A
cellular network or
mobile network is a communication network where the last link is wireless. The network is distributed over land areas called cells, each served by at least one fixed-location
transceiver, known as a
cell site or
base station. This base station provides the cell with the network coverage which can be used for transmission of voice, data and others. In a cellular network, each cell uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed bandwidth within each cell.
