Abstract

The invention provides an urban space 5G base station site selection optimization method considering a signal blocking effect. An artificial immune intelligent optimization model of a 5G communicationbase station is constructed, the number and the spatial layout of the communication base stations are optimized on the premise of considering the blocking effect of urban buildings on communication signals, and the number of the base stations and the maximization of the signal coverage range of the base stations are reasonably controlled. A CSA algorithm is adopted as an optimization decision algorithm, a spatial layout optimization technology with high calculation efficiency and high result feasibility is provided for basic characteristics and solving requirements of a spatial layout optimization problem of the 5G communication base station, and automatic and intelligent spatial layout site selection of the 5G communication base station is realized. The GIS technology is coupled with themulti-source geographic data and the space optimization decision method, so that the 5G signal service quality is effectively improved, the deployment and construction cost of the base station and the operation economic cost of the base station are reduced, and a decision basis and technical support are provided for planning and construction of the 5G communication base station in the future.

Description

technical field [0001] The invention belongs to the technical field of space deployment of communication base stations, and in particular relates to a site selection optimization method for 5G base stations in urban space considering the signal blocking effect. Background technique [0002] 5G communication technology, also known as the fifth generation mobile communication technology (5th generation mobile networks or 5th generation wireless systems, 5th-Generation, referred to as 5G or 5G technology), is the latest generation of cellular mobile communication technology. Compared with the existing 2G, 3G and 4G communication technologies, 5G communication technology has made a qualitative leap in terms of data transmission rate, reduced data delay, energy saving, and improved system capacity. Therefore, the development of 5G technology is of great significance to the development of Internet of Vehicles, autonomous driving, and artificial intelligence technology. In recent ...
