Secure, reliable, robust, and feature rich TETRA is fully scalable, from a single site network at an oil refinery, to a large nationwide public safety network.

TETRA systems meet the unique requirements of mission critical communications from airports to oil and gas, and utilities to public safety. TETRA is fully scalable to grow in line with your user demands, from single-cell systems to a nationwide network. TETRA provides feature rich voice and data communications with a wide range of available products from well know and established manufacturers including ATEX. Using an IP backbone it is easy to add intelligence to your system. From applications to track your personnel to managing your radio fleet. The IP-based connectivity of the individual network elements allows you to use existing IP infrastructure.

Servicom are able to supply everything from entire new systems to upgrades and extensions of current installations. Our engineers and designers can work with you to design your system which can be supplied as an outright purchase or on a fully managed basis.



TETRA was published as a standard by ETSI, European Telecommunications Standards Institute, first in 1990. This has evolved and is well established. TETRA systems are the mainstay for public safety systems throughout Europe, the Middle East, Russia and the Far East.

TETRA uses Time Division Multiple Access (TDMA) with four digital user channels on one radio carrier of 25 kHz bandwidth. TETRA uses (E2EE and AIE) encryption and authentication, combined with excellent noise cancelling voice quality thanks to digital VOCODER technology, ensures every communication is transmitted clearly and securely.

TETRA terminals can operate in a full-duplex direct connection to other TETRA users or such services as telephone networks (PTSN/PBX) or dispatchers. Emergency buttons, provided on the terminals, enable the users to transmit emergency signals, to the dispatcher, overriding any other activity taking place at the same time.

With TETRA it is also possible for terminals to work in a one-to-one (back to back DMO mode) “walkie-talkie” only with reduced call range when operating outside of a network connection.
