LiFi Integrated to Power-lines for Smart Illumination Cum Communication

Visible Light Communication (VLC) system based on white LEDs has emerged as an eco-friendly IT green technology using THz visible light spectrum in provision of both lighting and wireless access. Installation of new communication cables between other fixed network (PC, Set-Top Box, fiber networks, etc.) and LED lights is expensive, disruptive and time consuming process. Meanwhile, the power-line communications (PLC) can make it possible to use the power lines as the medium of communications. The utilities of home networking over power-lines can take advantage of the existing wiring infrastructure for provision of illumination cum communication. The integrated system of VLC and PLC is a smart way of fulfilling the premise of broadband access for home networking, while providing efficient and low-cost lighting. To achieve the higher data rates (MHz), PLC channel is simulated using DMT-QAM modulation scheme.
