This new wallpaper was developed by the Institute of Integrated Polytechnics in Grenoble, France, and the French Paper Technology Center. The material is a special kind of silver crystal that can limit the Wi-Fi signal within a certain range. Since it only acts on signals within a fixed frequency, it does not affect the signal.
Researcher Pierre Lemet Aoge of the Polytechnic Institute of Technology in Grenoble said that wireless networks can easily be breached. If wallpapers are decorated on the wall of an office or apartment, it can guarantee that wireless networks will not be stolen. Although most wireless network users will set passwords, they are sometimes “dumped†by their neighbors and affect their own network speed. This type of wallpaper can further ensure the security of wireless networks.
However, this type of product is not the first time ever. A few years ago, British Aerospace Systems once introduced a similar product, but at the time it was selling at a high price. The price of 10 square feet (about 1 square meter) of wallpaper was about 800 US dollars (about 5038 yuan).
In contrast, the price of this new type of wallpaper developed by French scientists is much more reasonable, and it is only slightly more expensive than the medium-priced ordinary wallpaper on the market. Moreover, it can be attached to the surface of many materials, including concrete, bricks and lime layers, to further prevent the leakage of Wi-Fi signals and improve the security of wireless networks.
