NB-IoT系统现状与发展

System Status and Development of NB-IoT

通过与现有长期演进(LTE)系统对比,认为窄带物联网(NB-IoT)在物理层、空口高层、接入网、核心网引入的各项优化特性能够很好地满足物联网低功耗、低成本、深度覆盖的典型需求。NB-IoT在标准体系统一、扩展能力上具有巨大优势,必将成为物联网技术及产业链发展、物联网应用在全球部署的有力推动者。

By comparing with the existing long term evolution(LTE)system,webelieve that the various optimization characteristics in physical layer,interface level,access network,core network of narrowband Internet of things(NB-IoT)can wellmeet the typical needs(low-power,low-cost,depth-coverage)of IoT.With theadvantages like unified standard system and easy to expand,NB-IOT will accelerateindustry chain progress and enable more business opportunities.
