Problems solved by technology

The current evaluation method for base station electromagnetic radiation can only measure the base station one by one. However, the number of mobile communication base stations is large and the types are complex. It is a difficult task to evaluate the electromagnetic radiation intensity of all base stations in an area. There is a lack of a way to measure the electromagnetic radiation intensity The evaluation method of classifying similar base stations, so that by accurately measuring one of the base stations with similar electromagnetic radiation intensity, the electromagnetic radiation intensity of other similar base stations can be evaluated
In the published patent technology or literature, this problem cannot be solved at present

Abstract

The invention discloses a base station electromagnetic radiation intensity similarity estimation method. According to the method, the interval probabilities of the electromagnetic radiation intensityof a reference base station and comparison base stations are put into statistics; electromagnetic radiation intensity similarity between the comparison base stations and the reference base station iscalculated according to an interval probability difference value matrix; base stations in a region which have similar electromagnetic radiation intensity are classified according to the electromagnetic radiation intensity similarity between the base stations; and therefore, the efficiency of the evaluation of the electromagnetic radiation intensity of the base stations can be improved, and the classified management of the base stations according to the electromagnetic radiation intensity can be facilitated. According to the method of the invention, the electromagnetic radiation intensity similarity between the comparison base stations and the reference base station is calculated according to the interval probabilities of the electromagnetic radiation intensity of the base stations, and therefore, the base station electromagnetic radiation intensity similarity estimation method is effective.

Description

technical field [0001] The invention relates to a method for evaluating the similarity degree of electromagnetic radiation intensity of a base station. Background technique [0002] Due to the development and progress of mobile communication technology, the number of mobile communication base stations has grown rapidly. With the upcoming fifth-generation mobile communication technology (5G), the number of 5G communication base stations will reach even more. As the most important source of electromagnetic radiation in life, mobile communication base stations cannot ignore the safety of electromagnetic radiation. The current evaluation method for base station electromagnetic radiation can only measure the base station one by one. However, there are a large number and complex types of mobile communication base stations. It is a difficult task to evaluate the electromagnetic radiation intensity of all base stations in an area. There is a lack of a way to measure the electromagne...
