Commsats in GEO have a minimum half-second round-trip delay time. Hence the
use of LEO satellite constellations
About 9ms round trip from a LEO satellite.
Downlink speeds are 32x that of uplink speeds (at least for Teledesic
satellites).
Some of the smaller networks (OrbComm) which are simply messaging systems
have bandwidths as low as 2400baud up and 4800baud down. Which is plenty for
even a 2060 pager.
Estimates for most constellations advertise they will cover nearly 100% of
the earths population and 95% of the landmass. Give or take a few percent.
