摘要
本文通过聚焦高流量区域和高价值用户,建立覆盖、容量和结构综合评估模型,在现有4G网络的基础上,协同规划建设5G网络。基于当前4G网络存在的弱覆盖黑点和高负荷区域的情况,通过建设5G站点同步开通3D MIMO补充解决4G问题。结合现场环境,借助AAU的多通道垂直覆盖增益优势,有效解决楼宇室内深度覆盖不足的问题。同时利用FDD1800的上下行能力,精准规划FDD1800锚点站点,有效缓解高流量区域的容量压力,从而实现最大化提升4G网络质量和投资收益比的目标。
Through focusing on high traffic areas and high value users,establish a comprehensive evaluation model of coverage and capacity and structure.Based on the existing 4 G network,collaborative planning and construction of 5 G network.Based on the weak coverage black spots and high load areas in the current 4 G network,through building 5 G base station and open 3 D MIMO site,supplement and solve 4 G problems.Combined with the site environment and utilized the advantage of AAU’s multi-channel vertical coverage gain,solve the insufficient indoor depth coverage of buildings effectively.At the same time,using the uplink and downlink capabilities of FDD1800,accurate planning of FDD1800 anchor station,relieve the capacity pressure in high fl ow area effectively.So as to achieve the goal of maximizing the quality of 4 G network and maximizing the investment income ratio.
