High-Density WLAN Coverage
This section describes the recommended high-density network parameter settings. For details about how to configure APs and STAs to go online in high-density coverage scenarios, see Campus Network Connectivity Deployment. For details about user access authentication modes, see Wired and Wireless User Access Authentication Deployment.

Network Optimization in High-Density Scenarios
Network parameters in high-density scenarios are mainly set in the following profiles: VAP, SSID, traffic, RRM, 2G radio, and 5G radio profiles. After profiles are configured, configure their reference relationships to deliver high-density network parameter settings to APs in high-density scenarios. This example shows how to configure the reference relationships between profiles. The profile names are subject to the network plan.
