Course 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, and high-speed
enterprise connectivity for businesses.
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 RF theory, microwave, propagation, 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, QoS security and mobility. Real-world
experiences through case studies, vendor products, and
implementation tips located throughout the course reference
material.
