Title
(EN) MOBILE COMMUNICATION INSTALLATION AND RELATED METHOD OF EXCHANGING DATA
(FR) INSTALLATION DE COMMUNICATION MOBILE ET PROCEDE D'ECHANGE DE DONNEES AFFERENT
Abstract
(EN)
The subject of the invention is a mobile communication installation (1), characterized in that it comprises: a mobile body (2) furnished with a communication element (5) that can transmit and receive electromagnetic signals, said mobile body (2) moving along a pathway (3), a radiating cable (10) extending along said pathway (3), said radiating cable (10) comprising an electrical conductor (14) and being able to transmit and receive electromagnetic signals by way of said electrical conductor (14) along said pathway (3), said installation (1) being designed to exchange data between said radiating cable (10) and said mobile body (2) by transmitting through said radiating cable (10) or through said communication element (5) an electromagnetic signal coding said data and then receiving said electromagnetic signal by said communication element (5) or by said radiating cable (10), the communication link between said radiating cable (10) and said communication element (5) relying on magnetic coupling, said installation (1) comprising at least one optical fibre (11) intended to transport an optical signal coding said data, said radiating cable (10) and said communication element (5) furthermore being at most a distance apart equal to twice the wavelength of said electromagnetic signal.
