 en Multiple Users Round Trip Time Models in IEEE 802.11b WLANS


The dependence of Round Trip Time (RTT) on Signal to Noise Ratio (SNR) for multiple users in an IEEE 802.11b Wireless Local Area Network (WLAN) was studied in this work. Data collected in open corridor, small offices and free space environments in an infrastructure based network (where different quality of service traffic were continuously being sent by multiple users) was used to develop and validate Multiple User RTT models predicted from computed SNR.The models were also compared with single user models earlier developed. The tests results show that for multiple users on the network, RTT can be predicted from the computed SNR with reasonable accuracy as the models passed the F and T test at 0.1% level of significance and RMS errors of less than 867.378214ms were observed. During network design and installation, these models provide useful tools that can enable IEEE 802.11b WLAN installers to make fast and better informed RTT decisions.
