| With issuance of the 4G licenses, the three mobile communication operators have invested a lot of money in planning and construction of 4G base stations to win the popularity of 4G as soon as possible, and get more satisfaction and users. People are enjoying convenience and efficiency from 4G communication technology, at the same time also gradually pay attention to whether the nearby communication base stations are harmful to living environment and physical health. Therefore, how to estimate the electromagnetic radiation of 4G base station so that people can better understand the electromagnetic radiation problem and reduce people’s fear of base station,that is an urgent problem to be solved.The article aim at the electromagnetic radiation problem that people concern about, introduce the core technologies of 4G,origin and factors affecting of electromagnetic radiation, use 4G base station electromagnetic radiation environment evaluation standard as the background to design a detailed monitor program,through theoretical analyse and calculate the electromagnetic radiation of 3G and 4G base stations, and field-test the different 3G and 4G base stations,then compare the theoretical data with the test data. The result shows that the electromagnetic radiation of 4G base station is equal to or lower than the 3G base station. It is proved that the 4G base station will not lead to the increase of environmental radiation, and provide some data support for the electromagnetic radiation environmental impact and evaluation of 4G base station. |
