So, these are "closed"/private spaces (NOT "coffee shops" open to

Do you have an idea as to the mix of clients (laptops, phones,
appliances)?
And, how "saturated" the airspace is?

i have disabled 802.11b and nobody has complained.  The reason for
doing this is that some devices such as high-definition cameras
and screen sharing devices send large amounts of data using
multi-casting. If one WiFi recipient is connected very slowly
this uses up all the available WiFi bandwidth causing the whole
network to grind to a halt.

Yes.  OTOH, you can use multiple radios to move the slowpokes
out of the way.

Setting a minimum connection speed of 12MHz at 2.4GHz and 24MHz
at 5GHz is also useful and does not appear to cause any problems.

But, how much *higher* than that might you be able to go without
folks complaining about "equipment incompatibilities"?
