Tetra network

Tetra is a trunked radio with radio cells. Like a GSM network, the Tetra network is a radio cell-based network in which the mobile radios communicate with the Tetra Base Station (TBS).

The Tetra network does not have a Base Station Controller( BSC) like the GSM network; in Tetra, the base stations are directly connected to an exchange, which in turn communicates with other exchanges, Digital Exchange for Tetra (DXT), and the Dispatcher Station( DST).

TETRA network architecture

The transition of a mobile station to another base station occurs automatically when a base station with higher field strength is detected. Roaming between different Tetra networks is possible via the Inter System Interface( ISI), a unified interface for communication between different Tetra networks.
