Simulation optimization scenario. In the simulation experiment of network element layout, the experimental scene was set as a “double L” region, with a total length of 24.1 m and a width of 17.8 m. According to the actual situation, select 3 m from the ground height to divide the 1 m × 1 m grid. A location near the wall was selected as the deployment of base station, a total of 102 locations for network deployment. The selected position of the terminal is 1.2 m away from the ground, and the 3D grid of 1 m × 1 m × 1 m is divided. Two hundred sixty-four terminals are located at the center of gravity of the grid. The yellow dot indicates the network element location to be installed and the green dot indicates the user terminal location
