RTS/CTS

A hidden node occurs when two stations are within range of the same access 
point, but are not within range of each other. The following figure illustrates a 
hidden node. Both stations (STA) are within range of the access point (AP) or 
wireless gateway, but out-of-range of each other, so they cannot "hear" each 
other, that is they do not know if the channel is currently being used. Therefore, 
they are considered hidden from each other. 

Figure 89   

RTS/CTS

When station 

A

 sends data to the AP, it might not know that the station 

B

 is 

already using the channel. If these two stations send data at the same time, 
collisions may occur when both sets of data arrive at the AP at the same time, 
resulting in a loss of messages for both stations.

RTS/CTS

 is designed to prevent collisions due to hidden nodes. An 

RTS/CTS 

defines the biggest size data frame you can send before an RTS (Request To 
Send)/CTS (Clear to Send) handshake is invoked.

When a data frame exceeds the 

RTS/CTS 

value you set (between 1 to 2432 

bytes), the station that wants to transmit this frame must first send an RTS 
(Request To Send) message to the AP for permission to send it. The AP then 
responds with a CTS (Clear to Send) message to all other stations within its range 
to notify them to defer their transmission. It also reserves and confirms with the 
requesting station the time frame for the requested transmission.

Stations can send frames smaller than the specified 

RTS/CTS 

directly to the AP 

without the RTS (Request To Send)/CTS (Clear to Send) handshake. 

You should only configure 

RTS/CTS

 if the possibility of hidden nodes exists on 

your network and the "cost" of resending large frames is more than the extra
