11-Mbps Wireless Outdoor Bridge 1 Introduction Congratulations on choosing an outstanding wireless product. This guide gives comprehensive instructions on installing and using the 11-Mbps Wireless Outdoor Bridge, and also explains how to install and use the WLAN Management System software.
11-Mbps Wireless Outdoor Bridge 2 Related Products 11-Mbps Wireless Outdoor Bridge is part of a family of wireless networking products that can provide an integrated solution for your wireless networking needs. • For indoor applications: Access points, wireless workgroup bridges, wireless Ethernet clients, and wireless adapters with various bus interfaces (PCMCIA, USB, and PCI). • For outdoor applications: The 11-Mbps Wireless Outdoor Bridge connects two independent Ethernet LANs via a radio link, making expensive outdoor cabling unnecessary. High-gain directional antennas provide the greatest possible transmission range. • Management tools: 11-Mbps wireless products support the industry-standard Simple Network Management Protocol (SNMP) and the SNMP-based WLAN Management System, a powerful set of utilities for managing not only devices but whole networks and inter-networks.
11-Mbps Wireless Outdoor Bridge 3 WLAN Management System WLAN Management System is a powerful network management system that is fully compatible with the industry-standard Simple Network Management Protocol (SNMP). It features: • Automatic discovery of all compatible devices that are configured within the same subnet. • Individual and batch-mode remote management of compatible devices, including Multi-Monitor, Batch-Upgrade, Batch-Reset, and Batch-Load Default functions. Batch-mode operation is ideal when deploying multiple compatible products. • A friendly end-user interface with a consistent look and feel. Automatic Discovery of Compatible Devices A powerful auto-discovery algorithm is built into WLAN Management System. With a simple click on the Auto Discovery icon, all compatible devices within the subnet will be discovered. This discovery feature is based on the following techniques: • DHCP client and IP recovery: The Outdoor Bridge has a built-in DHCP client, and will request an IP address from a DHCP server so that SNMP management can be carried out. Should there be a failure of the DHCP server, the Outdoor Bridge will auto-assign itself an IP address (see next) and then automatically negotiate for a new IP address when the server recovers. • Auto-IP: When the Outdoor Bridge cannot get an IP address from a DHCP server, it will auto-assign itself an IP address of 169.254.x.x and a subnet mask of 255.255.0.0. A Windows-based system configured as a DHCP client will use the same algorithm to assign itself an IP address in the same subnet. When the DHCP server comes back on line, users may need to renew their stations’ IP settings as described below; otherwise, Windows may continue to use the previous IP address instead of executing the auto-IP procedure.
11-Mbps Wireless Outdoor Bridge 4 Windows 95/98 step 1. Click Start/Run, type winipcfg, and click OK. The IP Configuration dialog box will open. step 2. Select the network adapter you use to connect to the Outdoor Bridge. Click Release. step 3.

Click Start/Programs/Command Prompt. Type ipconfig /release (with a space after ipconfig) and press Enter. step 2. Type ipconfig /renew (with a space after ipconfig) and press Enter to retrieve new information (IP address, subnet mask, and default gateway address) from the DHCP server. step 3. Type exit and press Enter. Windows 2000/XP step 1. Click Start/Programs/Accessories/Command Prompt. Type ipconfig /release (with a space after ipconfig) and press Enter. step 2. Type ipconfig /renew (with a space after ipconfig) and press Enter to retrieve new information (IP address, subnet mask, and default gateway address) from the DHCP server. step 3. Type exit and press Enter.
11-Mbps Wireless Outdoor Bridge 5 WLAN Management System Hardware and Software Requirements System requirements for installing and operating the WLAN Management System are: • An x86-based microcomputer running Microsoft Windows 95, 98, Me, NT 4.0, 2000, or XP • Microsoft Internet Explorer 4.01 or later • A connection to an Ethernet network Particular versions of Windows have the following additional requirements: 1. On Windows 95, Microsoft DCOM95 must be installed. You can obtain DCOM95 from the following Microsoft Web page: http://www.microsoft.com/com/dcom/dcom95/download.asp DCOM95 can also be found on the Microsoft Visual Basic 5.0 CD-ROM (Enterprise, Professional, or Standard edition), in the directory \Pro\Tools\DCOM95. 2. On Windows 98 (with the exception of Windows 98SE, which already includes this component), Microsoft DCOM98 must be installed. You can use the following link to download it: http://www.microsoft.com/com/dcom/dcom98/download.asp 3. On Windows NT 4.0, Service Pack 4 or later must be installed.
11-Mbps Wireless Outdoor Bridge 6 Terminology Used in this Guide BSSID, MAC ID The BSSID (Basic Service Set ID) is a factory-set ID unique to each wireless networking product. It is identical to the MAC ID (Media Access Control ID). It allows each device to be identified on the wireless network. ESSID An Extended Service Set ID (often referred to as Service Set ID, or SSID) identifies the wireless LAN domain that a bridge is in. A domain is generally composed of wireless bridges in communication with each other via radio links. You can type an existing domain name or create a new one that contains up to 32 characters. The SSID is case-sensitive. Regulatory Domain 11-Mbps wireless products use the license-free ISM (Industrial, Scientific, and Medical) band to communicate through radio waves. Different countries offer different radio frequencies to be used as the ISM band. There are four frequency bands defined by IEEE 802.11: Japan (2.471 to 2.497 GHz), USA, Extended Japan, Canada, and Europe (2.4 to 2.4835 GHz), Spain (2.445 to 2.475 GHz), and France (2.4465 to 2.4835 GHz). To use 11-Mbps wireless products in a country not listed above, check with your government’s regulating body to find the correct frequency band to use. All 11-Mbps wireless products are supplied preset to the country of sale’s frequency band. WEP WEP stands for Wired Equivalent Privacy. It is an encryption scheme that provides secure wireless data communications. WEP uses a 40-bit or 128-bit key to encrypt data. In order to decode the data transmission, all wireless clients on the network must use identical keys.
11-Mbps Wireless Outdoor Bridge 7 How to Use this Guide This user’s guide gives complete instructions for installation and use of the 11-Mbps Wireless Outdoor Bridge. Wireless Outdoor Bridge is supplied with factory set default network settings. Use the WLAN Management System tool to change the default settings before introducing a new bridge to an already-established wireless network. The WLAN Management System is a simple-to-use, yet extremely powerful, SNMP-based utility for online central configuration and network management from a remote station on the same subnet. A trap management program is also provided to monitor/diagnose the Outdoor Bridge. Read through the next section ‘Planning the Network’, in order to get the best possible performance from the 11-Mbps wireless network. Step 1: Plan the wireless network See “Planning the Network,” for details. Step 2: Pre-configure the bridge before installing it into an existing Ethernet network See “Hardware Configuration,” for details. Step 3: Install the bridge into the Ethernet network See “Installing the WLAN Management System,” for details. Step 4: Make online configuration and manage the bridge via the WLAN Management System utility See “Using the WLAN Management System,” for details.
11-Mbps Wireless Outdoor Bridge 8 Planning the Network The Wireless Outdoor Bridge is used to connect two separate networks via radio waves. A typical application is shown below. Figure 1. Typical application scenario The bridge connects to your existing wired or wired/wireless local area network as shown below (Figure 2). Figure 2. Connection to LAN or LAN/WLAN
11-Mbps Wireless Outdoor Bridge 9 Hardware Description Figure 3. Wireless Outdoor Bridge and DC injector
11-Mbps Wireless Outdoor Bridge 10 Hardware Configuration Before adding a Wireless Outdoor Bridge to an existing Ethernet network, you need to carry out basic configuration, e.g., set the SSID, security (WEP) parameters, bridge mode (including the peer bridge’s MAC address), channel number, and IP address in order to make the bridge compatible with the existing network. Figure 4. Wireless Outdoor Bridge Solution Installation
11-Mbps Wireless Outdoor Bridge 11 Pre-configuration can be carried out through WLAN Management System. As long as the outdoor bridge and the management station are on the same physical Ethernet LAN, WLAN Management System’s Kick Start function will find the outdoor bridge and let you set basic parameters. Make connections as follows: step 1. Using the supplied Category 5 waterproof cable, connect the waterproof connector port of the outdoor bridge to the ODU port of DC injector. step 2. Using Category 3 or higher UTP or STP cable, connect the RJ-45 port of DC injector to a 10- or 10/100-Mbps Ethernet hub or switch, and connect the management station to a hub or switch on the same LAN. step 3. Connect the output cord of the power adapter to the DC injector’s DC input jack, and plug power adapter into an AC outlet to power up the outdoor bridge (see Figure 4 and Figure 5). Figure 5. Wireless Outdoor Bridge Installation
11-Mbps Wireless Outdoor Bridge 12 11-Mbps Wireless Product Placement Guidelines A few tips to mention that are particularly significant in a radio wave communications system: 1. Radio waves reflect or refract from buildings, walls, metal furniture, or other objects. This could result in performance degradation due to the fluctuation of the received signal. 2. Microwave ovens use the 2.45 GHz frequency band. 11-Mbps wireless devices also functions in the 2.4 ~ 2.5 GHz band, and therefore shares some of the band with microwave ovens. This means that when a nearby microwave oven is in use, it may interfere with 11-Mbps wireless signals, resulting in performance degradation on the wireless network. Antenna Alignment For the best performance, adjust the position of the antenna until an optimal signal quality results (see Antenna Alignment Utility for details).
11-Mbps Wireless Outdoor Bridge 13 Installing the WLAN Management System step 1. Insert WLAN Management System Disk 1 in floppy drive A, choose Run from the desktop’s Start menu, type a:\setup.exe, and click OK. step 2.

11-Mbps Wireless Outdoor Bridge 18 Figure 12. WLAN Kick Start window This window’s Tools menu also lets you test IP connectivity, reboot, reset the selected device, or change its password. The administrator password set on the device is “admin” as the default. The Edit menu is for manually adding and removing devices in the display. The Start menu, in addition to letting you initiate Kick Start discovery, lets you set preferences for the Kick Start and ping functions (timeout periods, number of tries, etc.). Configuration step 1. For configuration, select the outdoor bridge in the Hosts View window. step 2. Right-click the outdoor bridge to open the pop-up menu (Figure 11). step 3. Click Config to go to the configuration window (Figure 13).
11-Mbps Wireless Outdoor Bridge 19 Figure 13. Configuration window — IP panel IP IP Address Setting: The outdoor bridge is a DHCP client. It will automatically ask the DHCP server to assign it an IP address. An administrator can assign a fixed IP to an outdoor bridge by unchecking the Obtain IP Settings Automatically (by DHCP) box (Figure 13). You may also configure a subnet mask and add a default gateway. If you assign a fixed IP address to an outdoor bridge, make sure that all outdoor bridges within the same network have the same TCP/IP subnet address. Obtain IP Settings Automatically (by DHCP) Automatically retrieves an IP address for the outdoor bridge from a Dynamic Host Configuration Protocol (DHCP) server. This option is enabled by default. IP Address Manually assigns an IP address to the outdoor bridge. Subnet Mask Manually assigns a subnet mask to the outdoor bridge. Default Gateway Manually specifies the default gateway IP address (if required). Note: An outdoor bridge will directly transfer SNMP response packets (confirmation packets) to a management PC if it is within the same LAN (the same subnet mask). If an SNMP response packet from an outdoor bridge is destined for a management PC on another LAN, the SNMP response packet needs to be forwarded by routers. The default gateway is the closest router to
11-Mbps Wireless Outdoor Bridge 20 the outdoor bridge. If the correct default gateway is set, you can use a manager (i.e. a PC running WLAN Management System) physically located in a different subnet to manage this outdoor bridge. Filter The next panel in the configuration dialog box is Filter (Figure 14). Figure 14. Configuration window — Filter panel This is a one-way protocol filtering mechanism that prevents the bridge from transmitting specified protocols packet from a wired Ethernet LAN into the wireless LAN. If you do not require particular protocols on the wireless part of your network, you can save bandwidth by enabling the protocol filter. From the Filter panel, some, all, or none of the protocols listed may be selected for filtering out: • IP Protocol • IPX Protocol • NetBEUI Protocol • AppleTalk Protocol • Other Protocols
11-Mbps Wireless Outdoor Bridge 21 • Internet Multicast Frames Wireless The Wireless panel (Figure 15) provides access to the Wireless settings. Figure 15. Configuration window — Wireless panel These settings are explained in the following table. Name Assigns the outdoor bridge a unique name that allows the outdoor bridge to be easily identified on the network. SSID Identifies the wireless domain that this outdoor bridge is in. A wireless domain, in the case of outdoor bridges, is ordinarily composed of two or more outdoor bridges that are in communication with each other via radio links. Wireless outdoor bridges that will be in communication with each other must be set to use the same SSID in order to be able to establish a wireless link or links. You can type an existing domain name or create a new one. An SSID is case-sensitive and can contain up to 32 characters. Transmission Rate Sets the transmission rate at which data packets are transmitted by the outdoor bridge. In high-interference environments, a lower rate can increase overall transmission speed by reducing resends of lost packets.
11-Mbps Wireless Outdoor Bridge 22 Basic Rates This value determines the basic rates used and reported by the outdoor bridge. The highest rate specified is the rate that the outdoor bridge will use when transmitting broadcast/multicast and management frames. Available options are: • 1, 2 Mbps • All (1, 2, 5.5, and 11) Mbps Channel Number You can change the channel number from here. Wireless outdoor bridges that will be in communication with each other must be set to use the same channel in order to be able to establish a wireless link or links. Regulatory Domain Identifies the country where the outdoor bridge is used. Each country has defined its available channel numbers and transmission power Important: In a multiple cell network topology, overlapping and/or adjacent cells using different channels can operate simultaneously without interference if the difference between the center frequencies is at least 30 MHz. For example, channels 1, 7, and 13 are non-overlapping frequency channels. Bridge Mode Figure 16. Bridge Mode – Point to Point
11-Mbps Wireless Outdoor Bridge 23 Point to Point Each bridge has to know its peer bridge’s MAC address. For example, if Bridge A is to connect with Bridge B, then Bridge B’s MAC address must be entered on this page for Bridge A, and Bridge A’s MAC address must be entered here for Bridge B. Figure 17. Bridge Mode – Point to Multipoint Point to Multipoint If a large wireless network using more than two outdoor bridges is to be constructed, at least one of the outdoor bridges must be set to Point-to-Multipoint mode. Other outdoor bridges can be set to either Point-to-Point or Point-to-Multipoint mode. In this mode, up to six other bridges can be connected. Their MAC addresses must be entered here. For example; if Bridge A is the master bridge and needs to connect with Bridge 1 and Bridge 2, then when setting Bridge A, the MAC addresses of Bridge 1 and Bridge 2 must be entered on the Bridge Mode page (Figure 17). Likewise, Bridge 1 and Bridge 2 must be set to Point to Point mode, and Bridge A’s MAC address must be entered as the peer bridge MAC address (Figure 16).
11-Mbps Wireless Outdoor Bridge 24 Encryption Click the Encryption tab (Figure 18) to set up the security options. Figure 18. Configuration window — Encryption panel The default setting is WEP Disabled and initially the key sections are blank. The pull-down Method box lists two options: • WEP: Disable - Disable data encryption • WEP: Enable - Enable data encryption If enabled data encryption, there are two options in the pull-down Key Length box: • 40-bit WEP - Enable use of 40-bit WEP • 128-bit WEP - Enable use of 128-bit WEP Key Generation - There are two ways to generate a security key. The first is by entering any text in the Passphrase field. Click the Generate button. For 40-bit WEP, it will generate four keys, Key 1, Key 2, Key 3, and Key 4. Select a key number from the dropdown list of the Default Key box. If you do not manually select a key, key 1 will be selected. For 128-bit WEP, only one key will be generated. Click OK.
11-Mbps Wireless Outdoor Bridge 25 Another WEP key generation method is to insert the key values directly from the keyboard. Enter your own key into one of the Key 1~4 fields. Select that field number in the Default Key field. SNMP Access Control The outdoor bridge contains an SNMP access table to limit access to its configurations. By default there is no restriction on accessing the outdoor bridge. To avoid chaos on the network, access to the outdoor bridge configuration should be restricted to only those who require access. When you select SNMP Access Control, the system will display four blank wireless devices for setting (maximum of 4 SNMP devices can be set). Right-click on a blank in the list and click Edit Address (Figure 19). Figure 19. Configuration window — SNMP Access Control panel The New/Edit Address dialog box will open (Figure 20). Figure 20. New/Edit Address dialog box

Antenna Alignment Utility The wireless bridge is usually used to connect two separate LANs via the radio link with a directional antenna to extend the distance between two wireless bridges. Sometimes the distance between two LANs might be several kilometers. Owing to the nature of the directional antenna, the higher the antenna gain is, the narrower the angle of the wave propagation will be. In order to achieve the best radio performance of wireless outdoor bridge, the antenna alignment utility is developed to help the technician in easily installing the antenna as well as achieving the best radio performance. Features The Antenna Alignment Utility features: • Integrated together within WLAN Management System • Easy to use • Real-time display of radio performance • Two-dimensional or three dimensional graphic presentation of test results • The historical test data and setup conditions can be stored and retrieved to compare with the latest test results. Using the Antenna Alignment Feature Step 1: Access the Antenna Alignment function After wireless outdoor bridge and the antenna have been successfully installed, antenna alignment can be carried out. Connect a notebook PC directly to an outdoor bridge. Start up WLAN Management System on the notebook PC. Click the Auto-discovery icon. The outdoor bridge connected to the notebook PC will be found and shown on the screen. Select the outdoor bridge and then click the right mouse button. The available tools for a wireless bridge will be shown. Then, select Antenna Alignment.
11-Mbps Wireless Outdoor Bridge 34 Figure 31. Antenna alignment for bridges Step 2: Set the parameters for testing The calculation of the antenna alignment is conducted by the following procedure: • Bridge A sends a packet to Bridge B • When Bridge B successfully receives the packet from Bridge A, it will automatically echo the packet back. • When Bridge A receives the packet echoed back by Bridge B, it can calculate the throughput and can present it as PPS (packets per second) and KBPS (kilobytes per second). The higher the throughput is, the better alignment is achieved. Since every installation is different (for example, the difference in distance, temperature, humidity, and alignment angle) no standard reference can be given. The user can specify the following parameters for each test: • Packet Length: Ranges from a minimum of 64 bytes to a maximum of 1514 bytes, as Ethernet does. The larger the packet size is, the higher the error rate is likely to be. • Packet Count: The packet number to be sent during the test. The larger the packet count is, the more time the test will take.
11-Mbps Wireless Outdoor Bridge 35 • Peer Bridge: In a Point to Multi-Point application environment, all the wireless bridges configured to communicate with each other are shown in the pull-down Peer Bridge box. A peer bridge has to be specified by indicating its MAC address before starting the antenna alignment test. The selected bridge must be set up to be able to communicate with the bridge initializing the alignment test. Figure 32. Antenna Alignment Tool Tips in setting the parameters: 1. Rough alignment: When the bridges are first set up, the antennas of the bridges are not yet aligned under an optimum condition. It is recommended to use a shorter size and a smaller packet count to perform the test so that test results can be obtained quickly. 2. Fine Alignment: Once the test reveals that the antenna is just about aligned, enter a longer packet size and larger packet count for the fine alignment. Step 3: Execute the test and evaluate the performance After all the parameters have been properly entered, click Start on the right side of the window to execute the test. Test results are immediately presented as a three-dimension graphic (Figure 33).
11-Mbps Wireless Outdoor Bridge 36 Figure 33. Throughput presented as a 3D graphic During the antenna alignment test, the bridge might receive interference owing to some unexpected reason. Under this circumstance, the wireless communication data rate will automatically fall back. The numbers of packets sent or received at different data rates can be viewed as shown below (Figure 34). Figure 34. 3D view of data rate distribution Step 4: Save the test results to a file The tests may be repeated as described in Step 3 until the antenna is aligned at the optimum position.

11-Mbps Wireless Outdoor Bridge 46 FAQs The FAQs section attempts to answer the most commonly asked questions about the 11-Mbps Wireless Outdoor Bridge. Question Answer How can I manage the bridge? The bridge does not have a console port. You may easily configure and manage the bridge remotely via its standard RJ-45 Ethernet network interface. Configure the bridge using the method described in this manual. Can wireless clients associate with the bridge? No, the bridge is a transparent bridge, NOT an access point. At what radio frequency does a bridge communicate? In the US, wireless LAN radios transmit and receive on one of 11 channels in the 2.4-GHz frequency band. This is a public frequency, and is unlicensed by the FCC. How do I secure the data crossing a bridge's radio link? Enable Wired Equivalency Protocol (WEP) to encrypt the payload of packets sent across a radio link. What is the typical range for a bridge? The typical range depends on many factors, including the following: data rate (bandwidth) desired, antenna type, antenna cable length, and device receiving the transmission. In an outdoor antenna installation, range can be up to 1.5 km or more. What is the speed of the bridge's Ethernet port? The bridge's Ethernet port supports 10 Mbps over a 10Base-T RJ-45 connector (half-duplex only). What are possible sources of interference for the radio frequency link of the bridge? Interference can come from a number of sources, including 2.4-GHz cordless phones, improperly shielded microwave ovens, and wireless equipment manufactured by other companies. Police radar, electrical motors, and moving metal parts of machinery can cause interference too.

In what modes can the bridge operate? The bridge can operate in Point-to-Point mode and Point-to-Multiple Point mode Do the antennas need line of sight to function? The antennas connecting to a bridge need not only visual line of sight, but also radio line of sight. Radio line of sight includes an elliptical region around the visual line of sight called the Fresnel zone. For optimal performance, make sure the Fresnel zone is clear of all obstructions including trees, power lines, buildings, and geographic obstacles.
11-Mbps Wireless Outdoor Bridge 48 Troubleshooting This section provides you with some troubleshooting info should you encounter installation or operation problems on 11-Mbps Wireless Outdoor Bridges. If the problems still cannot be remedied after going through the Troubleshooting section, check the FAQs on page 47 of this manual. If your problems still cannot be remedied after going through the FAQs and this Troubleshooting section, contact your network equipment supplier for assistance (see “Technical Support,” page 51). Symptom Suggested Solutions The WLAN Management System cannot detect an Outdoor Bridge on the same network. 1. Make sure the outdoor bridge is powered on and connected to an Ethernet work. 2. Check the IP addresses assigned to the outdoor bridge and management terminal PC. They should be in the same subnet and unique. For example, if the outdoor bridge’s IP address is 192.168.1.5 with a mask of 255.255.255.0, then the PC’s IP address should be 192.168.1.x with a mask of 255.255.255.0. Transmission performance is slow or erratic. 1. Change the direction of the antenna slightly. 2. There may be interference, possibly caused by a microwave oven, 2.4GHz wireless phone, or metal objects. Move these interference sources or change the location of the wireless PC or AP. 3.
