What is the primary use of a Wireless LAN (WLAN)?

The primary use of a Wireless LAN (WLAN) is to implement flexible data communication. WLANs enable devices to connect to a network wirelessly, offering mobility and convenience for users. This flexibility allows devices such as laptops, smartphones, and tablets to access the network from various locations within the coverage area without being physically connected through cables.

WLANs facilitate communication among devices in a localized area, providing similar network services as wired connections, while also allowing users the freedom to move around. This capability is particularly valuable in environments where mobility is essential—such as offices, schools, and public spaces—enabling seamless access to applications and data.

While WLANs can enhance network flexibility, they are not necessarily intended to completely replace wired LANs. Instead, they typically complement wired networks, offering additional options based on specific needs. Detecting rogue devices is a security feature associated with WLANs, but it is not their primary use; it serves more as a security measure within the broader context of WLAN deployment. Similarly, while connecting access points (APs) to the internet is part of WLAN architecture, the aim goes beyond just this function, focusing on overall flexible data communication between devices.
