  5.  @dorfsteen  Whether satellites are real or not, or whether calls are routed overseas via undersea cables, is irrelevant to how cell phones work. Cell phones are not claimed to work by connecting to satellites by anyone with basic knowledge of cell phone technology. It is no surprise you lose service in some areas. The maps you mentioned show the "dead spots". It's no secret there are dead spots. Those are areas where there aren't any cell phone towers nearby to provide the service. BTW iirc the reason we still use undersea cables is because they transmit light. They are optical cables. Light can carry more data at a higher speed than radio waves because the light is at a higher frequency than radio waves. They didn't have laser based communications when they laid those cables. Or maybe it was cheaper to lay undersea cables than to launch satellites into orbit. They certainly do have some sort of radio transmitters in the sky whether they be high altitude balloons or satellites in geostationary orbit. Otherwise your satellite tv dish wouldn't need to be pointed towards it. So if they can fake a satellite using balloons why would they lay cables under the sea? It would be easier to launch a high altitude balloon with a radio transmitter attached. You see the problem with your logic? I'll admit it is strange they haven't simply used lasers to communicate instead of laying fiber optic cables undersea. But like I said maybe it is cheaper to lay cables undersea. Satellites which transmit signals using lasers may require high power lasers too to get through all the particulates in the atmosphere. I know such satellites are now claimed to exist. They are being used to build a quantum internet where entangled photons are used for quantum encryption. This tech has probably been around longer than the public has known. But it is only within the past couple decades that I have heard of laser based communications. So it's relatively new in the public arena.
