TIP OpenWiFi devices implement support for both the air interface and systems interfaces necessary to support Passpoint® Release 2 and above. Once also termed Hotspot 2.0, IEEE 802.11u specified added air interface fields exposing Access Network Query Protocol interactions for clients to discovery Access Point capabilities.
Wi-Fi Alliance expanded ANQP to include Online Signup (OSU) concepts to leverage seamless onboarding and client security for Passpoint® networks. Following on from these efforts, Wireless Broadband Alliance has provided the necessary system interfaces for identity, security, mobile offload within a common federated operator solution known as OpenRoaming.
TIP OpenWiFi enables operators to deploy the full range of Passpoint® and OpenRoaming solutions.
