In comparison to terrestrial communications or systems based on high-altitude networks, on-demand wireless systems using low-altitude UAVs can be deployed faster, can be reconfigured more easily, and will likely have better communication channels due to short-range line of sight links. The goal of this paper is to evaluate the use of UAVs in next-generation wireless networks, specifically as a flying base station. Ray-tracing simulations are used to simulate the coverage of a UAV-aided base station (UAV-BS) in a scenario with a fixed base station at the University of Glasgow, UK. The results imply that the UAV-BS will be of tremendous benefit to 5G network communication, such as capacity expansion in metropolitan regions, better coverage in rural areas, and network densification.","PeriodicalId":371560,"journal":{"name":"2022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134266976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
