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.
