Abstract: An electronic device for point-to-multipoint transmission of a digital signal over a radio communication network includes a transmitter-receiver configured to receive a radio-frequency input digital signal and generate therefrom a baseband digital signal and includes a digital signal processor. The digital signal processor includes a receiving module, an input buffer, an audio decoder module and an output buffer. The transmitter-receiver is further configured to receive the duplicated baseband output digital signal and generate therefrom a radio-frequency output digital signal. The transmitter-receiver is configured to receive the radio-frequency input digital signal on the basis of Bluetooth® specifications and transmit the radio-frequency output digital signal on the basis of Bluetooth® specifications, and the microcontroller is configured to realize a unidirectional asynchronous packet data link.
