High speed bandwidth connecting remote areas will have a big impact. Government wants it for ships, forest lookout towers, epa to watch waters and animals.
Also remote cell sites can be provided with uplinks via starlink. My parents small town has 1 tower that provides everything from limited internet, cable and cell service via microwave. The community center only has internet because of it.
Dialup is almost dead everywhere, and basically useless on modern websites.
Millions of americans only have cell service as their only internet, expensive and bandwidth capped. I replaced my folks hotspot with starlink, its been great for them and when I work from their home. Teams works fine over it.
I'd also expect comcast coverage zones that exclude a few houses will be using it. And areas lacking DSL service.
What I'm looking forward to is when sats have sat to sat communications to route traffic around the world.
Not only those good times, but these V2 satellites will enable direct-to-satellite LTE connectivity on T-mobile, using existing cell phones. Cell coverage anywhere you can see the sky!
A huge benefit to safety in rural and other areas without existing cell coverage.
My brother was just notified that his monthly subscription cost was going down - he was shocked.
He actually uses Starlink in a major city that only has Comcast cable Internet. The service was so slow and unreliable that he was unable to work from home. He happily switched to Starlink and flipped Comcast the bird.
Nah submarine cables have tons and tons of capacity. Fibre is super efficient and you can even use multiple colors to add capacity (DWDM). Radio spectrum is much more limited. Also they don't just lay one fibre at a time. Each fibre has its own clean broad spectrum where radio is always shared.
Sats will not replace them for backhaul. The capacity isn't there. For limited emergencies sure but not for all our Netflix.
This is all great for users in poorly connected areas and that's what it's really for.
Ps: also the sat link is more for remote areas, the network is much more efficient when an uplink is available in the same area and this is also how it provides near cable-like latency. Basically a bent-pipe system. If you'd use this capability for long-distance back haul you'd need to tie up a lot of sats' capacity increasing latency and decreasing capacity overall.
Are users in poorly connected areas enough to be profitable? These satellites have a short lifespan so it'll have to be hella profitable to make up for the constant replenishment launches no?
Satellite service is more likely to replace cell. If the latency gets low enough, and capacity gets high enough, we can expect the Starlink/T-Mobile partnership to expand beyond emergency services. I'd certainly trade speed and latency for total planetary coverage.
No it's not.. It's far most cost effective to deploy cellular. Fiber in the ground to a tower will easily last 50 years. The radio hardware will need ongoing maintenance, but it's still far cheaper than launching 30k satellites into space with a lifespan of five years.
Well for reference: "The current lit capacity of the Southern Cross Cable network is upwards of 5.4 Tb/s, while the Hawaiki cable between NZ and Hawaii is 10 Tb/s. Together with upgrades planned soon, this comes awfully close to Starlink’s worldwide system capacity, quoted to be 23.7 Tb/s worldwide or somewhere between 15 and 20 Gb/s per satellite. Except that Australia and New Zealand between them have a population of just over 30 million — and a lot of CDNs with a local presence. But there are billions of unconnected and under-connected users out there waiting for service." https://blog.apnic.net/2021/06/11/leo-satellites-part-4-why-...
Yeah, the new satellites being announced here have about 100Gbps apiece. They want a constellation of 30,000, have been approved for around 7000 so far IIRC, so they’d have 700Tbps total (less than that usefully as most will be over water). But they plan on another big upgrade by about a factor of 3 with Starship, which should bring aggregate capacity to 2Pbps. This will be most useful for places like Hawaii as the satellites will otherwise be idle, so will have lots of space capacity.
There are also competitors like OneWeb (smaller, but still useful) and Kuiper (not yet running, but potentially a comparably sized project, a project of Amazon’s), so this is just getting started.
This is a really poor way to compare. even with cross-links about 30% of their bandwidth is useable in the best case. starlink has no way of increasing capacity to their heaviest demand areas besides launching thousands more satellites. fiber is much, much, much more efficient.
I consider about 20% of the aggregate bandwidth to be usable (the land area vs total area of the Earth), but in special cases like Hawaii, there’s potential a huge amount of bandwidth since Hawaiians can have access to some of this 80% otherwise-unused portion.
Sure, but the problem is that the places you might have high bandwidth might already have good access to internet. Hawaii in general has very good internet already, so asking them to pay a premium for satellite internet isn't always a good trade.
Total international Internet capacity is 997 Tbps, according to Google. If they need more, though, they’ll presumably add more wavelengths to existing fiber. That puts Starlink at about 2%.
No, but it makes business sense to require users to buy a new dish anyway.
New dishes can make better use of limited frequency resources (eg. They support polarization). So they can squeeze more users in the same bandwidth if everyone has a new dish. So at some point, they'll require everyone purchase a new dish.
And fewer hardware versions to support is less burden on the engineering team.
That is part of why I think they should be providing the dish hardware for free as part of the service... The incentives are misaligned if the user buys the dish but spacex decides when it's deprecated.
