Laboratory performance comparison of IEEE 802.11 b, g point-to-point links: a case study

The importance of wireless communications, involving electronic devices, has been growing. Performance is a very important issue. Laboratory measurements are made about several performance aspects of Wi-Fi IEEE 802.11 b, g point-to-point links. A contribution is given to performance evaluation of this technology, using two types of access points from Enterasys Networks (RBTR2 and RBT-4102), and wireless routers from Linksys (WRT54GL). 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.Laboratory
