Parameter	Description
Power Output Level*	Set the transmitted power level:
	Maximum (63 mW): Sets the output power
	to the highest level supported by the radio.
	Medium (32 mW): Sets the output power to
	3 dB lower than the highest level
	supported by the radio.
	Low (16 mW): Sets the output power to a
	level higher than the minimum level
	supported by the radio.
	Minimum (2 mW): Sets the output power to
	the lowest level supported by the radio.
	Lowering the power output level reduces
	the radio coverage for this area and
	reduces the range for this radio.
Enable Medium	Determines if you want to set a reservation
Reservation	threshold.
	Check this check box to set a threshold
	value. Click Submit Changes, and the
	Reservation Threshold parameter
	appears.
	If you clear this check box, you may
	improve network response time in
	installations that usually send very small
	frames or that have no hidden stations.
Reservation Threshold	Appears only if the Enable Medium
	Reservation parameter is checked.
	If you enable medium reservation, you
	need to set a threshold value, which is the
	largest data frame that can be transmitted
	without reserving air time. Air time is
	normally reserved to help prevent
	collisions with other transmitters.
