Reducing transmit power should reduce the range devices can connect at
particular data rates. You can remove support of some of the lower
data rates so that as devices throttle down, they'll look for "better"
APs more quickly instead of holding onto APs at 12, 9, 6mbps, etc.
Keep in mind that it should be each channel, not AP/radio, that should
be designed to support a particular number of devices.

Out of interest what level of transmission did you lower your APs
to? I've found changing transmit power has very little effect within
a single "open-plan" room, it only really seems to have much effect
when the signal hits obstacles such as walls, and shelves of books
etc.
Many Thanks

Our team designed our system to accommodate large numbers of people in
one area by installing a greater density of AP's, lowering the AP
transmit power, turning off the slower B transmit rates, and
encouraging
users to utilize 5Ghz N.

Hi
We have a small installation with about 40 Cisco lwap's (b/g)
running on
a Cisco 4402. I've just gotten a request from a group that wants to
run
50+ clients in one room. The last time we tried that about 4 years
ago,
it was a disaster. We had fat AP's at the time. There were a lot of
Mac's, and they kept grabbing each other instead of the AP's. Ugh.
How
do folks handle this now? With my current system can I just throw a
couple more AP's in the room and let them have at it?
Thanks
John
