Using Bluetooth - Lenovo ThinkPad T420si User Manual

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.
