5G NR室分共享覆盖解决方案

5G网络工作频段分配越来越高,导致室外覆盖室内深度覆盖不足,传统室分存量DAS支持的频段最高到2.7 GHz,为兼顾性能合理利用建设成本,利旧原有网络中已经部署的室分天馈线及设备,分析了高频导致室内深度覆盖不足的特点,根据传统室分网络的现状,以5G业务价值判断需求为场景划分,结合网络中各需求场景室内分布系统的建设特点,利用多样化方案应对差异化需求,多种建设方案并存的理念,给出了面向5G频段室分系统共享覆盖的网络建设思路。

5G NR Indoor Sharing and Coverage Solution

The allocation of the working frequency for 5G networks gets higher,and leads to insuffi cient outdoor coverage and indoor coverage depth.Traditional indoor existing DAS supports up to 2.7 GHz frequency band.In order to jointly consider the performance and rational use of construction costs,the existing indoor distributed antennas and equipment in the old network are used to analyze the insuffi cient indoor coverage characteristics of high frequency.According to the current status of the traditional indoor distribution network,the scenarios are divided by the demands of 5G service value judgements.Combining the construction characteristics of the indoor distribution system for various demand scenarios in the network,the network construction ideas for shared coverage of 5G frequency indoor sub-systems are given using the concepts of differentiated service-oriented and multiple coexisting construction solutions.
