“If satellites exist, then why would mobile phone operators bother to install transceivers everywhere?” flat-Earthers asked this a lot.
The logic is that if using a satellite can get you a vast coverage area, then spending a lot of money and effort to install towers everywhere does not make any sense. Usually, they would follow-up and conclude that “satellites don’t exist.”
They are wrong. Satellites do exist, and there are good reasons why mobile phone communication utilizes cellular architecture.
