Mobile Broadband (or Wireless Wide Area
Network)
A Mobile Broadband network, also known as a Wireless Wide Area Network
(WWAN), is a high-speed digital cellular network that provides Internet
access over a much wider geographical area than a WLAN, which typically
covers only from 100 to 1000 feet. Your computer can maintain Mobile
Broadband network access as long as the computer is within a cellular-data
coverage zone. Contact your service provider for coverage of a high-speed
digital cellular network.
NOTE:
Even if you are able to make a call from your cellular phone in a specific
geographical location, that location may not necessarily be within a cellular-data
coverage zone.
What You Need to Establish a Mobile Broadband Network Connection
NOTE:
Depending on your computer, you can use either a Mobile Broadband
ExpressCard or Mini-Card, but not both, to establish a Mobile Broadband network
connection.
To set up a Mobile Broadband network connection, you need:
• A Mobile Broadband ExpressCard or Mini-Card (depending on your
computer’s configuration)
NOTE:
For instructions on using ExpressCards, see "Using ExpressCards" on
page 91.
• An activated Mobile Broadband ExpressCard or activated Subscriber
Identity Module (SIM) for your service provider
