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
t
he
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
59.
•
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
