negotiate the sending of a data frame. After receiving an RTS frame, the station
sends a CTS (clear to send) 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 will be enabled. The access points
contending for the medium may not be aware of each other.
◆ Fragmentation Threshold – Configures the minimum packet size that can be
fragmented when passing through the access point. Fragmentation of the PDUs
(Package Data Unit) can increase the reliability of transmissions because it
increases the probability of a successful transmission due to smaller frame size. If
there is significant interference present, or collisions due to high network utilization,
try setting the fragment size to send smaller fragments. This will speed up the
retransmission of smaller frames. However, it is more efficient to set the fragment
size larger if very little or no interference is present because it requires overhead to
send multiple frames.
