Abstract
An example of a lighting device including a light source, a modulator and a processor. The processor is configured to control the light source to emit light for general illumination and control the modulator to modulate the intensity of the emitted light to superimpose at least two sinusoids. Frequencies of the at least two sinusoids enable a mobile device to infer the physical location of the lighting device.
