Default Thresholds

Interference calculations require reference levels or thresholds against which they are judged.

These thresholds can be set by selecting Sharing Assignment Thresholds from the Settings menu.

Threshold Options Dialog
Threshold Options Dialog

There are three options:

  1. Use Recommendation ITU-R SF.1006 to calculate the thresholds

  2. Use values supplied in the data base per Assignment

  3. Set default values to be applied to all Assignments

Thresholds in Rec. SF. 1006 are given in terms of short and long term interference levels.

The other methods can also use I/N and ΔT/T values and associated percentages of time.
