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.
