3. Performance Parameters and Bandwidth Controller

This chapter gives instructions for editing the wireless radio protocol parameters to optimize radio performance and changing the Bandwidth Controller. These procedures are the same for all the operational modes.

3.1. Link Performance Parameters and Features

The wireless radio performance parameters can be edited to optimize the radio performance. The radio protocol parameters are:

1.Fragment Length (between 256 and 2346)

2.RTS/CTS (between 256 and 2346)

3.RSSI Threshold (between -90 and -20)

4.Preamble settings: Long, Short or Dynamic

5.Radio Operating mode

6.Throughout Optimizer

	a) Show current value
	b) Change to a value within its range
	This setting determines the size at which packets are fragmented. If
	the frame that the access point is transmitting is larger than the
Fragment Length	threshold, it will trigger the fragmentation function.
	The use of fragmentation can increase the reliability of frame
	transmissions. Because smaller frames are being sent, collisions are
	much less likely to occur.
	Default value is 2346 bytes. The range of value is from 256 to 2346.

	b) Change 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 higher 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.
