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.
- unnouinceput 7y agoYou underestimate the hunger. It's a new toy to play with for billions of people. Pretty much 3k satellites at 1TB/s each is equivalent of a bucket of water for a stadium full of people. And they plan to give this access for free. It will overload their network and realize they will need 3 million satellites instead, at least.
- portyllo 7y agoSpaceX satellites cannot handle 1 Tbps each, they can handle 23 Gbps each according to their FCC filling.
- shaklee3 7y agoSpaceX satellites cannot do 1Tbps, and it's irresponsible to keep saying this. See the MIT study. They estimate ~20Tbps of total capacity for 4000 satellites.
- ehsankia 7y agoCan you attach said MIT study?

- shaklee3 7y agoAwesome work. Are you going to update it for the 10,000 satellites + Amazon? I'm guessing the answer is no. Also, are you looking for a job after graduation? If so, please email me :)
