ABSTRACT: Despite the success of cellular voice services and the explosive growth  of the Internet, wireless data services have not captured a significant market share. One of the fundamental limits is the low date rates, thus throughput, available in the current wireless systems, especially for
those of the macrocellular environments. In this talk, we will discuss the R&D, standardization and deployment efforts for the 2.5 G - 3G systems and future systems to "widen the pipe."
The focus is on the physical and medium access control layers. Detailed performance study on the TDMA systems using EDGE (Enhanced Date-rates for GSM Evolution) platform will be presented. A high-level discussion on the analogous approaches for the WCDMA (Wideband CDMA) system will also be
given. Time permitting, we will discuss an OFDM based approach for high speed data beyond 3G.

BIOGRAPHY: Dr. Chuang received the BSEE degree from National Taiwan University, Taipei, Taiwan, in 1977, and the MS and PhD degrees in Electrical Engineering from Michigan State University, East Lasing, Michigan, in 1980 and 1983, respectively.
Dr. Chuang was with GE Corporate R&D and Bellcore (now Telcordia Technologies) where he studied different aspects of wireless personal communications, including effects of delay spread, modem design, fading counter-measures,  system simulations, radio resource management and radio system prototyping.
Many of his research results have become key system specifications of the Personal Access Communications System (PACS) which is now a US PCS standard. In August 1993, he joined the Department of Electrical and Electronic Engineering at The Hong Kong University of Science and Technology where he  led to set up the Wireless Communications Research Program.  In June 1996, He returned to the US and joined AT&T Labs - Research where  he is now a Technology Consultant. He continues to serve as an Adjunct
Professor of HKUST.
Dr. Chuang is the Area Editor of Wireless Communications for the IEEE Transactions on Communications. He has also guest-edited two special  issues on Wireless Personal Communications for the IEEE Journal on Selected Areas in Communications. Since 1998, he is an Editor of the J-SAC: Wireless Communications Series. From 1996 to 1998, he was the Chair of the Technical Committee on Personal Communications of the IEEE Communications Society.

Dr. Chuang was elected a Fellow of the IEEE in 1997 "for contributions to
radio link techniques, system architecture, and resource management of low
power wireless personal communications." He is a member of Phi Kappa Phi.

All are welcome to attend.
