A wallpaper that blocks Wi-Fi signals is being developed to help protect people’s networks, whether at work or in the home.

Although the paper will stop skinflint neighbours from jumping on board your Wi-Fi signal, the wallpaper has been designed in such a way as to still enable both mobile phone signals and radio waves through.

The technology is the brainchild of French researchers at the Institut Polytechnique de Grenoble who have been working with the Centre Technique du Papier. It’s thought that as well as preventing strangers accessing people’s Wi-Fi networks, the wallpaper will be able to be used in hospitals and theatres to help block external sources.

Despite the research that has been invested in the technology, the development team claims the wallpaper will cost the “equivalent to a traditional mid-range wallpaper.” 

The wallpaper is being licensed to a Finnish manufacturer for production and it’s hope it will be available to buy from 2013.
