You tell me when they run a fiber directly into your home. And will you have a mega reel of fiber connected to your cell phone and that cell tower, You don't know what you're talking about.
As a matter of fact, there is fiber on the pole right outside my house, connected to my modem via 75 ohm coax. Delivering 100 MBPS all day, every day.
Cell phones are a different animal, and do use RF.
And yes, I do know what I’m talking about regarding the history of governments attempting to control the free flow of thought and information.
