it is to prevent the wasting time of resending a long packet that is lost.
The RTS/CTS Threshold is a station initiates the process by sending a
RTS frame, the other ends receives the RTS and responds with a CTS
frame, the station must receive a CTS frame before sending the data
frame. This is to prevent the collisions by each station. Choose a
setting within a range of 1 to 1247 bytes. It is recommend to limit a
long packet to prevent each station
waiting too long to transmit a data.
