Utmost of
the bias use wireless communication to pierce internet for participating data, this has unfortunately led to an increase in network complexity, deficit of wireless radio bandwidth and an increased threat of hindrance of radio frequentness. Li-Fi technology is used to transmit the data signals using visible light as medium by using light- emitting diodes (LEDs). Signals are transmitted from one system to another by using LED as a Li-Fi transmitter and photodiode (usually solar panel) as a Li-Fi receiver for effective transmission of information. This is a much more secure system of transmission compared to being technologies. Visible Light Communication (VLC) has increased extraordinary enthusiasm for the most recent decade because of the quick advancements in Light Emitting Diodes (LEDs) manufacture. Acceptability, durable and long-life expectation of LEDs make them a promising private lighting tackle and also an option seedy and quick information exchange gear. Also, the data transmission rate is veritably high around many Gbps. This design describes and implements the design of Li-Fi audio transmission system.
Key Words: Light Fidelity (Li-Fi); Wireless Fidelity (Wi-Fi) bandwidth; Visible Light Communication (VLC); Light Emitting Diode (LED); Amplifier; Data transfer.
1. INTRODUCTION Li-Fi is shortened asâ Light Fidelityâ is recent advancement used for numerous operations like road light control, data communication, navigation for eyeless people and audio transmission etc. In this paper, an attempt is achieved to transmit audio, data and controlling the bias. In this paper, by using the visible light, pc to pc communication is achieved and controls the bias as well as audio transmission like music player to play the song is done. The father of Li-Fi is âHarald Hassâ. He innovates the idea of Li-Fi in 21st century and he say that the main thing of this invention is present in power and capacity of LEDs. Through the light we can control the bias like home accoutrements, any electronic bias can be ON and OFF by exercising the switches. As an ever-adding number of bias coming up step by step still the Li-Fi is more effective and profoundly secured and constantly transmit sound, voice in simple light force. It works in road to- vehicle communication in outside operation so it's designed in such a way that it has to transmit the data same as Wi-Fi but security and speed must be further than Wi-Fi. Li-Fi also controls the bias and spare the vitality applications and sitting in one place to control every bias in home. So, this technology is also used in home robotization operations. The data communication without network is little complicated so this Li-Fi transmits the data without any redundant networks. In airplanes, such a large number of lights are used and Wi-Fi canât be adequately employed so to overcome this issue Li-Fi can be used. The main advantage of Li-Fi is it's ok for people since light, not at all like radio frequency, canât enter mortal body. Therefore, worries of cell change are relieved. 1.1 LIFI MODULE Light Fidelity (Li-Fi) is a bidirectional, high- speed and completely networked wireless communication technology analogous to Wi-Fi. Visible light communication and a subset of optic wireless dispatches (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or indeed a relief in surrounds of data broadcasting. It's line and uv visible-light communication or infrared and near-ultraviolet rather of radio- frequency diapason, part of optic wireless dispatches technology, which carries much further information, and has been proposed as a result to the RFbandwidth limitations. Visible light dispatches (VLC) works by switching the current to the leds out and on at a veritably high rate, too quick to be noticed by the mortal eye. Although Li-Fi leds would have to be kept on to transmit data, they could be bedimmed to below mortal visibility while still emitting enough light to carry data. The light swells cannot access walls which makes an
