Average Terrain. The average elevation of terrain between 3 and 16 kilometers from the antenna site.
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.
Mobile Service. A radiocommunication service between mobile and land stations, or between mobile stations.
Narrowband PCS. PCS services operating in the 901-902 MHz, 930-931 MHz, and 940-941 MHz bands.

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.
