Abstract:
The invention relates to a wireless, especially mobile, communication device (8) for communicating with communication devices (9) in vehicles (5, 6, 7). Said device comprises a transmitter (26), a receiver (29) for receiving electromagnetic waves containing information, and a control unit (25) for controlling the transmitter (26). A directional characteristic (10, 10') is provided for the receiver (29) and/or the transmitter (26), for selectively communicating with communication devices (9) in vehicles (5, 6, 7) at distances (D) of more than 10 m, preferably between 20 m and 200 m, e.g. approximately 100 m, especially at a receiver angle or emission angle of between 0.5 DEG and 4 DEG , preferably between 0.8 DEG and 2.5 DEG . The inventive device also comprises a viewing unit (13), and a display unit (16, 18) which is connected to the receiver (29) via a processing unit.
