Mecanisme de localisation de noeud sans fil utilisant la diversite de diagramme d'antenne pour ameliorer la precision des estimations de localisation

Wireless node location mechanism using antenna pattern diversity to enhance accuracy of location estimates

Abstract

A wireless node RF Fingerprinting location mechanism that uses multiple antenna patterns to enhance the accuracy of wireless node location in an RF environment. In one implementation, substantially non-overlapping antenna pattern diversity is used to provide a degree of sectorization in computing the estimated location of a wireless node.
La présente invention a trait à un mécanisme de localisation par prise d'empreinte radiofréquence d'un noeud sans fil utilisant plusieurs diagrammes d'antenne pour améliorer la précision de localisation de noeud sans fil dans un environnement radiofréquence. Dans un mode de réalisation, la diversité de diagrammes d'antenne sensiblement non chevauchants est utilisée pour fournir un certain degré de sectorisation dans le calcul de la localisation estimée d'un noeud sans fil.
