Radio station arranged for space-diversity and polarization diversity reception

A radio station comprising a base station for wireless telecommunication to/from one or more mobile stations, the radio station comprising:

• a number of units, at least one unit comprising a transmitter, a receiver, and means for diversity reception, and each of said units comprising at least one antenna which is arranged to be placed at a predetermined distance from one or more antennas in other units, the antenna(s) included in each unit arranged for reception with space-diversity in cooperation with at least one antenna in any of the other units, the antenna(s) within each unit arranged for reception of signals with different polarization directions for achieving polarization-diversity, and the means for diversity reception evaluating the input signals from the antennas, which input signals originate both from the reception from the antennas with different placement in space and from the reception with different polarization directions, and wherein each unit includes an attachment arrangement which is arranged to ensure a predetermined placement of each unit relative to other units with respect to mutual distance as well as direction.
