§  80.479   Assignment and use of frequencies for AMTS.

   (a) The frequencies assignable to AMTS stations are listed in subpart H
   of this subpart.

   (b) The transmissions from a station of an AMTS geographic area
   licensee may not exceed a predicted 38 dBu field strength at the
   geographic area border, unless all affected co-channel geographic area
   licensees agree to the higher field strength. The predicted 38 dBu
   field strength is calculated using the F(50, 50) field strength chart
   for Channels 7 through 13 in § 73.699 (Fig. 10) of this chapter, with a
   9 dB correction factor for antenna height differential. Geographic area
   licensees must coordinate to minimize interference at or near their
   geographic area borders, and must cooperate to resolve any instances of
   interference in accordance with the provisions of § 80.70(a).

   (c) AMTS frequencies may be used for mobile-to-mobile communications if
   written consent is obtained from all affected licensees.
