Military wants to move cognitive radio from concept to reality

The Joint Tactical Radio Systems (JTRS) office responsible for developing radio components and software that enable the military services to communicate with each other on the battlefield is moving closer to achieving the concept of cognitive radio, reports the Army.

Cognitive radio refers to the effort to field software programmable radio in a way that makes the best use of available spectrum. Through this approach, JTRS radios would efficiently draw upon high-bandwidth waveforms, ensure maximum interoperability among deployed forces and preserve the security of voice, data and video transmitted  in real time, the story said.

A key element of the development of JTRS Cognitive Radio is a technique referred to as Spectrum Fragmentation, essentially a method wherein high bandwidth waveforms, such as Soldier Radio Waveform and Wideband Networking Waveforms, are able to aggregate smaller chunks of available, unused spectrum into a larger allotment of bandwidth, the story said.

The Army plans to test the Spectrum Fragmentation technique in October at its next Network Integration Evaluation at White Sands Missile Range, N.M., the story said.
