When you enable RTS/CTS medium reservation on a suspect “hidden
station”, this station and its Access Point RLM will use a Request to Send/
Clear to Send protocol (RTS/CTS).
The station will send an RTS to the RLM, that will include information
about the length of the frame that the station would like to transmit (see
Figure 25Medium Reservation “Request to Send”).
Upon receipt, the Access Point RLM will respond with a CTS message
to all stations within its range to:
notify all other stations to defer transmissions for the time-frame of
the requested transmission.
