RF Fundamentals Course

The RF Fundamentals Course builds practical knowledge of how radio signals are generated, transported, propagated, measured, and received. Learners examine frequency, wavelength, spectrum, power, decibels, transmission losses, antennas, propagation, line-of-sight requirements, interference, and receiver performance. Technician-focused examples connect theory to coverage planning, installation, testing, and fault diagnosis. By completing the course, learners can interpret common RF specifications, perform basic calculations, recognize conditions that degrade wireless links, and make safer, better-informed field decisions across land-mobile radio, cellular, microwave, and satellite systems.
