En anglais seulement

Radio communication is an essential component of Canadas communications system, providing the only means of communicating with moving vehicles and isolated locales. This historical assessment describes how Canadians have used radio as a tool of trade and commerce, war, and national and international communication. It also traces the scientific and technological development of radio from its beginnings as wireless telegraphy in the late 19th century up to the development of the first radio-based mobile telephones in the mid-20th century.
