A simulation study of high-capacity cellular land-mobile radio-communication systems

Considers the problem of channel assignment in Land-Mobile Radiocommunication systems. The performance of the hybrid assignment scheme under various loading conditions is evaluated by using simulation results of channel that has a cellular mobile communications system forty cells with Erlang-B service. In addition the hybrid system is compared to the fixed and dynamic systems with respect to the maximum transmission per cell that each system can support, while having a call rejection rate of no more than 2 per cent. For the same cellular system the minimum number of necessary channels (in order to establish a given quality of service for various traffic load. A conclusion is offered per cell) is determined. A conclusion reached regarding the spectral efficiency of hybrid systems with respect to the fixed systems.
