无人机的许多用例需要超越视觉视距的通信。移动网络提供广域、高速和安全的无线连接，可以增强对无人机操作的控制和安全，并支持超越视觉视距的使用案例。在这篇文章中，我们分享了我们在低空小型无人机LTE连接方面的一些经验。我们首先确定了典型的机载连通性要求和特征，通过测量和射线跟踪结果突出了无人机和地面移动设备的不同传播条件，并给出了仿真结果，以阐明为无人机提供I.TE连通性的可行性。我们还提出了几个关于改善LTE连接性能的潜在增强的想法，并为未来的研究确定了富有成效的途径。
Many use cases of UAVs require beyond visual LOS communications. Mobile networks offer wide-area, high-speed, and secure wireless connectivity, which can enhance control and safety of UAV operations and enable beyond visual LOS use cases. In this article, we share some of our experience in LTE connectivity for low-altitude small UAVs. We first identify the typical airborne connectivity requirements and characteristics, highlight the different propagation conditions for UAVs and mobiles on the ground with measurement and ray tracing results, and present simulation results to shed light on the feasibility of providing I.TE connectivity for UAVs. We also present several ideas on potential enhancements for improving LTE connectivity performance and identify fruitful avenues for future research.
