Features: With the continuous innovation of multimedia services, wireless access technology is trending towards high bandwidth and IPization. As a next-generation broadband wireless access technology, WiMAX/802.16 is gaining increasing attention due to its inherent advantages. The air interface defined by wireless access technology typically only involves the lower two layers of the OSI seven-layer protocol architecture. This book separately explains the working principles of the MAC layer and physical layer of WiMAX. WiMAX was the first wireless access standard to propose QoS guarantees at the MAC layer, so this book provides a detailed discussion of the QoS mechanisms in the MAC layer, including service flow partitioning and scheduling, various bandwidth request methods, conflict resolution mechanisms, and more. On the other hand, the support of the MAC layer for the physical layer is also an important aspect in ensuring that the WiMAX communication system can provide QoS guarantees. Compared to fixed WiMAX, mobile WiMAX (i.e., IEEE 802.16e) has a better market prospect but also faces more challenges. Chapter 9 of this book thoroughly explores the improvements made by mobile WiMAX and the smooth transition from fixed WiMAX to mobile WiMAX. Finally, this book covers the deployment and implementation of WiMAX networks, as well as other emerging communication technologies that coexist with WiMAX, such as HSDPA, IEEE 802.11n, and Wireless Mesh Network (WMN). This book can serve as a reference for engineers, researchers, technical personnel, and students majoring in communication-related fields who are involved in actual network deployment and operation, as well as for self-study purposes.
