5.3.1.4 Configuring WLAN Hotspot Support

The access point enables hotspot operators to provide user authentication and accounting without a
special client application. The access point uses a traditional Internet browser as a secure
authentication device. Rather than rely on built-in 802.11security features to control access point
association privileges, configure a WLAN with no WEP (an open network). The access point issues
an IP address to the user using a DHCP server, authenticates the user and grants the user to access
the Internet.
When a user visits a public hotspot and wants to browse to a Web page, they boot up their laptop
and associate with the local Wi-Fi network by entering the correct SSID. They then start a browser.
The hotspot access controller forces this un-authenticated user to a Welcome page from the hotspot
Operator that allows the user to login with a username and password.
The access point hotspot functionality requires the following:
• HTTP Redirection - Redirects unauthenticated users to a specific page specified by the
Hotspot provider.
• User authentication - Authenticates users using a Radius server.
• Walled garden support - Enables a list of IP address (not domain names) accessed
without authentication.
• Billing system integration - Sends accounting records to a Radius accounting server.

hotspot), while TCP/IP packets are redirected to the port on the subnet to which the WLAN
is mapped. For WLANs not hotspot-enabled, all packets are allowed.
