Abstract

La présente invention concerne un procédé et un dispositif de positionnement sans fil très précis tels que : l'intensité d'au moins un signal émis à partir d'au moins un nœud fixe est mesurée; la position relative d'un nœud mobile est estimée; un motif de variation d'au moins une intensité de signal en fonction du changement relatif de positon du nœud mobile sur de multiples points temporels est généré à partir de ladite intensité de signal et de la position relative du nœud mobile; et la position absolue du nœud mobile est estimée sur la base d'une comparaison entre le motif de variation de ladite intensité de signal et une carte d'un motif de répartition d'intensité de signal au niveau d'une zone dans laquelle est positionné le nœud mobile. Ainsi, la position du nœud mobile peut être estimée avec précision même lorsqu'un environnement sans fil change, et la position du nœud mobile peut être estimée avec précision sur une large zone en utilisant un signal sans fil ne présentant presque aucun changement d'intensité du signal.
