Mobile communications in the 5G era will change your life like this

The title of my report is "5G opens a new era of mobile communications." Mobile communication has come from the first generation to the present 5G. The entire mobile communication has been developed for ten years, each generation is 1000 times the rate of the previous generation. 1G to 4G are consumer-oriented, and 5G extends to industrial Internet and smart city applications. There are three major application scenarios: enhanced mobile broadband scenarios, low power consumption and wide coverage scenarios, and low latency and high reliability scenarios.

　　

Compared with 5G and 4G, the peak rate is increased by 30 times, the user experience rate is increased by 10 times, the spectrum efficiency is increased by 3 times, the wireless interface extension is reduced by 90%, the connection density is increased by 10 times, and the energy efficiency and traffic density are increased by 100 times. Support all aspects of mobile Internet and industrial Internet applications. In addition, 5G promotes the combination of artificial intelligence and the Internet of Things. 5G expands the capabilities of the Internet of Things. The requirement of 5G for the Internet of Things is that 1 million square meters of Internet of Things modules can be connected to the Internet, and the transmission delay is less than 10 seconds. The packet loss rate is not higher than 1%. 5G‘s low-latency broadband connection enables the Internet of Things to be directly connected to the cloud, enabling big data to be integrated with artificial intelligence decision analysis. AI+IOT becomes AIOT, that is, the development of intelligent network promotes the intelligent connection of all things. The Internet of Things used to have only IOT modules. Now, by connecting to the cloud, we have added some AI chips and some development software. Through this, we can realize many real-time decisions.

　　

　　 In addition, 5G has opened up the application of 8K video. Not only is the resolution improved, the encoding of each pixel has also been increased, and the dynamic range has been expanded. 5G high bandwidth and low latency can broadcast 8K video, and can broadcast the signals of multiple camera positions on the sports field at the same time, forming a 360-degree scene, so that the audience outside the field has the same feeling as sitting on the sports field, and can do whatever they want. See the video from every angle. Of course, the screen may be too small to watch high-definition video on the mobile phone, but the mobile phone can be linked with the smart screen. The high-definition video is not only used for entertainment, but also for telemedicine, and can also be used to troubleshoot machine faults on the remote production line. One industry, the industry of live video broadcasting can reach 70 billion US dollars in 2021, of which 60% of the world‘s Internet users watch live video in China.

　　

In addition, in the past, more advanced equipment was required to play games. The threshold for downloading the game is still relatively high. Now 5G terminals can be directly connected to the cloud, and the game does not need to be directly downloaded to the terminal. The equipment for playing games can be greatly simplify. Popularizing games is not our goal. Using this technology can also be used for collaborative work and digital cultural creative industries. Now virtual reality and augmented reality have been developed, but it is difficult to get applied without 5G. It turns out that it requires a bandwidth of 1 G and a delay of less than 7 milliseconds, which is difficult to achieve in the 4G era Now, 5G is possible. 5G plus VR is not only used for games, but also supports collaborative work. 5G+VR can be used for distance education, so that children in remote areas can also receive high-quality education resources in big cities. The problem of insufficient experimental methods in remote areas can be solved through online virtual experiments, and it can be used well for training. The Palace Museum can now make visitors feel very good with VR helmets.

　　

　　 5G has greater applications, including power grids, ports, oil refineries, construction companies, metallurgical companies, mechanical processing companies, and chemical companies. COMAC is a big aircraft. It has built the world‘s first 5G+ industrial Internet park. The aircraft is made of composite materials. The composite materials are on the wings and fuselage of the aircraft. In the past, it was to be shut down for inspection. Now with 5G The high-definition video camera can directly transfer the situation to the background in real time, and compare it with the existing pictures of big data and artificial intelligence. This greatly improves the work quality and efficiency. The aircraft is assembled section by section, each section There are cables in it. In the past, they were very carefully connected by drawings. Now 5G+VR helmets can let workers know which cable to connect, which not only improves efficiency, but also improves the quality of work.

　　

More applications are machine vision. In China, there are currently 3.5 million workers who rely on visual inspection of product quality on the production line every day. Although these workers are very serious, they still cannot avoid mistakes. Using industrial high-definition video and 5G, direct and The combination of artificial intelligence in the background can well find quality problems, and the efficiency is far higher than that of workers. Huaxing Optoelectronics cooperated with Tencent to check the LCD panel. Qingdao Port has realized the remote lifting of containers, which has greatly improved the efficiency and efficiency. 5G has more applications, or better adapts to the needs of Internet of Vehicles. In the past, the response time in the 4G era was 100 milliseconds, and 5G+ edge computing was only 1 millisecond. It turned out that we used radar and other sensing methods to realize the perception of environmental conditions. However, vehicle-to-vehicle, vehicle-to-cloud, and vehicle-to-parking connection cannot be achieved. The high reliability and low latency of 5G can fully support this application. In fact, the Internet of Vehicles not only improves transportation efficiency, but also reduces many traffic safety accidents. It is an industry in itself. IoV software, including automotive electronics, and IoV services, will reach a global scale of US$1.5 trillion by 2030, far exceeding the total size of the automotive industry.
