Smart antenna is suggested to be used in future generation wireless and mobile networks to provide service with high capacity and quality. In this paper, we propose an analytical model for a novel multimedia wireless and mobile networks using smart antennas. The smart antenna in the proposed system provides space division multiple access (SDMA) scheme in which channels can be reused in one cell and system capacity is improved dramatically. In this paper, two kinds of multimedia services, real-time voice service and non-real-time data service, are taken into consideration. In the proposed system model, channels are divided into four parts which will serve different types of requests and calls. In this way, service quality is guaranteed for real-time voice service at the cost of the tolerable quality decrease for non-real-time data service. The system is analyzed by a four-dimensional Markov chain. Blocking probabilities of originating calls and handoff requests are obtained from our formulas. As we expect, system capacity and performance are highly improved by employing smart antennas.
