WiMAX stands for Worldwide Interoperability for Microwave Access. It is a set of wireless broadband communication standards which are based on IEEE 802.16. It provides media access control and multiple physical layer options. WiMAX 2+ is the latest version and it is a backwards-compatible transition from previous generations. Subscriber stations are the devices that provide connectivity to WiMAX network. It is a long-range system as it covers many kilometers. It uses a QoS mechanism that is based on connections between user device and the base station. WiMAX provides portable mobile broadband connectivity through various devices. It acts a wireless alternative to digital subscriber line and cable. It makes triple-play service offerings possible. Network of WiMAX can be accessed through USB when connected to dongle. WiMAX is an upcoming field of science that has undergone rapid development over the past few decades. This book is compiled in such a manner, that it will provide an in-depth knowledge about the theory and practice of WiMAX. Those in search of information to further their knowledge will be greatly assisted by this textbook.

Written and edited by experts who have developed WiMAX technology and standards WiMAX, the Worldwide Interoperability for Microwave Access, represents a paradigm shift in telecommunications technology. It offers the promise of cheaper, smaller, and simpler technology compared to existing broadband options such as DSL, cable, fiber, and 3G wireless. WiMAX Technology and Network Evolution is the first publication to present an accurate, complete, and objective description of mobile WiMAX technology. Each chapter was written and edited by experts, all of whom have been directly engaged in and lead the development of WiMAX either through the IEEE 802.16 Working Group or the WiMAX Forum. As a result, the book addresses not only key technical concepts and design principles, but also a wide range of practical issues concerning this new wireless technology, including: Detailed description of WiMAX technology features and capabilities from both radio and network perspectives WiMAX technology evolution in the near and long term Emerging broadband services enabled by the WiMAX networks Regulatory issues affecting WiMAX deployment and global adoption WiMAX accounting, roaming, and network management Each chapter ends with a summary and a list of references to facilitate further research. Wireless engineers, service designers, product managers, telecommunications professionals, network operators, and academics will all gain new insights into the key issues surrounding the development and implementation of mobile WiMAX. Moreover, the book will help them make informed management and business decisions in devising their own WiMAX strategies.

WiMAX Broadband Wireless Access Technology, based on the IEEE 802.16 standard, is at the origin of great promises for many different markets covering fixed wireless Internet Access, Backhauling and Mobile cellular networks. WiMAX technology is designed for the transmission of multimedia services (voice, Internet, email, games and others) at high data rates (of the order of Mb/s per user). It is a very powerful but sometimes complicated technique. The WiMAX System is described in thousands of pages of IEEE 802.16 standard and amendments documents and WiMAX Forum documents. WiMAX: Technology for Broadband Wireless Access provides a global picture of WiMAX and a large number of details that makes access to WiMAX documents much easier. All the aspects of WIMAX are covered. Illustrations and clear explanations for all the main procedures of WiMAX are pedagogically presented in a succession of relatively short chapters Topics covered include WiMAX genesis and framework, WiMAX topologies, protocol layers, MAC layer, MAC frames, WiMAX multiple access, the physical layer, QoS Management, Radio Resource Management, Bandwidth allocation, Network Architecture, Mobility and Security Features a glossary of abbreviations and their definitions, and a wealth of explanatory tables and figures Highlights the most recent changes, including the 802.16e amendment of the standard, needed for Mobile WiMAX Includes technical comparisons of WiMAX vs. 802.11 (WiFi) and cellular 3G technologies This technical introduction to WiMAX, explaining the rather complex standards (IEEE 802.16-2004 and 802.16e) is a must read for engineers, decision-makers and students interested in WiMAX, as well as other researchers and scientists from this evolving field.

The Definitive Guide to WiMAX Technology WiMAX is the most promising new technology for broadband wireless access to IP services. It can serve an extraordinary range of applications and environments: data, voice, and multimedia; fixed and mobile; licensed and unlicensed. However, until now, wireless professionals have had little reliable information to guide them. Fundamentals of WiMAX is the first comprehensive guide to WiMAX—its technical foundations, features, and performance. Three leading wireless experts systematically cut through the hype surrounding WiMAX and illuminate the realities. They combine complete information for wireless professionals and basic, accessible knowledge for non-experts.
