Every person living in a densely populated modern city should know if Wi-Fi is harmful to health. Moreover, it doesn’t matter at all whether he uses a mobile phone, computer, 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. A city is a single "organism" in which the actions of one person, one way or another, are reflected in other residents. A completely different situation in the villages, where even the signal of the base station of the mobile operator can be poorly "caught". Therefore, our article on whether Wi-Fi is harmful will be interesting primarily to residents of cities.- , . Wi-Fi . . , «» Cisco 2970, Wi-Fi , . , .

Wi-Fi technology is one of the varieties of wireless digital data transfer. Each device can operate in both receiver and transmitter mode. If GSM mobile communication is intended primarily for voice communication, then Wi-Fi - for the 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 a connection cable.Is Wi-Fi harmful? For an answer, let's recall the physics course , the electrical engineering section . Back in 1831, the famous scientist M. Faraday discovered an amazing phenomenon called electromagnetic induction. Its meaning is simple: if a conductor forming a closed circuit is affected by an alternating field, then an electric current spontaneously arises (is induced) in its crystal lattice. The more often the field strength lines cross the conductor, the more intensively the current is generated.
Radio waves - this is the same electromagnetic field.Although this moment still does not allow to answer the question “Is Wi-Fi harmful?”, It already makes it possible to assume that the effect on the human body (blood, liquid - excellent conductors) still appears. Often in reviews it is indicated 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’s power supply - it is small and lightweight. A transformer of the same power would have a mass of at least half a kilogram. This was achieved through the use of the impulse principle of conversion. If you reduce the current, but increase the frequency, this allows you to save the output power without changing. Conclusion: it doesn’t matter that GSM power is higher. Wi-Fi has several times more frequency, which completely compensates for the difference. In addition, the abundance of radiation sources causes a phenomenonwave interference, which exacerbates the situation.The topic of the dangers of Wi-Fi is so vast that it cannot be addressed in one article. All data is publicly available, so anyone who considers it necessary can familiarize themselves with it.
