Using wireless WAN connections Wireless Wide Area Network (wireless WAN) enables you to establish wireless connections over remote public or private networks. These connections can be maintained over a large geographical area, such as a city or an entire country, by use of multiple antenna sites or satellite systems maintained by wireless service providers. Some ThinkPad notebooks come with a built-in wireless WAN card integrating some wireless WAN technologies, such as 1xEV-DO, HSPA, 3G or GPRS. You can connect to the Internet or your company network with the built-in wireless WAN card and the configuration utility to make a wireless WAN connection and monitor its status. Note: Wireless WAN service is provided by authorized service providers in some countries. To find the location of the wireless WAN antenna on your computer, refer to "Location of the UltraConnect wireless antennas" on page 216. To use the wireless WAN feature, start Access Connections.
