Using The Wireless-Wan Connection; Using The Bluetooth Connection - ThinkPad T470 User Manual

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 1xEV-DO, HSPA, 3G, GPRS, 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.
For the Windows 7 operating system, you also can check the wireless-WAN connection status through the
Access Connections gauge in the Windows notification area. The more bars encompassed, the better
the signal is.
