Which IEEE standard is Wi-Fi part of?

Wi-Fi is part of the IEEE 802.11 standard, which defines the protocols and technologies for wireless local area networks (WLANs). This standard outlines how wireless devices communicate within a network, specifying aspects such as frequency bands, modulation techniques, and error correction protocols. The 802.11 standard has undergone several revisions and enhancements over time, leading to various Wi-Fi specifications such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, and 802.11ax, each offering different performance characteristics and capabilities.

In contrast, other IEEE standards mentioned relate to different networking technologies. For example, IEEE 802.15 is associated with personal area networks (PAN), IEEE 802.16 focuses on broadband wireless access (such as WiMAX), and IEEE 802.3 pertains to Ethernet networks, which are primarily wired LAN technologies. Understanding that Wi-Fi operates under 802.11 is crucial for anyone involved in network defense and management, as it helps in addressing wireless security issues effectively.
