Wireless networking continues to evolve rapidly, and understanding the 802.11 family of standards is essential for modern network support. In this episode, we walk through the progression from 802.11a and 802.11b all the way to today’s high-speed 802.11ax (Wi-Fi 6). You'll learn which frequency bands each standard uses, what modulation types they employ, and the maximum data rates supported in typical environments.

We also explain backward compatibility between standards, channel widths, and the importance of features like MIMO and beamforming. This episode prepares you to compare and choose the right standard for specific applications, understand performance limitations, and configure devices for compatibility. Wireless is a major topic on the exam and in every real-world network—this episode ensures you're up to speed.
