Mobile Broadband (WWAN)

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.

Establishing a Mobile Broadband Network Connection

NOTE:
Depending on your computer, you can use either a Mobile Broadband PC Card or ExpressCard to establish
a Mobile Broadband network connection.
To set up a Mobile Broadband network connection, you need:
• A Mobile Broadband PC Card or ExpressCard
NOTE:
For instructions on using PC Cards or ExpressCards, see "Using Cards" on page 67
• An activated Mobile Broadband PC Card or 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 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 by clicking Start or
Support, or on the CD that accompanied your card if you purchased it separately from your computer.
