What is TETRA used for?
TETRA systems are designed to offer communications on the move for demanding professional users for whom communications is critical to their roles or businesses.
For example TETRA technology is used to provide greatly improved communications to the emergency services and other public safety organisations, public utilities, transport organisations and other users of mobile communications such as the oil and gas industry and distribution companies.
Which countries use TETRA?
Since 1997, when the first network was opened at Gardermoen Airport in Norway, TETRA has become well-established in over 100 countries, including the USA and Canada. More information about TETRA may be found in the TETRA Fact Sheet and Pocket Guide produced by the TETRA and Critical Communications Association (the Pocket Guide is available in a variety of languages). Both documents open in new windows.
What are the features of TETRA that make it more useful to professional users than mobile phones?
TETRA offers secure, reliable and versatile communications with digital call quality. The features available include transmission of voice, data and pictures, encryption, managed fallback to provide resilience and the ability to use direct mode operation to set up local communications groups, for example at the scene of a major incident.
