TETRA, or Terrestrial Trunked Radio is a professional mobile communication system based on time-division multiple access (TDMA) technology. It is designed and developed by ETSI (European Telecommunications Standards Institute), to meet the requirements of professional departments in Europe for mobile communication, and it is a global standard for digital trunking radio. The TETRA standard was initially used in Europe but is now rapidly implemented in other parts of the world. The complete TETRA system serves mission-critical organizations and their users, can provide real-time and reliable communication, and is used in different industries such as public safety, transportation, utilities, oil & gas, and more.
TETRA system is a very flexible digital trunking standard that is trusted worldwide. It provides the benefits of digital radio while still keeping the advantages of a PMR system.
It can provide command and dispatch, data transmission, and voice services on the same technical platform. In addition to multi-group dispatch functions, it also provides short data services (SDS), packet data services, and digital full-duplex voice calls services.
Built to adapt to the toughest of environments, the voice call can be quickly established and the delay is short. In case of network disconnection, the mobile /portable device is still available，and it can switch to "Direct Mode" to directly share the channel (walkie-talkie mode).
Compared to GSM, TETRA technology uses much lower frequencies and provides a longer range.
TETRA is an open standard and its IOP test enables interoperability across vendors.
Offers all modes of one-to-one, one-to-many, and many-to-many communication compared to analog radios that can transmit data on the same network.
Supporting TETRA encryption (E2EE and AIE), authentication, air interface encryption, and end-to-end encryption.
It is used in scenarios of daily operations, major events security, emergency management, and others.
