broadband definition

communications
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.
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, e.g. ADSL. A broadband connection is typically always connected, in contrast to a dial-up connection, and 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.
See also baseband, narrowband.
