Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] A method for estimating the position of a maximum exposure point of electromagnetic radiation of a base station according to the present invention comprises the following steps:

[0023] 1) Combined with the COST-231 Walfish-Ikegami path loss model considering the relevant parameters of the transmitting antenna and the line-of-sight, the expression of the receiving power at a certain point is obtained;

[0024] 2) Deriving the received power expression in step 1 with respect to x, where x is the horizontal distance from the receiving point to the transmitting antenna of the base station, and determining the position of the maximum exposure point of the electromagnetic radiation of the base station.

[0025] In the step 1, in combination with the COST-231 Walfish-Ikegami path loss model considering the relevant parameters of the transmitting anten...

Abstract

The invention discloses a base station electromagnetic radiation maximum exposure site position estimation method comprising the following specific steps: firstly using a COST-231 Walfish-Ikegami route loss model considering emission antenna correlation parameters and stadia conditions to obtain a certain point location reception power expression; using the certain point location reception power expression to solve the horizontal distance x from the reception point to the base station emission antenna, and determining the base station electromagnetic radiation maximum exposure site position. The method considers the base station emission antenna height, the base station maximum emission power and the reception antenna height information, thus estimating the base station electromagnetic radiation maximum exposure site position; the method can accurately, simply and fast locate the base station electromagnetic radiation maximum exposure site position.

Description

technical field [0001] The invention relates to a method for estimating the position of the maximum exposure point of electromagnetic radiation of a base station. Background technique [0002] With the rapid development of the mobile communication industry, a large number of new base stations have been put into use, and the environmental impact of base station electromagnetic radiation has become an issue of increasing public concern. When measuring the electromagnetic radiation of the base station, it is often necessary to find the maximum exposure point of the electromagnetic radiation of the base station as soon as possible, so as to analyze the electromagnetic radiation and environmental impact assessment of the maximum exposure point. However, currently, no effective method has been proposed for estimating the position of the maximum exposure point of the base station's electromagnetic radiation. [0003] In view of the above problems, the present invention proposes a ...
