With the Wi-Fi network operating, maximum exposure reached 2.6 V/m in the far field region, well below the 61 V/m standard threshold.

Plain English Summary

Summary written for general audiences

Researchers measured Wi-Fi emissions in a typical indoor environment using a dosimeter at 25 locations. With the network operating, maximum exposure reached 2.6 V/m in the far field region with a 90th percentile of 2.2 V/m. Traffic type caused oscillations up to 10 dB at the same position, and mean values differed by around 62 dB between rooms. All measured values were at least 12 times below the 61 V/m standard threshold. Maximum background exposure with the Wi-Fi network off was 0.039 V/m.

Why This Matters

The researchers used the ROS-MLE method to fit exposure levels to statistical distributions. They stated the study is important to raise awareness that radiation from this technology is not negligible and should be controlled. The authors noted the results help clarify epidemiological studies about exposure levels.

Study Details

This paper focuses on the study of emissions in Wi-Fi networks in a typical indoor place, inside a building, by quantifying exposure levels detected in different locations of the house, when router-terminal devices are in specific positions, and also by characterizing the fluctuations arising from the type of traffic which is sent through the network.

The assessment of exposure was carried out collecting measurements with the novel dosimeter ‘EME Spy...

Undoubtedly, this type of study is important to raise awareness that radiation coming from this technology is not negligible, and should be controlled, as well as providing an overview of level fluctuations in a given context. This information helps clarify epidemiological studies about exposure levels.
