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.
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

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.

Re: wifi blocker
Yeah, but you don't need windows if you have invisible walls.
