SpaceX states that at the current service altitude, the satellites will
be-orbit in ~~ 5 years. That's one of the reasons they went with the
lower service altitude. The original was up substantially; perhaps where
the 10 year number came from.

with a ~500km altitude, they deorbit naturally after ~10years from drag.

Theoretically a Ubiquiti Nanostation was carrier grade and would do
150Mbps. It said so on the datasheet.
Just saying maybe the small, cheap satellite will work exactly as
intended and maybe it'll have a firmware crash during a sunspot and
just become a piece of high velocity garbage. Even a low failure
rate over many years could eventually leave a whole crapload of them
buzzing around up there.
.....I'm sure people smarter than me have thought of all that.
Haven't they?

WRT orbiting debris; it's all good until the first "accident".
Then we will see how this all shakes out. If it's bad enough, it
could cause SpaceX (and all its brethren) to relinquish all the
orbital space unless/until they provide a mitigation plan. To some
extent they are structuring their constellation to de-orbit
quickly already. Plus their sats are theoretically designed to
de-orbit on their own at end of life.

That explains what this whole CHAZ thing is, they wanted first

Im not a fan of star link, i think its going to cause some major
debris field issues in space for future generations. But nobody
can argue with the fact that it is really cool that a guy like
musk exists who just wants to do some really cool shit, so he
does some really cool shit. Every kid at some point in life said,
I wanna go to mars. Hes just like, yeah, imma go to mars.

In case anyone was watching SpaceX put up another 58
Starlink sats on Saturday. That puts them at almost double
the number they claimed to need to enable their "private
beta". I'm sure it's underway, plus they're running some
kind of test with the US military.
All the sats except for the first batch of 60 are of the 1.0
design. Depending on which news blurb you read, these sats
all have to relay directly through ground stations, or they
have some limited ability to go sat-to-sat via an RF link.
We may find out before the end of the year.
They also stated that they c/would start the public beta
when they had ~~ 800 sats in orbit. By my seat-of the pants
estimation, that will be another 4-1/2 launches from now;
maybe another 3 months. Call it September, but who knows.
I think the biggest obstacle at this point is their pizza
box/flying saucer on a stick user terminal. I heard one
estimate that the build cost for it are in the neighborhood
of $1200.
I would say by the beginning of 2021, this topic will not
longer be "OT".
