LANCOM 3850 UMTS
Chapter 8: Options and accessories
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 Systems 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
Internet access services in hotels, restaurants, cafés, airports, stations, exhi-
bition centres or universities.
With the LANCOM Public Spot Option you extend a base station additionally
with these functions and upgrade it to a Wireless Public Spot.
