Research on the Impact of 5G Terminals on Electromagnetic Radiation of 5G Base Stations

The Ministry of Ecology and Environment released the “5G mobile communication base station electromagnetic radiation environmental monitoring methods (for trial implementation)” (HJ1151-2020) standard in 2020, which specifies the content, methods and other technical requirements for electromagnetic radiation environmental monitoring of 5G mobile communication base stations. In this standard, it is clearly stated that when monitoring, the monitored mobile communication base station should be in normal working condition, and the 5G terminal equipment should be connected to the monitored 5G mobile communication base station and be in at least one typical application scenario. It is also stated that the 5G terminal equipment and the monitoring equipment probe should be kept within the range of 1–3 m during monitoring. This paper uses frequency-selective electromagnetic radiation field meter (EMF Meter) and 5G NR spectrum analyzer to test different application scenarios of 5G terminals and different relative positions with the EMF probe for different effects on the electromagnetic radiation monitoring values of 5G base stations from several aspects.
