The future of technology is the 5Gbut who said it has to be? Indeed 5G is a technology for mobile data, but what about passing data over the air? We all know the WiFi signal but we also know that there is a kind of evolution, namely the LiFi signal. We don't hear about it very often but in the future it will be within everyone's reach, as was WiFi (and still is). It is a technology that allows a data passage up to 100 times faster e Oppo he's working on it.
A patent shows us how Oppo is working on LiFi technology: X100 speed in data passing
From a patent that the team of LETSGODIGITAL we learn about Oppo's interest in this very interesting, albeit distant, technology for passing data via wireless. A 2.0 WiFi if we want the bran plans to integrate into its devices in the future. The most promising alternative to WiFi is Li-Fi (Light Fidelity), but what's the difference between the two? Radio waves are used with WiFi via a router while with LiFi transmits light via an LED lamp. Ultimately where WiFi uses radiation, LiFi uses light.
Last month Oppo published a patent in which it mentions this technology and shows the first eligible smartphone to integrate it. IS a modern smartphone with narrow edges and a full screen design, without contamination of holes and notches. No front camera is visible and in fact it features a pop-up mechanism as it is fashionable now, albeit without shark fin like Reno 2. While on the front, however, we have no big news compared to the devices we see daily, the back is the one that interests us the most. As we can see in fact there is a square to the left of the photographic section. It is through it that the St.all LiFi is captured from the device.
It is basically a photodetector which converts changes in amplitude into an electrical signal to enable LiFi communication with the smartphone. The device could be part of the Reno series in the future and to suggest it is the so-called O-dot at the bottom of the rear cameras. In a second patent called "LiFi device and its projection system“, It is widely discussed how Oppo wants to apply LiFi in mobile devices. The patented LiFi device can be installed in any smartphone and consists of a housing, a printed circuit board and a LiFi module for signal reception.
Not only does LiFi mean significantly faster transfer speeds than WiFi, it also features a lower latency than standard WiFi. It is also possible transfer high resolution images with a high frame rate.
All good, but what is LiFi? Let's try to clarify
When we use the signal WiFi, there are often some problems with which we have to interface. This standard it has limits as regards the "range" and above all the antennas necessary for communication consume a lot of energy. Furthermore, the privacy issue related to radio waves is much discussed as they can be intercepted by malicious people. The LiFi standard (VLC PAN IEEE 802.15.7) seems to solve most of these problems.
First of all, it has a greater “range” and power, such that one can be reached transmission speed up to 15 Gbps. The lack of signal problem would seem not to exist with this standard since it is not slowed down even in high-density areas, perhaps areas where users use the internet at the same time.
An interesting curiosity: the LiFi signal can also be used under water and that is why the US Navy is very interested in this technology.
