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 33, 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.
