C4ISRDARPA puts its money on spectrum sharing By George Leopold Jul 22, 2016 As the Pentagon seeks to cram more electronic gear and wireless devices into a shrinking amount of radio spectrum, its research arm announced guidelines this week for yet another technology competition designed to find new ways to share and ensure access to the airwaves. The Defense Advanced Research Projects Agency announced a Spectrum Collaboration Challenge in March designed to leverage emerging machine-learning tools. The goal is to develop smart systems that can adapt in real time to congested spectrum as a way to boost the overall flow of radio frequency signals. DARPA this week formally announced the three-year competition would begin in 2017, with the finalists competing in 2019 for a $2 million grand prize. Competitors operating software-defined radios…
