T1. Mobile Commerce: Issues, Applications and Technologies

Upkar Varshney, Georgia State University, USA

Interest in mobile commerce is growing tremendously in the research and development community. Some projections of this market estimate its value at several hundred billions of dollars. With significant wireless penetration in many European countries and Japan, the mobile commerce market is already taking off and reaching billions of dollars annually. Mobile commerce may require significantly different approaches in design, development, and implementation of applications due to the inherent characteristics of wireless networks and mobile devices. Many important challenges include design and development of m-commerce applications, networking requirements, transactions and security issues, business models and strategies. This tutorial will include discussion of a variety of issues in mobile commerce, from both technical and business application points of view.

Upkar Varshney is on the faculty of Computer Information Systems at Georgia State University in Atlanta. He is credited with some of the early research on mobile commerce. He has written over 50 papers on mobile commerce, wireless networks, and high speed networking in major journals and for international conferences. He was the guest editor for ACM/Kluwer Journal on Mobile Networks and Applications (MONET) special issue on Mobile Commerce (June 2002).

T7: Smart Antennas, Turbo Coding, Space-Time Coding, Adaptive Transceivers, Intelligent Networking and 'all that' for Improved QoS

Lajos Hanzo, University of Southampton, United Kingdom

This tutorial will provide an overview based on the Wiley/IEEE Press monographs "Blogh, Hanzo: Third-Generation Systems and Intelligent Wireless Networking: Smart Antennas and Adaptive Modulation"; "L. Hanzo, et al.: Adaptive Wireless Transceivers"; "L. Hanzo, et al.: Turbo Coding, Turbo Equalisation and Space-Time Coding". This short course provides an insight into the effects of turbo-coded, turbo-equalized and space-time coded adaptive TDMA, CDMA and OFDM transceivers, as well as smart antennas and a range of other efficient networking techniques on the achievable teletraffic capacity of wireless systems. This research-oriented presentation considers the joint benefits of both physical and network-layer performance enhancement techniques.

More specifically, conventional systems would drop a call in progress if the communications quality falls below the target quality of service and cannot be improved by handing over to another physical channel. By contrast, the adaptive transceivers of the near future are expected to simply "instantaneously drop the throughput, rather than dropping the call" by reconfiguring themselves in a more robust mode of operation. It is demonstrated that the proposed beam-forming and adaptive transmission techniques may double the expected teletraffic capacity of the system, while maintaining the same average performance as their conventional fixed-mode counterparts.

Lajos Hanzo has held various academic and research positions in Hungary, Germany and the United Kingdom during his 26-year career. Since 1986 he has been with the University of Southampton, United Kingdom where he holds the Chair of Telecommunications. Hanzo has published about 400 research papers and eight John Wiley/IEEE Press books. He is also an IEEE Distinguished Lecturer.

T9: Mobile VPN and Other Advanced Data Services

Alex Shneyderman, BlueCube Technologies, USA

Subjects covered in this tutorial will include 3G data networking and Wireless Virtual Private Networking. The convergence of wireless and data technologies and the exponential growth of the Internet have made IP VPNs an important vehicle for communicating business information via public infrastructures. But as wireless technology becomes increasingly sophisticated and standards activity heats up, Mobile VPNs (MVPNs) are fast moving from concept to reality. That's not surprising. MVPNs have the potential to enable unprecedented wireless services (i.e. mobile commerce, push applications, remote collaborative computing) with all the quality of the wired network. And, as these advances transform mobile devices into productivity tools for companies, carriers have the opportunity to premium pay revenues. To realize this potential service providers should be able to design and implement infrastructures based on the next generation wireless standards that enable MVPN services (i.e. General Packet Radio Service (GPRS), Universal Mobile Telecommunication System (UMTS) and CDMA2000, among others).

Alex Shneyderman received a B.S. from Polytechnic University of New York in 1995. From 1995 to 1997 he worked at Verizon Communications (NYNEX) in telecommunications engineering.

T4. CDMA2000 1xEV-DV

Young C. Yoon, Shiau-He Tsai and Aleksandar D. Damnjanovic, Ericsson Wireless Communications, USA

The CDMA2000 family of standards is based upon code division multiple access (CDMA) technology and is one of the defined modes in the International Telecommunication Union (ITU) 3G wireless standard. The early releases of the CDMA2000 standard support high-speed data transmission (up to 307.2 kbps) using dedicated data channels. The latest release, Release C, significantly increases the efficiency of the air interface by introducing a high-speed shared packet data channel (with a peak data rate of 3.091 Mbps) while maintaining backward compatibility with previous releases. This release, commonly referred to as 1xEV-DV (for 1xRTT Evolution for high-speed integrated Data and Voice), was approved in May 2002 by the Telecommunication Industry Association (TIA) and submitted to ITU for inclusion in the next revision of its 3G standard.

This tutorial will cover a number of key features of 1xEV-DV, including the design of the high-speed shared data channel, its components (Hybrid-ARQ, link adaptation, modulation and coding, scheduling, cell-switching, channel supervision, control/hold etc.), MAC, and the effect of mixing data and voice services. It will also discuss in detail how 1xEV-DV exploits the channel and data structure to significantly increase the spectral efficiency.
