NB-IoT性能浅析

Analysis on NB-IoT Performance

随着物联网应用的不断发展,针对低功耗广覆盖类LPWA应用设计的新型窄带蜂窝物联网NB-IoT技术,由于其低功耗、低成本、广覆盖、大连接的特点受到越来越多的关注,因此基于NB-IoT相关协议规范,通过传输机制分析,从用户速率、小区吞吐量等方面,分析了NB-IoT网络性能,为NB-IoT在智能抄表、智能家居、市政物联、物流追踪、智能穿戴、广域物联和工业物联等垂直行业中的进一步应用提供了参考。

With the continual development of the lnternet of Things （loT） applications, the novel Narrow Band （NB） cellular lot named NB-loT technology, which is designed for LPWA applications, attracts more and more attention due to its features of low power consumption, low cost, wide coverage and massive connection. Therefore, based on the corresponding protocol specification and transmission mechanism, the NB-IoT network performance was presented from aspects of user rate and cell throughput. This provides the useful reference to the further applications in the vertical industries such as intelligent meter reading, smart home, municipal IoT, logistics tracking, smart wear, wide area lot and industrial IoT.
