As per the growing demands of wireless communication, the number of devices accessing the internet has
reached a new level. A design and implementation of audio transmission that uses Li-Fi technology as a network
infrastructure is discussed here. Most of the existing system in the market uses radio waves as communication medium.
Li-Fi can be thought of as a light-based Wi-Fi. That is, it uses light instead of radio waves to transmit information. In LiFi, transceiver-fitted LED lamps which can light a room as well as transmit and receive information would be used,
instead of using Wi-Fi modems. Voice is transmitted through Li-Fi communication. The system uses a visible light
communication as an interface among electrical devices as well as people. Li-Fi communication technology uses light
frequencies rather than the usual radio waves which can produce data faster than 10 Megabits per second which is very
much efficient than our average broadband connection of Wi-Fi.
