A number of coverage requirements are linked to the allocation of frequencies:
The details of the coverage requirements are defined in the allocation notification, the relevant geografical data can be found here and be viewed using a common GIS software (for example, the free Qgis).
The following figure shows the cadastral municipalities by coverage index:
The green, orange and red areas represent Austria's permanent settlement area, broken down according to cadastral municipalities. Red and orange areas are poorly or moderately covered cadastral municipalities (around 25% of all cadastral municipalities). These are addressed by the coverage requirements for cadastral municipalities.
The gray, light green and yellow areas describe the non-permanent settlement area, i.e. forest and mountains. This corresponds to about 60% of the area of Austria. These areas are partially covered, but they were not the target of the obligation.
