   Average Terrain. The average elevation of terrain between 3 and 16
   kilometers from the antenna site.

   Base Station. A land station in the land mobile service.

   Broadband PCS. PCS services operating in the 1850-1890 MHz, 1930-1970
   MHz, 2130-2150 MHz, and 2180-2200 MHz bands.

   Effective Radiated Power (e.r.p.) (in a given direction). The product
   of the power supplied to the antenna and its gain relative to a
   half-wave dipole in a given direction.

   Equivalent Isotropically Radiated Power (e.i.r.p.). The product of the
   power supplied to the antenna and the antenna gain in a given direction
   relative to an isotropic antenna.

   Fixed Service. A radiocommunication service between specified fixed
   points.

   Fixed Station. A station in the fixed service.

   Land Mobile Service. A mobile service between base stations and land
   mobile stations, or between land mobile stations.

   Land Mobile Station. A mobile station in the land mobile service
   capable of surface movement within the geographic limits of a country
   or continent.

   Land Station. A station in the mobile service not intended to be used
   while in motion.

   Mobile Service. A radiocommunication service between mobile and land
   stations, or between mobile stations.

   Mobile Station. A station in the mobile service intended to be used
   while in motion or during halts at unspecified points.

   Narrowband PCS. PCS services operating in the 901-902 MHz, 930-931 MHz,
   and 940-941 MHz bands.

   National Geodetic Reference System (NGRS): The name given to all
   geodetic control data contained in the National Geodetic Survey (NGS)
   data base. (Source: National Geodetic Survey, U.S. Department of
   Commerce)

   PCS Relocator. A PCS entity that pays to relocate a fixed microwave
   link from its existing 2 GHz facility to other media or other fixed
   channels.

   Personal Communications Services (PCS). Radio communications that
   encompass mobile and ancillary fixed communication that provide
   services to individuals and businesses and can be integrated with a
   variety of competing networks.

   Universal Licensing System. The Universal Licensing System (ULS) is the
   consolidated database, application filing system, and processing system
   for all Wireless Radio Services. ULS supports electronic filing of all
   applications and related documents by applicants and licensees in the
   Wireless Radio Services, and provides public access to licensing
   information.

   UTAM. The Unlicensed PCS Ad Hoc Committee for 2 GHz Microwave
   Transition and Management, which coordinates relocation in the
   1910-1930 MHz band.

   Voluntarily Relocating Microwave Incumbent A microwave incumbent that
   voluntarily relocates its licensed facilities to other media or fixed
   channels.
