Title (EN) SPATIAL LOCATION INDOORS USING STANDARD FLUORESCENT FIXTURES
(FR) EMPLACEMENT SPATIAL INTÉRIEUR UTILISANT DES APPAREILS FLUORESCENTS STANDARD
Abstract: front page image
(EN)A system for identifying the location of the mobile device uses standard fluorescent light fixtures commonly found in indoor environments and detects minor variations in the light output of those fixtures caused by normal manufacturing variation. These variations are catalogued as identifying fingerprints together with location of the light fixtures to provide for navigation.
(FR)Système d'identification de l'emplacement du dispositif mobile utilisant des appareils d'éclairage fluorescents standards que l'on trouve couramment dans des environnements intérieurs et détectant des variations mineures de la sortie lumineuse de ces appareils provoquées par une variation de fabrication normale. Ces variations sont cataloguées en tant qu'empreintes d'identification avec l'emplacement des appareils d'éclairage pour assurer la navigation.
