DARPA thinks artificial intelligence could wring out bandwidth from the radio spectrum

One of the huge drawbacks of modern technology is that it fills the air around us with radio signals. From your kitchen radio to your LTE-enabled smartphone, all of these devices use radio waves to communicate. Unfortunately, there is only a certain amount of radio frequencies that can be used. DARPA (Defense Advanced Research Projects Agency) is looking for a way around this problem, and wants teams to develop an artificially intelligent system that will control what devices use what radio waves and when. Basically, instead of forcing devices to make use of narrow frequency bands when the spectrum gets congested, DARPA wants devices to negotiate sharing frequencies when they need them.
