Redes Inalámbricas (WLAN)

A final chapter, Chapter 8, concludes the book with a vision for future. Definition for Fourth Generation (4G) mobile communications, Beyond Third Generation (B3G), and future generations are given. The need for these technologies from user, vendor, and operator perspectives is also discussed in this chapter. Technological enhancements needed from the protocol layer point of view and particularly for security, QoS, and mobility are also presented in the chapter. In this book several draft standards are discussed which might change with time; still the information in this book should be beneficial for understanding the interaction between the IP and MAC layers. We hope that this book will be of interest to business and technical managers and also to technical novices as well as experts in this field.

This book is intended as a concise but thorough ready reference for requirements analysts (RAs)—those who are assigned to determine the requirements for planned systems and software, both in computing and engineering. It is a desk guide/handbook that focuses on how RAs can best perform their work. The requirements are key to the success or failure of technical projects. They are the basis of all of the follow-on work. It’s been my experience that most projects and organizations fail to use effective requirements practices and a documented requirements process, and also that those assigned as RAs are cast into the needed work without proper preparation, experience and training, and without a good handbook that advises them on how to perform their roles and what to do.
