Visible light communication

VLC physical layer techniques have advanced significantly during last decade. We have seen tremendous improvements in data rates, range and coverage. Novel devices such as SPADs and micro LEDs can improve VLC systems considerably. VLC is not just a point-to-point communication technology. Li-Fi attocellular networks achieves ever smaller cells to enable 10,000 more traffic, 100 times more wireless devices and peak data rates above 10 Gbps. Li-Fi enables secure wireless communications. Li-Fi is a strong candidate for 5G technology. Li-Fi supports the emerging Internet-of-Things as well as new ways of energy harvesting wireless communications.
