蜂窝通信以其无处不在的蜂窝覆盖使各种使用案例能够利用无人机进行远程空中检查、监视和监测。对于这些用例，命令和控制以及传感器数据(如视频)的交换需要可靠且低延迟的通信链路。在这篇文章中，我们介绍了在一个试验性的5G网络中进行的无人机通信测量活动的结果。测量场景涵盖(I)无人机和地面站之间链路的容量和质量，(Ii)无人机通信的健壮性和网络切片提供的隔离，以及(Iii)无人机和地面站之间远程飞行链路的稳定性。结果表明，蜂窝通信原则上满足长途飞行的视频和指挥控制数据的可靠性和延迟，即使蜂窝网络的性能针对地面设备进行了优化。网络分片在未来5G网络中的应用，在保护无人机关键指挥控制数据免受不必要的无线干扰方面具有巨大的潜力。
Cellular communications with its ubiquitous cellular coverage enable various use cases for long-distance aerial inspection, surveillance and monitoring with drones. For these use cases, the exchange of command & control and sensor data, such as video, require a reliable and low-latency communication link. In this paper, we present results of a measurement campaign of drone communications in an experimental 5G network. The measurement scenarios cover (i) the capacity and quality of the link between the drone and the ground station, (ii) the robustness of drone communications with the isolation provided by network slicing, and (iii) the stability of the link between drone and ground station for long-distance flights. The results indicate that cellular communications in principle meet the reliability and latency of video and command & control data for long-distance flights even when the performance of cellular network is optimized for terrestrial devices. The application of network slicing in future 5G networks has a great potential to protect the drone critical command & control data from undesired wireless interferers.
