Which standard is associated with Wireless Local Area Networks?

1. IEEE 802.15

2. IEEE 802.11

3. IEEE 802.3

4. IEEE 802.16

The correct answer is: IEEE 802.11

The standard associated with Wireless Local Area Networks (WLANs) is IEEE 802.11. This standard outlines the protocols for implementing wireless networking for devices within a limited area, allowing for the connection of various devices such as laptops, smartphones, and tablets to a local network without physical cables. IEEE 802.11 is the foundational standard that enables Wi-Fi technology, which is widely used in homes, offices, and public spaces to provide wireless internet access. Within this standard, there are several amendments (like 802.11a, 802.11g, 802.11n, etc.) that specify different technologies and capabilities, such as data rates and frequency bands. The other standards mentioned are associated with different types of networks or technologies. For example, IEEE 802.15 pertains to personal area networks (PANs), like Bluetooth; IEEE 802.3 relates to Ethernet, which is a wired networking technology; and IEEE 802.16 encompasses broadband wireless access networks, often referred to as WiMAX. Each of these standards serves different purposes and types of connectivity, making IEEE 802.11 the correct choice for WLANs.
