The findings came from a study conducted by the French spectrum regulator ANFR.
The study compared electromagnetic radiation (EMF) before and after the installation of 5G equipment and found that radiation levels remained similar.
Conducted between October 2020 and October 2021, the study measured EMF levels at nearly 1,650 5G sites. ANFR broke down the results by frequency band.
In the 700 MHz and 2.1 GHz bands, the regulator found that EMF levels remained similar to measurements taken before the installation of 5G.
In the 3.6 GHz band, exposure increased slightly to 0.11 V / m, although this is still significantly less than the exposure limit which is set at 61 V / m.
In a test that involved simulating web traffic with the download of a 1GB file, the regulator found that EMF exposure did rise by about 16%. This is still far below the regulatory limit.
