IOS code contains references to LIFI data communication via light




In iOS 1.9’s code with references to LIFI. Apple seems thereby working to support the data communications via light, although the technique is still largely in the experimental stage.

In iOS 1.9 is a library cache file in which the term appears LiFiCapability, discovered a Twitter user along with AppleInsider. The manufacturer appears to be worked on LIFI application. In this technique, the flash of visible light of a LED-lamp is modulated so that a data signal can be transmitted to a receiver. The flashes are to the human eye can not perceive.

The advantage is that a simple and inexpensive high-speed network can be established. The disadvantage is that the range is limited and the source must be visible to the receiver. Researchers have been using the technique speeds of hundreds of gigabits managed to get, but applications for consumers, there are hardly any.

During CES 2016 showcased the company Basic6 a geo-li-fi application, which stores or museums can identify the location of visitors based on li-fi, and a trigger can issue based on the lamp which illuminates their mobile device.

The inventor of li-fi is Harald Haas, a German professor who is affiliated with the University of Edinburgh. He demonstrated the technology itself in 2011 during a TED talk and had recently seen that it works in combination with solar panels.
