A living standardOver €10 billion has been invested by users to date on installed TETRA networks and terminals, and the technology remains a ‘living’ standard, continuing its development and evolution through the work of ETSI and the TETRA Association. Available for users looking for one site, or for governments deploying a nationwide public safety network, TETRA offers true interoperability achieved through a strict, independent and tightly controlled process. This gives users the benefit of economies of scale as well as choice, with over 40 terminal models currently available, as well as a wide choice of infrastructure vendors. Ultimately, the decision is taken by the customer, and that’s as it should be. PMR users have never had so much choice or functionality on offer – and TETRA provides the safest choice. The TETRA Association will continue to work with its increasing member base to safeguard competition, innovation and interoperability, and to ensure that users have access to all the information they need with which to make a considered choice of communications service.
