Radio spectrum

hide

A range of Radio frequencies that defines allowable or usable channels for specific radio transmission technologies. Radio Spectrum is typically Government regulated in most developed countries and in some cases sold or licensed to operators of private radio transmission systems. (e.g. Cellular telephone operators or Broadcast Television Stations). The range of allocated frequencies are often referred to by the provisioned use. (e.g. Cellular Telephone Spectrum or Broadcast Television Spectrum)

The range of frequencies classified as Radio Spectrum are part of the overall Electromagnetic spectrum comprised of transmissions of a very wide range in frequencies. For reference, Radio spectrum is below or lower in frequency than Infrared spectrum or visible frequencies, also known as light. (see Visible spectrum)
