Abstract

L'invention porte sur un système et sur un procédé de communication sans fil d'un dispositif mobile (12) à une station de récepteur à distance (14). Le système comprend un contrôleur (22) configuré pour surveiller un état du dispositif mobile (12) et, lors d'un événement d'initiation, initier un processus de transfert de données pour communiquer de façon sans fil des données à la station de récepteur à distance (14). Le système comprend également un modem en bande de conversation (24) qui, lors de l'initiation du processus de transfert de données, est configuré pour recevoir des données pour un transfert vers la station de récepteur à distance (14), diviser les données de source en des paquets de source de collection, et coder les données à l'aide d'un protocole de codage de code de type fontaine pour former une série de paquets codés. Le modem en bande de conversation (24) est également configuré pour transmettre la série de paquets codés à la station de récepteur à distance (14) en tant que salve comprenant la totalité des données de source et transmettre de façon répétée les paquets codés jusqu'à réception d'une indication selon laquelle la série de paquets comprenant la totalité des données de source a été reçue au niveau de la station de réception (14).
