RF-Blocking Wallpaper
spitefulcrow writes "Silicon.com is reporting on a new application for RF-absorbing materials: Wallpaper that blocks Wi-Fi. BAE, the British defense contractor, has announced that the same material used to foil radar by stealth bombers can be used to selectively block certain frequencies and prevent wireless networking signals from entering or exiting a building. Is this the next take on lining the walls with lead?"
We hear a lot about the need for tinfoil hats - it looks like that problem just got a modern-day solution.
Bet it kills mobile phones too, though.
I have been a user for about 10 years. This ends Feb 2014. The site's been ruined. I'm off. Dice, FU
Tin foil is so, well, passe. Some bright stripes, or maybe some flowers, would be soooo chic.
Generally, bash is superior to python in those environments where python is not installed.
if the people don't care about others movie experience enough to turn the mobile off when they clearly should, what makes you think they'll act properly when you try to force them? imagine running around the theatre and yelling "CAN YOU HEAR ME NOW??". It's a people problem, not a tehcnological one(is speeding or drunk driving a technological problem? no, it's a problem of people acting like assholes).
anyways if you had read the article you'd notice that this material can be used to block ONLY wifi frequencies(I'm assuming 2.4ghz), whilst letting other rf pass(including mobile phone frequencies).
world was created 5 seconds before this post as it is.
Now if Think Geek will only sell Tin Foils hats lined with this stuff, we will be all set.
I make my face look like this and concerned words come out.
Great Idea! And when there is a fire in a building that has this, and it blocks all Emergency Radio communication so that Firefighters lives are in danger, we can all thank the far sighted users of this miracle wallpaper.
So lets put this in theatres, and hospitals, and other places where the publics safety and welfare is not as important as blocking anoying cell phones and protecting wifi data (that wep/wpa and a prudent semi-inteligent network admin could protect).
Products like this have a place in small uses but any large use would be a safety hazard that isn't worth the risk.
