Des ing\u00e9nieurs du Laboratoire d'intelligence artificielle du Massachusetts Institute of Technology (MIT CSAIL) ont d\u00e9velopp\u00e9 une \u00ab surface intelligente \u00bb appel\u00e9e RFocus, qui \u00ab peut fonctionner comme un miroir ou une lentille \u00bb pour focaliser les signaux radio sur les appareils concern\u00e9s.<\/p>\n

\"Les<\/p>\n

Actuellement, il existe un probl\u00e8me certain pour assurer une connexion sans fil stable \u00e0 des dispositifs miniatures, o\u00f9 il y a pratiquement peu d'espace pour placer des antennes. Cela pourrait \u00eatre corrig\u00e9 par la \u00ab surface intelligente \u00bb RFocus, dont le prototype augmente la puissance moyenne du signal de pr\u00e8s de 10 fois, tout en doublant la bande passante.  <\/p>\n

Au lieu de plusieurs antennes monolithiques, les d\u00e9veloppeurs de RFocus ont utilis\u00e9 plus de 3000 antennes miniatures, compl\u00e9t\u00e9es par un logiciel adapt\u00e9, ce qui a permis d\u2019atteindre une telle augmentation significative de la puissance du signal. En d'autres termes, RFocus agit comme un contr\u00f4leur de direction des faisceaux, plac\u00e9 devant les appareils clients finaux. Les auteurs du projet estiment que cette matrice sera relativement peu co\u00fbteuse \u00e0 produire, \u00e9tant donn\u00e9 que chaque antenne miniature ne co\u00fbte que quelques centimes. Il est not\u00e9 que le prototype RFocus consomme moins d'\u00e9nergie par rapport aux syst\u00e8mes traditionnels. La r\u00e9duction de la consommation d'\u00e9nergie a \u00e9t\u00e9 possible gr\u00e2ce \u00e0 l'\u00e9limination des amplificateurs de signal dans le syst\u00e8me.<\/p>\n

\n\"Les<\/p>\n

Les auteurs du projet estiment que le syst\u00e8me qu'ils ont cr\u00e9\u00e9, disponible sous forme de \u00ab papier peint fin \u00bb, pourrait avoir de nombreuses applications, y compris dans le domaine de l'Internet des objets (IoT) et des r\u00e9seaux de communication de cinqui\u00e8me g\u00e9n\u00e9ration (5G), en fournissant un renforcement du signal transmis aux appareils utilisateurs finaux. La date \u00e0 laquelle les d\u00e9veloppeurs pr\u00e9voient de lancer leur cr\u00e9ation sur le march\u00e9 commercial n'est pas encore claire. D'ici l\u00e0, ils devront affiner le design du produit final, rendant le syst\u00e8me le plus efficace et attrayant possible pour les acheteurs potentiels.<\/p>\n
