RTS is a mechanism for requesting transmission, that is, transmission. Look at the time slot of RTS. If you write 0 when sending, you will send an RTS message every time to apply for sending a data packet.
When set to 0, it means that the collision will be detected as long as the data packet is sent, and the AP will send RTS signal.
When it is set to 2347, it means that RTS signals will never be sent, because there are no packets larger than 2347.
hope this helps
