1 1-10 Introduction
Chapter 2: Network Configuration The Dual-band Outdoor Access Point / Bridge system provides access point or bridging services through either the 5 GHz or 2.4 GHz radio interfaces. The wireless bridge units can be used just as normal 802.11a/b/g access points connected to a local wired LAN, providing connectivity and roaming services for wireless clients in an outdoor area. Units can also be used purely as bridges connecting remote LANs.
2 Network Configuration Ad Hoc Wireless LAN Notebook with Wireless USB Adapter Notebook with Wireless PC Card PC with Wireless PCI Adapter Infrastructure Wireless LAN The access point function of the wireless bridge provides access to a wired LAN for 802.11a/b/g wireless workstations. An integrated wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users and an access point that is directly connected to the wired LAN.
2 Access Point Topologies Infrastructure Wireless LAN for Roaming Wireless PCs The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point. The BSS ID is used in frames sent between the access point and its clients to identify traffic in the service area.
2 Network Configuration Bridge Link Topologies The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge connections between BSS areas (access points). The outdoor wireless bridge uses WDS to forward traffic on links between units. Up to 16 WDS links can be specified for a OAP6626A unit configured as a “Master” in the wireless bridge network. OAP6626A slave units support only one WDS link, which must be to the network’s master unit.

Chapter 3: Bridge Link Planning The Dual-band Outdoor Access Point / Bridge supports fixed point-to-point or point-to-multipoint wireless links. A single link between two points can be used to connect a remote site to larger core network. Multiple bridge links can provide a way to connect widespread Ethernet LANs. For each link in a wireless bridge network to be reliable and provide optimum performance, some careful site planning is required.
3 Bridge Link Planning Distances Achieved Using Normal Mode Data Rate 17 dBi Integrated 8 dBi Omni 13.5 dBi 120-Degree Sector 16.5 dBi 60-Degree Sector 23 dBi Panel 48 Mbps 2.9 km 0.4 km 1.2 km 2.3 km 9.2 km 54 Mbps 1.8 km 0.2 km 0.7 km 1.5 km 5.8 km Distances provided in this table are an estimate for a typical deployment and may be reduced by local regulatory limits. For accurate distances, you need to calculate the power link budget for your specific environment. .
Radio Path Planning 3 The following figure illustrates the concept of a good radio line-of-sight. Visual Line of Sight Radio Line of Sight If there are obstacles in the radio path, there may still be a radio link but the quality and strength of the signal will be affected. Calculating the maximum clearance from objects on a path is important as it directly affects the decision on antenna placement and height.
3 Bridge Link Planning Antenna Height A reliable wireless link is usually best achieved by mounting the antennas at each end high enough for a clear radio line of sight between them. The minimum height required depends on the distance of the link, obstacles that may be in the path, topology of the terrain, and the curvature of the earth (for links over 3 miles). For long-distance links, a mast or pole may need to be contsructed to attain the minimum required height.
Radio Path Planning 3 Radio Line of Sight Visual Line of Sight 3 miles (4.8 km) 2.4 m A 5.4 m B 1.4 m 9m 20 m 17 m 12 m A wireless bridge link is deployed to connect building A to a building B, which is located three miles (4.8 km) away. Mid-way between the two buildings is a small tree-covered hill. From the above table it can be seen that for a three-mile link, the object clearance required at the mid-point is 5.3 m (17.4 ft).
3 Bridge Link Planning direction. The unit should be mounted with the antenna sockets facing upwards and both console and POE ports pointing downwards. Antenna sockets should point upwards in a vertical manner Radio Interference The avoidance of radio interference is an important part of wireless link planning. Interference is caused by other radio transmissions using the same or an adjacent channel frequency.
Ethernet Cabling 3 are all properly grounded. Additional protection using lightning rods, lightning arrestors, or surge suppressors may also be employed. • Rain — The wireless bridge is weatherproofed against rain. Also, prolonged heavy rain has no significant effect on the radio signal. However, it is recommended to apply weatherproof sealing tape around the Ethernet port and antenna connectors for extra protection.

Chapter 4: Hardware Installation Before mounting antennas to set up your wireless bridge links, be sure you have selected appropriate locations for each antenna. Follow the guidance and information in Chapter 2, “Wireless Link Planning.” Also, before mounting units in their intended locations, you should first perform initial configuration and test the basic operation of the wireless bridge links in a controlled environment over a very short range.
4 2. Hardware Installation Place the V-shaped part of the bracket around the pole and tighten the securing nuts just enough to hold the bracket to the pole. (The bracket may need to be rotated around the pole during the alignment process.
Mount the Unit 4 Attach the adjustable rectangular plate to the bridge with supplied screws Attach the bridge with bracket to afixed plate on pole 3. Use the included nuts to tightly secure the wireless bridge to the bracket. Be sure to take account of the antenna polarization direction; all antennas in a link must be mounted with the same polarization.
4 Hardware Installation Using the Wall-Mounting Bracket Perform the following steps to mount the unit to a wall using the wall-mounting bracket: Note: The wall-mounting bracket does not allow the wireless bridge’s intrgrated antenna to be aligned. It is intended for use with the unit using an external antenna. 1. Always attach the bracket to a wall with flat side flush against the wall (see following figure). 2.
Connect External Antennas 4 Connect External Antennas When deploying a OAP6626AM Master bridge unit for a bridge link or access point operation, you need to mount external antennas and connect them to the bridge. Typically, a bridge link requires a 5 GHz antenna, and access point operation a 2.4 GHz antenna. OAP6626A Slave units also require an external antenna for 2.4 GHz operation. Perform these steps: 1.
4 Hardware Installation OAP6626A 2.4 GHz N-type Connector 2.4 GHz N-type Connector 5 GHz N-type Connector 5 GHz External High-gain Panel Antenna 2.4 GHz External Omnidirectional Antenna RF Coaxial Cable Connect Cables to the Unit 1. Attach the Ethernet cable to the Ethernet port on the wireless bridge. Note: The Ethernet cable included with the package is 30 m (100 ft) long. To wire a longer cable (maximum 100 m, 325 ft), use the connector pinout information in Appendix B. 2.
Connect the Power Injector 4 Ground Wire Ethernet Cable Connect the Power Injector To connect the wireless bridge to a power source: Caution: Do not install the power injector outdoors. The unit is for indoor installation only. Note: The wireless bridge’s Ethernet port does not support Power over Ethernet (PoE) based on the IEEE 802.3af standard. Do not try to power the unit by connecting it directly to a network switch that provides IEEE 802.3af PoE.
4 Hardware Installation AC power Ethernet cable from LAN switch Inp ut Ou tpu t Power LED indicator Ethernet cable to wireless bridge 3. Insert the power cable plug directly into the standard AC receptacle on the power injector. 4. Plug the other end of the power cable into a grounded, 3-pin socket, AC power source. Note: For International use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country. 5.
Align Antennas 4 The RSSI connector provides an output voltage between 0 and 3.28 VDC that is proportional to the received radio signal strength. The higher the voltage reading, the stronger the signal. The radio signal from the remote antenna can be seen to have a strong central main lobe and smaller side lobes. The object of the alignment process is to set the antenna so that it is receiving the strongest signal from the central main lobe.
4 Hardware Installation Voltmeter RSSI Connection 2. Pan the antenna horizontally back and forth while checking the RSSI voltage. If using the pole-mounting bracket with the unit, you must rotate the mounting bracket around the pole. Other external antenna brackets may require a different horizontal adjustment. 3. Find the point where the signal is strongest (highest voltage) and secure the horizontal adjustment in that position.
Appendix A: Troubleshooting Check the following items before you contact local Technical Support. 1. If wireless bridge units do not associate with each other, check the following: • Check the power injector LED for each bridge unit to be sure that power is being supplied • Be sure that antennas in the link are properly aligned. • Be sure that channel settings match on all bridges • If encryption is enabled, ensure that all bridge links are configured with the same encryption keys. 2.

Appendix C: Cables and Pinouts Twisted-Pair Cable Assignments For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.
C Cables and Pinouts 10/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). The RJ-45 Input port on the power injector is wired with MDI pinouts.
8-Pin DIN Connector Pinout C Crossover Wiring Because the 10/100 Mbps port on the power injector uses an MDI pin configuration, you must use “crossover” cable for network connections to PCs, servers or other end nodes that only have MDI ports. However, if the device to which you are connecting supports automatic MDI/MDI-X operation, you can use either “straight-through” or “crossover” cable.
C Cables and Pinouts 8-Pin DIN to RJ-45 Cable Wiring To construct an extended Ethernet cable to connect from the power injector’s RJ-45 Output port to the wireless bridge’s 8-pin DIN connector, follow the wiring diagram below. Use Category 5 or better UTP or STP cable, maximum length 100 m (328 ft), and be sure to connect all four wire pairs. Note: To construct a reliable Ethernet cable, always use the proper tools or ask a professional cable supplier to construct the cable.
Glossary 10BASE-T IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3 or better UTP cable. 100BASE-TX IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 or better UTP cable. Access Point An internetworking device that seamlessly connects wired and wireless networks. Access points attached to a wired network, support the creation of multiple radio cells that enable roaming throughout a facility.
Glossary dBm The unit dBm refers to a precise measure of power based upon the decibel scale, but referenced to the milliwatt: i.e. 1 dBm = .001 Watt. The dBm is often used to describe absolute power level where the point of reference is 1 milliwatt. Dynamic Host Configuration Protocol (DHCP) Provides a framework for passing configuration information to hosts on a TCP/IP network.
