This project explores the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs. A four-metre tall measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting.

While we were mapping out tiny RFID fields, we wondered what it would be like to apply the light painting process to larger-scale fields of Bluetooth, WiFi, GSM and 3G. What if we built huge light painting apparatus that could map out architectural and city-scale networks in the places and spaces they inhabited? We’re still very interested in understanding radio and wireless networks as one of the substrates essential to contemporary design practice.
