Starlink currently has 69,000 User, according to what Elon Musk said
today at the Mobile World Congress in Barcelona.
In a year, he wants to have 500,000 users.
He expects having to invest 25 to 30 billion US-Dollars to fully build
Starlink.
Each Dishy costs Starlink about double the current purchase price.
However, they want to reduce the production cost to "a few hundred
dollars" - which is why they are working on their own factory in Texas.
FYI

I think that was 69k simultanious users
dishy production cost is currently down to ~$1k/unit (I've heard that it was
~$3k/unit for the first ones)
But the long term upside if they can pull it off is a license to print money,
I've seen speculation that it's on the order of 30B/year when fully built

Keep hoping they will add good, nay, great!! queue management.
Software costs nothing in qty.

I think that's kind of doable.
It's too bad all those users are behind a CGN and cannot talk to each
other, routing calls at least from one village to another would stay
on the same sat.

since they are processing packets they must have some routing or packet switching capability per sat, esp given the ultimate laser based interconnect.
I am wondering how much routing table space they might have designed in?
going village to village on the same sat would save a ton of backhaul bandwidth and offer less latency for things like phone calls. The CGN (dang it) looks doomed to backhaul somewhere, but perhaps the ipv6 stuff?
I imagine they do it at the l2 protocol and program the next hop(s) on the ground, but we do live in an age where everything is centralized
(for those that don’t know, I’ve been working on distance-vector routing protocols for decades, most of my work on that front for the last decade has been focused on making the babel routing protocol scale better than bgp does for meshy links )

500k customers is ~$600m in gross revenue per year. Assuming no operating costs, takes, etc., $10bn takes ~16 years to pay back. They need to add way more customers onto that investment.
In traditional land-based telcos, it is frequent to split the backbone and customer sides, having a “TowerCo” with all the expensive infrastructure, that has a payback period of 25 years, and “CustomerCo” where payback needs to be 12-18 months. In Starlink’s case, unless they cannot increase satellite lifespan, and/or make them very cheap, the payback period is fixed at 5 years. For gateways and ground infrastructure, you can stretch it to compensate, but you cannot justify, say, a 50 year payback.
IMHO the direct to customer side will end up being residual, high price for those who really need it, and their revenue will come from backhauling mobile and FTTH operators, airlines, cruises, and the military.

Mike

they have FCC approval for 1m customer terminals in the US, and have asked to
increase that due to demonstrated demand (to something like 5m terminals)
500k customers is not nearly the break-even point, but that's still a lot of
equipment deployed and supported.
I suspect that they will be more limited by the number of stations they can
build than the interest from customers. As user density increases, they will
need to launch more satellites, but as Starship comes online, the cost to do so
will drop significantly.
the orbital life of a satellite may end up being a bit better than you think,
they will de-orbit by themselves after about 5 years, but they do have thrusters
that they can use to raise their orbits to extend their lives if they don't need
the fuel for collision avoidance.

I wasn’t suggesting 500k users was anywhere near break even point, but the opposite - that they need orders of magnitude to reach profitability.
Lifespan of a satellite is determined by many factors, including decay of solar panels and batteries, or radiation and thermal damage. You can design satellites to last decades, as the GSO operators do, but they become really expensive as a result. The equation becomes “how much time does a satellite spend serving paying customers before it dies”.
The financial modeling is extremely complex. As an example, do you consider a satellite serving a customer for a few minutes a day, at $100/month, as fully participant in that revenue? Or do you assign the proportional amount of revenue to the time serving (e.g. $2.50). Do you book the time satellites are over non-serviced area as a loss? Or just lost revenue opportunity? Does a gateway site become a standalone entity? Or do you have 9 antennas, and thus 9 entities, each with an independent contribution to revenue?
Using all the above as examples, not to start a discussion which would be very off-topic :-)
Best,
Mike

While I agree that big money is in backhaul...
My take on how to turn a per-user profit was easy. Just increase the user density and user side always offer the lowest latency possible from LEO.
I would hate to be quoted on this out of context, but 50Mbit ought to be enough for everyone. Web traffic in particular is almost entirely bound by RTT [1]. There’s a lot of studies showing this. I keep looking for the key google one with no luck….
You can’t use up 50Mbit in your typical 3sec web page load before it ends.
Designing a network for speedtest is silly. (admittedly convincing the world that speedtest is the worlds most misleading benchmark is hard)
Designing a new network for real applications like voip, videoconferencing, email, chat, and 4k video streaming is much easier if you always retain consistently low latency.
Many the headaches and hassle in scheduling a bunch of spot beams go away if you just target real applications, with good queue management, and a deep knowledge of how our network protocols actually work.
There’s plenty that could be done at the l2 layer to increase density also. "Music is the space between the notes” - said Debussy
[1] With *really good queue management* at the head end, and an e2e approach to improving the browsers, we (teklibre) long ago proved how to improve PLT enormously at large RTTs.

My opinion here is that it's a bw game. with 1M customers doing a few
megabits/s each, that's significant amount of bw capacity needed. Even
with tens of thousands of satellites (each significant cost to build and
launch), I still don't really see how they'll handle many millions of
customers.
Terrestrial mobile networks still haven't really come around to unlimited
data that actually works, so we'll see how well Starlink can do this.
There was a power outage affecting around 50k households yesterday, I
presume most peoples' residential connections/wifis stopped working, and
they all went mobile. This rendered the local mobile networks basically
unusable, people reported 10s RTT on some of the packets that were
actually delivered.
5G base stations today are in the gigabits/s magnitude of total air
capacity, even if they have similar for the satellites it's going to be
problematic to keep up. I think they'll have to keep charging a premium
price, higher than today, or implement data cap.

Speaking from experience this is competitive with terrestrial fiber in ROI timescale for rural areas.
It doesn't solve the hyper rural where this is a lifesaver.

Link?
At 250+ms most our protocols start sending more packets, compounding this problem.
Admittedly an outage of this size is probably not something that can be handled with pure fq+aqm, as it would basically look more like a syn flood attack!

I don’t think data caps are needed. fairness is needed.
I would prefer a solution that just billed for usage over a minimum.

Well, data caps is similar to this. People generally don't like to get
billed automatically upon higher usage, thus data caps can be used and
people will have to go to some self-service page and "pay more" if they're
over the cap, to get a higher cap.

[RR] Engineers always think fairness is "needed". Corporate managers who
make the real decisions couldn't care less about "fairness". It's all about
income - expenditures which is simply PROFIT! When fair becomes profitable,
you'll see it. Until then,dream on.
LTE has pretty good airtime fairness (but FIFO per customer). Still
doesn't work very well when there isn't enough airtime to satisfy demand.
[RR] There will NEVER be enough supply (of information carrying capacity in
the network) to meet demand all the time. The reason is simple, until the
supply is exhausted, there's gold in them thar hills and the carriers are
not going to leave it there. They will fill their pipes until they burst,
knowing that there is little if anything their customers will do about it
until their pain threshold is exceed, and they spend a helluva lot of money
on psychologists to let them know where that breaking point is and they aim
to get there ASAP. Why?? PROFIT and MARKET CAP! Business 101!

Well, data caps is similar to this. People generally don't like to get
billed automatically upon higher usage, thus data caps can be used and
people will have to go to some self-service page and "pay more" if they're
over the cap, to get a higher cap.
[RR] The people in charge at the carriers hate caps . they want customers
unknowingly pouring cash into their coffers. CAPs came about when consumers
complained to the regulators, not one day before! CAPs are nothing more than
a compromise that forces the carriers to let their customers know when they
are about to get sc___d.
All communication networks ultimately reach an "uncomfortable equilibrium"
where all parties are unhappy, but not unhappy enough to quit the game.
Thinking that there is some technical means by which 1Gbps can be shoved
through a pipe whose maximum possible throughput is only a fraction of that
data rate is misguided thinking. More importantly, fairness is in the "eye
of the beholder". One man's fairness is another man's inequity. The point is
that any algorithm for handling packets in a congested/overloaded network at
best will satisfy those that run the networks and not disappoint their
customers "too much". It's bloody obvious that finding the algorithm or
algorithms that achieve these two goals is the only path to success.

OK. But does it help Starlink if 3 satellites in a train of 10 run an
extra year, and 3 more an extra half year? Can they reasonably "refill"
the train satellite by satellite?

It’s reasonable to think that it’s segment routed in some way, the
advantages there are numerous and pretty clear. It would give them the
significant advantage of being able to leverage a PCE controller
architecture and provide a lot of LFA options for resiliency. My money
would be there, either SR-MPLS or SRv6.
Not a lot of options for SRv6 at this time (some ur not many). It’s not
outside the realm of possibilities by any stretch of the imagination.

so far they have launched between 3 and 60 satellites per launch, not always 60.
And if they start using starship to launch (which they plan to as quickly as
they can), a single launch can be up to 400 satellites

Yes, that's exactly it. The lower their launch costs, the more it may
make sense to deorbit and replace entire trains rather than individual
satellites within trains.
If that is the case, it doesn't help much that the average life span is
a bit more than 5 years. When a train of satellite starts to degrade,
they may just deorbit the entire train, even if some of the satellites
in the train could still operate for a while.
Or am I getting that wrong?

My point is that a train is already a variable number, so it's not line 1 train
== 1 orbit of satellites
They have had a number of failures and a few deliberate deorbits for testing.
the sateelites they have already launched are sufficient to provide global
coverage (except at the poles), but they plan to launch a LOT more, including
more into the current shell.
So I think it's going to be more a matter of graceful degredation and then
launching a new set to fill gaps than killing an entire train at a time.
If they are going to launch 400 or so on a single starship launch, there has to
be enough delta-v for them to not only space themselves out along one orbit, but
to shift the orbit east/west as well, which gives them a lot more flexibility
than you are assuming.
