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.
