The infosphere* relies on an intricate network of signals, wired and wireless, that support it. We are completely surrounded by an invisible system of data cables and radio signals from access points, cell towers and overhead satellites. Our digital lives depend on these very physical systems for communication, observation and navigation. The Architecture of Radio is a site-specific iOS and Android application that visualizes this network of networks by reversing the ambient nature of the infosphere; hiding the visible while revealing the invisible technological landscape we interact with through our devices.
