content: This way my thought. If something is a matter of "national security", there is clearly a bigger agenda afoot. The government clearly wants to use the technology to their advantage. I don't believe the other comment's radiation scares one bit since I have a reasonable knowledge about radiation. But this is absolutely true. It is directional and has a smaller footprint and that will make triangulation much eaiser and more accurate. I wouldn't be surprised if 5G also adds more identifiable data to the exchange. New standard = more chances for new government back doors.
