Well, that shouldn't be a problem, as the GPS signal comes from
satellites in orbit, not from any ground-based towers.

Which is fine when away from tall buildings.
Unfortunately, in cities where the buildings are mostly 10 stories
or taller, the GPS signals are blocked.

Ah, but many phones with GPS receivers require a connection to the network to do
the processing of the signals and calculate the location.

Ah, that's interesting. And, dare I say it, a bit bloody useless if
you're out of range of the cellular signal.

Hmm. I'm going to look into this a bit more. Thanks for the information.
