Performance studies of 802.11g for various AP configuration and placement

Using indoor radio propagation measurements, the impact of access point (AP) configuration as well as placement on throughput of IEEE 802.11g (“802.11g”) wireless local area networks (WLANs) is investigated. By using a pair of wireless laptops and APs we conducted several experiments involving 802.11g computer links, which were carried out in a controlled environment at AUT University within the School of Computing and Mathematical Sciences office building. The AP configuration and placement is found to have the significant effect on the link throughput of 802.11g. Results obtained show that a different throughput performance be achieved with a different AP configuration and placement, the resulting throughput variation is found to be significant. By using an appropriate AP configuration and placement, an optimum system performance can be achieved.
