broadband
adj 1: of or relating to or being a communications network in
which the bandwidth can be divided and shared by multiple
simultaneous signals (as for voice or data or video)
2: responding to or operating at a wide band of frequencies; "a
broadband antenna" [synonym: {broadband}, {wideband}]

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}.
