Radio is the wireless transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light.

Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. It does not require a medium of transport. Information is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude or their frequency. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.

The word 'radio' is used to describe this phenomenon, and television, radio, and cell phone transmissions are all classed as radio frequency emissions.

By addressing radio in terms of what Lyotard (1997:47) calls "stream[s] of cultural capital", scholars can explore the social construction and importance of wireless telegraphy. ^[1] Transmitting messages and information without wires was a major technological achievement, yet one dwarfed by comparison to the social and cultural implications of coming to terms with the novel electromagnetic environment. Indeed, when it first appeared on the social horizon, radio immediately became a significant site of cultural production and contestation. Rather than a type of cultural phenomenon, radio waves continue to function as a “zone of cultural debate” (Appadurai 1996:5).^[2]Pace Adorno and the Frankfurt School’s view of radio as isolating people by encouraging atomized listening, radio, particularly in rural, "isolated" regions sustains imagined--albeit fractal, if not fragmented--communities.
