Wi-Fi Net News is reporting that Draft 1.0 of 802.11n standard was approved yesterday.
In January 2004 IEEE announced that it had formed a new 802.11 Task Group (TGn) to develop a new amendment to the 802.11 standard for local-area wireless networks. The real data throughput is estimated to reach a theoretical 540 Mbit/s (which may require an even higher raw data rate at the physical layer), and should be up to 40 times faster than 802.11b, and near 10 times faster than 802.11a or 802.11g. It is projected that 802.11n will also offer a better operating distance than current networks.
There were two competing proposals of the 802.11n standard: WWiSE (World-Wide Spectrum Efficiency), backed by companies including Broadcom, and TGn Sync backed by Intel and Philips.
Previous competitors TGnSync, WWiSE, and a third group, MITMOT, said in late July 2005 that they would merge their respective proposals as a draft which would be sent to the IEEE in September; a final version will be submitted in November. The standardization process is expected to be completed by the second half of 2006.
802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input multiple-output). MIMO uses multiple transmitter and receiver antennas to allow for increased data throughput through spatial multiplexing and increased range by exploiting the spatial diversity, perhaps through coding schemes like Alamouti coding.
The Enhanced Wireless Consortium (EWC)  was formed to help accelerate the IEEE 802.11n development process and promote a technology specification for interoperability of next-generation wireless local area networking (WLAN) products.
On January 19, 2006, the IEEE 802.11n Working Group approved the EWC's specification as the draft approval of 802.11n.
Wi-Fi Networking News: Breaking News: 802.11n Draft 1.0 Approved
Breaking News: 802.11n Draft 1.0 Approved By Glenn Fleishman The IEEE approved draft 1.0 of 802.11n yesterday: The IEEE voted in January to accept a proposalâ€”largely that of the Enhanced Wireless Consortium with some changesâ€”as a pre-1.0 draft. That near-unanimous vote was the first step in finalizing 802.11n, which has been under discussion for years and which appeared to be heading to a deadlock. The EWC proposal was quietly built by four chipmakersâ€”Atheros, Broadcom, Intel, and Marvellâ€”and then sold back into a joint proposal group that was trying to harmonize competing efforts.
