Not too many options. It has to be either that or some moving parts.

Sure. But after the clouds, geostationary still needs to go
another 23,000 miles. LEO only has to go a few hundred.

Same amount of clouds tho.
What’s the free space path loss of outer space??

I think one factor advocacy groups and govt critters need to keep in mind is
that instead of robust competition, what could occur is “disruptive” pricing,
having the effect of discouraging or bankrupting the competition. And now some
new entrant is the only game in town. And if it turns out

I am curious how their CPE will track the satellite. If it does not track
it I doubt it will have enough gain to have decent throughput. I presume
some kind of pizza box with phased array of patches doing beam steering.

What kind of bandwidth capacity could each satellite have at any given point?
What is the usable bandwidth of their system? Who makes a radio that big to
carry/transmit such capacity or is it an
aggregate of small radio's?

Yeah, I know. And considering that it generally takes a pretty big storm to
take out a geostationary satellite signal, I imagine it won't be too big of
a problem... but I wouldn't be surprised if it did turn out to be a big
problem either.
