Default value is 2346 bytes. The range of value is from 256 to 2346.

 

 

 

 

 

 

 

 

a) Shows current value

 

 

 

 

b) Changes value

 

 

 

 

RTS: Request To Send

CTS: Clear To Send

 

 

 

The RTS/CTS length determines the packet size at or larger than the

 

RTS/CTS Length

 

set value. The radio issues a request to send (RTS) before sending

 

 

the packet.

 

 

 

 

 

 

 

 

The primary reason for implementing RTS/CTS is to minimize

 

 

 

collisions among hidden stations.

 

 

 

 

Default value is 2346 bytes. The range of value is from 256 to 2346.

 

 

 

 

 

 

 

This function provides better performance in high noise area. The

 

RSSI Threshold

 

device will ignore any signal below the set RSSI threshold.

 

 

 

 

 

 

 

The default value is -90. The value ranges from -90 to -20.

 

 

 

 

 

 

 

 

a) Shows current value

 

 

 

 

b) Chooses other settings available in the dropdown menu

 

 

 

The radio preamble is a section of data at the head of a packet that

 

 

 

contains information the Root Device and Remote devices need

 

 

 

when sending and receiving packets.

 

 

 

 

The dropdown menu allows the user to select a long, short or

 

Preamble Settings

 

dynamic radio preamble. The default is dynamic.

 

 

 

 

 

 

 

Long: a long preamble provides a stable link

 

 

 

Short: a short preamble improves throughput performance. But it only

 

 

 

allows short preamble capable Remotes to be associated.

 

 

 

Dynamic: a dynamic preamble allows mixing of short and long

 

 

 

preambles

 

 

 

 

 

 

 

 

The appropriate distance between the Root and the Remote devices

 

Distance

 

needs to be configured for best results.

 

 

The range of the link, which corresponds to the ACK window size.

 

 

 

 

 

 

 

 

 

 

Short 802.11g packets can be unwrapped and rebundled into a larger

 

 

 

packet to reduce the impact of mandatory gaps between the packets.

 

Frame Bursting

 

This increases the speed of the 802.11g based wireless networks.

 

 

 

 

 

 

Frame bursting is sometimes also called “packet bursting”.

 

 

 

 

 

 

 

The benefit of concatenation is that it increases the throughput by

 

Concatenation

 

removing overheads from “extra” frames and interframe latencies.

 

 

 

 

 

 

 

Piggy Back is a performance boosting feature which increases the

 

Piggy Back

 

effective transmission speed with no intervention.
