Terrestrial Trunked Radio
(TETRA) is a digital trunked mobile radio standard developed by
the European Telecommunications Standards Institute
(ETSI). The
purpose of the TETRA
standard was to meet the needs of traditional Professional Mobile
Radio (PMR) user organisations such as those listed below.
The air
interfaces, network interfaces as well as the services and
facilities are specified in sufficient detail to enable
independent manufacturers develop infrastructure and radio
terminal products that would fully interoperate with each other.
For example, radio terminals from different manufacturers can
operate on infrastructures from other manufacturers.
The ability for full
interoperability between different manufacturer's products is a
distinct advantage of open standards developed by ETSI. As the
TETRA standard is supported by several independent manufacturers
this increases competition, provides second source security
and allows a greater choice of terminal products for specific user
applications.

Because the TETRA standard has been
specifically developed to meet the needs of a wide variety of
traditional PMR user organisations it has a scaleable architecture
allowing economic network deployments ranging from single site
local area coverage to multiple site wide area national
coverage.
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.
