Hotspot

ExtremeCloud IQ Controller supports the definition of Hotspot 2.0 service for AP39xx and Wi-Fi 6 access points deployed in a Centralized site, and simplified configuration for WBA OpenRoaming on Hotspot 2.0 networks.

When configuring a hotspot, you have the option to use WBA OpenRoaming for a simplified NAI routing configuration that automatically creates a AAA policy. Or you can configure a traditional hotspot and enable NAI routing in the AAA Policy that you configure. WBA OpenRoaming is a simplified configuration for a hotspot that uses a single realm. But if you need a hotspot configuration that can support multiple realms on the same radio, configure a traditional hotspot and a AAA policy that enables NAI routing and multiple realms.

Traditionally, using a hotspot presents end users with several challenges, including initial connection issues, security concerns, and connectivity while roaming. Hotspot 2.0 offers the following features to improve the hotspot end-user experience:

Pre-association network discovery and selection using the dot11u ANQP protocol, resulting in a seamless initial connection.
Simplified account registration. Network administrators create accounts easily, and provisioning is achieved without user input.
Enhanced security, using over the air transmission secured by WPA2 or WPA3.
Simplified WBA OpenRoaming.
NAI Routing. When NAI Routing is enabled, RADIUS Servers can be associated with realms.

Each hotspot WLAN has its own Access Network Query Protocol (ANQP) configuration. The HESSID and ANQP Domain ID are specific to the hotspot WLAN.

With pre-association, a mobile device uses ANQP to perform network discovery. The mobile device's connection manager uses hotspot information, such as the service provider policy and user preferences, to automatically select a hotspot network. A mobile device queries the hotspot for key service provider identification and authentication information and selects a network. The ANQP response is generated using parameters configured by the hotspot operator.

Only one hotspot WLAN can be assigned to an AP and to a specific Profile configuration. The hotspot WLAN can refer to a single Online Signup (OSU) WLAN, which can be open or encrypted. Network operators define the filter policy during hotspot configuration.
