Abstract

L'invention concerne un système de réseau maritime, sa structure de combinaison d'antennes et son procédé de communication. Le système de réseau maritime comprend: une première station de base à réseau sans fil et une deuxième station de base à réseau sans fil. La première station de base à réseau sans fil est installée sur un premier support maritime et échange un signal sans fil avec une troisième station de base à réseau sans fil installée sur la terre ferme selon un protocole de communication sans fil. La deuxième station de base à réseau sans fil, qui est installée sur un second support maritime, échange un signal sans fil avec la première station de base à réseau sans fil selon le protocole de communication sans fil et envoie des données à la troisième station de base à réseau sans fil par l'intermédiaire de la première station de base à réseau sans fil. Le support maritime peut être un navire, une plate-forme maritime ou une structure maritime flottante. L'invention permet aux dispositifs électroniques présents sur tous les supports maritimes de s'échanger des données par l'intermédiaire du système de réseau maritime de l'invention, et de se raccorder à Internet ou à un Intranet, ce qui améliore l'utilisation pratique du réseau sur le support maritime et assure sa mise en œuvre appropriée.
