T3: Broadband wireless access and high-speed wireless

data applications

Friday August 26, 2005, morning

Tutorial abstract

This tutorial will cover in detail 3G high-speed wireless technologies optimized for data applications. Extensions of these networks to support multicast will also be discussed. WiFi and WiMAX variations will be discussed and contrasted with 3G wireless technologies. Some of the 4G wireless technologies will be covered, subject to availability of time.

More specifically, the tutorial will focus on three main topics: (1) Transport, (2) Service Enablement and (3) Applications and Handsets. Transport section will encompass Media Access Control (MAC), Data-Link, Network, and Signaling details with extensions to Multicast for different types of networks including CDMA2000, UMTS, WiFi, WiMAX, and 4G technologies. Service Enablement will cover industry standard IP Multimedia Subsystem (IMS) architecture, components and protocols, and describe where the wireless industry is going with it. Applications and Handsets section will describe how handsets manufacturers and applications developers are collaborating to bring novel wireless broadband services to the market. Specific applications that will be discussed are Push to Talk, Push to View, and Broadcast-Multicast.

The tutorial will not only describe the technology, but will also provide the business context and the practical implications wherever it makes sense. Potential research ideas will also be covered so that those interested in being at the frontier of wireless broadband technology will also find the tutorial useful.

Intended audience

Researchers and engineers who want to understand the complete range of broadband wireless technology spanning local area, metro area and wide area networks. Attendees will learn the fundamental differences between different wireless access technologies, and be able to appreciate why some of the technologies do and do not work in certain environments and how best to make them interoperate. Familiarity with basic protocols and IP networks is assumed, but not required.
