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.

You just read about All. A technology from the archive that helped get us here:
Google/Alphabet Project Loon served 2011–2021. What ultimately replaced it?
Google/Alphabet Project Loon solar-powered balloons drifting in the stratosphere (~20 km), steering by rising and falling into different wind layers, relaying LTE from ground stations to phones far below. Its job passed to Unit economics — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
