Alignment
Figure 41.
Following are the steps involved for Alignment:
i) Verify isolation between Bridge A and B:
• Establish Link1 and align the antennas (Bridge A is the root bridge C is non-root)
• Install Bridge B at least 10 feet away and configure as non-root and let it associate to bridge
A.
• Measure RSSI voltage and make sure it is less than 2 V (-40 dBm), if not move bridge B
further away
ii) Verify isolation between Bridge A and D:
• Install Bridge D at least 10 feet away from Bridge C and align it to associate bridge A.
• Measure RSSI voltage and make sure it is less than 2 V (-40 dBm), if not reduce the power
on all bridges to 12 dBm, if RSSI is still larger alternate polarization of link 2
iii) Verify Isolation between Bridge C and D:
• Shut down bridge A, configure bridge C as root then let Bridge D associate to it
• Measure RSSI voltage and make sure it is less than 2 V (-40 dBm), if not move bridge D
further away
Note: The isolation between Bridge C and B is symmetrical to the isolation between A
and D
iv) Configure link1:
• Re-establish link1 by configuring the root (A) and non-root (C) bridges accordingly
• Set the channel on bridge A 5745 MHz or 5765 MHz
• Align bridge A and C by maximizing the RSSI
v) Configure link2:
