Wireless integrated services IP LAN in 5GHZ U-NII band

by Ho, Duncan

In this work, we present a High-Speed Medium Access Control (MAC) Protocol with Distributed Weighted Fair Queueing for Wreless Lod Area Networks. It provides Integrated SeMces for Intemet Protocol (Il?) with Quality of SeMce (QoS) support. We use the QoS fiarnework proposed by the Internet Engineering Task Force (IETF). Time Division Duplexing (TDD) is used for medium access and Self-Clocked Fair Queueing is used for scheduhg. The sensitivity of the performance of the srstem to various system parameters such as the nurnber of remote stations, the range of the system and the modem tum-around tirne are studied. Moreover, Reed- Solomon coding is used in conjunction with Automatic Request (ARQ) to combat Channel irnpairrnents. The packet headers are designed to produce high efficiency . The theoretical throughput bound and the optimum capsule size of the system are denved. Simulation results and discussions are presented.
