I have a serious problem with the allegation that we have the Webb telescope a million miles away broadcasting high definition images.  Everyone knows that the more concentrated the signal, the shorter the range.  Also, to get decent bandwidth, you really have to target the signal.  How do you do that when Webb is speeding through space at high speed, the earth is moving around the sun at 65,000 MPH and rotating at upwards of 1000MPH?  At a million miles away the earth looks pretty small, and a satellite receiver (I don't care if it's the size of a football field) would be so tiny as to be undetectable even if Webb turned its optics towards it.  Finally, the POWER required to transmit a signal that far would not be possible on a satellite.  If they had the technology now to broadcast signals this far, they wouldn't need to put 5G transmitters every couple blocks.  That also speaks to the fact that the more concentrated and "high-bandwidth" a signal has to be, the shorter the range.  With 4G, you could put up towers every mile or so and you'd be fine.  With 5G, you need a transmitter every few blocks to make it work.

Speaking of line-of-sight microwaves, the world record high-bandwidth microwave transmission goes across the Mediterranean Sea, I think nearly 300 miles.  Microwave must be line of sight, but over 300 miles, there would be over a mile or two of globe curvature putting the receiver out of sight.  Specs from the company indicated that the receiver tower is about 150 feet high.
