Abstract

Accurately assessing exposure to radio frequency electromagnetic fields from 5G networks Accurately assessing exposure to radio frequency electromagnetic fields from 5G networks. Ericsson white paper. GFTL-21:001105 Uen. October 2021. No abstract. Excerpts "Measurements were recently taken in a large number of street-level locations around base stations in a commercial 5G network with massive MIMO base stations operating in the 3.5GHz band [9]. It was found that the contribution from the 5G network to the total environmental RF EMF exposure was less than 10 percent even in the case of 100 percent induced traffic and that the maximum exposure levels from the 5G base stations were 150 to 200 times below the international limits set by the ICNIRP." Conclusion "The high spectrum efficiency and the advanced antenna technologies used by 5G NR lead to lower levels of RF EMF exposure than from earlier generations of mobile networks for comparable services. The base stations in 5G NR networks need to comply with the same RF EMF safety regulations as other radio equipment, and the limits cover all frequency bands used by 5G, including those in the millimeter-wave range. International RF EMF exposure guidelines have recently been published based on the latest available scientific research, with conservative limits that have been or will be adopted in national regulations. Assessing compliance with RF EMF limits may be a challenge for massive MIMO 5G base stations due to dynamic beam steering, but solutions such as envelope beam pattern files together with recommended power reduction factors are available to enable accurate evaluations. The typical overall environmental RF EMF exposure will remain at a small fraction of international limits even with 5G being deployed since the contribution from 5G is relatively small."

Main findings

Street-level measurements around massive MIMO base stations in a commercial 5G network operating at 3.5 GHz found the 5G contribution to total environmental RF EMF exposure was <10% even with 100% induced traffic, and maximum exposure levels from 5G base stations were reported as 150–200 times below ICNIRP international limits. The report concludes that for comparable services, 5G NR technologies lead to lower RF EMF exposure than earlier mobile generations and that typical overall environmental exposure remains a small fraction of international limits, while noting compliance assessment can be challenging due to dynamic beam steering.
