Abstract

La présente invention concerne un terminal de communications sans fil et un procédé de traitement de données, comprenant une pluralité de modules radioélectriques (RF) ayant des fréquences radio différentes, et une pluralité de frontaux sans contact (CLF) et de gestionnaires de frontaux qui ne sont pas sans contact, chaque élément de cette pluralité correspondant à un module RF. Les modules RF sont destinés à recevoir des signaux RF sans contact ayant les mêmes fréquences radio qu'eux, et à envoyer un signal radioélectrique sans contact à un CLF correspondant. Un CLF est conçu pour recevoir un signal RF sans contact envoyé par un module RF correspondant audit CLF, pour moduler/démoduler le signal RF sans contact afin d'obtenir un premier signal modulé/démodulé, et pour envoyer le premier signal modulé/démodulé au gestionnaire de CLF, ce premier signal modulé/démodulé contenant des données à traiter. Un gestionnaire de CLF est prévu pour recevoir le premier signal modulé/démodulé envoyé par le CLF, et pour traiter les données à traiter contenues dans le premier signal modulé/démodulé. Grâce aux solutions apportées par les modes de réalisation de cette invention, les données en attente de traitement contenues dans des signaux sans contact de diverses fréquences radio peuvent être traitées sur un seul terminal de communications sans fil.
