What does the advent of the 5G era mean? With the continuous development of the Internet, various technologies are constantly showing an upward trend. 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? 1

The arrival of 5g means that our network will undergo earth-shaking changes. First of all, the speed of 5g network is ten times or even hundreds times faster than the current 4G, and then there will be no network delay. In addition, the 5G network can not only be applied to our mobile phones, but also can be applied in 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 beyond your imagination. Now I just hope that I can quickly spread to our lives and provide more convenience.

The arrival of the 5G era indicates that AIOT (Artificial Intelligence Internet of Things) is about to usher in explosive development in China. Artificial intelligence (AI) needs to land and cannot be separated from the Internet of Things (IOT), which is the goal and the way to realize it.

artificial intelligence calculates, processes, analyzes and plans problems, while the internet of things focuses on the landing, transmission and control of solutions, and the two 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 Hangzhou Vision Technology Co., Ltd. uses efficient and fast image background modeling algorithm to filter 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 shop patrol cost, long management chain, security monitoring and so on for countless enterprises, and realized the transition from traditional operation to intelligent operation. What does the advent of the 5g era mean? 2 < P > What is 5G?

among nouns such as 3G, 4G and 5G, g is the abbreviation of the English word "generation" (generation x). 5G, the fifth generation mobile phone mobile communication standard, is also called the fifth generation mobile communication technology.

as early as 29, Huawei had already started the early research on related technologies, and in the following years, it showed the 5G prototype base station to the outside world. On November 6th, 213, Huawei announced that it would invest 6 million dollars in research and innovation of 5G technology before 218, and predicted that users would enjoy a commercial 5G mobile network with 2Gbps in 22.

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, characterized by multimedia communication. The fourth generation is the spreading 4g technology, and its communication rate is greatly improved, marking the entry into the era of wireless broadband.

5G is not a single wireless access technology (different from 4G, 3G and 2G), nor are it several brand-new wireless access technologies, but a general term for 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 will be enough (even if you like watching videos, you can download them by WiFi), so what are the advantages of 5G?

the answer is that the biggest advantage of 5G lies in the "internet of things", which is the internet connected with things, that is, through the internet, information exchange and communication can be carried out between any objects.

the internet of things can't be separated from wireless communication with high speed, low delay, stable signal and low power consumption, 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 comes. 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 one more "G" than 4G, 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 1-lane expressway. To put it bluntly, it is fast! Faster!

2. full-motion video: The mobile terminal can also realize that many people will be attracted to the giant screen in 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. The high-resolution 4K video will make you feel refreshed.

3 The end-to-end delay of the 4G network we are currently using for self-driving cars is about 5 milliseconds, and it is still difficult to realize remote real-time control. However, in the 5G era, the end-to-end delay only takes 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 to connect to the network at the same time. It only supports a small number of mobile phone access. In the 5G era, there can even be 1 million network connections within 1 square kilometer at the same time.

most of them are all kinds of devices, which can know the road environment, provide driving information, analyze real-time data and intelligently predict the road conditions ... Through them, drivers can truly know the situation of themselves and the surrounding vehicles 36 degrees without being affected by the weather, and they can also give early warning in case of danger, or even realize unmanned driving.

4 Internet robot: Feedback doctors' instructions in real time. For doctors, robots will be promising in surgery. But they need to give real-time feedback to the instructions issued by doctors. When executing complex commands, the working robot needs to communicate seamlessly with the doctor.

5 Virtual reality: All kinds of somatosensory sensations need to be transmitted through the Internet at a high speed. 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 a pipeline by nature. 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? Compared with 3G and 4G technologies, what are the advantages and innovations of 5G technology?

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 people-to-people communication to people-to-people communication and things-to-things communication, 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 such as industrial control, telemedicine and automatic driving, which have extremely high requirements on delay and reliability.

Mass machine communication is mainly aimed at smart cities, smart homes, environmental monitoring and other application requirements aiming at 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 1Mbps to 1Gbps, which is more than 1 times that of 4G; The air interface delay is as low as 1ms, which is 1/1 of 4G; The connection density can reach 1 million connections/km2.

Huang yuhong: 5G is not a sudden change or sudden change of a certain technology, but an innovative integration of a series of new technologies. If 5G is compared to a pearl necklace, each pearl is an innovative technology. 5G not only inherits the mature technology of 4G, but also introduces a lot of technological innovations to break through bottlenecks and problems that cannot be solved by existing networks.

5G has three main characteristics: first, it has stronger performance. The higher rate of 5G will bring extremely low delay experience and more connections, and street lamps and water meters can access the 5G network.

second, more 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 will empower all walks of life, enhance the digital level of the whole society, become an important infrastructure of a smart society, and realize the vision of "5G changing society".

Qiu Xuefeng: Compared with 4G network, 5G has made great strides 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 experience is speed. It takes about 5 minutes to download a 2GB HD movie in the 4G era, and it may take only 5 to 6 seconds to complete it in the 5G era. The ultra-high-speed network capability will bring new experiences to consumers and more development opportunities to new industries.

In the 2.5G era, countless possibilities will come true

Bright Think Tank: What do you expect in the .5G era?

Wang Zhiqin: In the 5G era, the high bandwidth and low latency of 5G will further enhance the user experience of mobile Internet, promote the information consumption from a low level of supply and demand balance to a high level of migration, and help China's information consumption continue to expand and upgrade.

At the same time, the combination of 5G with cloud computing, big data, artificial intelligence and other new generation information technologies will become an incubator for accelerating technological transformation and cross-border integration of traditional industries in China, promoting the digitalization, intelligence and networking development of traditional industries such as industry, medical care, transportation and energy, improving the level of informatization, giving birth to new products, new models and new formats, and becoming 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 precise social governance; 5G can be widely used in education, culture, sports and other public undertakings, 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 Chinese People's Liberation Army completed the first remote brain surgery based on 5G in China.

5G will help upgrade the production mode in an all-round way. 5G will make every equipment in the factory perceivable, 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 demand of the market in time. In addition, 5G will also help improve the overall level of social governance. For example, an identity authentication system based on 5G technology and adopting multimodal biometrics 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 usher in a new era, an intelligent world where everything is perceived, interconnected and intelligent. In the 5G era, countless possibilities will become a reality: 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 problems of traffic jams and traffic accidents; Goods can be transported by drones and delivered to home quickly;

Blind people can perceive the outside world through auxiliary devices and travel and live like normal people; Personal items such as watches, glasses, toothbrushes, and infrastructure such as parking spaces and garbage bins can all be connected into one. 5G will become the entrance for everything in the world to enter the digital world.

new technologies 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 major opportunity, and the Internet of Everything will promote the emergence of a new trillion-dollar market.
