Deploying WPA2-Enterprise requires a RADIUS server, which handles the task of authenticating network users access. The actual authentication process is based on the 802.1X policy and comes in several different systems labelled EAP. Because each device is authenticated before it connects, a personal, encrypted tunnel is effectively created between the device and the network.
