IEEE 802.11n Task Group Favors TGn Sync Proposal

The IEEE 802.11n Task Group voted to eliminate one of the two remaining 802.11n proposals for next generation Wi-Fi capable of speeds well in excess of 100 Mbps.

The Task Group voted: 181 in favor of the TGn Sync proposal and 140 in favor of the WWiSE proposal. According to Atheros, with the WWiSE proposal eliminated from consideration, the next step is a second confirmation vote in May. During which a 75% supermajority is required to approve TGn Sync's proposal as the final 802.11n standard.

Backers of the TGn Sync proposal included Agere Systems, Atheros Communications, Cisco Systems, Intel Corporation, Marvell Semiconductor, Nokia, Nortel Networks, Royal Philips Electronics, Samsung Electronics, SANYO Electric Co., Sony, Toshiba and Qualcomm. In previous briefings, the group has claimed its 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.

Members of the WWiSE consortium included Airgo Networks, Bermai, Broadcom, Conexant Systems, STMicroelectronics and Texas Instruments.
