Wireless Technology Builds a "World Where Nowhere" [Full Text]

It is regarded as the second largest “ubiquitous network” after the Internet. The wireless sensor network is a brand-new technology field that realizes the interconnection of objects and things and is called the “Internet of Things”. The wireless sensor network penetrates into industries such as logistics, electric power, and smart homes with its intelligent, low-power, and self-organizing features. It provides new intelligent communication and control methods, and may become a new and huge scale. The high-tech market reflects the prospect of huge industrial development. At present, many developed countries in the world have increased investment in this area and researched and developed new technologies in an effort to occupy a leading position. China has also included this technology development as a national long-term science and technology development plan.

The inspiration for the “Wireless Valley” project in Nanjing came from the wireless communication experts at Southeast University who visited Japan’s Yokosuka “Wireless Valley”. Japan's Yokosuka "Wireless Valley" - Japan's national laboratory: After its roots in Yokosuka, the Japan Institute for Information and Communication not only brought together nearly 10,000 researchers, but also attracted more than 60 wireless communication companies to gather around and make this world a reality. The highest level of "wireless valley." Japan first put 3G into commercial transportation in the world, and 4G technology also takes the lead in the world. "Wireless Valley" has played an important role.

As a powerful province of China's information industry, Jiangsu Province has always been at the forefront of similar cities in the country in terms of industrial development and digitization of cities. In recent years, the municipal party committee and government attached great importance to the development of the wireless industry and proposed the development plan for the construction of wireless broadband cities. It plans to build a wireless broadband network covering the whole city and the country in two years to lay the foundation for the construction of a smart city in the future. Since last year, Nanjing City has cooperated with Southeast University to launch the “China National Wireless Valley and National Communication Technology Laboratory in Nanjing” project, and listed it in Nanjing Science and Technology Innovation “No. 1 Project”.

Industry-university cooperation to build the world's high-end communications industry ecological community

China’s “Wireless Valley” is based on the existing two national key laboratories and a national engineering research center of Southeast University and is based on the Nanjing National Laboratory for Communications Technology to be built. The layout of the project will be divided into three circles. The first circle: East China Communications Technology National Laboratory as the core, mainly to build six research centers and a mobile communications comprehensive test field. The six research centers include core network and interconnection technology research and development center, wireless mobile communication network research center, communication radio and antenna research center, integrated circuit design research center, communication multimedia information processing technology research center and communication protocol and application software research center. The middle circle: It mainly constructs related companies and R&D institutions in universities, research institutes, cross-regional joint R&D institutions, public testing platforms, and engineering and technology centers. The third circle: High-tech enterprise cluster characterized by communication technology.

"By 2015, China Wireless Valley will realize a production value of 100 billion yuan and will gather more than 500 communications R&D, manufacturing and service companies." Yang Lianghu, deputy director of the Jiangning Development Zone Management Committee, specially introduced the "China Wireless Valley" strategic development plan - It is planned that in 10-12 years, Nanjing National Communication Technology National Laboratory of Southeast University will be used as a technology-dependent platform and long-lasting core technology driving force, relying on Nanjing to develop the foundation and advantages of the wireless communication industry, and building Wireless Valley into a world-class high-end communications industry ecosystem. Community, industry, academia and research institute spiral innovation demonstration area.

Extended Reading: About the "Internet of Things"

The so-called “Internet of Things” refers to a combination of various information sensing devices such as radio frequency identification (RFID) devices, infrared sensors, global positioning systems, laser scanners, and other devices and the Internet. Huge network. Its purpose is to allow all items to be connected to the network for easy identification and management. The Internet of Things is built using ubiquitous network technologies. One of the most important technologies is the RFID tag technology.

Based on a simple RFID system, combined with existing network technologies, database technologies, middleware technologies, etc., to build an Internet of Things that consists of a large number of networked readers and innumerable mobile tags, which is larger than the Internet, becomes the development of RFID technology. the trend of. In this network, the system can identify, locate, track, monitor and trigger corresponding events automatically and in real time.

The relatively well-established distributed network integration framework is the EPCglobal EPC network. EPC network is mainly aimed at the logistics field. Its purpose is to increase the visibility and control of the supply chain, so that the entire logistics field can use RFID technology to obtain greater economic benefits.
