With the advent of the 2018 era and the advent of the 5G era, the era of the Internet of Everything is about to form a trillion-level market. Under such a background, there are three major power switches to drive the development of the market. 5G changes society, technology demand drives 5G accelerated iteration, and 5G helps all things interconnect.
If a car is traveling at 100 kilometers per hour, a network delay of 30 milliseconds means a moving distance of 83.33 centimeters, while a moving distance of 1 millisecond is only 2.78 centimeters. In fact, many traffic accidents occur between this idea. Data shows that the average brake response time of drivers is about 0.8 seconds. The rapid response capability of automatic driving under 5G network is better than that of humans.
In the Shanghai test site 1,200 kilometers away, a real car is being connected to the long-distance driving platform in Beijing via the 5G test network. Starting, accelerating, turning, the vehicle in Beijing remote control Shanghai is not much different from the real-time driving experience. The ultra-low latency of 5G guarantees the safety of daily driving habits in remote operation, and the ultra-high speed also makes the car HD camera The external environment is transmitted back to the control screen in real time.
Not long ago, at a communication exhibition in Beijing, a 5G long-distance driving platform jointly built by Huawei, China Mobile and SAIC Group became the most eye-catching focus of the audience.
It will not take long for this prototype to open its exhibitions and test sites, enter people's daily lives, and enter the oncoming 5G era.
Under the two-wheel drive of technology and demand, 5G is accelerating. The intergenerational transition of mobile communication technology often leads to an exponential increase in system performance, and it has spawned new business that has emerged in an endless stream, becoming the iconic scale of social progress. 5G will achieve 100 billion-level connectivity, 10Gbps speed and latency as low as 1 millisecond, which will bring ultra-high-definition video, virtual reality and other extreme communication experiences, and more likely to detonate multiple verticals such as Internet of Vehicles and Industrial Internet. The rapid development of the industry.
Compared with the previous people's main connection target, 5G pays more attention to the connection of objects: in the three scenes of 5G, the two major scenes of massive machine communication, low latency and high reliability communication are mainly objects. Large connectivity, wide-area coverage and lower power consumption enable the Internet of Things, represented by smart cities and smart homes, to integrate with mobile communications. 5G will also be widely used in remote control, autopilot, factory automation and other fields. Thousands of devices will be connected to the 5G network. The era of the Internet of Everything is coming out.
In the future, 5G will likely become a general-purpose technology, like power and the Internet, as a catalyst for changes in many industries. This will open up trillions of market space. Some analysts predict that by 2030, the total social output and economic value added by 5G will reach 6.3 trillion yuan and 2.9 trillion yuan respectively, and 8 million jobs will be created. By 2035, 5G will create 123,000 yuan worldwide. The economic output of billions of dollars.
Technical requirements drive 5G accelerated iterationSince the 1980s, mobile communications have evolved at a rate of once every ten years or so. Following this rule, mobile communications is now striding towards the 5G era.
Throughout history, the intergenerational transition of mobile communication technology has often led to an exponential increase in system performance, and has spawned endless new business, becoming the iconic scale of social progress.
From 1G to 2G, mobile communication has completed the transition from analog to digital, and on the basis of voice services, it has begun to support low-speed data services. From 2G to 3G, the peak rate exceeds 2Mbps, supporting mobile multimedia services such as video telephony. 4G transmission capacity is an order of magnitude higher than 3G, and the peak rate can reach 100Mbps to 1Gbps. The upcoming 5G will provide peaks above 10Gbps, millisecond latency and ultra-high-density connectivity for a new jump in network performance.
Wei Kai, deputy director of the Mobile Internet and Big Data Department of China's ICT, told 21st Century Business Herald that under the joint promotion of technology and demand, 5G is rapidly advancing.
Technically, he said that 5G will replace traditional bandwidth with more sophisticated algorithms and higher computing power, and improve communication capabilities with rapidly evolving IT technologies.
He said that Moore's Law (that is, every 18-24 months, the number of components that can be accommodated on an integrated circuit will double and the computing performance doubled) continues to play a role in the communications field, now on the transmitter side. The receiving end can use computing power to improve the efficiency of communication.
Li Shan, vice president of wireless and mobile in China's ICT, said that the biggest difference between 5G and previous generations of communication is that the latter has a core technology, such as 3G with CDMA, 4G with LTE, but 5G with this. Rather, it improves performance by meeting a diverse set of technologies to meet diverse needs. For example, the use of large-scale antennas to increase the network transmission rate, the use of dense networking to meet the needs of hotspots, to reduce the delay and cost by simplifying the air interface structure and network structure.
At present, 5G technology has identified 8 key capability indicators: peak rate reaches 10Gbps, spectrum efficiency is 3 times higher than IMT-A, mobility is 500km/hour, delay is as low as 1m, user experience data rate reaches 100Mbps, and connection The density reaches 10 to the 6th power per square kilometer, the energy efficiency is 100 times higher than IMT-A, and the flow density reaches 10Mbps per square meter. The first four are traditional indicators, and the last four are new indicators.
Due to the diversification of key indicators, 5G can support eMBB (enhanced mobile broadband), mMTC (mass machine communication), and uRLLC (low latency and high reliability communication) in a single scenario with respect to 4G. This enables 5G to meet the ultimate experience of VR, ultra-high-definition video, and support massive IoT device access to meet the stringent requirements of car networking and industrial control.
In Wei Kai's view, the development needs of the above-mentioned industries are another major driving force for the rapid development of 5G.
Taking the ultra-high-definition industry as an example, Xu Zheng, a professor at the Institute of Optoelectronic Technology of Beijing Jiaotong University, told the 21st Century Economic Reporter that at present, in China, ultra-high-definition video, panel and other terminals are no longer a problem, but the biggest bottleneck of the product is the front-end transmission, 5G. The landing is conducive to breaking this bottleneck.
High speed is the primary feature of 5G, and its network transmission rate will reach 10Gpbs, which means that users can download a 50G ultra-high definition video in 40 seconds when using 5G, which is ultra-high definition video such as 4K/8K, VR/AR, Fast downloading, cloud services and other industries provide strong technical support.
