According to LetsGoDigital reports, in December 2019, Guangdong OPPO Mobile Communications Company applied for a smartphone appearance patent from the State Intellectual Property Office. The patent was released on July 31, 2020, and includes 24 product appearance drawings and a short description. Importantly, the patent shows that the smartphone supports LiFi (Light Fidelity, visible light wireless communication) connection technology.
Compared with Wi-Fi that uses radio waves, optical wireless communication uses photoelectric signals as a medium for communication. According to the patent, this smartphone looks like a full-screen smartphone with a narrow bezel design. The back is a dual-camera and has the iconic Reno series of scratch-resistant small round bumps, but the front camera is not visible. Open holes.
This is a smart phone with a narrow bezel and a full-screen design, using a pop-up camera. And we can notice that there is a blue rectangular area marked near the pop-up camera and the rear camera module. This rectangular area is used as a receiver. It can realize a smart phone by converting light pulses of different rates into transmission signals. LiFi communication.
The top and bottom are also equipped with microphone openings, and the bottom is equipped with speakers, SIM card slot and USB-C charging/data port. The power button is located on the right side of the fuselage, and the volume adjustment button is expected to be on the left side of the device. Interestingly, three days after submitting the design patent, OPPO also filed a utility model patent application in China (now included in the WIPO database), which details the composition and application of the LiFi device.
As part of the VLC PAN IEEE 802.15.7 standard, LiFi has completed a transmission test of not less than 10 Gbps in a laboratory environment (approximately 100 times that of the current Wi-Fi wireless network).
Although the WiFi we are using can meet the network connection requirements, this technology also has many problems. First of all, routers and other equipment required for WiFi connection consume a lot of energy, while LiFi only needs to be used where there is light. With the popularity of LEDs, LiFi will be more energy-efficient and efficient.
Nowadays, in homes, workplaces and public buildings, the wireless network technology 802.11 series (the latest standard is Wi-Fi-6) has become quite popular. But in the future, by adapting LEDs and systems, it is expected to further reach 15Gbps, allowing more people to transmit data in a high-density environment. Of course, LiFi is not without its shortcomings. While ensuring privacy, its signal coverage is only about 10 meters, while Wi-Fi is 32 meters.
Finally, according to the official statement, LiFi will be integrated into smartphones within a few years. And as early as a few years ago, a French company showed a LiFi smartphone model. However, no mobile phone manufacturer has dared to use this technology on mass production machines yet, so will OPPO be the first?
