Channel analysis in a realistic path loss model for drones support in wireless communications

Abstract

In the near future, drones are expected to increase their interest and be adopted for an ever-growing number of tasks in different fields. This creates multiple challenges in terms of system/navigation, requiring significant integration efforts, multiple testbeds and deployment results, and novel protocols. One of the main aspects under studying by scientific community regards the possibility of using drones as relays in the sky. This brings to a series of issues around the channel link and the drones behavior in wireless communications both for sending commands or data in the bidirectional channel. In literature, many works are dedicated to the channel in drone environment and to the path condition for the specific considered scenario. In this work, we present an analysis of drone channel in a realistic path loss model for wireless communications, considering geometry parameters, the coverage radius and drones height on order to provide the correct connectivity to users.
