Wireless communication surrounds people at all times, even though it cannot be seen. Signals from Wi-Fi routers, Bluetooth devices, and mobile networks constantly travel through homes and cities unless blocked by heavy shielding. A France-based digital artist has developed a way to visually represent this invisible activity using light and low-cost computing hardware.
The creator, Théo Champion, who is also known online as Rootkid, designed an installation called Spectrum Slit. The project captures radio activity from commonly used wireless frequency ranges and converts that data into a visual display. The system focuses specifically on the 2.4 GHz and 5 GHz bands, which are widely used for Wi-Fi connections and short-range wireless communication.
The artwork consists of 64 vertical LED filaments arranged in a straight line. Each filament represents a specific portion of the wireless spectrum. As radio signals are detected, their strength and density determine how brightly each filament lights up. Low signal activity results in faint and scattered illumination, while higher levels of wireless usage produce intense and concentrated light patterns.
According to Champion, quiet network conditions create a subtle glow that reflects the constant but minimal background noise present in urban environments. As wireless traffic increases, the LEDs become brighter and more saturated, forming dense visual bands that indicate heavy digital activity.
