That's also why things like a fixed butler matrix really isn't very good. The goal is to be able to change the channel conditions sub second and maybe in the order of 10 milliseconds.

Also,

1) some 802.11g sender can't hear the 802.11b sender, so does not back off on
   using all the channels.

2) some 802.11g TV-over-wifi product intentionally does not back off, because
   that would break the TV signal.   This is happening 100m in the next
   household, and having a human (water bag) standing between the two
   households improves the situation.  So on each commercial break, the
   local wifi improves because the humans next door go to the washroom.

This means that the wifi speed/power selection gets all all confused,
several times per minute.
