Abstract:
This paper investigates the maximum area covered by single light emitting diode (LED) or multiple LEDs for indoor visible light communication on the basis of received power. The main aim of this research is to predict how to find the right location of LEDâ€™s to provide minimum acceptable power in the receiver plane and number of LEDs required to cover the whole area of a room. The result showed that a single transmitter may cover 27.5m2 area at a 5m height with the acceptable value of received power, Pr = 1 Ã— 10-4mW The transmitter and receiver are line of sight (LOS).
