Narrowband Characteristics of Air-to-Ground Propagation for UAV Assisted Networks in Urban Environments By Means of Fast Ray-Launching Simulations

Unmanned Aerial Vehicles (UAV), also known as “drones”, are attracting increasing attention as enablers for many technical applications and services, and are emerging as a promising feature for constructing the next-generation mobile networks, with a special focus on the extension of coverage and capacity of mobile radio networks for 5G applications. In this paper we tackle this challenge and we aim at investigating the narrowband properties of the air-to-ground propagation channel by means of GPU accelerated ray launching simulations carried out in an urban environment for 5G communications.
