You're thinking of traditional large satellites in geosynchronous orbit, which is 35 km above the surface (ping time of about 250 ms). SpaceX's plan is to put 4,000 small satellites in low-earth orbit, 625 km up. That gives a ping time of about 4 ms to the satellite.
SpaceX can do this far cheaper than others because they can launch the satellites for "free" as part of launches that are happening anyway.
- vardump 10y ago> which is 35 km above the surface (ping time of about 250 ms) Surely you mean 35000 km?
- larrypress 10y agoActually, they are planning on a low-Earth orbit at around 1100 km, which will require a constellation of satellites to maintain ubiquitous coverage. That will cut latency -- particularly on long routes since it will cut the number hops between hosts, see: http://cis471.blogspot.com/2014/11/elon-musk-and-greg-wylers-plan-for.html http://cis471.blogspot.com/2014/11/elon-musk-and-greg-wylers...
