1. A point to point radio link arrangement, comprising:
at least two link nodes, wherein:
a first link node is arranged to obtain first link data (X1) over a first carrier frequency; and
a second link node is arranged to obtain second link data (X2) over a second carrier frequency separate from the first carrier frequency;
a classification unit configured to:
obtain the link data from the at least two link nodes;
determine if the link data are affected by either a frequency dependent disturbance event or by a frequency independent disturbance event by comparing the first link data to the second link data over a time window; and
output disturbance event decision data based on whether the link data have been determined to be affected by either the frequency dependent disturbance event or the frequency independent disturbance event.
