i.e starlink can get much lower latency between say London and NY than terrestrial links.
That's the thing, the speed of light in fiber is actually significantly slower than the speed of light through air, which itself is slightly slower than the speed of light through a vacuum.
Over long enough distances this adds up to the point that high frequency traders already have built radio relay networks between New York and Chicago. You can't easily build radio towers across oceans, but a satellite relay network that could follow a nearly line-of-sight path is almost the same thing.
Also fiber isn't run as the crow flies, sometimes it has to take a winding path which adds even more distance to the run than you might think, on top of the reduced speed of light.
If Starlink manages to get their satellite to satellite laser link tech working, which is a MASSIVE if, they're in a very good place.
( It doesn’t matter as the boost from not using glass as medium for light makes it no contest anyway)
It's been a while since I watched them, but I recall that even without laser links, they can beat any of the terrestrial links over a certain distance - because the terrestrial links can't get direct-LOS.

It will not be faster than fibre for Manhattan to Princeton , but it would be faster for London - New York or London-Frankfurt
What SpaceX shared is that they plan to be "fiber cable" except via space. They'll carry a backbone traffic e.g. between Australia and U.S. via laser links.
Companies that currently pay for undersea fiber cable to carry traffic will pay Starlink for the same service.
Also, a backhaul for 5G operators (see https://www.telecompetitor.com/starlink-update-musk-sees-mob..., https://www.zdnet.com/article/japanese-telco-kddi-to-use-spa...).
Also airlines.
I used to work for a company doing microwave backhaul and they liked us as the speed of light through air is faster than fiber, and they could get more direct links. It was important enough that we had special low latency builds of our firmware with some features removed.
Big ass yagi uda antennas in certain locations with totally custom rf chains and modems.
Do you have any sources/further reading? I'd be curious what type of licensing that operates under etc.
Edit: Turns out there's an article on it on the very same blog [2]!

All FCC fines are public info (called a notice of apparent liability and published in their daily data dumps), I've yet to hear of one getting fined.
Offshore oil and gas, cargo ships, Cruise ships, coastal vessels, medium-distance ferries such as in Greece, business jets, airliners, portable military applications, data links to offshore scientific applications for buoys and weather, all sorts of stuff.
Verizon and AT&T built multi billion of dollars a year of sales from cookie cutter DSL (simplistically). All these crazy edge cases…are they material? Does it make sense to shoot thousands of satellites in space for ferry boats in Greece? Financially that is.
That being said it’s really cool what a “catch all” solution we’re getting as a humanity for basically free. This feels like Google Maps / Gmail / WhatsApp where all humans get like value for free (especially in the developing world) due to one company creating a massive positive externality due to their business strategy. So cool.
> The consequences for SpaceX if we can’t get enough reliable Raptors made is that we then can’t fly Starship, which means we then can’t fly Starlink Satellite V2 (Falcon has neither the volume nor the mass to orbit needed for satellite V2). Satellite V1 by itself is financially weak, whereas V2 is strong.
I very much hope they both do work but let's be clear there's still a lot of risk to get through before that's clear.

Additionally the US and NATO would see an act like that as barely one step below declaring nuclear war.
If anyone in NATO considers blowing up satellites to be one step below killing hundreds of millions of people, I want that person fired. Because they have completely lost touch with reality, and should not be allowed anywhere near a weapon, or a job where they manage people with weapons.
The reason taking out spy satellites is taken so seriously is it is considered a likely prelude to an attack.
I'm sure people are wargaming this.
Is it, though?
Can you share the pricing details of managing 4G towers vs. Starlink's small sats.
And yes, I fully expect that you have no idea what either of those costs.
4G serves an entire nation of cell phones, using generally similar wireless technology and limitations LEO satellite comms have. 4G towers are closer to the users than LEO satellites, meaning the power requirements are lower, this is a desirable thing for the people in terms of both battery life and radiation power levels.
5G takes it even further in this direction using more towers; shorter distances and lower power levels, AIUI.
Unless I'm utterly mistaken, LEO satellites are at a severe disadvantage when it comes to competing with the cell network for handheld mobile customers.
Satellite connectivity has its place, and it's basically where you won't have cell service, since that's obviously the preferable option if it's available.
I have a pretty rural property and there are areas nearby that get 5G UW with speeds in excess of 1Gbps. Most of the area is covered by 4G with download speeds of over 40Mbps.
5G is already replacing wired home internet for many people. Give it a few more years to expand coverage and I bet 5G will make Starlink obsolete for most of its US users.
This is wrong. Years before they have a full constellation they will already have started needing to replace previously launched satellites. It's not like they just launch them once and they're done and those satellites last forever. Just to maintain a constellation they'll need to be replacing something like 20% every year.
Anyway, for spacex to make bank off of this they need customers. Extreme rural living areas are not that common, and when they do become common more cost effective methods such as cell towers make more sense than starlink.
I worked for a Telco installing 4G (and 3G) towers in some of the most remote locations on Earth (the Arctic).
I can assure you, they ARE that expensive to manage.
Some of my code is in the arctic vault though a piece of crap Todo List.
What's special about satellites (and how much caching are they gonna do) and why are you worried about data you have chosen to send in the clear over a network you don't own?
Don't worry I'm not an Elon hater
The satellite is like a piece of debris/wreckage which someone pointed out it would have deorbited anyway at some point.
The videos "has an agenda" but it seems a bit easy to accept the idea that constantly launching satelites into space is pretty expensive. Infrastructure on the ground is expensive, but most people tend to not move around so at one point just building out lots of wires everywhere can work pretty well.
Having great coverage across the globe is great! But especially after seeing that (super crappy!) satelite internet providers getting the same shit done with 3 satelites.... you're looking at the intersection of people needing access to fast internet who can't somehow take advantage of existing infra, _and_ who won't eventually get covered by ground infra (and I guess don't have trees around their house).
You don't need to worry. Every angle for making the comparison unflattering to SpaceX, including taking screen grabs of Elon Musk with funny faces and making character attacks on him on the basis of his face looking funny, are more then covered in that cesspit designed to radicalize and monetize the gullible.
To get a sense of the scale for overcounting elsewhere in this thread someone pointed out we could do the calculation ourselves. They determined a reasonable number of satellites. Their estimate of the needed number of satellites was 37,000 less than CSS's estimate.
Whatever lie, whatever unflattering take, whatever deception - this video tries every angle. If you want to be delusional, this is your video author. He will help you get there.
The video lies about the connection speed. The video lies about the latency advantages. The video lies about the costs (by several orders of magnitude). The video lies about a government conspiracy (claiming one exists). The video lies about the ability of women to make effective decisions (implying they can't).
Ground infra can suck. It will probably be stuck at 6Mbps down forever since it is not economical to upgrade it. I would literally cut down trees by hand if it meant I could have fast internet.
Having competition changes the economics, at least somewhat. Look how fast AT&T rolled out fibers to all the cities Google announced they were going to do fiber in. It's still expensive to do new runs everywhere, but it may be worthwhile to keep some business. In some areas, as some customers leave, staying customers may be able to have better access to bonded lines. In other areas, the carrier just needs a kick in the pants to use more flexible/generous profiles to let customers use the speed that's available.
The idea is to use starship which should be really cheap.
Reused Falcon 9 launch: $15M[1] in the best case, but let's double it just to ballpark the average, so $30M. Falcon 9 can loft around 50 satellites per launch. 30M/50 = $600k/satellite.
Starship: Aspirational goal of $2M cost to launch. Let's just round that up to $10M for whatever might be more expensive than expected. Starship has been predicted to be able to launch around 400 Starlink satellites at a time, the last figure I saw was that Starship launches would carry "100 plus" Starlinks[2]. $10M/100 = $100k/satellite. This is assuming Starship is launching v2.0 satellites though, rather than the current v1.5, which are way heavier (1 metric ton vs ~290kg)[3].

I guess the overall thing would be to break things down and figure it out. I'm skeptical mainly from a "possible market share" perspective ($99/month works well for some, way less for others, and honestly the competition is not wired broadband but cell networks). But I am here to be proven wrong!
Basically, cost calculations assuming traditional launch economics are incorrect. That's pretty much the whole point of SpaceX as a company - their business proposition is massive reduction in kg-to-space costs.
Surprisingly not that bad. The real cost could be double and they would still have enough capacity to serve high speed internet and break even.

To just restate that to try to get across how extremely different your estimate is from his. If you convert to percentage and round at two decimal places... your estimate is 0.06% of his estimate. To try and make this different a little more real for people lets try to convert it into more familiar figures. If were talking about a house rather than rocket launches and cp thought the price was $100,000 for a house then CSS would have an estimate more than three orders of magnitude different. Something more like $100,000,000. Translating this level of difference in evaluation means the disagreement in 'real object' terms is roughly equivalent to this much difference in cost estimation: $120,000,000 home https://www.zillow.com/homedetails/329-Albion-Ave-Woodside-C...? versus $125,000 home https://www.zillow.com/homedetails/31235-Manton-Rd-Manton-CA...
The difference in estimates is absurd. The reason it is that absurd is that CSS tries to argue that SpaceX couldn't work because it would cost more than the entire economy in the world. It's like a comedy thing where he tries to use rhetoric about how stupid SpaceX must be to strengthen his argument that they could succeed without an overarching conspiracy helping them lie about everything. This is absolutely a conspiracy video, not a factual video.
IIRC, he moves on from this topic shortly after that to talk about how since Shotwell is a woman she isn't worth respect. It hits harder, if you believe him, because he just made a 'strong as long as you are delusional' case that anyone who thinks SpaceX might ever be profitable is insane.
If I were to state my actual opinion on him on Hacker News, I would be downvoted. If I were to try and express how I feel about someone else finding him at all reasonable, I would be downvoted. So in the kindest possible way let me direct your attention to the kind of techniques he uses.
At 7:16 in that video he posts a screen capture of an article headline. It is a screen capture? Honest right? Great data. Not so fast. The screengrab was photoshopped. He edited out part of the title. In particular, he edited out the price for SpaceX to launch a satellite to orbit. Why, you might wonder, would he do something like that? Well... he was lying about the price just before that, so it would be kind of inconvenient to let people see the truth, wouldn't it? Here is the article whose title he photoshopped: https://www.nextbigfuture.com/2019/12/spacex-starlink-satell...
This isn't an uncommon thing for this liar. He regularly and willfully does things like this all throughout the video. You should be taking every number he gives with an enormous amount of salt. Dump the entire fucking salt container on this meal. He lies about the cost for SpaceX to launch, a material fact, but he also double counts the number of rockets they will need to launch, another material fact. He lies about the speed test results for SpaceX (by using numbers from months before the video, rather than the actual numbers). Since he lied about that, his reported numbers didn't agree with, ya know, reality. In particular they didn't agree with the reality of SpaceX qualifying for various government funding initiatives for rural internet. So if you want to believe him you're going to need choke down a helping of "enormous conspiracy" in order to get onboard his hate train. He also lies about the cost of competitors. And... it's bad. It is so bad that I have 0% confidence that he operates in good faith and I assume anyone who trusts this person is truly lazy, because he isn't trustworthy. Not even close to it, at all, whatsoever.

Viasat offers 30mb/s download for $199/mo with a 150GB data cap. HughesNet offers 25mb/s download for $159/mo with a 75GB data cap. Starlink offers ~100mb/s download for $110/mo with no data cap.
Viasat/HughesNet have geostationary satellites which results in almost unusable ping (300-600ms), compared to the 50ms ping from Starlink.
But, hilariously, despite the channel being called "Common Sense Skeptic" (thought it might be a science-y channel), every video is an Elon Musk takedown.
"Has an agenda" indeed, haha!!
The videos produced as a general rule will cherry pick information and also use outdated pieces of information and then mash them together to produce the illusion of something being much worse than it is.
- Starship will further reduce SpaceX's already low launch costs.
- Economies of scale by producing 10,000+ satellite.
- Industries willing to pay a lot for truly global coverage (maritime, aviation, oil, military)
- With the laser network, high frequency traders willing to pay a massive premium for the lowest latency connections between financial hubs.
- A "fully and rapidly reusable" Starship, if achieved, will change the economics even more. Not only will it further reduce the initial launch cost, but you could imagine potentially servicing/refueling or recovering aging Starlink satellites.
- Starlink (plus increasing work-from-home opportunities) has the potential to (slightly) redistribute where humans are willing to live to more sparsely populated areas.
