Abstract
A system for transmitting data using light includes a plurality of light sources configured to transmit light at non-overlapping wavelengths, processing electronics, and a diffuser configured to diffuse the transmission of light. The processing electronics assign the plurality of light sources to a plurality of channels, accept a data stream, allocate the data stream to the channels, and modulate a transmission of the light using the allocated data stream, where the allocated data used to modulate a first light source of the plurality of light sources is separate from the allocated data used to modulate a second light source of the plurality of light sources.
