Abstract

Northern Telecom has successfully demonstrated the operation of a time division multiple access (TDMA) demonstration system using six channels multiplexed onto a single RF carrier frequency and utilizing a nominal RF bandwidth of 30 kHz. This matches the analog FM bandwidth, and permits simple transition from existing RF channel assignments to digital channels. The architecture and operation of the digital cellular demonstration system are described. The demonstrations included two digital mobile units making simultaneous use of the system in either or both of two cells. Call set-up, hand-off, and disconnect were demonstrated by interfacing to the DMS-MTX, a standard configuration cellular switching system. Subscriber data transmission over the mobile radio channel at a rate of 9.6 kbit/s was also included as part of the demonstrations
