RTS/CTS Threshold (2.4 GHz radio only) — Sets the packet size threshold at
which a Request to Send (RTS) frame must be sent to a receiving station prior to
the sending station starting communications. The access point sends CTS (clear
to send) frames to a receiving station to negotiate the sending of a data frame.
After receiving an RTS frame, the access point sends a CTS frame to notify the
sending station that it can start sending data.
If the RTS threshold is set to 0, the access point always sends RTS signals. If set
to 2347, the access point never sends RTS signals. If set to any other value, and
the packet size equals or exceeds the RTS threshold, the RTS/CTS (Request to
Send / Clear to Send) mechanism is enabled.
The access points contending for the medium may not be aware of each other.
The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Range: 0-2347
