Wireless Interface Commands

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.
Example
rts-threshold
This command sets the packet size threshold at which a Request to Send (RTS)
signal must be sent to the receiving station prior to the sending station starting
communications.
Syntax
rts-threshold <threshold>
threshold - Threshold packet size for which to send an RTS.
(Range:
0-2347 bytes)
Default Setting
2347
Command Mode
Interface Configuration (Wireless)
Command Usage
• If the 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 point sends RTS frames to a receiving station to negotiate the
sending of a data frame. After receiving an RTS frame, the station sends a
CTS frame to notify the sending station that it can start sending data.
• Access points contending for the wireless medium may not be aware of
each other. The RTS/CTS mechanism can solve this “Hidden Node”
problem.
