A flying COW ("cellular on wings") is providing a 5G network in areas with limited infrastructure and after natural disasters. The technology convergence of drones and 5G is an interesting test case for rapid, flexible network deployments that provide a useful stopgap in critical areas. "We had intermittent, weak LTE signal at the flight location before we launched the 5G Flying COW," said Ethan Hunt, Unmanned Aircraft Systems (UAS) Principal Program Manager, AT&T, about a recent test. "We flew the drone up to about 300 feet, turned on the signal and it began transmitting strong 5G coverage to approximately 10...
