Trunked radio systems include towers with repeaters and controllers for wide-area coverage, also known as Repeater Service, or Wide-Area Coverage Service. These systems extend the range of radio communication throughout a large geographic area and allow a large group of users to share relatively few radio frequencies by dynamically assigning frequencies, then releasing the frequency back to a pool.- Category ID : 52651
Information on several Motorola systems, the EDACS system which is operated by the City of Clearwater, as well as conventional frequencies for the Greater Tampa Bay Area.
Communications system and method of operation. A typical operational function, using timing information inherent in the transmissions, is the encryption/decryption process within the Trans European Trunked Radio (TETRA) standard.
TETRA and Critical Communications Association supports the development of TETRA standards and promotes adoption for terrestrial trunked radio, an open digital trunked radio standard defined by the European Telecommunications Standardisation Institute .
