Sec.  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  Sec. 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
    Sec. 80.70(a).

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