Broadband is a class of communication channel capable of supporting a wide range of frequencies, typically from audio up to video frequencies. A broadband channel can carry multiple signals by dividing the total capacity into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies.

History[]

ISDN was an early precursor to broadband.[1] The term has come to be used for any kind of Internet connection with a download speed of more than 56 kbps, usually some kind of digital subscriber line (DSL). A broadband connection is typically always connected, in contrast to a dial-up connection. A fixed monthly rate is charged, often with a cap on the total amount of data that can be transferred. Domestic broadband connections typically share a telephone line with normal voice calls and the two uses can occur simultaneously without interference..[2]
