㻤Product BenefitThe 14dBi High Power Wireless N Outdoor PoE Access Point is the point of connection to Wireless Outdoor Network for service provider deploying last mile services to business or residential broadband subscribers.. Network administrators can create multiple subscriber service tier using per-subscriber rate limiting features, and manage centrally. WCB1200H2PX outdoor bridge utilizes a 200mW output Tx Power to connect to the WiFi mesh or WDS infrastructure and provides the subscriber with an Ethernet connection for a local access. The 14dBi High Power Wireless N Outdoor PoE Access Point can be used for nine different purposes in six different modes, the Router AP mode , AP mode, the WDS mode, the CPE mode, Client Bridge + Universal Repeater mode and CPE + AP mode, Installation ConsiderationsThere are a number of factors that can impact the range of wireless devices.1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at an angle. The more material the signal has to pass through the more signal you will lose.2. Keep the number of obstructions to a minimum. Each obstruction can reduce the range of a wireless device. Position the wireless devices in a manner that will minimize the amount of obstructions between them.3. Building materials can have a large impact on your wireless signal. In an indoor environment, try to position the wireless devices so that the signal passes through less dense material such as dry wall. Dense materials like metal, solid wood, glass or even furniture may block or degrade the signal.4. Antenna orientation can also have a large impact on your wireless signal. Use the wireless adapter’s site survey tool to determine the best antenna orientation for your wireless devices.5. Interference from devices that produce RF (radio frequency) noise can also impact your signal. Position your wireless devices away from anything that generates RF noise, such as microwaves, radios and baby monitors. 6. Any device operating on the 2.4GHz frequency will cause interference. Devices such as 2.4GHz cordless phones or other wireless remotes operating on the 2.4GHz frequency can potentially drop the wireless signal. Although the phone may not be in use, the base can still transmit wireless signal. Move the phone’s base station as far away as possible from your wireless devices. If you are still experiencing low or no signal consider repositioning the wireless devices or installing additional access points. The use of higher gain antennas may also provide the necessary coverage depending on the environment.

㻝㻡Wireless Advanced SetupTo 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.Short Slot : By default, it’s “Enable”for educing the slot time from the standard 20 microseconds to the 9microsecond short slot timeSlot 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 9microsecond.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.

㻝㻢ACK Timeout : ACK timeout is in the range of 1~255 and set in unit of microsecond. The default value is 32microsecond. 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 longdistance 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, datarate 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 100msec. 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 mechanismto 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.

㻝㻣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, RTSis 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.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 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 136, 140The 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 WCB1200H2PX detect radar(5GHz) signal, the AP will switch channel and stop beacon trasmit between 15 sec.

㻝㻤WMM : By default, it's “Disable”. To Enable is to use WMM and the WMM parameters should appears.When you enable WMM, the “Tx Burst” will be Disabled automatically by system.ÎWMM Parameters of Access Point : This affects traffic flowing from the access point to the client stationQueue Data TransmittedAP to Clients Priority DescriptionAC_BK Background. LowHigh 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 MediumMedium throughput and delay. Most traditional IP data is sent to this queueAC_VIVideo High Minimum delay. Time-sensitive video data is automatically sent to this queueAC_VOVoice HighTime-sensitive data like VoIP and streaming media are automatically sent to this queueConfiguring 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.

㻝㻥9Aifsn : The Arbitration Inter-Frame Spacing Number specifies a wait time (in milliseconds) for data frames9CWmin : Minimum Contention Window. This parameter is input to the algorithm that determines the initial random back-off wait time ("window") for retry of a transmission. The value specified here in the Minimum Contention Window is the upper limit (in milliseconds) of arange from which the initial random back-off wait time is determined.9CWmax: Maximum Contention Window. The value specified here in the Maximum Contention Window is the upper limit (in milliseconds) for the doubling of the random back-off 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".9Txop : 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.9ACM : 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.9AckPolicy : Acknowledgment Policy, WMM defines two ACK policies: Normal ACK and No ACK.Click “Checkbox” indicates “No ACK”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. ÎWMM Parameters of Station : This affects traffic flowing from the client station to the access point.Queue Data TransmittedClients to AP Priority DescriptionAC_BK Background. LowHigh throughput.

㻠㻥Wireless Advanced SetupTo 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.Short Slot : By default, it’s “Enable”for educing the slot time from the standard 20 microseconds to the 9microsecond short slot timeSlot time is the amount oftime 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 9microsecond.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.

㻡㻜ACK Timeout : ACK timeout is in the range of 1~255 and set in unit of microsecond. The default value is 32microsecond. 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 100msec. 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 thebuffered 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.

㻡㻝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. RTSin 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.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 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 136, 140The 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 WCB1200H2PX detect radar(5GHz) signal, the AP will switch channel and stop beacon trasmit between 15 sec.WMM : By default, it's “Disable”. To Enable is to use WMM and the WMM parameters should appears.

㻡㻞When you enable WMM, the “Tx Burst” will be Disabled automatically by system.ÎWMM Parameters of Access Point : This affects traffic flowing from the access point to the client stationQueue Data TransmittedAP to Clients Priority DescriptionAC_BK Background. LowHigh 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 MediumMedium throughput and delay. Most traditional IP data is sent to this queueAC_VIVideo High Minimum delay. Time-sensitive video data is automatically sent to this queueAC_VOVoice HighTime-sensitive data like VoIP and streaming media are automatically sent to this queueConfiguring 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.

㻡㻟9Aifsn : The Arbitration Inter-Frame Spacing Number specifies a wait time (in milliseconds) for data frames9CWmin : 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.9CWmax: 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".9Txop : 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.9ACM : 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.9AckPolicy : Acknowledgment Policy, WMM defines two ACK policies: Normal ACK and No ACK. Click “Checkbox” indicates “No ACK”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.

㻤㻜Configure Wireless Advanced SettingTo 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.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.Click Save button to save your changes. Click Reboot button to activate your changes.

㻝㻜㻟Resource SharingDMZDMZ is commonly work with the NAT functionality as an alternative of Virtual Server(Port Forwarding)while wanting all ports of DMZ host visible to Internet users. Virtual Server rules have precedence over the DMZ rule. In order to use a range of ports available to access to different internal hosts Virtual Server rules are needed.Please click on Advance -> DMZ and follow the below setting.DMZ : By default, it’s “Disable”. Check Enable radial button to enable DMZ.IP Address : Enter IP address of DMZ host and only one DMZ host is supported.Click Save button to save your changes. Click Reboot button to activate your changes. SSID: Main_AP192.168.2.ĲıInternetWIFI WAN192.168.1.254Main Base Station192.168.1.150LAN192.168.2.254NAT192.168.2.xDMZTEW-676APBO

㻝㻜㻠Virtual Server (Port Forwarding)“Virtual Server” can also referred to as “Port Forward” as well and used interchangeably. Resources in the network can be exposed to the Internet users in a controlled manner including on-line gaming, video conferencing or others via Virtual Server setup. Don’t repeat ports’ usage to avoid confusion.Suppose you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), and port 80 to another (B in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet.Please click on Advance -> Virtual Server and follow the below setting.Virtual Server : By Default, It’s “Disable”.Check Enable radial button to enable Virtual Server.Description : Enter appropriate message for resource sharing via Virtual Server.Private IP : Enter corresponding IP address of internal resource to share. Protocol Type : Select appropriate sessions, TCP or UDP, from shared host via multiple private ports.Private Port : A port or a range of ports may be specified as start:end; i.e. port 20:80Public Port : A port or a range of ports may be specified as start:end; i.e. port 20:80.The Private Port and Public Port can be different. However, total number of ports need to be the same.Example : Public Port is 11 to 20 and the Private Port can be a 10 ports range.Click “Add” button to add Virtual Server rule to List. Total of maximum20 rules are allowed in this List. All rules can be edited or removed from the List. Click Reboot button to activate your changes.

㻝㻜㻡While creating multiple Virtual Server rules, the prior rules have higher priority. The Virtual server rules have precedence over the DMZ one while both rules exist. Example 1 and 2 demonstrate proper usage of DMZ and Virtual Server rules.Example 1 : All connections should be redirected to 192.168.2.12 while DMZ is enabled. Since Virtual Server rules have precedence over the DMZ rule all connections to TCP port 22 will be directed to TCP port 22 of 192.168.2.10 and remaining connections to port TCP 20~80 will be redirected to port TCP 20~80 of 192.168.2.11DMZ Enabled : 192.168.2.12Rule Protocol Private IP Private Port Public Port1 TCP 192.168.2.10 22 222TCP 192.168.2.11 20:80 20:80Example 2 : All connections should be redirected to 192.168.2.12 while DMZ is enabled. Since Virtual Server rules have precedence over the DMZ rule all other connections to TCP port 20~80 will be redirected to port 20~80 of 192.168.2.11. The rule 2 won’t take effect.DMZ Enabled : 192.168.2.12Rule Protocol Private IP Private Port Public Port1 TCP 192.168.2.11 20:80 20:802TCP 192.168.2.10 22 22

㻝㻞㻝Access Point AssociationConfigure Wireless General SettingThe administrator can change the data transmission, channel and output power settings for the system. Please click on Wireless -> General Setup and follow the below setting.Band Mode : Select an appropriate wireless band; bands available are 801.11aor 802.11a/n mixed mode.Transmit Rate Control : Select the desired rate from the drop-down list; the options are auto or ranging from 6to 54Mbps for 802.11aCountry : Select the desired country code from the drop-down list; the options are US,ETSI,JP and NONE.Tx Power : You can adjust the output power of the system to get the appropriate coverage for your wireless network. Specify digit number between 1to 100 (the unit is %) for your environment. If you are not sure of which setting to choose, then keep the default setting, 100%.When Band Mode select in 802.11a only mode, the HT(High Throughput) Physical Mode and 11n Configurationsettings should be hidden immediately.Operating Mode : By default, it's Mixed Mode.ÎMixed Mode : In this mode packets are transmitted with a preamble compatible with the legacy 802.11a/g, the rest of the packet has a new format. In this mode the receiver shall be able to decode both the Mixed Mode packets and legacy packets.ÎGreen Field : In this mode high throughput packets are transmitted without a legacy compatible part.Channel Bandwidth : The "Auto” MHz option is usually best. The other option is available for special circumstances.Guard Interval : Using “Auto” option 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.

㻝㻞㻞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.

㻝㻞㻟Wireless Advanced SetupTo 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.Short Slot : By default, it’s “Enable”for educing the slot time from the standard 20 microseconds to the 9microsecond short slot timeSlot time is the amount of time a device waits after acollision 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 9microsecond.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.
