Abstract:
1. A communication partner device which belongs to a communication system having at least two such communication partner devices and which is designed to communicate with another communication partner device of the communication system over a first communication channel, wherein one of the two communication partner devices contains a communication enable information item which is used to enable communication between the one communication partner device and the other communication partner device over the first communication channel, and which is designed to interact with an electrical circuit, which circuit has circuit parts for forming communication means which are designed for contactless communication with communication means of the other communication partner device over a second communication channel and which, in the event of communication over the second communication channel, are designed to make available the communication enable information item, necessary for enabling communication over the first communication channel, in the communication partner device which prior to communication over the second communication channel does not yet contain the communication enable information item, wherein the electrical circuit includes a plurality of interfaces configured for communication over the first communication channel, the interfaces including a Bluetooth interface, an infra-red light interface, and a wireless large area network interface for communication over the first communication channel, the electrical circuit further including a transmission device configured for transmission of carrier signals over the second communication channel, wherein the communication means are designed, in the event of communication over the second communication channel, to communicate in accordance with a communication protocol, and wherein the communication means are designed to make available the communication enable information item by using at least one of two activation commands of the communication protocol, which activation commands can be communicated between the two communication partner devices in accordance with the communication protocol as first commands over the second communication channel and are provided in order to activate communication in compliance with the communication protocol.
