Fragmentation Threshold: If the packet size is smaller than the
preset Fragment size, the packet will not be segmented.
Fragmentation of the PDUs (Package Data Unit) can increase the
reliability of transmissions because it increases the probability of
a successful transmission due to smaller frame size. If there is
significant interference present, or collisions due to high network
utilization, try setting the fragment size to send smaller fragments.
This will enable the retransmission of smaller frames much faster.
However, it is more efficient to set the fragment size larger if very
little or no interference is present because it requires overhead to
send multiple frames.
Beacon Interval: Set the interval value of beacon between
synchronized frames. These synchronous frames also contain
indication of frames that need to transmit to the power-saved
stations.
DTIM: Set the Delivery Traffic Indication Message (DTIM) interval
value. The DTIM indicates how often the MAC layer forwards
multicast traffic. This parameter is necessary to accommodate
stations using Power Save mode. In order to maximize the
utilization of channels, broadcast data is not transmitted every
beacon for stations in Power Save mode. These power-saved
stations must wake up to receive broadcast data at the DTIM
interval. The DTIM is the interval between two synchronous
frames with broadcast information. If you set the value to 2, the
access point will save all multicast frames for the BSS and
forward them after every second beacon. Having smaller DTIM
intervals delivers multicast frames in a more timely manner,
causing stations in Power Save mode to wake up more often and
drain power faster. Having higher DTIM values, though, delays
the transmission of multicast frames.
