“Kumu Networks”, a startup formed by Stanford University 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. (i-e Wireless Full Duplex System)
Wireless Full Duplex allows a radio to simultaneously transmit and receive overlapping signals using a single frequency channel
Kumu networks says, “Imagine FDD performance within a single unpaired TDD channel, that’s Wireless Full Duplex. ”
Kumu networks highlights the importance of this new technology by saying,
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.
Kumu claims that its Self-Interference Cancellation is applicable to a host of Horizontal Wireless Technologies without Standards Modifications. It it is listing below things.
- 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.
- High Capacity Dense WiFi – 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 active remote IED explosives while preserving radio communication between friendlies
“Kumu Networks” was founded in 2012 by a team of Stanford University Professors and Ph.D graduates with a mission to commercialize research on Wireless Full Duplex. It is funded by Venture Investors New Enterprise Associates and Khosla Ventures. Many Stanford professors did Angel investments for creating the “Kumu Networks”.
