Cisco Unified Wireless Network solution WLANs support four levels of QoS: Platinum/Voice, Gold/Video, Silver/Best Effort (default), and Bronze/Background.

When configuring Quality of Service (QoS) for a voice over wireless LAN (VoWLAN) deployment in the Cisco Wireless LAN Controller (WLC) GUI, the QoS profile selected is typically the Platinum QoS profile.

The Platinum QoS profile is the highest-priority QoS profile available in the Cisco WLC. It is designed for real-time, delay-sensitive traffic such as voice and video. When this QoS profile is assigned to a WLAN, it ensures that voice traffic is given the highest priority and is transmitted with minimal delay, jitter, and packet loss.

The Bronze, Gold, and Silver QoS profiles are lower-priority QoS profiles that are typically used for non-real-time data traffic. These QoS profiles provide varying levels of quality of service based on the needs of the application or user. For example, the Bronze profile may be used for basic web browsing, while the Gold profile may be used for video streaming.

In summary, the Platinum QoS profile is selected in the Cisco WLC GUI when configuring QoS for a VoWLAN deployment, as it provides the highest priority and optimal performance for delay-sensitive voice traffic.
