摘要
随着全球物联网(IoT)产业技术的进一步发展,对于低带宽、低功耗、远距离、大量数据连接的物联网应用需求愈发增加,其中低功耗广域网络(LPWAN)技术正是为满足此需求应运而生的远距离无线通信技术。LPWAN技术可分为两类:一类是工作于未授权频谱的LoRa、SigFox等技术,另一类是工作于授权频谱的NB-IoT等技术。本文分析了现有的国内外LPWAN技术的优劣势以及芯片开发情况,并对未来LPWAN的发展提出了思考和建议。
With the further development of the global IoT industry technology,the demand for low-bandwidth,low-power,long-distance,and massively connected IoT applications is increasing.Low-power wide-area network(LPWAN)technology is just to meet this demand.The birth of long-distance wireless communication technology.LPWAN can be divided into two categories:one is LoRa,SigFox and other technologies that work on unlicensed spectrum,and the other is NB-IoT and other technologies that work on licensed spectrum.This article analyzes the advantages and disadvantages of the existing domestic and foreign LPWAN technologies and chip development,and puts forward thoughts and suggestions on the development of LPWAN in the future.
