First generation wireless systems, which primarily provide analog voice service, are widely in use worldwide. Second generation systems support digital voice/data traffic; some of these systems are already deployed or undergoing deployment. Third generation wireless networks will ultimately carry multimedia traffic that are characterized by combination of different informaion streams of diverse nature (e.g., voice, video, image, data). Some of the salient features of multimedia applications are high speed and changing bit rates (periodic and bursty arrivals), several virtual connections over the same access, synchronization of different information streams, and various service/deliveIy requirements (QoS).
