Quantenna Communications Raises $14 Million in Series C Funding for Wireless High Definition Home Networking

FREMONT, CA--(Marketwire - April 29, 2009) - Quantenna Communications, Inc., a leading developer of silicon for high-speed, multimedia wireless networking, today announced that it has received $13.85 million in Series C funding led by new investor Southern Cross Venture Partners, with participation from existing investors Grazia Equity GmbH, Sequoia Capital, Sigma Partners and Venrock Associates. In addition, Southern Cross Venture Partners Managing Director Dr. Larry Marshall has joined Quantenna's board of directors. With this latest round, total investment in the three-year old wireless semiconductor company now exceeds $42 million.

Quantenna is focused on solving today's home networking challenges. These challenges include delivering ultra-reliable, high-speed wireless coverage throughout the whole home to support sharing of high definition (HD) video and multimedia content between home gateways and TVs anyplace, anywhere. Quantenna's technology is targeted at devices such as home residential gateways, set-top boxes, routers, HDTVs and consumer electronic devices, which all require high bandwidth and reliability to support whole home HD video distribution and networking over standard Wi-Fi networks.

"In this tough economic environment, we looked at many wireless companies and found that Quantenna was leading the way with the next generation of wireless MIMO technology and an outstanding engineering team, while generating substantial interest from the industry's top consumer electronic manufacturers," said Dr. Larry Marshall, managing director at Southern Cross Venture Partners. "The company's significant lead in next-generation, standards-based Wi-Fi home networking, coupled with the rapid adoption of wirelessly distributing multimedia content throughout the home, presented a great investment opportunity for us."

Quantenna plans to use the Series C funding to solidify its market position as the wireless networking semiconductor vendor of choice for manufacturers looking to deliver standards-based, real-time HD video distribution for next-generation HD gaming, multimedia and entertainment throughout the connected home. The new funding also will be used as working capital to help the company expand sales and engineering activities and support increased production of its wireless networking solutions.

"Clearly, our new and existing investors recognize the exceptional investment opportunity of Quantenna, as our wireless technology will enable both carriers and consumer electronic manufacturers as they compete for who will control the digital living room," said Behrooz Rezvani, Quantenna's chairman of the board. "This new funding underscores the tremendous value our 4x4 MIMO and dynamic digital beamforming technology can offer to home networks, as well as our ability to win customers and gain significant market share in a highly competitive wireless networking market."

Quantenna's HD Wi-Fi Technology

Quantenna chipsets are the first fully integrated, standards-based, 802.11n/Wi-Fi chipsets with 4x4 multiple input/multiple output (MIMO) technology and dynamic digital beamforming. These chipsets are designed to deliver dramatically higher levels of Wi-Fi performance, while meeting the growing need for increased speed, reliability and complete home coverage for HD Wi-Fi home networking.

Quantenna's unique combination of technologies effectively achieves improvements of up to four times the coverage and as much as twice the throughput of existing solutions on the market. Next generation Wi-Fi networks that combine 4x4 MIMO -- which use four radio transceivers and four antennas -- with dynamic digital beamforming at the chip level will have a distinct performance advantage over current technology on the market. This advantage results from the fact that a 4x4 MIMO system that supports two data streams can provide two extra antennas for beamforming, which adds an extra dimension of reliability per data stream. When combined, these technologies can deliver system gains in the 12 to 25 dB range.

By integrating 4x4 MIMO with dynamic digital beamforming, the chipsets are adaptive and dynamically adjust to conditions in the milliseconds time frame. The chip's DSP coupled to four antennas are communicating and making constant on-chip transmitter and receiver adjustments in real time. This provides a number of important benefits for delivering wireless HD and multimedia content over standard home Wi-Fi networks. These benefits include:

--  Intelligent high-speed performance and consistency anywhere in the
    home, even hard to reach corners; and
--  Ultra-reliable connectivity with interference rejection.
