5G Vision, N/W Architecture & Service

Dr. Alex Jinsung Choi
CTO, EVP and Head of Corporate R&D Center, SK Telecom

Abstract: Over the past few years, one of the key buzzwords in the mobile network industry has definitely been 5G. An increasing number of mobile network operators, equipment manufacturers, research organizations and governments are actively engaged in discussions on5G and its key enabling technologies. In 2012, International Telecommunication Union (ITU) coined the term “IMT-2020” to tentatively describe 5G and announced its plan towards 5G. To be more specific, ITU plans to define 5G visions and requirements by 2015 and 2017, respectively. Then, suggestions on key enabling technologies and architecture which satisfy the defined IMT-2020 requirements will be gathered and evaluated by the second half of 2017. Based on the suggestions and evaluation results, the goal is to complete the 5G standardization by 2020. In accordance with this timeline, many countries and regions around the world have established organizations tasked with better defining 5G services and infrastructure, while exchanging their intermediate views and technologies. Especially in South Korea, 5G development is also high on the national agenda because of the looming 2018 Winter Olympics. This talk describes SK Telecom’s vision, requirements, network architecture and service on 5G as the most front-runner operator worldwide.

IC chips to be dependable, secure, and robust

Prof. Makoto Nagata
Graduate School of System Information, Kobe University, Japan

Abstract: An IC chip needs to be dependable, secure, and robust in designs for automotive, aviation, medical, and many other critical applications. The dependability of an IC chip features the tolerance and adaptability to environmental disturbances such as electromagnetic fields. The security of an IC chip relies on such as the hardware trust and tamper resistance. The robustness is generally required, but technically covered by the integrity in design and the testability and diagnosis in fields. This talk addresses challenges in the design of an IC chip to cope with those versatile characteristics from different physical origins, while meeting the specified functionality and performance of circuits.


Makoto Nagata received the B.S. and M.S. degrees in physics from Gakushuin University, Tokyo, Japan, in 1991 and 1993, respectively, and the Ph.D in electronics engineering from Hiroshima University, Japan, in 2001. He was a research associate at Hiroshima University, Japan, from 1994 to 2002, and then an associate professor of Kobe University, Japan, from 2002 to 2009. He is currently a professor of the graduate school of system informatics, Kobe University.

His research interests include design techniques toward high performance mixed analog, RF, and digital VLSI systems with particular emphasis on power/signal/substrate integrity and electromagnetic compatibility, testing and diagnosis, three dimensional system integration, as well as connectivity and security applications. He was a co-recipient of the best paper awards from 3D-Test 2013 and CHES 2014.

Dr. Nagata has been a member of a variety of technical program committees of international conferences such as the Symposium on VLSI Circuits (2002-2009), Custom Integrated Circuits Conference (2007-2009), Asian Solid-State Circuits Conference (2005-2009), International Solid-State Circuits Conference (2014-), and many others.

From Eros (Silicon) to Gaia (Storytelling Business) over 5G

Dr. Byung K. Yi
InterDigital’s Executive Vice President, InterDigital Labs, and Chief Technology Officer

Abstract: Commonly acceptable modern industrial revolutions would be marked by analog to digital conversion kindled by semiconductor (Si), dedicated main frame computer to distributed personal computers, isolated intra network to internet, and fixed telecom to mobile wireless communications. This presentation will be a non-linear and non-traditional, in some senses not strictly talking about technology-and-service trends of future wireless technologies beyond 4G. During 4G developments, every corners of the technology carpet have been turned over looking for 0.2-0.5 dB improvements in bandwidth efficiency and throughput. In this talk, we will drive through the newly paved wireless mobile broadband highway with the storyteller’s views, which mainly relied on human perceptions and/or emotional motivations of the individual. Technology, device, and service trends will be reviewed briefly. The realistic and readily achievable mobile multi-media mess markets will be suggested. Before draw the conclusions, the presentation will explore some of the current research topics which are under development for 5G.
