Any of the networks enabling mobile telephones to connect to the main telephone system. Originally established in the UK jointly by British Telecom and Securicor (as Cellnet), it consists of a number of adjacent cells, each containing a transmit/receive station connected to the main telephone network and reached by the mobile subscriber using a battery-operated portable radiotelephone. As subscribers move from one geographical cell to another (e.g. by car), they are automatically switched to receive signals from the new area.
