Site Planning
Prior to installation, develop a checklist that covers all aspects of the installation. 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 13
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.

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.
Chapter 3 Hardware Installation Page 22
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 4 Configuration Page 23
Chapter 4 Configuration
The units to be installed should be configured before physical installation. During this process,
the installer can set the unit’s 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 bridge’s
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 injector’s 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 bridge’s IP
address in the address filed and press Enter.

keys manually. These keys must match the ones of other wireless stations or bridges.
Only 8 to 63 characters can be entered.
Key1~Key4: Select the key to be used as the default one and data transmissions are
always encrypted using this default key. The other keys are only used to decrypt received
data.
Chapter 5 Troubleshooting Page 31
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
