摘　　要：物联网应用中,低速率业务占比超过了50%。以NB-IoT和LTE-eMTC为代表的低功耗广域蜂窝技术在低功耗、广覆盖业务中扮演着重要角色。对物联网通信技术的分类和演进路线进行了阐述,介绍了NB-IoT和LTE-eMTC 2种典型的蜂窝通信技术的标准进展,最后给出了中国联通物联网的演进策略和蜂窝物联网的部署方案。More than half of the loT applications are low data-rate business. Low power wide area（LPWA） cellular technologies, such as NB-IoT and LTE-eMTC, play an important role in low-power and wide-coverage application. It firstly describes the classifica- tion and the evolution route of loT communication technology, then introduces the standardization progress of NB-IoT and LTE-eMTC, which are two typical cellular communication technologies. Finally, it analyzes the loT evolution strategy of China Unicorn and presents the deployment schemes of cellular loT.
