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.
And prove to me that this “link” is all fiber all the way. You can’t. And you still don’t know what you are talking about.
