Performance Studies of Wi-Fi IEEE 802.11 A,G WPA Point-to-Multipoint 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, g) WPA point-to-multipoint links. The authors' 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.
