1. Method for data transmission, in particular on the basis of the Bluetooth standard, in which data packets can be interchanged by radio by using time slots, the method comprising:

  • establishing a first communication channel between a master subscriber and a first slave subscriber;

    operating the first communication channel to perform data exchange during a first time slot followed by a first subsequent time slot in which no data exchange occurs;

    establishing a second communication channel between the master subscriber and a second slave subscriber;

    operating the second communication channel to perform data exchange during a second time slot followed by a second subsequent time slot in which no data exchange occurs, operating the second communication channel including synchronizing the second communication channel to the first communication channel;

    wherein synchronizing the second communication channel includes causing data exchange during a specified time slot, the specified time slot determined based upon a time slot in which data exchange occurs in the first communication channel; and

    determining a synchronization parameter for synchronization of the second communication channel, the synchronization parameter defining a phase offset between a first data interchange and a second data interchange, the first data interchange between the master subscriber and the first slave subscriber via the first communication channel and the second data interchange between the master subscriber and the second slave subscriber via the second communication channel.
