I have been looking into the Cisco Aironet solution recently for a project I'm working on. They seem to have some great security features, if you want to take the time to configure it. Oh, another caveat is that you have to use Cisco's wireless adapter as well, otherwise, good ol' WEP

There is an adage in the Wireless industry. If it will hold water it will hold RF Energy. Unfortunately this is true and the only method by which you can prevent the egress of 2.4 GHz signals from a defined area is by the use of a faraday cage and since the wavelength is short you need a very

Speaking on Deep Background, the Press Secretary whispered: Uhm, dumb question. If it is that important, why are you using wireless at all? Why not install a cheap switch/hub in the middle of the conference table and let people plug a patch cord from the hub to their laptops? I have to

Unless you are looking to isolate a small box for such purposes as testing RF devices, I would not use a shielding technique to limit access to your wireless network. Containing 2.4GHz signals within a room of any reasonable size is extremely difficult. You would probably have to cover it with

Planning on limiting signal using a physical mechanism of some sort's just a little too scifi to be useful. It's too much effort to shield the room itself, but you might want to try making the inverse square law work for you by shielding all of the wireless antennae so that the signal is too
