Term:
broadband
Definition: a communications channel having a bandwidth characterized by high data transmission speeds (10,000 to 500,000 bits per second). Often used when describing communications systems based on cable television technology. In the 802 standards, a system whereby information is encoded, modulated onto a carrier, and band-pass filtered or otherwise constrained to occupy only a limited frequency spectrum on the coaxial transmission medium. Many information signals can be present on the medium at the same time without disruption provided that they all occupy nonoverlapping frequency regions within the cable system's range of frequency transport. |
