The table Interfaces is the highest administrative level for IEEE 802.11u and Hotspot 2.0. Here you have the option of enabling or disabling functions for each interface, assigning them different profiles, or modifying general settings.
- Interface
- Name of the logical WLAN interface that you are currently editing.
- IEEE 802.11u enabled
- Enable or disable support for connections according to IEEE 802.11u at the appropriate interface. If you enable support, the device sends the interworking element in beacons/probes for the interface or for the associated SSID, respectively. This element is used as an identifying feature for IEEE 802.11u-enabled connections: It includes, for example, the Internet bit, the ASRA bit, the HESSID, and the location group code and the location type code. These individual elements use 802.11u-enabled devices as the first filtering criteria for network detection.
- Hotspot 2.0
- Enable or disable the support for Hotspot 2.0 according to the Wi‑Fi Alliance® at the appropriate interface. Hotspot 2.0 extends the IEEE standard 802.11u with additional network information, which stations can request using an ANQP request. These include, for example, the operator-friendly name, the connection capabilities, operating class and WAN metrics. Using this additional information, stations are in a position to make an even more selective choice of Wi-Fi network.
- Internet
- Select whether the Internet bit is set. The Internet-bit explicitly informs all stations that the Wi-Fi network allows Internet access. Enable this setting if services other than internal services are accessible via your device.
Important: Using this function you only communicate the availability of an Internet connection. You configure the corresponding regulations on the firewall, irrespective of this option.
- ASRA – Additional steps for access required
- Select whether the ASRA bit (Additional Step Required for Access) is set. Using the ASRA bit explicitly informs all stations that further authentication steps are needed to access the Wi-Fi network. Enable this setting if you have, for example, set up online registration, additional authentication, or a consent form for your terms of use on your web site.
Important: Please remember to specify a forwarding address in the Network authentication types table for the additional authentication and/or WISPr for the Public Spot module if you set the ASRA bit.
- Network type
- Select a network type from the available list which most closely describes the Wi-Fi network behind the selected interface. Based on the setting made here, the user has the option to limit network detection of their devices to specific network types. Possible values are:
- Private network
- Describes networks which are blocked to unauthorized users. Select this type, for example, for home networks or corporate networks where access is limited to employees.
- Private with guest access
- Similar to Private network, but with guest access for unauthorized users. Select this type, for example, for corporate networks where visitors may use the Wi-Fi network in addition to employees.
- Chargeable public network
- Describes public networks that are accessible to everyone and can be used for a fee. Information about fees may be available through other channels (e.g.: IEEE 802.21, HTTP/HTTPS or DNS forwarding). Select this type, for example, for hotspots in shops or hotels that offer fee-based Internet access.
- Free public network
- Describes public networks that are accessible to everyone and for which no fee is payable. Select this type, for example, for hotspots in public, local and long-distance transport, or for community networks where Wi-Fi access is an included service.
- Personal device network
- In general, it describes networks that connect wireless devices. Select this type, for example, for digital cameras that are connected to a printer via WLAN.
- Emergency services only network
- Describes networks that are intended for, and limited to, emergency services. Select this type, for example, for connected ESS or EBR systems.
- Test or experimental
- Describes networks that are set up for testing purposes or are still in the setup stage.
- Wildcard
- Placeholder for previously undefined network types.
- HESSID mode
- Specify where the device gets its HESSID for the homogeneous ESS. A homogeneous ESS is defined as a group of a specific number of access points, which all belong to the same network. The MAC address of a connected access point serves as a globally unique identifier (HESSID). The SSID can not be used as an identifier in this case, because different network service providers can have the same SSID assigned in a hotspot zone, e.g., by common names such as "HOTSPOT". Possible values for the HESSID mode include:
- BSSID
- Select this item to set the BSSID of the device as the HESSID for your homogeneous ESS.
- User
- Select this item to manually assign a HESSID.
- None
- Select this item in order to not assign any homogeneous ESS and to isolate it from the device network.
- HESSID-MAC
- If you selected the setting user for the HESSID mode, enter the HESSID of your homogeneous ESS as a 6-octet MAC address. Select the BSSID for the HESSID for any access point in your homogeneous ESS in capital letters and without separators, e.g., "008041AEFD7E" for the MAC address 00:80:41:ae:fd:7e.
Important: If your device is not present in multiple homogeneous ESS's, the HESSID is identical for all interfaces
- ANQP profile
- Select an ANQP profile from the list. You create ANQP profiles in the configuration menu using the button of the same name.
- Hotspot 2.0 profiles
- Select the Hotspot 2.0 profile from the list. You create the Hotspot 2.0 profiles in the configuration menu using the button of the same name.
