On December 26-28, 2024, the high-profile China University Science and Technology Fair was held in Nanjing. This conference focuses on leading the development of new-quality productive forces with scientific and technological innovation, pooling scientific and technological innovation resources of universities, building a high-end platform for promoting and trading scientific and technological achievements, promoting collaborative innovation of government, Industry-University-Research and gold, and promoting more scientific and technological achievements of universities to be transformed into real productive forces.

At the scene, Taitong Technology and Nanjing University of Posts and Telecommunications demonstrated the achievement of the international cooperation project of the Ministry of Science and Technology jointly undertaken by the two parties in 2017-"New Generation Wireless Mobile Communication System for Intelligent Railways". The project has made key technical breakthroughs in the architecture design of the new generation railway wireless mobile communication network, the measurement and modeling of cross-band railway communication channels, the intelligent signal processing of train-ground communication, and the design of the satellite-train-ground railway communication Internet of Things: the LTE-R/5G-R network architecture with air-ground integration, the theory of large-scale MIMO transmission between train and ground and the design of communication system with the combination of historical data and edge calculation are proposed. Vehicle-ground integration, wireless sensing and wireless positioning combined with railway Internet of Things applications and other solutions have completed the development of LTE-R prototype equipment and system test verification, providing an important theoretical basis and technical accumulation for the development of railway 5G-R system equipment.

The achievements of Industry-University-Research science and technology project-the new generation of railway wireless communication 5G-R system has attracted much attention, attracting many leaders and guests to stop and watch and exchange.

Ji Rongxin, founder of Taitong Technology, and Wang Youguo, vice president of Nanjing University of Posts and Telecommunications, exchanged views on the spot.

Taitong Technology got to know the relevant person in charge of South China University of Technology through this exhibition, and signed a technical cooperation signing ceremony with South China University of Technology and Shenzhen Maihe Technology during the exhibition. Taking advantage of Taitong Technology's advanced equipment manufacturing and industry market ability in the field of rail transit wireless communication, South China University of Technology's leading scientific research ability in the field of electromagnetic metamaterials and antenna technology, and Shenzhen Maihe Technology's rich development experience and engineering implementation advantages in communication antenna series products, the three parties will carry out in-depth cooperation in the application of "transmission and reflection antenna technology based on paper-like honeycomb carrier" in the field of rail transit communication. The Lombard lens antenna of this technology has the characteristics of high gain and narrow beam, which is helpful to improve the wireless signal quality when the railway line is covered, and can also increase the distance between base stations and reduce the construction and investment cost of the station building.

Ji Rongxin, founder of Taitong Technology, was interviewed by CCTV.

At the China University Science and Technology Fair, Taitong Technology explained "leading the development of new quality productivity with scientific and technological innovation" with actions, which fully demonstrated the company's professionalism as the mainstream supplier of domestic railway communication systems. In the future, the company will continue to strengthen the Industry-University-Research cooperation mechanism with universities such as Nanjing University of Posts and Telecommunications, fully integrate and give full play to the resource advantages of all parties, jointly promote the transformation of scientific and technological achievements, and help the digital transformation and high-quality development of railways.
