Design of an Emergency Communications UAV System Compatible for All Chinese Telecom Operators and Its Ground Coverage Strategy
摘要
Abstract
To support emergency missions concerning communication resume,the advantages of using an unmanned aerial vehicle(UAV)airborne base station,accompanied by large fixed-wing UAVs,have been demonstrated.The authors discuss the limitations of current large fixed-wing UAVs that carry a single base station for one telecommunications operator,resulting in discrimination among basic telecommunications enterprise users,limited network capacity,inadequate base station redundancy,and low reliability.The need to investigate and create emergency communication UAVs to support all telecommunications operators is emphasized.Furthermore,crucial technologies necessary to achieve the aforementioned objective are investigated.It is shown from signal coverage simulation,flight test examination and real-world inspection that UAVs for the whole network emergency communications can simultaneously provide China Telecom,China Mobile,China Unicom and other public telecommunication network signals,covering the area of not less than 50 square kilometres,without significant signal fluctuations,the level is not less than-110 dBm,and can provide a stable and reliable emergency communication guarantee for the whole network of users in the communication blocking area.关键词
