Cell services are at some of their worst behaviors at music concerts, baseball games and other similar large public gatherings. AT&T thinks it might have a solution for it. In a blog post today, the carrier company announced the idea of building cell extensions into drones and flying them in to handle the large dense traffic demands. From a report:AT&T has dubbed the drones "Flying COWs" -- the COW stands for âoeCell on Wings.â 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.
