A part of the 802.11n standard (or draft-standard). It allows sending multiple frames per single access to the medium by combining frames together into one larger frame. It creates the larger frame by combining smaller frames with the same physical source and destination end points and traffic class (i.e. QoS) into one large frame with a common MAC header.

 Aggregation Frames : The Aggregation Frames is in the range of 2~64, default is 32. It

determines the number of frames combined on the new larger frame.

 Aggregation Size : The Aggregation Size is in the range of 1024~65535, default is

50000. It determines the size (in Bytes) of the larger frame.

and will be applied to all VAPs and WDS Link.

2.6 Configure Wireless Advanced Setup

The administrator can change the Slot Time, ACK Timeout, RTS threshold and fragmentation threshold settings for the system. Please click on Wireless -> Advanced Setup and follow the below setting.

 Slot Time : Slot time is in the range of 9~1489 and set in unit of microsecond. The default

value is 9 microsecond.

Slot time is the amount of time a device waits after a collision before retransmitting a packet. Reducing the slot time decreases the overall back-off, which increases throughput. Back-off, which is a multiple of the slot time, is the random length of time a station waits before sending a packet on the LAN. For a sender and receiver own right of the channel the shorter slot time help manage shorter wait time to re-tra n smit from collision because of hidden wireless clients or other causes. When collision sources can be removed sooner and other senders attempting to send are listening the channel(CSMA/CA) the owner of the channel should continue ownership and finish their transmission and release the channel. Then, following ownership of the channel will be sooner for the new pair due to shorter slot time. However, when long duration of existing collision sources and shorter slot time exist the owners might experience subsequent collisions. When adjustment to longer slot time can’ t improve per formance then RTS/CTS could supplement and help improve performance.

 ACK Timeout : ACK timeo ut is in t he range of 1~372 and set in unit of microsecond. The

default value is 64 microsecond. All data transmission in 802.11b/g request an “Acknowledgement” (ACK) send by receiving radio. The transmitter will resend the original packet if correspondent ACK failed to arrive within specific time interval, also refer to as “ACK Timeout”.

ACK Timeout is adjustable due to the fact that distance between two radio links may vary in different deployment. ACK Timeout makes significant influence in performance of long distance radio link. If ACK Timeout is set too short, transmitter will start to “Resend” packet before ACK is received, and throughput become low due to excessively high re-transmission.

ACK Timeout is best determined by distance between the radios, data rate of average environment. The Timeout value is calculated based on round-trip time of packet with a little tolerance, So, if experiencing re-transmissions or poor performance the ACK Timeout could be made longer to accommodate.

Slot Time and ACK Timeout settings are for long distance lin ks. It is impo rtant to tweak settings to achieve the optimal result based on requirement.

 Beacon Interval : Beacon Interval is in the range of 40~3500 and set in unit of millisecond.

The default value is 100 msec. Access Point (AP) in IEEE 802.11 will send out a special approximated 50-byte frame, called “Beacon”. Beacon is broadcast to all the stations, provides the basic information of AP such as SSID, channel, encryption keys, signal strength, time stamp, support data rate.

All the radio stations received beacon recognizes the existence of such AP, and may proceed next actions if the information from AP matches the requirement. Beacon is sent on a periodic basis, the time interval can be adjusted.

By increasing the beacon interval, you can reduce the number o f beacons a nd associated overhead, but that will likely delay the association and roaming process because stations scanning for available access points may miss the beacons. You can decrease the beacon interval, which increases the rate of beacons. This will make the association and roaming process very responsive; however, the network will incur additional overhead and throughput will go down.

 DTIM Interval : The DTIM interval is in the range of 1~255. The default is 1.

DTIM is defined as Delivery Traffic Indication Message. It is used to notify the wireless stations, which support power saving mode, when to wake up to receive multicast frame. DTIM is necessary and critical in wireless environment as a mechanism to fulfill power-saving synchronization.

a DTIM interval is a count of the number of beacon frames that must occur before the access point sends the buffered multicast frames. For instance, if DTIM Interval is set to 3, then the Wi-Fi clients will expect to receive a multicast frame after receiving three Beacon frame. The higher DTIM interval will help power saving and possibly decrease wireless throughput in multicast applications.

 RTS Threshold : TRTS Threshold is in the range of 1~2347 byte. The default is 2347 byte.

The main purpose of enabling RTS by chan ging RTS th reshold is to reduce possible colli sions due to hidden wireless clients. RTS in AP will be enabled automatically if the packet size is larger than the Threshold value. By default, RTS is disabled in a normal environment supports non-jumbo frames.

 Short Preamble : By default, it’s “Enable”. To Disable is to use Long 128-bit Preamble

Synchronization field. The preamble is used to signal "here is a train of data coming" to the receiver. The short preamble provides 72-bit Synchronization field to improve WLAN transmission efficiency with less overhead.

 IGMP Snooping : the process of listening to Internet Group Management Protocol (IGMP)

network traffic. The feature allows a network switch to listen in on the IGMP conversation between hosts and routers. By listening to these c onversations the switch maintains a map of which links need which IP multicast streams. Multicasts may be filtered from the links which do not need them and thus controls which ports receive specific multicast traffic.

 Greenfield : In wireless WLAN technology, greenfield mode is a feature of major components

of the 802.11n specification. The greenfield mode feature is designed to improve efficiency by eliminating support for 802.11b/g devices in an all draft-n network. In greenfield mode the network can be set to ignore all earlier standards.

Queue

Data

AP to Clients

Priority

Description

 WMM QoS : This affects traffic flowing from the access point to the client station.

Configuring QoS options consists of setting parameters on existing queues for different types of wireless traffic. You can configure different minimum and maximum wait times for the transmission of packets in each queue based on the requirements of the media being sent. Queues automatically provide minimum transmission delay for Voice, Video, multimedia, and mission critical applications, and rely on best-effort parameters for traditional IP data.

As an Example, time-sensitive Voice & Video, and multimedia are given effectively higher priority for transmission (lower wait times for channel access), while other applications and traditional IP data which are less time-sensitive but often mor e data-intensive are expected to tolerate longer wait times.

 AC Type：

Transmitted

AC_BK Background Low High throughput. Bulk data that requires maximum

throughput and is not time-sensitive is sent to this queue (FTP data, for example).

AC_BE Best Effort Medium Medium throughput and delay. Most traditional IP

data is sent to this queue.

AC_VI Video High Minimum delay. Time-sensitive video data is

automatically sent to this queue.

AC_VO Voice High Time-sensitive data like VoIP and streaming media

are automatically sent to this queue.

 CWmin：Minimum Contention Window. This parameter is input to the algorithm that

determines the initial random backoff wait time ("window") for retry of a transmission. The value specified here in the Minimum Contention Window is the upper limit (in milliseconds) of a range from which the initial random backoff wait time is determined.。

 CWmax：Maximum Contention Window. The value specified here in the Maximum

Contention Window is the upper limit (in milliseconds) for the doubling of the random backoff value. This doubling continues until either the data frame is sent or the Maximum Contention Window size is reached. Once the Maximum Contention Window size is reached, retries will continue until a maximum number of retries allowed is reached. Valid values for the "cwmax" are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value for "cwmax" must be higher than the value for "cwmin".。

 AIFS：The Arbitration Inter-Frame Spacing Number specifies a wait time (in milliseconds)

for data frames。

 TxOP Limit：Transmission Opportunity is an interval of time when a WME AP has the

right to initiate transmissions onto the wireless medium (WM). This value specifies (in milliseconds) the Transmission Opportunity (TXOP) for AP; that is, the interval of time when the WMM AP has the right to initiate transmissions on the wireless network.。

 ACM bit：Admission Control Mandatory, ACM only takes effect on AC_VI and AC_VO.

When you do not click Checkbox, it means that the ACM is controlled by the connecting AP. If you click Checkbox, it means that the Client is in charge。

 No ACK policy bit：Acknowledgment Policy, WMM defines two ACK policies: Normal

ACK and No AC K. Clic k “ Checkbox” indicates “No ACK”

When the no acknowledgement (No ACK) policy is used, the recipient does not acknowledge received packets during wireless packet exchange. This policy is suitable in the environment where communication quality is fine and interference is weak. While the No ACK policy helps improve transmission efficiency, it can cause increased packet loss when communication quality deteriorates. This is because when this policy is used, a sender does not retransmit packets that have not been received by the recipient. When the Normal ACK policy is used, the recipient acknowledges each received uncast packet.。
