Abstract: Usage of light emitting diode (LED) is rapidly growing due to its reliability, low power consumption and high efficiency. Visible light communication (VLC) technique using white light emitting diode (LED) is a promising technology for next generation short range communication and high speed wireless data transmission. In this paper, indoor Light Fidelity (Li-Fi) Transceiver for Data Transmission is designed and System model considers the Position of light - emitting diodes (LEDs) as well as the detectors.The transceiver is able to transferData like "Character – Text Files – photo – audio" through modulated LED light beam using OOK modulation technique. This transceiver proposedplatform software that we developedto be able to upload the required data .abase 64 coding process is performed then the coded data is transmitted via LEDs. The coded data is received via photo transistor at receiver side and then decoded to be returned to its original form. A simulation program written in MATLAB is used also to plot the distributions of illuminance and the transmitted powers calculated mathematically according to data sheet of LED.
