Radio performance of logical channels defined in TETRA standard

TETRA (Trans-European Trunked RAdio) is a digital mobile radio standard for voice and data transmission. It aims at satisfying the growing request of applications and facilities coming from professional users and emergency services. The system is at advanced level of standardization by ETSI (European Telecommunications Standards Institute) and is provided an European harmonized frequency band. This paper reports TETRA logical channels radio performance carried out by TETRASIM, a simulation software package, entirely developed at CSELT, which allows for the system radio chain modelling, according to the standard specifications. Performance analyses and results comparison are provided by taking into account the effects of co-channel interference, propagation models and mobile unit speed. The simulation results reported in this article were included in the ETR (ETSI Technical Report) "TETRA Designers' Guide Part 2: Traffic Aspects".
