Wifi Blocking Wallpaper

Researchers at the Grenoble Institute of Technology have developed wallpaper that’s designed to trap Wi-Fi signals without interfering with radio or cellphone signals. The wallpaper contains conductive ink containing silver crystals which prevents the wifi signal from penetrating the wallpaper. Though the wifi blocking wallpaper is still in its prototype phase, Finnish based Ahlstrom has been granted exclusive rights to manufacture the wallpaper which should be hitting the shelves some time in 2013.
