It includes WRIX-i (Interconnect), WRIX-l (Location) WRIX-d (Data Clearing) and WRIX-f (Financial Settlement). Each of these can be deployed by Visited Network Providers (VNPs) and Home Service Providers (HSPs) either in-house or through an intermediary WRIX service provider. The WBA WRIX was the winner of Wireless Broadband Innovation 2007 award in the Best Wi-Fi Product / Service segment. The latest release of WRIX includes support for EAP authentication providing the transport and indicating which radius attributes to use. This specification recommends Network operators support the following EAP methods: EAP-SIM, EAP-AKA, EAP-TLS, and EAP-TTLS.
