Definition - What does Cellular Network mean? A cellular network is a radio network distributed over land through cells where each cell includes a fixed location transceiver known as base station. These cells together provide radio coverage over larger geographical areas.
Cellular networks offer a number of desirable features: 1  More capacity than a single large transmitter, since the same frequency can be used for multiple links as long as they are in different cells. 2  Mobile devices use less power than with a single transmitter or satellite since the cell towers are closer.
