低功率、大连接广域物联网接入技术及部署策略

The Research of Low Power Wide Area loT Technology and Deployment Strategy

物联网蓝海市场逐步凸显,万物互联需求被提出,各类新的物联网接入技术纷纷涌现。随着LoRa、Sigfox等基于非授权频谱的接入技术的成熟,运营商提出了基于蜂窝的NB-loT、eMTC等低功率、大连接广域物联网接入技术。文章首先介绍物联网的整体架构以及各组成部分的功能;其次,从标准演进、产业链成熟度等角度对各类物联网接入技术进行分析;最后,讨论运营商低功率、大连接广域物联网的业务发展和网络部署策略。

IoT blue ocean market is gradually revealing. The demand of Internet of Everything has been raised along with kinds of new short range IoT access technology. The rapid development of LoRa, Sigfox technologies which are based on unlicensed spectrum has promoted the mobile operators to propose the cellular IoT access technology such as Narrow Band IoT （NB-IoT） and enhanced Machine Type Communication （eMTC） which are based on the licensed spectrum. In this paper, we firstly introduce the end-to-end architecture of IoT network and function of each component. Secondly, we analyze all IoT access technologies from the aspect of the standard evolution, industry chain maturity. Finally, the strategies of LPWA network deployment and business development are discussed.
