  broadband
  
     <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.
