AUDIENCE:   Technical staff responsible for WiMAX network planning, design, operation, testing, support or troubleshooting. Technical staff responsible for implementing and supporting WiMAX networks and other wireless networks, including design engineers, field engineers, test engineers, software and hardware developers. PREREQUISITES:   Before attending the course, delegates should have a basic understanding of wireless or radio communications, and IP networking. DURATION:   3 days. OBJECTIVES:   WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 standards-based wireless network technology that provides high-throughput broadband wireless network service. WiMAX is being deployed in a range of applications, including last mile broadband service, hotspot services, cellular network backhaul, and high-speed enterprise wireless connectivity. This comprehensive WiMAX training course provides an in-depth coverage of WiMAX technologies, applications, standards and protocol layers. Important topics such as quality of service, throughput, coverage, interoperability, interference and security are also discussed. This comprehensive WiMAX course also covers essential RF theory, microwave propagation, RF link budget calculations, WiMAX security and additional security techniques used with WiMAX networks and WiMAX site survey are also examined. The design, planning and implementation of these networks, including dealwith interference are also examined. The course ends with a look towards future evolution in Broadband Wireless Access. The course covers the details of the WiMAX IEEE 802.16, 802.16a, 802.16-2004, 802.16e, 802.16 physical layers, 802.16 Media Access Control (MAC), 802.16 framing, TDD, FDD, WiMAX security and WiMAX QoS. All delegates receive a comprehensive WiMAX course reference manual incorporates real-world examples and experiences, with case studies and implementation guidelines. On completing this course, delegates will: Understand the fundamental concepts behind all 802.16 / WiMAX networks. Understand the WiMAX air interface specification. Understand WiMAX RF planning concepts and issues. Understand WiMAX network coverage and capacity planning. Understand the different types of 802.16 WiMAX systems and commercial offerings. Be able to differentiate between and select from the range of emerging WiMAX implementations. Gain the foundation knowledge needed for the efficient design and support of WiMAX solutions.
