What I going to show you next definitely is beyond a WiFi heatmap. WiFi signal is something that we cannot see and feel. In fact, our life becoming more and more depend on something we cannot see and feel. Do you ever wonder how actually the WiFi look like? Sound ridiculous? Yes, it is ridiculous!
A student Luis Hernan from UK invented some custom-made instrument can detect the WiFi signal strength and generate a series of photo to show you how exactly WiFi look. It continuously scan for RF signal and transforms the wave to some colour line. Blue is strongest signal and red is lowest. Different place and surrounding will generate different pattern of colour wave. The colour wave will disturb by mobile phone signal, gesture of human, and any moving item.
Believe it or not. Enjoy the WiFi art!
