摘要

NB-IoT由于其功率谱密度、重传的技术特点

可实现较GSM系统20dB的覆盖增强能力

但是相应的终端芯片能力弱、单天线设置以及窄带宽设置

导致其抗干扰能力较差。本文主要阐述NB-IoT网络覆盖性能的评估及优化方法

针对现网发现的弱覆盖、重叠覆盖现象给出功率优化

异频组网以及干扰规避的解决方案。

Abstract

Due to its power spectral density and retransmission technology

NB-IoT can achieve 20 d B coverage enhancement over GSM systems. However

the weak terminal chip capabilities

single-antenna configuration

and narrow bandwidth settings result in poor anti-interference capability. This article mainly describes the evaluation and optimization methods of NB-IoT network coverage performance. For the weak coverage and overlapping coverage found on the existing network

power optimization

inter-frequency networking

and interference avoidance solutions are provided.
