Abstract
Unmanned aerial vehicles (UAV) deployment and emerging air-to-ground wireless services have been a topic of great interest in the last few years. The main virtue of UAV networks is that they provide on demand connectivity. However, the design of such networks is intrinsically dependent on the air-to-ground propagation conditions. In order to construct a reliable air-to-ground channel model that takes into account the nature of the surrounding environment, we propose to exploit the information provided by building footprints. The obtained results are compared with existing statistical air-to-ground channel models. It is shown that both the the path loss exponent and the variance of the shadow fading are dependent on the distance on the ground between the UAV and the user and the drone’s altitude. The proposed channel modeling method is then used to estimate the coverage probability over the studied area.
