Research on the Impact of 5G Terminals on Electromagnetic
In order to solve the above two questions, we use the base station electromagnetic radiation function of the EMF meter to measure a 5G base station, and use the 5G NR
Spectrum of 5G signals with 0 % (purple), 10 % (yellow), 50 % (green), and 100 % (blue) load. 4. Measurement setup and environment The experimental part of the research consists of a measurement campaign to assess the human exposure to EMF in the surroundings of an active 5G base station.
Quantification of the uncertainty that the fluctuation in 5G signal levels induces in the assessment of electromagnetic fields exposure is provided. The use of broadband field probes for 5G exposure assessment is still possible under certain considerations and correcting the results considering the base station load and beamforming effects.
Fast variation of the user load and beamforming techniques may cause large fluctuations of 5G base stations field level. They may be underestimated, resulting in compliance of base stations not fitting the requirements. Apparently, broadband field meters would not be adequate for measuring such environments.
This agrees with measurements done in other countries whose authors conclude that the exposure to 5G signals is limited, , , but this does not assure the base station compliance as full load situation should be considered for such assessment. It also shows that the increase in the EMF field is due to the induced data traffic.
