WiMAX coming to Intel laptops in 2008
| 23 мая 2007 |
Intel will support WiMAX and 802.11b/g/n on the same piece of silicon (called Echo Peak) with Montevina, but will also offer a WiMAX-only card. Montevina will still feature the Core 2 Duo CPU, but fabbed at the 45nm process and containing up to 6MB of shared L2 cache.
Intel had planned to bring support for High-Speed Downlink Packet Access (HSDPA) to Santa Rosa, which would have enabled laptops with that chipset to access many 3G networks out of the box and allow for seamless transitions between 802.11b/g/n and 3G networks. Those plans changed earlier this year, when Nokia and Intel decided that the potential return on investment from supporting HSDPA didn't justify the development effort.
WiMAX has been slow to get off the ground, but Intel apparently believes that WiMAX access will be widespread enough to justify supporting it. In the US, Sprint plans to begin offering WiMAX in early 2008 in a number of US cities.
Montevina will likely support 802.16e-2005, which is better known as Mobile WiMAX. Users should see average download speeds of 2-4Mbps, at least on Sprint's WiMAX network. Down the road, Intel will likely add support for 802.16m, or "gigabit WiMAX," which offers speeds of up to 1Gbps per channel, but the 802.16m standard is unlikely to be officially ratified by the IEEE before early 2009.
