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 a Mini-Card or an ExpressCard with PCMCIA adapter to
establish a Mobile Broadband network connection.
To set up a Mobile Broadband network connection, you need:
• A Mini-Card
• A Subscriber Identity Module (SIM) or an activated card for your service provider
NOTE: Only Cingular and Vodafone need a SIM card. Verizon, Sprint, and Telus do not use a SIM.
• The Dell Mobile Broadband Card Utility (already installed on your computer if you purchased the card
when you purchased your computer, or on the CD 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 for instructions. The user’s guide is available through the Windows Help and Support
Center (click Start→ Help and Support) or on the CD that accompanied your card if you purchased
it separately from your computer.

Depending on what you selected when you purchased your computer, the computer has a variety of
configurations. To determine your computer configuration, see one of the following:
