Can Faraday Cages Tame Wi-Fi? 145
mrraven writes "An article at TechWorld discusses the increased need for wireless network security. One possible solution to this problem is the use of building-wide Faraday cages to block the wireless signal from 'leaking'." From the article: "Small installations of RF shielding don't have to be expensive, and the basic concept of a Faraday cage can be extended to all kinds of small everyday objects. Leather wallets sandwiched with a conductive RF-shielding layer can prevent RFID scanners from reading personal information implanted in everything from RFID-enabled access control cards to some credit cards; they're widely available for as little as US$15. For those favoring a more DIY route, several Web sites have information on how to make an RFID-blocking wallet with duct tape and aluminum foil."

I think the idea is to keep the voices from leaking out.

BTW, I can just image the "scare-the-consumer" infomercials for those. "Anyone just walking by can steal your entire life! Stop them now with our high-tech disposable Super-TF-Wallet! Just 3 easy payments of $19.95 and you...."

And WiFi? No way! I have 3 access points (One in attic, one in basement, one on the same floor as the PC using it (10' away on the other side of a wall) and do you think I can get a reliable signal? Hell no, but if I am in my car I can pick it up 2 blocks away.
My wifes old 900MHz phone works fine, my new 5.8GHz phone? it'll only work if I stay in the same room as the base-station and the people can only hear me when I yell.
If I try using 802.11a, I get good results (despite my wifes phone and 2 microwave ovens in the house), my CRAP (Completly Ridiculous Assinine Pet) theory is that the lower frequency passes through the super-human drywall that my house is made of. But to compete with that theory I can't understand why a Nerf-ball is able to dent the wall.
Time to move I guess.
