Welcome to the Wireless Fundamentals course — your complete starting point for understanding how Wi-Fi really works. In this course, you’ll explore the invisible world of radio waves and learn how they carry data through the air. With clear explanations, real-world examples, and step-by-step labs, you’ll gain both the knowledge and confidence to work with modern wireless networks.
About
The Wireless Fundamentals course introduces you to the core ideas behind Wi-Fi and radio frequency (RF) communication. You’ll start with the basics — what radio signals are, how power and amplitude affect transmission, and how antennas shape signal patterns. Then you’ll dive deeper into Wi-Fi infrastructure, controller-based networks, and the 802.11 wireless standards.
Each section connects theory with practice. You’ll learn how to read wireless frames, understand signal strength and interference, and design better wireless networks. Whether you’re setting up home Wi-Fi or preparing for your CCNA, this course gives you the solid foundation you need.
What you'll learn
- Understand RF basics: Learn how radio signals behave, how power is measured in dB, and how interference affects performance.
- Explore Wi-Fi infrastructure: Understand how access points, controllers, and clients work together in modern WLANs.
- Master 802.11 standards: Study wireless frame types, addressing, and how devices avoid collisions using CSMA/CA.
- Secure your wireless network: Learn about authentication, encryption, and how to protect your WLAN from threats.
Skills you'll gain
