A Canadian point of view on radio-frequency spectrum management

IT IS CUSTOMARY in a discussion of this type to start with the history of the subject as far back as one can obtain records. However, because of limitations of time and space and because it is thought to be more important to look forward, it has been decided to dispense with historical background except to mention that, since Marconi invented the tuned circuit, which required a particular frequency in cycles per second of a radio wave to be used by both transmitter and receiver, the game of the assignment of these numbers representing the frequency of the radio wave has become much more complex.
