TETRA Training by TONEX

TETRA Training Course by TONEX introduces concepts behind TErrestrial Trunked RAdio (TETRA), an open digital standard defined by the European Telecommunications Standards Institute (ETSI) specifically for the needs of the most demanding professional mobile radio users, emergencies and disasters.

Learn about TETRA  features, services, architecture, addressing, system details, air interface, operations, security, vulnerabilities, flexibilities, and durability.

TErrestrial Trunked RAdio (TETRA) is a digital trunked mobile radio standard developed to meet the needs of traditional Professional Mobile Radio (PMR) user organizations developed by ETSI.

Learn how TETRA standard has been specifically developed to meet the needs of a variety of traditional PMR user organizations such as public safety and governments.

Some unique PMR services of TETRA are:

  • Wide area fast call set-up “all informed net” group calls
  • Direct Mode Operation (DMO) allowing “back to back” communications between radio terminals independent of the network
  • High level voice encryption to meet the security needs of public safety organizations
  • An Emergency Call facility that gets through even if the system is busy
  • Full duplex voice for PABX and PSTN telephony communications
  • TETRA Release 2 or TETRA Enhanced Data Service (TEDS) that provides wideband high speed data communication services
