The procedure to configure (activate) your modem is covered
in
“Activation” on page 23.
The CDMA wireless network
Note: More information about
CDMA networks is available on
the CDMA Development Group
web site,
www.cdg.org
.
This is the worldwide infrastructure providing the radio
coverage that allows you to stay connected. Made up of radio
towers and a variety of network switches, routers, and servers,
the network is an interconnection of many service providers.
Note: Most service providers
have coverage maps on their
web sites. There are CDMA networks that operate in the frequency bands
supported by the modem throughout North America and
parts of Latin America, Asia, and New Zealand. However,
each service provider operates a network that covers a limited
geographical area within the overall CDMA coverage area.
Note: The fee for service is
usually higher when you are
roaming (connecting to a
network other than the one
belonging to your service
provider). Most service providers have “ roaming ” agreements with other
service providers, so that they can offer service outside of the
coverage area of their own networks. For example, assuming
you live in Vancouver (Canada), and travel frequently to
Seattle (United States), you can obtain an account with a
Vancouver service provider that has a roaming agreement with
a service provider in Seattle. You would then have local service
in Vancouver, and roaming service in Seattle.
Care and maintenance of your
modem
As with any electronic device, the modem must be handled
with care to ensure reliable operation. Follow these guidelines
in using and storing the modem:
• The modem should fit easily into your USB slot. Forcing
the modem into a slot may damage connector pins.
• When inserting or removing the modem, always grip it by
the sides rather than the end.
• Protect the modem from liquids, dust, and excessive heat.
• When not installed in your computer, store the modem in
a safe place.
