Problems solved by technology

[0002] With the rapid development of communication technology, more and more frequency resources are used in mobile communication systems, and the number of base stations is also increasing. The resulting electromagnetic radiation from base stations gradually causes people to panic. Various buildings in urban areas can It has an impact on the propagation of radiation, but in the published literature and patents, the propagation of electromagnetic radiation of base stations is rarely connected with buildings, and the exposure level of electromagnetic radiation of base stations is effectively estimated

Abstract

The invention discloses a building-based base station electromagnetic radiation prediction method, the steps of which are as follows: firstly, the method proposes an attenuation model for base station radiation signals propagating through buildings, and obtains the attenuation of base station signals after passing through buildings with a height of h after calculation power k(h); then count the value of the building height h between the base station and the point to be measured, and determine the number of buildings, calculate the total attenuation power P(h), and then combine the base station electromagnetic radiation intensity calculation formula S, finally predicting and obtaining the base station electromagnetic radiation value of the point to be measured at a distance of r from the base station, the present invention calculates the attenuation power of the base station radiation signal propagating through the building according to the height of the building, and accurately predicts the electromagnetic radiation intensity of the base station at the point to be measured.

Description

technical field [0001] The invention relates to a building-based base station electromagnetic radiation prediction method. Background technique [0002] With the rapid development of communication technology, more and more frequency resources are used in mobile communication systems, and the number of base stations is also increasing. The resulting electromagnetic radiation from base stations gradually causes people to panic. Various buildings in urban areas can It has an impact on the propagation of radiation, but in the published literature and patents, it is rare to link the propagation of electromagnetic radiation of base stations with buildings, and to effectively estimate the exposure level of electromagnetic radiation of base stations. [0003] Aiming at the deficiencies in the existing technology, this patent proposes a building-based base station electromagnetic radiation prediction method. The method first proposes the attenuation model of the base station radiatio...
