Abstract

Wireless local area networks (WLANs) supporting broadband multimedia communication are being developed and standardized around the world. The HIPERLAN/2, 802.11a and HiSWANa standards provide channel adaptive data rates between 6 and 54 Mbps in the 5GHz radio band. The link adaptation mechanism is not specified in the standards. In this paper the performance of the HIPERLAN/2 system is evaluated in terms of throughput in a range of test channels with different degrees of frequency selectivity. On this basis, the impact of frequency selectivity on system performance is evaluated and the implications for the design of a link adaptation strategy are discussed. The issue of link adaptation for time bounded applications is also considered. The resulting conclusions are generally applicable to all three 5 GHz WLAN standards
