I'm not an expert on the Starlink network, but their coverage isn't uniform. Even across the 48 states. The constellation provides more effective bandwidth in some areas than others. SpaceX has a government subsidy to provide high speed internet right across the street from my parents house. But they have no satellite coverage in that area according to their own map. I don't really understand the business plan of Spa…
> But they have no satellite coverage in that area according to their own map. There is nowhere in the lower 48 where starlink has no satellite coverage, I believe there are still areas where they have not built out ground stations though, and since most of the satellites don't have laser links to talk to other satellites (due to issues with their original lasers not fully burning up on re-entry - now fixed) they nee…
For an ISP that uses satellites, ground stations are equivalent to satellite coverage. It doesn't matter how many satellites they have, if there isn't a ground station to connect to you don't have coverage.
Inter-satellite links also don't do anything useful if you don't have enough ground stations. Even if you had a ground station with infinite bandwidth there is no way a single satellite can have the entire network linked through it. It's a really neat thing to have a single voice channel connect through a constellation from somewhere like the southern Indian ocean, but you can't really run 100+ mbps pipes like that.
This is completely different than something like a military communications satellite where both ends of the connection are communicating through the same satellite. The 48 states could be totally in the dark (no power, no comms) and a military communications satellite still functions fine.
