While in the past WiFi was considered not as secure as the cellular counterpart, things have been changing slowly and steadily. While the cellular is able to offer authentication using the EPS-AKA, Wi-Fi is now able to offer EAP-AKA and EAP-SIM.
In fact the above table is quite interesting to know about. Recently I was following a discussion that talked about the lack of QoS support in WiFi. As we can see, its supported but not guaranteed.
Devices that contain the USIM card can use EAP-AKA while that without one can offer EAP-SIM. EAP-AKA works in a similar way to the cellular authentication protocol EPS-AKA. For anyone who is interested in reading more details about the authentication and how it works, including signalling, see this whitepaper here.
