This module demystifies the invisible world of wireless networking. You will explore the fundamental physics of Radio Frequency (RF), including concepts like frequency bands (2.4 GHz, 5 GHz, 6 GHz), channels, interference, and signal attenuation. You will also trace the evolution of IEEE 802.11 standards, from legacy 802.11b/g/n to modern high-efficiency protocols like Wi-Fi 6 (802.11ax) and Wi-Fi 7 (802.11be). From a cybersecurity perspective, understanding RF behavior and channel utilization is critical for detecting wireless jamming, identifying rogue access points, and designing resilient, interference-free wireless architectures.
