The arrangement (1) has at least one transmission and reception antenna, a transmission unit and a reception unit, each connected to antenna. The transmission and reception antenna forms part of a remotely controllable access control device. A demultiplexer or galvanic changeover device (5) connected between the antenna (4) and evaluation unit (3) of the distance sensing arrangement and an evaluation unit (8) of the access control device (6) enables the antenna to be switched over between the sensing arrangement and the access control device. |
