WinLink Technical Support C-137
RSS: –84 dBm minimum
There are cases when there is no line of sight, but still the link is of an
acceptable quality.
If the link is not within the acceptable limit, see Troubleshooting.
Troubleshooting
If the link is not within the acceptable limit as defined in Evaluating the
Link, check the following:
• Verify that both antennas have the same polarization
(horizontal/vertical).
• Check all the WinLink-AIND cable connectors for faulty
connections.
• Verify that there are no obstacles in the Fresnel zone of the
antenna path such as large buildings, trees, etc.
• Use a spectrum analyzer with suitable sensitivity to measure the
signal at the distance between the sites.
• If nothing improves the receive power level, check the overall link.
• Reduce the distance of the link–move the equipment from one site
closer to the other site–where it is possible to actually see the
antennas with the naked eye.
• If you now get the expected receive signal level, you can assume
that the equipment is operational, and the problem arises from
interference between the sites.
