UK school Wi-Fi devices emit 5-29 milliwatts of power with exposures well below thermal safety limits at normal distances.

Plain English Summary

Summary written for general audiences

Researchers from the UK Health Protection Agency measured radiofrequency radiation levels from Wi-Fi devices actually used in schools, including laptops and wireless access points. They found that all devices emitted very low power levels (5-29 milliwatts) and produced radiation exposures well below international safety guidelines at distances of 0.5 meters or more. This study provides real-world data on how much Wi-Fi radiation students and teachers are actually exposed to in school environments.

Study Details

Laboratory measurements have been carried out with examples of Wi-Fi devices used in UK schools to evaluate the radiofrequency power densities around them and the total emitted powers.

Unlike previous studies, a 20 MHz bandwidth signal analyzer was used, enabling the whole Wi-Fi signa...
