Federal entities to support NSEP. 
Federally controlled HF radio resources will be shared to establish a 
robust NSEP HF radio communications infrastructure. The program involves 
a collection of existing Federally controlled HF radio stations that 
inter-operate to transmit NSEP messages when normal means of 
communication are not available.
    6. Policy.
    a. Any participating Federal entity will accept, to the extent that 
acceptance does not interfere with the mission responsibilities of the 
entity, emergency messages of other Federal entities, or other 
components of the same entity, for transmission by HF radio to the 
addressee or to another participant for relay to the addressee.

[[Page 802]]

    b. A SHARES message is an emergency message to be sent via the 
SHARES network. It consists of information that must be communicated to 
a Federal entity and is of critical importance to the Federal 
Government, the entity's mission, and/or involves the preservation of 
life and the protection of property.
    c. Transmission of SHARES messages will be guided by the policy of 
the agency accepting the message. Advice that a ``SHARES Message'' is to 
be transmitted will serve to notify operating personnel that a critical 
NSEP message requirement exists, and implicitly, that normal 
communication paths are not available.
    7. Responsibilities.
    a. NCS entities participating in the SHARES HF Radio Program will, 
to the maximum extent possible:
    (1) Identify HF stations under their control for participation in 
the SHARES Program.
    (2) Maintain the operational readiness of their SHARES HF stations.
    (3) Provide updated information as necessary for inclusion in a 
SHARES HF Radio Program Directory. Use of Federal frequencies for SHARES 
traffic shall be in accordance with National Telecommunications and 
Information Administration (NTIA) ``Manual of Regulations and Procedures 
for Federal Radio Frequency Management.''
    (4) Ensure participation of available stations in scheduled 
exercises.
    (5) Provide representation, as required, at meetings, briefings, 
conferences, and other official SHARES HF Radio Program activities.
    b. The Manager, NCS, will administer the SHARES HF Radio Program and 
perform the management functions defined below:
    (1) Publish and periodically update, as NCS issuances, a User 
Manual, giving detailed procedures for using SHARES HF Radio Program 
capabilities, and HF Directory of participating Federally controlled HF 
radio stations.
    (2) Develop, schedule, and administer periodic exercises of the 
SHARES HF Radio Program capabilities.
    (3) Perform other functions, as necessary, to improve SHARES 
capabilities.
    8. Authorizing Provision. NCS manuals implementing this directive 
are authorized.
    9. Effective Date. This directive is effective immediately.
    10. Expiration. This directive is in effect until superseded or 
cancelled.

or Universities below, is not more than 15 miles from a historically 
Black college or university, a Tribal College or University, or a

    (2) Has an estimated median annual household income (based on U.S. 
Census Bureau American Community Survey data) of not more than 250 
percent of the poverty line, as that term is defined in section 673(2)

operating reserve funds, maintenance reserve funds, and improvement 
reserve funds.
    Non-fee-based income received by FirstNet means FirstNet's receipt

review and approval process conducted on an annual basis.



Sec.  500.4  Scope of NTIA review of FirstNet proposed fees.

    NTIA shall approve FirstNet proposed fees only if such fees, when 
combined with any non-fee-based income projected to be received by 
FirstNet, are sufficient, but do not exceed the amount necessary, to 
recoup FirstNet's projected total expenses in carrying out its powers, 
duties, and responsibilities under 47 U.S.C. 1401 et seq. for the fiscal 
year involved.



Sec.  500.5  Methodology of NTIA fee review and approval process.

    (a) Fee review approach. To execute NTIA's fee review and approval 
process, NTIA shall utilize FirstNet's submission and FirstNet's 
standard financial documentation.
    (b) Deference to FirstNet on necessary reserve funds. In executing 
NTIA's fee review and approval process, NTIA shall defer to FirstNet 
with respect to its designated amount, use, and retention of necessary 
reserve funds. NTIA shall consider any such designated funds to be a 
part of FirstNet's total expenses in carrying out its powers, duties, 
and responsibilities under 47 U.S.C. 1401 et seq. for the fiscal year 
involved.
    (c) Determination of fee review. (1) NTIA shall make one of the 
following determinations annually upon review of FirstNet's proposed 
fees:
    (i) FirstNet's proposed fees, in aggregate, when combined with any 
projected non-fee-based income to be received by FirstNet, meet but do 
not exceed FirstNet's projected total expenses;
    (ii) FirstNet's proposed fees, in aggregate, when combined with any 
projected non-fee-based income to be received by FirstNet, do not meet 
FirstNet's projected total expenses; or
    (iii) FirstNet's proposed fees, in aggregate, when combined with any 
projected non-fee-based income to be received by FirstNet, exceed 
FirstNet's projected total expenses.
    (2) Upon making any of the determinations in paragraphs (c)(1)(i) 
through (iii) of this section, NTIA will communicate its determination 
in writing to the Chair of the FirstNet Board and the FirstNet Chief 
Executive Officer.
    (d) Outcome of determination of fee review. (1) Should NTIA make the 
determination listed in paragraph (c)(1) of this section, FirstNet may 
assess the proposed fees.
    (2) Should NTIA make one of the determinations listed in paragraph 
(c)(2) or (3) of this section, NTIA will disapprove FirstNet's proposed 
fees, and FirstNet may not assess those proposed fees.
    (e) Revision of proposed fees. Upon a disapproval of FirstNet's 
proposed fees as described in paragraph (d)(2) of this section, or upon 
FirstNet's determination that it must revise NTIA-approved fees to 
ensure compliance with 47 U.S.C. 1428(b), FirstNet shall prepare a 
revised written submission to NTIA, which shall evaluate any proposed 
fees therein consistent with the requirements in Sec. Sec.  500.1 
through 500.5. Should NTIA disapprove of FirstNet's proposed fees 
pursuant to this section, fees approved by NTIA for the prior fiscal 
year may be assessed by FirstNet during the instant fiscal year until 
such time that NTIA approves FirstNet's

[[Page 837]]

proposed fees for the instant fiscal year pursuant to paragraph (g) of 
this section.
    (f) Communication of NTIA fee approval or disapproval. Approval or 
disapproval of FirstNet-proposed fees shall be communicated in writing 
by the Assistant Secretary for Communications and Information and 
Administrator, National Telecommunications and Information 
Administration, U.S. Department of Commerce, to the Chair of the 
FirstNet Board and FirstNet Chief Executive Officer.
    (g) Process and timing of NTIA fee review. For each fiscal year, 
FirstNet and NTIA will abide by the following Fee Review Schedule:
    (1) Prior to assessing fees for a given fiscal year, FirstNet shall 
submit to NTIA its proposed fees for that given fiscal year and all 
standard financial documentation that will support its fee projections 
pursuant to this part.
    (2) No later than 15 days after FirstNet submits items under 
paragraph (g)(1) of this section, NTIA shall either notify FirstNet of 
its approval of the FirstNet proposed fees in accordance with paragraph 
(d) of this section or submit any questions or requests for 
clarifications to FirstNet regarding the submission listed in paragraph 
(g)(1).
    (3) No later than 15 days after FirstNet receives questions or 
requests for clarification from NTIA under paragraph (g)(2) of this 
section, FirstNet shall submit responses to NTIA.
    (4) No later than 15 days after receiving responses from FirstNet 
under paragraph (g)(3) of this section, NTIA shall approve or disapprove 
FirstNet's proposed fees pursuant to paragraph (d) of this section.
    (5) Should NTIA disapprove FirstNet's proposed fees, FirstNet and 
NTIA will abide by the following Revised Fee Review Schedule until such 
time as NTIA approves the revised fees:
