Signals Emitted From Wi-Fi Are Not Harmful For Human Body, Reveals a New Research

According to a general perception of people, Wi-Fi technology is considered to have a negative impact on the health of human body. In contrast to this belief, a recent study claims that Wi-Fi is not actually harmful to health, rather just a myth is created.

Kenneth r. Foster, a bioengineering professor at the University of Pennsylvania carried out a study which indicated that Radio Frequency (RF) signals emitted by Wi-Fi are a lot less than the safety guidelines set for radio waves. Yet, many believe that these signals are harmful despite the claim that the RF of Wi-Fi is lower than the standard frequency.

These signals can be harmful for users if they reach the exposure level which usually happens when a medical process fails or near the high-powered transmitters. But when it comes to Wi-Fi, the exposure of RF is quite less.

Federal Communications Commission (FCC) checks every wireless device before it goes out to market for sale in the US to ensure that it meets the safety standards.

People also have false beliefs about radiations, which they think is overexposure because of x-rays.


Signals transmitted through Wi-Fi devices are in two bands of RF spectrum, around 2.45 GHz and 5 GHz, and this energy is not hazardous to human health.

According to the study, the frequency of Wi-Fi is lower than that of a mobile phone. Even if there are a number of people using Wi-Fi in a room, in its full swing, still, the frequency will not cross that of a smartphone.



"If health agencies eventually conclude that radio frequency signals from Wi-Fi are hazardous in some way, schools can revise their policies accordingly. In light of half a century of research on the biological effects of radio frequency energy, such a conclusion seems unlikely.", claimed Kenneth R. Foster.
