Unmanned Aerial Vehicles, also known as drones, are emerging as enablers for supporting many applications and services, such as precision agriculture, search and rescue, or in the field of communications, for temporary network deployment and their coverage extension and security.

Giovanni Geraci, a researcher with the Department of Information and Communication Technologies at UPF, points out in a recent study: "On the one hand, it is important to protect the network when it is disturbed by a drone that has connected and generates interference. On the other, in the future, the same drones could assist in the prevention, detection, and recovery of attacks on 5G networks".

First, the use of UAVs to prevent possible attacks, still in its early stages of research, and, secondly, how to protect the network when disturbed by a drone, a much more realistic, as Geraci explains: "A drone could be the source of interference to users. This can happen if the drone is very high up and when its transmissions travel a long distance because there are no obstacles in the way, such as buildings".

Based on the premise that 5G terrestrial networks will never be 100% secure, the authors of this study also suggest using UAVs to improve 5G network security and beyond wireless access.

The study shows several areas in which the diversity and 3D mobility of UAVs can effectively improve the security of advanced wireless networks against eavesdropping, interference and 'spoofing', before they occur or for rapid detection and recovery.
