In recent years there has been a move to increase the data capabilities of TErrestrial Trunked Radio (TETRA) so as to provide secure broadband data capabilities. An initial enhancement (TETRA Enhanced Data Service, TEDS) has been agreed but there is a need to access additional spectrum. An investigation was carried out by European Telecommunications Standards Institute (ETSI) has concluded that a single standardised frequency band cannot be agreed and the concept of a tuning range for enhanced TETRA services can be deployed is gaining acceptance. In addition to needing flexibility in frequency, 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 and deliver true broadband data service while simultaneously support the original and enhanced TETRA services.
