The options are 20MHz / 10MHz / 5MHz. Different bandwidth has different throughput. Below is the list. Bandwidth Throughput 5MHz 5.5Mbps 10MHz 10Mbps 20MHz 20Mbps 19 VQOS / TDM: Versatile Quality of Service / Time-Division Multiplexing technique. TDM tech can avoid the packets collision and send the packets with more efficient way. You can set the data rate fractional (nx64 Kbps). This function is only available in CPE to Base station mode. Antenna: Please set to “Fixed on primary” Regatta mode: To shorten the header length of the fragmentation, enable this mode may make the throughput Advanced Parameters RTS Threshold: RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. If the size of the packet transmitted is larger than the value you set, the RTS will be enabled. When the RTS is activated, the Wireless Bridge will use a (RTS/CTS) mechanism for data transmission. The setting range is 0-2346. Fragmentation Length: Fragmentation mechanism is used for improving the efficiency when there is high traffic within the wireless network. If you transmit large files in a wireless network, you can enable the Fragmentation Threshold and specify the packet size. This specifies the maximum size a data packet will be before splitting and creating a new packet. The setting range is 256-2346. For example: If you set value as 256, it means the packet will be fragmented into “256” bytes while transmitting. Beacon Interval: This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the outdoor radio to keep the network synchronized. A beacon includes the wireless LAN service area, the outdoor radio address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). Space In Meter: This is used for extending ACK time-out destination. The setting range is 0-10000 m. The longer is the distance, the lower the throughput. Note: please set the value in this field according to the true distance, the value you set will affect the performance of the throughput. Our default value is 1000m. Time Slice: set the time slice of the VQOS / TDM. Wireless Setup / Peer-to-Peer Links 20 Configure a Wireless Point-to-Point Bridge To activate the Point-to-Point Bridge mode please do the following: 1. Configure both radio1 on LAN Segment A and radio2 on LAN Segment B in Point-to-Point Bridge mode. 2. Enter the MAC address of radio2 into the “Remote MAC Address” field of radio1. 3.

Configure a Wireless Point to Multi-Point Bridge There are two options under this setting: I. Point to Multi-point Bridge: Assume radio1 is the base station, radio2 and radio3 are clients. To activate the Multi-Point to Multi-Point Bridge mode please do the following: II. 1. Configure radio1, radio2, and radio3 in Point-to Multi-Point Bridge mode. 2. Verify that radio1 on LAN Segment A with the Remote MAC Address of radio2 and radio3. 3. Verify that radio2 on LAN Segment B with the Remote MAC Address of radio1. 4. Verify that radio3 on LAN Segment C with the Remote MAC Address of radio1. Multi-point to multi-point Bridge: To activate the Multi-Point to Multi-Point Bridge mode please do the following: 1. Configure radio1, radio2, and radio3 in Point-to Multi-Point Bridge mode. 21 2. Verify that radio1 on LAN Segment A with the Remote MAC Address of radio2 and radio3. 3. Verify that radio2 on LAN Segment B with the Remote MAC Address of radio1 and radio3. 4. Verify that radio3 on LAN Segment C with the Remote MAC Address of radio1 and radio2. After you complete the settings, please click on “Apply” for changes to take effect. Note: Under Point-to Multi-Point Bridge mode, you can extend this multi-point bridge by adding additional Wireless Bridges for each additional LAN Segment. Throughput control: you can set the throughput to n*64Kbps in each point. VAP / VLAN Settings As the number of data-based systems increase, it becomes more and more difficult to provide the network infrastructure (due to the sheer number of Ethernet connections that need to be provided) from the perspective of cost, space, and wire management. Luckily, the advent technology called VLAN (Virtual Local Area Network) can achieve her mission. Now it is possible for these multi devices in function without the need for multiple physical network APs. See the diagram below. Under this mode, this radio can behave as 8 virtual Wireless LAN infrastructures. You can specify unique SSID for these different infrastructures. For example, VLAN1 contains ETH1 and STA1, VLAN2 contains ETH2 and STA2, and so on. However, they all share 22 the same AP and undertake different tasks. Some VLANs can be used for guest Internet access, others for enterprise users, and administrators can be put on a high security VLAN with enhanced firewall permissions. All this can be achieved using a single infrastructure to emulate up to 8 infrastructures. The AP does this by assigning each of the 8 VLANs it’s own SSID, so you will think you are looking at up to 8different wireless networks. Enable this function to let associated clients be able to separate from each other when security is required. The default setting is Disable. Note: If you complete the settings, please click on “Apply” for changes to take effect. Wireless Setup / Encryption Settings To prevent unauthorized radios from accessing data transmitted over the link, the Encryption Settings window offers WEP features, making your data transmission over air more secure and allows you to specify Encryption Key(s) if you enable encryption for the Wireless Bridge. There are three degrees of encryption could be selected: 64 bits WEP, 128 bits WEP and 152 bits WEP. Also you can select WPA-PSK and WPA2-PSK for the advance security. 23 The following elaborate WEP/WPA security options. Field Description Network You have two authentication options. Authentication • Open System: No authentication is imposed to the radio. However, if the 802.1x option is configured, authentication of connections can be performed by a RADIUS server. • Shared: this is for shared key authentication. Data is encrypted. 24 Encryption You can select the following data encryption options: Disabled Strength 64- 128- or 152-bit WEP With Open System Authentication and 64128- or 152-bit WEP Data Encryption with Shared Key authentication Security WEP enabled, you can manually enter the four data encryption Encryption (WEP) keys or enable Passphrase to generate the keys automatically. Keys These values must be matched between all Clients and access points at your LAN (key 1 must be the same for all, key 2 must be the same for all, etc.) Two ways to create WEP encryption keys: • Passphrase. Passphrase functions as automatically case-sensitive characters. However, not all wireless adapters support passphrase key generation. • Manual. These values are not case sensitive. 64-bit WEP: enter 10 hexadecimal digits (any combination of 0-9, a-f, or A-F). 128-bit WEP: enter 26 hexadecimal digits (any combination of 0-9, a-f, or A-F). 152-bit WEP: enter 32 hexadecimal digits (any combination of 0-9, a-f, or A-F). WPA-PSK (Wi-Fi WPA Pre-Shared-Key uses a pre-shared key to perform the Protected Access authentication and generate the initial data encryption keys. Then, it Pre-Shared Key) dynamically varies the encryption key. It uses Temporal Key Integrity Protocol (TKIP) for encryption keys. However not all wireless adapters support WPA. Furthermore, client software is required on the client. Windows XP and Windows 2000 with Service Pack 3 do include the client software that supports WPA. Nevertheless, the wireless adapter hardware and driver must also support WPA. WPA 2-PSK Identical to WPA-PSK with the exception of the way to encryption keys. WPA2-PSK uses Advanced Encryption Standard (AES) for encryption keys. WPA-PSK& WPA You may have the option of WPA-PSK associated with TKIP. 2-PSK Alternatively, you can select WPA2-PSK associated with AES. 25 Note: WPA-PSK (TKIP) & WPA2-PSK (AES) only works at Base station and CPE mode. 3-3 Status Status / Connections The connections page provides below information in different settings. Mode information Base Station Mode CPE ID, MAC Address, IP Address and Status CPE Mode SSID, Channel, Wireless Status and Signal level Connections Page in Base Station mode Connections Page in CPE mode Status / Statistics The Statistics screen provides various Ethernet and Wireless TX/RX packet statistics on the Wireless Bridge.

Management / Reboot The Reboot AP screen enables you to reboot your Wireless Bridge. If any changes are made and you want them to take effect, you need to reboot the Wireless Bridge. Select the “Yes” check box and click “Apply”. It will take you about 50 seconds to go through reboot. The Web-browser will not be accessible until the Wireless Bridge has finished its reboot process. 30 Hardware reset If your Web User Interface stops responding, ping the IP address of the radio to check whether “reply” is obtained, or unplug and then plug back in the power supply of the Wireless AP Access Point. This will reboot the Wireless AP Access Point. If you are still unable to communicate with the Web User Interface, screw off the screw next to the grounding stud. Then use a stick to press in and hold the RESET button for five to ten seconds. This will reset the Wireless AP Access Point to the factory default settings. If you applied any personal configuration settings, you will need to make the changes again. Below is the tool to revolve the screws and press the reset button for your reference: Tool to screw off the screw of reset button. 2 Button head socket cap screws are attached with the mounting kits for spares, 3 times the most to reuse each screw for ensure the water-proof function. 31 Appendix A: Trouble shooting This Appendix helps you to isolate and solve the problems with the 4.9GHz outdoor subscriber. Before you start troubleshooting, it is important that you have checked the details in the product user manual and QIG. In some cases, rebooting the unit clears the problem. If the radio still can’t work well, please try to contact your local vendor or supplier. General Descriptions To successfully use the radios, engineers must be able to troubleshoot the system effectively. This section will show you how an 4.9GHz outdoor subscriber could be analyzed in the case of “no link,” usually, we thinks that the link is down because there is no traffic being passed. The four main reasons that a link may not work are list as below: Configuration Path issues (such as distance, obstacles, RF reflection…) Personal reasons (careless mounting or the incorrectly connection.) Hardware (includes the radio, cable and connectors…etc. In few cases, the radio will conflict with the laptop or PC) Environment (anything that is outside the equipment and not part of the path itself) After verified the correct configuration, double-checked the path terms, ensure no personal reasons and the hardware works well in the office, but the user still report that the link does not work. Most likely, the problem reported is caused by the environment or by improper tests to verify the connection. Assumes that the test method, cabling, antennas, and antenna alignment have been checked, (Always ensure this before checking the environment.) then you can do the follow to check the environment. General Check Two general checks are recommended before taking any action: Check whether the software version at both sides is the most current Check for any reported alarm messages in the Event Log Analyzing the Spectrum The best way to discover if there is a source of interference is to use the spectrum analyzer. By turning the antenna 360 degrees, you can find out which direction is the interference coming from. it will also show the frequencies and the level of signal is detected. Avoiding Interference When a source of interference is identified and when the level and frequencies are known, the next step is to avoid the interference. Some of the following actions can be tried: Change the RF channel to the one away from the interference source 32 50 802.11a Outdoor Multi-function Radio User Manual Change the polarization of the antenna; try to change to a polarization different from the interferer. A small beam antenna may helps. (Such as some grid or dish antenna, align the antenna in to the particular direction will reduce the affects from the interference source) This solution cannot help when the source of interference is right behind the remote site. Before checking for interference, ensure all the hardware works well and configurations are correct. The path analysis, cabling and antennas should be checked as well. Connection Issues This section describes several common troubles the customer might have while setting the radios. Radio Does Not Boot When the Radio does not Boot, do the following steps to check your whole system: 1. Ensure that the power supply is properly working and correctly connected. 2. Ensure that all cables are workable and connected correctly. 3. Check the power source. Cannot use the Web Interface If the radio boot, but can’t enter it via the Web site. 1. Open a command prompt window and enter ping(for example: ping 192.168.1.1). If there is no response from the radio, make sure that you the IP address is correct. If there is response, the Ethernet connection is working properly, do the next step. 2. Make sure that you are using one of the following Web browsers: Microsoft Internet Explorer version 5.0 or later Netscape version 5.0 or later. 3. Ensure that you are not using a proxy server for the connection with your Web browser. Double-check the physical network connections (includes the cables and the connectors). Use a well-known unit to ensure the network connection is properly functioning. Configuration Issues The following problems relate to setup and configuration problems. Some basic configurations might make the link fail, below are the major ones: RF Channel SSID IP address Rule of MAC address filter Rule of security settings (such as WEP or WPA) 33 Rule of authentication (such as settings of radius server and 802.1x) Configurations of WDS page If the links of the two radios works within close distance of each other, then there are two possible reasons why wireless connectivity is not possible while the 4.9GHz outdoor subscribers are at their desired locations: RF path, for example, a bad antenna alignment, the tower is not tall enough when the radios are installed in a long distance or the connector do not attachment well…etc (these are the most common problems in installations) Interference problem caused by a high signal level from another unit. The interference can be checked by changing the frequency and then see if another channel works better. Or you can change the polarization of the antenna as a way of avoiding the interfering signal. To know in advance how much interference is present in a given environment, a Spectrum Analyzer can be attached to a (temporary) antenna for measuring the signal levels on all available Channels. If the link still not works after resetting the configurations, checking the connectors and cables, double-check the path and environment issues, then the problem is possible a hardware problem. Acquiring a third radio and then testing it amongst the existing units will help to find out the broken unit. Please contact your local vendor for advance technical support. 34
