Claims9
A visible-light wireless communication system for visible-light communication with terminals, comprising:
- a plurality of light transmitters for generating light signals modulated in different frequencies for wireless communication with the terminals,
- wherein the plurality of light transmitters each include a light source for outputting light and a frequency converter for frequency modulation of the light source,
- wherein each frequency converter included in each respective light transmitter has a different capacitance, to output different frequencies from the plurality of light transmitters.
A visible-light wireless communication method, comprising:
- generating a plurality of light signals modulated in different frequencies using different capacitances;
- and
- combining and transmitting the plurality of light signals having different frequencies,
- wherein the generating of the plurality of light signals comprises outputting light and frequency modulation of the plurality of light signals using different capacitances to output different frequencies.
