tab
on
the
Toolbar
allows
you
to
set
four
levels
of
accuracy
for
RF
computations
with
1
being
the

Computation
time
for
creating
RF
maps
increases
with
the
accuracy
level.

the
floor
model
and
coverage
together.
Select
the

This
view
displays
color
‐
coded
RSSI
distribution
over
and
around
the
perimeter
of
the
current
layout.
It
helps
you
analyze
the
security
exposure
due
to
spillage
of
the
signals
outside
the
perimeter
of
the
current
layout.
You
can
minimize
the
security
threats
from
war
drivers
and
eavesdroppers
based
on
the
results
of
the
Spillage
View
.
Planner
assumes
the
area
outside
the
layout
to
be
free
space
for
RF
prediction.
Higher
Sensor
coverage
outside
the
perimeter
of
the
layout
indicates
a
better
coverage
for
security
exposure.
With
larger
coverage,
a
device
that
is
far
away
from
the
layout
perimeter
can
also
be
detected
by
the
Sensor
and
the
transmission
can
be
prevented,
if
found
malicious.
