Re: They will be competing with fixed 5G, not 1.5 Mb rural DSL
The satellites don't stop working just because they aren't over the US (or Canada?). In point of fact, anyplace on the planet between roughly 54S and 54N should have continuous coverage. That's roughly all the seriously inhabited parts of the planet except Alaska, Northern Europe and much of Russia. There may be ground station and frequency band allocation complications, but at least in concept, Elon should be able to sell his service to most of humanity. And that's hopefully without impacting service in the US.
