You’re not truly alone in the privacy of your home until you’ve plastered the walls with silver snowflake-patterned anti wi-fi wallpaper from Finland. ITProPortal reports:
A new type of wallpaper, which has been developed by scientists from the “institut polytechnique Grenoble INP” and the “Centre Technique du Papier”, will go on sale in 2013 after a Finnish firm, Ahlstrom acquired the license.
What looks like a bog standard wallpaper roll actually contains silver particles that allows it to filter out up to three different frequencies simultaneously.
Other than preventing hackers from penetrating your network, the Anti Wi-Fi wallpaper could be useful in hospitals and anywhere where Wi-Fi signals could be considered as harmful.
