§ 74.638   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 paragraph, the interference
   protection criteria in 47 CFR 101.105(a), (b), and (c) and the frequency
   usage coordination procedures in 47 CFR 101.103(d) will apply.

   (c) For each frequency coordinated under this paragraph, 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 paragraph, 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.
