39. Extended Performance Studies of Wi-Fi IEEE 802.11 A, B, G Laboratory Wep Point-to-Multipoint and Point-to-Point Links

Wireless communications using microwaves are increasingly important, such as Wi-Fi. Performance is a most fundamental issue, leading to more reliable and efficient communications. Security is equally very important. Laboratory measurements were performed on several performance aspects of Wi-Fi (IEEE 802.11a, b, g) WEP point-to-multipoint links. Our study contributes to performance evaluation of this technology, using available equipments (DAP-1522 access points from D-Link and WPC600N adapters from Linksys). New detailed results are presented and discussed, namely at OSI levels 4 and 7, from TCP, UDP and FTP experiments: TCP throughput, jitter, percentage datagram loss and FTP transfer rate. Comparisons are made to corresponding results obtained for WEP point-to-point and Open point-to-multipoint links. Conclusions are drawn about the comparative performance of the links.
