This course is brought to you by the authors of the best-selling book Fundamentals of WiMAX (Prentice Hall, 2007), the definitive resource on WiMAX with over 10,000 copies sold and the first comprehensive guide to WiMAX - its technical foundations, features, and performance. The course will provide students with a broad understanding of WiMAX and will provide wireless engineers, network architects and system designers with the essential information for succeeding with WiMAX-from planning through deployment. The course also offers insights to other network technologies such as LTE, HSPA & EVDO.
Who Should Attend:
This course is designed for wireless engineers, network architects and system designers who will be working on WiMAX products and services. Students will especially appreciate their detailed discussion of the performance of WiMAX based on comprehensive link and system-level simulations.
Course Overview:
The first day of the course provides a treatment of the technical building blocks of wireless broadband networks. It starts by teaching the technical foundations of broadband wireless systems such as channel modeling and cellular design. The first day also provides a substantial introduction to OFDM and OFDMA, Multi-antenna techniques like Space Time Coding and MIMO, multiple access techniques and scheduling. A comparison between WiMAX, LTE, EVDO and HSPA networks is also presented. These concepts provide a solid foundation that is needed in order to understand the PHY and MAC Layers of WiMAX.
On the second day of the course we provide an overview the PHY and MAC Layers of WiMAX. We also provide a description of the network architecture of WiMAX and explain how essential service level functions such as QoS management, authentication, security, and mobility management are provided in WiMAX.
