WASHINGTON — The White House on Monday announced a strategy to potentially expand the availability of radio spectrum needed for cellphones, satellites, navigation, space travel and other emerging technologies.

The increasingly digitized and mobile economy has put pressure on the available range of frequencies used for wireless communication. The spectrum is also vital for national security and responding to disasters.

The National Telecommunications Information Administration will perform a two-year study on how to possibly repurpose 2,786 megahertz of spectrum, which could be used for wireless broadband, drones and satellites.
