RF Spectrum Analysis for Wireless Communications introduces the fundamental principles of radio frequency (RF) signals and their analysis using a spectrum analyzer.

The course provides participants with a practical understanding of how wireless communication systems use the radio spectrum.

Participants will learn the basic concepts of wireless communications, the electromagnetic spectrum, and the generation and transmission of

electromagnetic waves.

The training explains how different wireless technologies produce unique spectral signatures that can be observed and interpreted using spectrum analysis tools.

Through guided demonstrations and hands-on exercises using a spectrum analyzer simulator, participants will learn how to identify and analyze signals from common wireless technologies, including GSM, UMTS, LTE, 5G NR, WiFi, and Bluetooth.

The course also introduces fundamental RF signal types, such as continuous-wave (CW), pulse, noise, and RF interference, including jammers.

By the end of the course, participants will be able to configure basic spectrum analyzer settings, interpret RF spectrum displays, and recognize the spectral characteristics of modern wireless communication systems.

The practical lab component allows participants to apply theoretical concepts by analyzing simulated RF signals and identifying different wireless technologies in the spectrum.

This course is designed for ECE students, RF engineers, telecom technicians, and wireless professionals who want to develop a foundational understanding of spectrum analysis and wireless signal identification.
