Application of LoRaWAN Technology in Metropolitan Narrowband Wireless Internet of Things

为了避免城域窄带无线物联网接入误差以及低速率等问题对应用效果的影响,研究LoRaWAN技术在城域窄带无线物联网的应用。明确LoRaWAN线性调频进行物联网执行的实际目标,并加强城域窄带无线冗余比特值的控制。在ADR机制下设计终端覆盖应用模型,采用LoRaWAN多场景循环切换,实现物联网的应用。实验分析结果表明,在不同的城域窄带无线应用范围下,对比于未应用LoRaWAN技术的物联网测试组,应用LoRaWAN技术的物联网测试组覆盖率均在90%以上,应用范围更加广泛,应用效果也更佳,具有潜在的应用意义。

In order to avoid the impact of metro narrowband wireless Internet of things access error and low rate on the application effect,the application of LoRaWAN technology in metro narrowband wireless Internet of things is studied.Clarify the actual goal of LoRaWAN linear frequency modulation for the implementation of the Internet of things,and strengthen the control of metropolitan narrowband wireless redundant bit value.The terminal coverage application model is designed under ADR mechanism,and LoRaWAN multi scene cyclic switching is adopted to realize the application of Internet of things.The experimental analysis results show that under different metropolitan narrowband wireless application ranges,compared with the IOT test group without LoRaWAN technology,the coverage of the IOT test group with LoRaWAN technology is more than 90%,the application range is wider,the application effect is better,and has potential application significance.
