Configuring Hotspots

Traditionally, using a hotspot presents end users with several challenges, including initial connection issues, security concerns, and connectivity while roaming. The ExtremeWireless solution 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 WPAv2.

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 site 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.
