FIELD: physics, radio. ^ SUBSTANCE: invention relates to radio engineering and screening signals for a mobile communication system, particularly on an aircraft. The control device (100) is meant for shielding a room from input signals. To this end, the device has a receiver (104), an interference generator (105) and a transmitter (106). The receiver (100) receives transmission signals, from which a noise signal is determined in order to generate interference for the transmission signal. That noise signal is emitted by the transmitter (106). ^ EFFECT: efficient use of mobile terminals in a room. ^ 31 cl, 5 dwg |
