N2 - In a high-density hotspot that occurs temporarily, the data rate per user is significantly reduced. In addition, if the base station stops working in the disaster area, it is necessary to provide wireless infrastructure promptly. To address in these situations, we focus on a UAV (Unmanned Aerial Vehicle) with wireless communication infrastructure to provide services. Moreover, for access links in UAV, it will be installed with mmWave interface to achieve high-speed throughput and line- of-sight environment could be guaranteed. However, under limited frequency bandwidth, when multiple UAVs are deployed, frequency interference will occur between UAVs, and the data rate will be deteriorated. To reduce the interference between neighboring UAVs, in this paper, we propose a combined method with placement and frequency division under the multiple UAVs environment. Hence, it turns out that the data rate is improved by proposal method under interference environment.
