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, such as a city or an entire country, by use of multiple antenna
sites or satellite systems maintained by wireless service providers.
Some ThinkPad notebook computers come with a built-in wireless WAN card integrated with some wireless
WAN technologies, such as 1xEV-DO, HSPA, 3G, GPRS, or LTE. By using the built-in wireless WAN card and
the configuration utility that comes with your computer, you can establish wireless WAN connections and
monitor the connection status.
Note: The wireless WAN service is provided by authorized service providers in some countries.
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 lid 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 will be available near windows and other locations where cellular phone reception is the
strongest.
