My understanding is that in addition to distance latency there is some non-trival amount of latency due to the use of TDMA. Unlike CDMA where everybody piles on the same spectrum at the same time, TDMA gives a timeslot to every station and you gotta wait your turn before TX/RX (this is a gross oversimplification of course).
While it doesn't add that much latency it is more than CDMA.
- syncsynchalt 5y agoNot just TDMA - lasers in vacuum travel at the speed of light, but signals in optical fiber and coax copper are both 2/3 of that. This means that if (and that's still an if, not yet a when) starlink does laser between satellites it can beat terrestrial speeds. I could see the end result being that we still do bent-pipe signaling over land and only laser interlinks for crossing oceans and for customers that pay for low ping to financial markets.
