Figure: Max. received power in
downlink of a TETRA network in a
city.
The terrestrial trunked radio (TETRA)
air interface is an open digital trunked
radio standard defined by the European
Telecommunications Standardisation Institute
(ETSI)
to meet the needs of the most demanding
private mobile radio (PMR) and public access
mobile radio (PAMR) users.
Cellular TDMA networks like TETRA require an
accuarte network planning because of the
frequency reuse and the requirement of
sufficient co-channel interference. Accurate
propagation
models are therefore required for a
detailed analysis of the scenario. Besides
the coverage and interference situation also
the max. achievable data rate can be predicted.

The following
air interfaces are
pre-defined:
TETRA
(frequency band: 380 -
400 MHz)
Further air interfacess
(incl.
modifications of pre-defined
air interfaces)
and frequency
bands can be
defined by the user.
