Mobile Communication Evolution
Speaker: Toshio Miki, Managing Director of Communication Device Development Department, NTT DoCoMo Inc., Japan
Abstract :
With the growing demand for high-speed and high-capacity data transmission in mobile communications, DoCoMo launched 3rd generation (3G) cellular services "FOMA" with the maximum data rate of 384 kbps in 2001. DoCoMo proposed the "Super 3G concept" as the long-term evolution of 3G after the global deployment of 3G. This is because the long-term evolution of 3G is constitutive for 3G system to keep a highly competitive position. Super 3G also enables a smooth migration path towards 4th generation (4G) aiming at the target data rate; e.g. 100 Mbps at high mobility and 1 Gbps at low mobility.

Besides higher data rate, future mobile services will promote a ubiquitous communications environment in which all kinds of devices and objects are interconnected to attain real space and virtual space interaction. They are expected to facilitate the development of the so-called "mobile ubiquitous world". In a mobile ubiquitous world, all kinds of things will be interconnected as needed to form ubiquitous networks that should arise frequently and simultaneously while changing continuously.

This speech presents the current status of the 3G services, views on the migration scenario from 3G to 4G, and research activities for achieving 4G services and mobile ubiquitous world.

Toshio Miki is the Managing Director of Communication Device Development Department, NTT DoCoMo Inc. since July 2006. Mr. Miki was born in Osaka, Japan, on March 5, 1956. He received the B.S. and M.S. degrees in electronics engineering from Kyoto University, Kyoto, Japan, in 1978 and 1980, respectively. Since 1980, he has been with the Research Labs. of NTT and NTT DoCoMo. He was a residential researcher of AT&T Bell Labs. in 1988. From 1999 through 2003, he was the founding President & CEO of DoCoMo Communications Laboratories USA Inc. After that, he was the managing Director of Multimedia Labs. in 2004, and Wireless Labs. in 2005.
 From 1977 to 1984, he was engaged in the research of digital mobile communication technologies, in particular, modulation/demodulation and diversity reception. He started the research of speech coding in 1985, aiming for PDC (Japanese Digital Cellular Systems). His proposal, PSICELP, was standardized and widely used as PDC half-rate speech codec. He extended his research field to audio-visual coding in 1994, such as MPEG-4 and relevant ITU-T standards.
 He had been a member of ARIB STD-27 CODEC WG from 1991 through 1995 for the work of PDC half-rate speech coding standardization.
 From 1995 through 1999, he served as the MPEG-4 subcommittee chairman of Japanese National Body. He also served as the Co-Chairman of the Video Verification Tests Ad-Hoc Group and the Audio Error Resilience Ad-Hoc Group in MPEG.
 From 2002 through 2004, he was a trustee of ISOC (Internet Society).
 Mr. Miki was awarded the IEEE Vehicular Technology Society Paper of the Year and the IEICE young engineers award in 1984. He received the Achievement Award of IEICE in 1992. He is a senior member of IEEE, and a member of IEICE of Japan, IPSCJ, and ISOC.

New Avenues for Microwave Component Design
Speaker: Tatsuo Itoh, Professor of UCLA, U.S.A.
Abstract :
This talk will present a subjective view for emerging microwave component and circuit designs deviating from traditional approaches. First, a trend started about 10 year ago is a global design in which active device characterizations are combined with passive circuit and electromagnetic analysis. Second and more recent trend is to take into account the propagation aspects of the communication channel into hardware design. The third is the dispersion engineering recently coming to greater recognition by the emergence of metamaterials.

Tatsuo Itoh is Professor of Electrical Engineering and holder of the Northrop Grumman Endowed Chair in Microwave and Millimeter Wave Electronics at UCLA. He is a Fellow of the IEEE, served as the Editor of IEEE Transactions on Microwave Theory and Techniques, President of the MTT Society and Editor-in-Chief of IEEE Microwave and Guided Wave Letters. He was elected as an Honorary Life Member of MTT Society in 1994. He received a number of awards including IEEE Third Millennium Medal and IEEE MTT Distinguished Educator Award. He is a member of National Academy of Engineering. He has over 1000 publications and generated 65 Ph.Dfs.
