VoIP Capacity over Multiple IEEE 802.11 WLANs

– It is well known that IEEE 802.11 WLAN is highly inefficient for transporting voice data. For example, if one simply takes the data rate of 802.11b, 11Mbps, and divide it by two times 13.2Kbps (the bit rate of a typical voice stream in one direction), one comes to the conclusion that more than 400 voice sessions can be supported in an 802.11b WLAN. As shown in previous work, it turns out that at most 12 sessions can be supported due to various header and protocol overheads
