Wallpaper that blocks Wi-Fi signals  - PCstats.com Wallpaper that blocks Wi-Fi signals
Thu, August 05 2004 | 12:48PM | PermaLink Feedback?
type of wallpaper that prevents Wi-Fi signals escaping from a building without blocking mobile phone signals has been developed by a British defence contractor. The technology is designed to stop outsiders gaining access to a secure network by using Wi-Fi networks casually set up by workers at the office. It is the work of moments for an employee to connect a paperback-sized Wi-Fi base station to a company network. That person can then wander around the office with their laptop while remaining wirelessly connected to the internet. But it is also the work of moments then for an outsider to breach that company's computer security using the Wi-Fi connection. Unless the Wi-Fi base station is protected by security measures that most amateur users would not bother to set up, it gives anyone up to 100 metres away the chance to bypass the corporate firewall and wirelessly hack straight into the network. Until now, the only way to ensure people are not illicitly gaining access to company secrets has been to turn offices into a signal-proof "Faraday cage", by lining the walls with aluminium foil, and using glass that absorbs radio waves in the windows. This ensures all electromagnetic emissions are absorbed, but it also means that no one can use a cellphone in the building.
