The cdma2000 system is one of the strongest contenders for wireless data networking and provides next generation capacity. cdma2000 includes a sophisticated MAC feature which can concurrently support multiple data and voice services, thus effectively supporting very high data rates. In this article we study the performance of the MAC states defined in cdma2000. The proposed model has the capability of proportionally combining three parameters: channel utilization, waiting time and the saving in the signalling overhead. We study the effect of integrating a voice service and two data services with different characteristics. Since the true nature of the wireless data is yet unknown, we use a mix of Poisson distributed voice packets and Pareto distributed data packets. We derive analytical expressions and also obtain numerical evaluations to study the nature of the performance curve.
