Item	Description
dtime Period	Every nth beacon is a dtime period. After each DTIM beacon, the AP would
	send any broadcast or multicast packets that may have been queued for
	power-save devices.
Country Code	A two-digit country code. Country information might not be displayed if the
	country information element (IE) is not present in the beacon.
Channels	A list of supported channels (from the country IE).
Power Constraint	The amount of power by which the maximum transmit power should be
	reduced from the regulatory domain’s limit.
Power Limit	Maximum transmit power in dBm permitted for that channel.
Channel Utilization	The percentage of time, normalized to 255, in which the AP sensed the medium
	was busy, as indicated by the physical or virtual carrier sense (CS) mechanism.
Station Count	Data rates required by the AP at which the station must be capable of operating.
Admission Capacity	An unsigned integer that specifies the remaining amount of medium time
	available through explicit admission control, in units of 32 µs/s.
	If the value is 0, the AP does not support this information element and the
	capacity is unknown.
WMM Supported	Support for Wi-Fi multi-media extensions.
UAPSD Supported	Unscheduled Automatic Power Save Delivery is supported by the AP. May
	only be available if WMM is supported. This feature is critical to talk time and
	achieving maximum call density on the wireless IP phone.
Proxy ARP	CCX compliant AP supports responding to IP ARP requests on behalf of the
	associated station. This feature is critical to standby time on the wireless IP
	phone.
CCX Version	Version of CCX if the AP is CCX compliant.
