Course Overview
Course in a Nutshell
This course offers a detailed technical treatment of the subject of WIMAX radio planning. It is an advanced course reviewing the technical specifications and standards from an RF network planning and implementation perspective.
The course provides an overview of the WIMAX/WiMAX Mobile technologies, standards, and applications. Important topics such as protocol layers, QoS, throughput, coverage, capacity planning, testing, interoperability, interference and security are thoroughly discussed. Basic RF theory, microwave, Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) links, link budget analysis, troubleshooting foundations, and site survey are also studied. The RF planning techniques taught in this course cover both the IEEE 802.16d and IEEE 802.16e standards. The course uses hands-on exercises, case studies, and demos to make the content easier to apply back on your job.
