Wireless and Satellite Communications

Introduction to Satellite Communication Technologies

Satellite communication technologies play a vital role in global connectivity by providing wide-area coverage, especially in remote and underserved regions. This track introduces the fundamental concepts of satellite communications, including orbital mechanics, satellite subsystems, payload design, and ground segment architecture. Participants will explore how satellites operate as relay stations in space, enabling long-distance communication for broadcasting, navigation, disaster management, and global internet services. The track highlights the unique characteristics of satellite channels, such as long propagation delays, Doppler effects, and atmospheric impairments.

In addition, this track examines the evolution of satellite communication systems from traditional GEO satellites to modern LEO and MEO constellations. It covers multiple access techniques, frequency bands, and modulation schemes used in satellite links. Practical challenges such as spectrum coordination, latency reduction, and cost efficiency are also discussed. By providing a comprehensive overview, this track equips participants with the foundational knowledge required to understand satellite-based communication networks and their growing role in future integrated communication infrastructures.
