Tetra uses Time Division Multiple Access (TDMA), with 25 kHz spacing between carriers, providing four user channels on one radio carrier A low digital data transmission rate ensures that both point-to-point and point-to-multipoint transfer can be used. A Tetra system can support different types of data communication including status messages, short data services, packet-switched data and circuit-switched data. In addition, Tetra systems can communicate in either trunked-mode operation or direct-mode operation by using switching and management infrastructure comprising of TETRA base stations.

Tetra System Features
TETRA terminals utilise full-duplex direct connection (the same principal as a mobile phone) to other TETRA users, however, the common mode of operation is in a group calling mode in which a single button push will connect the user to the users in a selected call group or to a dispatcher.
It can also be possible for the terminal to act as a one-to-one two-way radio, utilising the radio network so that normal range limitations are not affected.
