基于蜂窝的窄带物联网(Narrow Band Internet of Things,NB-IoT)成为万物互联网络的一个重要分支。其构建于蜂窝网络,只消耗大约200KHz的带宽,可直接部署于GSM网络、UMTS网络或LTE网络,以降低部署成本、实现平滑升级。NB-IoT是一种可在全球范围内广泛应用的新兴技术,对长距离、低速率、低功耗、多终端的物联网应用具有较大优势。
The Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything. Constructed in a cellular network, it consumes only about 200 KHz bandwidth and can be directly deployed on a GSM network, a UMTS network or an LTE network to reduce the deployment cost and achieve a smooth upgrade. NB-IoT is an emerging technology that can be widely used worldwide. It has great advantages for long-distance, low-rate, low-power, multi-terminal IoT applications.
