If you could cheaply make the lights transmit and receive, and if the data were recoverable at very low illumination, you could employ mesh routing -- there's often quite a bit of overlap from lightbulb to lightbulb.
But you're correct -- answering the LoS problem is significant. This could be very useful in many applications, but it's no silver bullet.
- aganick 15y agoWhile the LoS aspect is potentially desirable in specific applications, I agree that initially it can be perceived as a limiting factor. Researchers at Boston University,Rensselaer Polytechnic Institute, and Nakagawa Lab in Japan are working with software tools to characterize non LoS applications using reflective and refractive surfaces found indoors. A powerful system can be envisioned if someone managed to utilize these principles with a device that contains a receiver with a wide view.
