An increase in mobile devices and laptops has led to WiFi service being available everywhere, be it at cafés, libraries, malls and other public places. The ability to connect so easily to any WiFi network creates concern for hacking and stealing of private information. Sure private properties can block access to their WiFi to unknown users by creating a password for their network. But what about public properties that allow their customers to access the Internet?
These places must either create a password and let their customers know, or make access public. If a company were choose the later option, they may want to look into new wallpaper technology developed by Institut Polytechnique de Grenoble (INP), which will block WiFi signals being broadcast outside of the network’s area. This new wallpaper means having secure WiFi network, while still being able to use radio and mobile phone services. It also utilizes dual technology, keeping the WiFi signal inside the network’s area, as well as blocking outside signals from entering the space, thus eliminating possible security breaches. The wallpaper works by blocking electromagnetic frequencies. Its blocking capabilities are not hindered if businesses or homeowners want to place other decorative wallpapers to change the original silver color. Offices nowadays must be stylish, no?
