Description

WiMAX (Worldwide Interoperability for Microwave Access- IEEE 802.16) is a standards-based wireless technology (an implementation of 802.16: 802.16-2004 and 802.16e) that provides high-throughput broadband connections. WiMAX can be used for a number of applications, including "last mile" broadband connections, hotspot and cellular backhaul, and high-speed enterprise connectivity for businesses.

This course provides a detailed technical view of WiMax RF Planning and Network Design. It is an advanced course reviewing the technical specifications and standards from a RF Network Planning and Implementation point of view.

This course provides an overview of WiMax RF, technologies, applications and standards. Other important topics such as protocol layers, QoS, throughput, coverage, capacity planning, testing, interoperability, interference and security are discussed. Basic RF theory, microwave, LOS, NLOS, Link budget math, troubleshooting foundations and site survey are explored.

After a general introduction to wireless networks, this practical course moves quickly into the WiMax (802.16-2004, 802.16e) protocols, PHY, MAC (Media Access Control), framing,TDD/FDD, FDMA/OFDMA, RF planning and design. Real-world experiences through case studies and implementation tips located throughout the course reference material.
