When Band Mode select in 802.11b/gn or 802.11n, the HT Physical Mode settings should be show immediately.

 Channel Bandwidth : The "20/40” MHz option is usually best. The other option is available for special

circumstances.

 Extension Channel : Only for Channel Bandwidth “40” MHz. Select the desired channel bonding for control.  MCS : This parameter represents transmission rate. By default (Auto) the fastest possible transmission rate will

be selected. You have the option of selecting the speed if necessary.

 Shout GI : Short Guard Interval, by default, it's “Enable”. it's can increase throughput. However, it can also

increase error rate in some installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for your installation.

 Aggregation : By default, it's “Enable”. To “Disable” to deactivated Aggregation.

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.

4.2.2 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-transmit 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 performance then RTS/CTS could supplement and help improve performance.

 ACK Timeout : ACK timeout is in the 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”.

Page 25

AP-952X Industrial Wall-mounted Wirele ss-N/BG AP/Bridge

User's Manual

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 retransmissions or poor performance the ACK Timeout could be made longer to accommodate.

Slot Time and ACK Timeout settings are for long distance links. It is important to tweak settings to achieve the optimal result based on requirement.

 RSSI Threshold : RSSI(Received Signal Strength Indication) Threshold is in the range of -127 ~ 128. The

default value is 24. RSSI Threshold can be used to control the level of noise received by the device.

 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 of beacons and 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.

 Fragment Threshold : The Fragment Threshold is in the range of 256~2346 byte. The default is 2346 byte.

Each Wi-Fi packet can be divided into smaller packets, marked with a sequential fragment number and reassemble in the receiving ends. The purpose is to make a short frame, instead of long frame, transmitting by radio in a heavy noisy environment. Because of sending smaller frames, corruptions are much less likely to occur. The pros is obvious, the cons is the overhead for transmission. So, in a clean environment, higher fragment threshold can be an option to increase throughput.

Fragmentation will be triggered by setting the Fragment Threshold, usually in Byte-length. Only when the frame size is over the Threshold, fragmentation will take place automatically.

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

The main purpose of enabling RTS by changing RTS threshold is to reduce possible collisions 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 72bit Synchronization field to improve WLAN transmission efficiency with less overhead.

 Tx Burst : By default, it’s “Enable”. To Disable is to deactivate Tx Burst.

With TX burst enabled, AP will send many packets in a burst, without collision detection and RTS/CTS for each packet. TX Burst have better throughput but cause interference with other APs in channel.

 802.11g Protection : Click Enable button to activate 802.11g Protection Mode, and Disable to inactivate

802.11g Protection Mode.

4.2.3 Create Virtual AP

The AP-952X support broadcasting multiple SSIDs, allowing the creation of Virtual Access Points, partitioning a single physical access point into 8 logical access points, each of which can have a different set of security, VLAN Tag(ID) and network settings. If wireless client connect to wired area network with VLAN Tag(ID), the administrator can use dump switch or VLAN switch on wired area network, a Figure 4-2 shows multiple SSIDs with different VLAN settings use dump switch connect to wired area. a Figure 4-3 shows multiple SSIDs with different VLAN settings use VLAN switch connect to wired area.
