Abstract

The invention discloses a base station electromagnetic radiation prediction method based on regional user distribution. The method considers the influence of the user distribution in the predicted area on the electromagnetic radiation of the base station, and calculates the difference in the predicted area by establishing the location transition matrix of users in the predicted area. The average number of users at the location, and then according to the probability distribution of the number of active users, the actual transmit power of the base stations at different locations is calculated, and then the electromagnetic radiation intensity at different locations in the forecast area is obtained. The invention can quickly and accurately predict and evaluate the electromagnetic radiation intensity of the base station at different locations in the forecast area, has great reference value for the research on the electromagnetic radiation exposure of the base station, and has certain social benefits.

Description

technical field [0001] The invention relates to a base station electromagnetic radiation prediction method based on regional user distribution. 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, providing great convenience for communication between people and the exchange of social information. At the same time, communication base stations use electromagnetic waves as information transmission carriers, causing serious electromagnetic radiation problems. Traditional base station electromagnetic radiation research is usually analyzed in combination with the maximum transmit power of the base station and the base station signal duty cycle, but in fact, the electromagnetic radiation intensity of the base station is related to the distribution of users in the coverage area of ​​the base station, and there is no research o...
