Lighting units 50a-d within a non-domestic building are each provided with a power-line communication (PLC) module. The power-line communication modulesestablish a mesh network within the power distribution circuit 10 of the non-domestic building, in which each lighting unit 50a-d acts as a node of the mesh network. The PLC mesh network additionally includes a head-end device to control routing across the network. The network facilitates "smart lighting" solutions. The lighting units may collect and transmit data relating to operating conditions of the lighting unit, or may incorporate sensors for determining occupancy. The lighting units may communicate with additional devices 42, 44 either wirelessly or using a wired connection. The lighting unit may receive commands from a computing device 42 or act as an access point for electronic shelf labels 44. |
