I also have a Faraday cage around my WiFi router. WiFi routers are seriously overpowered and pump out gobs of RF, I personally verified this at home with RF meter, the Faraday cage kills it, and the WiFi still works.

On a lighter note, the very 1st time I saw a man using Bluetooth headphones I was sitting at a Starbucks/Safeway atrium when the guy walked in stopped dead in his tracks in the middle of the walkway just past the doors and was talking to himself out loud and I thought he was a well dressed escapee from a mental ward.
The coffee was undrinkable but it was always entertaining, like watching people order a 20oz latte, putting it on the roof of their car, driving off, and then coming right back to buy another one ;]
