Specifically designed for use by government agencies and emergency services, it has become the worldwide standard of choice for an increasing range of sectors seeking the best critical communications technology available. 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 with transport staff. Its reliability, availability and security are determining factors in its success. TETRA offers a complete, resilient and totally secure, service-rich communications solution.Ĭurrently in operation in thousands of communications systems worldwide, it is a proven technology and, as an open, international standard – defined by ETSI, the European Telecommunications Standards Institute, in 1995 – it gives users access to a multi-vendor market. TETRA is a technology that was designed specifically for the private mobile radio market, with public safety features at the fore.
