Apparatus for visible light communication indicating communication quality using RGB color mixing and method thereof

摘要

visible light communication apparatus of the present invention , the transmitting terminal from the received visible light signal received from the target wavelength of the signal only receiving unit for filtering the target signal ; Determining the reception quality of the received signal using the visible light of the target wavelength and the characteristics of the signal , the signal generator for generating a visible signal by using at least one light source in accordance with the reception quality with a target wavelength and different wavelengths ; And the data signal of the target wavelength to be transmitted is transmitted together with the visible signal to an optical signal transmission unit such that the luminous color of the visible light transmission signal is changed . According to the present invention , allows in the communication using visible light to a user has an effect that enables recognition of the current communication quality as color .
