Abstract

The use of Unmanned Aerial Vehicles (UAV) for civilian and commercial services has experienced a significant increase in the past couple of years. Emerging UAV enabled services, however, require extended beyond-visual-line-of-sight geographical range. One key regulatory requirement for these services is that the radio communication link must reliably cover a wide(er) area, when compared to the visual-line-of-sight range radio links currently used. Standardized cellular systems such as Long Term Evolution UMTS (LTE), are an obvious candidate to provide the radio communication link to UAVs. In this paper, we use empirical measurements in live rural LTE networks to assess the impact of uplink and downlink radio interference on the UAV radio connectivity performance. Further, we provide a baseline analysis on the potential of interference mitigation schemes, needed to provide a reliable radio connectivity to the UAVs.

基于航空无线电测量的无人机LTE连接干扰分析
在过去几年中,民用和商业服务中无人驾驶飞行器(UAV)的使用经历了显着增加。然而,新兴的无人机服务需要扩展超视距地理范围。这些服务的一个关键监管要求是,与目前使用的可视视距范围无线电链路相比,无线电通信链路必须可靠地覆盖更广的区域。标准化的蜂窝系统,如长期演进UMTS (LTE),是为无人机提供无线电通信链路的明显候选。在本文中,我们使用现场农村LTE网络的经验测量来评估上行和下行无线电干扰对无人机无线电连接性能的影响。此外,我们对为无人机提供可靠的无线电连接所需的干扰缓解方案的潜力进行了基线分析。
