setting.

15
Advanced
The screen shows the advanced setting of the Wireless LAN Monitor
Utility, and it includes Preamble Type, Fragmentation Threshold, and
RTS / CTS Threshold. The default setting of Preamble Type is Long.
The usage of the preamble is to limit the packet size of the data to
transmit. It is recommended to choose the short preamble when the
link quality is bad, it is to prevent the wasting time of resending a long
packet that is lost.
Fragmentation Threshold is a way of transmitting the packets that will
be fragmented. Choose a setting within a range of 256 to 2346 bytes.
It is recommended to fragment the packet when the link quality is bad,
it is to prevent the wasting time of resending a long packet that is lost.
The RTS/CTS Threshold is a station initiates the process by sending a
RTS frame, the other ends receives the RTS and responds with a CTS
frame, the station must receive a CTS frame before sending the data
frame. This is to prevent the collisions by each station. Choose a
setting within a range of 1 to 1247 bytes. It is recommend to limit a
long packet to prevent each station
waiting too long to transmit a data.
