DARPA has announced plans to hold a competition pitting electromagnetic spectrum receivers (think: TVs, wifi-enabled computers, radios). As the amount of mobile data traffic is growing at an exponentially rapid rate, DARPA believes we need to start refining the way we handle the crowded spectrum. The Spectrum Collaboration Challenge (SC2) will see research teams collaborating to create smart systems to share wavelengths using algorithms and artificial intelligence. Global mobile data traffic grew by 74 percent in 2015, and more than half a billion devices and connections were added to the overwhelmingly clogged spectrum, according to recent Cisco reports. Analysts expect that the monthly global mobile traffic rates will reach 30.6 exabytes by 2020 (rates are at 3.7 exabytes per month as of 2015).
