What is TETRA?

What is TETRA descibes in short what TETRA means, how the TETRA standard has been developed. It provides an overvief of the vertical markets of TETRA and the growth rate of TETRA awards and the number countries that have implemented TETRA for their mission critical communications

According to the ETSI (European Telecommunications Standards Institute) TErrestrial Trunked RAdio (TETRA) is a digital trunked mobile radio standard developed to meet the needs of traditional Professional Mobile Radio (PMR) user organisations for their Mission Critical Communications such as:

Most TETRA networks are implemented by for public safety and security (PSS) users such as police, fire and rescue services and are often owned by governments. Other networks such as networks for Transportation, Oil & Gas and Industry networks are either privately owned or run by network operators who invest in the network and sell their communications services to private companies and government agencies.

The TETRA standard has been specifically developed to meet the needs of a variety of traditional PMR user organisations. This means it has a scaleable architecture allowing economic network deployments ranging from single site local area coverage to multiple site wide area national coverage. TETRA is a global standard for radio communication in the same way that, for example, GSM is the mobile telephony standard.

Some unique PMR services of TETRA are: 

Besides meeting the needs of traditional PMR user organisations, the TETRA standard has also been developed to meet the needs of Public Access Mobile Radio (PAMR) operators. To meet the ever changing user requirements and utilise the latest in technology developments, TETRA continues to be evolved and enhanced with the development of new standards. An example of this is TETRA Release 2, which includes the TETRA Enhanced Data Service (TEDS) that provides wide-band high speed data communication services.
