Cellphone signal blocking via transparent window film
Are you yearning for a transparent window film that would block WiFi and cellphone frequencies from passing through it? If you're as paranoid as we are at some yokel sniffing out any kind of popular RF signal that is probably floating out the windows of your office building at this very moment, CPFilms has your answer. The defense department supplier's LLUmar Signal Defense film blocks those pesky radio rays from leaking outside those windows, giving your cellphone conversation peace of mind as well as those Bluetooth sync sessions and WPA-2 WiFi signals (heh). The film's been rolled out at over 200 federal facilities, so breathe a sigh of relief next time you're, you know, transmitting sensitive information in the Department of Treasury.[Via textually.org]
