PLENARY SESSIONS : MONDAY, September 16 MAPI1 The Brave New Wireless World 9:20 - 10:10 Tagus Room Dr. João Schwarz da Silva European Commission, Belgium Abstract Europe benefits today from a unique technological and industrial leadership in the mobile and wireless communications field, thanks in particular to the European Union's R&D Programmes. Critical mass of RTD, together with a consensus building approach, an early identification of the spectrum requirements and a close articulation with policy objectives, have led to the establishment of European standards which are today adopted by a majority of countries world wide. As we move beyond 3G systems, the question is raised as to what the future has in stock for wireless and mobile communications. On one hand, the ever increasing microprocessor cost/performance ratios, the availability of efficient, smart power sources and low-power displays, wearable multimedia devices, onboard computing systems, nano sensors and the miniaturisation of body implants, promises to extend wireless connectivity, and foster the emergence of a tight grid of body and personal area networks. On the other new perspectives are being opened concerning the optimised delivery of context-aware multimedia services across a range of heterogeneous wireless systems and networks, including notably broadcasting networks. Playing an increasingly important role are the concepts of reconfigurability which entail the pervasive use of "software re-definition" allowing (possibly live) upgrades/patching of any element of a wireless network, and of all services and applications running on it. With the launch of the 6th Framework Programme of R&D, the European Union seeks to address the multiple challenges of the 4th Mobile and Wireless Generation. New opportunities will be provided to the research community to participate in the development of the future wireless landscape. Short biography of the speaker João Schwarz da Silva received a PhD on the Performance Analysis of Mobile Packet Radio Systems from Carleton University, Ottawa, Canada in 1982. After several years with the Industry Canada and the International Telecommunications Union, where he worked respectively in spectrum management and HF frequency planning, he joined the European Commission in 1991 and is currently Head of Mobile, Personal and Satellite communications, in the context of the European Union's R&D Programme. His area of work covers terrestrial and satellite based wireless systems and networks including 2G, 3G, MBS and Wireless LAN's, interactive broadcasting, reconfigurable networks, broadband satellite communications and advanced mobile services and applications. He is the author of some 50 papers and has been invited as guest editor of IEEE Communications and Personal Communications Magazine. MAPI2 4G Network Architectures: WLAN Hot-Spots, Infostations and Beyond 10:40 - 11:30 Tagus Room Prof. Dipankar Raychaudhuri Rutgers University, USA Abstract This talk will discuss potential architectures for future "4G" wireless networks, recognizing the need for systems that exploit the capabilities of multiple radio technologies including WCDMA, WLAN (802.11, Hiperlan), Bluetooth, UWB, etc. We outline an IP-based, open-architecture mobile network that supports efficient interworking between multiple radio access technologies, as required in future service scenarios such as 3G/WLAN "hot-spots" and "Infostations". In conclusion, we look ahead to even more scalable wireless systems (for pervasive computing, sensor networks, etc.) based on emerging self-organizing ad-hoc networking concepts. Short biography of the speaker Dipankar Raychaudhuri is currently Professor, ECE Dept & Director, WINLAB (Wireless Information Network Lab) at Rutgers University. Prior to this, he was Chief Scientist at Iospan Wireless (2000-01), Assistant General Manager & Dept Head (Systems Architecture) at NEC USA, C&C Research Laboratories (1993-99) and Head, Broadband Communications Research at Sarnoff Corp (1990-92). Dr. Raychaudhuri obtained his PhD (EE) and MS(EE) degrees from SUNY, StonyBrook (1979, 78) and the B.Tech (Hons) from IIT Kharagpur (1976). He is a Fellow of the IEEE. MAPI2 From 3G to 4G: Technical Challenges for Systems Beyond IMT-2000 11:30 - 12:20 Tagus Room Dr. Kota Kinoshita NTT DoCoMo, Japan Due to last minute impairment, Dr. Kota Kinoshita's talk will be delivered by Dr. Yasushi Yamao, Vice-President and Senior Director, Wireless Laboratories, NTT DoCoMo, Japan Abstract The IMT-2000 3rd generation mobile communication system (3G) was launched in Japan in 2001 and will be introduced worldwide. The system provides a variety of mobile multimedia communication services through its high-speed transmission and wide-area coverage capability. On the other hand, broadband access in fix networks and wireless LANs are gaining popularity, and they are driving mobile communications toward broadband and lower cost. Furthermore, growing demand for mobile multimedia services including mobile Internet will result in a remarkable increase in mobile communications traffic. The fourth generation mobile communication system (4G), or the Systems Beyond IMT-2000, is expected to provide significantly higher performance and flexibility with lower bit-cost than that of IMT-2000. Current technical challenges to future systems will be presented with a view on the required characteristics. Short biography of the speaker Dr. Kota Kinoshita received his B.S.E.E. and M.S.E.E. degrees from Keio University, Tokyo, in 1969 and 1971, respectively. He received his D.S.E.E. degree from Keio University in 2000. In 1971, he joined the Electrical Communication Laboratories, Nippon Telegraph and Telephone Public Corporation (NTT), Japan, and in 1992 he transferred to NTT Mobile Communications Network, Inc. (NTT DoCoMo). Since 1971, he has been engaged in the research and development of mobile communications systems. During this period, he engaged in the research and development of the mobile station, radio infrastructure equipment, and system design for NTT analog systems. Subsequently, he became the leader of the development for the PDC system and standardization in Japan. He is also responsible for managing the standardization and development for W-CDMA. He is now an Executive Vice President and the Chief Technology Officer of NTT DoCoMo, Inc.
