The 5G frequency distribution scheme of the three major operators has been finalized recently. China Mobile has obtained 2.6GHz and 4.9GHz bands, China Unicom and China Telecom have obtained 3.5GHz bands, which means that the 5G commercial process in China has gone further.

The digital economy is in the ascendant, providing new momentum for economic restructuring and structural adjustment. Nowadays, the advent of 5G era will become an important opportunity for the next stage of Internet development. Digital economy will accelerate growth and bring important impact to the whole society.

According to Ni Guangnan, academician of Chinese Academy of Engineering, the arrival of 5G era is a new opportunity for China. "Since the era of 3G, China has gained some autonomy in technology with the help of TD_SCDMA. In the age of 4G, the technology level of TDD led by China is almost equal to that of EDD led by foreign countries. With the advent of 5G era, China's 4G is expected to be ahead in some respects. Ni Guangnan said confidently that in the new round of scientific and technological revolution, China has the hope of developing from "running after" to "running side by side" and then to "leading" in the future.

At the 20th High-tech Fair, 5G optical communication has also been widely used in many fields such as remote training, intelligent transportation, panoramic live broadcasting, medical health, environmental protection and so on.

In China Mobile booth, through 5G technology, viewers can wear VR glasses, watch 4K HD video without dead angle, watch live broadcast without Carton, and the breath of intelligent life is coming. Compared with 4G network, 5G network is characterized by low delay, high reliability and low power consumption.

Through 5G+AI technology, the high-speed and low-delay characteristics of 5G network are perfectly combined with artificial intelligence to realize the real-time judgment of hockey direction by robot goalkeepers and the quick interception of hockey to achieve the goal-keeping action, attracting many visitors to the exhibition and experiencing a winter Olympic hockey project. Through the wisdom of the network, to achieve human-computer interaction.

In fact, high-quality VR experience has very high requirements for the network environment. On the one hand, in VR/AR technology, the real-time transmission of ultra-clear picture content puts forward very high requirements for network broadband; on the other hand, speech recognition, line-of-sight tracking, gesture sensing and so on all need low-latency processing, which also puts forward higher requirements for ultra-low network latency.

In the Jupiter Industrial Internet module of China Unicom booth, we can see the future prospects of industrial production. Relevant person in charge told the High Fair that 5G network entered the factory. While reducing the cost of cables between machines, it made use of continuous coverage of high reliability network to make the mobile robot move in an unrestricted area, arrive at all locations on demand, work uninterruptedly in various scenarios and smooth switching of work content.

The enabling of 5G network can further evolve automobile driving from networked vehicle to automobile driving in real sense. China's three major operators have been positively positioned in the areas of vehicle networking, vehicle connectivity, remote information processing and other fields, and have launched a variety of applications with partners in the vertical field.

5G is not only so simple to finish a movie in seconds, but also means that the machine will be more automated, virtual reality, Internet of Things, artificial intelligence, smart city and a series of operations, with a stronger 5G, will usher in broad application space.

From every object around us to intelligent, to unmanned automobiles to free hands, to VR and AR burst out the magic of blending virtual and reality, 5G will penetrate into all aspects of our lives, let the convenience and richness of our lives soar to an unimaginable level.
