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.

Full Duplex Wireless Backhaul
Self-Interference Cancellation doubles wireless capacity and reduces spectrum requirements for wireless backhaul solutions
Self-Backhauled Small Cell
With Self-Interference Cancellation, the access and backhaul radios can operate simultaneously on the same frequency, allowing the small cell to backhaul itself while maintaining end-end throughput
Self-Interference Cancellation increases WiFi throughput and resiliency in dense and crowded environments without any change to existing clients
Global Spectrum Harmonization
Self-Interference Cancellation acts as a software configurable filter, facilitating global LTE roaming by enabling cellular infrastructure and mobile phones to support multiple frequencies and carrier aggregation
TV White Space Spectrum Sharing
Self-Interference Cancellation acts as a software configurable filter, empowering a radio to aggregate any random collection of channels and enabling high throughput applications in fragmented shared spectrum
Radio Jamming and Security
Self-Interference Cancellation can save lives in the battlefield - jamming enemy radios which are used to activate remote IED explosives while preserving radio communication between friendlies
