绵阳市科技城的5G室内覆盖方案分析

Analysis of 5G Indoor Coverage Scheme in MianYang Science and Technology City

因为5G信号的工作频段较高、衰减非常明显、穿透能力差、绕射能力差,室外5G信号覆盖室内空间尤为困难,因此,建设5G室内分布系统具有重大意义。文章首先介绍建设5G室内覆盖的意义、国内外5G应用的进展情况、国内5G频谱的分配情况,接着分析了5G室内覆盖面临的诸多挑战、与传统室分的差异,最后阐述了5G室内分布的诸多方案,并结合绵阳市科技城的建筑特点提出有源无源融合的5G室内覆盖方案建议。

Most of the application scenarios of 5G are indoor.At the same time,5G signal has high working frequency band,obvious attenuation,poor penetration ability and diffraction ability,so it is particularly difficult for outdoor 5G signal to cover the indoor space.Therefore,the construction of 5G indoor distribution system is of great significance.This paper first introduces the significance of building 5G indoor coverage,the progress of 5G application at home and abroad,and the distribution of 5G spectrum in China.Then it analyzes the challenges faced by 5G indoor coverage and the differences between 5G indoor coverage and traditional indoor coverage.Finally,it expounds many schemes of 5G indoor coverage,and puts forward some suggestions on 5G indoor coverage with active and passive integration based on the architectural characteristics of MianYang Science and technology city.
