I don't know much about the cost for network vs GPS chip but
the incurring cost for the GPS is on the customers side. They ( handset
manufacturer and telecom) design the spec, build it and sell it to the
customers. The cost of chip will be on the customer side. But I would
like to see how they actually make the information available, to what
extent, how and if it is available to the viewer's screen. ( in other
the customer could know where they are.)
The network solution is ambiguous... what if a user is in roaming
area? How does that work? It seems a bit complicated, they use
other network for global positions? puzzling... and again, if this
information is hidden in the background or the user could tell
their latitude and longitude?
Either way, they have to comply to the FCC E911 standard.
And I would even more be interetsed in seeing how they make
the cusomter opt-in available, how and in what way.
( in other words, if the customer doesn't mind its location
be revealed to whom and if they have ALL TIME control on
truning that off. This is the main issue in privacy advocate.)
