He is currently a Principal Research Engineer and a Project Lead at Samsung Electronics R&D Institute UK. He has contributed to and later led mobile communication research, standardisation, and product development activities. While at Samsung, he has participated in flagship EU projects mmMAGIC, ONE5G and 5G LOCUS as a work package leader. He is actively contributing to 3GPP RAN1 and SA2 standardisation topics, securing vital IPR. He has filed around 50 patents to date and has also published extensively in leading conferences and journals, receiving the best paper award at the World Telecommunications Congress (WTC) in 2012.Justin P. Coon received his PhD in Communications from the University of Bristol, UK in 2005. From 2004 until 2013, he held various technical and management positions at Toshiba Research Europe Ltd. (TREL). Professor Coon also held a Reader position in the Department of Electrical and Electronic Engineering at the University of Bristol from 2012 until 2013. In 2013, he took a faculty position at Oxford University with a Tutorial Fellowship at Oriel College. Professor Coon is a Fellow of the Institute of Mathematics and Its Applications (FIMA) and a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE).Ben Allen completed his PhD degree at the University of Bristol in 2001. He completed a Royal Society Industry Fellowship with the University of Oxford and Network Rail, and has led several R&D activities involving telecoms for railways, several of which exhibit state-of-the-art advances. He is now working in the satellite communications industry. He has published numerous papers and several books on radio and telecommunications research developments. Dr Allen is a Chartered Engineer, Fellow of the Institution of Engineering & Technology, Institute of Telecommunications Professionals and the Higher Education Academy.Tony Vernon graduated from the University of Glasgow, UK, in 1987 with a Joint Honours in Electronic Engineering with Physics. After a few years in the cellular industry, he obtained chartered status and in 2002 received a PhD in Mobile Telecoms from the University of Bristol, UK. His main interests and career contributions lie in the planning and optimisation of digital mobile networks ranging from the dawn of 2G in 1991 to 5G in 2021. Dr Vernon's focus has moved to the vehicular channel (V2X) and the future use of soon-to-be-ubiquitous mobile broadband networks for national and public-access broadcasting. He is based on the Scottish Outer Hebridean island of South Uist and is passionate about expanding 4G and 5G mobile broadband connectivity to rural and remote areas.
