I don't know the total bandwidth figures for G off the top of my head, I'm
guessing around 800KB/sec. (B is around 400-450KB/sec.

You can liken AP's to old Hubs, shared bandwidth, and when they begin to
come under load performance worsens exponentially.

You can find that the person with the weakest signal will get even worse
bandwidth as everyone else will go over the top of them.

What sort of apps will be using this bandwidth?
