What's the use of 5G? Deep Interpretation of Three Scenes

Speaking of 5G, I believe everyone is familiar with it, but perhaps some people's understanding of 5G technology only exists in improving the network speed. Do you know what it can do? Maybe everyone will be a little confused. This paper will give several application cases of 5G technology from real life.

2065438+September 2005, ITU (International Telecommunication Union) formally defined three major application scenarios of 5G, namely eMMB, uRLLC and mMTC.

(1) EMBB (Enhanced Mobile Broadband) Enhanced Mobile Broadband.

This scenario is an upgraded version of the mobile broadband (mobile Internet access) that people use now, which mainly serves the demand of consumer Internet. In this case, the focus is on network speed. If the rate reaches above 10Gbps, it will serve the eMBB scenario.

(2)uRLLC (Ultra Reliable & Low Delay Communication) low delay and high reliability communication.

URLLC mainly serves the Internet of Things scenario. For example, car networking, drones, industrial internet, etc. In this scenario, the requirements for network delay are very high. At the same time, this scenario also requires high network reliability, unlike mobile Internet access, if the network is unstable, it will cause users' dissatisfaction at most.

(3) MMTC (Mass Machine Type Communication) Mass Internet of Things communication.

MMTC is a typical Internet of Things scenario. Such as smart manhole covers, smart street lamps, smart water meters, etc. There are a large number of terminals in a unit area, and the network needs to support the simultaneous access of these terminals, which refers to the mMTC scenario.

Next, let's take a look at the specific applications in these three scenarios.

Application of 5G in the Internet of Vehicles

The solution to urban traffic congestion is to obtain data, then do data analysis, and finally do data application. Through the further analysis and research of these driving data, we can master the law of traffic flow direction, control traffic lights, dynamically adjust the waiting time of signals, and improve the traffic efficiency of traffic intersections.

In addition to alleviating the driving problem, there is also the parking problem. Through the collection of parking lot data, traffic can also be diverted in time. These are the development plans of the Internet of Vehicles.

At present, the technologies widely used in the Internet of Things include LTE-V, NB-IoT, LoRa and so on. But it is not enough to support the Internet of Vehicles.

5G technology can solve these problems:

1.5G network can improve the timeliness of vehicle networking data collection. The 5G network has the advantage of ultra-low delay. The enhancement of re-perception ability can guarantee the real-time information communication between people, vehicles and roads, avoid the collision between people and vehicles during driving, collect road conditions in real time during driving, avoid traffic jams and eliminate many risks of human driving.

2. When the road is completely covered by 5G, dynamically collect speed information and issue driving instructions. At the same time, timely collect weather information and road abnormal information (such as animal intrusion, falling goods, falling rocks, etc.) and transmit them to vehicles for avoidance.

3. The key to solving urban congestion is to deploy 5G communication capability, camera video data acquisition, data analysis AI (artificial intelligence), 5G large bandwidth and massive data connection to meet the demand of data transmission.

Application of 5G in Networked UAV

The industry regards 5G and drones as the best "partners". Before welcoming 5G, drones were mainly personal entertainment applications, and their safety was often criticized. The ubiquitous networking, higher speed and lower delay of 5G make the application scope of UAV expand continuously.

Among them, the 5G logistics drone is considered to be a very promising 5G use case. Companies such as Amazon and Google have been testing drone delivery services. With the advent of 5G commercialization, the application of 5G logistics drones will be rapidly promoted.

What are the advantages of 5G UAVs?

1. In the field of UAV logistics, further improve the speed and reliability of express delivery. At present, Hangzhou plans to establish a 5G UAV MAN covering Hangzhou, and provide E2E solutions based on networked UAVs for smart logistics.

2. In addition, 5G technology will enhance the products and services of UAV operators and transmit a large amount of data with minimum delay.

Application of 5G in Smart Grid

Building smart grid is the general trend. However, the construction of intelligent distribution network through traditional private network has the problems of high cost and low flexibility; However, the traditional telecom public network has poor isolation, and it is difficult to meet the business needs in terms of security and communication delay.

5G technology can meet these requirements:

1. It is a new attempt to use 5G network slices to carry power grid services. The network resources of operators are provided to power grid companies on demand through isolated logical network slices to meet the differentiated needs of different power grid services for communication network capabilities.

2. Considering high performance, high reliability, isolation and low cost, it becomes an effective solution for intelligent distribution network.

Now more and more enterprises have launched smart grid applications based on 5G network slices, including Huawei and Ericsson.

Application of 5G in Smart Factory

Smart factories have become a typical application of 5G. In some smart factories at present, replacing workers with robots can reduce costs and improve efficiency, but it does not solve the core problems for enterprises. In the future, it is not the manufacturing ability of robots that will determine the overall efficiency of enterprises, but the control ability of the whole manufacturing, transportation, warehousing and sales links.

5G will bring new changes to smart factories:

1.5G network will promote the development of artificial intelligence technology, and industrial robots will also make progress.

The characteristics of low delay, large connection and high speed of 2.5G network can meet the requirements of precision and strength in industrial manufacturing process, and people will be more sensitive to the control of robots, making the factory realize automation.

3. The collection and transmission of production data will be more timely, so as to grasp the production information more quickly, analyze it and make corresponding plans.

Application of 5G in HD video and live broadcast

5G will create a unicorn in the field of ordinary consumers. Enterprises may be concentrated in the video field, probably in the video social field.

Advantages of 5G:

1. 5G brings users the ultimate audition experience.

2. In terms of live video transmission, the low delay and stability of 5G reduce users' viewing troubles.

On 20 19, the main venue of CCTV Spring Festival Gala and Shenzhen Branch conducted 5K4K ultra HD video live broadcast, and the picture was smooth, clear and stable. The Beijing-Zhangjiakou Winter Olympics in 2022 will also make full use of 5G for live broadcast of major events and important sports events.

Application of 5G in Smart Medical Care

The embodiment of 5G in smart medical care is multifaceted. Here we list two typical scenarios:

1. Under the 5G network, the efficiency of mobile rounds and mobile nursing can be improved. Doctors can input, query and modify electronic medical records at any time, and can also browse large medical documents such as X-rays at any time.

2. With the advent of the 5G era, telemedicine based on 5G stable low-latency network will change the medical status in remote areas and narrow the gap of medical resources in different regions. For example, every delay 1 minute in defibrillation will reduce the survival rate by 7% ~ 10%. The low latency (1ms) and ultra-high reliability provided by 5G just meet this requirement.

At present, the application of 5G network in telemedicine in the United States has begun to take shape. Take Kansas Children's Hospital as an example. Of the 47 pediatricians in the hospital, 26 have established contact with children in Kansas City through the Internet.

Application of 5G in Smart Agriculture

According to the statistics of FAO, in order to feed the growing population, farmers around the world will have to produce 70% more food in 2050. This sounds like an almost impossible task, because the environment is deteriorating.

With 5G, all these problems can be solved.

1. With 5G high-speed network and various sensors, the factors that affect crop yield, such as soil moisture, temperature and fertility, can be monitored at any time and processed in real time, thus improving crop yield.

2. It can save labor cost, reduce labor demand and improve farm operation efficiency.

Application of 5G in Smart Home

Smart home has been mentioned for many years, but it has been difficult to land. 5G can completely change the deployment and service mode of smart home terminals, and it will solve some major problems of consumer complaints.

The number of 1.5G connections is huge, which can meet the simultaneous access of a large number of smart homes in the family and solve the difficulty of terminal setting.

2. The communication capacity is large, so there is no need to worry that individuals cannot communicate due to too many and too dense connected devices.

3. Device 5G network effectively solves the difficulty of terminal setup.

4. Solve the problems of unreliable equipment and high time delay existing in smart homes before, so that smart homes can truly shine into reality.
