Abstract:
1. A radio device for transmitting radio signals, comprising: an electrical interface having at least one data terminal configured to connect the radio device to an external data source; a transmitting device in communication with the at least one data terminal and which generates the radio signals with data signals of the external data source, transmitted via the at least one data terminal; and an energy extraction device, the input of which is connected to the at least one data terminal and the output of which is connected to a power supply input of the transmitting device, and which takes energy from the data signals of the external data source and feeds the energy at the power supply input into the transmitting device, wherein the transmitting device includes another power supply input to connect an external power supply device, and the radio signals generated by the transmitting device exhibit a first predetermined transmitting power where the power is supplied by the energy extraction device and exhibit a second predetermined transmitting power exceeding the predetermined transmitting power where voltage/current is applied to the another power supply input.
