Abstract

A Theoretical and Experimental Investigation on the Measurement of the Electromagnetic Field Level Radiated by 5G Base Stations Adda S, Aureli T, D'elia S, Franci D, Grillo E, Migliore MD, Pavoncello S, Schettino F, Suman R. A Theoretical and Experimental Investigation on the Measurement of the Electromagnetic Field Level Radiated by 5G Base Stations. IEEE Access 2020 [in press]. doi:10.1109/ACCESS.2020.2998448. Abstract This paper presents some theoretical considerations and experimental results regarding the problem of maximum power extrapolation for the assessment of the exposure to electromagnetic fields radiated by 5G base stations. In particular the results of an extensive experimental campaign using an extrapolation procedure recently proposed for 5G signal is discussed and experimentally checked on a SU-MIMO signal. The results confirm the effectiveness of the extrapolation technique. Starting from an analysis (that represents a further novel contribution of this paper) on the impact of Spatial Division Multiple Access techniques used in 5G on the measurement of EMF level, some indications of possible extension of the technique to the highly complex MU- MIMO case are also given. ieeexplore.ieee.org

Main findings

The paper reports theoretical considerations and results from an extensive experimental campaign on maximum power extrapolation for assessing exposure from 5G base stations. The results confirm the effectiveness of the extrapolation technique, experimentally checked on a SU-MIMO signal, and discuss SDMA impacts with indications for possible extension to MU-MIMO.

Outcomes measured

  • Maximum power extrapolation for assessment of exposure to EMF radiated by 5G base stations
  • Effectiveness of an extrapolation technique for 5G signal measurement
  • Impact of Spatial Division Multiple Access (SDMA) techniques on EMF level measurement
  • Experimental check of extrapolation procedure on SU-MIMO signal
  • Indications for possible extension to MU-MIMO case

Limitations

  • No frequency, measurement levels, or quantitative results are provided in the abstract.
  • No details on experimental setup, locations, or number of measurements are provided in the abstract.
  • The MU-MIMO aspect is described as possible extension/indications rather than fully validated results (per abstract).
