Electronic enthusiasts eight o'clock early: Some people say that 4G has changed our lives, and 5G will change society. So what are the substantial changes that will be brought to society by 5G already on the road?
In this regard, Chinese Academy of Engineering academician He Hezhen said that the development of mobile communication from 1G to 4G is for personal communication, but 5G not only brings wider bandwidth, higher speed, 5G is more developed in its targeted applications. Scenarios, industrial applications and a large number of unknown application innovations.
For the 5G application scenario, Qi Hezhen pointed out that it is mainly located in the following two categories:
First, low latency and high reliability. The main application target is high-speed rail, and it is necessary to ensure smooth communication at a speed of 500 km/h in the future. The other is to realize the Internet of Vehicles. In the future, we will use 5G to help us avoid traffic accidents on the highway. In addition, the more fashionable VR, AR, virtual reality, and augmented reality are not only dependent on high bandwidth, but also have less delay. In the future, AR and VR have huge industrial applications.
The second is low power consumption and large connections. The goal of 5G is to support 1 million sensors per square kilometer. The IoT nodes can be connected to the Internet, which is a very high-density large connection. On the node, the reason for the Internet of Things is to adapt to the current industry 4.0, industrial Internet, and smart city, all of which require large-scale sensors. Nowadays, the Internet of Things is generally fragmented. In the future, smart cities need to achieve large-scale connections, and 5G can support such connections.
"These are the application scenarios and goals of 5G design. Of course, in the application of the industry, applications other than consumers do not necessarily start until 5G." He He said that the country is now pushing "Internet +" and China manufacturing 2025. Apply 4G to the industry. Nowadays, the mobilization of e-commerce has become very obvious. More than 80% of orders for some large platforms are initiated by mobile terminals. In the future, with the ability of mobile terminals in the 5G era to be stronger and the bandwidth is stronger, the terminal will connect to the cloud and it can do things. Will be more.
He Hezhen believes that the more important applications of the future 5G should be industrial applications, which is also a major business growth point for future operators.
In the 3G era, no one would have thought that WeChat would be so widely used in the 4G era. In the same way, which super applications will be born in the 5G era is also unknown. In Qi Hezhen's view, many applications are not good before product development. Many applications will appear after product development. "So I think that with this (5G) capability, the majority of users will generate more application innovation. ".
Hehe said that there are still many things that mobile communication can do in the future. For example, to help alleviate traffic congestion, through the integration of big data technology to produce real-time dynamic traffic flow map, convenient for drivers and ordinary people to travel. In addition, the future of mobile communications can even help you to see the status of PM2.5 in the real-time, to achieve the replacement of the PM2.5 tester.
Faced with the "ubiquitous" challenge brought by 5G, He He said that 5G should not only adapt to human communication, but also adapt to the Internet of Things. The Internet of Things is low-rate, low-power, high-reliability, and this is the terminal. Not the same, how to combine different terminal needs, this is a big challenge. Therefore, in the product development, you can not only pursue a single indicator, but also take into account multiple indicators such as power consumption, cost, and reliability.
