Indoor Coverage Analysis for Unmanned Aerial Vehicle Base Stations

摘要

In this study, we investigate downlink indoor coverage performance of unmanned air vehicle (UAV) base stations. In order to obtain a reliable and practical simulation environment, we employ a probabilistic model for air-to-ground path loss whereas we handle the indoor losses in a deterministic manner. We assume that UAV base stations operate at the frequencies reserved for mission critical services. Therefore, we consider signal-to-noise ratio (SNR) for our coverage definition, and utilize four different SNR levels for our analysis. Throughout this paper, we observe the effect of UAV altitude on the radius of service area, and propose that our framework can be used to obtain the optimum altitude level for satisfying certain service criterion.
