Propagation Characteristics and Channel Capacity with Drone Height

To cope with the increase in communication traffic, the use of microwaves and millimeter-wave bands has been recently studied for outdoor use. However, the transmission enhancing the high received power has become a new challenge, because the path loss increases in the high frequency band. This study aims to reduce the propagation loss by relaying autonomous unmanned aerial vehicles (Drones). We propose a model based on the Drone height as a parameter and evaluate the channel capacity using the model to demonstrate the effectiveness of Drone relay stations.
