The role of machine learning in autonomous spectrum sharing

Launched in 2016, SC2's goal is to create a collaborative machine-learning competition to address radio frequency (RF) spectrum challenges. DARPA experts created SC2 to help users of the existing radio spectrum overcome the problem of clogged spectrum. Demand for radio spectrum has grown steadily over the past century, and in the past several years has increased at a rate of 50 per-cent per year. SC2 wants to move away from traditional ways of communicating via one frequency. As Paul Tilghman explained during his keynote speech at NIWeek, one of the biggest obstacles in spectrum management is that "frequency isolation completely dominates our spectrum landscape."
