Investigate the Throughput Performance of IEEE802.11

Abstract

The purpose of this study is to analyze the indoor Wi-Fi signal throughput performance, using IEEE802.11g radio interface at 2.4. GHz ISM band. This study focuses indoor signal measurement and prediction, which had been done at UniKL BMI by applying line-of-sight and non-line-of-sight environments. Indoor scenario usually more complicated due to moving people, which rapidly changing environment. Signal were monitored using a fixed CISCO LINKSYS WRT160N wireless-n type access point that connected with server and java application software; jperf software runs on portable computer. The signal propagation mechanisms like diffraction, reflection also determine the signal behaviour and it needs to be considered to predict the signal strength. Propagation mechanisms occur when there is an obstruction between the transmitter and the receiver.
