Abstract

More than 15 years of research in physical layer techniques for LED-based visible light communication (VLC) has provided the fundamental solutions to develop VLC attocell networks. In 2011, Professor Harald Haas from University of Edinburgh termed this type of network as light fidelity (LiFi). Compared to state-of-the-art RF small cell solutions, LiFi can use the low cost lighting infrastructure to achieve magnitudes of higher data rates with high level of security. In addition, the conventional RF system is compatible with LiFi since they work on different spectrum and do not generate interference with each other, and this enables the LiFi/RF hybrid network. This novel hybrid network is capable of providing ubiquitous coverage with high system throughput, and also results in a large increase of the number of servable users, which offers a potential communication solution for the Internet of Things (IoT). In this presentation, the results of the P2P LiFi communication experiment in LiFi Research and Development Centre, the University of Edinburgh, is initially shown. Following that, the studies on user multiple access, SINR performance evaluation, interference management and system load balancing in LiFi networks will be presented.
