Kumu Networks, a start-up based in Sunnyvale, California, raised $25 million in series C funding for its full-duplex wireless technology.
Kumu enables a radio to simultaneously transmit and receive overlapping signals using a single frequency channel. It accomplishes this using self-interference cancellation technology.
The new round was led by Cisco with participation from Verizon Ventures and Deutsche Telekom. Existing investors include NEA, Third Point Ventures and Khosla Ventures.
Kumu Networks: Opening the Door to Full Duplex Wireless
Born out of a class project at Stanford University, Kumu Networks is commercializing self-interference technology and full-duplex wireless. In this video, co-founder Steven Hong explains how radio self-interference has been a problem since the earliest days of wireless communications. The Kumu approach is the first to cancel out this interference by subtracting the transmitter’s signal from its own receiver.
Kumu Networks, backed by top venture firms in Silicon Valley, now aims to apply its technology to applications such as small cell backhaul. In field testing, Kumu significantly boosts spectral efficiency.
