Wireless Client Statistics
The traffic screen provides an overview of client traffic utilization. This screen also displays a RF quality index.
To view the traffic statistics of a wireless clients:

field displays the following:
Displays whether high throughput is supported. High throughput is a measure
of the successful packet delivery over a communication channel.
Displays whether this feature is supported. RIFS is a required 802.11n feature
that improves performance by reducing the amount of dead time between
OFDM transmissions.
Displays whether APSD is supported. APSD defines an unscheduled service
period, which is a contiguous period of time during which the access point is
expected to be awake.
Displays the Association ID established by an AP. 802.11 association enables
the access point to allocate resources and synchronize with a radio NIC. An
NIC begins the association process by sending an association request to an
access point. This association request is sent as a frame. This frame carries
information about the NIC and the SSID of the network it wishes to associate.
After receiving the request, the access point considers associating with the
NIC, and reserves memory space for establishing an AID for the NIC.
Displays the maximum size of AMSDU. AMSDU is a set of Ethernet frames to
the same destination that are wrapped in a 802.11n frame. This values is the
maximum AMSDU frame size in bytes.
Displays the maximum size of AMPDU. AMPDU is a set of Ethernet frames to
the same destination that are wrapped in an 802.11n MAC header. AMPDUs
are used in a very noisy environment to provide reliable packet transmission.
This value is the maximum AMPDU size in bytes.
Displays the time interval between two consecutive Ethernet frames.
Displays the guard interval in micro seconds. Guard intervals prevent
interference between data transmissions.
