Anti-WiFi wallpaper that lets cellular and radio through
French researchers have developed a special wallpaper that can block WiFi signals, preventing them from being broadcast beyond the confines of an office or apartment. Unlike other signal-blocking technologies, this anti-WiFi wallpaper only blocks a select set of frequencies used by wireless LANs, and allows cellular phones and other radio waves through. the wallpaper should be available for sale in 2013.
