Tetrapol is interoperable with TETRA and with analogue systems in both network and direct mode. The dedicated control channel provides a more robust air interface. Greater range and therefore better coverage is achieved than with other channel access methods (eg, TDMA), giving better reception over wider cell coverage. Tetrapol utilises frequency division multiple access (FDMA) which divides a set of channels amongst users who are each given a portion of the available bandwidth for their permanent use. Tetrapol is a continuous wave transmission that does not pulse. Tetrapol currently has over 80 networks deployed in 34 countries with over 70% of the European digital PMR market. (See Will it work?)īeware of this myth: TETRA is THE (only/preferred) European standard. Since 1996, the TETRAPOL Standard was recognised by the vast majority of the European and International bodies such as the International Telecommunication Union CEPT European Police Co-operation Council ETSI Board (in March 1999 ETSI accepted the Tetrapol Publicly Available Specification TETRAPOL is fully compliant with the ETSI Technical Specifications ) and The Radio Communication Agency. By comparison, Tetrapol is a mature, proven system with a successful history of use in large-scale/national networks, while TETRA implementation continues to be fraught with technical problems.
The first TETRA systems were installed in 1997.

The main differences between these professional mobile radio (PMR) systems and public mobile radio systems such as GSM are faster call set-up, group calls, priority calls, encryption, and ability to make direct calls without connection via a base station.Īlthough TETRA was adopted by the European Telecommunications Standardisation Institute (ETSI) as the European standard, Tetrapol delivered operational systems at an earlier date, rolling out the worlds first large-scale digital PMR network in 1988 (RUBIS for the French National Gendarmarie).
