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 three modes.

3.1. Link Performance Parameters and Features

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)Throughput Optimizer

	Page Item	Descriptions
		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 threshold, it will trigger the
	Fragment Length	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.
		The range of its value is from 256 to 2346. The default value is 2346 bytes.

		RTS: Request To Send	CTS: Clear To Send
	RTS/CTS Length	The RTS/CTS length determines the packet size at or larger than the 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
		the hidden stations.
		The range of its value is from 256 to 2346. The default value is 2346 bytes.
	RSSI Threshold	This function provides better performance in higher noise area. The device will
		ignore any signal below the set RSSI threshold.
		The default value is -90. The range of its value if from -90 to -20.
	Preamble Settings	a) Shows current value
		b) Choose other settings available from pull-down menu
		The radio preamble is a section of data at the head of a packet that contains
		information the airPoint™ Device and remote devices need when sending and
		receiving packets.
