The general objective is to obtain an indoor positioning system that is capable of estimating the position of “smart” devices or of simple detectors designed for that purpose (receivers) from the emission of codes embedded in the lighting light of a room/building. The achievement of this system shall allow the development of multiple applications for the set-up of routes and help to guide. The use of LED lamps available for the lighting of different parts of a building or room in such a way as to allow the transmission of very high-frequency codes non-perceptible by humans together with the illumination lights. These codes (one unique code for each LED lamp) will be decoded by light detectors included in smart-devices, or by detectors designed particularly for this purpose. From the code information, the device positioning can be determined with high precision.
