HANDS-FREE DEVICE FOR OPERATING DIFFERENT TYPES OF MOBILE RADIO DEVICES

摘要

The invention relates to a telecommunications device for operating different types of mobile radio devices in a motor vehicle. The aim of the invention is to provide a universal telecommunications device, which enables mobile radio devices to be used either in a wireless or wired manner, depending on their configuration or optionally as an authentication unit to permit the use of a mobile radio device account by other units. To achieve said aim, the inventive telecommunications device consists of a type-independent base unit containing a control unit and one of several type-specific adapters comprising an interface for adapting the electrical specifications of a mobile radio device to the control unit. At least one of the adapters is configured for the wireless operation of a correspondingly configured mobile radio device by means of the telecommunications device. According to the invention, said adapter comprises its own mobile radio transceiver and is in mechanical and electrical contact with the adapter socket that is fixed in the vehicle. During the operation of a mobile radio device by means of said telecommunications device, the entire communication takes place exclusively by means of the mobile radio transceiver that is located in the adapter.
