Generally, it is defined as a high-speed, high-capacity transmission medium that helps in transmitting large amounts of data in the form of signals from multiple independent network carriers. Furthermore, in network engineering the term is used to mention the method that allows two or more signals to share a medium simultaneously. This transmission is normally done on a single coaxial or fiber - optic cable by establishing different bandwidth channels. Broadband service can support a wide range of frequencies and helps in transmitting data, voice and video over long distances. It not only helps in their transmission but also aims to have a high speed, high quality, low cost and an easy to use Internet connection at home.

Broadband services are delivered mainly through telephone lines, cable connections, via one or two way satellite systems and even by radio. Based on its mode of transmission, broadband is classified further into four main types: The Asymmetric Digital Subscriber Line (ADSL) cable broadband Service satellite broadband Service wireless broadband Service Adsl is unique with its typical characteristic style to transmit data in one direction than the other. It primarily uses an analogue modulation scheme, unlike others using band technology based modulation.
