The plan for nationwide fiber internet might be upended for Starlink
-
If your nationwide fibre internet plan rollout was even half as bungled and bullshit as ours here in Australia, it must be a shitshow. It was used as a political pawn, with one party wanting to NOT finish it so they could use it to help get them re-elected endlessly, and the other party opposing it because it wasn't their idea, and pushing an alternative terrible plan that was far slower and far more expensive in the long term. In the end we got a terrible mix of both.
We've already given telecoms well over $100 billion, over the last 25 years, and they've done fuck all

there's nothing better than optic fiber because nothing can be faster than light
Edit: as comment below says optic fiber isn't actually faster, but still better because it has lower packet loss, is cheaper and not owned by elon musk

Every single time the land line ISPs have gotten money for rural broadband, they use it for something else and don't build anything. Starlink actually built a network that works. Many places have gotten decent 5G home internet too.
I have been promised fiber for over a decade yet the only wired connection available is a DSL network that's been so poorly maintained that it barely even functions.
Do you mean works or falls out of the sky routinely to litter the earth? We build lots as far as smaller ISPs go. You just don’t have any idea what you’re talking about.

Light in glass is actually surprisingly slow
After some distance, starlink would have better latency, as while the signal needs to go through a bunch of km of slow atmosphere, it would make up for that by having a big part of the signal go through vacuum between satellites
But latency isn't everything
Fiber (when properly installed) is very stable. Satellite and mobile is always at least a little bit flaky

St*rlink orbits at 500 km so you would need to be like 1800 km by land away from your destination to have a better latency. At that point your latency will be terrible anyway

Hard to calculate exactly.
Latency is lower through the atmosphere than in glass (I thought that air was worse, but turns out it's not. Makes sense. Glass is solid after all)
So it could be even closer than that. But there's also the problem of the SL base station having to do the last bit of the route through fiber to the destination again. Do it also depends on where the base station is located in regards to the destination

I've heard starlink is faster than fiber by a few nanoseconds and big finance really wants that for their high-speed trading
most of its signals move though space, compared to the glass in fiber so it sorta makes sense

Starlink can be more direct as well. The further fiber goes the less direct it is. By the time we're talking between continents that builds up a lot.

Why would they fall out of orbit?
They deorbit every 5 years and burn up in the atmosphere they don't make it to land (although i think i remember a a part of a very early version did and changes were made because it did, but that might have been something else)
There have been a couple launches where some solar radiation caused damage or a problem with the stage 2 and they all came down and burned up before they made their planned orbit. On occasion, there may be a faulty satellite that doesn't reach its proper orbit after launch and instead comes down instead.
Short of an error during launches, it's all planned.

Its not, light is the fastest AND isnt as interuptuble and lag induced as satalite. A wired connection will ALWAYS have lesslatency to a sat link.

The problem with fiber is it isn't direct, and the satellites do use lasers (light!) to travel longer distances. The longer the distance the bigger edge satellite internet gets.

It depends on the distance, but yes. Those laser interlinks are fast.

I miss dial up. Like local providers with 2 or 3 numbers to try.

light in a vacuum is fastest
light in glass is slower than that
actually think about this before you reply

It was basically up to the states this time around, they could allocate BEAD funds more or less as they wanted and absolutely build fiber out to the vast majority of residences (look at North Dakota, it's evidently possible) through models like municipal fiber.
Ultimately it's a political issue more than anything else, Americans just can't get anything done anymore, politicians would rather enrich themselves and voters only care about the culture war.
I wish there was more municipal fiber. It's absolutely insane that the big ISPs fight it and often win.

That's...not really a cogent argument.
Satellites connect to ground using radio/microwave (or even laser), all of which are electromagnetic radiation and travel at the speed of light (in vacuum).
Light in a fiber travels much more slowly than in vacuum --- light in fiber travels at around 67% the speed of light in vacuum (depends on the fiber). In contrast, signals through cat7 twisted pair (Ethernet) can be north of 75%, and coaxial cable can be north of 80% (even higher for air dielectric). Note that these are all carrying electromagnetic waves, they're just a) not in free space and b) generally not optical frequency, so we don't call them light, but they are still governed by the same equations and limitations.
If you want to get signals from point A to point B fastest (lowest latency), you don't use fiber, you probably use microwaves: https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/
Finally, the reason fiber is so good is complicated, but has to do with the fact that "physics bandwidth" tends to care about fractional bandwidth ("delta frequency divided by frequency"), whereas "information bandwidth" cares about absolute bandwidth ("delta frequency"), all else being equal (looking at you, SNR). Fiber uses optical frequencies, which can be hundreds of THz --- so a tiny fractional bandwidth is a huge absolute bandwidth.

I'm a complete laymen when it comes to this, but this sounds like it would pertain to latency rather than bandwidth. I expect that fiber would have a much higher data capacity than satellite.

Better get to work laying cable.

Yep, you're right --- I was just responding to parent's comment about fiber being best because nothing is faster than light
