# Configuration Introduction

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.
