Radiation measurements in office environment with Wi-Fi, 3G and 4G users

The unprecedented explosion of wireless communications with billions of devices across several wireless and cellular systems, has increased concerns about the human exposure to electromagnetic waves. In this context, this work focuses in office operational environments and the most widely used wireless systems therein, i.e. Wi-Fi and 3G/4G networks, in order to evaluate the radiation levels with 4-5 people working in the room. The results show that even with one Wi-Fi user the radiation level can be higher than the reference level for the whole band, while the corresponding scenario for 3G/4G would be with three users. Also, with three or more users, the 4G levels are ~10% higher than the second higher Wi-Fi.
