Currently many in the industry can’t come to an agreement as to what “broadband” actually means. In Telecommunications, broadband provides multiple channels of data through a single communications mechanism. It allows for a wide band of available frequencies; because of this, information can be sent on many different frequencies. This allows for more information to be transmitted in a given period of time. Obviously, the wider the band, the more information it can carry and at a faster speed. A broadband communications network can be divided and shared by multiple signals, including voice, audio, video, and internet all at once and over long distances. So essentially, broadband is a high speed, high data capacity medium that can carry signals from multiple network s. This is achieved through a single fiber optic cable by establishing different bandwidth channels which can carry a wide range of frequencies. For example, cable television uses broadband to deliver dozens of channel signals over a single cable.
Broadband usually gets confused with bandwidth which is the amount of data that can be carried from one point to another in a given period of time. Sources
