13 - 184 WiNG 5.7.1 Access Point System Reference Guide
The
802.11 Protocol
field displays the following:
13.4.3 Traffic
The traffic screen provides an overview of client traffic utilization in both the transmit and receive directions. This screen also
displays a RF quality index.
To view the traffic statistics of a wireless clients:
Radio Number
Displays the access point radio the wireless client is connected to.
Radio Type
Displays the radio type. The radio can be 802.11b, 802.11bg, 802.11bgn, 802.11a or 802.11an.
Rate
Displays the permitted data rate for access point and client interoperation.
High-Throughput
Displays whether high throughput is supported. High throughput is a measure of the
successful packet delivery over a communication channel.
RIFS
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.
Unscheduled APSD
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.
Negotiated Fast BSS
Transition
Lists whether Fast BSS transition is negotiated. This indicates support for a seamless fast and
secure client handoff between two access points.
AID
Displays the
Association ID
(AID) established by an AP. 802.11 association enables the access
point to allocate resources and synchronize with a client. A client 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 client and the SSID of the network it
wishes to associate. After receiving the request, the access point considers associating with
the client, and reserves memory space for establishing an AID for the client.
Max AMSDU Size
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.
Max AMPDU Size
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.
Interframe Spacing
Displays the interval between two consecutive Ethernet frames.
Short Guard Interval
Displays the guard interval in micro seconds. Guard intervals prevent interference between
data transmissions. The guard interval is the space between characters being transmitted. The
guard interval eliminates
inter-symbol interference
(ISI). ISI occurs when echoes or reflections
from one character interfere with another character. Adding time between transmissions
allows echo's and reflections to settle before the next character is transmitted. A shorter
guard interval results in shorter character times which reduces overhead and increases data
rates by up to 10%.
