Lenovo ThinkPad Gobi 4000 Wireless Cellular Modem is a wireless WAN ready option that provides a remote access solution. Wireless WAN WWAN differs from a wireless LAN WLAN because it uses cellular network technologies such as WIMAX, CDMA, GSM, HSDPA, LTE, or 3G to transfer data. These cellular technologies are offered regionally, nationwide, and globally and are provided by a wireless service provider, typically for a monthly usage fee. WWAN is a predictable remote access solution.
