1 The basic geographic unit of a wireless PCS or cellular system. A city or county is divided into smaller "cells," each of which is equipped with alow-powered radio
transmitter/receiver. The cells can vary in size depending upon terrain, capacity demands, etc. By controlling the transmissionpower, the radio frequencies assigned to one cell can be
limited to the boundaries of that cell. When a wireless PCS or cellular phone moves from one cell toward another, a computer at the Switching Office monitors the movement and at the
proper time, transfers or hands off the phone call to the new cell and another radio frequency.
2 For July through December.
3 Service revenue generated by subscribers' calls outside of their system areas.
