摘要
为了支撑高速增长的物联网业务,运营商需快速部署网络。通过对NB-IoT在覆盖、功耗、连接数、成本等方面的优势进行比较,分析了NB-IoT的关键技术,并以中国电信NB-IoT网络部署为例,研究了NB-IoT总体架构、部署场景和部署频段,提出了NB-IoT的覆盖、容量、基站侧及核心网设计方案。
In order to support the rapid growth of the Internet of Things （loT） business, operators should quickly deploy networks. Advantages of NB-IoT in coverage, power consumption, connection and cost were compared and key techniques of NB-IoT were analyzed. According to the NB-IoT network deployment of China Telecom, the NB-loT overall architecture, deployment scenario and deployment frequency band were investigated. The design solution to NB-IoT coverage, capacity, cell and core networks was presented.
