Speaking on Deep Background, the Press Secretary whispered:
My company is investigating the use of wireless in a couple of our conference rooms. Aside from limiting the scope of reception with various directional antennae, does anyone have any suggestions or pointers for other ways to limit the propagation of signals (i.e. special shielding paint, panels or other wall coatings)?
As I told Andy, you need a "RayProof" or similar brand shielded conference room. This is Faraday Cage, with a tight-fighting door, etc.
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? Stupid pen-test tricks, instead of using an expensive WiFi scanner and cracking WEP; often you can collect better intelligence with a radio turned to the frequency used by wireless lapel mics used by executives during briefings.
