Abstract
Techniques for determining a position of a mobile device using visible light communication signals are provided. An example device includes memory and a processor configured to in response to a determination that at least one first image of a plurality of images stored in the memory is of a modulated light signal transmitted by a light source and comprising coded information, determine a spatial location of a reference point of the light source based on the coded information, in response to a determination that at least one second image of the plurality of images is of an unmodulated light signal emanating from the light source, determine an image location of the reference point of the light source in the at least one second image, and determine a position of the mobile wireless communication device based on the image location of the reference point and the spatial location of the reference point.
