Coverage Performance Analysis of Grid Distribution in Heterogeneous Network

With the growth of wireless communication services, large base stations will not only produce a lot of electromagnetic radiation, but also bring huge energy consumption, resulting in a large number of greenhouse gases. The fifth generation mobile communication will deploy the macro base stations and the micro base stations in multi-layer heterogeneous network to enhance the system network performance, reducing the negative impact of above-mentioned factors. According to the theory of cell communication, in this paper, by adding the micro base stations distributed in different grid modes in the surrounding area of the macro base station, the purpose is to maximize the total area covered by the base stations in the cell under the condition that the total power consumption of the base stations is not increased.
