Evaluate Number of LED on Reflector Room for Optical Wireless Communication

Abstract

Optical fiber communication system is the most implemented technology for backbone and access network telecommunication. However, the mobility of users has forced technology wired to wireless technology and one of the newest research is Optical Wireless Communication (OWC). The OWC has no longer using fiber optic as propagation media and using air for its transmission. In this paper, we evaluate number of Light Emitting Diode (LED) with comparison for one and two transmitters towards light communication distribution in a 5 m × 5 m × 4 m on closed room with reflector. We also use reflector mirror in the wall and using On Off Keying-Non Return to Zero (OOK-NRZ) as a modulation system. In addition, we evaluate wall reflector for impact of communication coverage area. From computer simulation, the results show that two LEDs used with reflector has 29.9 % larger coverage area than one LED.
