A cell tower today is basically a selective directional broadcast of ~2.5GHz backed by a microwave backhaul, conforming to local topography and about ~3 miles away.
An internet satellite is a phased array broadcast of ~20Ghz with a microwave backhaul without regard for local topography and about ~600 miles away.
... I am not sure there is obviously a better choice here, if the launch costs no longer dominate.
