Cellphone signals violating tribal lands in Canada?
When it comes to the modern design of cellular-based mobile systems, cellphone tower and handset signals transmit a full 360 degrees without regard for territory or political boundaries. Therein lies the problem; some Canadian tribes are a little miffed that cellular signals from nearby Manitoba Telecom Services are crossing into their land, over their water and into their airspace. Apparently, airspace is being likened to water usage in the logic for this argument. As these reserves and territories are being violated in some form (that's up for debate, we guess), several Manitoba chiefs are in the process of negotiating revenue-sharing agreements for these signals now. If they fall through, though, there's always signal-blocking paint.
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]
