Bandwidth Utilization:
Multiplexing and
Spreading
6.1
, Note
Bandwidth utilization is the wise use of
available bandwidth to achieve
specific goals.
Efficiency can be achieved by
multiplexing; privacy and anti-jamming
can be achieved by spreading.
6.2
, 6-1 MULTIPLEXING
Whenever the bandwidth of a medium linking two
devices is greater than the bandwidth needs of the
devices, the link can be shared. Multiplexing is the set
of techniques that allows the simultaneous
transmission of multiple signals across a single data
link. As data and telecommunications use increases, so
does traffic.
Topics discussed in this section:
Frequency-Division Multiplexing
Wavelength-Division Multiplexing
Synchronous Time-Division Multiplexing
Statistical Time-Division Multiplexing
