LANCOM Public Spot Option
Wireless public spots are publicly accessible points, at which users with their
own mobile computers can dial wirelessly into a network, usually into the
Internet.
The Wireless LAN technology is ideally suitable to offer wireless Internet serv-
ices to the public at places such as airports, hotels, stations, restaurants or
cafés, so-called Public Hot Spots. The LANCOM Public Spot Option is intended
for operators of public wireless networks, and unveils additional functions for
authentication and billing of public Internet services for the LANCOM Wireless
DSL base station, thus enabling a simple set-up and maintenance of public
hot spots.
The authentication and billing of the individual users is realized via user-
friendly web sites, so that client PCs with a Wi-Fi certificated radio card (e.g.
AirLancer) and a standard Internet browser can directly go online.
The LANCOM Public Spot Option is the optimal solution for public Wireless
LANs. Wireless LANs are very suitable for company networks and for wireless
networking at home. But for public access services, there is a lack of mecha-
nisms for authentication and billing of single users (AAA - Authentication /
Authorisation / Accounting). This lack remedies the LANCOM Open User
Authentication (OUA), the main part of the LANCOM Public Spot Option. The
OUA procedure realizes the authentication of all wireless clients via user name
and password, and checks the authorization of single users via RADIUS.
Accounting data (online time and data volume) can be transferred per user
and per session to a central RADIUS server. Client PCs need only radio card
(e.g. AirLancer), TCP/IP and an Internet browser. Additional software is not
needed. Therefore, the public spot option is ideally suitable to install wireless
