Thanks to the development of new technological devices which have become indispensable for the modern human lifestyle, likewise the wireless technology usage facilitates the data exchange in a highly comfortable way. People wonder very little about the silent exposure to the electromagnetic waves which surround them inside, and outside their homes. This document displays a bibliographic analysis to determine what are the reasons why this type of technology, the Wi-Fi technology, is considered a technology that can become a risk over the human health as well as the living creature's health, caused by the exposure to this wireless communication network. The themes which are developed in this article seek to explain the way Wi-Fi networks operate, why these networks are considered damaging, what adverse effects impacting over human health have been proved by the exposure to this networks, and what are the norms and regulations which limit and rule the use of this technology that becomes into electromagnetic fields. Thus, it is possible to have a clearer idea about the invisible danger this technology represents for the human being, the adverse effects which affect the human health, and the controversy generated at the scientific arena. By defending the studies carried out which prove the theories as well as the economic interests by the distributors of this technology, who do not allow such studies be acknowledged, besides of the lack of regulations by the governments.
