What does the advent of the 5g era mean? With the continuous development of the Internet, various technologies are also on the rise. Not only enriched everyone's spiritual life, but also effectively promoted the development of science and technology and economy. So what does the advent of the 5g era mean?
What does the advent of the 5g era mean? The arrival of 1 5g represents the earth-shaking changes in our network. First of all, the speed of 5g network is ten times or even hundreds times faster than the current 4G, and there will be no network delay. In addition, the 5G network can be applied not only to our mobile phones, but also to many fields, which can play a decisive role in military, industrial and civil affairs.
With the advent of the 5g era, the possible changes in our lives are unimaginable. Now I only hope that it can be quickly popularized in our lives and provide more convenience.
The arrival of the 5G era indicates that China's AIOT (Artificial Intelligence Internet of Things) is about to usher in explosive development. Artificial intelligence (AI) needs to land without the Internet of Things (IOT), which is the goal and the way to achieve it. The realization of the Internet of Things is inseparable from the development of artificial intelligence.
Artificial intelligence calculates, processes, analyzes and plans problems, while the Internet of Things focuses on the landing, transmission and control of solutions, which complement each other. At present, many technology companies are also actively exploring the path of deep integration of artificial intelligence and the development of the Internet of Things, promoting the rapid development of the AIOT industry and seizing the opportunities of the times.
Among them, the VAI technology of Hangshi Technology Co., Ltd. uses efficient and fast image background modeling algorithm to filter out images with repeated information, and then uses behavior pattern recognition filtering algorithm to filter out images without important information in commercial scenes. This has solved many problems such as high cost of shop inspection, long management chain and safety monitoring for countless enterprises, and realized the transformation from traditional operation to intelligent operation.
What does the advent of the 5g era mean? What exactly is 2 5G?
Among the nouns such as 3G, 4G and 5G, G is the abbreviation of the English word "Generation X". 5G, the fifth generation mobile phone communication standard, is also called the fifth generation mobile communication technology.
As early as 2009, Huawei had already started the preliminary research on related technologies, and demonstrated the 5G prototype base station to the outside world in the following years. 20 13,16543816 October, Huawei announced that it would invest 600 million dollars in the research and development and innovation of 5G technology before 20 18, and predicted that users would enjoy a commercial 5G mobile network with 20Gbps in 2020.
In the field of mobile communication: the first generation is analog technology; The second generation realized digital voice communication; The third generation is a well-known 3g technology, which is characterized by multimedia communication. The fourth generation is the popularization of 4g technology, and the communication rate has greatly increased, marking the entry into the era of wireless broadband.
5G is not a single wireless access technology (different from 4G, 3G, and 2G), nor several new wireless access technologies, but the general name of solutions after the integration of many new wireless access technologies and existing wireless access technologies.
In fact, if you just make a phone call and send a text message, 2G is enough (even if you like to watch videos, you will download it by WiFi), so what are the advantages of 5G?
The answer is that the biggest advantage of 5G lies in the "Internet of Things", that is, the Internet connected with things, that is, through the Internet, information can be exchanged and communicated between any items.
The Internet of Things is inseparable from high-speed, low-delay, stable signal and low-power wireless communication, that is, 5G.
The arrival of 5G will form a global unified network standard, which will not only solve the global roaming problem, but also greatly reduce the cost of equipment and terminals. At the same time, it will also promote the commercialization of concepts such as driverless, virtual reality and smart home, thus entering the era of comprehensive digitalization.
Then the question is coming, what is the use of 5G for ordinary people?
What can it bring us?
1. The speed is greatly improved. On the surface, 5G is only more than 4G1"g", but in fact, the gap is very large! If 4G is a two-way eight-lane expressway, then 5G is at least a two-way 100 lane expressway. To put it bluntly, it is quick! Hurry up!
2. Full-motion video: The mobile terminal can also realize that many people will be attracted by the giant screen of the gymnasium. But what if you can get the same real-time images in games or smartphones? You can even switch shots and replay them instantly. High-resolution 4K video will refresh you.
3 Self-driving cars The end-to-end delay of the 4G network we are currently using is about 50 milliseconds, and it is still difficult to achieve remote real-time control. In the 5G era, the end-to-end delay only needs 1 millisecond, which is enough to meet the requirements of intelligent transportation and even driverless driving; The current 4G network does not support such a large number of devices connecting to the network at the same time, and only supports a small number of mobile phones. In the 5G era, 1 square kilometer can even have 1 10,000 network connections at the same time.
Most of them are all kinds of devices, which can learn the road environment, provide driving information, analyze real-time data, and intelligently predict road conditions ... Through them, drivers can truly understand themselves and the surrounding vehicles 360 degrees without being affected by the weather, and can also give early warning when encountering danger, and even realize unmanned driving.
4 Internet robot: real-time feedback of doctors' instructions For doctors, robots have great potential in surgery. But they need real-time feedback on the instructions given by doctors. When executing complex commands, the working robot needs to communicate seamlessly with the doctor.
5 Virtual Reality: All kinds of somatosensory feelings need fast network transmission. When you wear a VR helmet, you enter a virtual world, where you can interact with others, play games and even high-five. With 5G, the collaboration between users will usher in a new era. Two people in the same physical location will be able to cooperate with each other. All kinds of somatosensory functions need extremely fast network transmission to strengthen virtual reality, and the network is essentially a pipeline.
What does the advent of the 5g era mean? 3 1. If 4G is "building roads", 5G is more like "building cities".
Bright Think Tank: Some people think that 5G is just a faster 4G. Is that really the case? What are the advantages and innovations of 5G technology compared with 3G and 4G technologies?
Wang Zhiqin: 3G and 4G have opened the era of mobile Internet, and 5G has expanded from the mobile Internet to the field of mobile Internet of Things, and its service objects have expanded from communication between people to communication between people and things, which will be deeply integrated with various fields of economy and society and lead to profound changes in production and lifestyle.
The International Telecommunication Union has defined three application scenarios of 5G: Enhanced Mobile Broadband (eMBB), Ultra-high Reliability and Low Delay Communication (uRLLC) and Mass Machine Communication (mMTC).
Enhancing mobile broadband is mainly aimed at the explosive growth of mobile Internet traffic, providing a more extreme application experience for mobile Internet users; Ultra-high-reliability and low-delay communication is mainly aimed at vertical industry applications that require high delay and reliability, such as industrial control, telemedicine and autonomous driving.
Mass machine communication is mainly aimed at smart city, smart home, environmental monitoring and other application requirements for sensing and data acquisition. The three application scenarios of 5G will fully support the innovative development of new models and new formats.
Compared with 4G, 5G has richer application scenarios and more diversified key performance indicators. The three most prominent performance indicators of 5G are user experience rate, air interface delay and connection density. The experience rate of 5G users can reach 100Mbps to 1Gbps, which is more than 10 times that of 4G; The air interface delay is as low as 1ms, which is 4G110. The connection density can reach 6.5438+0 million connections /km2.
Huang Yuhong: 5G is not a sudden advance or mutation of a certain technology, but an innovative integration of a series of new technologies. If 5G is compared to a pearl necklace, every pearl is an innovative technology. 5G not only inherits the mature technology of 4G, but also introduces a large number of technological innovations, breaking through bottlenecks and problems that cannot be solved by existing networks.
5G has three main characteristics: First, it has stronger performance. The higher speed of 5G will bring a very low latency experience and more connections, and both street lamps and water meters can access the 5G network.
Second, there are many scenes. 5G considers not only the connection between people, but also the connection between people and things, things and things. The third is a brand-new ecology. The biggest feature of the 5G era is the deep integration of the communication industry and all walks of life. If 4G is "building roads", 5G is more like "building cities". By creating a cross-industry integrated ecology, 5G empowers all walks of life, enhances the digital level of the whole society, becomes an important infrastructure of a smart society, and realizes the vision of "5G changing society".
Qiu Xuefeng: Compared with 4G network, 5G has made great progress in data transmission speed, access capacity and data transmission delay. 5G is not only an upgrade of wireless communication technology, but also a major technological change. From driverless cars to smart cities, from virtual reality to modern factories, 5G will become an important driving force for the development and transformation of the national economy together with a variety of new technologies.
For users, the first intuitive feeling is speed. It takes about 5 minutes to download a 2GB HD movie in the 4G era, and it may only take 5 to 6 seconds in the 5G era. Ultra-high-speed network capabilities will bring new experiences to consumers and more development opportunities to new industries.
In the 2.5G era, countless possibilities will become a reality.
Bright Think Tank: What are your expectations for the .5G era?
Wang Zhiqin: In the 5G era, the high bandwidth and low latency of 5G will further enhance the user experience of the mobile Internet, promote the migration of information consumption from a low level of supply and demand balance to a high level, and help China continue to expand and upgrade its information consumption.
At the same time, the combination of 5G with new generation information technologies such as cloud computing, big data and artificial intelligence will become an incubator to accelerate the technological transformation and cross-border integration of traditional industries in China, promote the digitalization, intelligence and networking development of traditional industries such as industry, medical care, transportation and energy, improve the level of informatization, and give birth to new products, new models and new formats, which will become a strong driving force for the development of digital economy.
For example, the combination of 5G with e-government and smart city construction will promote scientific government decision-making and accurate social governance; 5G can be widely used in education, culture, sports and other public utilities, providing new services such as distance education, telemedicine and live broadcast of virtual reality sports events. To achieve real success, 5G must be deeply integrated with all walks of life and become a key information infrastructure for economic and social development.
Huang Yuhong: In the 5G era, ultra-high bandwidth will bring people immersive new experiences, such as 4K video and augmented reality education. Low-latency and high-reliability connection can make people enjoy convenient and high-quality services, such as telemedicine, robot nanny, virtual shopping mall, virtual bank and so on. In March this year, China Mobile and the General Hospital of the Chinese People's Liberation Army completed the first remote brain surgery based on 5G in China.
5G will contribute to the overall upgrading of production methods. 5G will make every device in the factory sensible, controllable and flexible, thus bringing unmanned, intelligent and flexible production and greatly improving production efficiency.
For example, remote real-time production control and monitoring will greatly reduce the number of workers, reduce costs and improve production safety; Ubiquitous sensors collect a lot of information in real time, which can reduce the failure rate;
The docking of production information, circulation information and consumption information can meet the personalized needs of the market in time. In addition, 5G will also help to improve the overall level of social governance. For example, an identity authentication system based on 5G technology and multi-modal biometric identification will improve the efficiency of government affairs; Video capture integrated with air and space can find and track suspects in real time.
Qiu Xuefeng: 5G will open a new era, a smart world with all things perceived, all things interconnected and all things interconnected. In the 5G era, countless possibilities will come true: in the future, cars on the road will be unmanned, and all vehicles will drive together through the network, and there will be no more traffic jams and traffic accidents; Goods can be transported by drones and sent home quickly;
Blind people can perceive the outside world through auxiliary equipment and travel and live like normal people; Personal items such as watches, glasses and toothbrushes, as well as infrastructure such as parking spaces and garbage cans, can all be connected into one. 5G will become the entrance for everything in the world to enter the digital world.
New technology can improve the production efficiency of the whole society by improving productivity, and give birth to new industrial space and value. For many industries, 5G will be a great opportunity, and the Internet of Everything will promote the emergence of a new trillion-dollar market.
