Authentication and billing for individual users is implemented with user-
friendly Web pages, enabling client PCs with a WiFi-certified wireless card
(el.g. AirLancer) and standard Internet browser to go directly online.
The LANCOM Public Spot Option is the ideal solution for public wireless LAN.
Wireless LAN are very well suited for company networks and for wireless net-
working in the home. However, for public access services the standard setup
lacks important mechanisms for authentication and billing of individual users
(AAA — authentication, authorization, accounting). This is remedied by the
LANCOM Systems Open User Authentication (OUA), the core component of
the LANCOM Public Spot Option. OUA implements the authentication of all
wireless clients by user name and password. It checks the authorization of
each user with a RADIUS server. Accounting data (online time, volumes) on a
per user and per session basis can be passed on to the central RADIUS server.
All the client PC needs is a wireless card (el.g. AirLancer), TCP/IP, and an Inter-
net browser. No further software is required. The Public Spot Option is opti-
mally suited for setting up wireless Internet access services in hotels,
restaurants, cafes, airports, railway stations, exhibition grounds or universi-
ties.
The LANCOM Public Spot Option equips an access point with these functions
and upgrades it to a wireless Public Spot.
