The primary reason for implementing this function is to minimize the collision between hidden … WebTo avoid this situation, we can use RTS-CTS mechanism. Any 802.11 device that wishes to transmit in the medium should send RTS (Request to Send) frame – requesting for medium access to the AP. The latter then responds with CTS (Clear to Send) frame that includes the Duration field, which helps the station to set its NAV timer.
