Do 5G base stations need a field meter?

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.

Is forcing a base station with an extra load a solution?

Results show that forcing the base station with an extra load seems to be a solution for assessing human exposure with simple broadband field meters, as the RMS E-field levels match or overestimate the values obtained with other methods.

Does a 5G base station increase field levels?

Adding the 5G systems does not significantly increase the overall field levels in the surroundings of the base station, in normal working conditions, compared to those of the previous generation. This has been checked during a measurement campaign in the surroundings of a 5G base station under operation.

Can broadband equipment be used to measure EMF field level?

Thus, broadband equipment can still be used for assessing the EMF field level when measurements are done by forcing an extra load of the station, as it uses to overestimate the field levels. The largest differences in the values measured by the different methods happen at location 7, and especially at location 4.

Can broadband field probes assess 5G base stations compliance?

This paper analyzes the feasibility of assessing the 5G base stations compliance using broadband field probes and compares their performance with alternative methodologies and equipment.

What are EMF field values at each location in V/M?

EMF field values at each location in V/m (worst-case of exposure). Fig. 13. E-field extrapolated measurement results from the different methodologies. As happened with the broadband instrument measurements, those performed with the SA and DTS are well below reference level, which is 61 V/m .
