Quantenna Raises $15 Million in Series D Financing Round

Current Investors Fund Cash Infusion To Support Rapid Growth in Customer Demand for Company’s Full-11n™ 4x4 MIMO Wi-Fi Wireless Chipsets

FREMONT, Calif., Feb. 24, 2010 - Quantenna Communications, Inc., a leader in ultra-reliable Wi-Fi networking for whole-home entertainment, today announced that it has raised $15 million Series D round of financing from its current strong investors Grazia Equity, Sequoia Capital, Sigma Partners, Southern Cross, Swisscom, and Venrock Associates. The cash infusion will enable the company to accelerate volume production ramp so it can meet rapidly growing customer demand for its Full-11n 4x4 Multiple Input Multiple Output (MIMO) Wi-Fi chipsets, which deliver the highest levels of performance and reliability for wireless networks and devices.

“Because of its increasing presence in CE devices, as well as its ubiquity in mobile PCs, Wi-Fi is in an excellent position to become the multimedia interface of choice for consumer entertainment devices. In order to maintain its successful cast, it must handle video reliably,” said Brian O’Rourke, principal analyst with In-Stat. “Quantenna’s technology is extremely impressive, and delivers remarkable video networking quality. This is an enormous market opportunity, with total Wi-Fi chipset revenue expected to pass $4 billion by 2012.”

“This is an exciting chapter for Quantenna, as we work with some of the industry’s leading consumer electronics manufacturers to deploy a new generation of ultra-high-reliability Wi-Fi home-networking products that can distribute multiple video streams throughout the home at full, 1080p resolution,” said David French, Quantenna’s CEO. “We have a rapidly growing design pipeline encompassing a wide variety of exciting new products and services, all based on our industry-standard IEEE 802.11n technology with super-charged video capabilities.”

“This financing round enables us to accelerate production shipments to customers for retail deployments, and also showcases the high level of continuing investor confidence in our superior market position and extremely attractive growth opportunities,” said Behrooz Rezvani, Quantenna’s founder and chairman. “Quantenna continues to be the only player with 4x4 MIMO Wi-Fi solutions that feature digital beam forming and other key features, in a home entertainment networking market where anything less than full HD quality with 1080p resolution simply will not satisfy consumer quality expectations or carrier reliability demands.”

Quantenna’s Full-11n chipsets are the only devices to incorporate the full range of IEEE802.11n specifications including 4x4 Multiple Input Multiple Output (MIMO), dynamic digital beamforming, and wireless channel monitoring and optimizing. They ensure that Wi-Fi home networks can deliver the same quality as wired Ethernet, including supporting up to full HD video with 1080p resolution, anywhere in the home, while guaranteeing compatibility with existing and future IEEE 802.11n-compliant products.
