Systems and applications based on indoor positioning via led-lightingThe use of LED lamps available for 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.
