Mobile Computing and The Wireless Internet: Developments in Cellular and Wireless LAN Systems

Mobile Computing and The Wireless Internet provides an introduction to the technical concepts and developments that are driving the global revolution in mobile services. Vital elements of this subject include the challenge of effectively transporting data over the wireless medium, and adapting Internet service to this medium. This course introduces the core enabling technologies that make delivery of data services over mobile systems practical, and explores the exciting developments that are defining the emerging wireless telecommunications infrastructure.

The convergence of wireless communications and Internet technology is creating remarkable opportunities for innovation in applications development. The remarkable changes that are happening in each of these two fields is noteworthy, but in combination, the momentum that these topics are generating in the industry is truly exciting. This short course introduces the essential elements that define this emerging discipline, and lays the groundwork of understanding of how these component parts contribute to vital new systems solutions.

The unprecedented growth and pace of innovation in the Internet and its related family of protocols and applications is now having a major impact on the mix of technologies that are part of the emergent mobile computing developments. Just how the mainstream of Internet technology will be adapted to the mobile environment is still not completely settled, although initiatives with Wireless LANs, Third Generation Mobile/Cellular, and Mobile IP are important developments in this area.

The course is intended to provide a balanced view of both local and wide area wireless data networking developments. Just as with wired networks, this scope covers both the privately owned and managed local networks and the shared wide-area infrastructure supported by public network providers.

The objectives of this course are:

• To provide an effective, up-to-date training experience that integrates the essential elements of this broad and quickly developing field.

• To offer participants an opportunity to appreciate the principles and embedded technologies that contribute to delivering data services in a wireless, mobile environment.

• To interpret and present a rationalized view of emerging initiatives in wireless networking.

Who Should Attend
This short course is designed to appeal to, and offer effective, highly usable knowledge to professionals that are affected by mobile/wireless data technology. This includes IT specialists, engineers, managers, planners and developers.

This course is intended to appeal to a range of backgrounds, ranging from junior/intermediate people needing a more comprehensive knowledge base, to specialists in one or more of the embedded disciplines who wish to broaden their professional skills.

Course Content Overview
The first sections of this short course provide a review the various technologies that contribute to the current trends in mobile data usage, with particular emphasis on cellular/mobile and Wireless LAN technologies.

Wireless LAN technology, in particular is a dynamic, growing class of service that is finding its way into many applications. This short course introduces a number of issues, technologies and solutions that bear on this exciting topic.
