FIELD: radio engineering, communication.SUBSTANCE: method includes an operation stage of at least two light sources (A, B) arranged to emit light (101) that has colour coordinates (x, y) and light intensity (Y), wherein each light source is arranged in order to emit light (101a, 101b), which can be distinguished from the light of at least one other light source, and a stage of integration of data in light, emitted by at least two light sources. The method further comprises of an operation stage of at least two light sources such that the colour coordinates of the light, emitted by at least two light sources, are stored over time within the first, limited interval (115), and the light intensity of the light, emitted by at least two light sources, is stored over time within a second, limited interval (116).EFFECT: enhanced communication reliability.8 cl, 14 dwg
