Terrestrial Trunked Radio (TETRA) has been developed by industryexperts alongside the European Telecommunications Standards Institute (ETSI) and has emerged as the unchallenged standard for the most demanding and professional users of radio communications worldwide.

TETRA technology brings new outstanding features to mobile communications, by combining the features of mobile cellular phones with fast data communications and the workgroup capabilities of PMR. All communications over TETRA are reassuringly private, secure and robust. The fully digital technology provides consistent and low noise voice quality. Further the TETRA technology is inherently efficient in the way it uses the frequency spectrum.


Some of the key services differentiating TETRA from other wireless technologies include individual simplex and duplex calls, group calls, pre-emptive emergency and priority calls, dynamic group number assignment, call authentication, late entry, voice encryption, packet data services.

As a global open standard, TETRA allows a mix of different manufacturers’ TETRA equipment on the same system. Today, TETRA has been adopted and supported by a large number of radio communication suppliers worldwide.
