ABSTRACT:
This invention relates to the zonal transmission of data by the modulation of the light output of arc lamps or discharge lamps; including the visible or invisible light output of fluorescent lamps, mercury vapor lamps, high or low-pressure sodium lamps, metal-halide based lamps, or other arc or discharge lamps. The method results in an easily installed, easily maintained, and economical to purchase, optical-wave communications system which exploits the existing infrastructure of a building or facility to facilitate the transmission of data in individual zones; thereby facilitating the transmission of wide-area as well as zonal-specific data to compatible receivers, and further facilitating the determination of location of remote devices or users, and the delivery or exchange of information or data, utilizing limited range transmission techniques.
