Transparent Sheet Blocks Mobile Phone Signals

Cellular News reports on a new transparent film for windows which claims it can block or seriously degrade radio signal penetration.

"While aimed at companies seeking to secure internal wireless communications, doubtless some organisations will investigate the possibility of using this to block mobile phone signals.

... Developed in conjunction with the U.S. Department of Defense and CPFilms' technology partner, ASTIC Signals Defenses, the film uses a patented combination of metal and metal oxide layers to reduce the signal strength across the entire electromagnetic spectrum. "
