Right, with a strong emphasis on the "and" in "(from you ***and*** its
base station, remember)".  So that's a minimum of ~80,000 miles round
trip.  That is a bloody long ways to go.  And hopefully you've only got
one hop to go (a safe assumption if the receiver is in the USA).  Then
you've still got to be routed through a last mile land line to the
telco's switch, then to an MAE, then to where you actually want to
reach.  Those last steps can be painful enough using DSL! 

If satellites were such a great bi-directional communication method, why
are there fleets of submarines used to lay fiber cable across the ocean
floor?
