Future iPhone or will use Li-Fi wireless transmission?

According to technology blog AppleInsider reported that users found in Apple recently released iOS system code library, which contains "Li-Fi" character, this seems to imply that: in iPhone wireless transmission standard in the future, Apple will use the Li-Fi visible light wireless communication technology to replace the current long-term use of Wi-Fi technology.

IOS code appears in the LiFiCapability character

Twitter user Chase Fromm, starting from iOS 9.1, apple iOS platform in the library cache file in a statement and other hardware and software compatibility statement, also appeared in the "LiFiCapability" (LiFi compatible) function statement. AppleInsider confirms this.

Li-Fi visible light wireless communication mode with the traditional infrared remote control is completely different, the working mechanism of Li-Fi transmission: data is transferred to a light source, was quickly transmitted in the form of optical signal, the optical sensor receives the light signal into electrical signals after restructuring.

Different from the TV remote control, Li-Fi uses visible light, and the way the data can not be felt in the sense of the human eye, which means that the user's hall can be used as a common data access point. Theoretically, the data transmission rate in Li-Fi mode can reach 224GB/ seconds.

At present, Li-Fi technology is still in the experimental stage, but many companies are trying to commercialize this technology. At least one company, that is, the Velmenni company in India has begun to measure the Li-Fi technology.

In addition to the introduction of optical communication technology in the field of software, in fact, Apple has also carried out in the field of optical communications products R & D. In early 2013, apple gained a "light modulation" image sensors using patented technology, sensor mentioned in the patent, can convert in image capture and data capture mode, allowing the implementation of optical communication in the case without additional hardware. Apple envisions this particular system for indoor use, but overall, the patent is also a high bandwidth application device.
