Method for predicting electromagnetic radiation level of surrounding environment of TD-LTE mobile communication base station

Abstract

The present invention provides a method of predicting an electromagnetic radiation level of a surrounding environment of a TD-LTE mobile communication base station. The method comprises a three-dimensional space prediction mode. The sum of a radiation power flux density of a downlink reference signal and a control channel and a radiation power flux density of a physical shared signal is an overall average electromagnetic radiation level of the downlink channel. The method of predicting the electromagnetic radiation level of the surrounding environment of the TD-LTE mobile communication base station can deliver an accurate prediction result.

Background technique [0002] With the development of science and technology, electromagnetic radiation equipment of public frequency is more and more used in various fields of production and life, so that the level of electromagnetic radiation of various frequencies in space is getting higher and higher. In recent years, mobile communication has become an important part of people's daily life, and the environmental protection of electromagnetic radiation of mobile communication has become a hot issue widely concerned by the public.

[0006] This model does not consider the directionality of the electromagnetic waves emitted by the mobile communication base station. The prediction results are relatively conservative and lack of pertinence, especially the focus points in the non-main lobe direction. The deviation from the field measurement results is large, and it cannot reflect the electromagnetic waves around the base station very well. The distribution of radiation

If this prediction model is directly used, the prediction results of the electromagnetic radiation level of the base station in the environmental impact assessment stage will be significantly increased, and the deviation between the proportion of unqualified base stations that do not meet the site selection requirements and the actual situation will be significantly increased.

[0007] Subsequent research has been carried out on the theoretical prediction prediction mode of electromagnetic radiation levels of GSM and TD-SCDMA mobile communication base stations. Due to the transmission principle, power allocation mechanism and frame structure of TD-LTE mobile communication base stations are different from those of GSM and TD-SCDMA mobile communication base stations. Therefore, the prediction method of the electromagnetic radiation level of the TD-LTE mobile communication base station is essentially different from that of the GSM and TD-SCDMA mobile communication base stations.
