Accurately assessing exposure to radio frequency electromagnetic fields from 5G networks

Abstract

Overview

This study delves into the exposure to radio frequency electromagnetic fields (RF EMF) emanating from 5G networks, particularly those with massive MIMO base stations operating at 3.5GHz.

Findings

• Meticulous measurements conducted around street-level base stations in commercial 5G networks revealed that the EMF contribution from these networks was under 10% even with maximum traffic induction.
• The peak exposure levels were significantly lower, at 150 to 200 times below international safety limits determined by ICNIRP.

Conclusion

5G networks demonstrate superior spectrum efficiency and utilize advanced antenna technologies leading to lower RF EMF exposure compared to older generations of mobile networks. Despite the challenges in assessing compliance with RF EMF safety regulations due to the dynamic nature of beam steering in MIMO systems, stringent international guidelines ensure continued safety with conservative limits rigorously adhered to in national regulations.
