Re: general communications, and rural broadband,
Except when you spread the capacity over an entire county it's tiny compared to a fibre fed cabinet. But the capacity may indeed be the total capacity for the fleet / world and only a fraction of that even available in one place at one time.
There is a good reason why OneWeb has gone bust.
Satellite Internet is for users off the grid, in the wilderness, out at sea, in an aircraft. Not for British Rural. Not even these days for Africa (Mobile in rural areas, fibre in the cities).
