User’s Manual
500mW eXtreme Power 11Na Outdoor Bridge
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.
Extra Slot Time : Slot time is in the range of 1~255 and set in unit of microsecond. The default value is 9
microsecond.
34
User’s Manual
500mW eXtreme Power 11Na Outdoor Bridge
When you enable Short Slot and set Extra Slot time to “10”, the actual Slot Time=9+10 us.
When you disable Short Slot and set Extra Slot time to “10”, the actual Slot Time=20+10 us.
ACK Timeout : ACK timeout is in the range of 1~255 and set in unit of microsecond. The default value is 32
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 throughputs 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 links. It is important to tweak settings to achieve the
optimal result based on requirement.
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.
35
User’s Manual
500mW eXtreme Power 11Na Outdoor Bridge
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 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
36

500mW eXtreme Power 11Na Outdoor Bridge
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.
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 (DFS) : By default, it's “Disable”. To Enable is to use IEEE802.11H(DFS)
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
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.
The Channel 52-140 is DFS channel. If tuen on IEEE802.11H, AP Will have 60 sec to do channel available
check, and will not send beacon and can not be connect. When OW-200N2 detect radar(5GHz) signal, the AP
will switch channel and stop beacon trasmit between 15 sec.

When the no acknowledgment (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.

Ping Watchdog : The ping watchdog sets the OW-200N2 Device to continuously ping a user defined IP address
(it can be the internet gateway for example). If it is unable to ping under the user defined constraints, the
OW-200N2 device will automatically reboot. This option creates a kind of "fail-proof" mechanism.
Ping Watchdog is dedicated for continuous monitoring of the particular connection to remote
host using the Ping tool. The Ping works by sending ICMP “echo request” packets to the target
host and listening for ICMP “echo response” replies. If the defined number of replies is not
received, the tool reboots the device.

Watchdog Tool. The value of Startup Delay should be at least 60 seconds as the network interface and
wireless connection initialization takes considerable amount of time if the device is rebooted. Default is 300
seconds.
Î Failure Count To Reboot : specify the number of ICMP “echo response” replies. If the specified number of
ICMP “echo response” packets is not received continuously, the Ping Watchdog Tool will reboot the device.

2.5.4 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
time-critical 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.

class for DSCP.
9 BE : Default PHB, which is typically best-effort traffic
9 EF : Expedited Forwarding PHB, dedicated to low-loss, low-latency traffic
9 AF : Assured 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)

91
User’s Manual
500mW eXtreme Power 11Na Outdoor Bridge
3.5.1 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.
3.5.2 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
92
User’s Manual
500mW eXtreme Power 11Na Outdoor Bridge
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.
3.5.3 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.
3.5.4 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.
3.5.5 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.
3.5.6 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
93
User’s Manual
500mW eXtreme Power 11Na Outdoor Bridge
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.
3.5.7 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.
3.5.8 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.
3.5.9 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.
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.
DFS Channels

3.5.10 WMM : By default, it's “Disable”. To Enable is to use WMM and the WMM

Notice: When you enable WMM, the “Tx Burst” will be Disabled automatically by
system.
3.5.11 WMM Parameters of Access Point : 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 more
data-intensive are expected to tolerate longer wait times.

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
