Note: If you use the wireless feature (the 802.11 standard) of your computer simultaneously with a Bluetooth
option, data transmission speed can be delayed and the performance of the wireless feature can be
degraded.
Using WiMAX
Some ThinkPad notebooks come with a built-in wireless LAN card integrating WiMAX technology.
WiMAX, a long-range wireless data transmission technology based on the 802.16 standard, provides you
with a "last mile" broadband connectivity similar to that offered by cable or ADSL, but without the need to
physically connect a cable to the PC.
To use the WiMAX feature, start Access Connections.
For Windows 7: To start the Access Connections wizard, see "Accessing applications in Windows 7" on
page 18, and follow the instructions on the screen.
For Windows Vista and Windows XP: To start the Access Connections wizard, click Start ➙ All Programs ➙
ThinkVantage ➙ Access Connections. Then follow the instructions on the screen.
