Method for checking a cable mating of a multi-band antenna

Abstract

The present invention relates to a method (1000) for checking a cable mating between a radio unit (20, 22, 24) and a multi-band antenna (10, 14). The method comprises: monitoring (1100) a voltage standing wave ratio, VSWR, of the radio unit; IC changing (1200) a phase shift of a phase shifter Φ1, . . . Φ8 being assigned to an antenna port R11A, . . . Y62A of the multi-band antenna 10; determining (1300) a port R11R, . . . Y62R of the radio unit 20, where a change in the VSWR of the radio unit occurred due to the changing of the phase shift; checking (1400), whether the determined port R11R, . . . Y62R of the radio unit 20 corresponds to the antenna port R11A, . . . Y62A of the multi-band antenna 10, where the phase shift was changed, and outputting (1500, 1600) the result of the checking.
