This chapter discussed the use of UAVs in wireless communication network, specifically, the use of UAVs as aerial BSs and as aerial UE in cellular‐assisted systems. In both cases, the accurate channel model of the AG and AA propagation is paramount, which must take into account the environmental conditions, wireless channel impairments, and the UAV mobility to characterize the performance of UAV‐based communication network. Some channel modeling efforts have been studied in this chapter. In addition, key challenges, such as optimal deployment of UAVs, optimization of trajectory path, resource management, and energy efficiency, have also been highlighted.
