What is Wireless Full Duplex?
Wireless Full Duplex allows a radio to simultaneously transmit and receive overlapping signals using a single frequency channel. Imagine FDD performance within a single unpaired TDD channel, that's Wireless Full Duplex.

What Has Kumu Succeeded To Do?
Kumu has developed technology that cancels Self-Interference, the "unwanted" energy that leaks into a radio's receiver while transmitting. As a result of the cancellation, the receiver hears no noise from its transmitter, freeing it to cleanly receive external signals. A radio using Kumu's self-interference cancellation technology can transmit and receive at the same time on the same frequency.
Why Is This Important?
Self-Interference Cancellation revolutionizes the wireless world. Not only does it enable wireless full duplex, doubling the spectral efficiency of every radio in the world (an economic value of trillions of dollars), but it also tremendously simplifies spectrum management: currently an enormously complex task in the hand of regulators.
