On December 12, DARPA held the second preliminary event of the Spectrum Collaboration Challenge (SC2) – the world’s first collaborative machine-intelligence competition to overcome spectrum scarcity. Fifteen teams represented by members from across the academic, commercial and defense landscapes gathered at Johns Hopkins University Applied Physics Laboratory (APL) to pit their intelligent radio designs against each other in a head-to-head competition.
Over the past three years, DARPA’s Spectrum Collaboration Challenge (SC2) has relied on a custom-built virtual testbed called the Colosseum to host thousands of competitive matches and scrimmages, which will include the final match to determine the winner of the $2 million grand prize. Supporting SC2’s mission to reimagine new spectrum access strategies in which radio networks autonomously collaborate to determine how the RF spectrum should be used moment-to-moment required the development of a research environment capable of emulating communication signals at real-world scope and scale.
DARPA today announced the 10 teams that have qualified for the Championship Event of the Spectrum Collaboration Challenge (SC2) – a three-year contest to unlock the potential of the radio frequency (RF) spectrum using artificial intelligence (AI). The teams will head to Mobile World Congress Los Angeles on October 23, 2019, where their radio designs will go head to head during a live competition. The first, second, and third place winners will walk away with $2 million, $1 million, and $750,000 prizes, respectively.
DARPA today announced that GatorWings, a team of undergraduate students, Ph.D. candidates, and professors from the University of Florida are the winners of the Spectrum Collaboration Challenge (SC2) – a three-year competition to unlock the true potential of the radio frequency (RF) spectrum with artificial intelligence (AI). DARPA hosted the championship event at Mobile World Congress 2019 (MWC19) Los Angeles in front of a live audience. SC2’s final 10 competitors and their AI-enabled radios went head-to-head during six rounds of competitive play. GatorWings emerged victorious, taking home first place and the $2 million grand prize.
Today’s electromagnetic (EM) spectrum is a scarce resource that is becoming increasingly congested and contested as friendly, unfriendly, and neutral entities vie for available spectrum resources at any given time, location, and frequency. Within the Department of Defense (DoD), radio frequency (RF) systems, such as communications networks and radar, must operate within this congested environment and contend with mission-compromising interference from both self- and externally generated signals. A desire to support wideband EM spectrum operations also adds to the burden, as current approaches to mitigating wideband receiver interference are sub-optimal and force compromises around signal sensitivity, bandwidth usage, and system performance.
