- a base station and one or more (mobile) objects
- WLANs wireless local area networks
- the mobile objects (clients) search for a base station with a defined radio identifier (SSID: Service Set Identifier).
- SSID Service Set Identifier
- the radio identification must be known to the mobile object and the base station must either allow a group of clients with common characteristics or, for greater security, know the data of all clients, for which a database is necessary, and accept. Typically, this will connect multiple clients to the base station using the same SSID.
- the object of the present invention is achieved by a communication device for securely establishing a data communication between at least one mobile object and at least one access point or a base station, which is arranged in a monitored area or at least in the vicinity of the monitored area comprising a data carrier and a radio link, wherein the data carrier is fixed to the at least one mobile object and contains an identifier of the mobile object, wherein the identifier is readable by at least one reader arranged in the monitored area, and wherein the radio link in the Data exchange with the at least one access point is available if the identification of the mobile object can be read out by the at least one reading device.
- Data carrier in the context of the invention is any device that is able to store an identifier of the mobile object and to transmit this identifier to the reader when passing the reader, such as a bar code which can be read by a scanner (reader).
- the monitored area is the area in which the communication between the mobile object and the access point / the base station is established, wherein, in terms of radio technology, the area may be slightly larger than the area to be monitored.
- the identifier is an individual identifier of the mobile object with which the access point identifies the mobile object.
- the communication device makes it possible for security-critical projects to carry out a variable, unlimited number of mobile objects (clients) without manual intervention in the system components, such as the configuration of the mobile object or a base station, and a secure, undisturbed connection to one Access point (to the base station), without that a time-consuming effort, such as the formation of an ad-hoc network, arises.
- clients mobile objects
- base stations this allows a position-dependent assignment of the mobile object to a specific access point (a base station), ie the mobile object only receives the data related to its location.
- the communication device thus makes it possible to establish an individual, secure data connection to one or a plurality of access points and to allow the allocation of the access point depending on the position of the mobile object.
- the data carrier is preferably an RFID transponder and the reading device is a reading device which is suitable for reading out the identifier of the RFID transponder.
- the RFID transponder comprises a housing, an RFID chip and an antenna.
- the RFID transponder is a passive RFID transponder, which does not require its own power supply and is powered by the transmission power of the reader.

- the mobile object is preferably a vehicle, such as a motor vehicle, a driverless transport system, or a conveyor-mounted component in a factory.
- the monitored area is the road or a portion of the road on which the vehicle is moving or the conveyor belt or a portion of the conveyor belt on which the component is moved.
- the mobile object is a rail vehicle and the monitored area is a control point or a holding area of the rail vehicle, such as a signal system on the railway line, a railroad crossing or a platform / station.
- the rail vehicle consists of several (mobile) units (cars)
- a data carrier is preferably arranged on each of these mobile units (cars). This allows the assignment of the individual units even if the train is split and continues as two half trains (two mobile objects).
- the readers are in one embodiment in which the mobile object is a rail vehicle is suitably arranged at the platform edges (monitored area).
- At the beginning and at the end of the monitored area at least one reading device is preferably arranged.
- the beginning and end of the monitored area means the area in which the mobile object enters or leaves the monitored area.
- the communication device registers the passage of a mobile object (train) both when entering the monitored area, in the case of a rail vehicle as a mobile object, the rail area at the beginning of the platform, and when leaving the monitored area whose identifier reads out.
- the object of the present invention is achieved by a method of the aforementioned type, in which a data carrier which contains an identifier of the mobile object is read out by at least one reading device when a mobile object enters the monitored area the mobile object and at least one access point / a base station is set up after the identifier of the mobile object has been read by the reader and data is exchanged between the mobile object and the access point / base station via the radio link.
- a data carrier which contains an identifier of the mobile object is read out by at least one reading device when a mobile object enters the monitored area the mobile object and at least one access point / a base station is set up after the identifier of the mobile object has been read by the reader and data is exchanged between the mobile object and the access point / base station via the radio link.

- the mobile object brings along the identifier (SSID) itself, so that the
- the radio link between the (at least one) base station / the at least one access point and the mobile object is preferably disconnected when it is detected that the mobile object leaves the monitored area.
- an RFID transponder As a data carrier, an RFID transponder is preferably used. However, it would also be conceivable to use a barcode which delivers the identifier of the mobile object and is read out by the reading device.
- the reader programs the access point (WLAN access point), so it is not necessary to use a database or a larger server landscape.
- the radio connection is preferably established via a wireless local area network or via a Bluetooth connection.
- the method enables the establishment and execution of a wireless communication relationship according to IEEE Standard 802.11 (WLAN [Reference: IEEE Standards Association: 802.11-12 Wireless LAN 2012]) between a mobile object and an access point, by means of the mobile object defined and dynamically created in the access point for the duration of the communication relationship Service Set Identifier (SSID).
