A high quality VoIP channel only needs 64 Kbps (and in reality you can

unlikely to have much knock effect on a single VoIP channel.

The many Mbps is the burst rate once the device has found a clear bit of
air time.Â* The latency is waiting for that clear air time.Â* Also VoIP
bursts are very short, but there are many of them.Â* They need to find
clear air time 50 times a second, and they need to do so within a few
milliseconds, each time.

In any case, I'm not going just on the theory.Â* It is empirically
reported by people who have tried it that Wifi doesn't work well for
real time voice.

I also gave an empirical example - three VoIP handsets, one wifi bridge,
no complaints on voice quality.

Now depending on the loads on other loads on the wifi, and the number of
other in range access points sharing the same spectrum, I am quite
prepared to accept you might have difficulties. However its not a given
that you will get a poor experience with VoIP over wifi, so if its easy
to do, its worth trying.
