Making the Wi-Fi Roaming Experience as Secure and Easy to Use as With Cellular Data
Hotspot 2.0 is focused on enabling users to automatically and securely connect to Wi-Fi networks while on the move. This is very much the cellular experience that we all enjoy when getting off an airplane just about anywhere in the world. By the time you've unlocked your smartphone it has already selected a roaming partner, exchanged credentials, and securely downloaded your email.
Wi-Fi roaming would apply anytime a mobile device does not see an access point belonging to its home network provider. A user could roam on a Wi-Fi network that is across the street, across town or on the other side of the world. Roaming partners can include MSOs, MNOs, wireline operators, public venues, enterprises, and basically any other entity that has Wi-Fi assets.
With Hotspot 2.0, the home operator loads a credential unto the mobile device and the options here include SIM cards, username/password, or X.509 digital certificates. The wireless device can then query a Hotspot 2.0 capable AP to see if it belongs to a visited network that supports roaming with the wireless device's home network. A mobile device can support credentials from more then one service provider.
