Global ICT Outlook

Monday 19 May 2014, 9:00–10:00 (Ballroom)

Dr. Jae W. Byun, CTO SK Telecom

Due mainly to the technological evolution and the rise of innovative ideas, the ICT ecosystem is evolving rapidly from its traditional 'Content – Platform – Network – Device' value chain, as 'convergence with neighboring industries' is becoming a new major trend. Smartphone has been the main driving force and the vanguard of such change. With the saturation of high-end Smartphone market, what used to be a competition of devices and OS capability is slowly turning into a competition of service innovation and next-gen devices.

In 2014, the global ICT market is expected to face six key trends in service innovation and next-gen devices. Trends in service innovation are the
(1) Rise of communication services by Apple and Google,
(2) Booming of context-aware personalization services, thanks to the improvements in personalization S/W and situational awareness sensors,
(3) Beginning of online-offline smart shopping services initiated by Apple's iBeacon technology and
(4) Expansion of media platform alliances for market leadership, as well as strengthening of media strategy by Apple and Google.

Trends in next-gen device are
(5) Apple’s entrance into Smart Vehicle ecosystem with CarPlay, and
(6) Competition in wearable devices is not as independent devices, but as supplementary devices for Smart phones.

In the Network industry, LTE is expanding around the world to become a mainstream service, and discussions about 5G are just about to start. Previous network evolution from 1G to 4G were initiated by technological development creating generation gaps. Another such breakthrough is expected for 5G evolution, but current advancement in telecommunication technology makes it difficult to predict where such breakthrough would take place. Based on previous experiences, Small Cell is being considered as one of the potential breakthrough technologies in reaching a 1000x capacity increase by 2020.

Dr. Byun is currently the CTO of SK Telecom, and Chairman of Next Generation Mobile Network Alliance. He has over 20 years of experience in the telecommunication and information technology industries. Since he joined SK Telecom in 1993, he has held a wide range of management positions in R&D, network engineering and planning divisions. He received 'CDG Industry Leadership Awards' in 2002 for his contribution toward successful commercialization of CDMA technologies. After leading a full-fledged WCDMA commercial service launch in 2007, he was elected as a NGMN board member in 2008, and as a chairman of the board in 2012.
Dr. Byun led the LTE commercial launch in 2012, and later won 'Outstanding LTE Contribution Award' in Mobile World Congress and 'Most Significant Development of a Commercial LTE Network Award' in LTE World Summit 2013. In 2010 and 2011, he led a series of SK Group-level technology-based business development projects at SK Holdings.

5G Vision/Requirements and Key Technologies

Tuesday 20 May 2014, 9:00–10:00 (Ballroom)

Dr. Kyungwhoon Cheun , Senior Vice President Samsung Electronics

The race to search for innovative solutions to enable the Next Generation Mobile Communications (5G era) has recently begun worldwide. In early 2013, the European Commission announced that it would invest €50 million in 2013 for 5G research in multiple projects such as METIS, quickly followed by the formation of the Chinese Government-led IMT-2020 Promotion Group in February 2013, the initiation of the Korean Government-led 5G Forum in May 2013, and the formation of 2020 and Beyond Ad-hoc within ARIB (Association of Radio Industries and Businesses), Japan, in October, 2013. While the standardization of 5G specifications in standards bodies such as the Third Generation Partnership Project (3GPP) and the formal ratification of 5G standards by the International Telecommunication Union (ITU) are still several years away, many share the vision of targeting 2020 for the initial commercialization of 5G cellular with drastically enhanced user experience.
This talk presents the vision, requirements, and the key technologies envisaged for the 5G mobile communications in 2020 and beyond era. The requirements emerged for the 5G era include massive capacity with order of magnitude data rate improvement as well as uniform Gbps experience, reduced latency for delay sensitive services, massive connectivity supporting innumerable simultaneous connections, and all these demands with energy efficient as well as cost effective solutions. The talk will put forth a few key technologies ranging from air technologies and network design to services along with the recent R&D achievements proving the feasibility of the proposed technologies and showing a bright prospect of 5G.

Dr. Kyungwhoon Cheun received his B.S. in Electronics Engineering from Seoul National University in 1985. He earned is M.S. and Ph.D. degrees from the University of Michigan, Ann Arbor in 1987 and 1989, respectively. He was an assistant professor at University of Delaware from 1989 to 1991 and joined the Pohang University of Science and Technology (POSTECH) in 1991 where he is currently a full professor. At POSTECH, he headed the national ITRC center for Broadband OFDM Multiple Access (BrOMA), an 8 year research program supported by the Korean Ministry of Knowledge and Economy. Dr. Cheun has also served as an engineering consultant to numerous industry and was on leave at Witechs and NSystems in San Diego where he developed efficient receiver algorithms for the IEEE802.11 based WLANs and WCDMA. Aside from his academic duties, he served as the Chief Technical Officer (CTO) for Pulsus Technologies Inc. during 2004 to 2011, a Qualcomm partner company where he was in change or developing sound processing algorithms and sigma-delta modulation based full digital audio amplifier SoCs. Since 2012 he has been with Samsung Electronics DMC R&D Center as a senior vice president and leads the Communications Research Team in the area of next generation cellular and Wi-Fi networks.
