Technology company Kumu Networks has won a $1.5m task order from the US Army for a Phase II small business innovation research (SBIR) project.
The company will use its Self-Interference Cancellation platform to develop more than 100dB Full-Duplex Module, which will be the highest performing module created so far.
Under the project, Kumu’s ‘Self-Interference Cancellation’ technology will be integrated to develop radios capable of suppressing in-band self-interference from friendly, co-located jammers.
The devices will also be able to eliminate interference from non-co-located enemy jammers.
These radios will provide troops with the ability to freely transmit to friendly forces while jamming enemy transmissions at the same time.
The US Army Program of Record Office intends to focus on incorporating this capability into multiple production handheld, manpack and small form-fit (HMS) radios.

The Kumu-developed solution will be used in existing vehicle-mounted and manpack military radios.
The deployed technology will increase the spectral efficiency of field-deployed radios, doubling throughput, and simultaneously operating co-located in-band jammers.
Kumu Networks CEO David Cutrer said: “One of the biggest communications challenges for army warfighters is to operate in congested, contested and denied environments.
“Minimising self-interference from friendly and enemy jammers is a key enabler for the current and future connected battlefield.”
According to the company, the current Kumu Full-Duplex modules already deliver approximately 80dB.
As the prime contractor of the project, Kumu will further incorporate ‘MIT Lincoln Laboratory adaptive antenna cancellation and receive beamforming’ technology to achieve over 100dB of cancellation.
MIT Lincoln Laboratory assistant group leader Bradley Perry said: “MIT Lincoln Laboratory is leveraging previous efforts funded by the Office of Naval Research by combining receive beamforming with antenna cancellation technology developed as part of those efforts with Kumu’s analogue and digital cancellation technology to deliver more than 100dB of self-interference cancellation, one of the highest levels reported to date.
“In a wirelessly connected battlefield, the ability to operate free of radio self-interference concerns creates a critical asymmetrical advantage for our nation’s fighting forces.”
