to
occur.
The
pros
is
obvious,
the
cons
is
the
overhead
for
transmission.
So,
in
a
clean
environment,
higher
fragment
threshold
can
be
an
option
to
increase
throughput.
Fragmentation
will
be
triggered
by
setting
the
Fragment
Threshold,
usually
in
Byte
‐
length.
Only
when
the
frame
size
is
over
the
Threshold,
fragmentation
will
take
place
automatically.
RTS
Threshold:
RTS
Threshold
is
in
the
range
of
1~2346
byte.
The
default
is
2346
byte.
The
main
purpose
of
enabling
RTS
by
changing
RTS
threshold
is
to
reduce
possible
collisions
due
to
hidden
wireless
clients.
RTS
in
AP
will
be
enabled
automatically
if
the
packet
size
is
larger
than
the
Threshold
value.
By
default,
RTS
is
disabled
in
a
normal
environment
supports
non
‐
jumbo
frames.
Short
Preamble:
By
default,
it’s
“
Enable
”.
To
Disable
is
to
use
Long
128
‐
bit
Preamble
Synchronization
field.
The
preamble
is
used
to
signal
"here
is
a
train
of
data
coming"
to
the
receiver.
The
short
preamble
provides
72
‐
bit
Synchronization
field
to
improve
WLAN
transmission
efficiency
with
less
overhead.
Tx
Burst:
By
default,
it’s
“
Enable
”.
To
Disable
is
to
deactivate
Tx
Burst.
With
TX
burst
enabled,
AP
will
send
many
packets
in
a
burst,
without
collision
detection
and
RTS/CTS
for
each
packet.
TX
Burst
have
better
throughput
but
cause
interference
with
other
APs
using
the
same
channel.
802.11g
Protection
Mode:
By
default,
it’s
“
Enable
”.
To
Disable
is
to
deactivate
802.11g
Protection
Mode.
Protection
mode
use
RTS/CTS
to
prevent
interference
with
other
APs
and
802.11b
peers,
and
disabling
it
will
save
transmission
time
used
by
RTS/CTS.
RTS/CTS
threshold
is
effective
only
when
802.11g
protection
mode
is
made
enable.
