China Telecom believes that under the reaction of the Internet of Things, the network will gain higher value, and the Metcalfe rule gives the square speed growth. The Internet of Things will allow the network to form a relationship of cubic value growth.
In the field of communications, Metcalfe's Law is the rule of leading industry development, which means that the value of the network grows at the "square" speed of the number of users. However, the Internet of Things may give the network a higher value. Ma Yimin, general manager of China Telecom Shanghai Corporation, believes that due to the reverse effect of the Internet of Things, the network will be given a "cubic" value growth relationship. Metcalfe's law means that the greater the number of users of a network, the greater the value of the entire network and each computer within the network; a network value equals the square of the number of nodes in the network, and the network The value is proportional to the square of the number of connected users.
Ma Yimin said in his speech that the concept of Metcalfe's law is more B2G, B2B and B2C. Because of the reverse action, the Internet of Things is not only B2B, but also B2I (Internet), which becomes a cube. Value relationship. In other words, through the three aspects of cloud, tube and end, different text, digital, image, voice, video and other heterogeneous data can be aggregated in the cloud. Take the actual case of animal husbandry, clothing industry, industrial manufacturing and retail consumption as an example to increase production and circulation efficiency through the Internet of Things. China Telecom cooperates with Weichai Power Machine Tool in the field of industrial manufacturing maintenance and management; in the retail field to share the consumption efficiency of the washing machine to enhance the customer's consumption experience, and realize the deep integration of the Internet of Things and the consumer information industry.
In the field of autonomous driving, integrated laser radar, front camera and Wi-Fi combined with 4G and 5G signals have improved self-driving speed, delay and reliability, while the Internet of Things and 5G will promote autonomous driving. Play a huge role. 5G communication technology is still human-centered, but Ma Yimin believes that the bigger change will be the connection between things and things. The essence of 5G is faster and newer communication technology, increasing speed, capacity and low latency, allowing more applications. Have more room to play. Among them, NB-IoT is the 5G prelude and foundation, which communicates with things and brings a better life experience and convenience.
Not long ago, the mainland released a special deployment plan for promoting IPv6. The current IPv4 to IPv6 conversion technology is very mature. It can introduce IPv4 private network addresses at the same time as IPv6. Ma Yimin believes that IPv is the foundation of the existence of the Internet of Things. In May 2017, China Telecom officially announced the completion of the mainland's complete NB-IoT network with 800 megabytes of frequency band coverage; in June, the mainland launched the first NB-IoT package in China; at the end of June, it released China Telecom's IoT open platform in Shanghai. All IoT manufacturers can access the platform for data interaction.
Shanghai is a mega city with tens of thousands of communities all over the city. It has great value for community management through large data. It provides community management of the 2017 White Paper Industry Development White Paper, aiming at the overall development trend, hotspots, and prospects of the Internet of Things. The three major challenges are analyzed. In the future, the external growth momentum of the Internet of Things will last for more than 10 years. Its kinetic energy includes infrastructure construction, industrial transformation needs, and consumption upgrading is a big driving force for the Internet of Things. The program, through 3D modeling, allows each community to conduct better urban governance.
Among them, the consumption upgrade field includes smart door locks, smart audio, smart retail, etc. to maintain rapid growth, while new technologies including blockchain and artificial intelligence continue to help the development of the Internet of Things; breakthrough and expansion of connection technology, Zigbee launched a new agreement, The global cellular Internet of Things, including NB-IoT and eMTC wide-area network technologies, has been rapidly developing accordingly.
