Abstract (en)
[origin: FR2828031A1] The base station (100) has a transmission antenna (1) with radiating elements (2). A radio signal is sent to a mobile telephone (200) within range. The phase of the radiating elements can be adapted controlling the radiation diagram. The phase shift is time independent of the destination mobile telephone.
