Table 31. 802.11g Radio Advanced Parameter Descriptions (Continued)

Parameter	Description
Fragmentation Threshold	Specifies the largest data frame that can
	be transmitted without fragmentation.
	Range is 256 to 1600.
	On certain radios, the fragmentation does
	not occur unless the radio detects
	interference. Larger frame sizes can
	improve throughput on a reliable
	connection. Smaller frame sizes can
	improve throughput on a poor connection.
Antenna control*	Specifies whether the radio uses two
	antennas or one antenna:
	Two Antennas: The radio selects the
	antenna for transmission and reception
	based on best reception.
	One Antenna: The radio uses only one
	antenna for transmission and reception.
Mixed Mode	Optimizes the frame burst window length
Performance*	to optimize performance for specific
	clients. Gives more time to higher rate
	frames to maximize throughput in the
	presence of low rate clients. Range is 0 to
	2000.
	Optimized for 802.11g clients: 802.11g
	transmissions are maximized.
	Optimized for 802.11b clients: 802.11b
	transmissions are maximized.
	Optimize Mixed (802.11g and 802.11b):
	Allows an optimal mix of 802.11g and
	802.11b transmissions.
Enable Data Rate	Determines if you want the radio to drop to
Fallback	a slower data rate when it has trouble
	communicating with another radio.
