Expand your service - Internet is always a plus
Laptops, tablet PCs or smartphones are not only offered at ever lower prices but are nearly always equiped with WLAN today. Even though GSM or UMTS data tariffs are constantly becoming cheaper, wireless LAN is a widespread, powerful and attractive platform for mobile Internet access because of its high transmission rates and simple configuration.

Whether in hotels, cafés, on company premises or on railway stations and airports: If you provide your customers with a public WLAN hot spot for Internet access, either free of charge or against payment, this constitutes an attactive service offer for your customers and gives you a competitive edge.
Teldat offers powerful WLAN systems for this purpose which are equally suitable for large or small hot spot environments. Thanks to their flexible and intuitive configuration options and their numerous features, the WLAN access points from Teldat are predestined for professional application.

The new bintec hot spot solution allows the operation of public hot spots for Internet access via WLAN – it is easy to set up, powerful, provides flexible configuration options and is compatible with the current legal requirements regarding data protection and telecommunications data retention.

The Internet access at the hot spot can be offered as free service or operated with a time- or volume-based ticket system. The solution is subsidiary-capable, which means that it can be offered on various sites and administrated centrally.

The bintec HotSpot Solution typically consists of a locally installed bintec RS232bw used as a hot spot gateway and of the Teldat HotSpot server that automatically manages the Internet access of the gateway.

An administration terminal – e.g. the reception desk PC in the hotel – is used for the administration of the operator account on the server: Logging of registrations, creation of tickets, statistical evaluation, etc.

If guests want to use the hot spot, they are initially lead to the login page of the operator. After sucessfully entering the login data of their tickets, they are granted unlimited Internet access for the agreed duration or data volume.

The hot spot gateway transfers the login data to the hot spot server via RADIUS. After successful login, the gateway forwards all Internet requests directly into the Internet. The duration of the connection is determined via the session time indicated in the scope of the RADIUS authentication. Moreover, the gateway makes periodical evaluations of the individual users, thus permitting volume-based session termination.

As shown in the above figure, the operation of the bintec HotSpot Solution requires both a HotSpot gateway and a HotSpot server. The server performs the hot spot user administration and stores all data needed for compliance with the legal provisions for telecommunications data retention.

The hot spot Server is located central in a modern high-availability computing center connected to the Internet via redundant data links. The utilization of the HotSpot  Server requires a HotSpot licenses.

When a user logs in for the first time or when a ticket expires (failed verification or authentication), the login window appears every time the user tries to access the Internet.

The left -hand frame of the login window is the actual login form. The right-hand frame contains a HTML web page** that can be programmed freely by the operator of the hot spot. It may contain e.g. operator information, general terms and conditions, banner ads or links to other web pages recommended by the operator.

**) Separate web space is required for the display – either on an external web server of your choice or your own web server in the local Intranet.

The hot spot tickets can be created using an Internetcapable PC with printer. The operator uses this PC to access the hot spot server and to create tickets, print, create and delete accounts, etc.

Hot Spot Gateway

• Simple user login via web browser
• Redirecting to an operator-specific login page during first login
• Registration via RADIUS authentication
• Multiple login of one user is prevented
• Time credits remain valid if the user logs off or the connection is terminated
• Re-usability of opened tickets
• The user needs to consent to the terms and condition during the login
• Optionally, the login process can be encrypted via SSL
• The WiFi link is unencrypted, but can be encrypted optionally with WPA-PSK
• A VPN connection between hot spot gateway and hot spot server is supported and recommended

Hot Spot Server

• Several locations can be configured for every customer (subsidiary support)
• Several tariffs can be confi gured for every customer (e.g. 24-hour ticket, 1-hour ticket or volume-based ticket)
• A separate administration section is available for each customer in order to create and manage the tickets
• Print function for the user tickets
• The HotSpot Solution supports the languages English, German, Netherlands, Italian, Spanish, French, Portuguese

In order to meet the legal provisions regarding telecommunications data retention, the MAC address, login and log-off time, as well as the used public IP address is stored for every user. This data is stored for 6 or 12 months according the country specific requirements. Information about the actually visited Internet pages is not stored for reasons of data protection.

Preliminary Note
In nearly all European countries, there are legal provisions regarding so-called data retention.

The providers of public Internet access are obliged to store specific data for a specific period of time and to provide it to the authorities on demand.

The explanations given below do not constitute legal advice. They merely provide general information. If required, legal advice should be obtained from a specialist lawyer.

The bintec hot spot server stores the following data:

• Start and end of the Internet session of a user (time and time zone). The user must be identified through an unambiguous ID.
• The public IP address used
• The place or SSID where the user started the session

This data is stored for 6 or 12 months according the country specific requirements and will be deleted afterwards. The stored data can be provided to the authorities on demand.

Notwithstanding the above mentioned provision, it is prohibited for reasons of data protection to store information regarding the transmitted contents or visited web pages that might permit conclusions about the user.

Notification Requirements for the Operation of a Hot Spot
In some countries, the operation of a public hot spot must be reported to the regulatory authority for telecommunications.

General Terms and Conditions
It is reasonable to request the hot spot user to actively confirm by clicking that he/she has read the general terms and conditions of the operator. The bintec hot spot solution is technically designed for this purpose. The general terms and conditions should for example include a remark that Internet access using the bintec HotSpot solution is transferred without encryption and that the users are personally responsible for the additional encryption of their data.
