LONDON Ė 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."
