Taking measurements

The result of the measurement is that the signal strength is sufficient for synchronisation
everywhere. Base station E only receives base station D with sufficient quality.
Here, a sensible synchronisation hierarchy would be:
Sync level 1 Base station C
Sync level 2 Base stations A, B and D
Sync level 3 Base station E
