Cellular Radio = mobile communications
A system which provides a simple, convenient means of communication for people who wish to keep in touch when travelling. The first mobile communication system was ship-borne radio, and there have since been widespread developments in the field of military communications. In modern times the term also refers to personal communication systems such as CB radio, radio paging, and car and pocket phones which use cellular radio.
Cellular radio employs local radio transmitters, covering small areas (cells), which receive and transmit calls in association with the telecommunications network. Direct-dial calls using special handsets can be made on foot, from cars and trains, and now from aircraft.
