Cisco, Wireless Ops Back $25M in Kumu Funding

SUNNYVALE, Calif. -- Full Duplex inventor Kumu Networks today announced it has secured $25 million in a Series C funding round from Cisco, Verizon Ventures, Deutsche Telekom Strategic Investments, and Swisscom. A powerful new development that doubles the capacity of existing wireless spectrum, Kumu Networks’ Full Duplex technology is being explored as an enhancement to existing LTE deployments and as a potential addition to next generation 5G standards. Previous investors NEA, Third Point Ventures and Khosla also joined the round.

“Kumu Networks’ Full Duplex technology is a rare technological breakthrough that offers substantial benefit to a multitude of wireless modalities,” said Rachid El Hattachi, SVP Architecture and Blueprints at Deutsche Telekom. “Full Duplex offers significant advantages and removes roadblocks from wireless endeavors as diverse as LTE Advanced, general Radio Frequency planning and future standards and protocols. We jumped at a chance to invest in and help foster this important new technology.”

Kumu Networks’ Full Duplex technology cancels self-interference allowing a radio for the first time in history to transmit and receive at the same time on the same frequency. By eliminating the "unwanted" energy that leaks into a radio's receiver while transmitting, Full Duplex is able to double the spectral efficiency of wireless systems - an economic value of trillions of dollars – and has also been identified as a foundational technology that will address some of the critical challenges facing next generation networks.

“We are honored to have such a broad coalition of investors participating in our Series C funding,” said Kumu Networks CEO David Cutrer. “The diverse group of investors highlights the broad reach and economic potential of our solution and its massive impact on multiple arenas within the wireless industry.”

Full Duplex and Self-Interference Cancellation technologies have the potential to double spectral efficiency in any wireless setting. Even in current LTE networks, these technologies facilitate the introduction of In-Band Full-Duplex Relay Nodes that allow operators to cost-effectively densify their network while leveraging their own LTE spectrum for backhaul. Such network densification is the key to addressing the ever increasing demand for wireless data.

Kumu Networks currently has field tests, trial deployments or research partnerships with a broad array of global Tier 1 wireless carriers including Deutsche Telekom, SK Telecom, Telefonica, and TIM. The Series C funding will be used to further develop and deploy Kumu Networks’ core product lineup.
