Visible Light indoor positioning through colored LEDs
The need to manage connectivity, when Internet access is granted indoor via Visible Light Communications, leads to acquire information about user position. This is useful for accessing the medium via space division multiplexing and/or giving rise to handover procedure or, more, providing access to location based contents, as for example, in large indoor environments as malls or museums. In this regard, we propose a localization mechanism that exploits the properties of metamerism so that the red, green, and blue components used by LEDs, provide the white light sensation to the human eye.
