Kumu Networks, which developed technology with the potential to double the capacity of wireless networks, has received $15 million in Series B funding led by Third Point Ventures, and joined by existing investors NEA and Khosla Ventures. Kumu raises $10 million in Series A funding from NEA and Khosla Ventures in December 2012, bringing total investment to $25 million.
Kumu Networks, a startup introducing technology able to double the capacity of any wireless network, has secured $15 million in Series B funding led by Third Point Ventures and joined by previous investors NEA and Khosla Ventures. Kumu previously raised $10 million in Series A funding from NEA and Khosla ventures in December 2012, bringing the total investment to $25 million to date.
Based on groundbreaking research from Stanford University, Kumu has created interference cancellation technology that allows radios to send and receive data at the same time on the same frequency, a feat previously considered impossible. The technology, known as Full Duplex wireless, is fundamental and applies to every radio (WiFi, LTE, etc) in every frequency band. Because of its potential to double the capacity of wireless networks, address spectrum fragmentation issues, and unify TDD and FDD standards into one coherent standard, this technology is currently being considered as a foundation for next generation 5G and High Efficiency WiFi standards.
“Many decades of incremental wireless technology developments and refinements have brought us close to what was thought to be the theoretical maximum efficiency of wireless spectrum,” said Robert Schwartz, managing director and partner at Third Point Ventures. “Kumu Networks has shattered this barrier and in the process opened up a massive new reservoir of capacity that will drive growth across every type of wireless networking and communications. We believe Kumu is about to change the industry.”
Even without any changes to the standards, Kumu’s Full Duplex technology can solve interference and spectrum fragmentation challenges that plague current 4G LTE and WiFi networks –creating billions of dollars of potential value for the wireless ecosystem. Specifically, Kumu allows existing radios to use any set of spectrum fragments simultaneously (carrier aggregation) without limitations of fixed hardware filters The technology also enables high capacity mesh networks, full duplex microwave backhaul links, high capacity multi-channel WiFi APs, and other valuable use cases that are completely within the boundaries of the current standards.
“Our technology revolutionizes radio design by changing a fundamental assumption about the handling of interference.” said Sachin Katti, Kumu Networks’ CEO and an Assistant Professor of EE & CS at Stanford University. “By eliminating all self-interference from inside the device we can, for the first time ever, allow a radio to transmit and receive at the same time on the same channel – effectively doubling the efficiency with which we can use one of the planet’s most valuable and finite resources – radio spectrum.”
The new funding will be used to further commercialize Kumu Networks’ Self-Interference Cancellation technology and support major carrier trials in early 2014.
