Apple working on zippy Li-Fi connectivity for the iPhone of the future?
With Li-Fi, the same light bulb that illuminates your living room can be used to transmit data to your phone. That is because Li-Fi uses visible light. And since nothing travels faster than light, Li-Fi offers an impressive theoretical throughput speed of up to 224Gb/sec.
Since iOS 9.1, the library cache files inside the OS mention "LiFi Capabilities" right next to other capabilities. With Li-Fi, the light from the source is received by a light sensor, which converts it into an electronic signal that is read by the phone. Don't expect Li-Fi to be offered in the Apple iPhone 7, however. The technology is still undergoing testing.
Imagine a world where your phone's internet connection comes from the technology first displayed on December 31st, 1879 by Thomas Edison. We could be just a few years away from this becoming reality.
