Under WBA guidance, the OpenRoaming federation enables end users to connect to networks managed by Access Network Providers (ANP) such as airports, shopping malls, operators, hospitality centers, sports venues, corporate offices, and municipalities, while using credentials managed by Identity Providers (IDP) such as operators, internet providers, social media providers, device manufacturers, and cloud providers.
OpenRoaming is based on the industry standards Wi-Fi Alliance Passpoint (Hotspot 2.0) and RadSec protocol, which ensure end-to-end security. Passpoint protocol ensures enterprise-grade wireless security supporting various EAP authentication methods.
Using the Passpoint Roaming Consortium Organization Identifiers (RCOIs), OpenRoaming supports both settlement-free use cases where free Wi-Fi is offered to end users, as well as settled, or paid, use cases. The settlement-free RCOI is 5A-03-BA-00-00, and the settled is BA-A2-D0-xx-xx, for example BA-A2-D0-00-00. Different bits in the RCOI octets set various policies, such as Quality of Service (QoS), Level of Assurance (LoA), Privacy, and ID-type.
