5G communication systems and consumer scenarios of things, a comprehensive analysis of industrial networking applications scenarios
A, 5G application scenario of the communication system
What 5G arrival mean? High rate (enhanced mobile broadband, embB), a large capacity (large-scale machine communication, MMTC), low latency (high reliability and low-latency communication, URLLC) is the basic characteristic 5G networks, and may be implemented in the per km access one million devices, while huge technological breakthrough propagation delay, can achieve the objective "millisecond delay." It Is, therefore, 5G will greatly accelerate the fall of various types of new applications of smart technology, open a new era of mobile communication development, promote a full-motion, full-connection building society.
Reviewing the development of mobile communications, every generation mobile communication system may be defined by both capabilities flag indicators and key technologies, wherein, 1G provides the analog voice only service; 2G provide voice and low-speed digital data services; 3G user peak rate reaches 2Mbps to several 10Mbps, supports multimedia data services; 4G mobile broadband capable of supporting various data services. 5G while the high speed connection, the high density large capacity and low latency constitute three basic performance.
From these key capabilities. 5G, 5G make all foreseeable Internet or will become a reality, smart city, smart home, car networking, autopilot, VR, AR scenarios such as network environment to get support, to people's lives as well as the industry has brought influence and promote the upgrading of business. Key capabilities of the technology often determines the scope of its application. 5G standards in the International Telecommunication Union (ITU) established (IMT-2020), that from these three key indicators as the basis 5G, 5G divided future scenarios.
Wherein the enhanced mobile broadband, is to the human-centered application scenario, centralized performance ultra-high transmission data rate, and the like to ensure wide coverage mobility under. In short, the most powerful of which is a key capability 5G service to connect people and persons and things, mobile communications and social scene will be the position of the main application. 4G era, allowing users to watch video on mobile end consumer entertainment content becomes habit. 5G enhanced mobile broadband era, is likely to subvert the previous model to create content once again, social interaction and industrial ecology. 4K high-definition TV, VR, AR, 3D video, cloud and other scenes of the office, also eagerly looking forward to a positive change in connection 5G this level brings.
Demand for high reliability in the scene low latency connection, high reliability (99.999%) in milliseconds connection delay and high-speed movement (500KM / H) connected to the case, so that the vehicle network, industrial things, telemedicine, smart manufacturing, and other special applications more realistic. Studies have said that car networking market has great potential, 5G era piece of cake will reach $ 600 billion, and the communication module which accounted for more than 10%, a very high security requirements of these applications.

And large-scale machine communication, also be interpreted as the mass of the IOT. This makes the 5G powerful connectivity can quickly promote various vertical industries, such as smart city, smart home, environmental monitoring, integration and vertical depth of field. In the future interconnection of all things, people's way of life will occur disruptive change. Under this scenario, a low data rate and delay insensitive connection cover all aspects of life, lower cost of the terminal, longer battery life and higher reliability.
On the whole, compared to previous generations of mobile networks, 5G breakthrough on key capabilities make application scenarios will also have the richness of rapid development. In addition, 5G provides an attractive business model for mobile operators and their customers. To support these business models, the future network must be able to different service levels and performance requirements, efficient delivery of new services. Research institutions 5G era summed up the top ten most market potential scenarios, it is nothing less than to change due 5G key capabilities in the mobile communications addressed connection speed and quality brings.

Two, 5G communication system consumption IOT
IOT (Internet of Things, IoT), the Internet, telecommunications networks and other traditional information carrier, so that all can exercise independent function of common objects to achieve interoperability of networks. In the Internet of Things, everyone can use electronic tags to real objects Internet link, the Internet of Things can find out their specific locations. It may be the central computer of the machine, equipment, personnel through centralized management of things, control. Currently, most of the investment and application of the Internet of Things focused on industrial networking, including manufacturing, logistics, healthcare, agriculture, automotive and other industries. Things Consumption (CIoT) is a class of consumer applications of things, we are usually the most contact with the program, and use cases collectively set of devices. According to the research company said, smart home consumer use case things most important consumer products.
For the consumption of things, the biggest problem lies in the experience, the number of terminals currently too intelligent, it is difficult to experience the advantages of smart home, according to the report, in 2018 the average number of households intelligent home devices China is only 0.9 units, 2022 Taiwan is expected to reach 2.8 in 2025 is expected to reach 6.8 units.
5G arrival, things can be said to "wings", especially unmanned, remote medical, industrial automation network for these demanding applications forms for, let these 5G is expected to become a reality. 5G compared to 4G, with higher rates, wider bandwidth, higher reliability, lower latency and other features to meet the future of virtual reality, ultra high-definition video, intelligent manufacturing, autopilot and other consumer and trade Application requirements. 5G flexibility to support a variety of different devices. In addition, IPv6 (Internet Protocol Version 6) is used, not only to solve a number of network resources to address the problem, but also to solve a variety of obstacles to access devices connected to the Internet. These are so Bill Gates in the 1990s envisioned "future house" likely "flying into the homes of ordinary people."
G is through the ages, "PC era, a man who is ready to connect the mobile device is connected and the people whenever and wherever, WIFI age is from person to person, linker and object, 5G era will achieve human and material, things and objects connected anytime, anywhere. "things in the consumer scene, appliances profit model will change, the traditional home appliances or redefined.
Three, 5G communication systems and industrial IOT
3.1 5G impact on the industry of things
For ordinary consumers, the concept 5G is probably higher network speed, large bandwidth 5G enhance the Internet experience to bring the most intuitive, using a mobile phone can watch higher-definition video in real time.
The lower latency and higher reliability of the C-terminal users experience improved, relatively speaking, a lot of small, open page latency is reduced from 50ms to 10ms, the consumer is basically imperceptible differences.
In industry, many years ago, the concept of the Internet industry had already been made, but until now the mobile Internet so popular, the proportion of industrial networking equipment is still small, application networking devices involved are also very shallow. The main reason is that the current Internet latency and reliability also below standard.
Things in the industrial field, the situation is not the same. Various industry verticals industry characteristics are different, high barriers to knowledge, but also for industrial manufacturing processes require very high reliability and stability, the current operator's network also difficult to meet the industry Things to performance requirements. So things in the field of industrial progress has been relatively slow, has not produced a more mature business model and the relative amount of the Company generally.
Industrial areas include numerous vertical industries, large industries have huge differences in characteristics of manufacturing, transportation, energy, construction, mining and other industries, each industry, combined with each of Things industry, but also must be based on the industry itself feature to adjust.
Things industrial purpose is to be able to precisely control the industrial process embodiments. Based on the sensor data acquisition, display, modeling, analysis and application process, the decision-making in the cloud formed, and converted into control commands industrial equipment can be appreciated, the operation of the industrial equipment, provide precise information between the industrial device resources interactive and efficient collaboration.
Most of the current scene of industrial control systems also need to be deployed locally restricted communication technology and processing power, industrial cloud platform involving industrial control depth is not enough. 5G technology can meet industrial systems through to industrial areas, the high reliability and low latency communication system can be said to be critical.
Application of things has been the industry will remain at the surface of the data acquisition and display a number of management functions extending therefrom, it is difficult to relate to core areas such as industrial control systems, communications systems which can not reach stability and delay requirement is one of the major constraints. Letter capability requirements, goals for industrial control.
Current mobile communication systems involved in the field of industrial applications of things are not in-depth, although on 4G speeds have been greatly improved to meet the needs of users to watch video, but the network's reliability and latency are still great room for improvement, and can not meet the requirements of the industrial scene. These industries demand for communications systems, technical standards for 5G can well meet the extremely low latency, real-time to ensure that the requirements of industrial monitoring and control; highly reliable network quality to ensure the stability of the industrial system requirements; large bandwidth you can achieve high-definition 3D video, and even transmission of AR, in the field of remote control of a substantial increase in operating precision.
