Overview of Light Fidelity

Abstract

Li-Fi is one of the recent and encouraging technologies which is used for short range and high speed data transmission. Li-fi is a segment of VLC (visible light communication which is customarily executed using white light emitting diode (LED) glowing bulbs. The VLC’s are normally implemented for lightning and gleaming by applying animmutable current terminated by LED. Although, by sporty and subtle variation of current, the observed output probably produced to fluctuate at exceedinglyexpeditious speeds. Light fidelity is a cordless optical networking mechanization whichmanipulate light emitting diodes (LEDs) for data and informationcommunication. In this project a beneficial transmission and reception is done by using a VLC system where the evolution is done under the effect of natural light. When the transmission is done, the modulation amplifier enhances the data signal for clear and longer data transmission. The effect of transmission distance with respect to the optical power, photosensitivity is detected. The transmission and reception of data is done in this project by using amplitude, modulation and demodulation technique.
