It would be interesting to run a spectrum analysis as well as load analysis on the APs.

To piggy back on Nicks statment. If you have AirMagnet i would check wifi channel utilzation. Also also 16 aps for 700 students, is that right. all of them are on wifi ? thats a bit much..

Just to add to everyone's post.. That is a lot of users for that amount of AP's and I can see why they have issues.

Can you see the utilization on the switchport the AP's are connected to or even the utilization from that building to your core? If you have lightweight AP's and WCS, you should also be able to see the utilization at a given time on each AP. I have worked on College dorms and apartment units and we have installed much more than that. I would have to guess maybe 25 or less students per AP. this was also due to attenuation. They do love their gaming systems though:)

ANother thing ... 16 WAPs?  I hope you are using only the 802.11a radio.
