Wallpaper Prevents Wi-Fi Data Leaks
The "paper", which is made of copper and plastic, keeps wireless signals inside buildings while allowing cellular signals to pass through
BAE Systems has developed wallpaper that helps keep companies' wireless networks secure. The "paper", which is made of copper and plastic, keeps wireless signals inside buildings while allowing cellular signals to pass through. Previous methods of securing wireless networks that used aluminum-lined walls and windows made of signal canceling glass trapped cellular signals as well. Although the wallpaper isn't for sale yet, BAE estimates it will cost as little as $300 to cover one floor of an office building with the wallpaper.
