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?"

This means that you can not use WLAN, cellphones and terrestrial TV/Radio. Is this really what you want?

Quoth the article:
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.

Quite usefull for setting test environments as well. In fact, extremely useful if you are working on cellular infrastructure or any other radio equipment that operates in a licensed band.

* FOOTNOTE: The American spelling** of aluminum is used here. If you are searching for more information on aluminum, be aware that the British spell it "aluminium" (and pronounce it accordingly).

** HISTORICAL FOOTNOTE: Aluminum was originally named "alumium" by Sir Humphry Davy, who later changed it to "aluminum" (perhaps in an attempt to make it more Latinized since alumen is Latin for alum, the aluminum compound that the name is derived from). The British (and allied English speakers) shortly thereafter changed the name once more, this time to "aluminium" so that it would again match the pattern of most other elements (helium, sodium, etc.), while the North Americans eventually decided to keep the second, slightly more traditional name. I predict that North Americans will adopt the more regular "-ium" spelling by the year 2050, prompting the British to start calling it "alumininium". At that point debate can begin on changing "platinum" to "platinium"
