A well-developed plan identifies potential problems early so that they can be solved timely. Choosing a Mounting Location Choosing a good mounting location for the bridge is important because it affects the reliability of the wireless link and maximum data rates the bridge system can achieve. The most important considerations are distance between bridges and clearance from obstacles. Signal path distance and clearance In an environment without obstacles in the signal path, the maximum distance between bridges depends primarily on the type of antennas and the free space loss between them. Make sure your proposed mounting site is within range of the remote antenna. Another consideration when planning a wireless link is the Fresnel Zone, which occupies a series of concentric ellipsoid-shaped areas around the LoS path as below:
Chapter 2 Preparation before Installation Page 12 The Fresnel Zone is important to the wireless link as it defines an area around the LoS that can introduce RF signal interference if blocked. Objects in the Fresnel Zone such as trees and buildings can diffract or reflect the main signal away from the receiver, changing the RF LoS. Antenna Polarization The integrated antenna radiates and receives polarized radio signals. For the link to operate correctly, two antennas at each end of the link must always be set for the same polarization, either vertical or horizontal.

Chapter 3 Hardware Installation Page 20 Align Antenna After powering up the wireless bridge, align the integrated antenna to point in the approximate direction of the remote bridge antenna. If the antenna is at a significant angle, use binoculars, satellite global positioning system (GPS) or reference objects to detect the remote bridge or antenna, and then manually adjust the horizontal and vertical positions accordingly. To verify whether the two antennas are correctly pointed to each other, ping the remote wireless bridge. Positioning antenna is to align the local antenna to reach maximum signal strength. Using Align Antenna to measure signal strength is convenient and appropriate for most installations, but note that this method is only available in Peer-to-Peer (CSMA) mode. To use Align Antenna, follow the steps bellow:
1. Login the Web-based management interface of wireless bridge;
2. Open Peer-to-Peer Setup, by clicking Align Antenna, Antenna Alignment Tool window will popup. Set the target RSSI and click Start to begin alignment. If the RSSI is below -70 dBm, align the antenna by panning the antenna from side to side and tilting up and down while observing the RSSI value. By doing so, you will be able to know where is the best position for the antenna to reach its maximum signal strength. During adjustment, the device will send out the beep sound, assisting you with the alignment. 3. After the two integrated antennas are well positioned, secure the bridge mounting fasteners. The bridges now are ready to be configured and incorporated into your network. Chapter 3 Hardware Installation Page 21 Chapter 4 Configuration The units to be installed should be configured before physical installation. During this process, the installer can set the units IP address to the one within desired address range and set each unit up with the MAC address of its peer unit ready to establish a wireless link. It is recommended that this procedure be carried out on the bench before physical installation. This chapter describes how to configure your bridge for the first time. You can use the bridges web-based interface to complete the initial configuration. Connect the Bridge to a Local Computer If you are configuring the bridge locally (without connecting its power injector to a wired LAN), connect a PC to the power injectors Ethernet port using a Category 5 Ethernet cable. 1. Assign a static IP address to your PC which is in the same network segment with the wireless bridge. As the default IP address of this unit is 192.168.1.1, you may choose from 192.168.1.2 to 192.168.1.254. 2. Test the link status between your PC and the wireless bridge. Start a command prompt and execute a continuous ping command ping 192.168.1.1 t. If ping to the wireless bridge is successful (as shown below), open Internet browser and enter the bridges IP address in the address filed and press Enter. Chapter 4 Configuration Page 22 3. Enter the user name (admin) and password (password) to login and make configurations. 4. After configuring the bridge, remove the Ethernet cable from PC and connect the power injector back to your wired LAN port. Basic Settings After login to the Web-based management interface, you will see the About page as below. Click Basic in the left menu bar to make basic system configurations. Chapter 4 Configuration Page 23 IP Address Enter the settings obtained from your system administrator. The most important setting is IP Address. You may manually assign an IP address or check DHCP to automatically obtain one from DHCP server on your network. Note:
Do not change the IP address of the bridge while you are configuring with Web-based management interface, otherwise you will disassociate from it! If this occurs, login again with that new IP address; if DHCP is enabled then, login again by entering bridges wireless device name in the IP address field. Operating Mode Four operating modes are available in this bridge: Base Station, CPE, Peer to Peer (CSMA) and Peer to Peer (TDMA). Open Radio in Wireless and select the mode suitable for your application. Base Station Under this mode, the bridge connects directly to the main Ethernet LAN and receives connectivity from other CPE bridges. Chapter 4 Configuration Page 24 CPE Under this mode, the bridge connects to a remote LAN and that Base Station. Select Multicli or LAN-to-LAN for your network application and specify the SSID of the corresponding Base Station. Chapter 4 Configuration Page 25 Peer to Peer (CSMA) Under peer-to-peer (CSMA) mode, set the same channel for all the peer units. Open Peer-to-Peer Links (as below) page to enter the MAC address of the remote peer unit. Peer to Peer (TDMA) Under peer-to-peer (TDMA) mode, set one group ID for all the peer units. Chapter 4 Configuration Page 26 Base Station ID The SSID is a unique identifier that bridges use to associate to each other. It is case-sensitive and consists of no more than 32 alphanumeric characters. By default, it is set to Wireless. Output Power If the bridges are installed less than 328ft (100m) apart, the output power should be adjusted lower to avoid overloading the bridges receivers. To configure the output power, open Radio and select the appropriate output power value:
Full, Half, and Quarter. Channel/Frequency Channel varies much as the available band differs from country to country. Select a proper operating channel in the drop-down list according to your situation. Advanced Settings After basic settings, you might need to configure some parameters to optimize performance or enhance your network security. Super Mode The super mode is designed to enhance throughput by decreasing data waiting time slot. Open Radio and check Fast Frame, Burst or Compression box accordingly.

Chapter 4 Configuration Page 29 Chapter 5 Troubleshooting This chapter provides troubleshooting procedures for basic problems with the bridge. Q 1. What if my bridge fails to connect to the remote one?
Ethernet Link: Check the availability of power to the bridge by observing the LED status on the power injector.
- Green: The wireless bridge is connecting to the backhaul network.
- Off: The wireless bridge disconnects from the wired network, check whether the power cord and Ethernet cables to the network and bridge are correctly connected. Basic Configurations: Mismatched basic settings among bridges are the most common cause of connectivity fail. If the bridge does not associate with a remote bridge, check whether options in each device are identical. Security Settings: Remote bridges attempting to authenticate to your bridge must support the same security options configured in your bridge, such as WEP and WPA
(2)-PSK. If your bridge fails to associate with others, check whether the security settings are the same as your bridge settings. Antenna Alignment: If the methods above are all checked to be correct, you can observe and verify antenna alignment with RSSI value. Q 2. What if I forget my password?
You may restore the bridge to its factory default settings in Backup/Restore Settings from Management. Q 3. What if my bridge encounters a firmware failure?
Retrieve the settings you have backed up previously in Backup/Restore Settings from Management.
