stations are within range of the same Access Point, but are not within range of each other. Therefore, they are hidden nodes to each other. When a hidden station starts data transmission with the Access Point, it might not notice that the other station is already using the wireless media. When these two stations send data at the same time, they might collide when arriving simultaneously at the Access Point. The collision will most certainly result in a loss of messages for both stations. Thus, the RTS Threshold mechanism will provide the solution to prevent data collisions. When the RTS is activated, the station and its Access Point will use a Request to Send/Clear to send protocol (RTS/CTS). The station will send an RTS to the Access Point, informing that it is going to transmit the data. Upon receipt, the Access Point will respond with a CTS message to all station within its range to notify all other stations to defer transmission. It will also confirm to the requesting station that the Access Point has reserved the channel for transmission.
Fragmentation Threshold: Fragmentation mechanism is used for improving the efficiency when there is high traffic within the wireless network. If you transmit large files in a wireless network, you can enable the Fragmentation Threshold and specify the packet size. The mechanism will split the packet into the packet size you set.
Rate Set: By default, the unit adaptively selects the highest possible rate for transmission. In case of obstacles or interference, the system will step down. Select the Basic Rates to be used among the following options: 1 - 2 (Mbps), 1 - 2 - 5.5 – 11 (Mbps). Select the TX Rate set among the following options, (1 – 2 - 5.5 - 11 Mbps) or (1 - 2 Mbps).
Preamble Type (Short/Long): Preamble is the first sub field of PPDU, which is the appropriate frame format for transmission to PHY (Physical layer). There are two options, Short Preamble and Long Preamble.
