But at what cost to latency? Sounds like gamers would probably hate it.
Oneweb claims 32ms average. https://arstechnica.com/information-technology/2019/07/onewebs-low-earth-sat... This is one of the main advantages of LEO over geostationary. LEO is around 1,200 miles above the earth, GEO is around 22,000 miles above the earth. That's a big difference in latency. Remember that radio travels at the speed of light. That translates to ~118ms for GEO, and 6.4ms for LEO (one way trip). That means that the round-trip latency without any transponder latency equals 12.8ms for a low earth orbit signal, compared to 236ms for a GEO signal. Big difference. This is a good read perhaps: https://www.iridium.com/blog/2018/09/11/satellites-101-leo-vs-geo/ I no longer work for a satellite ISP, for the record. Thanks, Sabri
