§  22.913   Effective radiated power limits.

   The effective radiated power (ERP) of transmitters in the Cellular
   Radiotelephone Service must not exceed the limits in this section.

   (a) Maximum ERP. In general, the effective radiated power (ERP) of base
   transmitters and cellular repeaters must not exceed 500 Watts. However,
   for those systems operating in areas more than 72 km (45 miles) from
   international borders that:

   (1) Are located in counties with population densities of 100 persons or
   fewer per square mile, based upon the most recently available
   population statistics from the Bureau of the Census; or,

   (2) Extend coverage on a secondary basis into cellular unserved areas,
   as those areas are defined in §  22.949, the ERP of base transmitters
   and cellular repeaters of such systems must not exceed 1000 Watts. The
   ERP of mobile transmitters and auxiliary test transmitters must not
   exceed 7 Watts.

   (b) Height-power limit. The ERP of base transmitters must not exceed
   the amount that would result in an average distance to the service area
   boundary of 79.1 kilometers (49 miles) for cellular systems authorized
   to serve the Gulf of Mexico MSA and 40.2 kilometers (25 miles) for all
   other cellular systems. The average distance to the service area
   boundary is calculated by taking the arithmetic mean of the distances
   determined using the procedures specified in §  22.911 for the eight
   cardinal radial directions.

   (c) Coordination exemption. Licensees need not comply with the
   height-power limit in paragraph (b) of this section if the proposed
   operation is coordinated with the licensees of all affected cellular
   systems on the same channel block within 121 kilometers (75 miles) and
   concurrence is obtained.
