Course Overview

This course aims to equip professionals with the advanced knowledge and skills required to plan, design, and optimize satellite networks. It is designed for professionals who possess a working knowledge of satellite communications (SATCOM) and who desire to deepen their knowledge in network planning and satellite use cases.

Participants will first be brought through a recap of SATCOM basics, and thereafter delve into advanced topics like link power budget, propagation delays, free space loss, satellite use cases for 5G, and more. Participants will also learn how to ensure security in satellite systems and how to leverage satellite services to increase network efficiency through more efficient use of bandwidth.

During the course, live demonstrations on satellite radio link planning will be conducted for participants to get hands-on experience on the tools and techniques used in SATCOM.
