Secure, proven TETRA

TETRA, or Terrestrial Trunked Radio, is the technology of choice worldwide for mission and business-critical communications. Designed specifically for the Professional Mobile Radio (PMR) market and emergency services operators, it provides a completely resilient, durable, and highly secure communications solution.

Trusted TETRA technology with security and reliability at its core

For organisations seeking a solution that is always on, reliable, robust and secure, TETRA provides coverage and capacity exactly when and where it is needed.

Proven in the field and trusted around the world by users, the globally recognised standard delivers mission-critical communications every day. TETRA has a long-term future in critical communications, and continues to innovate and evolve, blending its proven heritage with technological advancements.

Currently in operation in thousands of communications systems worldwide, it is a proven technology and open international standard defined by ETSI, the European Telecommunications Standards Institute, in 1995. With a strong interoperability process, TETRA provides users with a choice of products and vendors and ensures supply chain security.

Its reliability, availability and security are determining factors in its success. Additionally, TETRA’s interoperability in the event of a major incident means that public safety agencies such as police, fire and ambulance services can instantly communicate and collaborate to deliver a rapid response.

Specifically designed for use by government agencies and emergency services, it has become the worldwide standard of choice for an increasing range of sectors, such as transport, energy and mining, whose business and safety-critical operations require the best critical communications technology available.

TETRA has the major advantage over cellular mobile systems in being specifically designed to support a wide variety of specialised, instant Push-To-Talk (PTT) voice call applications, including group, broadcast and individual calling, not to mention off-network Direct Mode Operation (DMO) communications.

Also, unlike commercial cellular networks, TETRA provides prioritised coverage and capacity exactly where it is required, even during busy periods, and delivers much higher levels of redundancy, reliability, availability, robustness and security.
