Creating a Hotspot 2.0 Service
“Hotspot 2.0” is a newer Wi-Fi Alliance specification that allows for automated
roaming between service provider access points when both the client and access
gateway support the newer protocol.
Hotspot 2.0 aims to improve the experience of mobile users when selecting and
joining a Wi-Fi hotspot by providing information to the station prior to association.
This information can then be used by the client to automatically select an appropriate
network based on the services provided and the conditions under which the user
can access them. In this way, rather than being presented with a list of largely
meaningless SSIDs to choose from, the Hotspot 2.0 client can automatically select
and authenticate to an SSID based on the client’s configuration and services offered,
or allow the user to manually select an SSID for which the user has login credentials.
ZoneDirector’s Hotspot 2.0 implementation complies with the IEEE 802.11u stan-
dard and the Wi-Fi Alliance Hotspot 2.0 Technical Specification.
lid The Location ID of the Hotspot service.
uip The client’s real IP address. In a Layer 3 NAT environment, the
client’s IP address will be translated to the gateway’s IP address
when logging to the Hotspot service. In this case, the login request
has to include the client’s real IP address to be handled properly.
dn The domain name of the ZoneDirector. The domain name is
obtained from the SSL certificate when importing a certificate to
ZoneDirector.
uid The user’s login ID (passed in the UAM login form’s user name
parameter).
client_mac The client’s MAC address.
SSID The SSID to which the client is associated.
Loc The location name defined in the AP settings.
vlan The client’s VLAN ID.
reason The reason for redirection; can be empty for first redirect, failed for
auth failure, or logout when client logs off.
