Light Beams To Map Out WiFi Networks

With new technologies being introduced to the world every single day, there is no doubt about the fact that mankind is on the threshold of a major surge in technological advance, a development which should see us emerging into an unexplored and unknown realm.

Wireless networks might have been invisible to the human eye until now, but new technological innovations and modern day creative photography could soon change all that. Luis Hernan, a Ph.D. student at the Newcastle University, used an instrument known as the Kirlian Device to allow wireless networks become visible to the human eye.

How did he manage to do this? He simply took the Kirlian Device and made it scan wireless networks. The signal strength was then translated into LEDs and the instrument was used to capture the networks with the help of long exposure photography. The end result was a vibrant beam of light that looked half stunning and half ghastly.

According to Hernan, the device emits a variety of colors that allow you to see how the wireless network in question is behaving. The colors showcase the difference in signal strength, with the greater ones being shown as red and the lighter ones being shown as blue. Hernan has also developed a Smartphone app that can be used by people around the globe to capture images of their personal wireless networks.

The study was conducted as a part of an initiative where Hernan used several disciplines such as photography, performance, programming, electronics and design and blended them together. The Kirlian Device has been named after a Russian inventor, Semyon Davidovich Kirlian, the main responsible for developing the photographic technique which could capture electrical coronal discharges, i.e., the glow that is usually seen around metal conductors that carry high levels of voltage.

Kirlian photographs of wireless networks were recently showcased in an exhibit known as “The Secret Body of Wireless” at the Newcastle University School of Architecture. Hernan had also created an art installation of several Android phones that were hanging from the ceiling and running a modified version of the Kirlian Device app. This allowed the visitors coming to the exhibition to check out exactly how the WiFi networks in the room changed from one form to the other. Visitors could also check out versions of the mobile app that were designed for the Google Glass.

Hernan states that his main motivation behind developing the WiFi imaging technique was to understand how the technologies were influencing and changing the way people live, especially in terms of changing the way one looks at space and understands architectural space.

Society’s dependence and ever increasing reliance on gadgets, technologies, Smartphones, laptop computers and tablets made people search for mobile signals and WiFi networks which began to change the way people understand space. Modern day inventions have showcased an entirely unique dimension to space, particularly when people begin remaping the way in which spaces are patterned, with certain spots becoming more important than the rest as they happen to be the only spots from which the internet can come through.
