Aren't there some electrical utility companies that are experimenting with broadband interenet connection over electrical transmission wires? I'd think that would have better uplink speeds. It's too bad Iridium charges so much for their services. Iridium would be an ideal way of getting broadband internet in remote areas.
Yes and the HAM radio operators are fighting it BPL (broadband over power line). It interrupts communications in a number of radio bands.
The problem with broadband over powerlines is that it is likely to trash am radio, not to mention ham radio. Powerlines were not meant to carry broadband and the FCC is ignoring their own rules that have been around since forever to hand the power utilities a moneymaking opportunity
