So you’re at a Beyoncé concert, but can’t Snapchat a video. You want to text your friends your location at a baseball game, but your phone has no signal. Packed venues like these are notorious for poor cellphone reception. Well, AT&T says it has a solution: drones.

AT&T Inc. T, -1.19% says it is exploring providing LTE wireless coverage at crowded venues, like concerts and baseball games, by using a drone that is tethered to the ground but hovering in the air nearby.

AT&T has dubbed the drones “Flying COWs” -- the COW stands for “Cell on Wings.” The drones would boost LTE coverage to areas in need of it during occasional large events. They would be tethered to the ground to prevent them from going rogue and flying away.

The trial project is part of AT&T’s just-launched national drone program, which will focus on how AT&T and its customers can benefit from drones.

The program director, Art Pregler, said they wouldn’t have to fly too high, perhaps just under the roofline of stadiums or buildings.

AT&T also envisions that Flying COWs could provide boosted coverage in disaster response situations, particularly when vehicles aren’t otherwise able to drive into the affected areas.

AT&T currently deploys portable mobile cellular sites on the ground to provide temporary coverage in the form of trucks with an antenna tower mounted to it. AT&T deployed nine of those during the Super Bowl in the San Francisco Bay Area earlier this year.

During the 2011 Super Bowl, 177 gigabytes were used on AT&T’s in-stadium network. That number increased in 2016 to 5.2 terabytes, which is equivalent to 15 million social media posts with photos.

AT&T already uses drones to perform aerial inspections of cell towers -- a dangerous and slow task that humans used to perform. Drones are even able to access parts of cell towers that humans cannot.

AT&T said it uses a range of drones from different manufacturers, including DJI’s Inspire drone, which can cost less than $2,000.

Since the Federal Aviation Administration legalized commercial drone in June, more businesses are promoting their research on how drones could benefit their operations. Exxon Mobil XOM, -3.02% this week announced it was using drones to search for whales, while other businesses are approaching consumers with family-oriented drone racing entertainment venues akin to a go-kart racecourse.

Goldman Sachs estimates the global market for commercial drones will be worth $21 billion over the next five years, according to a March 2016 report.
