Intel Reaffirms Support for TGn Sync Alliance

Company says it backs the alliance's approach to achieving 100+Mbit/sec throughput in future-generation wireless networks.

In a talk about the current status of its 802.11n efforts, Intel reaffirmed its backing of the TGn Sync Alliances approach to achieving 100+Mbit/sec throughput in future-generation wireless networks. This presentation gave a high-level technical overview to several approaches under consideration as the best blend of performance and cost in the final 802.11n spec, due in 2007. Specifically, the IEEE Task Group N (TGn) is considering which carrier frequencies to use: The two currently under consideration are 20MHz and 40MHz.
The latter can deliver better performance at a lower cost since it requires fewer antennas and less-expensive radios.
Using the 40MHz carrier, researchers have been able to achieve top throughputs of around 240Mbits/sec, although taking into account regulatory constraints, this figure drops to about 140Mbits/sec. One of the key components to enabling the targeted 5X performance increase over current-generation 802.11 technology is MIMO (multiple-in, multiple-out) achieved via SDM (spatial division multiplexing). This differs from the approach espoused by the WWiSE (World-Wide Spectrum Efficiency), which includes chip-set makers Motorola, TI, Broadcom and Airgo.

Dave came to have his insatiable tech jones by way of music—,and because his parents wouldn't let him run away to join the circus. After a brief and ill-fated career in professional wrestling, Dave now covers audio, HDTV, and 3D graphics technologies at ExtremeTech.

Dave came to ExtremeTech as its first hire from Computer Gaming World, where he was Technical Director and Lead (okay, the only) Saxophonist for five years. While there, he and Loyd Case pioneered the area of testing 3D graphics using PC games. This culminated in 3D GameGauge, a suite of OpenGL and Direct3D game demo loops that CGW and other Ziff-Davis publications, such as PC Magazine, still use.

Dave has also helped guide Ziff-Davis benchmark development over the years, particularly on 3D WinBench and Audio WinBench. Before coming to CGW, Dave worked at ZD Labs for three years (now eTesting Labs) as a project leader, testing a wide variety of products, ranging from sound cards to servers and everything in between. He also developed both subjective and objective multimedia test methodologies, focusing on audio and digital video. Before all that he toured with a blues band for two years, notable gigs included opening for Mitch Ryder and appearing at the Detroit Blues Festival.
