QUALCOMM Joins TGn Sync Proposal for 802.11n

QUALCOMM is joining TGn Sync, a cross-industry group that is developing an IEEE 802.11n standard proposal. Previously, QUALCOMM was separately responsible for one of the four remaining 802.11n system proposals that were submitted to IEEE for the development of the next generation of high-performance local area wireless networks.



QUALCOMM is now withdrawing its own proposal from the IEEE process and will back the TGn Sync proposal.



The 802.11n standard is expected to deliver wireless throughputs of 100 Mbps in home networks.



TGn Sync's proposal was developed under the guidelines of the IEEE Standards Association and submitted to the IEEE 802.11 Task Group N (TGn). The group said its proposal dramatically improves the capabilities of wireless networks while supporting the antenna configurations, product designs and protocol requirements of hundreds of millions of cellular handsets, enterprise base stations and Wi-Fi-enabled computers already in use worldwide.
http://www.qualcomm.com/http://www.tgnsync.net/In August 2004, two groups announced plans for joint proposal to the IEEE 802.11 Task Group N (TGn) for the next generation 802.11n standard.

TGn Sync is a coalition backed by Agere Systems, Atheros Communications, Cisco Systems, Intel Corporation, Marvell Semiconductor, Nokia, Nortel Networks, Royal Philips Electronics, Samsung Electronics, SANYO Electric Co., Sony and Toshiba. The companies said their TGn Sync specification would enable wireless LAN data rates to scale up to 243 Mbps in two-antenna designs and over 600 Mbps in larger systems. The proposal also includes methods to reduce power consumption for small mobile phones and increase the user capacity of public networks. The proposal also uses adaptive radio techniques to ensure that wireless products can adjust to the planned expansion of unlicensed and licensed spectrum in China, Japan, South Korea, North America, the European Union (EU), and other regions.

The "WWiSE" consortium is backed by Airgo Networks, Bermai, Broadcom, Conexant Systems, STMicroelectronics and Texas Instruments. Its proposal would support data throughput in excess of 100Mbps while building upon and extending the capabilities of Wi-Fi. It would specify mandatory modes affording backwards compatibility and interoperability with existing Wi-Fi devices in the 5 GHz and 2.4 GHz bands .
