Abstract: The present invention relates to a device for allowing the use in an aircraft (A) of a personal radiocommunication means (R), in particular a mobile telephone. According to the invention, said device (1) comprises a first antenna (2) outside the aircraft (A), a second antenna (3) inside the aircraft (A) and a transponder (4) which comprises a first electromagnetic wave (OE) transmission and reception system coupled to the first antenna (2), a second electromagnetic wave (oe) transmission and reception system coupled to the second antenna (3), a central unit and means of authority for compelling the radiocommunication means (R) to operate at reduced power.

Abstract: The present invention relates to a device 1 for allowing the use in a aircraft A of at least one radio communication apparatus (R), such as mobile telephones. According to the invention, the radio communication apparatus (R) includes a first connection switch (MC1) between an information processing unit (2) and a transmit unit (3), and a connection switch (MC2) between the processing unit (2) and a receiving unit (5), and the device (1) includes a transmitter (8) transmitting waves (OE) out of the aircraft (A), a receiver (10) detecting waves outside the aircraft (A), and paths L1 and L2 respectively linked to the transmitter (8) and to the first connection switch (MC1) and to the receiver (10) and to the second connection switch (MC2).
