Cellular telephony is based on the idea of using radio waves (instead of copper wires or fiber-optic cables) to connect mobile telephones to one another and to the ordinary telephone network. Since devices of this kind were first developed in the 1920s, a variety of different systems have arisen using both analog and digital technology.
