Re: OT:Limiting number of Clients Per Access Point

lol ... this sure beats that stuff I wrote!

You still need to do a site survey to make sure your APs are not stepping on
each other. If you limit the number of users and then you have to deploy
additional APs to provide access ... then you have created another
challenge.

If you are using a controller, the controller would instruct each AP on the
channel and power settings ... so this is all good.
