A cellular network is a network of handheld mobile phones (cell phones) in which each phone communicates with the telephone network by radio waves 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 transceiver and antenna at a base station. All the cell phones within a cell communicate with the system thr
Each base station has a number of radio channels, or frequencies, to communicate with mobile phones. Because this number of frequencies is limited, frequencies are often reused in
All the cell phones within a cell communicate with the system through that cell''s antenna, on separate frequency channels assigned by the base station from a common pool of frequencies
Base stations emit radiofrequency electromagnetic fields (RF EMF) in the range from several hundred MHz to several GHz. The exact frequency bands used differ between technologies
