3 Proven Strategies To Overcome The Obstacles Of LMR Communications Download My  Guide

TETRA Digital Radio

The Accepted Standard For Critical Communications

TETRA is an open standard developed by the European Telecommunications Standards Institute (ETSI), and is designed specifically for government agencies, public safety networks, transport services, public utilities, oil and gas, and large enterprises.

As the accepted radio standard for critical communications, TETRA is used around the world to ensure resilient and secure communication while protecting citizens.

At Leonardo, we provide LMR technology, such as TETRA, to the public safety and critical infrastructure markets to help them meet their mission-critical needs. 

TETRA: Features

  • TETRA uses time division multiple access (TDMA) with four user channels on one radio carrier and 25 kHz spacing between carriers.
  • In addition to voice and dispatch services, TETRA supports several types of data communications, including status messages and short data services (SDS).
  • TETRA mobile stations can communicate using direct mode operation (DMO) or trunked mode operation (TMO).

The Adaptable Platform

Legacy LMR technology platforms often have proprietary features and restrictions that result in forced obsolescence and upgrades. Another result is limited competition and increased costs.

That’s why Leonardo’s digital LMR solutions and architectures are based on state-of-the-art protocols that enable lower first and lifecycle costs, obsolescence protection and the flexibility to choose the combination of solutions that match your needs.

TETRA: Benefits

Security And Privacy
  • Security And Privacy

    Communication security is critical for public safety agencies and the military. To protect against eavesdropping, TETRA uses digitally encoded voice encryption algorithms, such as air interface encryption and end-to-end encryption.

Effective Dispatch
  • Effective Dispatch

    GPS-enabled TETRA radios and terminals allow you to view individuals and vehicles by location. This data is complemented by integrated applications that present a real-time overview of operational intelligence to help recommend the most appropriate resource to send to incidents.

Multiple Methods Of Data Delivery
  • Multiple Methods Of Data Delivery

    Users can access data via a wide range of applications ranging from location information to the delivery of mission-critical images and video. TETRA offers a variety of data features to support these applications and delivers them with the same quality and security as voice services on the same network.
