What is a key benefit of Intra-controller roaming?

Intra-controller roaming refers to the process whereby a wireless client moves between access points that are managed by the same wireless LAN controller (WLC) without losing its connection. A key benefit of this mechanism is that it provides seamless connectivity for clients while they transition from one access point to another within the same controller's domain.

When a client roams from one access point to another that is under the same WLC, the process is relatively quick and efficient. This quick transition is facilitated by the fact that the authentication and session information of the client is retained on the controller, allowing for minimal disruption. As a result, applications that rely on continuous data streams, such as voice over IP (VoIP) or video conferencing, experience fewer interruptions and maintain quality of service. This feature is critical in environments like offices or universities, where users frequently switch between coverage areas.

The other options, while potentially beneficial in different contexts, do not directly pertain to the main advantage of intra-controller roaming. Therefore, the answer focusing on seamless connectivity accurately captures the essence of what intra-controller roaming achieves for wireless clients.
