Abstract

A radio communication system for transmitting voice or music data includes a data supplying source device for supplying the voice or music data, the data supplying source device having a reflector for transmitting a reflected wave signal obtained by modulating a received radio wave based on the data to be transmitted; and a data supply destination device for receiving the voice or music data, the data supply destination device having a reflected wave reader for transmitting an unmodulated carrier and for reading a reflected wave signal resulting from modulation of the unmodulated carrier. The voice or music data is transmitted by reflected wave transmission between the data supplying source device and the data supply destination device.
