When vacationers buy a stake in a beachfront timeshare, they decide in advance who gets to use the property when. The National Institute of Standards and Technology (NIST) is helping the Federal Communications Commission (FCC) institute a similar plan for when commercial wireless providers and the U.S. Navy attempt to share a desirable 150-megahertz (MHz)-wide section of the radio frequency (RF) spectrum for communications.
In a new paper, NIST researchers demonstrate that deep learning algorithms—a form of artificial intelligence—are significantly better than a commonly used, less sophisticated method for detecting when offshore radars are operating. Improved radar detection would enable commercial users to know when they must yield the so-called 3.5 Gigahertz (3.5 GHz) Band.
