Stealth wallpaper could keep WLANs secure
UK defence contractor BAE Systems has developed a stealth wallpaper to beat electronic eavesdropping on company Wi-Fi networks.
The company has produced panels using the technology to produce a screen that will prevent outsiders from listening in on companies' Wi-Fi traffic but let other radio and mobile phone traffic get through.
The FSS (Frequency Selective Surface) panels are made in the same way as printed circuit boards - layers of copper on Kapton polymer - and used on stealth bombers and fighter jets.
