Method for transmitting data between two subscribers

A method for transmitting data between a first subscriber and a second subscriber using at least one conversion unit,

• wherein the first subscriber, the second subscriber and the conversion unit are in each case configured for wireless data transmission in the near field with a first transmission method and a second transmission method,
• wherein the maximum data transmission rate of the second transmission method is higher than that of the first transmission method,
• wherein the second transmission method has a plurality of variants and wherein the first subscriber and the second subscriber are configured in each case to carry out only those variants which are incompatible with one another,
• comprising the steps of:
• a) periodic transmission of an identifier by the conversion unit and periodic transmission of an identification by the first subscriber and the second subscriber using the first transmission method,
• b) reception of the identifier of the conversion unit by the first subscriber and the second subscriber using the first transmission method, wherein the subscribers and the conversion unit similarly receive the transmitted identifications of the subscribers,
• c) setting up a direct wireless connection between the first subscriber and the second subscriber using the first transmission method, wherein the identifications of the subscribers and optionally the identifier of the conversion unit are exchanged.
• characterized in that the conversion unit is configured to carry out at least one variant of each subscriber, and in that the method furthermore comprises:
• d) setting up a connection switched by the conversion unit between the first subscriber and the second subscriber, wherein the subscribers in each case set up a connection to the conversion unit using the second transmission method and the conversion unit forwards data from the first subscriber to the second subscriber and, conversely, forwards data from the second subscriber to the first subscriber.
