What does the advent of the 5g era mean? As the Internet continues to develop, various technologies are continuing to show an upward trend. It not only enriches everyone's spiritual life, but also effectively promotes the development of science and technology and economy. So what does the advent of the 5g era mean? What does the arrival of the 5g era mean1

The arrival of 5g means that our network will undergo earth-shaking changes. The first is the speed of the 5g network. The speed of 5g is ten times faster than the current 4G, and even It is hundreds of times faster, and by then there will be no more network delays. In addition, 5G network can not only be applied to our mobile phones, it can be applied in too many fields and is very wide. Whether it is military, industrial, or civilian, it can play a decisive role. effect.

With the advent of the 5G era, our lives may change beyond your imagination. Now I just hope that it can be quickly spread into our lives and provide more convenience.

The arrival of the 5G era means that my country’s AIOT (Artificial Intelligence Internet of Things) is about to usher in explosive development. Artificial Intelligence (AI) needs to be implemented and cannot be separated from the Internet of Things. (IOT), the Internet of Things is the goal, and artificial intelligence is 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 implementation, transmission, and control of solutions. The two complement each other. At present, many technology companies are also actively exploring ways to deeply integrate the development of artificial intelligence and the Internet of Things to promote the rapid development of the AIOT industry and seize the opportunities of the times.

Among them, Hangzhou Shizai Technology Co., Ltd.’s VAI technology uses an efficient and fast image background modeling algorithm to filter images with repeated information, and then uses a behavioral pattern recognition filtering algorithm to filter out images without important information in business scenarios. This has solved many problems for countless companies such as high store inspection costs, long management chains, and security monitoring, and has enabled companies to transition from traditional operations to intelligent operations.

What exactly is 5G?

In terms such as 3G, 4G and 5G, G is the abbreviation of the English word "generation" (x generation). 5G is the fifth generation mobile communication standard, also known as the fifth generation mobile communication technology.

As early as 2009, Huawei had already launched early research on related technologies, and in the following years demonstrated 5G prototype base stations to the outside world. Huawei announced on November 6, 2013 that it would invest US$600 million in research, development and innovation of 5G technology by 2018, and predicted that users would enjoy a 20Gbps commercial 5G mobile network in 2020.

In the field of mobile communications: the first generation is analog technology; the second generation realizes digital voice communication; the third generation is the well-known 3G technology, characterized by multimedia communication; the fourth generation is being deployed The newly developed 4G technology has greatly improved the communication speed, marking the entry into the era of wireless broadband.

5G is not a single wireless access technology (different from 4G, 3G and 2G), nor is it several brand-new wireless access technologies, but a variety of new wireless access technologies and existing wireless The general name of the solution after integration of access technology.

In fact, if you just make a phone call or send a text message, 2G is enough (even if you like to watch videos, you can download them via WiFi). So what are the advantages of 5G?

The answer is that the biggest advantage of 5G is reflected in the "Internet of Things". The Internet of Things is the Internet where things are connected. That is, through the Internet, information can be exchanged and communicated between any items.

The Internet of Things is inseparable from wireless communications with fast speed, low latency, stable signal, and low power consumption, which is 5G.

The arrival of 5G will form a unified global network. Network standards can not only solve global roaming problems, but also significantly reduce equipment and terminal costs. At the same time, it will also promote the commercialization of concepts such as driverless driving, virtual reality, and smart homes, thus entering the era of comprehensive digitalization.

So the question is, what use does 5G have for ordinary people?

What exactly can it bring us?

1. The speed is greatly improved. On the surface, 5G only has one more "G" than 4G, but in fact the gap is very big! If 4G is a two-way 8-lane highway, then 5G is at least a two-way 100-lane highway. To put it bluntly, it’s fast! Faster!

2. Panoramic video: It can also be realized on the mobile terminal. Many people will definitely be attracted by the giant screen in the stadium. But what if you could get the same real-time footage in a game or on your smartphone? You can even switch lenses and replay them instantly. The high-resolution 4K video will be refreshing to you.

3 Self-driving cars The end-to-end delay limit of the 4G network we currently use is about 50 milliseconds. It is still difficult to achieve remote real-time control. However, in the 5G era, the end-to-end delay is only It 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 the access of a small number of mobile phones. In the 5G era, 1 square kilometer There can even be 1 million network connections at the same time.

Most of them are various devices that can obtain the road environment, provide driving information, analyze real-time data, and intelligently predict road conditions... Through them, drivers can truly navigate 360 ??degrees without blind spots, regardless of the weather. It understands the status of itself and surrounding vehicles, and can provide early warning when encountering danger, and even realize driverless driving.

4 Internet robots: real-time feedback on doctor’s instructions. For doctors, robots will have great potential in surgery. But they require real-time feedback on instructions given by doctors. When executing complex commands, the working robot needs to achieve seamless "communication" with the doctor.

5 Virtual reality: Various body sensations require extremely fast network transmission. When you put on a VR helmet, you enter a virtual world where you can interact with others, play games and even high-five. With 5G, collaboration between users will usher in a new era. Two people in the same physical location will be able to cooperate with each other. Various somatosensory functions require extremely fast network transmission to enhance virtual reality. The network is inherently a pipeline. What does the advent of the 5g era mean 3

1. If 4G is "building roads", 5G is more like "building cities"

Guangzhiku: Some people think that 5G is just It's faster 4G. Is that really the case? Compared with 3G and 4G technology, what advantages does 5G technology have and what innovations does it embody?

Wang Zhiqin: 3G and 4G ushered in the era of mobile Internet. 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 communications to people-to-things and thing-to-things communications. It will be closely related to the economy. The deep integration of all fields of society has triggered profound changes in production and lifestyle.

The International Telecommunications Union has defined three major application scenarios of 5G: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (uRLLC) and massive machine type communications (mMTC).

Enhanced mobile broadband is mainly aimed at the explosive growth of mobile Internet traffic and provides mobile Internet users with a more extreme application experience; ultra-high reliability and low-latency communication is mainly aimed at industrial control, telemedicine, autonomous driving, etc. Vertical industry application requirements with extremely high requirements for extension and reliability;

The three major application scenarios of 5G will fully support the innovative development of new models and new business formats.

Compared with 4G, 5G has richer application scenarios and more diverse key performance indicators. The three most prominent performance indicators of 5G are user experience rate, air interface delay and connection density. The user experience rate of 5G 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 1/10 of 4G; the connection density can reach 1 million connections/square kilometer.

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

5G has three main features: First, stronger performance. The higher 5G speed will bring extremely low latency experience and a greater number of connections. Street lights and water meters can all be connected to the 5G network.

The second is more scenes. 5G not only considers the connection between people, but also the connection between people and things, and things and things. The third is a brand new ecology. The biggest feature of the 5G era is the deep integration of the communications industry with all walks of life. If 4G is about “building roads”, 5G is more like “building cities”. 5G will empower all walks of life by creating a cross-industry integrated ecosystem, improve the digital level of the whole society, become an important infrastructure for the smart society, and realize the vision of "5G changes society".

Qiu Xuefeng: Compared with 4G networks, 5G has made great leaps 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, together with a variety of new technologies, will become an important driving force for the development and transformation of the national economy.

For users, the first intuitive experience is the speed. In the 4G era, it takes about 5 minutes to download a 2GB high-definition movie. In the 5G era, it may only take 5 to 6 seconds to complete, which is super. High-speed network capabilities will bring new experiences to consumers and more development opportunities for new industries.

In the 2.5G era, countless possibilities will become a reality

Light Intelligence: What do you expect the 5G era to be like?

Wang Zhiqin: In the 5G era, 5G’s high bandwidth, low latency and other characteristics will further enhance the mobile Internet user experience, promote the migration of information consumption from a low-level balance of supply and demand to a high level, and help my country’s information consumption continue to grow. Expand and upgrade.

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 for accelerating technological transformation and cross-border integration of my country’s traditional industries, promoting industry, medical care, transportation, and energy. The digital, intelligent, and networked development of traditional industries such as China has improved the level of informatization, spawned new products, new models, and new business formats, and has become a strong driving force for the development of the 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 used on a large scale in education, culture, sports and other public undertakings. Provide new services such as distance education, telemedicine, and virtual reality live broadcast of sports events. For 5G to achieve real success, it must achieve deep integration 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, augmented reality education, etc.; low latency and high reliability connections can enable people to enjoy To provide convenient and high-quality services, such as telemedicine, robot nannies, virtual malls, virtual banks, etc. In March this year, China Mobile and the Chinese People's Liberation Army General Hospital completed the country's first 5G-based remote brain surgery on a human body.

5G will help comprehensively upgrade production methods. 5G will make every device in the factory perceptible, controllable, and flexibly adjustable, thereby making production unmanned, intelligent, and flexible, and greatly improving production efficiency.

For example, remote real-time production control and monitoring will significantly reduce the number of workers, reduce costs, and improve production safety; ubiquitous sensors collect a large amount of information in real time and can reduce failure rates;

< p> The connection of production information, circulation information and consumption information can meet the personalized needs of the market in a timely manner. In addition, 5G will also help to comprehensively improve the level of social governance. For example, an identity authentication system based on 5G technology and using multi-mode biometrics will improve the efficiency of government affairs; integrated air and space video collection can detect and track suspects in real time.

Qiu Xuefeng: 5G will usher in a new era, an intelligent world where everything is aware, interconnected and intelligent. In the 5G era, countless possibilities will become a reality: cars on the road in the future will be in driverless mode, and all vehicles will drive together through the network, and there will no longer be problems with traffic jams and traffic accidents; goods can be transported by drones and delivered quickly. The goods arrive at home;

Blind people can perceive the outside world through assistive devices and travel and live like normal people; personal items such as watches, glasses, toothbrushes, and infrastructure such as parking spaces and trash cans can be connected. 5G will become the entrance for everything in the world to enter the digital world.

New technologies improve the production efficiency of the entire society by increasing productivity, giving rise 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.
