Setting Up and Using Networks
Mobile Broadband or Wireless Wide Area Network (WWAN)
Much like a WLAN, a Mobile Broadband network (also known as a WWAN) is a series of interconnected
computers that communicate with each other through wireless technology. However, a Mobile
Broadband network uses cellular technology and therefore provides Internet access in the same varied
locations from which cellular telephone service is available. Your computer can maintain the Mobile
Broadband network connection regardless of its physical location, as long as the computer remains in the
service area of your cellular service provider.
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). For
instructions on using ExpressCards, see "Using Cards" on page 61.
• 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 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 (or on the CD that accompanied your card if you purchased it separately from your computer).
To access the Help and Support Center, see "Windows Help and Support Center" on page 12.
Checking Your Mobile Broadband Card
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:
• Your order confirmation
• Microsoft Windows Help and Support Center
To check your Mobile Broadband card in the Windows Help and Support Center:
1 Click Start→ Help and Support→ Use Tools to view your computer information and diagnose
problems .
2 Under Tools, click My Computer Information→ Find information about the hardware installed on
this computer.
On the My Computer Information - Hardware screen, you can view the type of Mobile Broadband card
installed in your computer as well as other hardware components.
