A vehicle (1) equipped with an on-vehicle telecommunication system (2; 16) having an electromagnetic field shielding case (7) installed in the vehicle (1) and for housing a user portable communication device (3), which has a first communication module (6) permitting, via a first antenna (6a), short-range radio-frequency transmission and reception, and a second antenna (5) permitting long-range radio-frequency transmission and reception to and from a remote radio-base station. The on-vehicle telecommunication system (2; 16) also has a third antenna (8) installed in the shielding case (7); a second communication module (9) connected to the third antenna (8) to permit, inside the shielding case (7), short-range radio-frequency communication with the first communication module (6) of the user portable communication device (3); and a user interface device (10), which is installed in the vehicle (1), is connected to the second communication module (9), and permits remote use by a user of the user portable communication device (3) to effect long-range radio-frequency transmission and reception to and from the remote radio-base station. <IMAGE> |
