摘　　要：介绍了一种物联网精准覆盖的评估技术,在现有网络上建设NB-IoT网络实现共站共天线基础上,构建NB-IoT网络精准覆盖评估平台。通过采集现网的后台覆盖指标、现网后台覆盖指标与现网实际覆盖指标差异规律、现网的实际覆盖指标与NB-IoT网络的实际覆盖指标差异规律3组数据,实现NB-IoT网络精准覆盖的评估,克服了NB网络全方位覆盖评估手段缺乏的壁垒。An accurate coverage evaluation technology of the Internet of things is introduced,which is based on the construction of NB-IoT network to realize co-site and co-antenna on the existing network,and builds a precise coverage evaluation platform for the NB-IoT. By collecting 3 groups of data:the background coverage index of the existing network,the difference rule between the background coverage index of the existing network and the actual coverage index of the existing network,and the difference rule between the actual coverage index of the existing network and the actual coverage index of the NB-IoT net-work,the accurate coverage evaluation of the NB-IoT network is realized,which overcomes the barrier of lacking comprehensive coverage assessment means of the NB network.
