What is the primary role of the controller in a controller-based wireless architecture?

The primary role of the controller in a controller-based wireless architecture is to centralize management and control of access points. This centralization allows for more efficient management of network resources, as the controller acts as the brain of the wireless network, overseeing the operation of all access points within its domain.

By centralizing the management, the controller simplifies tasks such as configuration, monitoring, and troubleshooting. It can enforce policies, manage firmware upgrades, and collect performance metrics from multiple access points, allowing for a comprehensive view of the network and enabling quick resolutions to any issues that may arise.

While improving client connectivity, managing user authentication, and providing internet access are important functions in a wireless network, they are often either benefits or consequences of having a centralized controller. In essence, the controller’s primary responsibility is to streamline and coordinate the management of access points, ensuring that the wireless network operates smoothly and efficiently.
