Traffic performance characterisation of a personal radiocommunication system

A recently proposed personal radiocommunication system is described. The system, which is intended to provide a low-cost mobile radiotelephone service, employs a novel radio link architecture that combines features of centralised and distributed control. Consumers would typically purchase two transceivers, one for a vehicle, the other for the home. The latter unit interfaces with the public switched telephone network through an ordinary modular coupling. Two types of payload radio channels are used, local direct and repeater. Users gain access to these channels by successfully completing a specified exchange of command messages on supervisory channels used in a random access mode. An analytical model was developed to characterise traffic performance and a simulation of the proposed system's traffic characteristics was undertaken. Both are described in the paper. Predicted performance characteristics are presented.
