TETRA Systems benefits

TETRA (Terrestrial Trunked Radio) has been developed by industry experts 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 phones with fast data communications and the work group capabilities of PMR. 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.
  • Full interoperability (IOP) with all TETRA terminals allows you to freely choose and combine any of your favourite terminal brands.
