Does Wi-Fi Proof Wallpaper Come in Pretty Paisley Patterns?
"British boffins have developed wallpaper that blocks Wi-Fi traffic but still allows other wireless transmissions to pass through in a bid to prevent unauthorised access to sensitive data via the WLAN. Developed by UK defence company BAE Systems, the wallpaper uses Frequency Selective Surface (FSS) sheeting, a material more commonly found slapped on military aircraft, naval vessels and radar antennae, New Scientist reports. In this case, the FSS material is manufactured to absorb signals in the 2.4GHz and 5GHz frequency bands used by 802.11a, b and g equipment. Other frequencies, such as the 1800MHz band used by GSM networks, are not blocked."
Ooooookay. That's one of those ideas that seems daft at first, but make sense the more you think about it. Or at least it did for me anyway. Just think, with all the energy from those radio waves bouncing round your office, the companies deploying this won't need to spend much money on heating bills. :lol: So, Wi-Fi warping wallpaper: will you wrap your walls with it to withstand WLAN wire(less)tapping? :wink:

If you have to ask the price.....
My guess is that the cost will be jaw dropping, certainly for enough to cover an office. I also doubt you can get hold of this easily - IF it is going to be commercially available. Apart from that, no problem. :wink:

Hrm, personally, not going to want this for my place. One benefit of wifi is working outside. On a personal level I'm comfortable with basic encryption and/or MAC filtering. Right now, I use neither...anyone trying to find a file on my system is going to be disappointed when they find the important ones are protected, but I don't want to block some poor guy trying to get his email...

This is stupid, because then the WiFi wouldn't get to the rest of your house, if the room where the router is, is covered with the Anti-WiFi Wallpaper. :roll:

Then how about windows etc? Don't tell me office doesn't have windows? Surely the wifi signal can escape from there rite?

I think it's meant for the outer walls between the street and office. Newbie2 has a point though, windows is an escape.

Does it bounce or does it block? If it bounces, it should help interior signal significantly.
Windows can be partially protected by embedding a metal mesh into the glass. I suspect a thin layer of metal (i.e. gold?) will do as well. If you're high up on the 60th floor, you won't have much to worry about in terms of an open window.

Don't be so sure, I've heard of War Driving Window Washers... :mrgreen:

Better that way, anyway. Aside from the multipath that would result in reflection, an inward reflecting chamber at 2.4GHz is esentially a microwave oven.
