TETRA is a digital trunked radio standard for the private/professional mobile radio (PMR) market. BT's Airwave service, a nation-wide mobile radio service designed to serve the needs of the police and other public safety organisations in England, Wales and Scotland, is based on TETRA and the inherent security of TETRA is an essential element of the service.
