Smartphone companies are always looking at introducing new features to stay ahead in the race. And Chinese smartphone brand
is reportedly working on bringing a new technology called Li-Fi on its future smartphones.
For those unaware, Li-Fi is simply transferring data via light using LEDs. If Li-Fi is properly implemented, it can be 100 times faster data speeds than Wi-Fi. Interestingly, Li-Fi works even if the light source is dimmed to a level that it appears switched off to the naked human eyes.
Of course, Li-Fi is not a perfect technology yet but as per a report by LetsGoDigital Oppo already has published a patent in China to use Li-Fi in phones.
As per the patent revealed by LetsGoDigital, Oppo may use a small sensor on the top or back of the phone to provide Li-Fi functionality. The sensor looks very similar to a square camera lens but its main purpose is to provide faster internet connection.
According to the official Li-Fi website, Li-Fi can be expected to be integrated into smartphones within a few years. Other applications include, “Li-Fi can be used in hospitals for new medical instruments. Traffic lights can communicate with self-driving cars . Cars have LED headlights and LED rear lights that allow cars to communicate with each other and prevent accidents by the way they exchange information.”
While Wi-Fi will continue to exist, future phones may come with support for Li-Fi as well. This is because experts suggest that very soon we may hit the ceiling for Wi-Fi and capacity could become an issue.
Oppo will not just be using Li-FI for faster internet. “LiFi not only provides a significantly higher transfer speed than WiFi, the technology is also characterized by a lower latency (delay) -just like 5G-, it is also possible to transfer high-resolution images with a high frame rate, such as large video and audio files) - as stated in the patent description,” as per LetsGoDigital.
