§ 24.5   Terms and definitions.

   Assigned Frequency. The center of the frequency band assigned to a station.

   Authorized Bandwidth. The maximum width of the band of frequencies permitted
   to be used by a station. This is normally considered to be the necessary or
   occupied bandwidth, whichever is greater.

   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.

   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.
