  • illuminating a radio area to be covered by the stationary radio transmission/reception device by at least two individual directional antennas, the at least two individual directional antennas forming the stationary antenna device;

    providing radio sub-areas of the radio area;

    covering each respective radio sub-area of the radio area with a respective one of the at least two individual directional antennas; and

    activating in antenna diversity fashion a respective one of the at least two individual directional antennas in whose respective radio sub-area the mobile radio transmission/reception device is located, wherein only one of the at least two individual directional antennas is activated at any one point in time for both transmitting and receiving data to and from the mobile antenna device.
