Prof. Harald Hass

We will start by clarifying the differences between visible light communications (VLC) and LiFi. This is followed by the introduction of the key building blocks required to create full LiFi networks. Next we report recent key achievements of the UP-VLC project with respect to component and demonstrator developments underpinning LiFi attocellular networks. We provide modelling results of such networks and address numerous misconceptions such as  "LiFi is a line-of-sight technology". The talk also addresses the issue of energy efficiency of optical attocell networks and showcases how off-the-shelf solar panels can fulfill two functions at the same time, i) energy harvesting and ii) LiFi data detection. The talk closes by summarizing commercialization challenges.

Professor Harald Haas received the Ph.D. degree from the University of Edinburgh, Edinburgh, U.K., in 2001. He is currently the Chair of Mobile Communications at the University of Edinburgh, and is the Founder and Chief Scientific Officer of pureLiFi Ltd, Edinburgh, U.K., and the Director of the LiFi Research and Development Center, University of Edinburgh. His main research interests include optical wireless communications, hybrid optical wireless and RF communications, spatial modulation, and interference coordination in wireless networks. He first introduced and coined spatial modulation and LiFi. LiFi was listed among the 50 best inventions in TIME Magazine 2011. He was an Invited Speaker at TED Global 2011, and his talk: Wireless Data from Every Light Bulb has been watched online more than 2.4 million times. He gave the second TED Global lecture in 2015 on the use of solar cells as LiFi data detectors and energy harvesters which was viewed online more than 1.7 million times. He holds 43 patents and has more than 30 pending patent applications. He has published 400 conference and journal papers including a paper in Science. He coauthors a book entitled: Principles of LED Light Communications Towards Networked Li-Fi (Cambridge Univ. Press, 2015). He was a co-recipient of recent Best Paper Awards at the IEEE Vehicular Technology Conference (VTC-Fall) in Las Vegas in 2013, and VTC-Spring in Glasgow in 2015, ICC 2016 in Kuala Lumpur and ICC 2017 in Paris. He was a co-recipient of the EURASIP Best Paper Award for the Journal on Wireless Communications and Networking in 2015, and a co-recipient of theJack Neubauer Memorial Award of the IEEE Vehicular Technology Society. In 2012, he received the prestigious Established Career Fellowship from the Engineering and Physical Sciences Research Council within Information and Communications Technology in the U.K. He received the Tam Dalyell Prize 2013 awarded by the University of Edinburgh for excellence in engaging the public with science. In 2014, he was selected by EPSRC as one of ten Recognizing Inspirational Scientists and Engineers Leaders in the U.K. In 2016 he was recipient of the Outstanding Achievement Award of the International Solid State Lighting Alliance (ISA), and 2017 he was elected Fellow of the Royal Society of Edinburgh.
