Mobile Broadband or Wireless Wide Area Network 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. What You Need to Establish a Mobile Broadband Network Connection To set up a Mobile Broadband network connection, you need: • A Mobile Broadband ExpressCard NOTE: For instructions on using ExpressCards, see "ExpressCards" on page 71.
