French researchers have created a new product for people who feel like their wi-fi password just isn't giving them enough protection.
Engineers at the Grenoble Institute of Technology along with the Center Technique du Papier have designed a type of wallpaper that blocks cellular and wi-fi signals while letting through AM/FM radio waves and emergency transmissions, reports the Wall Street Journal.
The wallpaper is being marketed toward those looking to protect their private networks from outsiders, as well as to those who want to shield themselves from electromagnetic waves for health reasons. It will cost around the same price as mid-priced wallpaper.
The wallpaper needs to cover all surfaces, but can be covered by wallpaper or carpet. Developers are also working to design a clear version to cover windows.
