Definition
The radio spectrum is "the full range of frequencies suitable for radio communication."[1]
Overview
The radio spectrum is segmented into bands of radio frequencies and typically measured in cycles per second, or hertz.[2]
The width of the radio spectrum is called the bandwidth of the signal. More broadly, the radio frequency spectrum consists of all the radio frequencies used for radio communications.
Radio spectrum in the United States has been assigned to a variety of services, including commercial mobile radio service, private mobile radio, satellite services, mobile wireless services and fixed wireless services, including broadcast broadband access, point-to-point and backhaul services.
"To achieve maximum use of the spectrum, the Federal Communications Commission has prescribed rules and regulations to be followed by licensed radio operators and authorized radio stations. Scrupulous observance of these rules and regulations is necessary to prevent harmful radio interference."[3]
