What is wwan option

WWAN can all but guarantee connectivity when the user needs it. To take advantage of this technology, a user must first purchase a WWAN PC card for his or her laptop unless the connectivity is built-in. By purchasing the card and paying a monthly fee, the user only needs to slip the card into the PC-card slot sometimes known as the PCMCIA slot to access the service.

Plans vary among providers but most are rated according to data download caps. Some providers have plans that allow users to pay by the day for connectivity. By using the WWAN card, the person commits to a small charge, securing a hour pass. At the end of the hour period, the user can no longer connect, unless he or she purchases another pass. The cell phone acts as a modem to patch the laptop into the Internet.
