The designed setup can transmit data at a rate of 16 kilobits per second for now.
Basem Shihada, an associate professor of Computer Science at the King Abdullah University of Sciences and Technology (KAUST), had been exploring data encoding into an artificial light source when he wondered if the same could be done with sunshine.
“I was simply hoping to use a cell phone camera to record a video of the encoded light stream to try to decode the video to retrieve the data; that’s when I thought, why not do the same with the sunlight?” Shihada said in a statement. “This would be much easier and can be done over the cell phone camera too. So we began to explore sunlight as an information carrier.”
