Multiplexing is an essential part in a communication system where multiple data streams are transmitted simultaneously through a single link. Multimedia data streams have special requirements that are hard to meet, especially on wireless systems. High bandwidth, small transmission delays and channel reliability are required for on-time data stream delivery and real time playback. Limited communication resources of wireless systems can be offset by the simultaneous use of multiple link layer technologies. Multiplexing data over a virtual channel, comprised of several radio sub-channels, can provide more bandwidth than each channel alone and improved quality of service (QoS).
