Adjusting Link Profiles

Link planners need to verify and adjust link profiles for the following reasons:

• To enter accurate estimates of antenna heights.

• To correct the average terrain heights provided by the Path Profiler.

• To verify the clutter type (if used) provided by the Path Profiler

• To allow for obstructions in the link path (usually trees) when working without clutter.

• To add additional height to clutter where the default height is not sufficient for the local area.

• To allow for the effect of reflection when the link path is over water.

The process for each link is:

1. View the link in the Google Earth(TM) aerial photograph (if it is available), as described in Using Google Earth(TM).

2. Obtain the most accurate possible data at the two ends of the link, as described in Verifying Link Ends.

3. Obtain the most accurate possible data at the high points, as described in Verifying High Points.

4. Update the profiles as described in Updating Link Profiles.

For examples of how Cambium link planners use a map, Google Earth and surveys to adjust link profiles, see Link Profile Adjustment Examples.
