Stealth-Based Wallpaper Stops Wi-Fi Signals Dead

from the no-further... dept

One of the many issues companies bring up in explaining why they won't install Wi-Fi wireless networks is the "bleeding" issue: the wireless "bleeds" beyond the walls of their building and out into the parking lot, where some creative hackers might be able to get access. Well, if someone's got a problem, someone else is likely to come along and solve it. British defense contractor BAE has taken some of that stealth bomber material they had lying around and put it up on the walls and discovered it blocks Wi-Fi. In other words, companies could put up this wallpaper and stop the Wi-Fi from bleeding out beyond the walls. Of course, I would imagine that stealth wallpaper doesn't come cheap.

    I believe it was buck henry you are thinking of, or not thinking of!! :)) The use I see for it is in my server rooms where stray radio signals can cause strange server issues. Epecially since now everyone and their mother has the motorola walkabout radios.

    Not now. But when tooling costs are paid for, the price of these things come down. Not a bad place to look into investing. Better hope they don't patent the idea. heh heh...

    How about incoming signals?

    I imagine this would also kill things like cell phone signals coming in too. Cute.

    Of course it’s possible to block transmissions. There’s a whole industry out there which has been providing such solutions for decades. You can even buy ‘radio proof’ glass form Pilkington. Got to hand to BAE in their attempt to flog off some left over gear to punters - who don’t know any different. Like selling ‘oxygen free copper’ speaker cables to hi-fi buffs.
