Abstract
A visible light communication apparatus and a method for visible light communication are provided. The method includes calculating a quantity of terminals in coverage of each of a plurality of visible light sources. The visible light sources include a first visible light source and a second visible light source. Determining a quantity of the sub-bands according to the quantity of terminals. The sub-bands include a first sub-band and a second sub-band. Distributing the first sub-band for the first visible light source and the second sub-band for the second visible light source according to the quantity of terminals in coverage of each of the visible light sources, in which the first sub-band and the second sub-band are different from each other. Allocating a bandwidth for each of the terminals according to the distributed sub-bands or a user requirement. Modulating a transmission data on one of the first sub-band and the second sub-band.
