Is there any Wi-Fi health concerns?

I haven't heard of any research saying that wi-fi is hazardous to health and I think it should not be. If we are talking about electromagnetic waves, there are just too many around us ranging from the TV broadcast network to the cellular phone network. Neither of these are that low powered considering the distance they have to travel through the air and yet we still live with all these waves flowing around us. So, I would worry more about those first before I come to concern about wi-fi.

I have not heard of any. Wi-Fi operates in the same band as microwave ovens, but microwave ovens are dangerous because of the extremely high power. Wi-Fi is very low powered and so could not 'cook' you, even if you were touching the aerials. Some people, however, are more sensitive to electromagnetic waves than others and there is a very, very slight possibility that you are extra-sensitive. Migraines may be caused by all sorts of things (undetected food allergies being one of the commonest and stress and emotional problems probably also being a factor). Try to eliminate all the other possibilities before you definitely blame the Wi-Fi!

in reality this is a question i posed to myself usually about wi-fi techonology,waves and health too!!In reality i never felt bad or something whne i was near an hotspot or wi-fi modem but i can't exclude it can have causes or not!!I nver read or hear about the wi-fi waves are not good for health and i think not....surely we should care about this topic and so it will be useful toconduct a specialized search on this point to understand more about it..for the moment i think not..
