Eric, you probably know a bit about capacity at low frequencies. Higher frequencies are used for mass communication because there isn't capacity at low frequencies. Frequency reuse in smaller cells is essential to provide capacity. It's also more efficient to send signals around the world by fibre than by omnidirectional bouncing off the ionosphere. With fibre, just a short low energy wireless hop is needed from where you are to a fibre access point. Billions of people and things can communicate via fibre and send petabytes of data per second, hither and yon. I would rather depend on my cellphone system for a tsunami warning, direct from monitoring devices, than have some human detect a wave then crank up the alarm when they get back from lunch. Or fail to wake up at 3am when their alarm goes off. Mqurice
