A system of mobile telephony whereby a country is divided into thousands of small areas(cells), each of which is served by its own "base station" for low-powered radio transmissions. This allows a user in one cell to transmit on the same frequency as another user in another cell without interfering in each other's conversation. Cellular networks may employ analogue or digital transmission. Existing networks are largely analogue, while new networks use the European GSM digital standard.
