Wireless upgradeable ThinkPad models

Your computer can be wireless upgradeable. This means that your computer has an antenna that can support wireless LAN access when wireless LAN access points are available. Wireless devices are available from Lenovo. For more information, see “Finding ThinkPad options” on page 149.

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 244.

To use the wireless WAN feature, start Access Connections.

For maximum performance from your wireless WAN connection, please keep the following best usage guidelines in mind:

•Keep your notebook away from your body.

•Place your notebook on a flat surface and open your computer display to an angel of slightly more than 90 degrees.

•Place your notebook away from concrete or brick walls that may dampen cellular signals.

•Best reception will be available near windows and other locations where cellular phone reception is the strongest.
