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. |

DETAILED DESCRIPTION The object of the present invention is to remedy these drawbacks.
It relates to a simple and inexpensive device for allowing the use in a standard and risk-free manner, in an aircraft, of at least one personal radiocommunication means of the type alluded to above, in particular a mobile telephone.
For this purpose, according to the invention, said device is noteworthy in that it comprises: at least one first antenna able to transmit and pick up, outside the aircraft, electromagnetic waves respectively picked up and transmitted by satellite networks or ground networks, called outside networks; at least one second antenna able to transmit and pick up, inside the aircraft, electromagnetic waves respectively picked up and transmitted by a passenger's radiocommunication means; and a transponder which comprises : a first electromagnetic wave transmission and reception system coupled to said first antenna; a second electromagnetic wave transmission and reception system coupled to said second antenna; a central unit which sends, if relevant after matching, signals received by one of said first and second transmission and reception systems to the other transmission and reception system; and means of authority for compelling said radiocommunication means to operate at reduced power and for controlling the operation thereof.
Thus, by virtue of the invention, any passenger in the aircraft can use a personal radiocommunication means, for example a mobile telephone or a portable terminal, that is to say he can connect up to a telephone network, under the same conditions of service as if he were located on land in his office or his car, and do so without danger of interference with on-board electronic systems, since the operating power of said radiocommunication means is lowered in such a way as not to allow such interference.
Moreover, by virtue of said device in accordance with the invention, the possessor of such a radiocommunication means can not only call an opposite party, but also be called on his personal number, under the same conditions as on the ground, this being irrespective of the geographical position of the aircraft
