AT&T deploys drones for cell tower inspections, network expansion

AT&T is now using drones to conduct aerial inspections of its cellular towers and foresees them as a way to beef up its wireless LTE network.
Down the road, the carrier said it might use a drone as a Flying Cell on Wings (COW) to enhance LTE coverage at a large concert or sporting event where thousands of fans can clog the network. Or a drone could be used in rapid disaster response, offering wireless coverage when a vehicle is unable to drive to an area hit by a storm or other catastrophe.
