Advanced
Setup
To
achieve
optimal
wireless
performance,
it
is
necessary
to
tweak
advance
setting
per
requirements
properly,
not
necessary
higher
the
better
or
lower.
The
administrator
can
change
the
RTS
threshold
and
fragmentation
threshold
settings
for
the
system.
Please
click
on
Wireless
‐
>
Advanced
Setup
and
follow
the
below
setting.
Slot
Time
:
Slot
time
is
in
the
range
of
1~1489
and
set
in
unit
of
microsecond
.
The
default
value
is
20
microsecond.
Slot
time
is
the
amount
of
time
a
device
waits
after
a
collision
before
retransmitting
a
packet.
Reducing
the
slot
time
decreases
the
overall
back
‐
off,
which
increases
throughput.
Back
‐
off,
which
is
a
multiple
of
the
slot
time,
is
the
random
length
of
time
a
station
waits
before
sending
a
packet
on
the
LAN.
For
a
sender
and
receiver
own
right
of
the
channel
the
shorter
slot
time
help
manage
shorter
wait
time
to
re
‐
transmit
from
collision
because
of
hidden
wireless
clients
or
other
causes.
When
collision
sources
can
be
removed
sooner
and
other
senders
attempting
to
send
are
listening
the
channel(CSMA/CA)
the
owner
of
the
channel
should
continue
ownership
and
finish
their
transmission
and
release
the
channel.
Then,
following
ownership
of
the
channel
will
be
sooner
for
the
new
pair
due
to
shorter
slot
time.
However,
when
long
duration
of
existing
collision
sources
and
shorter
slot
time
exist
the
owners
might
experience
subsequent
collisions.
When
adjustment
to
longer
slot
time
can’t
improve
performance
then
RTS/CTS
could
supplement
and
help
improve
performance.
