Advanced

The Advanced screen shows the advanced settings of the Wireless LAN Card Utility, and it includes Preamble Type, Fragmentation Threshold, and RTS / CTS Threshold.

Preamble Type:

The preamble is to limit the packet size of the data transmitted.

 

It is recommended that the short preamble is selected when the

 

link quality is bad, thereby preventing wasted time when

 

resending any lost packets. The default setting is Auto.

Fragmentation Threshold:

This option controls the way the transmitting packets will be

 

fragmented. If a packet is larger, in octets, than the threshold, the

 

packet will be split up, or fragmented, prior to being transmitted.

 

Once a packet is

 

fragmented, if a

 

portion of the

 

original packet is

 

corrupted in

 

transit, only the

 

corrupted portion

 

needs to be

 

retransmitted.

 

Throughput is

 

generally lower for

 

fragmented

 

packets, however,

 

because the packet

 

header consumes

 

RF bandwidth.

 

It is recommended

 

to fragment the packet when the link quality is bad, so as to

 

reduce the time taken to resend a lost packet.

RTS/CTS Threshold

Defines a threshold for the number of packets that can be

 

received before the NetComm NP7042 - Wireless LAN USB

 

Adaptor will issue a Request to Send (RTS) packet. The RTS

 

packet is used to avoid data collisions on the WLAN. There are

 

some trade-offs to consider when setting this parameter. A small

 

RTS threshold will cause RTS packets to be sent more often,

 

thereby consuming bandwidth and reducing the apparent

 

throughput of the WLAN. The more often RTS packets are sent,

 

however, the quicker the WLAN can recover from interference or

 

data collisions. Refer to the IEEE 802.11b standard for more

 

information on the RTS/CTS mechanism.
