What requires a Radius server?

Explanation:
WPA-Enterprise is the mode that requires a Radius server. In enterprise Wireless (WPA-Enterprise), authentication is performed through 802.1X using an Extensible Authentication Protocol (EAP). The access point forwards the user’s credentials to a Radius server, which validates them against a directory service (like Active Directory) and provides authorization and accounting. This setup supports unique per-user credentials and scalable management for many users and devices. Other modes use a pre-shared key or no authentication at all, so they don’t rely on a Radius server. WPA-PSK uses a single shared key for all clients, Open WPA offers no authentication/encryption, and WEP uses a static key stored on devices. That’s why WPA-Enterprise is the configuration that requires a Radius server.
