ABSTRACT
The WiFi router is a very common device that is found in nearly every office and in 90% houses in urban areas. The effects of nonionizing electromagnetic radiation of frequency range from 3.5 GHz to 8.0 GHz that is emitted from the devices is studied in this manuscript. The electric field is computed around the router and electric field inside the body is also determined. The effects of EM radiation depend upon the factors like frequency, power and time duration of exposure. The electric field and specific absorption rate inside the body of human beings are calculated near the WiFi router at various distances from it. It is observed that at a distance of 1m to 1.4m, SAR is found to be harmful at some frequencies but at 1.5m away from the router the SAR value is safe for all selected frequency range. Therefore, it is suggested after this theoretical study that a distance of 1.5m should be maintained from the WiFi router for the given frequency band.
