[0002] As mobile communication technology brings infinite communication convenience to people, personal mobile smart devices in cities have become a necessity of life, and the electromagnetic radiation brought by base stations has caused more and more people to panic. However, in the published literature and patents , usually only considers the impact of a single or single-layer base station, and does not consider the radiation value of multi-layer base stations exposed to the urban area under the heterogeneous cellular network. There is no method to consider the heterogeneous cellular network in the urban area. Base station cluster distribution, effectively predicting the total electromagnetic radiation exposure level of each base station in the urban area

The invention discloses a method for predicting electromagnetic radiation of base stations in a double-layer cellular network. According to the specific value of the number of macro base stations under the conditions, the distribution coordinates of the macro base stations are obtained in MATLAB according to the uniform distribution algorithm, and the Voronoi diagram is made in MATLAB with the coordinates of the macro base stations as the base point by the dual generation method. According to the intersection of the edges of the Voronoi diagram (node) to get the weak coverage point k and the corresponding coordinates (M j ,N j ), obtain the probability distribution P(m) of the number of micro base stations in the area through the number k of weak coverage points, and further obtain the specific value of the number of micro base stations under the conditions, and then obtain in MATLAB according to the uniform distribution algorithm in the circle The distribution coordinates of micro base stations are finally predicted to obtain the total electromagnetic radiation value of macro base stations and micro base stations in the urban area.
Description
technical field [0001] The invention relates to a method for predicting electromagnetic radiation of a base station in a double-layer cellular network. Background technique [0002] With the infinite communication convenience brought by mobile communication technology to people, personal mobile smart devices in cities have become a necessity of life, and the electromagnetic radiation brought by base stations has caused more and more people's panic. , usually only considers the impact of a single or single-layer base station, and does not consider the radiation exposure of multi-layer base stations in urban areas under heterogeneous cellular networks. The cluster distribution of base stations can effectively estimate the total electromagnetic radiation exposure level of each base station on each floor in the urban area. [0003] In view of the deficiencies of the prior art, the present invention proposes a method for predicting electromagnetic radiation of a base station ori...
