What
is broadband?
BROADBAND - A
transmission facility having a bandwidth sufficient to carry multiple
voice, video or data channels simultaneously. Each channel occupies (is
modulated to) a different frequency bandwidth on the transmission medium
and is demodulated to its original frequency at the receiving end.
Channels are separated by "guardbands" (empty spaces) to
ensure that each channel won't interfere with its neighboring channels.
This technique is used to provide 50 CATV channels on one coaxial cable.
