Hi,
I am facing this particular issue while providing Cisco unified Wireless solution to the customer. We are having CAPWAP 1252 APs controlled by WLC.
Scenario: 50 persons sitting in a hall with closely packed chairs using wireless simultaneously.
Wireless access provided by patch antenna at a height of 11m from the user. As one AP can server 25 users, 2 APs are placed with antenna directions facing the compact users. Each users gets very good signal from these two APs.
Whether there will be serious interference and client association issues in this scenario?
once one AP associates 25 clients, whether other 25 clients associate completely to other AP?
Please Suggest..
Regards,
Madhan kumar G

The most important is to make sure that the 2 APs are not on the same channel.
The best is to set the channels statically. You have the choice between 1,6 and 11 so best chose 1 for an AP and 11 for the other to keep some separation.
With 25 clients per APs, yes there will be collisions and yes there will be interference. Imagine you plug 25 PCs into a 100Mbps hub, it's not going to be pretty and there is nothing to do about it :-)
The APs cannot do anything to "load balance" the clients (at least in IOS, WLC can try to do its best but is still not the one deciding). The clients decide where they associate and if the client drivers are stupid and make bad decisions ... you also can't help it :-)

Hi Nicolas,
I agree with you completely. Thanks for your suggestions.

Also, your APs got two types of radios: 802.11a and 802.11b. It could also help a bit if 802.11a is enabled.
