Visible Light Communication

Ayush Sharma ^[3] | Sugandha Bajaj | Sonia Ahlawat

Abstract: Visible Light Communication (VLC) is a new and safer way of transmitting data using visible light spectrum (375nm-780nm). It allows a comparatively safer data transfer and uses a safer spectrum than radio spectrum which is being used at present times. LED lights which are used widely in our day to day life because of their low cost and luminous competence are used for the data transmission in VLC. Transmission of data takes place through visible light LEDs at transmitter end and reception takes place using Photodiodes or Photoreceptors at the receivers end. While using Wi-Fi (wireless fidelity), sometimes there occurs a problem of slow speed when more than certain devices are tapped into the network, as a result of shortage of bandwidth. To overcome this, light is used to transfer data (audio signals in case of this paper) which is known as DATA TRANSFER THROUGH ILLUMINATION. In this paper, visible light communication is used to transfer audio signals using LEDs.
