利用无人机改善城市和郊区环境中的LoRa信号覆盖

Improving LoRa Signal Coverage in Urban and Sub-Urban Environments with UAVs

摘要:

LoRa技术能够在城市和郊区环境中为物联网(IoT)设备实现低功耗的远距离通信。然而,由于城市和郊区环境中的地面结构,LoRa传输的链路距离可能会减少。在本文中,我们报告了建筑物内和建筑物间LoRa链路的信号强度测量,并提供了对影响信号质量的因素(如扩频因子和天线方向)的见解。随后,我们还提供了使用无人机(UAV)将LoRa发射机部署在不同高度时在城市和郊区环境中的测量结果。我们的研究结果表明,无人机部署高度是关键,以提高覆盖在郊区环境和天线的方向影响通信范围。

英文摘要:

LoRa technology enables long-range communication with low-power consumption for the Internet-of-Things (IoT) devices in the urban and suburban environment. However, due to terrestrial structures in urban and suburban environments, the link distance of LoRa transmissions can be reduced. In this paper, we report signal strength measurements for the in-building and inter-building LoRa links and provide insights on factors that affect signal quality such as the spreading factor and antenna orientation. Subsequently, we also provide measurement results in urban and suburban environments when the LoRa transmitter is deployed at different heights using an unmanned aerial vehicle (UAV). Our findings show that the UAV deployment height is critical for improving coverage in the suburban environment and antenna orientation affects the communication range.
