A retail merchandising system includes a plurality of gondolas positioned in a retail space, a plurality of visible light communication (VLC) sources positioned in the retail space, and at least one VLC sensor disposed at a fixed location relative to each of the plurality of gondolas. The plurality of VLC sources and the at least one VLC sensor are configured to cooperatively identify a location of the gondolas in the retail space. With pre-stored planograms and the locations of the store gondolas, product locations can be readily determined. Additionally, the system can determine customer locations and communicate with customers and/or track customer activity.
