Use Cases and Deployment Scope
We use WLC for centralized management of APs. We do not have that many APs, but still having a central point for configuration and troubleshooting simplifies things. Also, users require reliable roaming between APs, so having WLC is crucial.
We use wifi as a main connectivity option in our office so it need to be reliable.
