摘要(Abstract)：
基于LoRa的低功耗广域网技术有望成为未来物联网的主干支撑技术之一。为了给工作在不同应用环境中的LoRa无线传感器网络节点间的传输提供简单有效、易于使用、成本低廉的测试手段,提出一种基于智能手机的LoRa无线传输效能测试系统。该系统由智能手机及与之配套的低成本测试节点组成。对组成系统的智能手机端App及测试节点设计进行讨论,系统完成后利用其在智能楼宇与智慧农业的应用场景下进行测试。测试结果表明,LoRa无线传输在不同的应用环境中会受到外界因素的干扰,通过本系统可方便、有效、快捷地获得分散在较长时间周期内的数据,为基于LoRa的无线传感器网络在设计、安装与维护中提供以数据传输效果为表征的参考测试数据。
