Viewing the Prediction Results

Display the power results using the deterministic two ray model (DTR).

  1. View the power using the DTR for the base station located on the highest hill.
    1. In the tree, expand Results: Propagation to view the results for the two base stations.
    2. In the tree, expand Highest_45 to view the base station on the highest hill.
    3. In the tree, expand Site 1 Ant 1 to view the result entries.
    4. In the tree, click Power to view the power result.

  2. View the power using the DTR for the base station located on a lower hill.
    1. In the tree, expand Results: Propagation to view the results for the two base stations.
    2. In the tree, expand Mediumheight_45 to view the base station on the lower hill.
    3. In the tree, expand Site 2 Ant 1 to view the result entries.
    4. In the tree, click Power to view the power result.

The DTR model only provides line-of-sight predictions. If the rays are shadowed by obstacles, the rays are not considered. The received power is only predicted for pixels which can be reached by the direct ray and/or the ground reflected ray. To get a prediction for the non-line-of-sight pixels, the DTR must be combined with the knife edge diffraction model to include the diffractions at the topographical obstacles.

The white pixels in the results indicate results below -120 dBm as the legend threshold range was specified from -30 dBm to -120 dBm.
