How Does It Work?
Here’s a quick overview of how Globalstar data service works.
Cable
■ Connect your QUALCOMM Globalstar Tri-Mode Phone to the
computer or Palm handheld, using a QUALCOMM serial data cable
and any optional accessories.
Configure
■ Configure your computer or Palm handheld organizer to use Globalstar
data service (you need to do this only once for packet data, and once for
asynchronous data).
Connect
■ Click a data connection icon or menu on your computer.
■ The QUALCOMM Globalstar phone establishes a data connection to
the Globalstar Satellite Communications System or, for packet data
only, to a digital cellular network, using Point-to-Point Protocol (PPP).
Cruise a packet-switched network (packet data)
■ Open the application you want to use, for example an Internet browser
where you type in a Web address.
■ Your computer or Palm handheld sends data to the QUALCOMM
Globalstar phone, which transmits them either to a satellite and
Gateway in the Globalstar Satellite Communications System, or to a
digital cellular network.
■ For a Globalstar packet data call, packets are routed to and from your
network service provider through the Globalstar Satellite System, and
a router in the Globalstar Gateway connects to the Internet, as shown
in the following illustration.
