Unmanned aerial vehicles (UAV) have gained great popularity in recent years due to their decreasing cost and increasing functionality. In wireless communications, they are mainly used as aerial platforms to enable information delivery or power transfer. In this talk, applications of UAV in wireless communications are discussed. Firstly, aerial relaying using a group of UAVs will be studied. Two typical settings of using multiple UAVs in a multi-hop single link and in multiple dual-hop links will be optimized and compared to find the best solution for different scenarios. Secondly, UAV-enabled power transfer will be discussed. For sensors located in remote areas, UAVs will act as aerial hybrid access point to transfer power to the sensors after which the sensors use the transferred power to upload their sensing data. Finally, the use of UAV in maritime communications will be discussed. Currently maritime communications use either satellites or near-shore ground stations. Satellites are limited by latency while near-shore stations are limited by range. UAV provides an extra degree of freedom.
