The development of interworking interfaces between TETRA systems and mission-critical broadband systems.

Proposing and developing solutions for the development of mission critical broadband services.

The provision and development of proportionate security measures for TETRA and mission critical communications services.

Identifying requirements for mission and business critical broadband services that will enable an evolution of digital narrowband PMR services to mobile broadband.

In addition to the ongoing maintenance and development of the TETRA standard their activities include: Our Role & ActivitiesĮTSI technical committee TETRA and Critical Communications Evolution (TCCE) produces the TETRA (Terrestrial Trunked Radio) standard which delivers frequency spectrum efficient digital PMR and PAMR system to support voice and data services using techniques such as Trunking, Time Division Multiple Access (TDMA) methods and a variety of efficient modulation schemes for increased data throughput. This includes TETRA Release 2, which includes the TETRA Enhanced Data Service (TEDS) that provides wideband high speed data communication services. To meet the ever changing user requirements and utilize the latest technology developments, TETRA continues to be evolved and enhanced with the development of new standards.

Full duplex voice for PABX and PSTN telephony communicationsīesides meeting the needs of traditional PMR user organizations, the TETRA standard has also been developed to meet the needs of Public Access Mobile Radio (PAMR) operators.

An Emergency Call facility that gets through even if the system is busy.

High level voice encryption to meet the security needs of public safety organizations.

Direct Mode Operation (DMO) allowing 'back to back' communications between radio terminals independent of the network.

Wide area fast call set-up 'all informed net' group calls.

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.

The TETRA standard has been specifically developed to meet the needs of a variety of traditional PMR user organizations. TErrestrial Trunked RAdio (TETRA) is a digital trunked mobile radio standard developed to meet the needs of traditional Professional Mobile Radio ( PMR) user organizations such as:
