So what it's gonna be like - latency and bandwidth?

For latency at LEO, we're looking at below 50ms, going as low as 20ms. For bandwidth, it obviously depends on load and usage. SpaceX's satellites each can handle 1 Tbps, so it comes down to how they distribute and price it. At 100Mbps and 3000 satellites, that's roughly 10 million users. Obviously not all users will be using that much data simultaneously.

SpaceX satellites cannot handle 1 Tbps each, they can handle 23 Gbps each according to their FCC filling.

I wonder if it would ever make sense to set up some "IXP satellites" so that Amazon and SpaceX's (and whoever else enters this space) various LEO networks could switch in space.

Developing compatible systems would be very expensive. There are very few standards in Space Comms., specially for satellite-to-satellite Comms.

Satellites also have to be specialty built for their purpose. You can't just take a small communications satellite, attach a small camera, and have a spy satellite. Well you "could" but it would be so crappy that it'd be useless. Also LEO satellites lose their altitude rather quickly, not a great investment for spy satellites. > Satellites are outside the regulatory authority of countries they operate over. Except th…

These would make poor imaging satellites you are correct, but what could possibly be more valuable intelligence than a global scale firehose of data. Just the metadata of packet routing across the constellation would have huge value to intel agencies. To say nothing of the implicit value in denying an adversary access to that information.

There's far more efficient ways of tapping global data than launching satellites.

Just build undersea fibre if surveillance is your goal.

IMHO, it would be nice if the decay orbit for each satellite were tracked accurately by Amazon and published beforehand. If these satellites truly do burn up completely -- great. But if they don't it would be great to hold Amazon accountable for any problems and for waste cleanup.

> accountable for any problems and for waste cleanup These are companies, not people... $10 buck says if one of these things hits your roof, Amazon will just give you a $100 gift card to Amazon.com

+1 lol. yeah. I guess that's better than nothing.

I am looking forward to when Huawei put up their global network... Charge zero for the uplink devices if you buy the first 6 months up front using bitcoin. With free Huaflix and sports channels (unlicenced, use at consumers own risk).

And be perma-banned for accessing harmful content.

No, it's just negative social score, so you'll lose your rented place and can't take public transport anymore.

This is not true as far as I can tell. HFT does not appear to be part of spacex’s strategy at all.

Specially now that the satellites have no crosslinks.

My understanding was that was just a limitation on the first batch, as they're still developing the design, but they're intending to cross link in future. Is that not the case?

"If Amazon stops serving its customers well it'll go out of business. If it pisses people off it'll go out of business." This is the central myth of the free market. Part and parcel of a massive internet company is having control over the flow of information, how can people protect their rights if they don't even know they're being violated, or if they're being distracted from protecting themselves by lies and manipu…

> This is the central myth of the free market. Tell Sears and Kmart that it's a myth. Top US retailers in 1970: Sears, Pennys, Kmart, Woolworth, McCrory's, WT Grant, Genesco, Allied, May, Dayton-Hudson (Target) Only one of those remains on the list now (in an entirely different form at that). The Internet has changed nothing fundamental about whether a retailer can be replaced by competition. And no, Amazon's warehou…
