  1. Re: Anti-Wi-Fi Wallpaper on Anti-Wi-Fi Wallpaper · · Score: 2, Informative
    The real objective of this wallpaper (and competing paint and window film products) is to offer a low-cost method to provide TEMPEST protection to offices as an alternative to building a full skiff.

    This anti-WiFi wall paper is grossly overpriced. The same effect can be achieved using EMSEC's paint at a cost of about $3 per square foot (about $500 per gallon) or using ASTIC Signals Defense's SD1000, SD2000, or SD3000 series window films (about $15 to $30 per square feet installed; substantially more for the bullet proof glass version installed at US Embassies).

    See http://www.worldtechex.com/WorldTech/Browsing/frmC ategory.aspx?type=TECHNOLOGY&id=59&report-id=5 for more information about the ASTIC film.

    Both products block most RF frequencies, including the WiFi frequencies. The window film also blocks infrared threats(e.g. laser microphones) and UV threats (see the cambridge whitepaper on CRT threats).

    The paint essentially includes certain powdered metals, including copper, that block RF frequencies. The window film takes a blast-resistant film and uses a patented plasma sputtering process to place a thin layer of gold, silver, and other metals on the window film.

    The film is currently installed on a variety of buildings dealing with defense, homeland security, and intelligence in the Washington DC area. The EMSEC paint is State-Department controlled and requires a license for export. The ASTIC film can be exported to any country except those on the terror / bad company list.
