What is 5G? What can 5G do? What will 5G bring in the future?

The first impression given by the promotion of 5G is that the network speed is fast, which is also the easiest to understand. In fact, the true meaning of 5G is not the case.

Let's talk about the current 4G, which refers to the fourth generation mobile communication technology. The transmission rate can reach 20Mbps, even as high as 100 Mbps. The downlink speed of 4G mobile phone system is 100mbps, and the uplink speed is 30mbps. In order to make the transmission of 4G communication reach 100Mbps, communication operators must carry out substantial transformation and research on the basis of 3G communication network, which is the definition of 4G and theoretical data transmission. Up to now, some places have also opened up to 300Mbps after transforming infrastructure. But in most areas, mobile phones only have 20-30Mbps, not 300Mbps. Because of the network structure, you can only watch 4K videos. In some places abroad, 4G, 300-400Mbps have been realized, which can meet the existing use and even watch 8K video.

To sum up, our 4G is not doing very well. At present, the average transmission rate of the fourth generation Long Term Evolution (4G LTE) service is only 75Mbps, but it has met our normal use. Back to 5G, as the name implies, refers to the fifth generation mobile communication technology, with a transmission rate of 1 Gbps and a maximum of 5Gbps. In the future, the transmission rate of 5G network will reach 10 Gbps. Seeing these data, 5G is indeed nearly 50 times faster than the previous generation 4G, and the peak value is almost 100 times.

What I said above is actually that the network speed has become faster, which is what most people need and expect. But the real content of 5G is not this. The current 4G network has been able to meet the needs of many people.

So what is the change that 5G has brought me? 5G is not only the improvement of network speed, but also the expansion of the application range of wireless communication technology. It is not only used in mobile phones, tablet computers and other devices, but also widely used in smart cities, smart homes, drones, augmented reality, virtual reality, Internet of Things and so on, which will bring more convenience and fun to people's lives.

This problem is very broad, just as people are confused in the face of the 4G era, the changes brought by 5G are difficult to predict. At that time, from 3G to 4G, people just thought it was faster to watch movies, and the APP could be downloaded in seconds. But what I didn't expect was that 4G brought mobile payment, and a radical change was almost everyone's living habits. What can 5G bring to life? It's hard to predict, but what can 5G bring to the game industry? Is it true that instant combat is no longer stuck, and the king's pesticides are not dropped? That's not enough! Cloud game!

Cloud game is a game mode based on cloud computing. In the running mode of cloud games, all games run on the server, and the rendered game images are compressed and transmitted to users through the network. On the client side, the user's game device does not need any high-end processor and graphics card, but only the basic video decompression ability. Cloud computing is a computing method based on the Internet, in which the software and hardware resources and information enjoyed by * * * can be provided to computers and other devices as needed. A network that provides resources is called a "cloud".

Put a lot of operations in the cloud, and then send back the operation results through 5G high speed, so that the configuration of mobile phones and PCs can be greatly reduced, or the cloud and handheld devices are highly matched to obtain the ultimate audio-visual experience.

And this technology has been developed by major manufacturers as early as a few years ago, but 5G makes it all come faster.

NVIDIA

As early as 20 13, the grid server of NVIDIA Shield Cloud Game was launched.

OPPO

At MWC 20 19, OPPO and Qualcomm demonstrated the 5G cloud game on the booth.

Microsoft

20 18 10 Microsoft officially announced the cloud game service: the mobile phone can play 3A masterpieces with only 4G network.

Tencent

2065438+March 2009 Tencent Cloud game platform "START" began to make an appointment for internal testing, only in Guangdong and Shanghai.

The era of 5G cloud games is coming, which is the change of 5G to the game that I can see at present.

I'm glad to answer your question. In fact, the difference between 5G and 4G is really great. Let me talk about the SMS function, which almost replaced WeChat and Alipay.

I brushed a message on Tik Tok today, which made me feel very shocked.

It goes like this:

Wechat is used for payment, QQ is used for storing photos, Tik Tok is used for staying up late, telephone is used for receiving express delivery, and SMS is used for receiving verification code. You can enjoy your product, but you can enjoy your product.

First, the decline of SMS.

I don't know how you feel when you see this statement. To tell you the truth, my feelings quite agree with these views, because what it summarizes is too consistent with my usual habits. At the same time, I am also confused. What about China Mobile, China Telecom and China Unicom? Decline? SMS, in particular, has actually been reduced to the role of just receiving verification codes.

In fact, as we all know, in the past, besides QQ, phone calls and text messages were our main social ways. Because of this, there is a saying that couples talk on the phone, and the MMS function of SMS is also deeply loved by the public. But unconsciously, the social function of WeChat gradually replaced telephone calls and text messages, so that telephone calls and text messages almost declined.

Second, 5G SMS has been transformed.

At the same time, I read another report. On the morning of April 8th, China's three major operators (China Mobile, China Unicom and China Telecom) jointly released a white paper on 5G messages. According to the report in the white paper, this kind of 5G SMS is a direct makeover, which is not much different from 4G SMS. I wonder, will mobile phones and text messages be completely transformed because of the launch of 5G? Will it no longer just accept express delivery and verification code?

I continued to look down, only to know that the 5G SMS launched this time has the trend of challenging Alipay and WeChat. Why do you say that? Let's take a look at the new features launched this time. It is said that the white paper introduces that this 5G SMS has been completely transformed on the basis of the previous 4G, mainly in the following aspects:

(1) SMS can send messages in various formats.

First of all, the short message function is no longer limited to sending text, because as we all know, in the past, mobile phone short messages were almost all text, and it was very troublesome to send MMS if you wanted to send pictures. But now, 5G can not only send text, but also send pictures, voices, locations and even videos. It has almost the social function with WeChat directly, and there is no need to reinstall a software like WeChat.

(2) SMS is distributed through two channels.

Seeing this, you may think that WeChat can establish groups, such as the work groups of family members, friends and company colleagues. 5G SMS, is this okay?

Yes, the three major operators, China Mobile, China Unicom and China Telecom, are really United as one. This time, 5G SMS is divided into two interactive modes, namely person-to-person and business-to-person. I believe everyone will understand when they see this. The so-called person-to-person chat is just like chatting between friends on WeChat, while business-to-person chat is a group chat management mode, which means that whether it is telecom, mobile or China Unicom, a group chat mode can be established.

(3) SMS booking and payment methods

This is another new problem. Everyone knows that WeChat and Alipay have one thing, that is, payment, and online booking of air tickets and train tickets. So this time, 5G can be considered prepared, and it is also affordable to book these directly on the mobile phone.

(4) SMS encryption service

In addition, this 5G SMS also introduced intimate functions that Alipay and WeChat don't have, that is, supporting interactive modes such as encrypted transmission and graphical password, which means that you can add a password to your SMS alone, which others can't see. You can choose the encryption mode for chatting with others, which protects your privacy.

Third, the 5G era affected by the epidemic.

To be honest, I don't know how you feel when you see this. Anyway, it gives me the feeling that WeChat Alipay may have a new opponent, but let me transfer from WeChat chat to mobile phone. I think it still needs an adaptation process.

In fact, when it comes to 5G, everyone is familiar with it, because for 5G, everyone has never seen it and heard of it. As early as 20 19, the promotion of 5G was already in place, so that many friends who originally planned to change their mobile phones thought that I would not change it first, and it was not too late to wait until the 5G mobile phone came out.

But no one expected that a sudden epidemic broke all the arrangements. For those who originally planned to buy a mobile phone, they could only spend money on the necessities of life, while for the R&D company of 5G, they could only postpone the launch of 5G, but fortunately, everyone finally waited until the ice and snow melted and the epidemic was controlled, so everything began to recover. So now that 5G is online, will you choose to use it?

Fourth, the 5G charging model.

I think in addition to the function of 5G SMS, we also care about a problem, that is, the charge of 5G SMS is too expensive, and a message 1 dime, let's forget it.

However, the three major operators have long thought of this problem, that is, 5G messages will change the previous billing model, no longer charging directly according to articles, but charging according to traffic, and the charging standard may be more affordable than WeChat. How's it going? Heartbeat?

Being in the artificial intelligence industry, I know that 5G is the foundation and hope of the industry in the future 10.

The rapid development of mobile Internet and Internet of Things gave birth to the simple comparison of the fifth generation mobile communication technology (5G). The application of 1G is telephone voice, 2G develops to SMS, 3G is a typical application of pictures, and 4G is now video, so the typical applications of 5G are artificial intelligence and internet of things, such as car networking+autonomous driving, AR/VR, 4K/8K ultra-high definition video and so on.

From 4G to 5G: performance and experience improved 10-100 times. Peak rate increases from 1G bps to 10G or even 20G bps, experience rate increases from 10M to 0. 1- 1G, and time delay increases from10ms. The number of connections has increased from 6,543,800+terminals per square kilometer to 6,543,800+terminals, and these basic performances have increased by 654.38+ 000 times, reflecting the advantages of 5G: large bandwidth, high reliability, low delay and large connection.

5G applications will subvert the way of life and production 5G+ culture and entertainment: 4K/8K, and VR technology will be popularized. The current 4G can't meet this application. For example, 4K HD content is rare, and the resolution and delay of VR are unacceptable. After 5G, you will be able to experience: 4K/8K ultra-HD live broadcast, ultra-HD cloud games (that is, point-and-play without downloading), VR live broadcast, VR cloud games and so on.

5G+ smart transportation: autonomous driving into life. With the characteristics of low delay and high reliability, 5G can realize real-time communication between vehicles, people and roads, form a complete intelligent transportation system, and provide a reliable environment for all kinds of driverless cars. You will be able to take a driverless bus, see a driverless freight logistics vehicle and even drive a special engineering vehicle automatically.

5G+ smart medical care: telemedicine will be realized. Through the 5G network, doctors can perform remote surgery and remote diagnosis in different places. China has achieved the world's first remote surgery in the 5G environment, which will become a popular way to solve the imbalance of medical resources in the future.

5G+ Smart Home: Once imagined future life becomes a reality. At present, smart home is limited by network bandwidth, and there are often problems such as stuck, poor connection, poor user experience, and many robot products are unreliable. The arrival of 5G will make all the furniture and electrical appliances in your home intelligent, remotely monitor every corner of your home, and control the lighting, doors and windows, security, home appliances and other equipment in your home in real time with mobile phones, so that robots can become a part of your family in different forms.

5G+ Industry: Make industrial production more efficient and safer. For example, 5G+AR can monitor the defects of industrial equipment, guide maintenance, and reduce the difficulty and danger of workers' operation; The equipment in the production workshop is remotely controlled through the 5G network, and the production workshop is completely controlled by AGV and robot; There is also a 5G HD camera, which can collect and monitor all the production data and production situation of the factory.

As the communication foundation, 5G will be combined with artificial intelligence, sensing technology, big data cloud computing and other technologies to bring subversive innovation to all walks of life. It can be predicted that these ideas will be realized one by one in the next 5- 10 years.

The so-called 5G, the fifth generation communication technology, is an evolved version of 4G.

With the 5G signal, ordinary people can watch ultra-high-definition videos online, download the app without waiting, and wear VR glasses without dizziness, which is not too much surprise for us. After all, how many people have installed a full set of smart home appliances at home and need to link with 5G signals?

However, 5G technology is particularly important for the digital transformation of modern industries. Imagine if a new clothing brand wants to establish a full chain business model from clothing processing to online and offline sales. How amazing is the amount of data? Only the high bandwidth of 5G technology can ensure the accurate interaction of data. At the same time, the traditional manufacturing industry wants to take it to the next level in the assembly line, which is inseparable from the low-latency 5G technology.

From birth to application, the most direct feature that a new technology can bring to our society is to improve our life. Whether it is the above-mentioned faster network speed or supporting the digital transformation of the industry, its essence is to make the social division of labor more efficient, so that more people can release their productivity and return to what they love.

The steam engine is like this, electricity is like this, the Internet is like this, and so is 5G.

As a former Huawei wireless engineer, I have exchanged 5G topics with others in Huawei countless times.

For the public outside the communication industry, we can understand it this way: faster network, lower delay and more connections.

There are three main aspects of future 5G applications:

For applications based on VR and cloud games, people who play mobile games with high requirements on network speed and delay should have a deep understanding. How important is the network speed when playing games outdoors! With the popularization of edge cloud computing, applications, cloud computing and 5G will meet people's higher and higher network experience.

Autopilot, which requires extremely high delay, has a revolutionary impact on traffic and network. It needs communication networks between road facilities and cars and between cars. Because the car may be driving at high speed, it needs real-time synchronization, and the delay requirement is particularly high.

At present, under the impetus of "new infrastructure" of China municipal government, many places have put forward the pilot project of 5G vehicle-road coordination, which will further promote 5G construction.

Industry Internet is used in many industries, such as medical care, education and industry. There is a demand for the network: massive terminal connections, real-time data transmission and lower delay. For example, the drone inspection in the power industry is a good example. Unmanned aerial vehicle (UAV) replaces people for power inspection, remote real-time control and real-time viewing of video streams, which are all requirements for the network.

Yes, it sounds very tall. Ordinary people really don't know what 5G can do.

In June 2020, the first anniversary of the official commercialization of 5G in China. In the past year, 5G technology has been given high hopes, and the pace of commercialization is also advancing rapidly. The data shows that there are currently more than 36 million domestic 5G users, more than 250,000 5G base stations have been built, and the cumulative domestic shipments of 5G mobile phones at the terminal level have reached 59.85 million. 5G is getting closer and closer to our lives, which has also given birth to people's discussion on new industrial opportunities in the 5G era.

Based on the advantages of 5G technology in high speed, low delay and large link level, people have given unprecedented expectations to 5G, which is also considered as a leap in the new era. The convening of the two sessions, the horn of the new infrastructure sounded, and 5G, as the forerunner of the new infrastructure, also pressed the acceleration button.

In the White Paper on Top Ten Application Scenarios in the 5G Era recently released by Huawei, 5G applications are mainly divided into ten fields, such as VR/AR, car networking, wireless robot cloud control, smart energy, wireless medical, wireless home entertainment, networked drones, social networks, personal AI assistance, and smart cities.

Alibaba Dharma Institute listed the following areas around the application scenarios of 5G technology:

Around the scenes of high-speed download, ultra-high-definition video, cloud office, cloud game, VR/AR with higher rate (eMBB);

Industrial automation, autonomous driving, mobile medical care and other scenarios around ultra-high reliability and low delay (uRLLC);

Scenes such as the Internet of Things, smart cities, intelligent transportation, and smart homes around mass machine communication (mMTC).

From the application trend, the technical advantages of 5G are mainly reflected in: visual sharpening, extreme experience, cloud integration and on-site enhancement.

Visual sharpening: 5G+ Ultra HD 4K/8K video;

Experience the ultimate: 5G+VR/AR+ cloud game

Cloud integration: 5G pushes the terminal to always connect with the cloud.

On-site improvement: 5G+AIoT+AR improves on-site operation efficiency.

In terms of industrial applications, smart factories in the field of industrial internet, smart grids in the power industry, car networking in the automobile industry, intelligent security, telemedicine and distance education are all promising industrial applications.

As a high-profile next-generation mobile communication network, the global testing, layout, construction and application layout of 5G are heating up, and related industries are also actively trying. Although the speed of 5G has been improved by leaps and bounds, it is incomparable to the previous generation wireless communication technology in terms of capacity, delay, security and user experience, but the process of industrial scale landing and business closed loop is relatively slow, and 5G carries too many missions and expectations.

For the country, the "new infrastructure" represented by 5G has not only become a "catalyst" for a new round of development, but also the core of soft power and competitiveness. Cutting-edge technologies such as 5G, cloud computing, big data and artificial intelligence must also be powerful engines for future global economic development.

Thank you for your invitation. My understanding of this problem is:

For ordinary users, the popularity of 5G mainly depends on the coverage area of signal towers, the popularity of supporting industries, and the promotion of smart terminals and Internet of Things manufacturers.

Let's take a look at the popularity of signals:

According to the data of the Ministry of Industry and Information Technology, before the Spring Festival, there were 5G base stations175,000 nationwide. In addition, up to now, the total scale of China's 4G base stations exceeds 5 million, and the optical fiber access rate and 4G access rate of administrative villages exceed 98%. During the epidemic, more than 60,000 new 4G and 5G base stations were built. The Ministry of Industry and Information Technology predicts that the number of 5G base stations in China will exceed 600,000 by the end of 2020, which will realize continuous outdoor coverage of prefecture-level cities, key coverage of counties and towns, and indoor coverage of key scenes.

By directly comparing the number of 5G base stations with the number of 4G base stations, we know that up to now, the number of 5G base stations is 2.5% of that of 4G, and even by the end of the year, it can only reach 10%. According to the difference between the 5G band and the 4G band, the number of base stations in 5G should reach 500% of that in 4G, and the coverage of network signals can reach the same level as that in 4G. (5G waves are short, and the coverage area is much smaller than 4g, so more base stations are needed to cover a wide range. )

In other words, the current signal popularity of 5G is less than 1.5%, and it will not exceed 5% by the end of the year. If you look at it this way, the current popularity of 5G is actually quite low.

The second problem is solved. Must we start with 5G mobile phones this year? Of course not, because you might buy it as a 4G mobile phone. The reason is still the problem of signal coverage, and there is no 5g signal coverage. Even if 5g is connected in a busy area, it can become a 4g signal in two steps. However, if you have enough budget, want to be the first to experience 5G, and live in a city with priority coverage of 5G, then it is no problem to buy now.

Secondly, the popularity of 5G depends not only on network signals, but also on the popularity of the industrial chain, the most typical of which is smart terminals.

Smart terminal is the most typical smart phone. Nowadays, mainstream mobile phones still don't support 5G except iPhone. Huawei, Xiaomi, OPPO, vivo and other domestic mainstream 5G models have already supported 5G, and the terminal conditions are already in place. The latest iPhone still doesn't support 5G.

But at present, consumers have preferred 5G mobile phones? Not yet.

Look at a set of data:

China ICT Institute announced the domestic mobile phone shipments in March 2020. The data shows that in March 2020, the domestic mobile phone market shipped 21756,000 units, including 4G mobile phones1484,000 units; 5G mobile phone 62 1.5 million. From June 5438 to March 2020, the domestic mobile phone market shipped 48.953 million units, down 36.4% year-on-year, including 33.807 million 4G mobile phones. 5G mobile phones14.06 million.

Whether in March or the first quarter, mainstream mobile phones or 4G mobile phones.

In addition, let's talk about self-driving cars, which are not available on the market now, which also explains the problem.

The only better ones are medical big data and remote diagnosis. This time, it has played a role in the fight against the epidemic, with experts conducting remote diagnosis and treatment and centralized consultation. It has made great contributions to overcoming the epidemic.

To sum up, you should know the current popularity of 5 G. I hope my answer will be helpful to you. Thank you.

5G is the fifth generation communication technology. Compared with 4G, 5G has the characteristics of ultra-high network speed, ultra-low delay and ultra-wide connection. It can be said that 5G is a revolutionary technology.

The network delay of 5G can be as low as 1 millisecond, which is much faster than the stress reaction of human body (for example, automatic braking is faster than human reaction, reducing the dizziness caused by VR at present), so it can be widely used in automatic control fields, such as unmanned driving, industrial control, remote operation and maintenance, etc.

A major feature of 5G is to serve the "Internet of Things". At first, the development of mobile communication is applied to the communication needs between people, and then to the service application of accessing high-speed networks, which is inseparable from people.

And 5G has changed the old communication purpose and technology, made the application of "Internet of Things" more thorough, and also had a considerable impact on the domain name industry. Yes. Top-level domain names of related concepts have also been registered.
