Abstract:

Unmanned aerial vehicle(UAV) equipped with communication equipment,as air base stations,can enhance the coverage and capacity of the communication network effectively,due to the characteristics of flexible and rapid deployment.Compared with the traditional mobile communication network,not only the deployment density,but also the flight height of UAV has an influence on the performance of UAV communication networks.The influence of the parameters of UAV communication networks on capacity and coverage was studied.Through the system level simulation,with the increase of UAV deployment density,the capacity and coverage of the UAV communication network have been significantly improved.With the increase of UAV flying height,the capacity of the network shows a trend of increasing firstly and then decreasing.

Key words: UAV network, coverage, network capacity
