Abstract: Beamforming monitoring apparatus and method are disclosed. The method, comprises receiving (300) parameter data of radio connections between transceivers of a radio access network, the parameter data comprising transmission direction of the beams used in transmission and quality indicators related to transmitted beams; organising (302) data into one or more layers based on parameter data and connections at a given time resolution; receiving (304) a selection of layers at a given time instant; receiving (306) a selection of a view type; and controlling (308) displaying of the selected layers of the given time instant using the selected view type.

Abstract: A method and arrangement for testing wireless connections is provided. The method comprises obtaining (500) a three-dimensional model of a given environment; obtaining (502) ray tracing calculations describing propagation of radio frequency signals in the given environment; locating (504) one or more devices in the given environment; determining (506) utilising ray tracing calculations the radio frequency signal properties of one or more devices communicating with the device under test; transmitting (508) control information to the radio frequency controller unit for updating the connections between one or more devices and a set of antenna elements to match with the determined properties; obtaining (510) information on the location and propagation environment of the one or more devices and updating (512) the radio frequency signal properties of the one or more devices if the location or propagation environment changes.
