Abstract

The invention discloses a base station average electromagnetic radiation prediction method. According to the method, the height of a base station transmitting antenna, the height of a prediction pointand the linear distance from the base station transmitting antenna to a prediction point are used to calculated the path loss of the base station signal; the maximum transmitting power of the base station and the transmitting antenna gain of the base station are combined to obtain the maximum electromagnetic radiation intensity of the base station at the prediction point, the duty ratio of a downlink signal of the base station is calculated through the downlink flow of the base station and the downlink rate of the base station, and finally the average electromagnetic radiation intensity of the base station at the prediction point is obtained in combination with the maximum electromagnetic radiation intensity of the base station and the duty ratio of the downlink signal of the base station. According to the method, the average electromagnetic radiation intensity of the base station can be quickly and accurately predicted, and the method has a great reference value for researching the electromagnetic radiation exposure condition of the base station and has certain social benefits.

Description

technical field [0001] The invention relates to a base station average electromagnetic radiation prediction method. Background technique [0002] With the continuous deepening of social informatization, wireless communication services have shown explosive growth, and a large number of new base stations have been put into use, posing potential threats to the environment and public health. At present, the prediction of the average electromagnetic radiation intensity of the base station is mainly calculated from the maximum electromagnetic radiation intensity of the base station measured by the spectrum analyzer and the signal duty cycle of the base station. However, the research on the theoretical calculation of the maximum electromagnetic radiation intensity of the base station and the duty cycle of the base station signal is still in the exploratory stage. [0003] Aiming at the deficiencies of the prior art, the present invention proposes a base station average electromagn...
