Well I guess it's only 6db more to get to 200 miles.
I followed links to the application and they're talking about Ku and Ka
bands.
That's as far as I'm going to read during the work day. I'm still
curious how much tx you would need your CPE to get a useable uplink path
to the satellite, and how big of an antenna.

At 100 miles, I would think that the decay rate would be too high.
Usable, low-maintenance LEO would probably start around 200 miles, but
IANARS (I am not a rocket scientist).

....yeah but GPS doesn't need an uplink.
So if you have an antenna of similar size and shape to one of those
cone shaped GPS antennas, how much tx power do you need to hit sats in
LEO? That's at least a hundred miles up isn't it?

They won't need to be south-facing. With 4,000 of them, they'll be
everywhere going everywhere. I'd think like GPS.

Article says client side antennas will be phased array to track the
sats, also that the sats will communicate with each other.
Seems to me even with all those sats, talking about gigabit service
to customers is a bit of marketing hype.
Speaking of marketing, that would seem to be the key, how will they
market this? Unless the target market is the same people who bought
Iridium phones.
SpaceX does not have a natural existing marketing vehicle for
Internet service, I assume they will need partners or resellers.
That is the advantage a Verizon, AT&T or DISH has – millions of
existing customers they can advertise to, and offer bundle deals to.
Satellite does have a natural appeal to the “nothing on my house”
people, you can stick the antenna on a short pole in the yard. Still
not a great solution for the apartment and condo dwellers without
south facing balconies, they want indoor wireless modems. I am
assuming the LEO orbits will still be in the southern sky like GPS
sats, maybe that is wrong and they will whiz overhead in all
directions?

I didn’t see what frequencies they are using.
Earth stations would need to track them I would think.
