Block Wi-Fi Pilferers With Anti-Wireless Wallpaper

Locking down a home Wi-Fi network securely ought to be on everyone’s list of Tech 101 tasks. And yet, an awful lot of people find it to be too big of a hassle to memorize the passkey or share a random 13-letter string with visiting friends, so they leave it open. Others have an unbelievably easy-to-guess password. (If you’re using your own last name, pet name or the same words on your vanity license plate, why even bother?)

Soon, though, there’ll be an easier solution — just slap on some Wifi-blocking wallpaper, to keep your signal contained inside!

Developed by institut polytechnique Grenoble INP and the Centre Technique du Papier, this special wallpaper features a pattern of embedded silver particles that are arranged (or “tuned”) to block specific wireless frequencies, like the ones used by your router. (And, you’ll be happy to know, this particular one shouldn’t interfere with any cellular signals.) Best part? When it becomes available next year, it’s not going to cost an arm and a leg. Although there’s no official price announced yet, word has it that it’ll sell for roughly the same as regular wallpaper.

The only issue is the aesthetics. Scratch that: If you’re not down with snowflakes, you could always paint over it or attach some fabric. The real peskiness is the application. You’d have to wallpaper the ceiling, floor and walls (yes, including the windows) to seal it up tight. Now that’s a whole lot of surface to cover. But the company is reportedly working on a transparent, ultra-thin version, so if you like the concept of this, keep your eyes peeled for future developments.

Do you lock down your home Wi-Fi network? If not, would you consider using something like this, or would you still leave it open? Weigh in.
