Wi-Fi Blocking Paint
Most people who want to protect their wireless signal from outsiders simply turn on the security in their wireless router, but now there’s another option that will keep even the best hacker out: anti-wi-fi paint.
The University of Tokyo has developed a special paint that blocks radio frequencies in higher spectra where Wi-Fi and other higher-bandwidth communications occur. If you put it on the walls of your home, it will keep the signal from passing through, effectively stopping anyone outside your house from being able to access it. This unique paint — the first of its kind — mixes aluminum-iron oxide particles with ordinary paint. That’s the “special sauce.”
According to Yahoo! Tech, movie theaters are also interested in this new paint. A frequent problem in theaters is that pesky cell phone which people “forget” to put on silent during the film. Theater owners can’t use cell phone jammers because that’s illegal, but passive materials (like paint) that block signals are not. Since the anti Wi-Fi paint can also block lower-frequency signals used by cell phones, it could put an end to those annoying calls and ring tones during your next movie. Cool, huh?
