Wi-Fi signals exist. We use them. We associate our smart devices and they warn us whenever some signals are available.
Talking about Wi-Fi, the popular technology that allows devices to exchange data wirelessly and follow the IEEE 802.11 standards, of the Institute of Electrical and Electronics Engineers and the Alliance which was set up in order to follow this single template.
Where are they, though? We see the router, we see that our devices are connected, but what about their signals? How would the world be if we could see them?
The Wi-Fi is energy fields which are transmitted as waves.
These waves have a specific height, distance between them and travel with a certain speed. The Wi-Fi waves have a shorter distance between them by radio waves and greater than microwaves and this fact make them remain unaffected by any other waves.
The Wi-Fi repeaters are essentially antennas that are equipped with a transmission protocol that divides the frequency range into areas called channels. The data is transmitted via any channel. The area of each Wi-Fi field, depending on the type of equipment you use, may reach 20-30 meters and the fields are either spherical or oval.
Of course, various objects in outer space, such as trees, are blocking the signals of Wi-Fi. A router or a broadcast antenna placed outdoors can transmit the signal of up to 100 meters away from the point that it is placed.
Imagine how LSD would be the way we see the world if we could actually see the Wi-Fi in cities that we live. And also consider what crosses through us, when we are in a square as this Syntagma in Athens, or the Trafalgar in London, where there are multiple Wi–Fi signals, cellular antennas, and other electromagnetic fields.
If we could see Wi-Fi signals, we doubt if we could see the buildings that exist around us. Amazing work!
