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. At the event's conclusion, six of the eight top-scoring teams walked away with $750,000 each in prize money. While not all competitors received interim prizes, all 15 teams have an opportunity to move on to the next stage and compete in the 2019 Spectrum Collaboration Challenge grand finale, which will be held in conjunction with MWC19 Los Angeles, in partnership with CTIA, on October 23, 2019.
The six prize-winning teams from the second preliminary event are:
"During the second preliminary event we witnessed a technological shift," said Paul Tilghman, the DARPA program manager leading SC2. "For the first time, we saw autonomous collaboration outperform the status quo for spectrum management."
Starting in early December, each team's radio participated in 105 matches against competitors in the Colosseum, a massive RF testbed that was developed specifically for SC2. The matches were held in a round-robin fashion where each radio network – working in groups of threes, fours or fives – had multiple opportunities to compete against every other radio design in the competition. Roughly 400 matches were held in total to determine the final team rankings and the prize recipients.
During the PE2 matches, teams were put through six different RF scenarios designed to mimic the challenges that collaborative, autonomous radios will face in the real world. These scenarios challenged the radios to collaboratively mitigate interfering with an incumbent radio system, sense and adapt to the spectrum demands of high-traffic environments, handle the data demands of the connected soldier of the future, and beyond. Each scenario was designed to pressure test various elements of the teams' approaches and, in particular, their ability to successfully collaborate with the other radios operating within the same environment.
“The six different scenarios were closely aligned to actual situations that our defense and commercial systems face in the field. The Wildfire scenario, for example, replicates the complex communications environment that surrounds an emergency response situation, while the Alleys of Austin scenario was designed to mimic what's needed to help dismounted soldiers navigate and communicate as they sweep through an urban environment. This real-world relevance was critical for us as we want to ensure these technologies can continue to develop after the event and can transition to commercial and/or military applications,” said Tilghman.
The sixth scenario of the competition was used to determine the six prize winning teams. This scenario explored the essential question of the SC2 competition: can the top teams' collaborative SC2 radios outperform the status quo of static allocation? Each of the six teams that received awards at PE2 demonstrated that their radio was capable of carrying more wireless applications without the aid of a handcrafted spectrum plan, while simultaneously ensuring four other radio networks operating in the same area had improved performance. In short, each of these six radio networks demonstrated the autonomous future of the spectrum.
To aid with decision making, teams applied AI and machine learning technologies in various ways. Some leveraged the current generation of AI technologies like deep learning, while others used more conventional optimization approaches. There were also a few teams that used first wave, rule-based AI technologies.
“We're very encouraged by the results we saw at PE2. The teams' radios faced new and unexpected scenarios but were still able to demonstrate smart, collaborative decision making. PE2 showed us that AI and machine learning's application to wireless spectrum management creates a very real opportunity to rethink our current century-old approach,” said Tilghman.
The competition now enters its third year and moves closer to the finale, which will be held at one of the country's largest annual technology and telecommunications shows – MWC19 Los Angeles. More than 22,000 attendees from the broad mobile ecosystem and adjacent industry sectors will convene at this three-day event to discuss the current opportunities and future trends shaping the industry. The SC2 championship event will be held on the keynote stage of MWC19 Los Angeles on October 23, 2019.
At the conclusion of SC2's finale, three teams will be awarded $2 million, $1 million and $750,000, respectively, for first, second and third place. The real prize, however, will be the promise of a more efficient wireless paradigm in which radio networks autonomously collaborate to determine how the spectrum should be used moment-to-moment, helping to usher in an era of spectrum abundance.

With defense budgets expected to be coming in flat under even best-case scenarios, the time for tough decisions might be coming. By PAUL MCLEARY WASHINGTON: The Pentagon may slash older weapons programs to buy new ones in coming years if the federal government's COVID-19 response takes a big bite out of budgets, Defense Secretary Mark Esper said today. Before the global pandemic slammed American society and ground the economy to a halt, Pentagon leaders were already looking at flat defense budgets and were casting about for fat to trim. But the trillions Congress and the Trump administration has pumped into the economy, which falls on top of an already exploding budget deficit, could make predictions of flat budgets look optimistic. Esper told reporters at the Pentagon he would target older programs: “We need to move away from the legacy, and we need to invest those dollars in the future. And we have a lot of legacy programs out there right now — I could pick dozens out from all branches of the services” that could be cut or curtailed. As Army Secretary in 2018, Esper's “Night Courts” saved the service some $33 billion through scrapping oler programs with an eye to pumping cash into new weapons programs. The Navy is undergoing a review that aims to shave $40 billion in the coming years, and the Marine Corps is aggressively getting rid of troops, tanks, helicopters, and — possibly — trimming the F-35 to make room for modernization investments. In particular, the massive modernization of the nuclear delivery systems will not be touched. Esper said “we're not going to risk the strategic deterrent we need to modernize,” if budgets trend downward, but acknowledged that cutting old weapons systems before their replacements were ready “would mean probably accepting some near term risk, but I think [modernizing is] important given the trajectory that China is on, and we know where Russia may be going in the coming year.” Earlier this week, Esper said he was concerned that exploding budget deficits would put an end to the dream of 3% to 5% yearly defense budget growth, which he had targeted for Pentagon modernization. “There is a concern there that that may lead to smaller defense budgets in the future at the critical time we need to continue making this adjustment, where we look at China, then Russia, as our long-term strategic competitors,” he said at the Brookings Institute. Some lawmakers are bracing for the coming cuts. “I am extremely concerned about that,” House Armed Services Committee member Rep. Mike Gallagher told me recently. “I think it is going to require defense hawks, like myself, to make not only more energetic arguments, but new and creative geopolitical arguments,” to advocate for spending on modernization programs. “If you assume downward pressure on the defense budget, it means that DoD will need to get the most out of every dollar spent.” Those arguments will be critically important for the services as they pitch their latest modernization efforts. “I think the budget comes down sooner rather than later,” Mackenzie Eaglen, resident fellow at the American Enterprise Institute, said during a recent webinar Adding fuel to that view was Todd Harrison, DoD budget expert at the Center for Strategic and International Security, who added, “what has historically happened is, when Congress's fiscal conservatives come out and get serious about reducing the debt, reducing spending on defense is almost always part of what they come up with for a solution,” he said. “So, we could be looking at a deficit-driven defense drawdown coming.” https://breakingdefense.com/2020/05/old-weapons-under-fire-as-covid-debt-rises/
