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 79.
• An activated Mobile Broadband ExpressCard or activated Subscriber
Identity Module (SIM) for your service provider
• The Dell Mobile Broadband Card Utility (already installed on your
computer if you purchased the card when you purchased your computer, or
on the media that accompanied your card if purchased separately from
your computer)
If the utility is corrupted or deleted from your computer, see the Dell
Mobile Broadband Card Utility user’s guide in Windows Help and
Support
(click Start
, and then click
Help and Support)
or on the
media that accompanied your card if you purchased it separately from your
computer.
