The latency and bandwidth are fundamental limitations of physics which are incredibly expensive to scale up compare to cable and cell towers.
Latency is theoretically much better because the speed of light is much faster in the vacuum of space than fiber optics. So the ping from continent to continent is better using a satellite network that transmit data to each other using laser light.
I suspect we could be moving the orbit of the satellites higher so we can reduce the insane number of them, while still have better ping. I don’t see a technical reason why bandwidth would be more limited in space than on the ground. It’s fundamentally easier to scale since you can just launch more satellites along certain orbits to add bandwidth.
The fundamental problem is of course privatization and the inevitable monopoly. It will never really be cheaper than land based internet, and so both will continue to coexist, so it just adds additional resource waste for no real benefit except to make some guy rich.
So what are you trying to say? You signal goes up a few kilometers, then you’re in near vacuum in space where signal travels with proper light speed and results in faster transcontinental ping.
There are no clouds and atmosphere in space. That is what makes it space.
EDIT: Actually radio signals already travel near speed of light in the atmosphere. Only light in fiber optics is about 66% of speed of light.
EDIT2: Oh wow, a Chinese research initiative just achieved a breakthrough with hollow core fiber optics which does transmit close to the speed of light. This could render that advantage of sattelite internet moot! Upgrading cables is going to be a massive infrastructure project though.
and what’s in those few kilometers? not atmosphere? Sure the signal travels a bit faster between satellites themselves but this is not relevant in modern networking. Almost everything is cached on edge in your regional server these days so only “the last mile” is what matters for latency. Even if you ignore all this the math would still favor cable every time - 66% reliable speed of light will always beat “potential 100% speed of light sometimes for some part of the distance”
I can imagine some use cases for faster ping between two low orbit satellites could be important but my imagination begins and ends at rocket guidance. I don’t see that ever being useful for 99.9% of networking. The signal has to go down to earth receiver at some point and atmosphere and dish overhead will always lose to a cable.
It’s a boring answer - but cable will remain undefeated until some magic breakthrough in physics comes along. It’s simply just that good.
I can’t remember where I read it, but there was an article in high finance tech, where they were dealing with billions of transactions per second and relied on sub-millisecond timing. They still used terrestrial long-haul (cross-continent) microwave tower networks for this because even the time it took to transceive between optics and electrons in each switching segment meant fiber was slower. The latency tolerance for those applications preclude the drive up and down to space.

Vacuum of space? Dude there’s an entire atmosphere with clouds and shit in it.
In low earth orbit?
yes, where else it would be?
