Keynote Topic - Evolution to 5G Wireless for Personalized Cloud and Communications Services


With 1,000 times higher data rates and more flexible spectrum use as compared with current 4G LTE systems, 5G wireless aims at delivering one gigabyte of mobile data for everyone daily by 2020. The challenge is not just delivering one gigabyte per user per day, but personalizing every bit and being profitably. Smart phones play the key role as the gateways to the cloud and the bridges of multiple sensors, and can teach networks to be cognitive. Software defined networking (SDN) enables telecom operators to provide personalized network experiences to each individual in an efficient manner. In this talk, we will discuss the opportunities, challenges, and solutions of broadband wireless communications in the era of cloud computing for providing human-centric cloud and communications services.


Dr. Li-Chun Wang received the B.S. degree from National Chiao Tung University , Taiwan, R. O. C. in 1986, the M.S. degree from National Taiwan University in 1988, and the Ms. Sci. and Ph. D. degrees from the Georgia Institute of Technology , Atlanta, in 1995, and 1996, respectively, all in electrical engineering.

From 1990 to 1992, he was with the Telecommunications Laboratories of the Ministry of Transportations and Communications in Taiwan (currently the Telecom Labs of Chunghwa Telecom Co.). In 1995, he was affiliated with Bell Northern Research of Northern Telecom, Inc., Richardson, TX. From 1996 to 2000, he was with AT&T Laboratories, where he was a Senior Technical Staff Member in the Wireless Communications Research Department. Since August 2000, he has been an Associate Professor in the Department of Communication Engineering of National Chiao Tung University in Taiwan. His current research interests are in the areas of adaptive/cognitive wireless networks, radio network resource management, cross-layer optimization, and cooperative wireless communications networks..

Dr. Wang was elevatated to be IEEE Fellow in 2010 for his contributions in cellular architecutures and radio resource management techniques in wireless networks. He was a co-recipient (with Gordon L. Stuer and Chin-Tau Lea) of the 1997 IEEE Jack Neubauer Best Paper Award for his paper "Architecture Design, Frequency Planning, and Performance Analysis for a Microcell/Macrocell Overlaying System," IEEE Transactions on Vehicular Technology, vol. 46, no. 4, pp. 836-848, 1997 (best systems paper published in 1997 by the IEEE Vehicular Technology Society). He has published over 150 journal and international conference papers and is holding three US patents . He served as an Associate Editor for the IEEE Trans. on Wireless Communications from 2001 to 2005, the Guest Editor of Special Issue on "Mobile Computing and Networking" for IEEE Journal on Selected Areas in Communications in 2005 and on "Radio Resource Management and Protocol Engineering in Future IEEE Broadband Networks" for IEEE Wireless Communications Magazine in 2006. He is holding 8 US patents. His recent reseach interests are in coginitiv radio, energy-efficient wireless system, heterogeneous cross-network design, and cloud computing for mobile applications.

The UberCloud HPC Experiment - Paving the way to High Performance Computing as a Service in the Cloud


There are several million of small and medium-size manufacturers around the world, most of them using workstations for their daily design and development work. However, there is often the need for more computing. Buying an expensive compute cluster is usually not an option, and renting computing power from the Cloud still comes with severe roadblocks, such as the complexity of the applications and their implementation itself, intellectual property and sensitive data, expensive data transfers, conservative software licensing, performance bottlenecks from virtualization, user-specific system requirements, and missing standards and lack of interoperability among different clouds.

On the other hand, the benefits of using remote computing resources are extremely attractive: no lengthy procurement and acquisition cycles; shifting some budget from capex to the more flexible opex; gaining business flexibility by getting additional resources on demand, at your finger tip; and scaling resource usage automatically up and down according to your actual needs.

Thus the UberCloud Experiment has been designed to reduce many of the barriers mentioned above. By participating and moving the engineering application onto a remote computing resource, end-users can expect a long list of real benefits, such as: UberCloud is vendor neutral; no hunting for resources in a crowded Cloud market; professional match-making of end-users with suitable service providers; free, on-demand access to hardware, software, and expertise during the experiment; carefully tuned end-to-end, step-by-step process to accessing remote resources; learning from the best practices of other participants; no-obligation, risk free proof-of-concept: no money involved, no sensitive data transferred, no software license concerns, and the option to stay anonymous. With these benefits, the experiment is leading the way to increasing business agility, competitiveness, and innovation, and participants are not getting left behind in the emerging world of Cloud Computing. Last but not least, all participants are encouraged to make use of the interactive UberCloud Exhibit, a directory of professional cloud services to the wider CAE, Life Sciences, and Big Data communities.

This keynote presentation with present all the aforementioned topics in further detail and provide some real SME use cases.


Prof. Wolfgang Gentzsch is consultant for HPC, Grid and Cloud; Co-founder of the UberCloud Experiment together with Burak Yenier; Advisor to the EU funded project EUDAT; and the Chairman of the ISC Cloud Conferences. Previously, he was an Advisor to the EU project DEISA, directed the German D-Grid Initiative, and was a member of the Board of Directors of the Open Grid Forum, and of the US President's Council of Advisors for Science and Technology, PCAST. Before, Wolfgang was a professor of computer science and mathematics at several universities in the US and Germany, and held leading positions at the North Carolina Grid and Data Center in Durham, Sun Microsystems in California, the DLR German Aerospace Center in Gottingen, and the Max-Planck-Institute for Plasmaphysics in Munich. In the 90s, he founded HPC software companies Genias and Gridware, the latter developing what is now Grid Engine.

How to Build Cloud-based Mobile Network for Enterprise


A CDMA network consists of a radio network and a core network. The radio network includes BTS (Base Transceiver System) and BSC (Base Station Controller). A typical core network includes at least one MSC (Mobile Switching Center) and one HLR (Home Location Register). The core network equipments are expensive. To offset high cost of core network, operators need to install many BTS and BSC to increase the coverage and subscribers. This forces an entrepreneur to pay entry price of at least $1 million to become a CDMA operator, this entry price leaves no business sense to set up CDMA network for some enterprises, is there an alternative?

Confederal Networks provides a revolutionary way to build CDMA network. Start with isolated fixed wireless local loop points, operators can escalate their network into the next level, ROAMING, as more and more wireless local loop points keep being added, operators can turn wireless local loop into standard IS41 network by adding MSC and HLR. The Mobility Manager's hardware is re-used by MSC. The local IP PBXs are converted into small media gateway.


Prof. Roy “Xiaorong” Lai is the co-founder and Chairman of Confederal Networks Inc, one of the leading mobile network providers for enterprises with its headquarter in Seattle, WA. Together with his team, he successfully designed and commercialized the world first CDMA mobile network for coal mines. He also serves as the chief expert of China Coal Automation Research Institute and a Distinguished expert of Ningxia Hui Autonomous Region, China, and the adjunct/guest professor of Chinese Academy of Sciences, Beijing University of Posts and Telecoms, etc. After he became the Managing Director of R&D Department of Concord Telecom in 1993, he has over 20 years of high-ranking leadership experience in telecom industry. He was ranked No.4 among the 2004' Top 10 Telecom People in China. He is an IEEE senior member.
