Amazing photographs bring the WiFi spectrum to life

"The images are created by combining technical and performative components,” he explains. “In the technical, I designed an instrument which continuously prompts for the RSSI (Received Signal Strength Indication) through active scans of WiFi networks. This is in turn represented as colors. The other component is the interpretation of the results…. The device is carried across a space, with the operator improvising movements to reflect the values that are being returned. This process is recorded using long-exposure photography, which registers the trail left by the instrument's movement as a consistent presence in the scene.”

“What you see in the images is a combination of the fluctuations in the WiFi network with the movements of the operator. Colors change depending on the signal strength of a specific point in space. The curved lines are the result of the device's operator moving it across the image. The coloration responds to a perceptual model of warmth. Red signifies the stronger signal strength, whilst blue stands for the weaker.”
