Radio signals don’t just travel in straight lines - they interact with the environment in
complex ways. Understanding how propagation works, and what affects coverage and
interference, is essential for anyone involved in wireless communications, broadcasting, or
network planning.

In this single-module course, you’ll start with the fundamentals of radio propagation,
exploring how signals behave across different frequency bands - from VLF and LF through
HF, VHF, and beyond. You’ll learn about the role of the ionosphere, how conditions vary
between day and night, and how space waves enable long-distance communication.
Next, you’ll examine radio coverage, including key factors such as reflection, scattering,
diffraction, and attenuation. The course explains how terrain, clutter, and atmospheric
anomalies impact signal reach, and why coverage planning is critical for reliable service.

Finally, you’ll dive into radio interference, covering issues like co-channel and adjacent
channel interference, illegal operation, and frequency planning. You’ll also explore how
weather conditions and noise affect performance, and what strategies help mitigate these
challenges.

Designed for professionals in telecoms, broadcasting, and wireless technologies, this
course provides a clear, practical introduction to radio propagation, coverage, and
interference - ideal for anyone seeking to understand the principles behind reliable radio
communication.
