I guess that what's new in this is a feature that tries to minimize,
automatically, the correlation between the different multipaths, in 802.11n.
Through beamforming. Where otherwise, you're just going to get whatever
bandwidth the multipath environment allows.
I wonder what effect this would have on the new 60 MHz schemes? I prefer this
approach.

HD-over-Wi-Fi startup raises $21 million

LONDON - Quantenna Communications Inc., a developer of silicon for wireless
networking that adds beamforming to the 802.11n wireless standard to deliver
guaranteed bandwidth, has raised $21 million in a Series E round of financing
just six months after the company closed a $15 million D round.
The latest round was led by new investor DAG Ventures, with participation from
the existing investors Sequoia Capital, Sigma Partners, Southern Cross Venture
Partners, and Venrock Associates.
The money will be used to accelerate the deployment of 4 x 4 MIMO 802.11n Wi-Fi
chipsets through carriers and retail channels worldwide, Quantenna (Fremont,
Calif.) said.
In addition to incorporating all specifications of the IEEE802.11n standard
including 4 x 4 MIMO, the chipset incorporates extensions to the IEEE802.11n
standard including dynamic digital beamforming, wireless channel monitoring and
optimization. These features enable Wi-Fi home networks to deliver the same
quality as wired Ethernet while guaranteeing compatibility with existing and
future IEEE 802.11n-compliant products.
The company's Full-11n chipsets allow the distribution of multiple
high-definition (HD) video streams throughout the home at full, 1080p
resolution.
"Quantenna's unique video-over-Wi-Fi value proposition has broad and growing
appeal, and the company is poised to scale revenue as leading service providers
launch advanced video offerings, worldwide," said Nicholas Pianim, managing
director with DAG Ventures, who joins Quantenna's board of directors.
"802.11n technology will play a critical role in the broad adoption of
Internet-enabled living room devices that we forecast to grow at a 34.1 percent
CAGR to 430 million units in 2014; up from 99.3 million in 2009," said Jordan
Selburn, principal analyst for consumer platforms, with market research firm
iSuppli Corp. (El Segundo, Calif.) "Successful deployment of Internet-enabled
TVs, video game consoles and set-top boxes requires a network capable of
reaching any point in the home with ultra-high reliability, performance and low
latency, with bandwidth and levels of Quality of Service sufficient for
high-definition video. Advancements in 802.11n technology will position this
approach to become a leader in home multimedia networks."
