<p>Known is a communication method for use in a communication system comprising at least one primary radio station and a plurality of secondary radio stations, in which method a primary radio station communicates with a secondary radio station comprising a controllable antenna structure coupled to a transceiver, and in which method a geomagnetic field is sensed. It is proposed that the secondary radio station is a portable radio sation which can be freely oriented with respect to a fixed coordinate system, that the geomagnetic field is sensed three-dimensionally, and the controllable antenna structure is controlled on the basis of three-dimensional sensing information, such that, after an intial adjustment of the controllable antenna structure to a predetermined direction, the antenna structure substantially remains directed in the predetermined direction, irrespective of an orientation of the portable radio station.</p> |
