5 GHz is more weather affected and more line of sight than 2.4 GHz.  Range
also depends on bandwidth - more bandwidth = less range.  You could get 2.4
GHz to work from a mineshaft if you sent data at 1bit/year (not terribly
useful though ;) ).

Indeed.  a 75000km round trip for a single hop is 250 mS, more for multiple
satellite hops.

Same as we introduce by going 20km across town (10 up, 10 back), plus a
little more for processing delay.  IOW, nothing more significant than normal
local terrestrial latencies.
