3.2.2 Wireless Advanced Setup
To achieve optimal wireless performance, it is necessary to tweak advance setting per requirements properly, not
necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings for the system. Please click on
Wireless -> Advanced Setup and follow the below setting.
„
Beacon Interval : Beacon Interval is in the range of 20~1024 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 re-assemble
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
20
User Manual
WLO-15814N / WLO-15802N
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 72-bit
Synchronization field to improve WLAN transmission efficiency with less overhead.
„
Short Slot : By default, it’s “Enable” for educing the slot time from the standard 20 microseconds to the 9
microsecond short slot time
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.
„
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.
„
Pkt_Aggregate : By default, it's “Enable”
Increase efficiency by aggregating multiple packets of application data into a single transmission frame. In this way,
802.11n networks can send multiple data packets with the fixed overhead cost of just a single frame.
„
IEEE802.11H : By default, it's “Disable”. To Enable is to use IEEE802.11H
With DFS (Dynamic Frequency Selection) enabled, radio is operating on one of the following channels, the wireless
device uses DFS to monitor the operating frequency and switch to another frequency or reduce power as necessary:
DFS Channels
52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 136, 140
The maximum legal transmit power is greater for some 5 GHz channels than for others. When the wireless device
randomly selects a 5 GHz channel on which power is restricted, the wireless device automatically reduces transmit
power to comply with power limits for that channel in that regulatory domain.
„
WMM : By default, it's “Disable”. To Enable is to use WMM and the WMM parameters should appears.

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 timesensitive but often more data-intensive are expected to tolerate longer wait times.

AckPolicy : Acknowledgment Policy, WMM defines two ACK policies: Normal ACK and No ACK. Click
“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 unicast packet.

4.2.2 Advanced Setup
To achieve optimal wireless performance, it is necessary to tweak advance setting per requirements properly, not
necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings for the system. Please click on
Wireless -> Advanced Setup and follow the below setting.
„
Beacon Interval: Beacon Interval is in the range of 20~1024 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 re-assemble
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
53
User Manual
WLO-15814N / WLO-15802N
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 72-bit
Synchronization field to improve WLAN transmission efficiency with less overhead.
„
Short Slot : By default, it’s “Enable” for educing the slot time from the standard 20 microseconds to the 9
microsecond short slot time.
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.
„
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.
„
Pkt_Aggregate: By default, it's “Enable”
Increase efficiency by aggregating multiple packets of application data into a single transmission frame. In this way,
802.11n networks can send multiple data packets with the fixed overhead cost of just a single frame.
„
IEEE802.11H: By default, it's “Disable”. To Enable is to use IEEE802.11H
With DFS(Dynamic Frequency Selection) enabled, radio is operating on one of the following channels, the wireless
device uses DFS to monitor the operating frequency and switch to another frequency or reduce power as necessary:
DFS Channels
52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 136, 140
The maximum legal transmit power is greater for some 5 GHz channels than for others. When the wireless device
randomly selects a 5 GHz channel on which power is restricted, the wireless device automatically reduces transmit
power to comply with power limits for that channel in that regulatory domain.
„
WMM: By default, it's “Disable”. To Enable is to use WMM and the WMM parameters should appears.

AckPolicy: Acknowledgment Policy, WMM defines two ACK policies: Normal ACK and No ACK. Click
“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 unicast packet.

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

5.2.3 Create Wireless Profile
The administrator can configure station profiles via this page.
Please click on Wireless -> Wireless Profile and follow the below setting.
„
Profile Name : Set different profiles for quick connection uses.
„
ESSID : Assign Service Set ID for the wireless system.
„
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 re-assemble
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 : RTS 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 “Auto”. 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.
„
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.
„
WMM : By default, it's “Disable”. Select Enable, the packets with QoS WMM will have higher priority.
„
Security Type : Select an appropriate security type for association, the Security Type can be selected in “NONE”,
“OPEN”, “SHARED”, “WPA-PSK”, or “WPA2-PSK” from drop-down list; the type needs to be the same as that
associated access point.

5.4.3 QoS Setup
Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay, and the networking
methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the
network is congested. This can cause a reduction in network performance and make the network inadequate for timecritical application such as video-on-demand.
A classifier groups traffic into data flows according to specific criteria such as the source address, destination address,
source port number, destination port number or incoming port
number. For example, you can configure a classifier to
select traffic from the same protocol port (such as FTP) to form a flow.
„
Rules : Use the rules to define the classifiers. After you define the rules, you can specify action to act upon the traffic
that matches the rules.
Î
Comment : Enter a descriptive name for this rule for identifying purposes.
Î
MAC Address : Enter MAC address in valid MAC address format(xx:xx:xx:xx:xx:xx) and click “Add” button to
add in the MAC group of each rule. Click “Remove” button can remove MAC address in the group of each rule.
There are 10 MAC address maximum allowed in each rule.
Î
Source / Destination IP : Specify source/ destination IP addresses range required for this rule. If you specify
source IP addresses range from 192.168.1.1 to 192.168.2.254. The matches a range of source IP addresses
include every single IP address from the first to the last, so the example above includes everything from
192.168.1.1 to 192.168.2.254.
Î
DSCP Class : Differentiated services code point, DSCP. Select Any or specify classify traffic from drop-down list.
The Per-Hop Behavior (PHB) is indicated by encoding a 6-bit value—called the Differentiated Services Code
Point (DSCP)—into the 8-bit Differentiated Services (DS) field of the IP packet header. Below depicts class for
DSCP.
9
BE : Default PHB, which is typically best-effort traffic
100
User Manual
WLO-15814N / WLO-15802N
9
EF : Expedited Forwarding PHB, dedicated to low-loss, low-latency traffic
9
AF : Aaaured Forwarding PHB, which gives assurance of delivery under conditions. The AF behavior group
defines four separate AF classes. Within each class, packets are given a drop precedence (high, medium or
low). The combination of classes and drop precedence yields twelve separate DSCP encodings from AF11
through AF43 (see table)

6.2.2 Wireless Advanced Setup
To achieve optimal wireless performance, it is necessary to tweak advance setting per requirements properly, not
necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings for the system. Please click on
Wireless -> Advanced Setup and follow the below setting.
„
Beacon Interval: Beacon Interval is in the range of 20~1024 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 re-assemble
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
118
User Manual
WLO-15814N / WLO-15802N
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 72-bit
Synchronization field to improve WLAN transmission efficiency with less overhead.
„
Short Slot: By default, it’s “Enable” for educing the slot time from the standard 20 microseconds to the 9
microsecond short slot time.
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.
„
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.
„
Pkt_Aggregate: By default, it's “Enable”
Increase efficiency by aggregating multiple packets of application data into a single transmission frame. In this way,
802.11n networks can send multiple data packets with the fixed overhead cost of just a single frame.
„
IEEE802.11H: By default, it's “Disable”. To Enable is to use IEEE802.11H
With DFS(Dynamic Frequency Selection) enabled, radio is operating on one of the following channels, the wireless
device uses DFS to monitor the operating frequency and switch to another frequency or reduce power as necessary:
DFS Channels
52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 136, 140
The maximum legal transmit power is greater for some 5 GHz channels than for others. When the wireless device
randomly selects a 5 GHz channel on which power is restricted, the wireless device automatically reduces transmit
power to comply with power limits for that channel in that regulatory domain.
„
WMM: By default, it's “Disable”. To Enable is to use WMM and the WMM parameters should appears.

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 timesensitive but often more data-intensive are expected to tolerate longer wait times.

“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 unicast packet.
