How does wireless self-healing coverage function?

Wireless self-healing coverage is a feature designed to maintain wireless connectivity and performance, especially in environments where obstacles or interference can create coverage gaps. The correct choice explains that when a wireless access point (AP) encounters a failure or reduced performance, the Wireless LAN Controller (WLC) actively adjusts the situation to maintain coverage in the area.

When one AP goes down, the WLC can analyze the service area and boost the transmission power of surrounding APs in order to fill the gaps in coverage caused by the failed AP. This dynamic adjustment allows for continued connectivity for clients that would otherwise lose service due to the failure of a single AP. By increasing power from existing, functioning APs, the network can mitigate the impact of the failure without needing immediate physical replacement or addition of hardware.

The effectiveness of this self-healing capability lies in its ability to maintain the network's overall integrity while minimizing downtime, which can be crucial for environments that rely heavily on wireless communications. This process is advantageous as it is seamless to the user, maintaining a stable connection even when an issue occurs in the network infrastructure.
