With the distribution of 5G licenses and the upgrading of international competition, 5G has become a hot topic that is well-known to all ages, and everyone has placed great expectations on 5G.
For example, the VR experience is not good, and it is easy to feel dizzy. What should I do? Noproblem, after the emergence of 5G, the latency is reduced to milliseconds, and the immersive experience is no longer a rhetoric.
For another example, a female driver is nervous and can't stop. What should I do? Noproblem, after the emergence of 5G, autonomous driving is not a dream, and everyone can easily get on the road without a driver's license.
For another example, although there are many surveillance cameras, it is OK to capture violations, and they are not very effective when solving the case. What should I do? Noproblem, after the emergence of 5G, with the powerful network transmission and big data and AI capabilities, criminal suspects can fly into the sky. The earth can make him invisible.
The omnipotent 5G, what a bright future, everyone can’t wait to apply 5G. But wait, is 5G really all-powerful enough to deal with all problems and make the city full of wisdom overnight?
1. After the rapid development, smart cities enter a period of adjustment.
As the scale of cities gradually expands, “big city diseases” such as traffic congestion, environmental pollution, and inefficient management methods continue to appear. For this reason, in 1994, New York gradually began to build a wireless city, and Stockholm proposed a data network infrastructure construction plan in order to improve city quality and management efficiency through technical means. These are all regarded as the embryonic form of a smart city. In 2008, IBM put forward the concept of Smart Earth and using new technology to promote social and economic development, and soon gained recognition all over the world, and the concept of Smart City was formally formed.
In our country, the urbanization level exceeded 50% for the first time in 2011. At the beginning, only a few large cities had to face traffic congestion, environmental pollution, safety guarantees, management methods and other issues. Nowadays most cities need To solve the problems together, to create a safe, efficient, convenient, green and smart city has become an urgent need for urban management.
Therefore, after 2011, many cities have gradually begun to embrace the wave of wisdom, and smart cities have sprung up continuously. Especially from 2013 to 2015, relevant policies, guidelines and pilot plans were intensively released, setting the tone for smart city development from the top-level design. In terms of regions, smart city design and planning, infrastructure construction, and public service projects have also been actively promoted. After a lot of hard work, the number of smart cities in my country has soared. According to incomplete statistics, there are already more than 500 smart cities in my country, which are far ahead in scale in the world.
After the outbreak is adjustment. IResearch believes that at this stage, smart cities have entered the stage of objective exploration. When the speed slows down, the problems in the construction of smart cities such as lack of experience and practical utility, fragmented development, insufficient construction funds, and difficulty in continuous operation, have gradually emerged.
From the perspective of the user’s personal application experience, although many cities in my country have proposed smart city plans, ordinary citizens can experience not much. Smart applications are still the moon in the mirror and the flowers in the water, and the leader vigorously promotes , The phenomenon of "two skins" that users respond dull is obvious.
2. Ask the pulse and prescribe the right remedy.
After the initial rush, the development of smart cities has entered a bottleneck. In order to overcome the bottleneck of development, we need to consult the pulse and prescribe the right medicine.
As we all know, smart cities involve many links such as government departments, various enterprises, construction parties, users, etc., covering many industries such as government affairs, medical care, education, finance, and transportation. It is necessary to find the main problems of smart cities. , Difficult to conquer.
However, after the emergence of 5G, the industry will pin its expectations on 5G, which has high bandwidth, low latency, and large connection characteristics, which seems to be omnipotent. Especially with the distribution of 5G licenses and the three major operators accelerating the pace of 5G network construction, it seems that all the problems can be solved after the advent of 5G. But in fact, the problem is not so simple.
Take the NB-IoT network recommended by the Ministry of Industry and Information Technology and the three major operators to build smart cities as an example. In order to increase the intensity of NB-IoT construction, the Ministry of Industry and Information Technology issued policy documents such as the "Notice on Comprehensively Promoting the Construction and Development of Mobile Internet of Things (NB-IoT)", and the three major operators have also accelerated the pace of construction. For example, at the "2019 Quectel IoT Ecological Conference" held in March 19, Huang Chaoping, director of the Guangdong Mobile Intelligent IoT Center, said: At this stage, China Mobile has built more than 200,000 NB-IoT base stations across the country. Covers 346 cities.
Although the speed of NB-IoT network construction is considerable, the network utilization rate is not high, and the limited case scale is not large. The largest single NB-IoT project that has emerged at this stage is the smart electric vehicle deployed by China Mobile in Zhengzhou, with a scale of 3 million.
In the development of NB-IoT, the most criticized problem in the industry is the high cost of modules. At this stage, the cost of Wi-Fi modules is less than 10 yuan, and after years of hard work in the industry chain, and after strong subsidies from operators in recent years, the price of NB-IoT modules has dropped to about 20 yuan. But it is still at least twice as expensive as Wi-Fi. For low-income scenarios such as utility meters, the module cost of 20 yuan is unaffordable for users, and therefore there are few promoters. The high module cost has also affected the large-scale popularization of terminals. Many users report that they intend to use NB-IoT services, but there is nowhere to buy NB-IoT cards.
The high module price has led to not many users, and the lack of users has affected the decline of module prices. This "chicken and egg" problem may be difficult to solve after the advent of 5G. Because it will take some time for the cost of 5G modules to fall, and because 5G is a new technology, this process is destined to be even longer.
In fact, high module costs and insufficient user willingness are not the key to affecting the development of smart cities. Data islands due to incompatibility of projects and lack of sharing between different departments, industries and regions are the obstacles to smart cities. The main sticking point is.
3. Data islands are serious, and the development of smart cities has hindered the
construction of smart cities in the past few years. Many departments and industries have built small-scale smart city projects, but the problems of segmentation, separate governance, and repeated construction are serious , The data lacks effective integration, and data islands have been established.
Connections generate value, and isolated data islands cannot realize the potential of data. However, due to the lack of integration, data cleaning, data desensitization, data analysis, etc. cannot be carried out, and it is difficult to produce valuable operation plans to achieve the goal of intelligence and intelligence.
Nowadays, government departments have understood the seriousness of the data island problem and have encouraged various departments, industries, and regions to establish interconnection mechanisms and achieve unified access from the macro policy level.
So, is there a way to break data barriers and realize interoperability without repurchasing smart city facilities and equipment? The answer is yes. On each data island, all products can be adapted to achieve data sharing and interoperability. Networking platform is the best weapon to crack data islands.
4. OneNET helps to eliminate platform shortcomings.
Today, the main builders of IoT platforms include Alibaba Cloud represented by Internet companies, Huawei Cloud represented by communication equipment vendors, and China Mobile OneNET represented by operators.
In the new era of 5G, in terms of cracking data islands and promoting the development of smart cities, OneNET of operator pedigree has significant advantages. OneNET is an open platform for the Internet of Things at the PaaS layer created by China Mobile. It solves common problems in application development such as protocol adaptation, massive connections, data storage, device management, rule engines, event alarms, etc., reduces application development cycles, application development costs, and promotes Application innovation and upgrading of traditional enterprises.
OneNET 4.0 can adapt to most protocols, ensure the access of big data hardware products, use existing smart facilities to the greatest extent, and break the shackles between data islands, which is one of the best in China.
OneNET has a pipeline gene, making it easier to build a complete end-to-end empowerment of "cloud pipe end-to-end". For example, OneNET can provide privatized deployment capabilities, taking into account the needs of customers for security and data sensitivity. When OneNET and MEC were combined, OneNETEdge was born. The OneNETEdge solution has a strong edge capability, which complements the privatization deployment capability. Through cloud-side collaboration, the edge is empowered, as well as data analysis, processing, and refinement, which is also convenient for the future More facilities and equipment are connected to data centers and Internet of Things middle stations, making more smart city application scenarios possible.
OneNET keeps pace with the times and combines with AI to form OneNETAI capabilities. OneNETAI provides face detection, face comparison, image meter reading, license plate recognition, image content evaluation, image enhancement, image defogging, motion detection, virtual reality And other AI capabilities, using APIs, provide smart city solutions that are closer to users, empower emerging applications in various industries, and promote people to enter the new AIoT era as soon as possible. In addition, smart cities have higher security requirements, and operators' inherent high security awareness has also penetrated into the bones of OneNET. OneNET's ultra-powerful security capabilities will promote trusted computing of the Internet of Things, making it possible for applications such as smart door locks, energy meters, Internet of Vehicles, and smart wearables.
In terms of breaking data silos, OneNET has already got first successful cases. For example, OneNET participated in the "Intelligent Construction of Longhua, Wisdom Leading China" project, and cooperated with the Shenzhen Longhua Government to build Longhua New District into a "one network, one road, one cloud, one number" smart city demonstration area. Among them, one network is to use the Internet of Things to create a unified urban IoT perception system in the whole district; one way is to use the OTN backbone bearer network to create a unified high-speed communication transmission channel for the whole district; one cloud is to use the whole district to reduce various departments The self-built data center needs to greatly save investment; the first is to create a unified, standard, and shared big data support platform for the entire region.
5. 5G accelerates and matures smart cities.
Mobile communication networks are rapidly developing at a rate of replacement once every ten years. Now that the curtain of 5G commercialization has begun, the three major operators are racing to accelerate 5G construction. For example, China Mobile has vigorously promoted the "5G+" plan, and will launch "no card or number change" 5G services in more than 40 cities by the end of September 2019. The other two major operators are also intensively accelerating the deployment of 5G networks. The industry predicts that this year will usher in a year of large-scale 5G deployment. By 2025, 5G networks will become mature.
With the construction of 5G networks, the development of smart cities will gain a strong network foundation, and the R16 standard covering the two major standards of mMTC and uRLLC will be introduced, which will also give 5G networks more capabilities and make more smart application scenarios possible.
In the future, the IoT platform will solve the key problems in the development of smart cities and make up for the shortcomings of smart cities before the outbreak. 5G is like a catalyst to accelerate the maturity of smart cities. The superposition of two forces will bring smart cities on the fast-moving train. , As soon as possible to move towards the bright future of "5G changes society".
