Nah, the analysis doesn't take into account the delay inherent in 802.11b's Distributed Coordination Function.


Back of the envelope calculations would show that using G.711 A-Law encoded audio transmitted in 20 ms blocks (say 160bytes of audio per frame) at 11Mbps would give a maximum of 12 VoIP calls possible and this still doesn't take into account a noisy channel which increases the amount of time wasted in the DCF.
