Carrier
can
provide
significant
savings
in
operational
expenses.
The
following
considerations
must
be
taken
into
account
when
evaluating
CnC:
•
CnC
can
only
be
used
for
full
duplex
links
where
the
transmitting
earth
station
is
able
to
receive
itself.
•
CnC
can
be
used
in
both
bandwidth
‐
limited
and
power
‐
limited
situations.
•
The
maximum
savings
is
generally
achieved
when
the
original
link
is
symmetric
in
data
rate.
