Unmanned aerial vehicles (UAVs) are being used in many applications,
such as surveillance and product delivery. Currently, many
UAVs are controlled by WiFi or proprietary radio technologies.
However, it is envisioned that 5G and beyond 5G (B5G) networks
can connect the UAVs and increase the overall security due to improved
control by operators and governments. Soon, UAVs will
also be used as mobile radio base stations to extend reach or improve
the network capacity. All this motivates intense research on
5G technologies for supporting UAV-based applications. However,
there are currently few simulation tools for testing and investigating
telecommunication systems that involve UAV solutions. For
instance, modern 5G networks use multiple antennas that enable
beamforming. A realistic simulation, in this case, requires not only
support for beamforming but also for realistic UAV trajectories,
which impact the communication channel evolution over time. To
evaluate scenarios with connected UAVs, this paper presents a tool
that simulates flights in a virtual environment, gathers information
about the channels among UAVs and the mobile network, and
calculates performance indicators regarding the communication
system.
