Method to determine the existence of interferences in a wireless communication link based on comparing the power received at both links of radio channel and the propagation losses calculated from both power and quality measurements, comprising:(i) gathering values RXLEV_UL and RXLEV_DL;(ii) using said values to estimate the receiver power level in the base station;(iii) statistical analysis of the two different estimations obtained (PRXLEV ULi, and {tilde over (P)}{tilde over (PULi)}) for every connection i in the radio link;(iv) comparing the estimations (PRXLEV ULi and {tilde over (P)}{tilde over (PULi)}) of the uplink received signals strength with the quality parameters RXQUAL_UL and RXQUAL_DL;(v) computing the behavior of the computed values psi and Rsnri,(vi) analyzing the results to detect:(a) steady-state abnormalities;(b) unbalanced interferences;(c) malfunctioning of the power control; and(d) inadequate radio planning.
