The company is building LTE-enabled drones for a range of uses cases. They could be deployed if networks go down in the event of a disaster, to assist in scenarios like forest fires, or for large events like concerts.
On Tuesday and Wednesday, the company conducted its first test-flights drones equipped with LTE radios. AT&T says it is the first wireless company to test this technology.
