•If you use the wireless feature (the 802.11 standard) of your computer simultaneously with a Bluetooth option, the data transmission speed can be delayed and the performance of the wireless feature can be degraded.

Wireless WAN

Wireless Wide Area Network (wireless WAN), using 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 integrating 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 status of your connection.

Note: 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 display to an angel 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.

WiMAX

Some ThinkPad notebook computers come with a built-in wireless LAN card integrating WiMAX technology.

This long-range wireless data transmission technology based on the 802.16 standard is expected to provide the user a “last mile” broadband connectivity similar to that provided by cable or ADSL, but without the need to physically connect a cable to the personal computer.

Bluetooth

Bluetooth is one of a number of technologies used to create a wireless personal area network. Bluetooth can connect devices a short distance from one another, and is commonly used for connecting peripheral devices to a computer, transferring data between hand-held devices and a personal computer, or remotely controlling and communicating with devices such as mobile phones.

Establishing wireless connections

To establish a wireless connection, do the following:

1.Press Fn+F5 to turn on the wireless feature.

2.Click the wireless network connection status icon in the Windows notification area. A list of available wireless networks is displayed.

3.Double-click a network to connect to it. Provide required information if needed.

If you need to connect to different wireless networks in different locations, use the following software to manage multiple network profiles so that the computer connects to an available network automatically when the location changes:
