Urbanization is one of the most important socioeconomic phenomena in the world today. About 50% of the world's population currently lives in cities, and as urbanization continues to accelerate, this proportion is expected to exceed 70% by 2050. As the population continues to gather in cities and new metropolises and urban agglomerations are formed one after another, problems such as traffic congestion, environmental deterioration, lack of resources, and decline in residents’ quality of life caused by urbanization have become increasingly prominent. How to achieve sustainable development of cities has become Issues of concern to city managers. In this context, the concept of smart city emerged. Smart city system "Smart city" is a new perspective on cities, a new way of thinking about developing cities, and a continuation of digital city construction. It is of great significance in urban planning, management, operation and long-term development. In 2010, IBM officially proposed the vision of "smart cities", hoping to contribute to the urban development of the world and China. After research, IBM believes that cities are composed of six core systems of different types of networks, infrastructure and environment related to the main functions of the city, including: 1. Organization (people), 2. Business/Government Affairs, 3. Transportation, 4. Communications, 5. Water and 6. Energy. These systems are interconnected collaboratively, and the city itself is the macrosystem composed of these systems. The construction of smart cities is a multi-dimensional and systematic project. Urban planning and information technology planning such as smart cities must be highly integrated. The development of modern cities is driven by digitalization, and the application of leading digital and smart technologies must be considered in the urban planning process. In the same way, when planning smart cities, the development pattern of the city also needs to be considered. Smart cities in the 21st century should make full use of information and communication technology to sense, analyze, and integrate key information of the city's core operating systems, to provide information on people's livelihood, environmental protection, public safety, urban services, and industrial and commercial activities. Only by responding intelligently to various needs can we create a better urban life for mankind. Empowering smart cities As the latest generation of wireless communication technology, 5G has had a huge impact on the construction of smart cities with its ultra-high speed, ultra-low latency, and ultra-large connection characteristics. The ubiquitous sensor network based on 5G can deeply integrate the development of people, machines and things, and realize the intelligent connection of everything in smart cities. At the same time, 5G can also be deeply integrated with the new generation of information technology represented by cloud computing, big data, artificial intelligence, and the Internet of Things. By using the 5G network, network resources can be flexibly configured according to end-application scenarios to meet the differentiated network needs of smart cities. Therefore, 5G wireless communication technology will become an important capillary supporting urban development and empowering smart cities. When foreign cities are planning smart cities, they regard network communications as another important infrastructure in building smart cities in addition to physical facilities. Early smart city construction was mainly driven by technology and lacked top-level design and unified planning. At that time, the focus of smart city development was on digital construction, which was supported by urban information infrastructure such as networks and data, and used remote sensing technology, geographic information technology, and global positioning systems to collect and monitor information. However, today's new smart cities have multi-layered requirements for infrastructure such as network bandwidth, coverage and speed. With the arrival of 5G new technology, countries have also begun to actively upgrade communication network construction and promote the construction of smart cities through 5G commercial deployment. 5G communication network resources play an irreplaceable and important role in the infrastructure construction of smart cities. In response to the various challenges in smart city construction, how to provide efficient basic network facilities and connection services while jointly undertaking the development and construction of smart applications with partners in the smart city ecosystem, and building an ecological environment to achieve co-construction and co-governance The new pattern of sharing is an important issue that telecom operators need to consider in the construction of new smart cities in the 5G era. Achieve collaborative intelligence The competitive advantage of China's 5G industry lies in independent innovation and open cooperation. Especially in the era of economic globalization, the industries of various countries are deeply integrated. Without extensive and close international cooperation, the pace of 5G will not be so rapid. Over the years, from the Chinese company Huawei opening a 5G wireless network open laboratory in Seoul, South Korea, to China, Russia, and China working together to promote the construction of a new generation of 5G networks, the development of the 5G industry will achieve collaborative intelligence, share a new generation of information technology, and bring benefits to the world. more surprise: 1. Artificial Intelligence With the intelligent upgrading of residents' lives, urban management, and operation and production, there is a strong demand for new-generation artificial intelligence technologies, products, services, and solutions. 5G can meet the concurrent access requirements of massive smart devices in smart cities, respond to virtual and real interactions between devices at the millisecond level, promote the implementation of multi-scenario applications of artificial intelligence, and truly realize the intelligent connection of all things. Artificial intelligence technology represented by deep learning will be rapidly popularized, promoting scientific decision-making by city managers and improving the wisdom of public services. 2. New IoT terminals and IoT As the infrastructure of the new generation network, 5G is the cornerstone of the intelligent connection of all things. The wide-connectivity feature of 5G will further enhance the deployment of smart terminals and realize ubiquitous connections between people, people and things, and things and things. Through sensory and IoT methods, we connect and collect various data and information in the city, building a huge peripheral nervous system in the city, providing solid support for the construction of "digital twin cities", and helping city managers to be more efficient, Accurately grasp and manage city information. 3. Big data analysis Data is an important strategic resource in the future. 5G's large bandwidth and multiple connections enable big data analysis processes such as data collection, data fusion, data modelling, and data mining to extract valuable information from complex and redundant urban data. Intelligent terminal sensors in smart cities will generate a large amount of valuable data. Through big data analysis, they can promptly and effectively assist city managers in scientific management and decision-making. 4. Cloud computing Through cloud computing technology, physically dispersed computing capabilities can be integrated to achieve the highest efficiency recovery for urban data storage and processing at the lowest cost. Cloud computing has the advantages of elastic computing and on-demand billing, and information resources can be coordinated and shared to the greatest extent through the "cloud". The large bandwidth of 5G will allow cloud computing to store a larger amount of data. The low latency will allow data to be uploaded in a more timely manner. The larger load capacity will allow more devices to connect to the cloud, promote cloud-edge collaboration, and make the business more efficient. 5. Blockchain 5G intelligent connection of all things brings a large amount of end-to-end information exchange, especially information exchange in large-scale business scenarios, which have stricter security requirements. The integration of the underlying distributed ledger technology of blockchain with 5G can be applied to information authentication, address, identification and other management, as well as spectrum resource sharing, etc. It can also change the business model and system architecture of future networks and realize the transformation from an information network to a value network. changes to realize the value of network and information assets. Unleash urban potential On June 6, 2019, the Ministry of Industry and Information Technology officially issued 5G commercial licenses to China Telecom, China Mobile, China Unicom, and China Radio and Television. China officially entered the first year of 5G commercial use. With the construction, deployment and commercial use of 5G networks, making good use of the characteristics of 5G networks to empower vertical industries has become one of the most talked about topics in the development of smart cities. In 2020, Deloitte Technology, Media and Telecommunications Industry joined hands with China Unicom to compile the "5G Empowering Smart Cities White Paper". This white paper examines the development trends of smart cities in the 5G era, focuses on typical application scenarios of 5G in transportation, security, environmental protection, governance and other fields, and proposes the main challenges and implementation paths for smart cities in the current 5G era, as well as the thoughts of operators in promoting the construction of smart cities in the 5G era. Effectively promote the implementation of 5G smart cities across the country.

Zhang-Ni, Reporter from Global Times Shelley Tsang, Co-founder of Gaudi Digital Museum and Founder of Gaudi Asia Pacific Research Institute Zhang-Ni: What are the reasons for the launch of the Gaudi Digital Museum? Shelley Tsang: The world's first Gaudi Digital Museum jointly built by the Gaudi Asia-Pacific Research Institute, Gaudi World Congress and Baidu Encyclopedia, displays the life of Anthony Gaudi, innovative thinking and architectural works diversely through the Internet. We hope people can learn from the magical world of Gaudi through the Internet by breaking time and geographical restrictions. To build an international high-quality online museum, Gaudi Asia-Pacific Research Institute and Gaudi World Congress integrated our Gaudi-related resources in more than 20 countries for the first time. The Spanish government, universities and research institutes, the Gaudi Museum in Barcelona, ​​the owners of Gaudi architectures, international scholars studying Gaudi and architects inspired by Gaudi's works were invited to contribute to the contents of our Gaudi Digital Museum. We have also invited international authoritative Gaudi scholars to explain Gaudí's innovative thinking methods and the essence of Gaudi's architectural works. The Gaudi Digital Museum project has been appreciated and recognised by many scholars and prominent leaders of the Spanish government. Both Chinese and foreign scholars believe that Gaudi Digital Museum is not only an essential channel for cultural exchange between China and Spain but also a global Gaudi knowledge network. This critical knowledge network will be of great significance. Zhang-Ni: Why do you choose to cooperate with Chinese companies? What are the advantages and special features of China in building a digital museum? Shelley Tsang: Most people do not know that Gaudi has a deep relationship with China. Gaudi has ​​a close friend named Eduard Toda i Güell, who grew up together. Toda became a diplomat at the Spanish embassy in China at the end of the Qing Dynasty and lived in China for six years. During this time, Toda collected many coins, cultural relics, materials and photos in China. After Toda returned to Spain, he shared his knowledge and collections with Gaudi and wrote many essays and books on China. Gaudi was influenced by Toda and was very obsessed with Chinese culture. From the earliest Gaudi architecture, you can see that Gaudi used many elements of Chinese architecture and naturalistic architectural philosophy. I think Gaudi and China is an exciting direction and a worth discussing topic. Therefore, we suggest connecting with Chinese scholars and institutions to discover and study the history and stories of cultural exchanges between China and the West and spread our research through cooperation with Chinese companies. We chose to conduct in-depth international cooperation with Baidu, mainly considering several advantages and special features of Baidu: 1. Baidu is well-known in China and the world. Baidu is the most popular Chinese search engine. Through Baidu platform, we can access most of the Chinese Internet users in the world. 2. Baidu is an excellent and forward-looking company in Internet development and technology applications. Baidu has brought us a lot of modern content display methods in a high-tech way, and to promote the development of Gaudi Digital Museum. Baidu generously provided Gaudi Digital Museum with its latest technology and internal resources, which is very valuable. 3. Baidu has been developing the platform of Baidu Baike Museums Project since 2012. Now it has included more than 1,600 Chinese museums and launched more than 220 Chinese museums. They are committed to doing great things for the benefit of the country and the people, and they are all aware of their contribution to cultural communication, which is consistent with our philosophy and vision. We believe that through cooperation between the two sides, we can achieve larger international cultural projects linking China and the world. Zhang-Ni: Unlike on-site visits, what different experiences will Gaudi Digital Museum bring to the audience? Shelley Tsang: The Gaudi Digital Museum will use artificial intelligence, short videos, panoramic pictures, VR and other technologies to present online the architectural works, precious manuscripts, photographs of the times and related cultural research results of Antoni Gaudi. As the world's first Gaudi Digital Museum, with the support of Baidu Encyclopaedia's online authoritative platform, Chinese audiences can enjoy precious exhibits in various forms through audio explanations, reality simulations, and stereoscopic presentations. Besides, the Gaudi Digital Museum specially invited authoritative international experts to explain the versatility of the genius Gaudi, including Gaudi's thinking, his concepts on innovation, the technological breakthroughs, creative inventions and decisive actions to promote social development. You can feel the historical and cultural accumulation and the cultural connotation behind it at any time. You can be inspired by the genius thinking and apply the spirit of innovation to your daily work life. Zhang-Ni: Will the digital museum be a big trend in the future? Why? Will it replace the on-site visit? Shelley Tsang: I believe that digital museums are a big trend. The Internet and "Internet+" are already an indispensable part of contemporary life. High-quality content will become a huge demand for the development of the global Internet, and the digital museum happens to be a unique and effective form to spread knowledge and promote cultural development. However, I don't think digital museums will replace on-site visits. The on-site visits give the audience a personal experience that is irreplaceable. To be precise, the digital museum is a shared network of human knowledge system. Each digital museum is more like a door linking different content, attracting different people to open the door to explore the knowledge content where they have the interest. With the help of the Internet, everyone can break the limits of space and time, and achieve their targets on in-depth research and development. I believe the future is an era in which science and technology promote the spread of knowledge and enhance the development of culture. The development of science and technology and the human knowledge system will be tightly bound together. At present, it is valuable and forward-looking to build a global knowledge network in the form of a digital museum. Zhang-Ni: What kind of institution is the Gaudi Asia-Pacific Research Institute? What is its background, attributes and primary responsibilities? Shelley Tsang: Our Gaudi global projects are a group of large-scale, long-term plans for over ten years. It is a worldwide collaboration platform linking hundreds of organizations in more than 20 countries around the world, in-depth research topics from social, ideological, innovative, aesthetic and other aspects the genius of Gaudi. Through Gaudi Asia-Pacific Research Institutes and other partners, we integrate these resources and research to publish and share the latest scientific research results to promote science and technology and cultural developments. The Gaudi World Congress was established in 2012 to disseminate all scientific literature on Anthony Gaudi accumulated by The Gaudi Research Institute and the world's most prestigious universities over the past 40 years. Gaudi World Congress is the only platform in the world where Gaudí's authoritative experts can gather to share Gaudí's research results. The main projects of the Gaudi Asia-Pacific Research Institute focus on organizing conferences and exhibitions, teaching Gaudi's working methods, participating in museum content planning, and consulting in the fields of engineering, architecture, and sustainable urban planning. Zhang-Ni: In addition to the current Gaudi projects, what practical measures have the Spanish government and institutes adopted to protect, inherit and spread the ideas of Gaudi? What are the problems and obstacles of the spread of Gaudi culture around the world? What relevant measures does Spain hope to take in the future? Shelley Tsang: Rather than saying we are spreading Gaudi's ideas around the world, it is better to say we are "rediscovering" how we live today from the origins. Gaudi's influence on future generations is very far-reaching. Gaudi inspires many innovative ideas, architectural philosophy, thinking methods, mathematical discoveries, mechanical innovations, environmental protection concepts and working methods. These ideas and techniques are widely used in our lives, but we know very little about how they come to us. Therefore, this is a rediscovery process for us to discover ourselves and explore the future through understanding Gaudi. The main challenge for the promotion of Gaudi ideas around the world is the language, but this is not "problems and obstacles." Spanish is one of the three major language systems ​​in the world. Gaudi has extensive recognition in the Spanish region. After leaving the Spanish-speaking area, due to the language and cultural differences, communication between Spain and the Chinese-speaking area is relatively weak. Therefore, the materials and contents accessible to the public in the Chinese-speaking area are inadequate, and there is a lack of professional international cultural institution to promote Gaudi and Spanish culture. I feel sad for the current status of cultural exchanges between China and Spain, so I established the "Gaudi Asia-Pacific Research Institute" in Asia. Starting from Gaudi, I believe we will break the restrictions between the two languages and promote in-depth communication and cooperation between Spain and China. My ideas and actions have been recognized and strongly supported by prestigious cooperative institutions such as the Spanish Central Government, Provincial Government, Local Government, Ministry of Culture, Ministry of Tourism, and major museums. At this stage, the primary goal of Gaudi Asia-Pacific Research Institute is to collect and translate authoritative information of Gaudi and Spanish culture through the platforms and support of various partners. We will be providing high-quality content and making sure these contents are effectively disseminated in Chinese-speaking regions. Zhang-Ni: In your opinion, what are the most prominent feature and contribution of Gaudi? What particularity does it reflect in Spanish culture? Shelley Tsang: Antoni Gaudi is a Spanish national treasure and the originator of modern Western architecture. At present, of the works of Gaudi, 17 are listed as national cultural heritage in Spain, and seven are listed as World Cultural Heritage by the UNESCO. Spanish culture is a culture with diversification. In addition to the local Spanish culture, you can also see the influence of Arab, African, European and South American cultures on Spanish culture. These different cultures fuse to form a splendid and passionate Spanish culture. In Gaudi's works, this multicultural fusion can also be seen everywhere. It is not only the characteristics of Gaudi but also the features of Spanish culture. Gaudi's art has a far-reaching influence. For the 20th century, many innovative ideas, architectural philosophy, thinking methods, mathematical discoveries, mechanical innovations, environmental protection concepts and working methods were inspired by Gaudi. The three major modern art giants of the 20th century, Picasso, Dali and Miro, are all deeply influenced by Gaudi as well. Dali, especially, has repeatedly expressed his love and respect for Gaudi. In the future, after sorting out the influence of Gaudí's impact on future generations, we will put the information to update the Gaudi Digital Museum and gradually show the discoveries of the unknown Gaudi.
