RF exposure from ten 5G beamforming cell towers (3.6 GHz band) in Germany

Abstract

Overview

This study investigates the metrological recording and analysis of immissions from 5G beamforming antennas operating in the 3.6 GHz band. This research utilized measurement methods for assessing current, typical, and maximum possible immissions influenced by the time-varying behavior of antennas.

Methodology & Findings

• Measurements were taken at 100 systematically chosen points near ten 5G beamforming base stations.
• Maximum immissions ranged from 0.2% (0.15 V/m) to 28.9% (17.6 V/m) of the field strength limit, with a median of 4.7% (2.9 V/m).
• Typical usage scenarios (e.g., ARD live stream) showed slightly higher immissions than unprovoked conditions, suggesting varying radiation levels based on usage intensity.
• The placements of the antennas and natural obstacles like vegetation significantly influenced the immission levels.

Conclusion

The findings highlight the complexities of EMF radiation from 5G technologies and their dependency on multiple factors including environment and antenna positioning. The data shows potential variability and moments of higher emissions, which could be relevant for assessing long-term exposure risks to human health.
