Problems solved by technology

[0002] With the rapid development of the communication industry, mobile communication has penetrated into all aspects of social life, bringing great convenience to people, and also causing people to worry about the electromagnetic radiation of mobile communication base stations. The electromagnetic radiation of communication base stations and the base station antenna Parameters such as transmit power, gain, and loss are related to the path loss in the propagation process, and the power given by the base station manufacturer is not the actual transmit power of the antenna port. In the current published literature and patents, there is no method for evaluating the electromagnetic radiation of a base station for the actual transmit power and diffraction loss of the antenna port at the same time.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with embodiment.

[0023] The present invention is carried out outdoors, and the object of implementation is a TD-LTE base station. The base station transmit antenna gain G=15dBi, the antenna system loss L=6.2dB, and the transmit wavelength λ=0.115m. There are obstacles between the base station and the evaluation. The horizontal distance d of the base station 1 = 10m, the relative height of the obstacle relative to the base station h = 3m, the measurement equipment uses KEYSIGHT N9918A portable spectrum analyzer and receiving antenna.

[0024] A base station electromagnetic radiation evaluation method in a diffraction environment of the present invention comprises the following steps:

[0025] 1), according to the horizontal distance of the obstacle from the base station, the horizontal distance of the obstacle from the evaluation point, and the relative height of the obstacle relative to the base sta...

Abstract

The invention discloses a base station electromagnetic radiation evaluation method in a diffraction environment. The method obtains the diffraction parameters according to the horizontal distance of the obstacle from the base station, the horizontal distance of the obstacle from the evaluation point, and the relative height of the obstacle relative to the base station , so as to obtain the diffraction loss, combined with the actual transmit power of the antenna port obtained by the downlink ratio of the base station, the network load ratio of the base station system, the single-channel transmit power of the base station, the efficiency of the smart antenna, the number of base station channels and the number of carriers of the base station, and thus obtain the evaluation point The electromagnetic radiation intensity of the base station. The evaluation method proposed by the invention has great reference value for the evaluation of base station electromagnetic radiation under the diffraction environment.

Description

technical field [0001] The invention relates to a base station electromagnetic radiation evaluation method in a diffraction environment. Background technique [0002] With the rapid development of the communication industry, mobile communication has penetrated into all aspects of social life, bringing great convenience to people, and also causing people to worry about the electromagnetic radiation of mobile communication base stations. The electromagnetic radiation of communication base stations and the base station antenna Parameters such as transmit power, gain, and loss are related to the path loss in the propagation process, and the power given by the base station manufacturer is not the actual transmit power of the antenna port. In the current published literature and patents, there is no method for evaluating the electromagnetic radiation of a base station that simultaneously targets the actual transmit power and diffraction loss of the antenna port. [0003] Aiming a...
