Abstract: A smart radio system includes a mobile device and a radio device. The mobile device includes a signal processing module for processing a received signal to be outputted as a processed result or processing signals generated by a signal source to be a transmission signal; a user interface for generating a control signal; and a first transmission module for receiving the received signal to be transmitted to the signal processing module or outputting the transmission signal according to the control signal. The radio device includes a real-time communication module for receiving the received signal or transmitting the transmission signal via wireless transmission; and a second transmission module for transmitting the transmission signal outputted by the first transmission module to the real-time communication module or transmitting the received signal received by the real-time communication module to the first transmission module.
