 OPPO Tanghai: 5G will change the shape of intelligent terminal and keep it running without pressure


Tang Hai, Chief 5G Scientist and Head of Standards Research Center of OPPO Research Institute

More than half of 2019, more than 20 operators have announced the provision of 5G commercial services, and more than 20 manufacturers of mobile phones and other terminals have or are about to produce 5G terminals. Therefore, 2019 is known as the 5G Year of Commerce.

OPPO, as one of the head brands of smartphones in China, has just launched Reno5G version of its first 5G commercial mobile phone. At the same time, OPPO has also announced the establishment of 5G Experience Center with China Unicom, and delivered OPPO Reno 5G mobile phone to China Unicom. For the upcoming 5G + era, OPPO has made full preparations in standard setting, product development and application scenario exploration.

Tang Hai, head of the Standards Research Center of OPPO Research Institute and chief 5G scientist, recently interviewed Netease Mobile, saying that 5G may change the shape of smart terminals in the future. Tang Hai believes that 5G will mature faster than 4G, but at this stage, the construction of 5G network still needs the cooperation of the industry to improve.

The shape of smart terminals may change

Compared with 4G, 5G network can provide several times less downlink speed, tens of times more downlink speed and milliseconds delay time. In this regard, Tang Hai said that many applications that were difficult to achieve on previous 4G are possible in the future, including 360-degree VR, AR, 4K, 8K and even higher ultra-high-definition video playback, and even future virtual reality, even holographic images, etc. Now.

The advantage of low latency can also be perceived by consumers: The most common interactive application is the operation of the game, and the direct response of the operation experience to any input of the player will be greatly improved. If the network condition is good, the existence of network delay can not be detected at all. Another notable example is that in VR applications, low latency can significantly reduce vertigo.

It can be seen that the application of 5G ultra-high downlink rate on smartphone is not very clear at present, and many functions will appear on different terminals in the imagination. It is also for this reason that 5G is likely to revolutionize the smart devices in peoples hands. It is worth looking forward to what functions and shapes the smart phone will integrate in the future.

5G is a very good highway. There will always be better cars running on it when it is repaired. It may still be mobile phone form now, but I believe that more new or enhanced devices will appear in the future.

Equipment will not have endurance pressure

Even without considering the power pressure caused by 5G RF, simply reading and writing more data in flash memory at the same time will increase the power consumption to varying degrees. The power consumption caused by the increase of antenna and speed is one of the difficulties that mobile phone manufacturers need to overcome. The downlink speed of OPPOReno 5G version is 7.9 times higher than that of 4G version, and the power consumption of downloading 1GB files is less than 1%. This data can perform well in the current environment. Tanghai still has full confidence in the future ultra-high speed 5G bandwidth.

Tang Hai said that with the optimization of semiconductor manufacturing process, the maturity of mobile power control strategy, 5G network optimization, and the joint optimization of mobile phone manufacturers, network manufacturers and operators, the users endurance experience will be guaranteed.

Before the breakthrough of battery technology, it is difficult to make a qualitative leap in the life of smartphones. With the advent of 5G era, it is not easy to ensure the current level of endurance.

The 5G network needs the cooperation of the industry to improve

The domestic 5G network, which is still in the pilot stage, is very unstable at the present stage. The 5G signal is hard to find and the bandwidth is unstable. Rate is closely related to network conditions and spectrum bandwidth.

Communication is an end-to-end system, which is decided by terminals, networks, operators and other major projects. Only when every link is optimized in place, can the real 5G experience be realized. Tang Hai said that OPPO will continue to invest in technology and innovation, and make more contributions to mobile phones, applications and user experience, but the whole network experience is not unilaterally determined by mobile phone manufacturers.

In fact, not only network deployment, 5G mobile phone development is also in its infancy. Including R&D of radio frequency technology, R&D of mobile phone structure design, R&D of stack design, battery optimization and other issues need to be solved urgently.

5G will still mature faster than 4G. Although 5G development is still in its early stage globally, 5G deployment will be significantly faster than 4G in terms of the enthusiasm of operators and terminals. Domestically, the three major operators have announced 5G business plans and launched 5G pilot projects in more than a dozen cities in collaboration with mobile phone manufacturers. Internationally, Swiss operators have achieved 5G commercial use, and OPPOReno 5G version has even become the first official commercial 5G mobile phone in Europe. Tang Hai believes that in the next 1-2 years, many markets will gradually enter the 5G formal commercial stage, and the whole industry is making great efforts to promote and promote the further maturity of 5G ecology.
