Cooperative Placement Method For 4G&5G Base Stations Based on Clustering and Improved Particle Swarm Optimization

5G base stations have been widely used. At the same time, 4G macro stations also have irreplaceable convenience. In order to better utilize the existing infrastructure and leverage the characteristics of the 5G base stations, this article proposes a cooperative placement method for 4G&5G base stations that utilizes an improved particle swarm optimization. To fit for the complex terrain of cities and maximize the use of different types of base stations, it also utilizes the DBSCAN algorithm to slice the map according to the density of buildings for clustering, and then places different types of base stations on different types of terrains. An improved particle swarm optimization algorithm is proposed to search for the best placement strategy on the complex terrain for maximizing the coverage of signal.
