Seeing in the wifi and cellular spectrum

I’ve often wondered what the world would look like if we could see the wifi and cellular spectrum. Would laptops and cell phones be like flash lights and cell towers giant flood lights covering large areas and visible for miles? Imagine this ‘light’ going through buildings and illuminating the inside like the walls were made of glass.

It’s not exactly what I’ve imagined but checkout this cool video which gives a two dimensional view of wifi signal strength (original source).
