Throughput performance of WLANs operating at 5 GHz based on link simulations with real and statistical channels

At present, wireless local area networks (WLANs) supporting broadband multimedia communication are being developed and standardized in the 5 GHz band. Two such standards are HIPERLAN/2, defined by ETSI BRAN, and the IEEE 802.11a. This paper presents the throughput performances of the two standards based on link simulations with real and statistical channels. Physical layer performance results are presented for real channel measurements and the impact of sectorised antennas at the access point is given for HIPERLAN/2.
