Terminal Centric Optimisation for the Wireless Local Area

There is growing interest within industry and standardisation bodies to permit wireless local area networks to utilise the scarce radio resources more efficiently and intelligently. One approach is to increase the physical layer data rate and exploit multi-path and spatial diversity using multi antenna systems, the other, and complementary, approach is to use more intelligent dynamic channel and mode selection. Both approaches are inter-related, but in this paper we focus on techniques for the latter. In particular we address the dynamic channel and mode selection problem from a terminal point of view and have implemented a solution that provides significant performance enhancements over conventional techniques when applied to existing wireless local area networks.
