Wi-Fi @ Open Roaming

Wi-Fi OpenRoaming is a standards-based initiative developed by the Wireless Broadband
Alliance (WBA) to simplify and secure Wi-Fi access for users across different networks and
venues. It aims to provide seamless connectivity experiences similar to cellular roaming,
where users can automatically connect to Wi-Fi networks without the need for manual
authentication or configuration.

Here are the key aspects of Wi-Fi OpenRoaming:

• Seamless Connectivity: Wi-Fi OpenRoaming allows users to seamlessly connect to
participating Wi-Fi networks without the need to manually select or authenticate to
each network. Once a user's device is configured for OpenRoaming, it can
automatically connect to any Wi-Fi network that supports the standard.
• Hotspot 2.0: Wi-Fi OpenRoaming is built on the Hotspot 2.0 (HS2.0) framework,
which provides secure and automatic network discovery, selection, and connection.
HS2.0 enables devices to securely authenticate and connect to Wi-Fi networks using
digital certificates, eliminating the need for manual login screens or captive portals.
• Identity Federation: OpenRoaming relies on identity federation to securely
authenticate users across different networks and service providers. Users' identities
are managed by Identity Providers (IdPs), which issue digital certificates or credentials
that can be used to authenticate users on participating Wi-Fi networks.
• Participating Ecosystem: Wi-Fi OpenRoaming is supported by a growing ecosystem
of network operators, service providers, device manufacturers, and technology
vendors. These organizations collaborate to implement OpenRoaming standards and
enable seamless connectivity experiences for users across different venues and
• Security and Privacy: OpenRoaming incorporates robust security and privacy
mechanisms to protect users' data and credentials. It utilizes industry-standard
encryption protocols and authentication methods, such as Transport Layer Security
(TLS) and Extensible Authentication Protocol (EAP), to ensure secure communication
between devices and networks.
• Global Reach: Wi-Fi OpenRoaming aims to create a global federation of Wi-Fi
networks, allowing users to roam seamlessly between networks in different countries
and regions. This provides travelers and mobile users with consistent connectivity
experiences worldwide, without the need for manual network configuration.
• Use Cases: Wi-Fi OpenRoaming can benefit a wide range of use cases, including
public Wi-Fi hotspots, enterprise networks, hospitality venues, transportation hubs,
and smart cities. It enables users to stay connected and productive while on the go,
whether they are commuting, traveling, or working remotely.
Overall, Wi-Fi OpenRoaming promises to revolutionize Wi-Fi connectivity by providing
seamless, secure, and ubiquitous access to Wi-Fi networks for users worldwide. It simplifies
the process of connecting to Wi-Fi and enhances the user experience by eliminating barriers
to access and improving network interoperability.
