Abstract:
Techniques are disclosed for spatially resolving received light-based communication (LCom) signals. In an example case where one or more LCom signals are in the field of view (FOV) of an LCom receiver, the image representing the FOV may be captured and segmented into non-overlapping cells, such as hexagonal, triangular, rectangular, or circular shaped cells. Each LCom signal may be interpreted as a unique pixel cluster comprising one or more of the cells. In some cases, the LCom signals in the FOV may be received from multiple LCom-enabled luminaires and/or a single LCom-enabled luminaire having multiple light panels. The benefits of being able to spatially resolve received LCom signals may include establishing a link with multiple LCom signals within the FOV of a receiver without conflict and/or determining the location of those LCom signals, improving signal to noise ratio, augmenting position information, enhancing sampling frequency, and improving communication speed.
