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” on page 21
