RF Sounding is an interactive installation inspired by the metaphor of the impossible human dream to overcome his limits. The installation is defined by an hexagonal area where the user getting inside is able to listen to sounds that are usually not perceived by human ears. Indeed the sound is produced starting from Radio Frequencies (RFs) arising in the presence of a cellular network by shifting RF signals to the audible band and spreading the result all over the installation area. This procedure does not arise from a merely scientific operation, but it also requires an emotional participation from both the composer and the user. The latter is indeed called to induce sounds variations by moving around within the specified area.
The aim of this project is twofold. Indeed, from one side we want to increase end users knowledge of the strength of the power emitted by their cellular phones with respect to the electromagnetic fields produced in the environment, on the other hand we want to provide for an artistic and interactive installation that can also be remotely joined through a web interface.

The installation requires the design and implementation of a localization system based on a wireless sensor network as well as the real time elaboration of RF signals variations.
