 Those who have been black for 4G are now questioning 5g


The Internet has changed almost everyone. The Internet life is life itself - the 4G era has profoundly confirmed these two words.

From 2013 to 2019, in just seven years, more powerful network technology has made a strong change in the communication between people, people and things, people and the world. People are no longer closed, things are no longer rigid, the world is no longer far away, life is no longer single line. Online entertainment, consumption and communication are more direct, convenient and diverse, and peoples spiritual life has been greatly enriched.

In the 5g era that is about to open, these two sentences obviously have richer meanings and broader imagination space.

The world is preparing for 5g. 5g is not only the hot discussion center in the past year, but also the starting point of imagination in the next decade: South Korea is the first commercial company, and China and the United States are involved in this; the three major operators in China jointly released 5g packages on October 31, 2019, with a total number of appointments exceeding 10 million, and the base station construction completed the established goal in advance. For 5g, 2020 is not only the beginning of all-round business war and technology battle, but also the beginning of all good imagination.

Many people are ready for this unknown and wonderful future - even if almost everyone cant predict exactly what the future will look like.

In our imagination, 5g can upgrade the mobile Internet experience to a higher level

On December 13, 2019, China 5g economic report 2020 (hereinafter referred to as the report) was released at the China 5g economic seminar held in Beijing. The report predicts that 4G and 5g will coexist in the next decade. By 2025, Chinas 5g users will reach 816 million (1.5 billion in 2030), accounting for about 48% of mobile users; China will occupy 30% of the worlds connectivity, becoming the worlds largest 5g market.

The report points out the current situation of 5g three hot and two cold: technology hot basic communication technology research and development has always been the place that Internet giants must contend for; government hot 5g is one of Chinas future innovation strategy priorities; public opinion hot future prediction must be called 5g, accompanied by many beautiful fantasies. However, the application side in the 5g specific landing, operators in the network still maintained a calm attitude, after all, promoting 5g technology is not by imagination.

According to the report, b2b2x (business to business to third party) is one of the most noteworthy profit opportunities. Zhang Jin, a researcher at the industrial planning department of China International Economic Exchange Center, believes that the five industries of mobile terminal, pan entertainment, industrial Internet, medical health and automobile are the most promising to implement 5g applications, based on various considerations of profit-making, informatization, rigid demand and striving for industrial status.

The general affairs department of the Ministry of the interior of Japan has made a promotional video entitled connecting the world after 5g to try to depict a better picture of the future world:

Young man an is sitting on the driverless car, wearing VR glasses to watch the football match. He is excited as if he is on the spot. Then he took off his glasses and looked out of the window. He said to the car, change a song that suits the scenery.. When he got off the bus, he went to the supermarket to buy things. He used simultaneous interpretation to guide foreigners and shared the beautiful scenery with his girlfriend.

At sunset, he finally arrived at his grandparents home to summon his sister and a band who had not been able to go home in time with the hologram, and said the purpose of this trip -- he and others who were not here played for grandparents together to celebrate their hard won golden wedding anniversary. Finally, the film uses three symbols to explain the 5g understood by the Japanese: a lightning (speed), a cube (time and space) and a love sum up to get the answer of 5g - using speed to cross time and space and transmit love, it is indeed science and technology based on people.

Ericssons unleash the power of easy 5g technology commercial uses a more sci-fi form to illustrate the powerful power of edge computing and distributed cloud computing for the future world.

Among the 5g videos, most of them show driverless (not only cars, but also volodrone, the City Flying taxi and the automatic cargo plane), VR high-definition video playback and image sharing, real-time voice interaction and translation, intelligent retail, telemedicine and AR technology, as well as the new social connection and life side inspired by the mature technology Style and humanistic value. Behind the change of life style is the result of the significant improvement of network speed, bandwidth, connection quantity and stability in 5g era.

Stop talking about autonomous driving and telemedicine

5g era from simple to complex, there are many imagination: high-definition live broadcast, video and pictures will become a daily, completely farewell to low-definition Caton. Video based social applications will become more and more vigorous, and the low-definition images that are no longer compressed will be shared freely.

In the past, VR / AR applications that have been talked about rapidly and quietly have been reborn (it can be seen that the maturity of underlying technology is of great importance to the application realization), which will embody its intrinsic value in live broadcast, game, artistic creation and display, such as the chime bell of Zeng Houyi, which has only been knocked three times since its discovery; the intelligent analysis and judgment of remote diagnosis and treatment, remote operation and AI can greatly improve the viewing The efficiency and accuracy of the disease, sharing high-quality medical resources.

Intelligent manufacturing will also make efforts. Industrial equipment in the park will realize efficient networking. Data can be intelligently analyzed and reasoned in the cloud, and production processes can be reasonably arranged. Unmanned factories and assembly lines become the standard configuration.

In addition to these well-known imagination, there are some answers that are asked to stop talking about autonomous driving and telemedicine.

Countries have also launched 5g exhibitions based on cultural characteristics, such as South Korea using 5g technology to watch stars live and dance with them.

In addition, VR / AR games and cloud games are also regarded as a highlight of C-end applications.

Rahim tafazzoli, head of 5g Innovation Center at the University of Surrey, UK, said that in the 5g era of virtual reality based, augmented reality based or a mixture of the two, cloud game computing and rendering can be solved with the help of extremely high cloud computing power and transmission speed, and pushed to the end through streaming media.

In this way, the terminal itself does not need to carry out complex calculation, and the requirements of the device hardware will be greatly reduced, and the low delay feature will bring good experience to the online game. The game experience is the same as the local one, breaking the hardware limitation of low configuration terminal.

How far is all things connected?

In addition to the well-known advantages of high bandwidth, low delay and wide connection, 5g also has the characteristics of cloud network cooperation, low power consumption, and D2D (device to device) fast communication, which is more conducive to the realization of the era of everything connected.

The reason why people shout 4G changes life, 5g changes the world is that 4G has profoundly changed peoples attributes, made people easy to connect with others, found and understand everything, which is essentially a change to people; 5g will change the attributes of the world, the most intuitive is to make everything become an intelligent terminal, connect with each other, organically interact with each other, and reduce Redundancy and sharing of achievements.

But in fact, it is not easy to reach the ideal stage of interconnection of all things.

At present, the cost and computing power constraints put off this change. Although Huawei will reduce the industrial 5g module to less than 1000 yuan in October 2019, the ordinary module still needs 2300 yuan. It is reasonable to use it in more expensive electronic products such as notebook computers and mobile phones, but the cost for ordinary products is too high.

At present, many domestic enterprises are limited by the existing business model and enter the dilemma of weak innovation. Wang Yachen, general manager of Tencent wireless and IOT network, therefore believes that the mobile Internet dividend has gradually peaked and the profit model has been fixed. There are not many opportunities to be seen on the C-end, while the b-end is expected to use this wave of technological innovation to achieve new industrial upgrading by stepping up the layout.

Wu Hequan, academician of the Chinese Academy of engineering and chairman of the future mobile communication forum, published 5g empowering new life at the annual grand ceremony of 2019 science and technology billboard and said: compared with 2G, 3G and 4G, the most important change of 5g is the application from personal to industrial Internet and smart city. 5g can activate ultra-high definition video and VR / AR, and promote the development of AI + IOT to aiot, while 5g + aiot / VR / AR will be widely used in the fields of food, clothing, housing, intelligent medical care, intelligent public security, etc.

4G has brought an unprecedented era of mobile Internet. Wang Yachen believes that 5g not only serves the mobile Internet, but also empowers the industrial Internet. In the age of 5g, the driving force of cost reduction and efficiency increase in the industry is much stronger than that in the age of 4G. Edge computing and network slicing are also more suitable for the industry scenario, which can build a special industry network to ensure the stability and security of transmission.

At the same time, the fragmented application of the industry means that the large-scale replication and promotion is more difficult. It is difficult to get the C terminal application of the jitter (or trembling type). The cooperation between 5g application and network, terminal, basic software and hardware needs to be further strengthened. However, after the industry standard is gradually formulated, 5g can play the largest role in commercial and industrial.

Exchange tide and the age of science and technology

In 2020, there will be a wave of switching tide, which is dominated by manufacturers and operators, who display technology, seize the beach and cultivate user habits. 5g has given birth to base station construction, industrial adjustment, structural upgrading and habit change. These changes are inevitable for the development of technology and the times, and will eventually become a natural part of life, greatly improving peoples life and online experience.

At present, there are more than 50 cities in which 5g has been opened by three major domestic operators. It is expected that by the second half of 2020, cities above the second tier (optimistic or even third tier) in China will have sufficient 5g base stations or upgraded 4G base stations. At the same time, although the external baseband adopted by Qualcomm snapdragon 865 is highly questioned, it does not affect the mainstream Android phone manufacturers to quickly follow up and launch 5g mobile phone new products.

In addition, Huawei Hisilicon, Samsung and MediaTek have all launched 5gsoc chips. The high, medium and low-end mobile phone markets will be covered by 5g chips, not to mention the most common buy package and send mobile phone promotion method of operators.

Apple, the leader of smart device culture, is expected to launch a new machine in September 2020. If there is no accident, it will also be equipped with 5g function, with their thoughts on the future of 5g. For apple, whose ecological appeal is still strong, how to seize the opportunity of this wave of communication revolution to lead Android again will also be a bright spot in the field of science and technology in 2020.

The most fascinating part of 5g or underlying technology progress lies in its uncertainty and imagination space at the application level. It lies in that many people can explain the underlying logic of technology but cant accurately predict the application scenarios, and cant foresee the timing and mode of explosive growth. When everything is ready, it depends on who can ride the east wind and soar. Following the law of using generation, building generation, R & D generation, the industry has begun to study 6G, which is an era of virtual reality, augmented reality and mixed reality, an era of remote holographic image becoming reality, an era of truly automatic transportation and logistics, an era repeatedly depicted in science fiction films. From this perspective, the 5g era seems to be a key step in connecting the 4G pre science fiction era and the 6G true science fiction era. As Rahim tafazzoli said: what we see now is only 30% of 5g capability, and the remaining 70% will change the rules of the game. In the next decade, the answer will be gradually revealed.
