History

Matra/EADS developed TETRAPOL and delivered an operational digital trunked radio system at an early date. Among the first users was the French National Gendarmerie in 1988 for its RUBIS system.

TETRAPOL currently has 80 networks deployed in 34 countries and claims 70% of the European Digital public mobile radio (PMR) market.

EADS (Connexity) and Siemens (S-PRO) are among the major manufacturers of professional radio systems based on the TETRAPOL specification.

Alternative Solutions

TETRA is an open standard by ETSI. TETRA is a more recent standard than Tetrapol taking over concepts from cell phones. It is favored in Europe for its extensibility and lower entry barrier for competitors in the market. Networks can be found worldwide.
