TErrestrial Trunked Radio (TETRA) offers capabilities equivalent to the second generation of mobile phones with voice and limited data capabilities. TETRA needs to evolve to satisfy increasing user demand for new services and facilities as well as gleaning the benefits of new technology. An initial enhancement (TETRA Enhanced Data Service, TEDS) has been agreed. The enhanced TETRA services allows for more flexibility in the communication modes used, so as to provide adaptability in applications. We propose that it is possible to deploy Software Defined Radio (SDR) technologies into the basestation to economically provide this level of flexibility and to further extend the capability of TETRA services by deploying a WiMAX channel into the proposed TETRA tuning range. Thus delivering true broadband data service while simultaneously supporting the original and enhanced TETRA services.
