Which of the following is a common standard for wireless local area networks (WLANs)?

• A. IEEE 802.3
• B. IEEE 802.11
• C. IEEE 802.15
• D. IEEE 802.16

Answer: (B)

IEEE 802.11 is the standard commonly associated with wireless local area networks (WLANs). This standard outlines the protocols and technologies used for implementing wireless networking, allowing devices to connect to a local network without the need for wired connections. It encompasses a range of specifications that cater to different frequencies and transmission rates, such as 802.11a, 802.11b, 802.11g, and more modern versions like 802.11n, 802.11ac, and 802.11ax. The significance of IEEE 802.11 lies in its broad adoption and versatility, providing foundational technology for Wi-Fi as we know it today. This standard has enabled a dramatic increase in mobile connectivity and has facilitated the proliferation of wireless devices in both personal and commercial environments, allowing for flexible networking solutions. In contrast, IEEE 802.3 pertains to wired Ethernet networks, focusing on LAN standards over physical cabling. IEEE 802.15 addresses wireless personal area networks (WPANs), which typically cover much shorter ranges compared to WLANs. IEEE 802.16 defines standards for broadband wireless access, mainly used in metropolitan area networks (MANs) rather than WLANs. Therefore, IEEE 802.11
