What is a WLAN Controller (WLC)?

A WLAN Controller (WLC) manages and monitors wireless access points (APs) in a WLAN and allows wireless devices to connect to the WLAN. You typically install a WLC in a centralized location, to which your APs are connected, either directly or indirectly.

You can look at a WLC as something akin to a speaker's amplifier. It can amplify network bandwidth so that a wireless device can reach it even when it is far away. It also allows administrators to view bandwidth usage, hardware status and all the clients that are connected to the WLAN, which can help you troubleshoot problems with it.

WLCs are beneficial as well when it comes to scaling your WLAN. They allow you to easily deploy and manage new APs as you add them to the WLAN.

Today, there are also controller-less APs that allow you to manage them through a single interface without the need of a physical WLC.
