Radio,

the oldest broadcast service, uses 10 kHz for each terrestrial broadcast license assigned by the FCC in AM and FM bands separated by geographic regions.[1]

Overview Edit

"Radio . . . started out as a point-to-point communication technology, a wireless telegraph. After about two decades of experimentation, it became primarily a broadcast medium. . . . [I]n the last few decades, with the development of cellular services, radio transmission has started to move back to its roots as a point-to-point communications service."[2]

The radio industry also uses digital audio broadcasting (DAB) technology.
