1. An apparatus for detection of a communication channel having a frequency band in which radio signals are transmitted from different radio signal sources inside a cabin, said apparatus comprising:

  • a wide band antenna to receive the radio signals transmitted inside the cabin;

    a plurality of demodulators, each of which demodulate the radio signals received by said wide band antenna in an associated frequency range of the respective demodulator; and

    a configuration logic for establishing whether, in a frequency band within a frequency range demodulated by said demodulators, radio signals are being simultaneously transmitted by different radio signal sources,wherein said configuration logic establishes, in an operational detection mode, whether, in a frequency band of the communication channel of an internal on-board radio system, a radio signal from another radio signal source is being transmitted, and allocates to the other radio signal source a different frequency band within the demodulated frequency range.
