    • A communications system for a motor vehicle in which the hands-free device for a mobile phone is integrated into an audio or information system of the motor vehicle such as a car radio. The voice and/or data transmission between the mobile phone and the hands-free device takes place over an additional short-range radio link. A transceiver for this short-range radio link is contained both in the car radio and in the mobile phone. The need to install additional connection interfaces is thus eliminated. In addition, the need to couple the mobile phone to the hands-free device using a cable is eliminated. This has the advantage that the mobile phone can remain, for example, in the driver's pocket. The coupling between the mobile phone and car radio occurs automatically if the mobile phone moves into the range of the short-range radio link of the car radio.
    • 一种用于机动车辆的通信系统,其中将用于移动电话的免提装置集成到诸如汽车无线电的汽车的音频或信息系统中。 移动电话和免提设备之间的语音和/或数据传输通过附加的短距离无线电链路进行。 用于该短距离无线电链路的收发器包含在汽车收音机和移动电话中。 因此,消除了安装附加连接接口的需要。 此外,消除了使用电缆将手机耦合到免提装置的需要。 这具有移动电话可以保持在例如驾驶员口袋中的优点。 如果移动电话移动到无线电广播的短距离无线电链路的范围内,则手机和汽车收音机之间的耦合将自动发生。
