A merchandiser communication system including a first plurality of merchandisers arranged in a first row and a second plurality of merchandisers arranged in a second row. Each of the merchandisers includes a light assembly coupled to a case to illuminate a product display area, a light sensor coupled to the case to detect light pulses, and a microcontroller. The light sensor is in visual proximity with one or more of the adjacent merchandisers located across the aisle. The microcontroller is in electrical communication with the light assembly and the light sensor to operate the light assembly to encode the signal in light pulses of the light assembly that are not detectable by a human eye. The communication system also includes a visible light-based communication network in communication with the merchandisers and is operable to communicate the encoded light pulses among the merchandisers via the light assemblies and the light sensors.
