LIGHT-BASED COMMUNICATION TRANSMISSION PROTOCOL
First Claim
1. A system comprising:
- a first solid-state luminaire configured to emit a first pulsing light signal encoded with data;
a second solid-state luminaire configured to emit a second pulsing light signal encoded with data; and
at least one controller configured to control a color of light emitted by the first solid-state luminaire and a color of light emitted by the second solid-state luminaire.

Abstract
Techniques are disclosed for providing light-based communication (LCom) between a receiver device and one or more transmitting LCom-enabled luminaires. In accordance with some embodiments, LCom data to be transmitted may be allocated over multiple colors of light output by multiple LCom-enabled luminaires and transmitted in parallel across the multiple colors of light using a time division multiple access (TDMA) scheme. In some cases, the disclosed techniques can be used, for example, to allow for multiple LCom-enabled luminaires to communicate simultaneously over multiple active LCom channels with a single receiver device. In some instances, the disclosed techniques may be used, for example, to provide channel redundancy that facilitates successful completion of LCom data transmission when an LCom channel is broken. In some instances, the disclosed techniques may be used, for example, to provide more accurate positioning for indoor navigation.
