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.
