Comparative Performance Studies of Wi-Fi IEEE 802.11 A, G Laboratory Point-to-Point Links

The importance of wireless communications has been growing. Performance is a very relevant issue, leading to more reliable and efficient communications. Laboratory measurements are made about several performance aspects of Wi-Fi (IEEE 802.11 a, g) point-to-point links. A contribution is given to performance evaluation of this technology, using available access points from Enterasys Networks. 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. Conclusions are drawn about the comparative performance of the links.
