Electronic enthusiasts eight o'clock: According to foreign media reports, the US wireless operator AT&T recently conducted the first test flight of the "Cell-On-Wings" emergency LTE network drone in Atlanta. The company hopes to temporarily improve the wireless LTE coverage of its network load zone through drones. AT&T hopes to use the technology in the future to restore communications in areas experiencing natural disasters and to provide additional protection for popular events, such as concerts or sports.

In addition to improving the quality of the network under large public events, the technology will be able to be used in disaster sites in the future. Many times, when a major disaster occurs, people may not even be able to make calls, so it is especially important to keep the telephone network open at this time.

A single flight base station can provide network coverage for a radius of 40 square miles, with approximately 100 American football fields. In addition, they are still trying to use drones to detect nearby base stations and use them to quickly improve service quality. The drone can also be used with the ground (vehicle) base station Cell on Light Truck (COLT) to provide uninterrupted work to some extent.
