Lai Zhou, He Ma, Zhi Yang, Shidong Zhou, Wei Zhang
Abstract
Channel modeling plays an important role in unmanned aerial vehicle (UAV) communication system design and performance evaluation. In this article, we provide a brief review of the existing UAV channel modeling, emphasizing that UAV altitude is a significant factor in characterizing large-scale fading modeling. We then investigate the effect of UAV altitude on the system-level performance of various networks. Simulation results are provided to show the behavior of cellular-connected UAV networks with different channel models and conditions. In addition, we show that antenna design significantly affects system performance. (Table 1 summarizes the abbreviations used in the article).
