Effect of Free Bandwidth on VoIP Performance in 802.11b WLAN Networks

Overview In this paper the authors experimentally study the relationship between bandwidth utilization in the wireless LAN and the quality of VoIP calls transmitted over the wireless medium. Specifically the authors evaluate how the amount of free bandwidth decreases as the number of calls increases and how this influences transmission impairments (i.e. delay, loss, and jitter) and thus degrades call quality and show that the amount of free bandwidth is a good indicator for predicting VoIP call quality.
