There are Preamble Type , Fragmentation Threshold, and
RTS/CTS Threshold setting under this mode.
u Preamble Type (Short/Long) : Preamble is the first
subfield of PPDU, which is the appropriate frame format
for transmission to PHY (Physical layer). There are two
options, Short Preamble and Long Preamble. The Short
Preamble option improves throughput performance.
u Fragmentation threshold : The size at which packets
will be fragmented. Choose a setting within a range of 256
to 2346 bytes.
u RTS Threshold : Minimum packet size to require an RTS
(Request To Send). For packets smaller than this threshold,
an RTS is not sent and the packet is transmitted directly to
the WLAN. This is the option for the RTS Threshold
activation.
