Using the wireless-WAN connection
Wireless wide area network (WAN), which uses cellular networks for data transmission, enables you to
establish wireless connections over remote public or private networks. These connections can be maintained
over a large geographical area by use of multiple antenna sites or satellite systems maintained by wireless
service providers.
Some ThinkPad notebook computers come with a wireless-WAN card installed, which provides some
wireless-WAN technologies, such as HSPA, 3G, 4G, or LTE. By using the wireless-WAN card, you can
establish wireless-WAN connections.
Note: The wireless-WAN service is provided by authorized service providers in some countries or regions.
Tips for using the wireless-WAN feature
To achieve the best connection, use the following guidelines:
• Keep your computer away from your body.
• Place your computer on a flat surface and open your computer display to an angle of slightly more than 90
degrees.
• Place your computer away from concrete or brick walls that might dampen cellular signals.
• Best reception is available near windows and other locations where cellular phone reception is the
strongest.
Checking the wireless-WAN connection status
You can check the wireless-WAN connection status through the wireless-network-connection-status icon in
the Windows notification area. The more bars encompassed, the better the signal is.
