Keynote Talks


Prof. Harald Haas

The University of Edinburgh

Title: LiFi Attocell Networking - Taking the Small Cell Concept to a New Level

Abstract: This talk will clarify the difference between visible light communication (VLC) and Light-Fidelity (LiFi). In particular, it will show how LiFi takes VLC further by using light emitting diodes (LEDs) to realise fully networked wireless systems. Synergies are harnessed as luminaries become LiFi attocells resulting in enhanced wireless capacity providing the necessary connectivity to realise the Internet-of-Things (IoT), and contributing to the key performance indicators for the 5th generation of cellular systems (5G) and beyond. The talk will address key technologies from LiFi components to hybrid LiFi/Wireless-Fidelity (WiFi) networks to illustrate that LiFi attocells are not a theoretical concept any more, but at the cusp of real-world deployment. The talk will conclude with remarks on commercialization of LiFi technologies.

Bio: Professor Harald holds the Chair for Mobile Communications at the School of Engineering, and is the Director of the Li-Fi Research and Development Centre. Professor Haas has been working in wireless communications for 20 years and held several posts in industry. He was an invited speaker at TED Global in 2011 where he demonstrated and coined ‘LiFi’. Li-Fi was listed among the 50 best inventions in TIME Magazine 2011. Moreover, his work has been covered in other international media such as the New York Times, BBC, MSNBC, CNN International, Wired UK, and many more. He is initiator, co-founder and chief scientific officer (CSO) of pureLiFi Ltd. Professor Haas holds 31 patents and has more than 30 pending patent applications. He has published 300 conference and journal papers including a paper in Science Magazine. He published two textbooks with Cambridge University Press. His h-index is 43 (Google). In 2015 he was co-recipient of three best paper awards including the IEEE Jack Neubauer Memorial Award. He is CI of programme grant TOUCAN (EP/L020009/1), and CI of SERAN (EP/L026147/1). He currently holds an EPSRC Established Career Fellowship (EP/K008757/1). In 2014, Professor Haas was selected as one of ten EPSRC RISE Campaign Leaders.



Prof. Gerd Ascheid

RWTH Aachen University

Title: The cost of information: How many bits per processing energy?

Abstract: Power efficiency and bandwidth efficiency are two of the most important and well-known performance parameters for communication systems. Additionally, in particular for high data rates, processing energy efficiency has emerged to be another key performance criterion. The talk briefly reviews the relevant technology parameters and their evolution. In this context, it then addresses the question of achieving a proper trade-off between communication efficiency and processing efficiency.  Moreover, the talk highlights how the right approach provides surprising and relevant insights into the optimization of communication system architectures. In this regard, advanced MIMO receiver processing and wireless communication system architectures for ultra-high data rates are reviewed in more depth.

Bio: Gerd Ascheid co-founded a start-up, which successfully brought a system simulation tool to the market. After acquisition of the start-up by Synopsys Inc., Gerd Ascheid worked in the Silicon Valley based EDA market leader for 9 years as Director/Senior Director. During this time, he was responsible for ASIC design projects for advanced wireless communication systems, including DVB, 3G, and microwave radios. Since 2003, Gerd Ascheid is a full professor in the Institute for Communication Technologies and Embedded Systems at RWTH Aachen University. Gerd Ascheid has co-authored three books, published more than 250 conference and journal papers in the domains of digital communication algorithms, signal processing and ASIC implementation. He is co-founder of several successful start-up companies, the most recent being active in the Smart City domain.
