Abstract

A control device that shields a room from incoming signals includes an interference device which is adapted for querying an interference signal for rendering a signal that enters a room unrecognisable by superposition with the interference signal.

Claims

1. A control device for shielding a room, the control device comprising:

a navigation device for determining aircraft data;

an interference device;

a transmitting device for transmitting an interference signal;

a data base for querying the interference signal;

wherein the database is connected to the navigation device;

wherein the interference device is adapted, for querying the interference signal with the help of the database, which interference signal corresponds to a condition currently present; and

wherein by the interference signal a signal entering the room can be rendered unrecognisable by superposition with the interference signal;

wherein for the generation of the interference signal the aircraft data are taken into account;

wherein the transmitting device is adapted to emit the generated interference signal.

2. The control device of claim 1, further comprising a connection to a local transmitting-receiving device, wherein the control device can influence the behaviour of a terminal via the connection.

3. The control device of claim 1, wherein the entering signal is selected from the group consisting of a GSM signal, CDMA signal, UMTS signal, GPRS signal, HSCSD signal, PDC signal, UWC signal, American mobile phone system signal, IS 95 A-signal and a wireless local area network-signal.

4. The control device of claim 1, wherein the interference signal is a noise signal.

5. The control device of claim 1, wherein the interference signal is selected from the group consisting of a GSM signal, CDMA signal, UMTS signal, GPRS signal, HSCSD signal, PDC signal, UWC signal, American mobile phone system signal, IS 95 A-signal and a wireless local area network-signal.

6. The control device of claim 1, wherein the control device is adapted for the integration in an aircraft.

7. The control device of claim 1, wherein the interference signal has a power;

wherein the power of the interference signal is adjustable such that the signal entering the room is covered up; and

wherein the power of the interference signal is adjustable such that the signal of a local transmitting-receiving device is receivable in the room.

8. The control device of claim 1, wherein the transmitting device comprises an antenna for emitting the interference signal.

9. The control device of claim 8, wherein the antenna comprises a leaky line antenna.

10. The control device of claim 1, further comprising

a coordination device;

wherein the coordination device comprises a flight attendant panel;

wherein the flight attendant panel is adapted for operating the coordination device and/or the control device.

11. A system for shielding a room, comprising:
