Wireless Local Networks -- a Revolution in Local Access

Wireless Local Networks -- a Revolution in Local Access introduces and thoroughly develops the key technical concepts and initiatives that are driving the global revolution in mobile computing services. Vital elements of this subject include understanding the challenges of effectively transporting data over the wireless medium, and adapting Internet service to this medium. This course covers the core enabling technologies that make delivery of data services over mobile systems practical and secure, and explores the exciting developments that are coming to define the emerging wireless telecommunications infrastructure.

The convergence of wireless communications and Internet technology is creating remarkable opportunities for innovation. 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 covers the essential elements of this emerging discipline, and develops an 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. Many of the details of just how the mainstream of Internet technology will be adapted to the mobile environment are still in process of getting sorted out. Regardless of these outcomes, it is certain that initiatives with Wireless LANs, Third Generation Mobile/Cellular, and Mobile IP are important developments in this area.

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 Material and Program Features
Each delegate is provided with a permanent, comprehensive workbook which is much more than a set of lecture notes. In addition to being a workbook designed to track with the lecture portion of the program, it is designed with features that give it real value as a permanent reference book.

These include:

• All text is presented in the form of complete fully descriptive sentences, designed to be a highly readable, long-term valuable reference on the job.
• A text-book style Subject Index and a comprehensive Table of Contents, consistent with effective reference access to content details.
• A thorough, highly readable subject-specific glossary which provides detailed descriptive treatment of key items of terminology.
