From 2G, 3G, 4G to 5G, from 20M, 50M, 100M to Gigabit, in the invisible corner, Internet data transmission is getting faster and faster; in the visible daily life scene, travel, shopping, medical Even new ways of entertainment have changed due to high-speed data transmission.
As Shanghai enters the ranks of the Gigabit City, people's lives will enter a new era.
4G full coverage? not enough!
Gigabit energy cities bring more technical and commercial breakthroughs
Shanghai, as the first international demonstration city for electric vehicles, has the first international demonstration zone for EVZONE electric vehicles. Now, here is a new experiment in the Internet sharing car revolution, which requires the support of a more efficient network.
Behind the shared cars running in the streets, there are countless numbers of data running - the start of the vehicle, the speed of the road, the direction, and even the length of the vehicle failure... the speed of data transmission, the coverage of the communication network, will determine the smart car network Calculation and real-time transmission efficiency.
How to ensure that each car's data is collected in real time, and the information data of the vehicle and the vehicle, the vehicle and the data center are shared in real time, thereby ensuring that the single vehicle is sufficiently safe and intelligent, which is the direction of change that EVCARD is currently striving to achieve.
As the nation's largest shared-car company, EVCARD currently has 10,000 rental outlets across the country, launching more than 26,000 new energy vehicles. This "old" shared car company is more expecting the 5G, Gigabit high-speed network era than its peers.
"Despite the popularity of the current 4G network, 2G signals will continue to exist for a long time. Especially in remote areas, 2G signals cover a wider range." Xu Jiang, deputy general manager of EVCARD, told the "IT Times" reporter that it is currently receiving transmission bandwidth. The restrictions are that they offer different services in big cities such as Guangzhou, Shenzhen and Chengdu, and cities in the second and third tier cities. In the 4G signal coverage area, they explore new business models and topics, such as how the “last mile” remotely controls the information, allowing the car to independently complete the search for parking spaces, parking, and even charging; or use the user to stay in the process of returning the car. In a dozen seconds, real-time big data analysis, including user spending habits, the surrounding environment, etc., accurately deliver nearby merchant advertising information to the vehicle terminal, providing practical services for users while also exploring deeper business models. However, even in areas where Shanghai's 4G signal is well-developed, 4G network coverage and signal transmission rate will be greatly reduced due to the impact of viaducts, dense buildings and multiple underground parking spaces. It is difficult to carry EVCARD's rich business model. Imagination.
And the changes brought about by the upcoming Gigabit bandwidth communication infrastructure network will subvert the traditional dilemma.
As the real-time remote transmission efficiency of data increases, vehicles traveling on the road will become more "smart" - the front camera can help the user to determine whether a lane offset occurs, and the temperature sensor monitors the vehicle's battery pack too high in real time. By collecting the strength and opening and closing degree of the user to step on the brake, the background can calculate the acceleration of the car, thereby confirming whether there is a problem in the brake system, and the background can be able to prompt the user or limit the speed in real time.
"These must rely on communication." Xu Jiang said frankly: "These scenes cannot be achieved by relying on the meager computing power of the vehicle. They will rely on high communication bandwidth and a stable communication network to allow vehicles to transmit data to the rear in real time. The huge computing power, through complex calculations to judge the operation of the vehicle." That is to say, in the Gigabit era, in the face of complex and diverse user driving habits, road conditions, traffic environment, the background of the Internet of Vehicles will be able to do real-time Monitoring helps users reduce the incidence of accidents and improve the efficiency of processing afterwards.
How to build an AI brain?
Gigabit is the foundation, high bandwidth to create the "eyes" of smart cities
The outbreak of artificial intelligence application will promote the change of everyone's daily life. The most mature one is the “brush face” technology, which pays for face payment, brushing face into the venue, and brushing face through customs. “Face” is replacing The traditional way of identity authentication for documents enhances the efficiency of social operations, and behind it is also inseparable from the high-speed network foundation.
Defiance Technology, which provides technical support for 80% of the nation's face verification services, is an AI startup that moved from Beijing to Shanghai. In their view, high-precision, high-efficiency real-time transmission of face images is an important direction for the future development of face recognition. Xie Yinan, vice president of Vision Technology, believes that in large-scale, large-scale crowd identification in public, robots must be better than humans - humans can only rely on feelings to make judgments, while machines can pass sensors and algorithms. Feel accurate quantification, the process is 2-3 times faster than people, and even more.
At present, face recognition technology and image recognition technology independently developed by Vision Technology have been applied to public administration departments such as the Ministry of Public Security and the State Administration of Taxation. In the future, face recognition will become the "eye" of urban intelligent control.
How to improve the sensitivity of the "eyes"? Independent research and development and industry integration are two important factors in Xie Yinan's brain planning map, which coincides with the future development of Shanghai's cities. Shanghai has both AI professional academics represented by Jiaotong University and unshakable commercial status. “AI will be deeply integrated with traditional industries such as manufacturing and finance, so the research of artificial intelligence should be based on the market, and the academic and market should each occupy half of the future research direction.”
At the same time, entrepreneurs like Xie Yinan are more aware that they want to push AI technology to a deeper industry integration, and they cannot do without a stable and efficient network bandwidth base. From 3G to 4G, the increase in network speed has enabled people to consume content online, from text, pictures, and even today's videos, while also transforming a series of business practices. In the Gigabit era, all areas will be completely affected. "Band is a very important transmission channel in the process of building the program brain with AI. The performance of the communication infrastructure will be improved, or it will subvert the gameplay of the entire AI industry. The control of urban intelligence affects the gameplay of each industry, and the cycle advances. Progress in all areas of society."
"Like the real-time 3D map in the movie "Western World", the augmented reality based on 3D data will appear in people's lives in the future." Xie Yinan looks forward to the realization of the future reality of the human being in the future. In the world, real-time feedback on monitoring data is achieved through machines.
It is understood that since the Shanghai Municipal Government issued the "Implementation Opinions on Promoting the Development of a New Generation of Artificial Intelligence" in November last year, Shanghai is accelerating the development of the artificial intelligence industry.
Up to now, the scale of artificial intelligence-related industries has reached 70 billion yuan, involving transportation, finance, commerce, security and many other aspects. Tencent, which just announced the establishment of East China headquarters in Shanghai, also said that it will establish a park related to artificial intelligence-related industries in Shanghai, and strengthen technological innovation in machine learning natural language processing, image recognition, pattern recognition, machine learning, computer vision, etc. Promote the application of artificial intelligence technology in medical, transportation, retail, security, police, and people's livelihoods.
