The Utility-intertied Signal Generation & Transfer distributed an Extremely Low-Frequency signal into localized areas of the city. The transmission was achieved by using and altering the electromagnetic field surrounding the power line network. The signal was inaudible and relied on passive bio-reception. A special portable electronic unit was designed to plug into the grid and automatically pattern the pulse-wave signal, distributing it using the electrical network's alternating current. These Conditioning Units were concentrated into five local areas within the city. A website journal generated feedback to review and record reactions. This project was hosted by Lampo.
