> the market is moving to satellite service on regular phones.

I don’t think there a unified “market” here. The fixed rooftop terminals and fixed-ish roaming terminals use high (tens of GHz) frequencies with correspondingly wide bandwidth, have excellent beamforming capabilities and some degree of MIMO to improve spectrum reuse, and consume an amount of power that would be outrageous for a phone. Phones don’t have reliably clear views of the sky and have much weaker RF capabilities.

Oh, and phones are well served by existing 4G and 5G networks in dense areas, with better spectrum reuse than seems practical for a satellite constellation.

I expect that we will actually see two separate markets that happen to share the same satellites and backhaul.
