Continuous improvements in wireless communication systems, e.g. 3G, 4G, etc.., require higher bandwidth and due to the lack of sufficient Radio Frequency spectrum, we should adopt a wireless system which will support wide bandwidth. So the new technology of Li-Fi came into the aid. Light fidelity (Li-Fi) is a new short range optical wireless communication technology which provides data transmission like text, audio, video by using Light-Emitting Diodes (LEDs) to transmit data depending on light illumination properties.It uses the visible light spectrum which is 10,000 times larger than the entire radio frequency spectrum [1]. In this technology, LEDs are used to transmit data in the visible light spectrum. Lasers can also be used instead of LED but it requires proper alignment between the transmitter and receiver. This technology can be compared with that of Wi-Fi and offers advantages like increased accessible spectrum, efficiency, security, low latency and much higher speed. Communication is achieved by switching LED lights or laser on and off at a data speed higher than what is perceptible to the human eye.This concept promises to solve issues such as the shortage of radio-frequency bandwidth and boot out the disadvantages of Wi-Fi. Li-Fi is the upcoming and on growing technology acting as competent for various other developing and already invented technologies. Hence the future applications of the Li-Fi can be predicted and extended to different platforms and various walks of human life.
