802.11n Wireless Standard No.2
Posted: 17th Aug, 2004 By: MarkJ
Following on from last weeks submission by the WWiSE group, a second potential standard for 802.11n wireless has just been proposed, this time by the TGn Sync consortium. The new template aims for a technology that can offer up to 600Mbps+:
TGn Sync comprises the likes of Intel, Atheros, Cisco, Nokia, Nortel, Sony, Philips, Samsung and Toshiba, among others. Their joint proposal not only defines Wi-Fi technology capable of reaching 600Mbps and beyond, they claim, with a basic throughput of 243Mbps, but utilises adaptive radio technology to automatically adjust each radio to meet the regulatory structure of different territories.
Like the WWiSE group, TGn Sync's 802.11n proposal is based on the Multiple Input, Multiple Output (MIMO) many-antennae technique and Orthogonal Frequency Division Multiplexing (OFDM) to boost data throughput rates.
It too proposes support for 20MHz and 40MHz channel widths, for backward compatibility with today's Wi-Fi kit and room for high-bandwidth networks, respectively. It also includes a 10MHz channel width, and like WWiSE is based on two- and four-antenna arrays.
Sadly you won't see such technology for a few years yet, with some analysts pointing towards final ratification during 2007. More @ The Register.
