摘要

现阶段NB-IoT网络已完成初步建设，整体覆盖较好，但局部覆盖空洞较多，室内疑难场景深度覆盖不足，干扰问题突出，重叠覆盖严重。目前NB-IoT行业应用成熟度低，行业应用属于起步阶段，各厂商终端规范不一，导致网络部署调通过程中存在较大问题。针对当前物联网的主要业务类型，依据不同业务特征来分析NB-IoT网络关联指标，根据测试数据与统计数据分析该类业务的覆盖性能，对井盖与灯杆类业务分别展开深度覆盖分析与重叠覆盖分析，对业务接入相对集中的业务模型给出优化解决方案。

Abstract

The preliminary construction of the NB-IoT network has been completed at this stage.The overall coverage is good

but there are more partial coverage holes

insufficient coverage of indoor difficult scenes

prominent interference problems and overlapping coverage.At present

the industry application of NB-IoT is low in maturity

and the application of the industry is in its infancy.Different terminal manufacturers have different specifications

which leads to major problems in the deployment process of network deployment.The NB-IoT network related indicators according to different business characteristics were analyzed

according to the main types of business of the internet of things.The coverage performance of such services was researched according to test data and statistical data.In-depth coverage analysis on the covers of manholes and poles was conducted.Overlapping coverage analysis gives an optimized solution to the business model with relatively concentrated service access.
