Abstract

La présente divulgation concerne un réflecteur de signal sans fil utilisé pour réfléchir un signal sans fil d'un objet de réseau source à un objet de réseau cible. À cet effet, le réflecteur de signal sans fil utilise au moins deux éléments de détection adjacents pour déterminer une direction d'arrivée (DoA) du signal sans fil. La DoA déterminée du signal sans fil est ensuite utilisée pour commander correctement les propriétés réfléchissantes d'éléments réfléchissants dans le réflecteur de signal sans fil. Pour augmenter l'efficacité de commande des propriétés réfléchissantes, le réflecteur de signal sans fil peut en outre être pourvu d'au moins un élément de sondage configuré pour sonder l'objet de réseau cible avec un signal de référence. Au moyen de cette configuration, le réflecteur de signal sans fil peut commander les propriétés réfléchissantes des éléments réfléchissants sans avoir à communiquer avec une unité de commande centrale à distance. Ainsi, le réflecteur de signal sans fil peut fonctionner dans des environnements de transmission à changement dynamique.
