Sec.  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 17.719.7 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 17.719.7 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) Frequency coordination for all fixed stations in all bands above 2110
   MHz, and for all mobile (temporary fixed) stations in the bands 6425–6525
   MHz and 17.719.7 GHz. For each frequency authorized under this part, the
   interference  protection criteria in  Sec. 101.105(a), (b), and (c) of this
   chapter and the frequency usage coordination procedures in  Sec. 101.103(d) of
   this chapter will apply, except that only stations in the bands 6425–6525
   MHz and 17.719.7 GHz are subject to the provision in  Sec. 101.103(d) requiring
   compliance with  Sec. 101.21(f) of this chapter in coordinating frequency usage
   with stations in the fixed satellite service.

   (c) Frequency coordination for all fixed stations in the band 1990–2110 MHz.
   For each frequency authorized 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) Frequency coordination for all mobile (temporary fixed) stations in all
   bands above 1990 MHz, except the bands 6425–6525 MHz and 17.719.7 GHz. For
   each frequency authorized 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.
