Problems solved by technology

[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, but the published literature and patents , usually only consider the radiation value exposed by a single base station to the area. There is no method to effectively estimate the total electromagnetic radiation exposure level of each base station in the area based on the distribution of base stations in the urban area.

Embodiment Construction

[0033] The implementation object of the present invention is the base stations of the three major operators' 2G / 3G / 4G network standards, and the working frequency bands are: Mobile 2G (890MHz~909MHz), 3G (2010MHz~2025MHz), 4G (2575MHz~2635MHz), China Unicom 2G ( 954MHz ~ 960MHz), 3G (2130MHz ~ 2145MHz), 4G (1955MHz ~ 1980MHz), Telecom 2G (825MHz ~ 840MHz), 3G (870MHz ~ 885MHz), 4G (1850MHz ~ 1880MHz), the locations are urban commercial intensive areas and ordinary In the urban area, the test area is 350m×350m, and the measuring equipment is AT6030D spectrum analyzer (frequency range 9kHz-3GHz) produced by Antaixin Company and PCD82_50 omnidirectional antenna (frequency range 80MHz-3GHz). The antenna factor It is 30dB / m, and the cable loss is 3dB.

Abstract

The invention discloses an urban area base station electromagnetic radiation prediction method. The method comprises the following steps of dividing an urban area into the two types of an intensive commercial area and an ordinary urban area; calculating the probability distribution P(n) of the number of base stations in the area through the total value of mobile phone traffic in the area to be tested; further calculating the specific value of the number of the base stations under a condition; and obtaining the distribution coordinates of the base stations according to an uniform distributed point algorithm, and finally predicting and acquiring the total electromagnetic radiation value of each base station in the area. According to a mobile phone traffic usage value in the area, the numberof the base stations is analyzed and acquired, and then base station distribution point analysis is performed, and the electromagnetic radiation intensity of the base stations in the area is accurately predicted.

Description

technical field [0001] The invention relates to a method for predicting electromagnetic radiation of a base station in an urban area. Background technique [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 consider the radiation exposure of a single base station to the area, and there is no method to effectively estimate the total electromagnetic radiation exposure level of each base station in the area based on the distribution of base stations in the urban area. [0003] In view of the deficiencies in the existing technology, this patent proposes a method for predicting electromagnetic radiation of base stations in urban areas. This method divides urban areas into two types: dense commercial ar...
