§ 78.36 Frequency coordination.
(a) Coordination of all frequency assignments for fixed stations in all
bands above 2110 MHz, and for mobile (temporary fixed) stations in the bands
6425-6525 MHz and 17.7-19.7 GHz, will be in accordance with the procedure
established in paragraph (b) of this section, except that the prior
coordination process for mobile (temporary fixed) assignments may be
completed orally and the period allowed for response to a coordination
notification may be less than 30 days if the parties agree. Coordination of
all frequency assignments for all mobile (temporary fixed) stations in all
bands above 2110 MHz, except the bands 6425-6525 MHz and 17.7-19.7 GHz, will
be conducted in accordance with the procedure established in paragraph (b)
of this section or with the procedure in paragraph (d) of this section.
Coordination of all frequency assignments for all fixed stations in the band
1990-2110 MHz will be in accordance with the procedure established in
paragraph (c) of this section. Coordination of all frequency assignments for
all mobile (temporary fixed) stations in the band 1990-2110 MHz will be
conducted in accordance with the procedure in paragraph (d) of this section.
(b) For each frequency coordinated under this part, the interference
protection criteria in 47 CFR 101.105(a), (b), and (c) and 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 47 CFR 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:
(A) Applicant's name and address,
(B) Transmitting station name,
(C) Transmitting station coordinates,
(D) Frequencies and polarizations to be added, changed or deleted,
(E) Transmitting equipment type, its stability, actual output power,
emission designator, and type of modulation (loading),
(F) Transmitting antenna type(s), model, gain and, if required, a radiation
pattern provided or certified by the manufacturer,
(G) Transmitting antenna center line height(s) above ground level and ground
elevation above mean sea level,
(H) Receiving station name,
(I) Receiving station coordinates,
(J) Receiving antenna type(s), model, gain, and, if required, a radiation
pattern provided or certified by the manufacturer,
(K) Receiving antenna center line height(s) above ground level and ground
elevation above mean sea level,
(L) Path azimuth and distance,
(M) Estimated transmitter transmission line loss expressed in dB,
(N) Estimated receiver transmission line loss expressed in dB,
(O) For a system utilizing ATPC, maximum transmit power, coordinated
transmit power, and nominal transmit power.
Note to paragraph (b)(2)(ii): The position location of antenna sites shall
be determined to an accuracy of no less than ±1 second in the horizontal
dimensions (latitude and longitude) and ±1 meter in the vertical dimension
(ground elevation) with respect to the National Spacial Reference System.
(iii) For transmitters employing digital modulation techniques, the
notification should clearly identify the type of modulation. Upon request,
additional details of the operating characteristics of the equipment must
also be furnished;
(iv) Response to notification should be made as quickly as possible, even if
no technical problems are anticipated. Any response to notification
indicating potential interference must specify the technical details and
must be provided to the applicant, in writing, within the 30-day
notification period. Every reasonable effort should be made by all
applicants, permittees and licensees to eliminate all problems and
conflicts. If no response to notification is received within 30 days, the
applicant will be deemed to have made reasonable efforts to coordinate and
may file its application without a response;
(v) The 30-day notification period is calculated from the date of receipt by
the applicant, permittee, or licensee being notified. If notification is by
mail, this date may be ascertained by:
(A) The return receipt on certified mail;
(B) The enclosure of a card to be dated and returned by the recipient; or
(C) A conservative estimate of the time required for the mail to reach its
destination. In the last case, the estimated date when the 30-day period
would expire should be stated in the notification.
(vi) An expedited prior coordination period (less than 30 days) may be
requested when deemed necessary by a notifying party. The coordination
notice should be identified as “expedited” and 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 therefore;
(viii) Where a number of technical changes become necessary for a system
during the course of coordination, an attempt should be made to minimize the
number of separate notifications for these changes. Where the changes are
incorporated into a completely revised notice, the items that were changed
from the previous notice should be identified. When changes are not numerous
or complex, the party receiving the changed notification should make an
effort to respond in less than 30 days. When the notifying party believes a
shorter response time is reasonable and appropriate, it may be helpful for
that party to so indicate in the notice and perhaps suggest a response date;
(ix) If, after coordination is successfully completed, it is determined that
a subsequent change could have no impact on some parties receiving the
original notification, these parties must be notified of the change and of
the coordinator's opinion that no response is required;
(x) Applicants, permittees and licensees should supply to all other
applicants, permittees and licensees within their areas of operations, the
name, address and telephone number of their coordination representatives.
Upon request from coordinating applicants, permittees and licensees, data
and information concerning existing or proposed facilities and future growth
plans in the area of interest should be furnished unless such request is
unreasonable or would impose a significant burden in compilation;
(xi) Parties should keep other parties with whom they are coordinating
advised of changes in plans for facilities previously coordinated. If
applications have not been filed 6 months after coordination was initiated,
parties may assume that such frequency use is no longer desired unless a
second notification has been received within 10 days of the end of the 6
month period. Renewal notifications are to be sent to all originally
notified parties, even if coordination has not been successfully completed
with those parties; and
(xii) Any frequency reserved by a licensee for future use in the bands
subject to this part must be released for use by another licensee,
permittee, or applicant upon a showing by the latter that it requires an
additional frequency and cannot coordinate one that is not reserved for
future use.
(c) For each frequency coordinated under this part, the following frequency
usage coordination procedures will apply:
(1) General requirements. Applicants are responsible for selecting the
frequency assignments that are least likely to result in mutual interference
with other licensees in the same area. Applicants may consult local
frequency coordination committees, where they exist, for information on
frequencies available in the area. Proposed frequency usage must be
coordinated with existing licensees and applicants in the area 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, for major amendment to a
pending application, or for major modification to a license.
(2) To be acceptable for filing, all applications for regular authorization,
or major amendment to a pending application, or major modification to a
license, must include a certification attesting that all co-channel and
adjacent-channel licensees and applicants potentially affected by the
proposed fixed use of the frequency(ies) have been notified and are in
agreement that the proposed facilities can be installed without causing
harmful interference to those other licensees and applicants.
(d) For each frequency coordinated under this part, applicants are
responsible for selecting the frequency assignments that are least likely to
result in mutual interference with other licensees in the same area.
Applicants may consult local frequency coordination committees, where they
exist, for information on frequencies available in the area. In selecting
frequencies, consideration should be given to the relative location of
receive points, normal transmission paths, and the nature of the
contemplated operation.
