Description
WiMAX (Worldwide Interoperability for Microwave Access- IEEE 802.16) is a standards-based wireless MAN 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, high-speed enterprise connectivity for businesses and mobile.
This 2-day course provides an overview of WiMax applications, technologies, architectural and standards. Other important topics such as protocol layers, QoS, throughput, security, coverage, capacity planning, interference, testing and interoperability, are discussed. Basic WiMAX architecture, RF theory, microwave, propogation, Link budget math, troubleshooting, security and QoS 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) foundations, protocols, PHY, MAC (Media Access Control), framing, TDD/FDD, FDMA/OFDMA/SOFDMA, QoS, security, mobility and CSN/ASN. Real-world experiences through case studies, vendor products, and implementation tips located throughout the course reference material.

This is an excellent course. The instructor knows the material very well and he communicates with class very well. The group sessions were very useful, this exercise gave us an opportunity to do a case study that gave a feel for all aspects that should be considered from the planning to implementation stage of a WIMAX network. I strongly suggest this class to every one.
