报告摘要:

WiBro is a 2.3 GHz based Mobile WiMAX system that realizes the IEEE 802.16e standards. WiBro system was developed very recently and is currently being deployed for commercial services for the first time. The Mobile WiMAX/WiBro system distinguishes itself by the three distinctive features, namely, broadband, IP and mobility. It provides high-speed data services over 19/5Mbps downlink/upling in its initial stage, which is likely to be doubled in the second stage. It fully employs the IP technology, differently from the existing circuit-mode cellular systems such as WCDMA/HSDPA and cdma2000/EV-DO. In addition, it can provide high-rate data services to the mobile users moving over 120 km/h. In multiple access, it distinguished itself from the existing cellular mobile systems in that it employs the OFDMA technology, not the CDMA or TDMA technology. In this aspect, the Mobile WiMAX/WiBro system is viewed to be on the path towards the 4th generation wireless systems. The technical presentation will introduce Mobile WiMAX/WiBro in the scope of system overview, standards, system development, deployment and services. It will include illustrations of the systems that have been developed by Samsung Electronics and the trial/commercial services provided by KT since June 2007.

He served as the Editor (in chief) of the IEEE Global Communications Newsletter, an Associate Editor of the IEEE Transactions on CSVT, and the founding Associate Editor-in-Chief and the Editor-in-Chief of the Journal of Communications and Networks (JCN). He served for the IEEE Communications Society (ComSoc) as the Director of Membership Programs Development, as the Director of Asia Pacific Region, as the Director of Magazines and as a Member-at-Large to the Board of Governors. He currently serves as the Vice President for Membership Development of IEEE ComSoc, as the President of Korea Institute of Communication Sciences (KICS) and as a Vice President of the ABEEK. He is the founder and the first President of the Citizens’ Coalition for Scientific Society (CCSS), a non-government organization for the advancement of science and technology in Korea, a member of Presidential Advisory Council on Science and Technology, and a member of Presidential Advisory Committee for Policy Planning.

Dr. Lee is a co-author of Broadband Telecommunication Technology, 1st & 2nd editions, (Artech House), Scrambling Techniques for Digital Transmission (Springer Verlag), Scrambling Techniques for CDMA Communications (Kluwer), and Integrated Broadband Networks (Artech House). He holds seven U.S. patents with four more patents pending. His current fields of interest include broadband networks, wireless networks, communication systems, and signal processing.

He received the 1984 Myril B. Reed Best Paper Award, Exceptional Contribution Awards of AT&T Bell Laboratories, a Distinguished Achievement Award of KICS, the 2001 National Academy of Science (of Korea) Award, and the 2005 Kyung-am Academic Award. He is a Member of the National Academy of Engineering of Korea, a Member of Sigma Xi, and a Fellow of the IEEE.
