Disabling Wireless Networks?

An Ominous Coward asks: "The University of Florida student chapter of ACM hosts a yearly programming competition for students throughout the state of Florida. It is based on the ACM International Collegiate Programming Contest, and for the past ten years has been very successful, currently drawing a crowd in the hundreds. However, this year was the first we had a problem with wireless networks. We doubt that cheating was the intention, as no one had SSID broadcasting turned off (as far as we know). Wireless networking gear is quite inexpensive now. And while we don't believe it affected the contest this year, we would like to take precautions for future contests. Is there any way to disable all wireless networking in an area about the size of a large lecture hall?"

Make everyone work in a shielded metal, enclosed cubicle and change the name of the contest to:
"Code in a Can"

What we really need to do is figure out how to disable wireless phones in an area about the size of a movie theatre or concert hall. Perhaps something slightly less lethal than a shotgun.

It's simple. Someone at OSConf in Toronto this year had no trouble taking out the entire WLAN with a laptop broadcasting in Ad-hoc mode on the same channel, same SSID.

Idiot. *mutter*
