Li-Fi Technology: High data transmission securely

Abstract

Visible light communication (VLC) is an optical wireless communication method which transmits data through the medium of light within the visible light spectrum. The bidirectional communication through the light is called light fidelity Li-Fi. The infrastructure of such technology is already available where the light can be used for illumination and communication simultaneously. In the paper, we discuss the usage of VLC applied as Li-Fi as a secure method to transmit data wirelessly in a more secure method compared to the traditional Wi-Fi architecture. In addition, we investigate the bit-error rate (BER) performance in the VLC network based on the modulation format of Orthogonal Frequency-Division Multiplexing (OFDM) for high data transmission.
