  §  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.
