There is also Starlink direct-to-cell where regular phone can use LTE with satellites from anywhere. It looks like there are two other companies working on same technology.

I wonder if there is a market for worldwide coverage with fast data without the capacity for broadband users. That would lower the number and capacity of satellites.

Alternatively, it might be possible to do broadband with larger but fewer satellites instead of Starlink strategy of increasing capacity with more satellites. Other companies could save money by not having laser links and only do bent pipe.
