Some ThinkPad notebook computers come with a built-in wireless WAN card integrating some wireless
WAN technologies, such as 1xEV-DO, CDMA, HSPA, HSPA+, 3G or GPRS. 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.
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.
Tips for using the wireless connection features
To achieve the best connection, use the following guidelines:
• Keep your computer away from your body.
• Place your computer so that there are as few obstacles as possible between the wireless LAN access
point and the computer.
• Open your computer display to an angle slightly greater than 90 degrees.
• 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.

your computer wireless features before boarding. .
