Buffalo Technology's Turbo G High Power products don't use MIMO at all, instead being based on Broadcom chipsets supporting "125 High Speed Mode" (originally Speedbooster) and "BroadRange" technologies. While Buffalo also has a higher-priced Airgo-based product, they are pushing their High Power line as a low cost alternative to MIMO. Unfortunately, price erosion of MIMO products is putting heavy pricing pressure on Buffalo's strategy, although they seem determined to maintain pricing enough below MIMO products to be alluring to prospective buyers.

D-Link's first attempt at MIMO with its DI-624M Super G with MIMO Wireless Router didn't exactly bring raves from reviewers and they wouldn't even provide product for me to test. But they got Atheros, which supplies its VLocity chipset, to go back to the drawing board, with the result being the DI-634M product they were happy to send for review.

Apparently most of the problems with D-Link's first MIMO attempt were in the router end, since the DWL-G650M card was also paired with the previous product.

NETGEAR's RangeMax products represent yet another twist on the MIMO theme, using Atheros Super-G chipsets and beam-forming antenna technology from Video54 (recently rebirthed as Ruckus Wireless). Of course, any product relying on Super-G's channel-bonding Turbo mode for high throughput won't produce peak speeds if any non Super-G gear is anywhere within range.
