At present, the construction of a smart city has become an irreversible trend in our country to solve the problems of urban development and realize the sustainable development of cities. With the advent of new urbanization and integration of two cultures, the emergence of new opportunities, new models and new ideas in big data, Internet of things, low-power WAN, industry 4.0, PPP financing and government procurement services, Into the golden period of development. Internet of Things communications technology to promote smart city construction into the golden period of development As the first year of "the 13th Five-Year Plan" in 2016, "Smart City" is the first to be included in the government work report of the state government. Relevant policy documents are also emerging in an endless stream. Premier Li Keqiang repeatedly mentioned Smart Cities in domestic and international conferences. Yinchuan, China is listed as one of the 25 "National Model Cities for Information Consumption" in the world. Given Yinchuan's leading position in the global smart city construction industry and its outstanding contribution to the industry, TMF (Global Telecommunication Management Forum) plans to make Yinchuan the global smart city summit Permanent venue. Operators of smart cities in China have also gone abroad. Huawei took e-city successively to participate in the construction of smart cities in Mexico, Nigeria, Laos, Angola, Cuba and other countries. ZTE, as the world's leading smart city solution provider, Many countries take the floor. With the global leading IPv6 Mesh communications network, Rongwen actively participates in the construction of smart cities in cities such as Copenhagen, Chicago, Paris, London and Singapore, and utilizes the existing street lamp network to construct a smart city platform quickly and at minimum cost. Without having to take the time to set up and manage your own web platform - dramatically reducing the time and cost of your investment. As the most intensive urban infrastructure, street lamps play a key pivotal role in the construction of a smart city and become the natural entrance and the preferred breakthrough for smart cities. Wisdom street light also entered the "fast lane", the domestic ICT giant Huawei, ZTE and other strong intervention, to promote the construction of smart street lights in the technical level into a new stage of development. Smart city is the advanced stage of urban informatization development and the inevitable stage of deep integration of information technology and urban management. Choosing the right IoT communication technology and ensuring the high-speed and safe transmission of information are the necessary conditions for smart city construction. Rongwen uses the world's leading IPv6Mesh IoT communication network, which is the most widely used and open standard outdoor IoT communication technology in the world, and has the advantages of mature, scalable, high reliability and fast self-healing capability. The maximum communication rate 1.2Mb / s, is more than 4 times ZigBee technology. Compared with other communication networks, Mesh has the overall advantages: The current protocol used by the global Internet is the TCP / IP suite of protocols. IP is a protocol of the network layer in the TCP / IP protocol suite and is a core protocol of the TCP / IP protocol suite. IPv4 limited address space will be exhausted, the lack of address space will inevitably impede the further development of the Internet, but also can not meet the soaring demand for Internet of things, in order to expand the address space, Internet Engineering Task Force (InternetEngineeringTaskForce) designed IPv6 redefinition Address space, there are enough address resources to meet the smart city needs all things Internet address. In addition, compared with IPv4, IPv6 also has the advantages of improving router forwarding data speed, managing LAN more conveniently and quickly, adapting multimedia application more, enhancing network security, scalability and adding more functions. Rongwen selected IPv6Mesh IoT communication network, in addition to the above advantages, but also valued its 23.6 million in the world's smart city infrastructure equipment connection, proven. IPv6Mesh high-speed communications network from the United States Silver Spring Internet Corporation (SilverSpring), and now has become a global standard protocol open. To date, cities such as London, Chicago, Copenhagen, Glasgow, Melbourne, Mexico City, Paris, Sao Paulo, San Francisco, Singapore and Washington DC have all recognized and adopted the IoT protocol as a key infrastructure for smart cities. IPv6Mesh networking platform, not only to adapt to harsh environments outdoors, but also has a large outdoor network capacity to enable it to provide support for a variety of smart city applications in the same network platform to achieve real-time management of all types of information gathering equipment, and this It is the goal of smart city construction. As the smart city top planning department, we should first consider how to correctly select and construct one of the most important infrastructure, that is, IoT communication network and management platform. IPv6Mesh IoT communications network to meet smart city building equipment connectivity and communications needs over the next 10 years. In the future, as communication technologies are upgraded online, it will be able to carry larger numbers of smart city management devices and achieve faster information communication rates. Effectively avoid the duplication of the late network construction, a waste of manpower, material and financial resources. Fungho Industries (Group) Co., Limited , https://www.funghogroup.com
