Where is the wireless LAN controller located in a mobility express deployment?

A dedicated server is typically used for traditional hardware-based WLCs, not for the integrated solution offered by Mobility Express deployments.

Cisco Mobility Express deployments embed the wireless LAN controller software directly onto a compatible access point, eliminating the need for a separate hardware controller appliance. This chosen access point then functions as the master controller, managing other access points in the deployment.

While cloud-managed Wi-Fi solutions exist, Cisco Mobility Express refers to an on-premises solution where the WLC functionality is embedded within an access point.

Mobility Express still requires WLC functionality; it's simply integrated into an access point rather than being a separate appliance or absent from the network.
