    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.

    The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN, but also increases the effective wireless transmission range for wireless PCs by passing their signals through one or more access points. A wireless infrastructure can be used for access to a central database, or for connection between mobile workers, as shown in the following figure.

  • Page 30: Radio Path Planning

    Bridge Link Planning Radio Path Planning Although the wireless bridge uses IEEE 802.11a radio technology, which is capable of reducing the effect of multipath signals due to obstructions, the wireless bridge link requires a “radio line-of-sight” between the two antennas for optimum performance.

  • Page 31: Antenna Height

    • Check the topology of the land between the antennas using topographical maps, aerial photos, or even satellite image data (software packages are available that may include this information for your area) • Avoid a path that may incur temporary blockage due to the movement of cars, trains, or aircraft.

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.

  • Page 34: Ethernet Cabling

    Bridge Link Planning • Snow and Ice — Falling snow, like rain, has no significant effect on the radio signal. However, a build up of snow or ice on antennas may cause the link to fail. In this case, the snow or ice has to be cleared from the antennas to restore operation of the link.

  • Page 35: Chapter 4: Hardware Installation

    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.

(The bracket may need to be rotated around the pole during the alignment process.) Attach bracket to pole with mounting grooves facing up...

  • Page 37: Mounting On Larger Diameter Poles

    Mounting on Larger Diameter Poles In addition, there is a method for attaching the pole-mounting bracket to a pole that is 2 to 5 inches in diameter using an adjustable steel band clamp (not included in the kit). A steel band clamp up to 0.5 inch (1.27 cm) wide can be threaded through the main part of the bracket to secure it to a larger diameter pole with out using the U-shaped part of the bracket.

  • Page 38: Connect External Antennas

    Typically, a bridge link requires a 5 GHz antenna and access point operation a 2.4 GHz antenna. AWAP05O Slave units also require an external antenna for 2.4 GHz operation.

  • Page 39: Connect Cables To The Unit

    Connect Cables to the Unit The wireless bridge’s Ethernet port does not support Power over Ethernet Caution: (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. Always connect the unit to the included power injector module.

  • Page 40: Align Antennas

    Hardware Installation Ethernet cable from LAN switch Insert the power cable plug directly into the standard AC receptacle on the power injector. 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.
  • Page 41 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.
  • Page 42 Hardware Installation 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. Find the point where the signal is strongest (highest voltage) and secure the horizontal adjustment in that position.

  • Page 43: Chapter 5: Initial Configuration

    Chapter 5: Initial Configuration The wireless bridge offers a variety of management options, including a web-based interface, a command line interface (CLI), or using SNMP management software. Most initial configuration steps can be made through the web browser interface using the Setup Wizard (page 5-3). However, for units that do not have a preset country code, you must first set the country code using the CLI.

  • Page 44: Initial Configuration Steps

    Initial Configuration Initial Configuration Steps Setting the Country Code – Regulations for wireless products differ from country to country. Setting the country code restricts the wireless bridge to use only the radio channels and power settings permitted in the specified country of operation. If the wireless bridge unit is shipped with a preset country code, you are not permitted to change it, as required by country regulations.

    Advanced Configuration Spanning Tree Protocol (STP) The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the wireless bridge to interact with other bridging devices (that is, an STP-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
