Abstract

La présente invention concerne une technologie qui permet de fournir facilement des informations de position. Selon l'invention, dans un procédé exécuté au moyen d'un système de fourniture d'informations de position doté d'une pluralité de modules d'étiquettes, lesquels transmettent des étiquettes sans fil, et d'un serveur d'informations de position, qui fournit des informations de position conformément aux étiquettes sans fil, les modules d'étiquettes convertissent une lumière d'éclairage provenant d'un appareil d'éclairage en énergie électrique et transmettent des étiquettes sans fil à une plage conformément à la plage de rayonnement de lumière d'éclairage au moyen de l'énergie électrique, le serveur d'informations de position reçoit une requête pour des informations de position correspondant aux étiquettes sans fil à partir d'un terminal utilisateur qui a reçu les étiquettes sans fil, se réfère à une base de données d'informations de position qui enregistre la correspondance entre les étiquettes sans fil transmises dans une plage correspondant à la plage d'éclairage par l'appareil d'éclairage et des informations de position relatives à la position d'installation de l'appareil d'éclairage, extrait les informations de position correspondant à l'étiquette sans fil vis-à-vis de laquelle la demande a été reçue en provenance du terminal utilisateur, et transmet au terminal utilisateur les informations de position extraites conformément aux étiquettes sans fil.
