Are
your neighbors tired of you stealing their unsecured wi-fi? Here’s an
expensive alternative to providing password protection. The Grenoble
Institut Polytechnique and its research partners have developed
wallpaper that blocks wi-fi transmissions:
The wallpaper can block Wi-Fi signals in the 2.45 – 5.5
GHz range, while simultaneously allowing television, FM radio, and
mobile phone signals to pass through its surface. Metapaper can be
applied to a variety of surfaces including concrete, brick and plaster,
and won’t be affected by decorative additions such as a layer of common
house paint. No announcement has been made as to when this product might
reach the U.S. market.
So far, the wallpaper costs $800 for 10 square feet.
