Introducing the AirCard® 580 Wireless WAN Modem
Each service provider has its own pricing options. There may
be flat rate accounts, which provide you a maximum number
of minutes of network usage for a fixed monthly fee. There
may be accounts for which you are charged for network usage
by the minute or by the amount of data transmitted.
Your account may include a variety of other services such as
SMS messaging.
Each AirCard has been provisioned at the factory for use with
a particular service provider. This sets the AirCard to use
particular radio channels and enables services specific for that
provider.
The process of setting up your account is called activation.
Activation involves action by the service provider and configu‐
ration of the AirCard.
The procedure to configure (activate) your AirCard is covered
in "Activation" on page 19.
The CDMA wireless network
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.
.
There are CDMA networks that operate in the frequency bands
supported by the AirCard throughout North America and
parts of Latin America, Asia, New Zealand, and Australia.
However, each service provider operates a network that covers
a limited geographical area within the overall CDMA coverage
area.
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 and travel frequently to Seattle, 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.
