Abstract
Systems and methods are disclosed for use in conjunction with a standardized electrical connector of a conventional light bulb or tube with one or more light emitting diodes (LEDs) electrically coupled to at least one electrical connector compatible with a conventional light connector, wherein the LEDs include at least one multiband-type ultra-wideband (UWB) transceiver having one or more optical channels defined using one or more OFDM bands; and a controller coupled to the LEDs, the controller adjusting LED light output and communicating with the optical network using the optical transmitter and receiver. In other embodiments, the LEDs include at least one optical transmitter and receiver optically coupled to an optical network using at least one LED with a first mode to generate light and a second mode to receive optical transmissions using ambient light.
