Little or no modification of the Fragmentation Threshold value is
recommended as the default setting of 2346 is optimum for most
wireless networks.
RTS/CTS Threshold
Determines the packet size of a transmission and, through the use
of an access point, helps control traffic flow. The range is
0-2347bytes, or "off". The default value is 2347,which means that
RTS is disabled.RTS/CTS (Request to Send / Clear to Send) is the
mechanism used by the 802.11 wireless networking protocol to
reduce frame collisions introduced by the hidden terminal problem.
RTS/CTS packet size threshold is 0-2347 bytes. If the packet size
the node wants to transmit is larger than the threshold, the
RTS/CTS handshake gets triggered. If the packet size is equal to
or less than threshold the data frame gets sent
immediately.System uses Request to Send/Clear to Send frames
for the handshake which provide collision reduction for access
point with hidden stations. The stations are sending anRTS frame
first while data is sent only after handshake with an AP is
completed. Stations respond with the CTS frame to the RTS,
which provides clear media for the requesting station to send the
data. CTS collision control management has time interval defined
during which all the other stations hold off the transmission and
wait until the requesting station will finish transmission.
Label
Description
Mode
Selects whether the device is operating as anAccess Point (AP) or
a Station. Other options are Access Point WDS and Station WDS.
ESSID
Specifies the name or extended service set identifier (ESSID) of
the wireless network as it is provided in the beacon message. The
network namecan be up to 32 characters in length and
cancontainspaces. When running in AP mode, it is the name of the
network as advertised in the beacon message. In Station mode, it
is the network name that the station associates with.
