Overview
The
Link
Budget
Calculator
is
a
utility
for
calculating
the
expected
performance
of
the

2000
D+
wireless
link
and
the
possible
configurations
for
a
specific
link
range.
The
utility
allows
you
to
calculate
the
expected
RSS
of
the
link,
and
find
the
type
of
services
and
their
effective
throughput
as
a
function
of
the
link
range
and
deployment
conditions.
