Status Menu
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.
