Abstract
A system for locating an asset can include a first light fixture disposed in a volume of space and having a first transceiver, a first light source, and a first modulation circuit, where the first light source emits a first light output that defines a first line of sight, where the first modulation circuit generates and sends a first VLC signal that is part of the first light output, where a first light fixture location of the first light fixture in the volume of space is previously determined using the first transceiver during an auto-commissioning process. The system can also include a communication device associated with the asset, where the asset is disposed in the volume of space, where the communication device includes a second transceiver, where the second transceiver receives the first VLC signal from the first transceiver.
