In the 5G era, high-definition movies can be downloaded in seconds

As the fifth generation of mobile communication technology, the first feeling that the 5G network brings to people is - "fast"! Open the mobile video client and download a high-definition video in just one second.

5G has many new labels: "large-scale antennas", "new coding technology", "ultra-dense networking"... 5G's "high bandwidth and high speed" are different from 4G. characteristics, making the peak speed of 5G network 20 times higher than 4G.

In the 5G era, people can smoothly watch videos with a higher resolution than the current 1080p. "The resolution in the 5G era can be increased to 4K or even 8K." Wireless and Terminal Technology of China Mobile Research Institute Deng Wei, chief researcher of the institute, used videos as examples, hoping to allow ordinary users to understand the characteristics of 5G more directly.

"Artificial Intelligence", "Virtual Reality", "Internet of Vehicles" and "Internet of Things"? These "new outlets" in the field of science and technology are changing our lives. However, the "ceiling" of 4G network technology, to some extent, makes it difficult to fully realize the potential of this type of technology.

For example, virtual reality technology, although VR and AR devices have gone through several iterations, the visual effects of most current devices are still poor. One of the reasons is related to the network environment. The high-speed and low-latency characteristics of 5G will change this status quo. CCID Consulting has predicted that after the large-scale commercialization of 5G networks, shipments of VR and AR devices will reach tens of millions of units.

“5G technology is born to serve autonomous driving.” In Deng Wei’s view, 5G’s high speed, high stability and low latency characteristics will improve the safety performance of autonomous driving. “Autonomous driving It is necessary to load high-definition maps, make rapid judgments and reactions to the surrounding environment, and remotely control vehicles, all of which have high requirements on the reliability and speed of data transmission. "The popularity of 5G networks will greatly promote wireless communication. The development of human driving application scenarios.

In addition to "unmanned driving", with the "east wind" of 5G network, after 2020, application scenarios such as "remote surgery" and "smart home" will also be closer to consumers. According to current industry analysis, global 5G application areas will mainly focus on four aspects: Internet of Vehicles, public security, smart cities, media and information entertainment. This is also what industry insiders believe is the greatest value of 5G networks.
