Multi-wavelength visible light communications systems and methods

摘要

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.

1. A system for optically transmitting data, comprising:
a plurality of light sources configured to transmit light at non-overlapping wavelengths; processing electronics configured to:
assign the plurality of light sources to a plurality of channels;accept a data stream;allocate the data stream to the channels;modulate a transmission of the light using the allocated data stream, wherein 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; and an optical spreader configured to spread the transmission of light; wherein the modulation is configured to correspond to a transmission rate, wherein the transmission rate is less than an inverse of an optical multipath time in an environment.
