Switched-beam antenna arrangement means use a method of controlling an antenna pattern of such antenna arrangement means. Each antenna pattern of a predetermined number of fixed antenna patterns is allocated to a predetermined time slot of a time multiplexed signal. The switched-beam antenna arrangement means is switched to generate the fixed antenna patterns during their allocated time slots. Thereby, any user can choose between distinct beam patterns by selecting an appropriate time slot, so that the risk that the user is located at the intersection area of two beams is greatly reduced.
