A trunked radio system is a two-way radio system that uses a control channel to automatically assign frequency channels to groups of user radios. In a traditional half-duplex land mobile radio system a group of users (a talkgroup ) with mobile and portable two-way radios communicate over a single shared radio channel, with one user at a time ...
Terrestrial Trunked Radio [1] (TETRA; formerly known as Trans-European Trunked Radio), a European standard for a trunked radio system, is a professional mobile radio [2] and two-way transceiver specification.
Trunking in telecommunication originated in telegraphy, and later in telephone systems where a trunk line is a communications channel between telephone exchanges. Other applications include the trunked radio systems commonly used by police agencies. [1] In the form of link aggregation and VLAN tagging, trunking has been applied in computer ...
In Type II systems the trunk system maintains a database that determines each radio's affiliation. Another difference between the systems is that Type I systems are arranged in a fleet-subfleet hierarchy. For example, it is possible for a city using a Type I system to designate four fleets, each with eight subfleets.
In radio communication, a control channel is a central channel that controls other constituent radios by handling data streams. It is most often used in the context of a trunked radio system , where the control channel sends various data which coordinates users in talkgroups .

For example, articles about blocking and traffic theory used in trunked radio systems, base stations, AMPS, remote control consoles, or transmitter antenna combiners in two-way radio systems belong in the Wireless ...
TETRAPOL is a fully digital, FDMA, professional mobile radio system for closed user groups, standardizing the whole radio network from data and voice terminal via base stations to switching equipment, including interfaces to the Public switched telephone network and data networks. End-to-end encryption is an integral part of the standard.
