LANCOM Public Spot Option
Wireless Public Spots are publicly accessible areas where users can use their
own mobile computers to access a wireless network (such as a company net-
work or the Internet).
Please note that operating a L-300 Access Point with the LANCOM
Public Spot Option (also referred to as a HotSpot) can be subject to
legal regulation in your country. Before installing a L-300 Access
Point, please inform yourself about any applicable regulations.
More information on this subject is available in our white paper
"Public Spot - Rechte und Pflichten eines Betreibers" available for

Wireless LAN technology is ideal for offering wireless Internet services to the
public in locations such as airports, railway stations, restaurants or cafes via
so-called HotSpots. The LANCOM Public Spot Option is intended for operators
of public wireless networks. It enables the easy installation and maintenance
of public HotSpots by providing LANCOM Access Points and LANCOM Routers
with additional functions for authentication and billing for public Internet ser-
vices.
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,
