TETRA (Terrestrial Trunked Radio) is the World's preferred
Government communications infrastructure. TETRA, a cellular,
trunked communications system, is similar in architecture to
commercial cell-phone systems. Many governments are implementing
single, countrywide, TETRA infrastructures as their new digital
communication system for their key agencies. These include Police,
Ambulance Military, Fire and other government users.
TETRA delivers: Secure, reliable trunked and direct-mode
communications, interoperability between agencies and the ability
to send both voice and data. Interoperability is facilitated by the
ability to make point-to-point calls between all users on the
Network and through Talkgroups.
The TETRA infrastructure consists of: Fixed base-stations,
Switching and Management Infrastructure (SwMI) and the mobile
The UK is a World-leader in the implementation of TETRA and
pioneered the implementation of TETRA for airborne use. Cobham
Antenna Systems' involvement with this work since the beginning
means that it is the most experienced provider of
avionics-standard airborne TETRA systems. Cobham Antenna Systems
has supplied avionics standard airborne TETRA systems for a
wide-range of Government users, in the UK and Internationally.
