Through the increased applications of light emitting diode (LED) lamps for lighting in indoor and outdoor applications, industrial and academic interests have been risen towards adding communication functionality to the standard light emitting diode lamp illumination functionality in light-fidelity systems.

This paper reviews the different architectures of light-fidelity communication systems and develops a powerful systematic approach for assessing the energy efficiency and the communication system performance metrics for light-fidelity systems.
