Multiplexing Technique for All-IP 4G Heterogeneous Network

Fourth generation mobile systems and services will mainly be characterized by a horizontal communication model, where different access technologies such as cellular, cordless, wireless local area network, short-range connectivity, and wired systems will be combined on a common platform to complement each other optimally for different service requirements and radio environments. To access different wireless networks, multimode user terminals are essential. The most promising way of implementing multimodal user terminals are to adopt the software radio approach. In this article, the authors find the complexity through establishing 4G Heterogeneous network and discuss over the recently developed multiplexing technique to access all IP based networks.
