Everyone living in a densely populated modern city needs to know if Wi-Fi is harmful to health. And it does not matter at all whether he uses a mobile phone, a computer, a tablet or any other device capable of working with wireless communication lines. High-frequency radio waves surround the townspeople everywhere, even in their own beds. The city is a single "organism" in which the actions of one person, one way or another, are reflected in other inhabitants. Quite a different situation in the villages, where even the signal of the base station of the mobile operator can be badly "caught". Therefore, our article on whether Wi-Fi is harmful, will be of interest primarily to the inhabitants of cities.
If someone considers the potential danger illusory, then in its presence it is easy to be convinced. To do this, just turn on the Wi-Fi module of your mobile phone and scan the surrounding area. For certain on the screen there will be a whole list of access points. For example, in our case, only a "modest" Cisco C2970 is found, but if Wi-Fi is harmful, then it is enough to worsen the state of health. As you know, a small drop can gradually destroy even a stone.
As is often the case, most recognized scientists look for an answer to the question of whether Wi-Fi is harmful, useless. Wherever big money is involved, the truth can not be found. Let's try to figure out for ourselves, and to believe the conclusions or not is a personal matter for every person.
Wi-Fi technology is one of the varieties of wireless digital data transmission. Each device can work in the mode of both the receiver and the transmitter. If GSM mobile communication is intended primarily for voice communication, then Wi-Fi is for exchange of binary codes. The operating frequency is rigidly assigned in the standard and is 2.4 GHz. The advantage of such a wireless connection is obvious - there is no need to lay the connecting cable.
So is Wi-Fi harmful? For an answer, let's recall the physics course , the section of electrical engineering. Back in 1831, the famous scientist M. Faraday discovered an amazing phenomenon called electromagnetic induction. Its meaning is simple: if an electric current is induced (induced) on the conductor forming a closed circuit by an alternating field, then in its crystal lattice spontaneously arises. The more often lines of field strength cross the conductor, the more intense the current generation.
Radio waves - this is the very electromagnetic field. Although this point still does not allow to answer the question "Is Wi-Fi harmful?", But it already makes it possible to assume that the impact on the human body (blood, liquid - excellent conductors) is still. Often the reviews indicate that the power of Wi-Fi devices is almost 10 times less than that of GSM phones. However, this is only part of the truth. Look at the computer power supply - it is small and light. The transformer of the same power would have a mass of not less than half a kilogram. This was achieved through the use of the impulse principle of transformation. If you reduce the current, but increase the frequency, this allows you to keep the output power unchanged. Conclusion: it does not matter that the power of GSM is higher. Wi-Fi has several times more frequency, which completely compensates for the difference. In addition, the abundance of radiation sources causes the phenomenon of interference of waves, which aggravates the situation.
The theme of Wi-Fi harm is so vast that it can not be considered within the framework of one article. All data is public, so anyone who thinks fit, can read them.
