Identifying disturbance events at point to point radio links

Abstract

The present disclosure relates to a point to point radio link arrangement () comprising at least two link nodes (). A first link node () is arranged to obtain first link data (X) over a first carrier frequency, and a second link node() is arranged to obtain second link data (X) over a second carrier frequency separate from the first carrier frequency. The link arrangement () further comprises a classification unit () arranged to obtain the link data (X, X) from the link nodes () and to determine if the link data (X, X) are affected by either a frequency dependent disturbance event or by a frequency independentdisturbance event. This is accomplished by comparing the first link data (X) to the second link data (X) over a time window (T). The classification unit () is also arranged to output disturbance event decision data (Y) in dependence of whether the link data (X, X) have been determined to be affected by either a frequency dependent disturbance event or a frequency independent disturbance event.
