What will 5G bring?
Data is productivity
This topic begins with the data being productivity.
After the introduction of artificial intelligence in 1956, after several decades of development, neural networks, algorithms, and pattern recognition have matured in theory, but artificial intelligence has not formed a real application. It was not until 2016 that AlphaGo represented the emergence of new applications that artificial intelligence became productive.
There are two reasons for this change. One is that the Internet has a large amount of data, and the other has a large computing power. The original computing power can not adapt to the multi-layer neural network nesting, and now some artificial intelligence enterprises can use more than 4000 layers of neural network nesting, computing power and a large amount of data to support artificial intelligence into productivity.
Although the data is so important, the data we are getting now is only the data obtained from the consumer Internet, just the data related to people's lives, it is only a fraction of the objective productivity data.
Goods currently sold in supermarkets and online have unique identifiers and related product information, which is only a very small part of the life cycle of this product. These goods generate a large amount of data in the production process, from demand to design to production, to logistics and transportation, etc. It has various links, the data of the machines involved in these links, human data, Material data, various cloud and rule data, and environmental data. If you extract this data from the machine, it will be much larger than the data that is currently consumed by the Internet.
What if I extract this data?
In the future, that is, in the era of 5G networks, large technology companies can form an industrial Internet in a single industry because it has many supply chains and many production lines that generate a large amount of production data and management data. If these data are organized, through the optimization of artificial intelligence experts, an industrial Internet platform of an industry can be formed, and finally, the machine that directly orders the production instructions to the production line can be issued to the partners and the machines of various links according to the order requirements. Achieve global synergy of billions of large-scale production factors.
The necessary premise to achieve this goal is to use 5G to mine, extract, transfer, and collect data, so 5G is the source of the data industry revolution. Everyone often said that the big pipe is what this means.
Why is 5G?
So why is this goal 5G?
First of all, it is the high reliability of 5G, it will not lose packets, or it will have less packet loss.
Packet loss is simply a loss of information during data transmission. Taking the call as an example, some calls can barely be heard, but some calls are clear and the sound quality is high and fidelity. The difference between the two is the degree of data loss. If I use the 2G communication network to make calls, its guarantee rate is generally 99.999%. If I use WeChat to make a call, it may lose more than 2G calls.
In the current general application, packet loss does not affect our use of data, such as the phone, even if it is not clear, can still talk. However, if the data is transmitted in industrial data or in some very important applications, once the packet is lost, the command received by the machine will be a breakpoint, which will have a significant impact on the operation of the machine.
Since the network we are using now has packet loss defects, some related technologies have been derived for this. For example, the download tool BT of our commonly used network resources, the more people download, the faster the download speed. Its principle is to capture multiple network resource fragments, even if these resources are incomplete, there is a very serious packet loss rate does not matter, and finally through the calculation of all the data stitched together, a complete download package is formed.
But such Internet data is easy to be crawled, converted, and replaced. When the packet loss is serious, the travel app was originally downloaded, but it may be replaced by an Internet as an advertising app. Therefore, our network quality is not high now, and we can't complete some high-precision machine control.
The characteristics of all 5G packet loss rates are significantly different from the networks we used before.
Second, the 5G delay is shorter.
Many people know this, 5G data interaction time is 1 millisecond, 4G may be 50 milliseconds. The most common short delay is the delayed connection between the mobile phone and the 5G base station.
What is the use of short delay? If I control a UAV in Shenzhen through a remote network in Beijing, I will transmit real-time video of a moving target in Shenzhen to Beijing, and then remotely control the target based on this data. If it is through 4G or other Internet network, because the delay is longer, reaching more than 200 milliseconds, the target is lost when the instruction to fire is executed. However, if it is a 5G network, because the delay is very low, the command and the reality are almost synchronized, and a high-speed mobile remote attack can be completed.
Low latency makes many remote controls a reality. For example, if you do surgery remotely, if you do not have the high-security and low-latency characteristics of the 5G network, you will not be able to do telemedicine. The distribution of medical resources in China is uneven, and patients in remote areas do not receive the best treatment. If you want to be an emergency, telesurgery and telemedicine will become life-saving straws.
Third, the speed of 5G is more than 10 times that of 4G, which enables instantaneous transmission of large amounts of data. Compared to 4G, the first problem that 5G has to solve is high speed. The network speed is increased, and VR and Ultra HD services need to transmit a large amount of data in an instant to meet the technical requirements. Those services that require high network transmission rates can be widely promoted and used. The 5G peak theoretical transmission speed can reach 1Gb per second, and a 1G movie can be downloaded within 8 seconds.
More importantly, in the 5G network environment, holographic image communication utilizes the characteristics of high-speed transmission to transmit large amounts of 3D video signals, which can present a more realistic world for users and achieve a qualitative leap in interactivity. The holographic display technology under the 5G network will enable comprehensive changes in games, e-commerce, and even medical, military, and educational fields.
Fourth, 5G has a large connection capability.
Under the current network conditions, if large-scale concerts or large-scale events are held, in order to maintain the communication needs of high-density people on the site, operators need to send communication emergency vehicles. Because 4G base stations can connect up to 100,000 units in a square of 1 square kilometer, congestion will occur if they are exceeded. A 5G base station can provide services for at least 1 million devices.
The extraction of data in the above production process requires a large number of people, machines and materials to be connected together. Production factors such as machines, parts and machine tools have their own production mechanism and logic, requiring high synergy. , you need the ability to connect with this big connection. This is what people often say about the Internet of Everything.
In addition, 5G can also implement cloud networks.
Cloud computing is a combination of a large number of computers to form a total virtual machine. The computing power, network capabilities, and storage capabilities of such virtual machines are fragmented. The 5G network can be a cloud network, which can be personalized and sliced.
This new technology allows operators to segment multiple virtual end-to-end networks in a single hardware infrastructure. Each network slice is logically isolated from the device to the access network to the transport network to the core network. Different feature requirements for type services. For each network slice, dedicated resources such as virtual servers, network bandwidth, and quality of service are fully guaranteed. Since the slices are isolated from each other, a slice error or failure does not affect the communication of other slices. Due to these important network features of 5G, it has the characteristics of an editable cloud.
5G is Now
Such a unique 5G enables us to obtain much more data from the objective industrial world, the industrial world and urban management than the current network, and data productivity will trigger a series of changes.
Our current network, from 2003 to the present, has led to a major outbreak of the consumer Internet industry after 16 years of accumulation.
In the future, the data of the industrial Internet or the industrial Internet industry will be detonated, and it will be extracted by the 5G network.
Today, we extract huge amounts of offline data through 5G, just like we have dug coal and oil in the industrial age!
