Chapter 8: Troubleshooting Testing the radio link
Page 8-13
Testing the radio link
This section describes how to test the link when there is no radio communication, when it is
unreliable, when the data throughput rate is too low, or when a unit is causing radio or TV
interference. It may be necessary to test the units at both ends of the link.
No activity
If there is no wireless activity, proceed as follows:
1 Check for Alarm conditions on Home page.
2 Check that the software at each end of the link is the same version.
3 Check that the Target Mac address is correctly configured at each end of the link.
4 Check Range.
5 Check Tx Power.
6 Check License keys to ensure that both units are the same product variant.
7 Check Master/Slave status for each unit and ensure that one unit is Master and the other unit
is slave.
8 Check that the link is not obstructed or the ODU misaligned.
9 Check the DFS page at each end of the link and establish that there is a quiet wireless channel
to use.
10 If there are no faults found in the configuration and there is absolutely no wireless signal,
retry the installation procedure.
11 If this does not work then report a suspected ODU fault to Cambium Networks.
Some activity
If there is some activity but the link is unreliable or does not achieve the data rates required,
proceed as follows:
1 Check that the interference has not increased using the DSO measurements.
2 If a quieter channel is available check that it is not barred.
3 Check that the path loss is low enough for the communication rates required.
4 Check that the ODU has not become misaligned.
