Tired of cheap neighbors elbowing in on your Wi-Fi signal? Then it’s time to do some redecorating!
Scientists from the institut polytechnique Grenoble INP and the Centre Technique du Papier have developed a novel new product so gratuitous, it almost seems necessary: a silver-crystal coated wallpaper that can block neighbours from freeloading off your Wi-Fi network. The silver crystals are arranged in such a way that they are able to block certain wireless frequencies, not least of which is the same frequency as a WiFI router.
As many before us have pointed out, one could always set up a password and windows will also allow your signal to sneak out despite your walls full of protection, but, hey, to each his or her own.
