Abstract: A test apparatus includes: a communication interface for connection to a enodeb of a mobile telecommunication network provided with beamforming functionality, the communication interface being configured to receive communication traffic between the enodeb and a mobile terminal coupled in communication to the enodeb (3); a beamforming-testing unit, configured to receive communication-channel-quality signals (RSRPS) corresponding to each communication beam (B1, B2, . . . , BN), the communication-channel-quality signals (RSRPS) representing a signal power received by the mobile terminal. The beamforming-testing unit checks whether communication settings of the enodeb in relation to selection of the communication beams (B1, B2, . . . , BN) are consistent with the communication-channel-quality signals (RSRPS).
