The artist and researcher Nikolai Lamm tried to answer this unusual question. To do this, he used a technique developed by Edward Tufty, a renowned researcher in the field of information design.
As you know, cellular networks are defined territories in the form of hexagonal cells, which are covered with a signal from the antennas of cellular towers. Each tower has three sets of directional antennas spaced 120 degrees to each other for circular signal propagation. Each antenna is in turn connected to a base station, which transmits and receives signals at predetermined frequencies.
Nikolai Lamm recruited two University of Illinois professors Danilo Erricolo and Fran Haraskevich as consultants. It was they who helped him create a visual image of the signals from cellular antennas.
The result was unusual photographs of Washington, Chicago, New York and Hollywood, in which the signals of millions of cell phones took on color and shape.
By the way, this is not the first visual experiment of Nikolai Lamm. Not so long ago, he tried to portray what a person would look like in 100 thousand years.
