Abstract

In recent years, Unmanned Aerial Vehicles (UAVs)
have been used extensively in military and civilian fields, making
the research on cellular-connected UAVs a popular topic for
Fifth Generation (5G) and beyond communications. In order
to support the increasing amount of applications, it is essential
to evaluate the performance of UAV communications. In this
work, the end-to-end delay, packet success rate, and throughput
of Air-to-Ground (A2G) communications are evaluated based
on a realistic channel model obtained from measurements. The
measurement campaign, conducted in a suburban environment,
includes both Line-of-Sight (LoS) and Obstructed Line-of-Sight
(OLoS) scenarios. From the results, it can be seen that architectural
elements close to the flight route can severely decrease the
communications performance even when the visibility between
the Base Station (BS) and the UAV is permanently ensured.
Moreover, we have shown that the Quality of Service (QoS)
requirements for critical communications proposed by 3rd Generation
Partnership Project (3GPP) can be fulfilled by establishing
a threshold on the received Signal to Interference and Noise
Ratio (SINR). This way, the SINR can be used as a condensed
performance metric for the design of safe flight routes for critical
communications for UAVs.
