Apple iOS Code Hints of Integrating Li-Fi Applications in Future Devices

A sharp eyed Twitter user has spotted a code implying Li-Fi functions might be incorporated in later generation Apple iOS, reported TechRadar and other media.

The Twitter user Chas Fromm found the code “Li-Fi Capability” among the latest version of iOS 9.0 coding update, which has also been confirmed by reports from Apple Insider.

A snap shot from Chase Fromm’s Twitter account below highlights the coding.

LEDinside has previously introduced Li-Fi technology, which can be generally explained as technology that involves transmitting electronic data using light signals.

The light source used in Li-Fi technology could be LEDs that transmit the data through a specific wavelength, at a modulation rate that is not visible to the human eye.

Lasers are thought to be a potential light source for Li-Fi applications.

According to Apple Insider report, the theoretical output capacity for Li-Fi is about 224 gigabits per second.

Even though Li-Fi is still pretty much a concept and prototype product, a couple of companies are working to commercialize the technology. Indian-based company Velmenni has even started real-world testing.

In addition to the software references, Apple has been working on hardware implementations for light-based wireless data transfer, or optical wireless communication.

The report noted the Cupertino company had filed for a related patent in 2013 that describes the method of "optical modulation using an image sensor." The sensor could switch between image capture and data capture modes, which allowed for light capabilities without adding any extra hardware.

Apple visualizes the system will be applied for indoor location, but it is also applicable in high-bandwidth applications.
