Which device serves as a centralized manager for wireless access points?

A Wireless Controller serves as a centralized manager for wireless access points. This device allows network administrators to manage multiple access points from a single interface, making it easier to configure settings, apply security policies, and monitor performance across the wireless network. In environments with numerous access points, a Wireless Controller simplifies management by centralizing the wireless network's configuration and operational controls, enhancing efficiency and consistency.

By utilizing a Wireless Controller, organizations can streamline the deployment of access points and ensure that they operate cohesively within the network. It enables features such as load balancing, roaming, and automated firmware updates, all of which bolster network performance and security.

In contrast, an Access Point serves as a gateway for wireless devices to connect to a wired network but does not provide centralized management capabilities. A Range Extender amplifies the signal of an existing wireless network to improve coverage but lacks the centralized management features of a Wireless Controller. A Switch may be responsible for connecting different devices within a network but does not manage wireless access points. Thus, the Wireless Controller is the device specifically designed for centralized management of wireless networks.
