Security-minded US decorators' supply outfit Force Field Wireless claims to have developed a DIY 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 report, 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".
