Genuine question - why is it a given that there will be latency issues? It looks like the satellites are only ~350 miles, or a little less than 2 light-millisec

Genuine question - why is it a given that there will be latency issues? It looks like the satellites are only ~350 miles, or a little less than 2 light-milliseconds, from Earth's surface.
- Torkel 6y agoPreconceptions. Satellite internet have traditionally been slow+laggy. Starlink is not. Yay first principles :)
- kumarvvr 6y agoThe issue is with overall latency. User -> Satellite -> multiple hops between satellites (as they are orbiting earth and the right one has to be selected to relay data to -> earth DNS servers -> multiple hops across internet -> satellite -> user Additional latency is introduced due to satellites and the grid between the satellites, as well as complications from rotation of satellites.

- sneak 6y agoStarlink does not at this time use any intersatellite communication links, despite having talked about it.
