Abstract
A system of networked lighting devices includes a central controller and a group of lighting devices. The central controller includes a processor, first and second communication interfaces, various lighting devices and a communication link. The first communication interface includes input ports and a multiplexer configured to receive signals from the input ports and combine the received signals into a multiplexed signal. The second communication interface includes one or more antennas and is configured to receive the multiplexed signal from the multiplexer and transmit the multiplexed signal via the antenna(s). Each lighting device includes a fixture controller, one or more lighting modules, and a communication interface. The communication link transmits the multiplexed signal between one or more of the lighting devices and at least one of the communication interfaces of the central controller.
