Wi-Fi Blocking Wallpaper

Tired of your neighbors stealing your Wi-Fi – THEN PUT A WEP KEY ON IT, GOOBER!  Okay, even if you have it encrypted, people could still bogart or snoop.  This wallpaper could stop all that. Researchers at France’s Institut Polytechnique de Grenoble have worked with the Centre Technique du Papier to develop Wi-Fi-blocking wallpaper. The product, also known as metapaper, claims to selectively filter, reduce or reflect electromagnetic waves.

Metapaper not only protects against intruders stealing Wi-Fi from buildings, but also ensures that signals inside a building are more secure and stronger, the group says. Benefits include data security for companies or people that need dependable Wi-Fi. The wallpaper can also be used to create quieter spaces for places like hospitals and movie theaters.

The high-tech paper does, however, allow FM radio waves and emergency frequencies to pass through. The paper, which has a snowflake pattern on it but can be covered up by traditional wallpaper, is made from renewable resources and is recyclable, according to the Centre Technique du Papier.

While this is cool, we aren’t 100% sure how it would work.  You couldn’t wallpaper a whole room, just the outside walls of your place.  Still, it’s a cool concept! The paper is not yet commercially available because it is still in the industrialization phase.  We will keep you posted as to when/where you can buy some.
