LABEL	DESCRIPTION
A-MPDU	This field is not available in the NWA1123-NI.
Aggregation	Select to enable A-MPDU aggregation.
	Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their
	802.11n headers and wraps them in a 802.11n MAC header. This method is useful for
	increasing bandwidth throughput in environments that are prone to high error rates.
Short GI	This field is not available in the NWA1123-NI.
	Select Enabled to use Short GI (Guard Interval). The guard interval is the gap introduced
	between data transmission from users in order to reduce interference. Reducing the GI
	increases data transfer rates but also increases interference. Increasing the GI reduces data
	transfer rates but also reduces interference.
