Abstract

The radio area to be covered by the stationary radio transmission/reception device, for example of the base station of a cordless telephone, is illuminated by two or more directional antennas (3, 4) respectively covering a radio sub-area thereof, whereby that respective directional antenna in whose radio sub-area the mobile radio transmission/reception means, i.e., for example, the mobile part of the cordless telephone, is located is activated (antenna diversity). The method and apparatus can be advantageously utilized in cordless telephones.
