Intel's upcoming Montevina mobile platform (due 2008) will support WiMAX
From ars technica reporting on the Intel Developer Forum in Beijiing
WiMAX coming to Intel laptops in 2008:
Montevina is currently targeted for the first half of 2008 and will be the successor to Santa Rosa, which is due to arrive next month. We touched on Santa Rosa last month, which will include support for Intel Turbo Memory Technology (aka, Robson), built-in 802.11n Draft 2.0 capability, support for vPro under the Centrino Pro brand, and Advanced Management Technology, all rolled into a new chipset.
Intel's betting on widespread availability of WiMAX is bolstered by Sprint's plan to rollout WiMAX, also in 2008:
Working together with Intel, Motorola and Samsung, Sprint Nextel will develop a nationwide network infrastructure as well as mobile WiMAX-enabled chipsets that will support advanced wireless broadband services for computing, portable multimedia, interactive and other consumer electronic devices. These efforts are intended to allow Sprint Nextel customers to experience a nationwide mobile data network that is designed to offer faster speeds, lower cost, and greater convenience and enhanced multimedia quality.
