Force Field Wireless claims to have developed a solution to the international menace of marauding geek wardrivers – DefendAir paint "laced with copper and aluminum fibers that form an electromagnetic shield, blocking most radio waves and protecting wireless networks". According to a South Florida Sun Sentinel article, one coat of the water-based paint "shields Wi-Fi, WiMax and Bluetooth networks operating at frequencies from 100 megahertz to 2.4 gigahertz", while two or three applications are "good for networks operating at up to five gigahertz".
There are some downsides as Force Field Wireless admits that "radio waves find leaks" andthe company asks users to be aware that the product "must be applied selectively" otherwise it "might hinder the performance of radios, televisions and cell phones". Although DefendAir is available only in grey, it can be used as a primer, so those who require wireless peace of mind plus bold fashion statement can cover it up quite nicely. And I thought the aluminum foil I have all over my house would be enough. Hmmmmm.
