A is a network of handheld (cell phones) in which each phone communicates with the by through a local antenna at a cellular base station (cell site). The coverage area in which service is provided is divided into a mosaic of small geographical areas called "cells", each served by a separate low power multichannel and antenna at a base station. All the cell phones within a cell communicate with the system thr.
