A WiFi signal displayed in 3D, something absolutely unimaginable for many, has finally become a reality. A video appeared on CNLohr's YouTube channel, the creator of which decided to implement this seemingly crazy idea and, with the intention of mapping the signal strength, showed the world what a WiFi signal looks like in the third dimension. And he didn't even need any extra complicated equipment for that, somehow he only needed a modem, an LED diode and an ordinary wood chipper.
He reprogrammed the LED to change its color according to the current signal strength. To create a 3D model, he then used the aforementioned wood chipper, with which instead of "just" two dimensions, he could precisely move the diode along the Z axis and thereby create a three-dimensional mapping of the transmitted signal. During his experiments, he also came up with a very interesting insight, which should be known especially to those who are struggling with the well-known problem, where sometimes you simply can't catch WiFi in a certain place on your device, but you can a few centimeters further away. He came to the point that bad (or good) signal coverage in some areas periodically repeats itself, but he did not say whether this is due to magic or something else. For a detailed look at the whole matter, we recommend watching the attached video.
