Abstract

L'invention concerne un système et un procédé d'échange radioélectrique d'informations entre des dispositifs (6) situés sur le parcours et des véhicules (1, 2) se déplaçant le long d'un trajet, notamment d'un système de voies. Ledit système comprend un réseau radioélectrique, formé par des cellules radioélectriques, par le biais duquel les dispositifs (6) installés à demeure sur un parcours échangent des informations avec les dispositifs (4a) disposés dans les véhicules. La portée radioélectrique d'un dispositif (6) définit à chaque fois la cellule radioélectrique de ce dispositif (6), et les cellules radioélectriques des dispositifs (6) immédiatement voisins se chevauchent. Les véhicules passent d'une cellule à l'autre, les cellules radioélectriques étant disposées les unes derrière les autres, et dans la zone de chevauchement (A, B) de deux dispositifs (6) situés sur le parcours, le dispositif (4a) situé dans le véhicule établit une liaison radioélectrique supplémentaire avec le dispositif (6), situé sur le parcours, de la cellule radioélectrique immédiatement suivante. Pour garantir une transition sans interruption et si possible sans restrictions d'une cellule radioélectrique vers la suivante, notamment aussi en présence de réserves de bande passante réduites, le lieu (18, 19, 22) de changement de cellule radioélectrique est fixé au moyen des qualités de transmission locales déterminées à l'aide des véhicules accomplissant ce trajet, notamment à l'aide des véhicules (1, 2) qui précèdent.
