The disclosure relates to a lighting fixture, which includes an array of solid-state light sources that are configured to generate light for general illumination lighting purposes and control circuitry. A drive signal is used to drive solid-state light sources. The control circuitry is configured to use a control output to control the drive signal to at least one of the solid-state light sources. The control output is configured to control the drive signal to 1) set at least one characteristic of the light generated by the array of the solid-state light sources, and 2) modulate the light with data for transmission. The light is modulated such that any change in the at least one characteristic based on the light being modulated is anthropically imperceptible. The characteristic of the light generated by the array of solid-state light sources may include the intensity, color, color temperature and the like.
