With the development of the 5G network, many emerging technologies which highly depend on the performance of communication have appeared and their performance is improved significantly. UAVs applications are becoming popular in many fields. They create new opportunities and lifestyles but also new challenges. UAVs assist the communication and transmit throughput as well as consuming the energy. In this paper, we study the energy efficiency of uav given certain trajectories. We derive two models on the communication scenarios dominated by LOS and NLOS communications respectively. They share the same propulsion energy consumption model where is based on UAV’s mass and velocity. For the NLOS communication scenario, we investigate how the altitude impacts the throughput. For the case of the LOS scenario, we suppose UAVs flying in a circular trajectory and study the impact of the radius. Because of the obstructions like terrains, altitude is investigated in the NLOS communication. Meanwhile, the coverage area of all users is considered in both scenarios. We deliver the experiments in investigating flight radius and altitude respectively. The results meet our expectation that there will be an optimal radius and altitude to have the optimal energy efficiency. Meanwhile, we have discussed some future directions which can be extended from our works.
